期末加油呀UNIT 3Unit testA C A C BB B D A CC BD D DIn the town where I grew up, there were two creeks running through it. In the 1) winter, I'd trap muskrats, and we also skated a lot. Rocky Fork Creek ran a great distance, and we'd 2) literally skate for miles. Big Walnut Creek on the other hand was where more folks from the 3) community came to skate socially. It was a much 4) wider creek. We'd have bonfires there and had some great hockey games, too.My friend, Zeke, had 6 5) siblings and every kid in the family had their own horse, so we'd go to Zeke's and ride through the 6) woods and meadows. Zeke would pull us on sleds using his dad's tractor. In the summer, we'd 7) explore the creeks, and I'd be 8) catching snakes and frogs, and fishing.In the summer my family and I traveled to Butler, PA to visit my grandparents. We would play golf or at night we all played cards. Grandpa would take me fishing and he and I 9) would run errands all around town in his red old car. On Friday nights he and I watched the Gillette Fights.My family and I also spent two weeks each summer at Conneaut Lake Park. There was a huge three-story hotel whose grounds were really beautiful. The park also had a small 10) golf course, and a midway, and I recall we could ride all the rides in the amusement park for only $2 on Wednesdays. I'd get up and go fishing in a nearby canal before the rest of the family awoke.UNIT 4ConversationsD B C A DB C D BPassagesB C A DScientific research should improve our overall quality of life. The government should provide financial and political support to any research that is likely to result in immediate and significant benefits for the people. However, people's ideas 1)vary when it comes to whether the government should support scientific research with no practical use. Still 2) a large portion of people believe that the government should distribute adequate funds to any scientific research that aims to improve the 3)well-being of people, even if it is of no practical use in the short run.Scientific research whose social benefits are immediate, predictable, and 4)profound should continue to be a high priority. For example, biotechnology research has beenproven to help cure and prevent diseases; information technology enables education to be more 5) accessible; and communication technology facilitates global peace by improving mutual understanding among people and their participation in the democratic process.However, this is not to say that research whose benefits are less immediate or clear should be given a lower priority. It is difficult to predict which research will 6)ultimately lead to the greatest contributions to society. Reluctance to finance less practical scientific research could 7)have a harmful effect on the efforts to explore new knowledge. This is particularly true of the computer sciences. For instance, before the first computer was invented, public opinions 8)went against it, as most people saw nothing practical in computer research. However, computers transformed the way human society evolved and proved to be of great avail in the long run, especially in terms of scientific development in fields such as the military, medicine, 9)aviation, and education.Therefore, never should we think that scientific research whose benefits are unknown 10)is not worth pursuing since the purpose of any research should be to discover truths, whatever it might be.Unit testB C A C DC CD A DD A B A AThis might be an important scientific breakthrough. A scientist set out to improve the productivity (生产力) of farm animals and along the way set off a 1) biological earthquake. The experiment he 2) firmly pursued (从事) involved work with a cell from an adult mammal. His 3) efforts were to make a cell behave like a cell from a developing embryo (胚胎). And it was successful. He and his coworkers cloned a sheep called Dolly and introduced her to a skeptical world in February 1997.Perhaps it was his 4) isolation in a quiet rural part of Scotland that permitted him to resist the 5) objectors. Or perhaps it was the isolation of the remote field of farm animals that gave him the 6) originality. However, he seemed as surprised as anyone else that his 7) modest and simple experiment should have a great impact on oursense of what it is to be human. He wanted to use his cloning technology to 8) improve the health, the quality, and the productivity of farm animals. Any experiment with humans, he believed, should always be kept strictly at the very low level of cells and proteins. It would be 9) morally unacceptable, he said, to use his technique to create a human clone. Of course, this achievement would bring fear, debate and new 10) legislation in countries around the world. In a word, Dolly the sheep has changed the world.UNIT 5ListeningUse the skills 2.31.And I've always (1)loved fashion, so the idea that I could go to fashion shows in Paris, New York, etc. was just (2) amazing for me.What I didn't realize is that actually being a model is really, really(3)hard work.2.And the problem is that you need to (1)look good all the time. But often, you're (2feeling terrible).3.I could spend my days sitting in some of the best restaurants, (1)eating delicious food, and (2)get paid for it. The only problem, which I didn't realize at the time, is that actually you can (3) get bored of eating restaurant food.4.I used to spend hours in the gym, doing exercise to try and (1)workoff the food I was eating. But it was impossible. So, in the end, (2)I gave it up.5. I had this (1) (wonderfully romantic) idea of owning my own vineyard,making wine, and spending my life in the beautiful Tuscan countryside.But the reality is very different. I had no idea (2) (how tiring) the job would be.6. And in September, a bad storm can (1) (ruin the grapes) in just a fewminutes. At least when I worked in an office, I didn't use to (2) worry about the weather. Having said that, I love my life. And the science of making wine is (3)worry about the weather.More practice in listeningConversationsB B A D