“What do you think about my audition(试奏) yesterday？My trill(颤音) should have been better, don’t you think？” Abbie asked Mel and closed the lid of her violin case before school.

“It’s no big deal, Abbie, ” Mel said as they walked out the door. Mel didn’t have time to worry about her little sister’s mood. It turned out to be a busy day. She had a test in science class. She hit two home runs in softball. After school, she and her friends talked about their summer plans.

She forgot about the audition results until Abbie dragged her to the music room. Mel thought she’d probably be in the first violins.

Mel and Abbie found the list of names on the board. Abbie. Concertmaster. Abbie screamed, “I can’t believe it!” “I can’t wait to tell Mum and Dad!” Abbie rushed toward home. Mel kept reading. Mel. Second violins. What？There had to be some mistake. She’d figure out tomorrow.

When Mel got home, Abbie was playing her audition piece there. Music poured from Abbie’s bow like water from a teapot—pure and perfect. And the trill sounded like a bird singing. Abbie was good—really good—but that wasn’t the point. “Mr Benson must have made a mistake, ” Mel thought.

The next morning, Mel slipped into the music room. Gathering her courage, Mel said, “Mr Benson, I want to talk to you about the orchestra(管弦乐队) seats. ”

“Yes—you must be proud of your sister, ” Mr Benson smiled. “Abbie is a rare student. If she continues to practice hard and grow as a musician, she could become a professional. Then we’ll look back on our little orchestra and think about how lucky we are. ”

Paragraph 1：

Mel froze as there wasn’t any mixup.

Paragraph 2：

After school, Mel found Abbie on a bench outside, playing the violin.

It may not be the best way to go about meeting new people, but chat rooms are still among the most popular channels. Want to chat with a stranger now? 1., after which, you need to keep the following rules in mind.

2.. Details such as your phone number and home address or where you attend classes should remain personal. It is actually not a very good idea to share your last name with a stranger. Even if you feel you have met someone you really like and get along with, it is still necessary to withhold some important details.

Be fun and chat about something personal. This doesn’t mean giving away personal details, but you can share your life experiences and stories with strangers as long as you are both going with the flow. There is really no way you will manage to know the strangers better unless you both go beyond your hobbies. 3..

Remain in control at all times. There is really no obligation on you to continue with chats that scare you or make you uncomfortable. 4.. As soon as something annoys you, feel free to leave the chat. Let nobody force you into conversations you find inappropriate.

Try not to download things from strangers. 5., but be careful that you don’t get viruses or hacked by such downloads. You really can’t be sure of who you are talking to, so be cautious about downloads. It is best that you stick to the channels of communication made available to you and also make sure that you have the right computer protection even when you download things.

A. Chat rooms make it possible to share all manner of files

B. Avoid sharing your personal details with random strangers

C. So do not be afraid to get a little personal in your random chats

D. At night it’s not appropriate for teens to stay in chat rooms alone

E. Many files with viruses are often purposefully spread on the website

F. Then you should start by finding a chat room reflecting your interests

G. Remember you are chatting for fun and you should remain fully in control

Fairs and theme parks never seem to lose their attraction. My kids love them as much as I do. Not everyone will agree with me though. My wife is terrified of anything more exciting than the merrygoround. So why do I love Blackpool’s Big One while she goes white on hearing the word “rollercoaster(过山车)”？

According to psychologists, it comes down to something called a “Type T” personality. Type T’s are thrillseekers who welcome the uncertainty of activities that most people would find hairraising. It seems some of us enjoy the physical sensations associated with fear: the adrenaline(肾上腺素) rush and the beating heart. Scary rides make us feel alive. Terrifying experiences encourage a sense of excitement once we’re back on solid ground though we only enjoy them, experts say, when we’re within a “protective frame” that assures us that deep down, we’re still safe.

Recent research has found certain genes(基因) which may be responsible for those of us with Type T personalities. Biochemists have separated a gene called DRD4 which seems more common in rollercoaster lovers like me.

