When 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 near-sighted can only see things that are very close to their eyes, Everything else seems blurry(=unclear). Many people who do a lot of work, such as writing, reading and sewing become near—sighted. Then people who are far-sighted 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 (白內(nèi)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 out of your other eye. You will find the object’s relation to the background 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.

39. We should take good care of our eyes ________.

A. only when we can see well             

B. only when we cannot see perfectly

C. even if we can see well    

D. only when we realize how important our eyes are

40. When things far away seem indistinct(模糊不清) , one is probably _________.

A. near-sighted          B. far-sighted

C. astigmatic              D. suffering from cataracts

41. The underlined word suffer from in the second paragraph probably means _____.

A. experience        B. imagine      C. feel pain     D. are affected with

42. People who suffer from astigmatism have __________.

A. one eye bigger than the other  

B. eyes that are not exactly the right shape

C. a difficulty that can be corrected by an operation

D. an eye difficulty that cannot be corrected by glasses

43. Having two eyes instead of one is particularly useful for _________.

A. seeing at night                    B. seeing objects far away

C. looking over a wide area          D. judging distances

閱讀理解
     When you see geese flying along in V formation, you might consider what science has discovered
as to why they fly that way.
     As each bird flaps wings, it creates an uplift for the bird immediately following. By flying in V
formation, the whole flock at least 71 per cent greater flying range than if each bird flew on its own.
Individuals who share a common direction and sense of community can get where they are going more
quickly and easily because they are travelling on the pushing force of one another.
     When a god se falls out of formation, it suddenly feels the drag and resistance of trying to go it alone,
and quickly gets back into formation to take advantage of the lifting power of the bird in front. If we
have as much sense as a goose, we will stay in formation with those people who are headed the same
way we are.
     When the head goose gets tired, it moves back in the formation and another goose flies point. It is
sensible to take turns doing demanding jobs, whether with people or with geese flying south.
     Geese honk from behind to encourage those up front to keep up their speed. What messages do
we give when we honk from behind?
     Finally -and this is important -when a goose gets sick or is wounded by gunshot, and falls out of
formation, two other geese fall out with that goose and follow it down to lend help and protection.
They stay with the fallen goose until it is able to fly or until it dies, and only then do they launch out on
their own, or with another formation, to catch up with their group.
     If we have the sense of a goose, we will stand by each other like that.
1. By flying in "V" formation, a goose can ______.
A. learn who leads the group         
B. see the direction ahead clearly
C. fly at a higher speed and reach a further place    
D. greatly reduce the risk of being hit by gunshots
2. What does the underlined word "honk" mean?
A. To fly.   
B. To move.  
C. To cry.          
D. To fight.
3. Which of the following is NOT suggested in the text?
A. We should be united as one to achieve a common goal.
B. We should work together with those who share our dream.
C. We should take our share of responsibility in a huge task.
D. We should encourage those falling behind to keep on trying.
4. What's the main purpose of the text?
A. To encourage us to learn from geese.
B. To announce some new findings about geese.
C. To prove the similarities between humans and geese.
D. To persuade us to find more about life of geese.
