Passage TwoWhen we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.People who are nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.People who are nearsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in 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. They have what is called astigmatism (散光). 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.Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object outof the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.40. We should take good care of our eyes ______.A. only when we cannot see perfectlyB. only when we can see wellC. even if we can see wellD. only when we realize how important our eyes are

The First Four MinutesWhen do people decide whether or not they want to become friends?During their first four minutes together,according to a book by Dr. Leonard Zunin.In his book,Contact:The First Four Minutes,he offers this advice to anyone interested in starting new friendships:"________(46)A lot of people's whole lives would change if they did just that."You may have noticed that the average person does not give his undivided attention to someone he has just met._________(47)If anyone has ever done this to you,you probably did not like him very much.When we are introduced to new people,the author suggests,we should try to appear friendly and self-confident. In general,he says,"People like people who like themselves".On the other hand,we should not make the other person think we are too sure of ourselves.It is important to appear interested and sympathetic,realizing that the other person has his own needs,fears,and hopes.Hearing such advice,one might say,"But I'm not a friendly,self-confident person.That's not my nature.It would be dishonest for me to act that way."__________(48)We can become accustomed to any changes we choose to make in our personality."It is like getting used to a new car. It may be unfamiliar at first,but it goes much better than the old one."But isn't it dishonest to give the appearance of friendly self-confidence when we don't actually feel that way?Perhaps,but according to Dr. Zunin,"total honesty"is not always good for social relationships, especially during the first few minutes of contact. There is a time for everything,and a certain amount of play-acting may be best for the first few minutes of contact with a stranger. That is not the time to complainabout one's health or to mention faults one finds in other people.It is not the time to tell the whole truth about one's opinions and impressions.________(49)For a husband and wife or a parent and child,problems often arise during their first four minutes together after they have been apart. Dr. Zunin suggests that these first few minutes together be treated with care.If there are unpleasant matters to be discussed,they should be dealt with later.The author says that interpersonal relations should be taught as a required course in every school,along with reading,writing,and mathematics.__________(50)That is at least as important as how much we know._________（49）A:In reply,Dr. Zunin would claim that a little practice can help us feel comfortable about changing our social habits.B:Much of what has been said about strangers also applies to relationships with family members and friends.C:In his opinion,success in life depends mainly on how we get along with other people.D:Every time you meet someone in a social situation,give him your undivided attention for four minutes.E:He keeps looking over the other person'S shoulder,as if hoping to find someone more interesting in another part of the room.F:He is eager to make friends with everyone.
