Why did the chicken cross the road? To get to the other side. Most people know this joke. But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road.
“ Millions of animals die each year on the U. S. roads, ” the Federal Highway Administration reports. In fact, only about 80 ocelots , an endangered wild cat, exist in the U. S. today. The main reason? Roadkill.
“Eco-passages" may help animals cross the road without being hit by cars. They are paths both over and under roads. “ These ecopassages can be extremely useful，so that wildlife can avoid road accidents ,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the eco-passages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway. This showed that the lions used the passage.
Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders (火蜥蜴)and grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal over-pass ！The writer uses the example of "ocelots" to show that __________.
| A．an increasing number of animals are killed in road accidents |
| B．the driving conditions have improved greatly |
| C．the measure for protecting wildlife fails to work |
| D．wild animals have become more dangerous |
From the passage, we know an eco-passage is __________.
| A．an underground path for cars |
| B．a fence built for the safety of the area |
| C．a path for animals to cross the road |
| D．a bridge for animals to get over a river |
When the writer says that animals seem "to be catching on" , he means __________.
| A．animals begin to realize the danger on the road |
| B．animals begin to learn to use eco-passages |
| C．animals are crossing the road in groups |
| D．animals are becoming safer |
The writer asks visitors and drivers to look around when they are traveling because __________.
| A．wild animals may cause danger |
| B．wild animals may jam the road |
| C．they may kill the animals |
| D．they may see wild animals on eco-passages |
This passage is written to __________.
| A．protect the endangered animals |
| B．call on drivers to be careful when they see animals on the road |
| C．introduce a new way to help protect wild animals |
| D．tell us the main reason for the killing of animals in the U. S. |
It would be pleasant to believe that all young girls in the past got married for romantic reasons; but the fact is that many of them regarded marriage as their only chance to gain independence from their parents, to have a provider, or to be assured of a good place in society. A couple of generations ago, an old maid of twenty-five did not have much to look forward to, she was more or less fated to remain with her parents or to live in some relative’s home where she would help with the chores and the children. Not so any more. In the first place, women remain young much longer than they used to, and an unmarried woman of twenty-eight or thirty does not feel that her life is over. Besides, since she is probably working and supporting herself, she is free to marry only when and if she chooses. As a result, today’s women tend(倾向) to marry later in life. They have fewer children-or none at all—if they prefer to devote themselves to their profession. The result is a decline in the birthrate.
The new role that women have developed for themselves has changed family life. Children are raised differently; they spend more time with adults who are not their parents: baby sitters, day-care center personnel, relatives, or neighbors. Whether they gain or lose in the process is a hotly debated question. Some child experts believe that young children must spend all their time with their mother if they are to grow sound in body and mind. Others think that children get more from a mother who spends with them “quality time” (a time of fun and relaxation set aside for them) rather than hours of forced and unhappy baby sitting. And many child psychologists point out that children kept in day-care centers every day are brighter than those raised at home. No matter what it is, one thing about child-raising to be certain of is that the longer the child is with the mother, the better.It can be concluded from the passage that______.
| A．women today have developed a new role in family life |
| B．the birthrate is declining as a result of women’s pursuit (追求) of careers |
| C．women have always been dependent on their parents even after marriage |
| D．children must spend all their time with their mother if they are to grow sound |
The change in women’s attitude towards marriage results in all of the following EXCEPT _________.
| A．more and more women quit (leave) jobs to take care of their children at home |
| B．women today tend to marry later than they did |
| C．women have less time to raise children |
| D．more and more families remain childless |
People have different opinions over the question as to______.
| A．how children should be raised |
| B．where children should be raised |
| C．whether children should stay with their parents |
| D．how long children should stay with their parents |
The author suggests that______.
| A．working women should not have children |
| B．children should be kept in day-care centers all the time |
| C．young children should stay with their mother as long as possible |
| D．women should leave their work to look after their children at home |
The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other for ever. He sent his camera crew (摄制组) out one evening to film the sunset for him.
The next morning he said to the men, “Have you provided me with the sunset?”
“No, sir.” The men answered.
The director was angry. “Why not?” he asked.
“Well, sir,” one of the men answered, “we are on the east coast here, and the sun sets in the west. We can get a sunrise over the sea, if necessary, but not a sunset.”
“But I want a sunset!” the director shouted.” Go to the airport, take the next flight to the west coast, and get one.”
But then a young secretary had an idea,” Why don’t you photograph a sunrise,” she suggested, “and then play it backwards? Then it would look like a sunset.” “That’s a good idea!” the director said. Then he turned to the camera crew and said,” Tomorrow morning I want you to get me a beautiful sunrise over the sea.”
The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of the beautiful bay(海湾).Then at nine o’clock they took it to the director. “Here it is, sir.” They said and gave it to him. He was very pleased.
They all went to the studio. “All right,” the director explained, “now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the ‘sunset’ behind them.”