New technologies have allowed engineers to design coasters that change speeds quickly, shoot up hundreds of feet into the air and make all sorts of twists. Research suggests that extreme fairground rides tend to appeal particularly to those of us who lead stressful, structured or controlled lives. It’s certainly true that roller coasters are a way of breaking out of the humdrum(乏味的) expectations of everyday life. Theme parks allow us to act like children again, to experience true excitement and behave a little wildly. Where else as an adult can you scream at the top of your lungs and throw your arms in the air without being sent for psychological evaluation?

If you’re looking for a great place this summer where you can get in touch with your inner risktaker, head for the nearest theme park. It’s a scream!

1.What can we learn about the author’s wife?

A.She gets excited easily.

B.She fears extreme rides.

C.She loves Blackpool’s Big One.

D.She rarely disagrees with the author.

2.What do people with Type T personalities tend to do?

A.Put their lives at risk.

B.Stay energetic all the time.

Even for a first-time visitor to China, it is impossible to ignore the popularity of Quick-Response (QR) codes. These square-shaped black-and-white symbols in WeChat or Alipay where QR codes are scanned to add new friends or make payments.

The QR Code system originated in Japan. The engineer Masahiro Hara felt the limitation of the one-dimension barcode in use and thus developed the QR codes which could carry data horizontally and vertically. QR codes could hold much more information than barcode due to their extra dimension. In addition, QR codes have larger data capacity, smaller print—out size and higher resistance to dirt and damage, which make them widely applied in many other applications.

Though the technology of QR codes is complicated, we can easily create our own QR codes with the help of QR code generators, many of which are available online for free. Users could enter the data they wish the QR code to display, and the generator turns it into a symbol that can be printed or displayed in electronic form. The process of creating QR codes could be really fun when we customise the design of the codes according to our specific needs. For instance, we can adjust the color, add a logo, and create social options etc. Moreover, dynamic (动态的) QR codes are also available. They are more various than standard QR codes because they allow users to edit data entered previously whereas data in standard QR codes cannot be edited once printed. Plus, don’t limit your QR code to one mobile scanner. Anyone can scan your code with any reader. A lower barrier to entry makes success more likely for you and the user.

Meanwhile, we must also recognize the vulnerability of QR codes. Due to its easy access, criminals can steal simply by replacing the QR codes with their own, routing cash into their own bank accounts. Hence, we should all become more conscious towards virtual money transactions through QR codes and participate in additional security measures.

1.Which of the following is NOT a function of QR codes?

A. Data storage.

B. Scanning reader.

C. Social networking.

D. Mobile payment.

2.Why is barcode mentioned in paragraph 2?

A. To introduce the main topic.

B. To show the author’s attitude.

C. To highlight the features of QR codes.

D. To add some background knowledge.

3.Which of the following best explains “vulnerability” underlined in paragraph 4?

A. Threat. B. Weakness.

C. Difficulty. D. Simplicity.

4.Which is true about QR codes according to the text?

A. They were first used in China.

B. The generators charge the users a lot.

C. Data editing is possible in printed QR codes.

D. More scanning devices are available in reading QR codes.

Elizabeth Garrett Anderson was born on 9 June, 1836, in Whitechapel, East London. She was expected to marry well and live the life of a lady. However, meetings with the feminist(女权主义者) Emily Davies and Elizabeth Blackwell, the first American woman physician, convinced Elizabeth Garrett that she should become a doctor.

This was unheard of at that time and her attempts to study at a number of medical schools were refused. She enrolled(入学) as a nursing student at Middlesex Hospital and attended classes for male doctors, but was driven out after complaints from other students. As the Society of Apothecaries did not specifically forbid women from taking its examinations, in 1865 she passed their exams and gained a certificate which enabled her to become a doctor. The Society then changed its rules to prevent other women entering the profession this way.

In 1866, she set up a clinic for women in London, thanks to her father’s backing；in 1870 she was made a visiting physician to the East London Hospital. There she met James Anderson, a successful businessman, who she married in 1871.

In 1872, Anderson founded the New Hospital for Women in London, staffed entirely by women. She appointed her spiritual guide, Elizabeth Blackwell, as a professor there.

Anderson’s efforts paved the way for other women, and in 1876 an act was passed permitting women to enter the medical professions. In 1883, Anderson was appointed to manage the London School of Medicine for Women, which she had helped to found in 1874. It was the first medical school in Britain to train women as doctors.

