The secret of carrier pigeons' unbelievable ability to find their way home has been discovered by scientists: the feathered navigators follow the roads just like we do.
Scientists at Oxford University spent 10 years studying homing pigeons using global positioning satellite (GPS) and got a surprising result. The birds often don't use the sun to decide their directions. Instead, they fly along motorways, turn at crossings and even go around roundabouts (绕道) , adding miles to their journeys.
“It really has knocked our research team sideways to find that after a decade-long international study, pigeons appear to ignore their inbuilt directional instincts (本能) and follow the road system,” said Prof Tim Guilford, reader in animal behavior at Oxford University's Department of Zoology.
Guilford said pigeons use their own navigational system (导航系统) when doing long distance trips or when a bird does a journey for the first time.
“But once homing pigeons have flown a journey more than once, they can fly home on a habitual route, much as we do when we are driving or walking home from work,” said Guilford.
“In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their journeys as simple as possible.” What would be the best title of the passage?
| A．Birds Follow Roads as We Do. |
| B．Why Pigeons Can Fly Long Distance? |
| C．How Pigeons Find Their Ways Home? |
| D．Why Crows Fly the Shortest Distance? |
What does the underlined words "the feathered navigators" refer to?

| B．The crows. |
| C．Dogs. |
| D．Animals that can swim. |

Who owns the large American companies that produce cars, washing machines, and television sets? They are owned by a large group of people called stockholders.
A company must have money to build factories and to buy machinery. To get this money, it sells shares of stock（股份）. Each share of stock is a share in the ownership of the company. The person who buys a share of stock becomes a part owner of the company. He is called a stockholder. A company can have thousands of stockholders. Sometimes a very large company is owned by millions of stockholders.
Few persons can afford to buy a whole company, but the average individual can become part owner of a business. He can save his dollars and buy a share of stock in a large company. A person does not have to be wealthy to be a stockholder.
When a company makes money, each stockholder may receive a dividend(股息) check, which is his share of the profits（利润）. Parts of a company’s profits are not paid out to the stockholders. This money is used by the company so it can grow larger. If the company does well, its shares of stock become more valuable.
More than 20 million people own shares of stock in America’s companies. By owning stock, they are helping America’s businesses grow. They are also putting their money to work to earn more money. The story makes you think that _____.

A Brooklyn man who was quarreling with his girlfriend yesterday threw a dog off the balcony（阳台） of her 23rd-story apartment in TriBeCa, killing it, the police said.
The man, John Jefferson, 43, of Bedford-Stuyvesant, has been charged（指控） with robbery, criminal possession of a weapon and animal cruelty, the police said. He was taken to Bellevue Hospital Center yesterday for psychiatric evaluation（精神病鉴定）, they said.
The incident began shortly before 11 a.m., the police said, when Mr. Jefferson went to visit his girlfriend, Eugenia Miller, 41, at her apartment on 80 North Moore Street. She had filed a police report on Friday accusing（控告）Mr. Jefferson of stealing from her, but yesterday she allowed him in and they began arguing, the police said.
Mr. Jefferson threatened Ms. Miller with a knife, and she called 911, the police said. When officers arrived at her door, she ran into the hallway and Mr. Jefferson stayed in the apartment, they said.