The “sunset” began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.
The birds in the film were flying backwards, and the waves on the sea were going away from the beach.One evening, the director sent his camera crew out______.

| D．because he was disappointed with the performance of the hero and heroine |
Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict,” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled (皱的).” Today David wears casual clothes — khaki pants and a sports shirt — to the office. He hardly ever wears a necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”
More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the changes from formal to casual office wear have been slow. In the early 1990s, many companies allowed their workers to wear casual clothes on Friday (but only on Friday).This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for workers has really become an everyday thing,” said business adviser Maisly Jones.
Why have so many companies started allowing their workers to wear casual clothes? One reason is that it's easier for a company to attract new workers if it has a casual dress code. “A lot of young people don't want to dress up for work,” says the owner of a software company, “so it's hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study made by Levi Strauss and Company, 85 percent of employers said that casual dress has a side effect on work. Supporters of casual office wear also say that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”David Smith refers to himself as having been “a clothes addict” because ______________.
| A．he often wore khaki pants and a sports shirt |
| B．he couldn't stand a clean appearance |
| C．he wanted his clothes to look tidy and clean all the time |
| D．he didn’t want to spend much money on clothes |
David Smith wears casual clothes now, because ______________.
| A．they make him feel at ease when working |
| B．he cannot afford to buy expensive clothes |
| C．he looks handsome in casual clothes |
| D．he no longer works for any company |
According to this passage, which of the following is TRUE?
| A．Company workers started to dress down about thirty years ago. |
| B．Dress-down has become an everyday phenomenon since the early 1990s. |
| C．“Dress-down Friday” was first given as a favor from employers. |
| D．Many workers want to wear casual clothes to impress people. |
D. he no longer works for any company

A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct(不同的) species.
The discovery was made by researchers at York and Harvard Universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants — the Asian elephant, African forest elephant, and African savanna elephant.
Once they obtained DNA sequences(序列) from two fossils(化石), mammoths，and mastodons the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephant and the African forest elephant have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists. There has long been debate in the scientific community that the two might be separate species, but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species, despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5 metres while the forest elephant has an average shoulder height of 2.5 metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the Department of Animal Sciences at the University of Illinois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purposes. Since 1950，all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinctive animals, the forest elephant should become a bigger priority(优先) for conservation purposes.”One of the fossils studied by the researchers is that of _____.
| A．the Asian elephant | B．the forest elephant |
| C．the savanna elephant | D．the mastodon elephant |
The researchers’ conclusion was based on a study of the African elephant’s _____.
| A．DNA | B．height |
| C．weight | D．population |
What are Alfred Roca’s words mainly about?
| A．The conservation of African elephants. |
| B．The purpose of studying African elephants. |
| C．The way to divide African elephants into two units. |
| D．The reason for the distinction of African elephants. |
Which of the following can be the best title for the passage?
| A．Naturalists’ Beliefs about Elephants |
| B．Amazing Experiments about Elephants |
| C．An Unexpected Finding about Elephants |
| D．A Long Scientific Debate about Elephants |
Blind imitation (模仿)is self-destruction. To those who do not recognize their unique worth， imitation appears attractive；to those who know their strength. Imitation is unacceptable.
In the early stages of skill or character development, imitation is helpful. When I first learned to cook, I used recipes (菜谱) and turned out some tasty dishes. But soon I grew bored. Why follow someone else’s way of cooking when I could create my own? Imitating role models is like using training wheels on a child’s bicycle; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.
In daily life, imitation can hurt us if we subconsciously (下意识地) hold poor role models. If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others.
In the field of entertainment, our culture glorifies celebrities. Those stars look great on screen. But when they step off screen, their personal lives may be disastrous. If you are going to follow someone, focus on their talent, not their bad character or unacceptable behaviors.
Blessed is the person willing to act on their sudden desire to create something unique. Think of the movies, books, teachers, and friends that have affected you most deeply. They touched you because their creations were motivated by inspiration, not desperation. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. Creative people have an endless resource of ideas. The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination.
Study your role models, accept the gifts they have given, and leave behind what does not serve you. Then you can say,” I stand on the shoulders of my ancestors tragedies and declare victory, and know that they are cheering me on.Imitation proves useful when you .
| A．know you are unique |
| B．lose the balance of life |
| C．begin to learn something new |
| D．get tired of routine practice |
To avoid the bad result of imitation, we should________.
| A．forget daily fear and pain | B．choose the right example |
| C．ask others for decisions | D．stay away from stars |
The trouble a creator faces is .
| A．the lack of strong motivation |
| B．the absence of practical ideas |
| C．how to search for more materials |
| D．how to use imagination creatively |
What is the author’s purpose in writing this passage?
| A．To highlight the importance of creatively. |
| B．To criticize the characters of role models. |
| C．To compare imitation with creation. |
| D．To explain the meaning of success. |
