When we can see well, we do not think about our eyes often. It is only when we can not 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 and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly.
People who are farsighted face 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. 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 eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the side 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 your 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 can not see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark.

举一反三
Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.
小题1:
The most important points of trees to man is ________.A.they help him to make money |
B.they give him cool |
C.they give him wood and other things |
D.they help him to stop drought and floods |
小题2:
In many places forests slowly disappear because ________ .A.many trees have been cut down by man |
B.new trees are not well looked after |
C.man has not paid enough attention to planting trees |
D.all the above |
小题3:
Land becomes desert after all trees are cut down because ________ .A.roots of trees break up the soil |
B.there are too many rainfalls |
C.strong winds bring a lot of sand |
D.there are no longer trees to keep the rain and protect the top-soil. |
小题4:
Which title best fits the passage?A.Trees and Man. |
B.The Function of Tree Wood. |
C.How do People do with Trees? |
D.The Usage of Tree Roots. |
Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time: if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’s. In the same way, children learning to do all the other things: they learn to do without being taught to walk, run, climb, whistle, ride a bicycle, compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not.If it is a matter of right answer, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine(常规) work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, and how to know what they know or do not know.