Anderson, Britain’s first female doctor, retired in 1902. Six years later, she became the mayor(市长) of Aldeburgh, the first female mayor in England. Anderson died on 17 December, 1917.

1.Why did the Society change its rules?

A.To provide certificates for women.

B.To forbid women to take its exams.

C.To offer programs to train women doctors.

D.To encourage women to attend medical schools.

2.What was Anderson’s father’s attitude to her career?

A.Supportive. B.Doubtful.

C.Sympathetic. D.Critical.

3.What did Anderson do after founding the New Hospital for Women?

A.She married a successful businessman.

B.She started a clinic for women in London.

C.She learned at a hospital as a visiting physician.

D.She helped create a school to train female doctors.

4.Which of the following can be used to describe Anderson?

A.Strict. B.Sensitive.

C.Determined. D.Modest.

Listening to English radio programmes help me get used to how fast native speakers talk. I also repeat which I hear to help myself experience with the feeling of the language. Sometimes I even recorded my voice so I can listen to me and compare my pronunciation with the radio hosts’! My biggest headache is how to polite in English. It's much easy to just say “Open the window !" in Chinese than in English, where that can sound real terrible.

The first time I went to a playground in Berlin, I was surprised. All the German parents were huddled together, drinking coffee, not paying attention to their children who were hanging off a wooden dragon 20 feet above a sand pit. Contrary to stereotypes(模式化观念)，most German parents I’ve met are the opposite of strict.1.. Those parents at the park weren’t ignoring their children; they were trusting them. Here are a few surprising things Berlin ’s parents do:

Don't push reading. Berlin ’s kindergartens don’t emphasize academics. In fact, teachers and other parents discouraged me from teaching my children to read.2.. But even in first grade, academics aren’t pushed very hard. Our grade school provides a half-day of instruction interrupted by two outdoor breaks.

3. A note came home from school along with my excited second grader. They were doing a project on fire. Would I let her light candles and perform experiments with. matches? Together we lit candles and burned things, safely. It was brilliant.

Let children go almost everywhere alone. Most grade school kids walk without their parents to school and around their neighborhoods. Some even take the subway alone.4.of course, but they usually focus on traffic.，not abductions(绑架).

Take the kids outside every day. According to a German saying, “There is no such thing as bad weather, only unsuitable clothing.”The value of outside time is promoted in the schools.5.No matter how cold and grey it gets, and in Berlin it gets pretty cold, parents still bundle their kids up and take them to the park, or send them out on their own.

A.Encourage kids to play with fire

B.Inspire children to go out for leisure

C.German parents are concerned about safety

D.It's also obvious on Berlin ' s numerous playgrounds

E.Kindergarten was a time for play and social learning

F.They place a high value on independence and responsibility

G.I was told it was something special that the kids learn together when they start grade school

Back in 1975, economists planned rising life expectancy (预期寿命) against countries’ wealth, and concluded that wealth itself increases longevity. It seemed self- evident: everything people need to be healthy--from food to medical care- costs money.

But it soon proved that the data didn't always fit that theory. Economic booms didn’t always mean longer lives. In addition, for reasons that weren’t clear, a given gain in gross domestic product (GDP) caused increasingly higher gains in life expectancy over time, as though it was becoming cheaper to add years of life. Moreover, in the 1980s researchers found gains in learning were associated with greater increases in life expectancy than gains in wealth were. Finally, the more educated people in any country tend to live longer than their less educated fellow citizens. But such people also tend to be wealthier, so it has been difficult to make out which factor is increasing lifespan.

Wolfgang Lutz and his colleagues have now done that by collecting average data on GDP per person，lifespan, and years of education from 174 countries, dating from 1970 to 2010. They found that, just as in 1975, wealth associated with longevity. But the association between longevity and years of schooling was closer, with a direct relationship that did not change over time, the way wealth does.

Lutz argues that because schooling happens many years before a person has attained their life expectancy, this association reflects cause: better education drives longer life. It also leads to more wealth, which is why wealth and longevity are also associated. But what is important, says Lutz, is that wealth does not seem to be longevity, as experts thought- in fact, education is driving both of them.

