Everybody hates rats(老鼠). But in the earthquake capitals of the world—Japan, Los Angeles, Turkey—rats will soon be man’s new best friends.
What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal(信號). This is sent to a small radio on its back and then the rescuers follow the radio signals. When rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “Robots’ noses don’t work well when there are other smells around. Rats are good at that. ” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to, and a rat would get out if it wasn’t safe. ” Perhaps for the first time in history, people will be happy to see a rat in a building, but only after an earthquake, of course.
【小題1】 In the world earthquake capitals, rats will become man’s best friends because they can ______.

A.take the place of man’s rescue jobs
B.find the position of people alive who are trapped in buildings
C.serve as food for people alive who are trapped in buildings
D.get into small spaces
【小題2】From the third paragraph we know the rescuers can judge a person is alive by ______.
A.the noise made by the rat
B.the rat’s unusual behavior
C.the signal sent by the radio on the rat’s back
D.the smell given off by the person
【小題3】In doing rescue jobs, ______.
A.rats smell better than dogs
B.dogs don’t need to be trained to smell people
C.robots’ sense of smell can be affected by other smells around
D.rats can see in the dark and they are smaller than robots
【小題4】Rats have all the following advantages EXCEPT that ______.
A.they are more fantastic than other animals
B.they are less expensive to train than dogs
C.they don’t need electricity
D.they are small and can get into small places


【小題1】B
【小題2】C
【小題3】C
【小題4】A

解析試題分析:
【小題1】B 推理題。根據文章第2段. So now a new research project is using a smaller animal to save lives: the rat.和第三段說明人們可以利用老鼠來找到那些被圍困在地下的人,并把他們救出來。故B正確。
【小題2】C 細節題。根據第三段1,2,行When this happens, the rat’s brain gives a signal(信號). This is sent to a small radio on its back and then the rescuers follow the radio signals.說明研究人員可以根據這些信號來辨別這個人是否是活著的。故C正確。
【小題3】C 細節題。根據第四段第二行“Robots’ noses don’t work well when there are other smells around.說明機器人的嗅覺是人員被干擾,故C正確。
【小題4】A 細節題。根據文章第二段第二行But dogs are big and they can’t get into small spaces.說明老鼠可以到更小的地方,故D是老鼠的優勢;根據第四段第三行They are cheaper and quicker to train than dogs,說明B是優勢。根據第四段最后一行they don’t need electricity!說明C也是老鼠的優勢。A沒有提及。故A不是老鼠的優勢。

科目:高中英語 來源:2013屆浙江省臺州中學高三第一次統練英語試卷(帶解析) 題型:閱讀理解

Water, which covers about 74 percent of the earth’s surface, is man’s most precious resource. Without it we cannot live. Clean water keeps us alive; polluted water means disease and death.Keeping our water pure is by no means an easy task but it is something that must be done.
Hong Kong once prided herself on being the “Fragrant Harbour”. However, these days, it is not certain if Hong Kong’s harbour could still be called “fragrant”. For, like many other places, Hong Kong has not been spared water pollution. A visit to Tolo and Victoria Harbour, or any of the beaches in Hong Kong is enough to make one aware of the ugly truth that Hong Kong waters are indeed polluted.
The great threat to our water is bacteria pollution. Another great source of water pollution is poisonous chemicals. These substances, which are found in industrial waste and agricultural pesticides, make up unseen dangers that enter biological food chains.
Pollution control is a continuing problem for the government. It is believed that the most effective form of control is legislation(立法). Most importantly, the present laws on pollution should be given more force. On the other hand, no amount of legislation can effectively control pollution unless those concerned are properly educated about the danger posed by pollution.
While a great majority of Hong Kong citizens and residents seem to be greatly concerned about ways to control water pollution, it is discouraging to note that there are, in our midst, some people who remain apathetic(無動于衷)about the problem. In a recent radio programme conducted on what people in the streets thought about the water pollution problem, one apparently unconcerned person said, “What do I care about water pollution? I don’t drink polluted water. As long as the water I drink is not polluted, I’m not bothered. Water pollution is too big a problem and let’s leave it to the government.”
If all residents in Hong Kong will take such an indifferent attitude, all the government’s attempts to control pollution, let alone the anti-pollution legislation, will prove useless. The best form of pollution control each citizen can employ is to be aware of his surroundings. We hope that someday, the problem of water pollution in Hong Kong will cease to alarm us.
【小題1】By the underlined sentences, the writer wants to show that ______.

A.we should not use polluted water
B.it is our responsibility to keep our water clean and safe
C.clean water is vitally important to the survival of human beings
D.water is abundant but very expensive
【小題2】What can you infer from the second paragraph?
A.Hong Kong indeed deserves the name.
B.Hong Kong never deserves such a name.
C.Hong Kong can’t avoid the damage of pollution.
D.Hong Kong has failed to live up to such reputation.
【小題3】The writer quotes the words in the programme to show us that a block to the solution of the problem is _________.
A.people’s lack of education
B.people’s I-don’t-care attitude
C.people’s wait-and-see attitude
D.people’s over-dependence on the government
【小題4】In the final analysis, the best approach to the problem of water pollution is ________.
A.legislation
B.rapid development of modern science
C.mass education
D.everybody taking care of his own surroundings

