As the world's resources become rarer because of continuing land development and the growing human population, the natural habitats of wild animals have continued to decrease. As a result, the survival of some species of wildlife is threatened. To help protect wildlife, a lot of practices should be carried out by environmentalist as well as the general public. Create homes for species that are endangered because of losing their own natural habitats. Wildlife shelters should be developed, and habitats should be created in existing(现存的) national parks. Efforts(努力) should also be made to protect existing habits, such as providing food and water sources and limiting hunting. Breed(培育) endangered species in places such as zoos. Once the young animals grow up, they can be set free into the wild where they can continue to increase the population. The general public may not realize that a species is endangered until it's too late. Educational programs making use of TV advertising and instructional meetings at national parks can be used to make the public know the situation. The general public can help protect the wildlife by not hunting wild animals for sport or for a source of food. They should also stop supporting those who earn money from the illegal hunting of wild animals, such as hunters who kill animals for the only purpose of harvesting their body parts and selling them for money. The public should avoid(避免) keeping wild animals as pets. This will limit the number of animals being tracked, trapped, sold and removed from their natural habitat. 1.Which of the following is not the measure of protecting animal habitats? A.Developing wildlife shelters. B.Creating new habitats. C.Setting young animals free in the wild. D.Protecting the existing habitats. 2.The underlined words "the situation" in Paragraph3 probably refer to the fact that ______. A.the general public may not know species are endangered. B.many endangered species are facing the danger of extinction. C.people can do much to protect the endangered species. D.human activities can affect the existence of species. 3.We can learn from the passage that _______. A.some people hunt animals and sell them as pets B.hunters get little money from hunting animals C.general public do nothing about protecting the wildlife now D.animal population becomes larger in the zoo 4.In which column(栏) of a newspaper can we read the passage? A.Environment. B.Sports. C.Technology. D.Education.
Shortly after the war，my brother and I were invited to spend a few days with an uncle who had just returned from abroad. He had rented a cottage in the country，although he rarely spent much time there. We understood the reason for this after our arrival: the cottage had no comfortable furniture（家具）in it；many of the windows were broken and the roof leaked（渗漏），making the whole house terrible. On our first evening，we sat around the fire after supper listening to the stories which our uncle had to tell of his many adventures in distant countries. I was so tired after the long train journey that I would have preferred to go to bed；but I could not stand missing any of my uncle's exciting stories. He was just in the middle of describing a rather terrifying experience he had once had when there was a loud crash from the bedroom above，the one where my brother and I were going to sleep. "It sounds as if the roof has fallen in！"cried out my uncle，with a loud laugh. When we got to the top of the stairs and opened the bedroom door，we could see nothing at first because of the thick clouds of dust which filled the room. When the dust began to clear，a strange sight met our eyes. A large part of the ceiling had fallen down，falling right onto the pillow（枕头）on my bed. I was glad that I had stayed up late to listen to my uncle's stories，otherwise I should certainly have been seriously injured，perhaps killed. That night we all slept on the floor in the sitting room downstairs，not wishing to risk our lives by sleeping under a roof which might at any moment fall down on our heads. We left for London the very next morning and my uncle gave up his cottage in the country. This was not the kind of adventure he cared for either！ 1.Why did the uncle seldom spend much time in the country cottage？ A.Because the roof of the cottage had fallen. B.Because the cottage was in bad condition. C.Because he was used to living abroad. D.Because the rooms were too small to live in. 2.When the author and his brother opened the bedroom door，they could see nothing at first because. A.it was completely dark inside B.there was too much dust in the air C.something strange stopped them D.it was a mess inside 3.The author felt glad that he had stayed up late because. A.he did not miss the exciting stories B.he spent more time with his uncle C.he had a lucky escape D.he saw a strange sight 4.Which of the following can best describe the writer's uncle？ A.Adventurous and good at storytelling. B.Humorous and good at making jokes. C.Dependable and generous with money. D.Thoughtful and sensitive to danger.