Some students get so nervous before a test, they do poorly even if they know the material. Sian Beilock has studied these highly anxious test-takers.
Sian Beilock: “They start worrying about the consequences. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry, it actually uses up attention and memory resources.I talk about it as your cognitive horsepower that you could otherwise be using to focus on the exam.”
Professor Beilock and another researcher, Gerardo Ramirez, have developed a possible solution. Just before an exam, highly anxious test-takers spend ten minutes writing about their worries about the test.
Sian Beilock: “what we think happens is when students put it down on paper , they think about the worst that could happen and they reappraise the situation. They might realize it’s not as had as they might think it was before and, in essence(本质上), it prevents these thoughts from popping up when they’re actually taking a test.”
The researchers tested the idea on a group of twenty anxious college students. They gave them two short math tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.
The researchers added to the pressure. They told the students that those who did well on the second test would get money. They also told them that their performance would affect other students as part of a team effort.
Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.
Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test.
Prefessor Beilock says highly anxious students who did the writing got an average grade of B+, compared to a B- for those who did not.
Sian Beilock: “What we showed is that for students who are highly test-anxious, who’d done our writing intervention, all of a sudden there was no relationship between test anxiety and performance. Those students most likely to worry were performing just as well as their classmates who don’t normally get nervous in these testing situations.”
But what if students do not have a chance to write about their fears immediately before an exam or presentation? Professor Beilock says students can try it themselves at home or in the library and still improve their performance. What may happen if students have the problem of test anxiety?
| A．Test anxiety can improve students’ performance to some degree. |
| B．Students’ attention and memory resources run out when worried. |
| C．Students may not be admitted into their favorite college if worried |
| D．Test anxiety is sure to cause students to fail the test. |
Which of the following if TRUE?
| A．In the first math test, students who sat quietly performed better. |
| B．In the second math test, students who wrote about their feelings did worse. |
| C．Some college students are highly anxious test-takers while others are not in the tests. |
| D．The result in the math test agrees with that in the biology test. |
What does the underlined phrase “popping up” mean?
| A．Giving out | B．Fading away | C．Becoming clearly | D．Appearing suddenly |
what is most probably Sian Beilock?
| A．A psychology professor. | B．A philosophy researcher. |
| C．A politics professor | D．A tutor |
What is the main idea of the passage?
| A．It is a common practice for students being worried before a test. |
| B．Being worried before tests does harm to students’ performance. |
| C．Anxious students overcome test anxiety by writing down fears. |
| D．It is important for students to overcome test anxiety. |
American society is not nap (午睡)-friendly. In fact, says David Dinges, a sleep specialist at the University of Pennsylvania School of Medicine, “There’s even a prohibition against admitting we need sleep”. Nobody wants to be caught napping or found asleep at work. To quote a proverb: “Some sleep five hours, nature requires seven, laziness nine and wickedness eleven.”
Wrong. The way not to fall asleep at work is to take naps when you need them. “We have to totally change our attitude toward napping,” says Dr. William Dement of Stanford University, the godfather of sleep research.
Last year a national commission led by Dement identified an “American sleep debt” which one member said was as important as the national debt. The commission was concerned about the dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, President Clinton is trying to take a ha1f-hour snooze (瞌睡) every afternoon.
About 60 percent of American adults nap when given the opportunity. We seem to have “a mid afternoon quiet phase,” also called “a secondary sleep gate.” Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap.
We Superstars of Snooze don't nap to replace lost shut-eye or to prepare for a night shift.Rather, we “snack” on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, cars, planes and on boats; on floors and beds; and in libraries, offices and museums.It is commonly accepted in American society that too much sleep is .
| A．unreasonable | B．criminal | C．harmful | D．costly |
The research done by the Dement Commission shows that Americans ________.
| A．don't like to take naps |
| B．are terribly worried about their national debt |
| C．sleep less than is good for them |
| D．have caused many industrial and traffic accidents |
The purpose of this article is to .
| A．warn us of the wickedness of napping |
| B．explain the danger of sleepiness |
| C．discuss the side effects of napping |
| D．convince the reader of the necessity of napping |
The underlined phrase “American sleep debt” in Para. 3 is the result of .
| A．the traditional misconception the Americans have about sleep |
| B．the new sleep policy of the Clinton Administration |
| C．the rapid development of American industry |
| D．the Americans' worry about the danger of sleepiness |
The second sentence of the last paragraph tells us that it is .
| A．preferable to have a sound sleep before a night shift |
| B．good practice to eat something light before we go to bed |
| C．essential to make up for cost sleep |
| D．natural to take a nap whenever we feel the need for it |