Fifteen years ago, I entered the Boston Globe, which was a temple to me then . It wasn’t easy getting hired. I had to fight my way in to a dime-a-word job. But once you were there, I found , you were in .
Globe jobs were for life-guaranteed until retirement. For 15 years I had prospered there—moving from an ordinary reporter to foreign correspondent and finally to senior editor. I would have a lifetime of security if I struck with it.
Instead, I had made a decision to leave.
I entered my boss’s office. Would he rage? I wondered. He had a famous temper. “Matt, we have to have a talk, ” I began awkwardly. “I came to the Globe when I was twenty —four. Now I’m forty . There’s a lot I want to do in life. I’m resigning. ”
“To another paper? ” he asked.
I reached into my coat pocket, but didn’t say anything, not trusting myself just then.
I handed him a letter that explain everything. It said that I was leaving to start a new media company. That the Globe had taught me in a thousand ways. That we were at a rare turning point in history, I wanted to be directly engaged in the change.
“I am glad for you , ” he said , quite out of my expectation. “ I just came from a board of directors meeting and it was seventy-five percent discouraging news. Some of that we can do deal with. But much of it we can’t ,” he went on. “I wish you all the luck in the world, ”be concluded. “And if it doesn’t work out , remember ,your star is always high here.”
Then I went out of his office, walking through the newsroom for more good-byes. Everybody was saying congratulations. Everybody—even though I’d be risking all on an unfamiliar venture : all the financial security I had carefully built up.
Later, I had a final talk with Bill Taylor, chairman and publisher of the Boston Globe. He had turned the Globe into a billion-dollar property.
I’m resigning, Bill, ” I said. He listened while I gave him the story. He wasn’t looking angry of dismayed either. After a pause, he said, “Golly, I wish I were in your shoes.

Think back to this time last year. What was on your mind?
Most likely, you were thinking about finals or the holidays, although in this city I’ve noticed that thinking about the holiday is a fancy way of saying how much stuff will I get.
Now reflect on your thoughts for this holiday season. Most people are still thinking about the holidays, but I say that with a grain of salt. Everybody with a functioning brain and the ability to communicate knows that this holioday season comes with a pretty large price tag: the debt of all the hardships, both domestic and foreign, that we’ve faced over the past 12months.
Let’s face it: some of us will get everything we want over the holidays. But there are others whose parents have lost their jobs or who have lost jobs themselves because of the current economic situation. As much as we try to ignore it, there is still economic unrest in the blue and gold suburb.
In this situation, we have three options. One: We ignore the situation, like we seem to do for every bad thing that happens around us, because by God, it’s the American Way! Two: We recognize that our economy is shot, feel bad about it and spend our time wishing for the good old days. Three: We recognize that our economy is shot, but instead of moping, reflect on every good thing that we have going for us. Now, which option sounds best to you?
I spent a week this summer working in and around New York City with the city’s homeless population. Or so I thought. Although a lot of the people I served were in fact homeless, a significant number of them had a job or a home or both. The truth of the importance of this situation is that they and thousands of others across the country can’t afford even the most basic things of life, even while working two jobs. Yet no one that I met complained about their hardships. Instead, they took whatever I happened to give them(which was, more often than enough, not enough) and were genuinely grateful for what they had.
Wrap your heads around that statement for a second. These people worked their butts off to stay alive with minimal results, yet were overjoyed by a flimsy(脆弱的) paper plate with donated green beans on it. Although I am ashamed to admit it( both as a girthy figure and an affluent citizen), I have taken for granted most of my meals, let alone green beans, and I know for a fact that I am not alone.
64. According to the passage when people think about holidays they care much for ____.
A. where to spend their holidays             B. how to spend their holidays 
C. what they can get for their holidays        D. who they should go to visit
65. When the author wrote the article, the economic situation in his country ____.
A. began to go bad.   B. began to improve   C. was still serious   D. was favorable for middle class.
66. The author wrote the article mainly to advise people____.
A.to be thankful in time of hardship.    B. to spend their holidays in a wise way
C. to think little about their holidays     D. to help the country to sail through the crisis
67. It can be inferred from the passage that the writer is most probably ______.
A. a homeless child    B. an old professor   C. a famous scientist  D. a young student

Few of us act alone in the real world. Most things are done with the help or ideas of other people. Group projects are great practice for high school, college, and real life, when you will probably have a job that requires working with others. Right now, group projects can be fun and they often allow you to do a bigger, more interesting project than you could alone. With group work, you can actually learn more in less time.
Group projects also give you a chance to get to know kids you might not otherwise know or talk with. Group projects are also a great way to practice skills you’re not so sure of. For example: working on a deadline, staying organized, or being patient. And if you’re a little nervous talking in front of a group, a joint project can help you become more comfortable with it. Maybe your group will pick you to tell the whole class about your project. If so, you’ll know your whole group is rooting for you!
One of the most important things about group work is talking and meeting together. It’s a good idea to continually check with everybody on their progress to see if anyone needs help. You might think the first step is to figure out who will do what, but actually it’s getting to know another a little. Take a few minutes to chat. Even if you know each other well, it can help to take a minute to think about your skills and share your strengths and weaknesses. The second step is to go over ground rules from your teacher and any that you want to create together as a group.
【小題1】Group projects can give you a chance to do the following EXCEPT ________.

A.get to know more friendsB.learn more than you do alone
C.work in an organized wayD.get rid of shyness forever
【小題2】The underlined phrase “root for” in the second paragraph means _______.
A.likeB.supportC.offerD.prevent
【小題3】What’s the purpose in checking others’ progress?
A.To learn what they will do next.
B.To find good topics to talk with them about.
C.To help them when they need help.
D.To make sure that their work is finished on time.
【小題4】 According to the passage, we can infer that _______.
A.group members should be your close friends
B.talking with group members should be the first step of group work
C.knowing persons is more important than your projects
D.rules from teachers are more important than working among group members