He thinks this is because education permanently improves a person’s cognitive abilities, allowing better planning and self-control throughout the rest of their life. This idea is supported by the fact that people who are more intelligent appear to live longer.

1.Which of the following best describes economists ’conclusion in 1975?

A.Lifespan could be increased by wealth.

B.Economic growth didn’t always mean longer life.

C.Education influenced longevity more than wealth did.

D.A given growth in GDP caused higher gains in longevity.

2.What did Wolfgang Lutz and his colleagues find?

A.Wealth and longevity did not have any association.

B.Longevity and education were more closely associated.

C.Differences in wealth predicted differences in longevity.

D.Relationship between education and longevity changed over time.

3.What part does education play permanently according to Lutz?

A.It enables people to have better planning and self-control.

B.It always leads to a longer but not necessarily richer life.

C.It improves people’s imaginative and innovative abilities.

D.It helps people acquire time-managing and learning habits.

4.Which of the following is the best title for this passage?

A.Wealth influences longevity.

B.Education influences longevity.

C.Wealth has nothing to do with longevity.

D.The relationship between education and wealth.

It often seems that some people possess superhuman eating powers, allowing them to eat an entire pizza while remaining slim. Others only eat a slice but gain five pounds. Now one doctor says there' s evidence that genetics could be behind some of these differences. Regardless of how much you eat, your weight may be out of control.

Vann Bennett, a biochemist at Duke University and his team led a new study and discovered why this happens. They engineered mice to have several common modifications of the gene found in humans. They observed that mice who had mutations of ankyrin-B(锚蛋白B的变异) took more glucose(葡萄糖) into their fat cells, which in turn made more fat. Typically, the cell membrane( 膜) acts as a barrier to prevent glucose from entering these cells ; the change kept the gate open. The change may serve a useful purpose. “ Probably this is not always a bad thing,” Bennett told Newsweek. “It could help people survive hunger in the past. But today we have so much food that it probably is a bad thing.”

Dieters have long been told to watch their calories and exercise more, but this new finding suggests that a common approach doesn't work for everyone. Our metabolism( 新陈代谢) naturally slows with age, making it harder to maintain the weight of our 30-year-old selves when we' re 50. Now add an uncontrollable ankyrin-B gene, and it may seem impossible to stay slim.

The mice in the study gained more weight when on high-fat diets. Despite being studied in mice, the researchers believe further research on this gene could potentially create a field of customized diets and health plans based on genetics. Bennett imagines such assessments being performed at birth one day. For now, disappointed dieters can take comfort with one saying: It's not you, it's your genes.

1.How did a mouse gain weight with mutations of ankyrin-B?

A.The ankyrin-B could make the mouse eat more.

B.The fat cells in the mouse would take more glucose to create more fat.

C.The glucose could function as a barrier to prevent the fat from reducing.

D.The cell membrane in the mouse could open the gate of fat into the mouse.

Keeping your teenager out of the social media world is impossible. Whether we like it or not, our kids are growing up in a digital era- -and although that creates major opportunities, it also comes with some pretty big risks. We saw this firsthand when we asked a group of tweens and teens to give up their phones and social media for a week; it was as though we’d asked them to part with a limb.

A recent study of more than 10 ,000 six- to twelve-grade girls carried out by a nonprofit organization Ruling Our Experiences found that high school girls spend an average of six hours a day on social media. And the effect of too much logged-on time is clear. The study found kids who spend eight hours or more on technology per day are five times more likely to be sad or depressed. Adding to the pressure is that2 out of 3 high school girls report being asked to send a revealing photo to another person, and most of them report that they do send sexual texts and photos to each other.

Another study, carried out by Common Sense Media, found that girls use social media more than boys and are also more likely to experience negative consequences. Most of the girls investigated admitted that content posted online often makes them worry about their appearance or social status, while just a quarter of the boys said the same. An earlier study from the Pew Research Center’s Internet came to a similar conclusion: A third of 12- to 13-year-old girls who used social media believed their peers were mostly unkind to each other online , while only 9 percent of the boys agreed.

Of course, these differences don' t mean we shouldn’t have concerns about boys and the impact of digital overload or online bulling. In fact, other studies have shown that boys and girls can be equally damaged by social media. The most important thing is for teens to feel safe, online and in the real world alike.

