Recently, I had found that some of our classmates study late into the night and do not take some time to take a rest during the day either. They often cannot help fall asleep in class. And some classmates seldom have breakfast, that is also a bad habit and will surely do harm to our health. In my opinion, it is extreme important for us to have enough sleep and a proper diet. We must learn to make a wise use of our time, and only in this way can we keep fit or study well. I wonder if you agree me. Thank you for listening.

Music is often targeted at teenagers. Because teenagers go through big changes and start making life-affecting decisions in their teens, people naturally wonder what effects music has on teenagers. Does it lead to violence? Help test scores? Teach them valuable lessons? 1. Music can help students improve academic performance. Studying music involves math and science, so students often improve in these areas. 2.According to a report, students who took part in music performance scored 41 points higher in math than those who did not take part in music performance. Being a teenager can be rough emotionally. Music is an especially emotional art form covering every type of emotion. 3. As music is a way to express emotions, many teenagers might try to make their own music, which can create healthy emotional expression. 4. Thus, listening to music can teach teenagers a lot about their own culture and other cultures. They can learn musical traditions, musical instruments, history lessons and more. Plus, as listening to music is a fun activity, this can often be a more interesting way to learn about a culture, rather than simply reading a textbook. Music tastes and interests can often bring people together, especially teenagers. 5. As well, music is often enjoyed at concerts and dance clubs where teenagers often hang out. Typically, the people attending these concerts and dance clubs already share a common interest, so a connection can be easily made. A. Music is often related with culture. B. This improvement can benefit them in tests. C. Music greatly improves teenagers,learning abilities. D. While there are negative effects, there are many positive effects, too. E. If they can find a song that matches their mood, they will feel comfortable. F. Rap music presents a new vocabulary teenagers won't learn in an English class G.Two teenagers who like the same style of music are easily to start up a friendship.
As a kid, Joanna Buckley wasn’t interested in science — until she had a chance to try it. That happened when she got a chemistry set for Christmas. “Over the course of a few weeks, I’d completed every experiment. But in the process, I polluted my parent’s dining room carpet and burnt the kitchen worktop with the spirit burner,” she says. Now science is Buckley’s job. She works in the chemistry department at the University of Sheffield in England. “I realize, first-hand, how important it is to have something or someone to show you why science is so great,” she says. Now the good news is that citizen science appears. Citizen science takes the fun of experimenting a step further than Buckley’s at-home chemistry kit. That’s because these experiments are real, looking for novel answers. “Compared with a one-off experiment, what’s cool about citizen science is that students get that this has a purpose,” Prunuske says. “Students want to do a good job, because they know scientists are going to use the new data in their own research.” Long agrees. “Kids like that it’s real. And they like that it’s important, that it matters.” Citizen-science projects have made big discoveries. One found a previously unknown galaxy cluster (星系团). Another project helped assess how much damage a big earthquake had caused in Japan. And one of the first citizen-science projects helped scientists learn where butterflies go every winter. Some adults worry about teens losing interest in science. That’s one reason they hope that fun, exciting citizen-science projects can help them keep in touch, Long says. And she has some evidence that it’s working, “Last year, we did have a couple of students say, ‘I really think I want to be a scientist now. ’” 1.What is the purpose of paragraph 2? A.To support trials can make teens interested in science. B.To prove failure is the mother of success in science. C.To state Buckley has a talent for science. D.To praise Buckley for her strong will. 2.Why is citizen science more fun? A.It carries out experiments frequently. B.It must carry out experiments in groups. C.It needs to seek for new solutions. D.It demands to handle complex problems. 3.What can we know from what Prunuske said? A.She participated in the experiment. B.She took pride in what students took up. C.Citizen science is popular with students. D.Scientists are willing to employ students. 4.What is Long’s attitude towards citizen science? A.Concerned. B.Supportive. C.Doubtful. D.Unclear.