CB A B DPassagesD A B DA poorly trained manager can make an employee's life miserable. In 99 out of 100 cases, employees may 1) suffer from low spirits and then gradually become no longer 2) enthusiastic about their jobs just because they have a boss who doesn't approve of them, doesn't listen to them, or generally 3) erodes their self-esteem.Three basic skills that every manager should use in order to be 4) competent on the job are: being specific, enhancing others' self-esteem and listening effectively. Being specific means giving 5) clear-cut instructions about what is to be done and the results to be achieved. Being specific also means describing the behavior of people rather than 6) labeling people. It includes giving both positive feedback that tells them what to repeat and corrective feedback that is firm, yet not critical. Then it 7) comes down to evoking in the employees self-esteem. Self-esteem is a private, individual matter. It is not fixed, but goes up and down from day to day, or even from hour to hour. Thus, building self-esteem is no easy task. Managers can't MAKE people feel good about themselves, but rather, they need to help people develop their own self-esteem as self-esteem is like a door that's locked from the inside. A final skill that today's managers need more than ever is listening. Listening may seem like a 8) commonplace skill, but it's not practiced as much as it should be in business today. People 9) tend to think about what they are going to say in response when another person is talking, instead of 10) focusing on what that person is saying and what he / she means.Unit testA C AB BD C A B BA C A A DDo you happen to know something about the police? In police work, you can never 1) predict the next crime or problem. No working day is 2) identical to any other. So there is no "3) typical" day for a police officer. Some days are relatively slow, and the job is 4) boring; other days are so busy that there is no time to eat. I think I can describe police work in one word: 5) variety. Sometimes it's 6) dangerous. One day, for example, I was working on a special assignment; that is, I was on the job, but I was wearing 7) normal clothes, not my police uniform. I was trying to catch8) some robbers who were stealing from people as they walked down the street. Suddenly, seven bad men jumped out at me; one of them had a knife, and we got into a fight. Another policeman arrived, and the two of us 9) captured three of the men; but the other four ran away. Another day, I helped a woman who was going to have a baby. She was trying to get to the hospital, but there was a bad traffic jam. I put her in my police car to get her there faster. I thought she was going to have the baby 10) right there in my car. But fortunately, the baby waited to "arrive" until we got to the hospital.UNIT 6ConversationsC A B A BA C C BPassagesA DB BThe Sultana was a Mississippi River steamboat destroyed in an explosion on April 27, 1865. An 1) estimated 1,800 of the 2,400 passengers were killed, and the Sultana sank not far from Memphis, Tennessee. This disaster received little public attention, as it took place soon after the President Abraham Lincoln was 2) assassinated.The wooden steamboat was constructed in 1863 and 3) was intended to be used for the lower Mississippi cotton trade. Registering 1,719 tons, the steamboat was built to carry no more than 365 people. For two years, it ran a regular route between St. Louis and New Orleans. Sometimes it was asked to carry troops.The Sultana left New Orleans on April 21, 1865. Most of the passengers were Union soldiers who had recently been 4) released from Confederate prison camps. The US government had 5) made a contract with the Sultana to transport these former prisoners of war back to their homes in the north.At 2 a.m. on April 27, about seven miles north of Memphis, at least one boiler 6) gave way, causing a huge explosion that destroyed the center portion of the boat, throwing sleeping men high into the air before landing in the river. Confusion and chaos 7) ensued as men tried to save themselves and others. Many drowned while others burned to death.The direct cause of the explosion was later determined to be the leaky and poorly repaired steam boiler. Passengers who 8) survived the initial explosion had to risk their lives in the icy water of the Mississippi or burn with the ship. Many died of drowning or coldness. Bodies of 9) victims continued to be found downriver for months. Many were never recovered. Some of the Sultana's crew, including the captain, were among those who 10) perished.Unit testC B A C DC CD A BC AD C DIn the middle of the eighteenth century, France and Britain clashed in a conflict that has come to be known as the French and Indian War. French and Indian soldiers, sensing their mutually 1) beneficial situation in the American frontier, pulled together. And they 2) fought against British forces. But the powerful British Empire briefly 3) strengthened its hand in North America with victory in this struggle. The French slowly 4) pulled out of North America. The British, for their 5) part, determined to hand over a great piece of land. They decided that the territory west of the Allegheny Mountains and north of the Ohio River should 6) serve as a large Indian settlement closed to general settlement by English colonists.By 1783 the American Revolution had produced an 7) amazing change of fortune in North America. The United States of America 8) stood as a new nation while British soldiers retreated to the northwest (today's Michigan and Ohio).Americans eyed these lands, which the British had 9) sought to give away to the Indians in the area. As Americans moved westward into the new frontier, they replaced the French and Indian "middle ground" social agreements with a system of law emphasizing private property, farming, and eventually industrial development.Cultural ideals that promoted Christian 10) civilization, marked Indians as animals, and created a firm distinction in sex roles in