Did you know that the color of uniforms can influence the performance of an athlete? It may sound strange, but a study suggests this might be true. Two British scientists studied the results of four sports in the 2004 Athens Olympic Games where the athletes had been given either a red or a blue uniform. They discovered that when there was a big difference in the score, color had no influence on the result. But if it was a close match, the athlete in a red uniform was more likely to win. Then they looked at the uniforms of the soccer teams at the Euro 2004 tournament. Again, teams wearing red won more games. The two scientists got their idea from earlier studies of wild animals. It had been discovered that when a male show red on its body, it sends a signal of its power and strength. For example, in many kinds of monkey, the more the male shows off its red scare, the more females it can attract Based on this fact, the British scientists thought that the idea might work for humans, too. According to them, when an athlete sees a competitor in a red uniform, he gets a feeling that his competitor could be stronger than him. And that kind of feeling may have a bad influence on the player’s performance in the actual game. Although the idea is Interesting, most people don’t accept that color signals in the animals world can really be useful to humans in sports. They think that it is unreasonable to develop an Idea based on such a small number of examples. Much more research has to be done to prove the influence of uniform colors on the performance of athletes. 1.What did the scientists find out about the 2004 Athens Olympic Games? A.Athletes played equally well in four sports. B.Game results had a big influence on the athletes. C.Athletes dressed in red scored more in a close match. D.There was a big difference in read and blue team’s scores. 2.What may the red scars of a male animal suggest? A.It is quite strong. B.It is a failure. C.It has power over other males. D.It has attracted a lot of females. 3.The underlined part “that kind of feeling” in the text refers to a feeling of . A.weakness B.pride C.danger D.shame 4.what is most people’s opinion to the scientists’ idea? A.Interested B.Satisfied. C.Doubtful. D.Thankful
During ancient times, children didn’t have smartphones, iPad or computers to entertain themselves. Instead, they came up with interesting games to play. ★ Stone balls During the Qing Dynasty, kicking a stone ball around was a popular sport in the northern part of China, and it was often played in the winter to protect kids from the cold. Stones were carved into small balls and kicked along with feet. In 1999, the sport was included in the 6th National Ethnic Group Traditional Sports Meeting held in Beijing. ★ Flying kites Kites have quite a long history. The earliest kites were made of wood, instead of paper. Nowadays, the four most famous kites are the Beijing kite, Tianjin kite , Weifang kite and Nantong kite, of which each has distinctive features. The kite which resembles a swallow is a well-known Beijing style. ★ Hide-and-seek Hide-and-seek is a traditional game for children, popular around the nation. There are two ways to play: covering a child’s eyes while other kids run around to tease(戏弄) him or, more commonly, participants hide and one child must try to find them. ★ Playing diabolos A diabolo is always made of wood or bamboo and has empty space in the center. By juggling(边抛边接) the diabolo on the rope, the high-speed spinning diabolos will make a sound like a whistle. Playing diabolos is an interesting folk game, especially popular in North China. Playing diabolos was also included in the first group of national intangible cultural heritage(非物质文化遗产). 1.Why did ancient children often play stone balls in the winter? A. To practice their feet. B.

When Albert Einstein was young, he was a quiet child who spent much of his time alone. He was slow to talk and had difficulty in learning to read. When Albert was five years old, his father gave him a compass. Albert was filled with wonder when he discovered that the compass needle always pointed in the same direction ---- the north. He asked his father and his uncle what caused the needle to move. Their answers were difficult for Albert to understand. Yet he spent a lot of time thinking about them. He said later that he felt something must be hidden behind things. Albert didn’t like school. The German schools of that time were not pleasant. Students couldn’t ask questions. Albert said he felt as if he were in prison.. One day Albert told his uncle Jacob how much he hated school, especially mathematics. His uncle told him to solve mathematical problems by pretending to be a policeman. “You are looking for someone,” he said, “but you don’t know who he is. Call him X. Find him by using your mathematical tools.” Albert learned to love mathematics. He was studying thecomplexmathematics of calculus while all his friends were still studying simple mathematics. Instead of playing with his friends he thought about things such as “What would happen if people could travel at the speed of his light?” Albert wanted to teach mathematics and physics. He graduated with honors, but it was a pity that he could not get a teaching job. 1.According to Paragraph 2, we can learn that Albert Einstein ________.

Learning to understand spoken English can be difficult. Learners must not only master new sounds, but also learn conversational idioms. That's a let to learn! But they may soon realize there is something else going on. 1. These different styles of speaking are called "registers". In their work, language experts identify three major factors that affect the register of spoken English: the place of the conversation, the relationship of the speakers, and the purpose of the conversation. 2. Even two best friends who work and live together may speak more formally to each other in the office. At home, one might say, "C'mon, I wanna leave." The same person at work might say, "Are you ready to go now?" The relationship of the speakers also affects the language they use with each other. People speak less formally to friends and more formally to strangers. 3. People who know each other well might use more idioms and more slang in their speech. An angry woman might tell her daughter to "hush your mouth" and her sister to "quiet down". Finally, the purpose of the conversation affects people's speech. A person who want to ease hurt feelings uses a soft, quiet tone. 4. Few speakers realize that they change registers according to these factors. 5. We are not aware that we make these changes. We accept the changeability of the weather, but we often refuse to accept the changeability of speech. A. In fact, most people strongly deny it. B. People generally speak less at work than they do at home. C. The very same person speaks differently in different situations. D. Therefore, we should be careful not to hurt each other with our speech. E. On the other hand, a person who wants to pick a fight speaks rapidly and loudly. F. The place where the conversation takes place directly affects the language of the conversation G. Because they already share information and experience with friends, they do not need to explain as much.
