(14) Zinc(锌) is one of about 20 elements necessary for good health. It is present in the body in a very small amount but makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work. Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys formerly with the United States Air Force noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate. The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein foods such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these food. Food markets should add these elements so that more people could get needed amount of these necessary matters.

第二节: 信息匹配 (共5小题; 每小题2分，满分10分）

阅读下面一篇文章，文章后有七个选项，从A、B、C、D、E、F、G的七个选项中选出五个符合每一段文章主旨大意的选项。

To be a good teacher, you need some of the gifts of a good actor: you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear． (56)__________．

Watch a good teacher, and you will see that he does not sit motionless before his class: he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings．Listen to him, and you will hear the loudness, the quality and the musical note of his voice always changing according to what he is talking about． (57) _______________．

The fact that a good teacher has some of the gifts of a actor doesn’t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher’s work and the actor’s．The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand．What he has to do is to make all these carefully learnt words and actions seem natural on the stage． (58)_________________．

A good teacher works in quite a different way．His audience takes an active part in his play: they ask and answer questions, they obey orders, and if they don’t understand something, they say so．The teacher therefore has to suit his act to the needs of his audience, which is his class．He cannot learn his part by heart, but must invent it as he goes along． (59)_________________．

I have known many teachers who were fine actors in class but were unable to take part in a stage play because their brains wouldn’t keep discipline: they could not keep strictly to what another had written． (60)_______________．

A．Characteristics of a good teacher

B．Qualities of a good actor

C．What makes up a good teacher

D．What makes a teacher famous

E．It is not easy for a good teacher to become a good actor．

F．The image（印象）of a good teacher

G．Duties of a good teacher