1.What is the second paragraph mainly about?

A.The pressure of the high school girls logging-on.

B.The influence of too much logged-on time on high school girls.

C.Too much time spent on social media for high school girls.

D.The increasing population of the high school girls logging-on.

2.Which of the following can replace the underlined word “revealing” in paragraph 2?

A.Exposed. B.Interesting.

C.Funny. D.Romantic.

3.Why are the girls more likely to experience negative effect online than boys?

A.Because the girls' social status is low.

B.Because the girls are mostly unkind to each other.

C.Because the girls use social media more than boys.

D.Because the girls pay more attention to their appearance.

4.What can be inferred from the passage?

A.Parents should keep teens out of the social media.

B.Parents keep teens feel safe online and in the real life.

C.It is time to worry about your teens and social media.

D.Boys and girls can be equally damaged by social media.

When you start a new job, you’ll probably be introduced to a lot of new people on your first day. And it’s important to make a good impression. The following are some practical tips to help you.

Show up early

This might seem easy, but many people don’t do it.1. .To make sure you can arrive early, give yourself extra time to get ready in the morning and to travel to your destination.

It can be difficult to find the right balance between having an influence on your new role, and disturbing the balance of the delicate office ecosystem. You don’t want to walk in and get into trouble, but you also don’t want to fade into the background, either.

Take plenty of notes

It’s a great idea to bring a small notebook and pen with you on your first day for taking down notes. Don’t be shy about recording information that you know will be useful to you later, like names and passwords. You’re likely to face data-overload on your first day.3..

Watch your body language

You’ve probably read that body language is important for job interviews, but it can also be a valuable tool in creating a lasting impression when you start a new job. On your first day, be careful of conveying powerful body language. 4..And do your best to avoid negative body language, such as yawning, frowning, or standing with your hands in your pockets.

Step away from social media

While on your first day at the office you must have all sorts of feelings—nerves, anxiety, joy, even boredom—resist the desire to share it on social media. When it comes to updating your friends and followers about the status of your newfound employment, always be cautious and assume your bosses are watching. 5..

A. Almost certainly, they will in fact

B. Be positive and show interest

C. Be enthusiastic, but not overbearing(自大的)

D. Smile often and look people in the eye

E. Body language is what we should avoid

F. Arriving 5 to 10 minutes early gives you time to settle in

G. So taking notes is a great way to keep on top of things

Tablets（平板电脑） are useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn’t it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand? Now something like a tablet-shaped but foldable（可折叠的） phone is about to become available. In February, Samsung and Huawei both introduced foldable phones, the Galaxy Fold and Huawei Mate X separately, to the public for the first time. Mobile phone use has entered the “foldable future”, the Verge noted.

The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want but still fit easily into the pocket. The technology could change other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers, which could help increase available space to the maximum. In a keynote address, Justin Denison, Samsung’s senior vice president, called the foldable screen “the basis for the smartphone of tomorrow”. “It’s a blank canvas (画布) for us to do something beautiful together,” he said.

So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of ten foldable screens produced were defective or unusable. Today, that 10 percent rate has been improved to almost 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17, 500 RMB. That's a price that few people will be able to afford.

But if the foldable device isn’t going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry expert told The Verge, “Few are debating if foldable mobile displays are the future of smartphones; the only question is when and by whom.”

1.What do we know about foldable devices?

A.They are too big to fit into the pocket.

B.They could bring us much convenience.

C.They have become available in January.

D.They are a burden to carry around without a bag.

2.What can we learn from Denison’s words?

A.The foldable screen has great potential.

B.The technology could change other devices too.

C.There must be many problems with the technology.

D.The production of foldable phones will soon decrease.

3.What does the underlined word in Paragraph 3 mean?

A.complete B.proper

C.imperfect D.normal

4.What can be a suitable title for the text?

A.Types of foldable phones.

B.The coming of foldable devices.

C.Popular devices on the market.

D.Difficulties in producing foldable phones.

