【题目】When we can see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we come to see how important our eyes are.

People who are nearsighted can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing, reading and sewing(缝纫), become nearsighted. Then they have to wear glasses in order to see distant things clearly.

People who are farsighted(远视的)suffer from just the opposite problem. They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses too.

Other people do not see clearly because their eyes are not exactly the right shape. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts(白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

When night falls, colors become fainter to the eye and finally disappear. After your eyes have grown used to the dark, you can see better if you use the sides of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn you head in its direction. This is because when you turn your head, you are looking at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they cannot see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive(敏感的) in daylight, is not as sensitive as the sides of the eyes after dark.

【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. Knowing how to go through your math test and check your work can save you from handing in a test full of mistakes that can be avoided. 1

Write it out

You can also check a math problem by writing everything out on paper. 2 Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

3

Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether or not your answer is the correct one.

Plugging in

You may find that a variable isn’t good enough or have a problem where you have to solve for a variable (变量). 4 This is the only real way to assure yourself that the answer you’ve found is correct.

Check for a reasonable answer

5 For example, if you get an answer in the millions and you know it should be in the thousands, you’ve likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you’ve got on the first try.

A. Do the opposite

B. Correct the answers

C. Plug the variable in the equation (方程) to check it out.

D. Therefore you’ll improve your grades, as well as your math skills.

E. It also helps you to figure out everything after you have already finished the test.

F. If the result of a problem seems to make no sense, it indicates that the answer is incorrect.

G. This helps you to know what information you have and what information you need to solve.

【题目】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

A tender woman, or an independent one, which one would you prefer? A recent research shows that most people would choose the latter.

This type of woman is called a nühanzi (“tough woman”). Experts believe these characteristics have social and psychological roots among young females in China. Su Hao’s friends all call her a tough woman, because she can finish tough tasks usually carried out by men. For example, she carries 10-litre water to her dormitory on the 5th floor. “I depend on no one but myself,” she says.

According to a recent survey by China Youth Daily, tough women have become rather common in society. Of the 21,265 respondents, 78.5 percent said they are familiar with a tough woman. About 50 percent said they like women with tough characteristics, while less than 29 percent expressed the opposite view.

Why are tough women gaining popularity? Shen Meng, a psychological consultant, believes the fierce competition in society is contributing to this trend. “Women are often in a disadvantaged position compared to men,” Shen says. “In order to survive, they have to be independent, strong and tough.” Liu Xiaolin, professor of psychology at Wuhan Mental Health Center, believes tough women are brought up this way. They are often on close relationship with their fathers, who teach their daughters to be brave and decisive,” he says. As a result, these women are more likely to be psychologically healthy and more tolerant to stress, according to Liu.

Though Liu believes that this is a good trend, Hu Shenzhi, a psychologist at the Guangdong Sunflower Counseling Center, says the popularity of tough woman indicates an unclear line between gender identities, which can lead to relationship problems. “Some women with characteristics that differ from the traditional female image may have a difficult time finding Mr Right,” he says. “Even if they get married, their manly characteristics might cause family conflicts.

【2】How many respondents like tough women?

A. about 21,265. B. about 16,700

【3】Why are there more tough women nowadays?

A. Because tough women are more lovely.

B. Because of the fierce competition in society.

C. Because girls often love fathers more.

D. Because more women want to be independent.
