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 out
of 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.
We should take good care of our eyes ______.
A.only when we cannot see perfectly
B.only when we can see well
C.even if we can see well
D.only when we realize how important our eyes are

D. only when we realize how important our eyes are
When we see well, we do not think about our eyes very often. (79) 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 seems blurry (模糊的). Many people who do a lot of close work, such as writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant objects clearly.
People who are farsighted 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.

Translate the following into Chinese.
Attention to detail is something everyone can and should do especially in a tight job market. Bob Grossley, a human-resources expert notices this in the job applications that come across his desk every day. “It’s amazing how many candidates eliminate themselves.” He says.
“Resume(简历) arrive with stains. Some candidates don't bother to spell the company’s mane correctly. On seeing such a mistake, I eliminate the candidate,” Crossley concludes. “If they cannot take of these details, why should we trust them with a job?”
Can we pay too much attention to detail? Absolutely. Perfectionists struggle over little things at the cost of something larger they work toward. “To keep from losing the forest of the trees”, says Charles Garfield, associate professor at the University of California, San Francisco, “we must constantly ask ourselves how the details we’re working on fit into the larger picture. If they don't, we should drop them and move to something else”.
Knowing where we want to go helps us judge the importance of every task we undertake.Too often we believe what accounts for others’ success is some special secret or a lucky break(机遇). But rarely is success so mysterious. Again and again, we see that by doing little things within our grasp well, large rewards follow.