How affordable is high culture? One great myth of our time is that tickets for opera, theatre, ballet and orchestral (管弦乐) concerts are too expensive, especially for the young. This is infuriating as, in Britain, at least, the claim is ridiculous and offensive. The cheap tickets to hear London's orchestras range from ￡7 to ￡9 — same as a cinema ticket, and lower than the entry price to many pop music and comedy clubs. For comparison, when the Los Angeles Philharmonic Orchestra performs with top soloists and conductors the cheapest seat is ￡30; and at the Berlin Philharmonic, it's an expensive ￡46. Finding cheap tickets to the opera and ballet isn't so easy. True. British companies don't charge the ridiculous high prices found on the Continent (￡2,000 for a good seat at a premiere of La Scala's Carmen last December), but the tickets are still pretty steep. Large fees paid to star performers mostly account for that. Luckily, however, one spectacular technological innovation has transformed the scene. It's live (or slightly delayed) cinema transmissions. The New York Metropolitan Opera now beams its shows to 800 cinemas round the world, and British companies aren't far behind. Cinematic opera is excellent value. For the cost of a good bottle of wine (￡10 or ￡15 for the Royal Opera House's shows) you can sit in your local movie-house and see a high-definition relay of what's occurring on the world's grandest stages. No, it's not the same as being there, but it's almost as good. The sound is incredible. The images, particularly of dancers, are fantastic. And you can react to the show as part of a live audience, rather than sitting on your own at home. To me, this mountain of evidence, together with free museum admissions, indicates that the arts world should stop worrying that its audiences are still mostly middle-class. Anyone who can afford to visit a pub can also afford to see top-quality drama, music and dance. The real battle now should be ensuring that school children are given enough tastes of high culture to make them want to buy all those cheap tickets when they grow up. 1.What does the underlined word "infuriating" in paragraph 1 mean? A.Quite interesting. B.Very annoying. C.Not certain. D.Extremely obvious. 2.What is the main reason for expensive opera tickets? A.The amount of money charged by top performers. B.The costly technology required for broadcast. C.The demand of companies for big profits. D.The high cost of renting the stages. 3.Which of the following is true about cinematic opera? A.People can decide where to watch the opera. B.Audiences are discouraged from responding to The performances. C.It provides an inexpensive way of enjoying a live opera performance. D.The sound and visual quality are superior to the live performance. 4.Which statement would the author agree with? A.The quality of opera performances is improving. B.High culture is becoming more affordable in Europe. C.The cost of access to high culture activities should be lowered. D.Children should be encouraged to participate in high culture events.
Sleep, considered a luxury by many, is essential for a person's wellbeing. Researchers have found that insufficient sleep and tiredness increase a person's risk of developing severe medical conditions, such as obesity (being very overweight), high blood sugar levels, and heart disease. Now, a new study has found that getting sufficient sleep is also the key to improving academic performance. Jeffrey Gross, the university science professor who led the research, was not trying to find the relationship between sleep and grades when he handed out smart watches to the 100 students in his chemistry class. Instead, the professor hoped the wrist-worm devices, which track a person's physical activity, would show a connection between exercise and academic achievement. While Gross's data showed no relationship between these two factors, the study found something surprising. As the researchers were analyzing their data, they noticed that there was a straight-line relationship between the average amount of sleep a student got and their results in the course's 11 quizzes, three midterm tests, and the final exam. Even more interesting, it was not sufficient for students to just head to bed early the night before a test. Instead, it's the sleep you get during the days when learning is happening that matters most. The time students went to bed each night was similarly important. Those who went to bed in early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student. "When you go to bed matters," Gross says, "If you go to bed at 10, or 12, or 1 at night, and sleep for seven hours, your performance is the same. But if you go to bed after 2, your performance starts to go down even if you get the same seven hours. So, quantity isn't everything." Perhaps the most interesting was the huge impact that small differences in sleep patterns had on the students' grades. The overall course grades for students averaging six and a half hours of sleep each night were 25% lower than students who averaged just one hour more sleep. Similarly, students who varied their bedtime by even one hour each night had grades that dropped 45% below those with more regular bedtimes. Who knew getting A's just required some extra ZZZ's? 1.Based on his original objectives, which best describes Professor Gross's research findings? A.Accidental. B.Complete. C.Convincing. D.Doubtful. 2.Who were the people taking part in the study? A.Middle school chemistry students. B.Volunteers from different universities. C.Professor Gross's own students. D.University student athletes. 3.How did Professor Gross's team measure academic performance? A.Making the students wear a special watch. B.Using students' university entrance test results. C.Giving the students regular after class quizzes. D.Using the students' normal test and quiz grades. 4.Based on the study's findings, who is likely to perform best academically. A.A person who has a good night's sleep the night before an important test. B.A person whose normal bedtime varies between 9 p.m. and 12 p.m. C.A person who sleeps from 11 p.m. to 6 a.m. each day. D.A person who sleeps for a total of 7 hours each night.