It’s hard to be a bird in a world which is in the charge of mankind. You can hardly hear yourself sing, let alone hear the songs of your friends… and worst of all, you can’t hear a predator(捕食者). Noise is almost everywhere, especially noise from traffic. Researchers have tried to study the influence of road noise on animals by looking at animals living near noisy roads. “We figured out a way to have just the noise without any of the other effects of the road, and to do that we put many speakers in a forest where there was no road,” said Chris McClure, a biologist at Boise State University and The Peregrine Fund. He and his team carried out their experiment at a place popular with birds in Idaho as they fly south for the winter. While the noise kept lots of birds away, some remained. But they had trouble putting on enough weight to support them in the next part of their migratory journey. “They have to take food but they also have to avoid getting eaten by a predator. But these two things can’t be done at the same time because to eat, they have to look down, which means they aren’t looking at predators.” And when it’s too loud, they can’t hear the alarm calls of other birds. So they have to waste time looking for predators instead of searching for food. By 2050, it’s thought that enough new roads will be built to circle the planet more than 600 times. But there’s an easy solution to the noise problem—“Lowering speed limits does a lot.” So next time you’re driving through nature, just slow down a little. It’s safer for you and the wildlife. And you can enjoy the view a little longer. 1.Who does the word “you” in Para 2 refer to? A.A driver. B.A predator. C.A researcher. D.A bird. 2.Why did the researchers do the experiment in a forest without roads? A.To prevent birds from being hit by cars. B.To separate noise from other effects of the road. C.To test a larger number of birds. D.To put as many speakers as possible. 3.Why can’t birds put on enough weight with much noise around? A.They can’t concentrate on looking for food. B.They have to fly south for the winter. C.They can’t hear the alarm calls. D.They feel afraid of the noise. 4.What is advised to do to protect birds from the noise problem? A.To build enough new roads. B.To carry out more experiments. C.To enjoy the view a little longer. D.To drive slowly through nature.
“Cleverness is a gift while kindness is a choice. Gifts are easy – they’re given after all. Choices can be hard.” ---Jeff Bezos. I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I'd never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I'd been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn't work since most start-ups don't, and I wasn't sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor. I'd always wanted to be an inventor, and she wanted me to follow my passion. I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I admired very much. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said. “That sounds like a really good idea, but it would be an even better idea for someone who didn't already have a good job.” That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but eventually, I decided I had to give it a shot. I didn't think I'd regret trying and failing. And I suspected I would always be haunted by a decision not to try at all. After much consideration, I took the less safe path to follow my passion, and I’m proud of that choice. For all of us, in the end, we are our choices. 1.What inspired the author with the idea of building an online bookstore? A.His dream of being an inventor. B.Millions of exciting titles. C.The support of his wife. D.The greatly increasing usage of the Internet. 2.Which of the following is closest in meaning to the underlined sentence? A.He would be always feeling unsafe if he didn't try. B.He would be very excited if he tried it out. C.The idea of not trying would keep coming to his mind and disturb him. D.The decision not to build the online bookstore would terrify him. 3.What can we know from the text? A.The author appreciated his boss’s encouragement. B.The author might not regret if he failed the idea. C.The author might go back to his boss if he failed. D.The author wanted someone else to try the idea. 4.Which of the following would be the best title for the text? A.We Are What We Choose B.The Starting of Amazon C.Cleverness and Kindness D.Following My Passion

Nail biting and hair pulling are two forms of body language. Both nail biting and hair pulling can be either conscious or subconscious body language gestures, each showing some interesting aspects of the character, emotion and inner working of the individual. Nail biting is a non-verbal gesture. In adults it’s often a habit adopted and carried through from childhood and can become apparent in stressful situations throughout adulthood. To most people, nail biting is associated with nervousness and shyness and is an involuntary response to certain social situations. In many cases, it’s an adaptor behaviour that channels nervous energy, inactivity or boredom and doesn’t disturb normal functioning. In severe cases nail biting can become a repetitive behaviour that is intentionally performed. It can result in great physical damage. So when we look deeper, in both adults and children, it has been suggested that severe nail biting is often referred to as a method of “self-heating”. This indicates that nail biting is a subconscious behaviour indicating increased anxiety and low self-confidence. Hair pulling can indicate a number of emotions and behaviors. For example, children who bite their nails or frequently pull their hair may be nervous or have low self-confidence. Hair pulling may be a comforting action for a child who is tense and anxious, and may become habitual later in life in stressful situations. Routine and severe hair pulling can be a compulsive disorder that may be linked to genetics, anxiety and depression. It’s most commonly thought to be a stress-related condition. However, hair puling is also another non-verbal body language that can signify different things in different situations. For example, in some situations, it can mean interest and desire. However, in other situations, it can suggest anxiety, incompetence, uncertainty or shyness. 1.What does the text say about nail biting? A.It doesn’t harm its doer physically. B.It stops its doer functioning normally. C.It isn’t a gesture only made by children. D.It is a commonly used way to avoid shyness. 2.According to the text, children who often pull their hair . A.may take no interest in something B.may feel quite sure of themselves C.must suffer from lack of desire D.may not feel at ease at all 3.The underlined word “signify” in the last paragraph is closest in meaning to “ “. A.explain B.indicate C.hide D.summarize 4.What is the best title for the text? A.How to Read Forms of Body Language? B.What Do Nail Biting and Hair Pulling Suggest? C.How to Express Ourselves with Body Language? D.What Are the Deep Meanings of Body Language?
