单选题One of the quickest and most effective ways to improve your vocabulary is by learning to recognize the most common Latin and Greek roots, since any one of them can help you define a number of English words. Whenever you come upon an unfamiliar word, first check to see if it has a recognizable root. If you know that the Latin root "ami" for example, means like or love, you can easily figure out that "amiable" means pleasant, friendly and "amorous" means loving. Even ff you cannot define a word exactly, recognizing the root will still give you a general idea of the word's meaning. Remembering that the Greek root "geo" means earth would certainly help you define "geophysics" as the physics of the earth, but it also might help you figure out that "geocentric" has to do with the center of the earth or with the earth as a center. Begin by studying the following lists of common Latin and Greek roots and representative words.

单选题When we can see well, we don't think about our eyes very' often. It is only when we cannot see perfectly that we come to see how important our eyes ale. 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, become nearsighted. Then they have to wear glasses in order to see distant things clearly. People who are farsighted 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 don't 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 age these people often became blind. Now, however, it is possible to operate on the cataracts and remove them. When night falls, colors become fainter (更暗淡的) 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 center. Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head to 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 eye after dark.

单选题A good memory is certainly very helpful for your study. However not everyone has a good memory. Besides, to forget things is not al- ways a bad thing. As a matter of fact, to forget certain things may help you remember more useful and meaningful things. I am sure everyone has this experience, that is, when you have learned something and remembered it, the memory will stay in your mind and you refuse to accept new ideas about it. If you find what you have remembered wrong, it is even more difficult to forget. In this sense, it is easier to remember new things than cast away wrong memories. There are things that you forget permanently (永久地) and things you forget only temporarily (暂时地). For instance (例子) , sometimes when you are doing mathematics, you just cannot think of a certain formula (公式). Or sometimes when you come across a friend, his name just escapes you. They are examples of temporary loss of memory. When this happens, you had better try to do some- thing else. And if you return to the maths some time later, you can most probably remember the formula. Needless to say you must try hard to get rid of wrong memories. But sometimes it is also necessary to forget forever things that are correct. For example, we may have watched hundreds of films since childhood. If we remember every film ( though this is not highly possible) , we will not be able to remember a lot of other things. That is why many films are gradually forgotten as time passes. Yet at the same time, we continue to remember new things. So remembering, forget- ting, forgetting, remembering, this is the cycle (循环) of our mind.