this new system.UNIT 7ConversationsC A BD BD A B DPassagesB A A CResearch shows a close relation between reading speed and understanding that in most cases an increase in rate 1) was accompanied by an increase in comprehension and a decrease in rate brought decreased comprehension with it. However, simply speeding the rate especially through forced 2) acceleration may actually result in making the real reading problem more 3) severe. The obvious solution, then, is to increase rate as a part of a total 4) endeavor / endeavour of the whole reading process. Then how?You can prepare for maximum increase in rate by establishing 5) practicable habits, such as avoiding rereading and whispering while reading, learning to adjust reading rate to increase comprehension.Rate adjustment may be overall adjustment, or internal adjustment within an article. As an 6) analogy, imagine that you plan to take a 100-mile mountain trip in three hours, averaging about 35 miles an hour. This is your overall rate adjustment. However, in actual driving you may slow down to 15 miles per hour on some curves, while 7) speeding up to 50 miles per hour on relatively straight sections. This is your internal rate adjustment.Poor results are inevitable if the reader 8) attempts use the same rate for all types of material and for all reading purposes. A good reader adjusts his / her reading rate from article to article, or even within a given article. So you need to 9) foster a good reading habit by daily training until a flexible reading rate becomes 10) second nature to you.Unit testB A AC AD D C A BC C B A AThe first step in stopping drug use is learning why people start using drugs. The reasons people use drugs are as 1) different as people are from one another. But there seems to be one common 2) thread: people seem to take drugs to change the way they feel. They want to feel better or feel happy or to feel 3) nothing. Sometimes, they want to forget or to remember. People often feel better about themselves when they are under the influence of drugs. But the 4) effects don't last long. Drugs don't 5) solve problems. They just hide them. No matter how far drugs may take you, it's always a 6) round trip. After a while, people who miss drugs may feel 7) worse about themselves, and then they may use more drugs. If someone you know is using drugs, you can help. You can let your friends know that you care. You can listen and 8) try to solve the problem behind your friend's need to use drugs. Two people together can often solve a problem that seems too big for one person alone. Therefore, the most important 9) part that you can play is to be there. Studies of heavy users in the United States show that they felt unloved and unwanted. They didn't have close friends to talk to. When you or your friends 10) take the time to care for each other, you're all helping to stop drugs abuse. After all, what is a friend for?UNIT 8ConversationsA C D A AD B C DPassagesA C C DThe most useful bit of the media is disappearing. In North America, newspapers are now an 1) endangered species. The business of selling words to readers and selling readers to advertisers, which has sustained their role in society, is 2) falling apart.Of all the old media, newspapers have the most to lose from the Internet. Circulation has been falling in many countries. But in the past few years the Web has hastened the decline. In his book The Vanishing Newspaper, Philip Meyer 3) calculates that the first quarter of 2043 will be the moment when newsprint dies in America as the last exhausted reader 4) tosses aside the last crumpled (弄皱的) edition.Advertising is following readers who 5) turn to the Internet. The rush is intense, largely because the Internet is an attractive medium that 6) unprecedentedly matches buyers with sellers and proves to advertisers that their money is well spent. In Switzerland and the Netherlands newspapers have lost half their 7) classified advertising to the Internet.Newspapers have not yet started to 8) shut down in large numbers, but it is only a matter of time. Over the next few decades half of North America's general papers may fold.Jobs are already disappearing. According to the Newspaper Association of America, the number of people employed in the newspaper industry fell by 9) approximately 18 percent between 1990 and 2004. Moreover, this year Morgan Stanley, an investment bank, attacked the New York Times Company, because its share price had fallen by nearly 50 percent in four years. This may suggest, to some extent, that tumbling shares of listed newspaper firms have prompted 10) fury from investors.Unit testA AB D CB DC C AB C A D CFor many of us, communicating used to mean sending letters and cards through the mail and getting no response until weeks later. We'd pass 1) hand-written notes to friends in class. We'd pick up the telephone —paying for 2) long-distance calls — and could only talk to one person at a time. On top of that, there were no 3) answering machines to leave messages if a person wasn't home, or Caller ID to 4) screen calls if we didn't feel like picking up the phone. And pay phones were the only 5) option to call home if our car broke down on the side of the road, or if we had to stay after school. For the past decade or so, technology has 6) transformed the way we communicate, in part due to the use of the Internet. Instead of 7) mailing letters, we're writing e-mails through Gmail or Windows Live Hotmail that can be sent 8) instantly to the recipient (接受者). We can even add multiple recipients to these e-mails, so that more than one person can read them. Even more, we can send greeting cards over the Web. And no postage is needed! Sending a note to a friend can be done 9) in a matter of seconds. We are no longer bound tolong-distance charges, either. Mobile phones have become a 10) god-send gift, letting us place calls no matter where we are. And text messaging has become an efficient way to get a short message across, such as "Meet you there at 8" or "I'll be home late."。