Scientists at the University of Oxford have developed new artificial intelligence (AI) software to recognize and follow up the faces of individual chimpanzees (黑猩猩) in the wild. The new software will allow researcher and wildlife conservationists to greatly cut back on time spent analyzing videos, according to the new paper published today in Science Advances. “For species like chimpanzees, which have complex social lives and live for many years, getting photos of their behavior from short-term field research can only tell us so much.” says Dan Sehofield, researcher and DPhil student at Oxford University’s Primate Models Lab, School of Anthropology. “By taking advantage of the power of machine learning to unlock large video files, it makes it possible to measure behavior over the long term.” The computers model was trained using over 10 million images (影像) from Kyoto University’s Primate Research Institute (PRI) video files of wild chimpanzees in Guinea, West Africa. The new software is the first to continuously track and recognize individuals in a wide range of posed, performing with high accuracy in difficult conditions such as low lighting and poor image quality. “Access to this large video file has allowed us to use the newest deep neural networks to train models at a scale that was previously not possible,” says Arsha Nagrani, co-author of the study and DPhil student at the Department of Engineering Science, University of Oxford. “Additionally, our new software differs from previous primate face recognition software in that it can be applied to raw videos with limited manual intervention (人工干预) or pre-processing, saving hours of time.” The technology has potential for many uses, such as monitoring species for conservation. Although the present application focused on chimpanzees, the software provided could be applied to other species, and help drive the adoption of AI systems to solve a range of problems in the wildlife sciences. 1.What’s the purpose of developing the new software? A.To save wildlife researchers’ time spent in the wild. B.To keep track of wildlife conservationists’ behavior. C.To protect chimpanzees and help them to live longer.

It’s not every day that you see pigeons(鸽子)with cowboy hats on their tiny heads walking or flying around, unless you live in Las Vegas, where cowboy-hat-wearing pigeons are actually a thing people have been constantly taking about these days. It all started on December 5, when a Las Vegas citizen named Bobby Lee noticed two funny-looking birds walking near a dustbin. The pigeons drew his attention because they were wearing tiny cowboy hats — one red and one grey — so he took out his smartphone and started filming them. Later, he uploaded the video online, where is quickly spread. The next day, everyone was talking about Las Vegas’ cowboy-hat-wearing pigeons, and Lee was getting phone calls from agencies trying to license his video. It was only a matter of time before news outlets picked up the story and reported on the mysterious pigeon cowboys spotted around Las Vegas. The only link anyone could think of was the Wrangler National Rodeo Finals that were taking place in town at the time, but the Professional Rodeo Cowboys Association, which organized the event, denied any involvement. While some netizens just found the idea cute and jumped at the opportunity to catch the pigeons on camera if they spotted them around Vegas, others expressed concern about the birds’ well-being. They even mentioned animal cruelty. Hillman, the founder of local pigeon rescue Lofty Hopes, said that her organization was trying to track down the birds and remove their hats, but trapping them with food has proven very difficult so far. That’s because the two known cowboy-hat-wearing pigeons have become very popular around Las Vegas, and people are constantly throwing them much food. “When you see them today, you could see some loose feathers in the glue around the hat, and it’s surely a concern,” Hillman said, adding that she believed the hats had been glued on with a strong adhesive (粘合剂). 1.What has been a hot topic in Las Vegas recently? A.The return of cowboy hats. B.Pigeons approaching people. C.Pigeons wearing cowboy hats. D.The hobby of watching pigeons. 2.What made Bobby Lee film the two pigeons with his smartphone? A.Their unusual decorations. B.Their unique feather colors. C.Their great popularity online. D.Their strange way of walking. 3.What was netizens’ attitude towards the pigeon cowboys? A.They went too far about them. B.They thought nothing of them. C.They showed little interest in them. D.They had a mixed response to them. 4.Why is it hard to trap the two pigeons with food? A.Because they are rather particular about food. B.Because they always have abundant food to eat. C.Because they are smart enough not to be tricked. D.Because they are well protected by pigeon watchers.