Blue Planet II's latest episode(一集) focuses on how plastic is having a disastrous effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench，have plastic in their stomachs. Indeed, the oceans are drowning in plastic．

Though it seems now that the world couldn't possibly function without plastics， plastics used by consumers are a remarkably recent invention. The first plastic bags were introduced in the 1950s; the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science．

We put all these plastics into the environment and we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species，including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent．

And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning to the same degree as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers （否认者）, at least so far. To do something about it, we don't have to remake our planet energy system．

This is not a problem where we don't know what the solution is. We know how to pick up garbage．Anyone can do it．We know how to dispose （处理） of it. We know how to recycle. We can all start by thinking twice before we use plastic products. Things may seem ordinary, like using a reusable bottle or a reusable bag. But when taken collectively, these choices really do make a difference．

1.Why is plastics pollution research still a very early science?

A.The plastics pollution research is too difficult．

B.Plastics have produced less pollution than coal．

C.The world couldn't possibly function without plastics．

D.Plastics have gained in popularity too fast for science to catch up．

2.How did the author support his opinion in Paragraph 3?

A.By statistics．

B.By quotations from leading experts．

C.By using examples from his own experience．

D.By comparison and contrast．

3.What can we infer about climate change ?

A.Climate change is caused by human activities．

B.Climate change is not as simple as ocean pollution．

C.Climate change is less important than ocean pollution．

D.Ocean plastic is more complicated than climate change．

4.What is the main idea of this passage?

A.Ocean pollution is a global issue．

B.The oceans become choked with plastic．

C.Blue Planet II has left viewers heartbroken．

D.Plastics gain in popularity all over the world

Mickey Mouse and Shrek are just a couple of the American animated (动画的) characters loved the world over. And they are examples of the evolution of animation, which has brought unique new life to the film industry.

Among the first American animated films was Light of the Moon, a silent movie produced in 1911 using silhouette (剪影) animation, where the characters are represented only as black silhouettes.

The real breakthrough for American animation came with Steamboat Willie, created by Walt Disney and released in 1928. It was the first animated film to be accompanied by sound, and its main star, Mickey Mouse, became one of the most loveable and enduring animated characters ever created. Disney also created the first American full-length animated film, Snow White and the Seven Dwarfs. Released in 1937, it enjoyed worldwide box-office success.

Disney’s extremely careful attention to high-quality detail in the thousands of hand-painted drawings required at that time to make an animated film elevated this film technique to the level of a serious art form.

Clay animation is a type of stop-motion animation using forms made of clay. Clay animation films have been produced in the United States since 1908. But this form of animation only won wide popular appeal in 1955 with a short film called Gumbasia, created by Art Clokey.

Computer-generated imagery, or CGI, brought animation to a new level of artistry and realism. Used in film since the 1960s, CGI animation began to develop rapidly in the mid-1990s. Toy Story, released in 1995 and created by Pixar and Disney Studios, was the first completely computer-generated animated feature film.

In 2001, DreamWorks and Pacific Data Images released Shrek, the first computer-animated feature film to win an Oscar. Shrek returned in 2004 with his talking donkey, his princess bride Fiona and an army of fairy-tale characters in Shrek 2. Hugely popular, that film became the highest-grossing (票房最高的) animated film of all time.

In addition to strictly animated movies, animation has been mixed into films showing live actors as well. Who can forget the terrifyingly real dinosaurs thundering through Steven Spielberg’s Jurassic Park movies and the actors they chased? Thanks to the powerful capabilities of today’s computers and the unlimited imagination of American filmmakers, animation will be entertaining audiences worldwide for a long time to come.

1.The passage is mainly about the __________ of animation.

A.influence B.popularity

C.characters D.development

2.Which film marked the beginning of the complete digital age of American animation?

A.Light of the Moon. B.Steamboat Willie.

C.Toy Story. D.Shrek.

3.It can be learned from the passage that _______.

A.Jurassic Park movies involve only live actors

B.clay animation enjoys long-lasting popularity

C.computers make animated characters more lovely

D.Disney played a very important role in promoting animation

4.What can be inferred about the future of animation from the passage?

A.Animation will forever remain an essential form of entertainment.

B.Animation will be replaced by new forms of films in the near future.

C.Animation will continuously gain new life due to computers and imagination.

D.Animation will get more popular in the future for the developing film technology.
