When you are ill, you must be unhappy because your body becomes hot, and there are pains all over. You don’t want to work. You stay in bed, feeling terrible.
　　What makes you ill? It is germs (细菌). Germs are everywhere. They are very small and you can’t see them with your eyes, but you can find them with a microscope. They are very small and there could be hundreds of them on or in a very small thing.
　　Germs are always in dirty water. When you look at dirty water under a microscope, you will see them in it. So your parents will not let you drink dirty water.
　　Germs are found not only in dirty water, they are also found in air and dust. If you cut your finger, and if some of the dust goes into the finger, it will become big and red, and you will have much pain in it. Sometimes they will go into your body and you will have pain everywhere.

　　【答案与解析】
　　短文大意是：细菌无处不在。脏水里，空气中或尘埃里通常含有大量细菌。它们是使人生病主要元凶。
　　1.D 从文首的两句话中，可直观地看出人生病时，身体发热，浑身疼痛，精神不愉快，也不想工作。故前三项皆包括在内。
　　2.B 虽然细菌无处不在，但根据"…They are very small and you can’t see them with your eyes, but you can find them with a microscope."一句可知正确答案为B。
　　3.B 通过a microscope可以看到小得肉眼看不见的细菌这个意思，我们可以推断出 microscope的意思是"显微镜"。根据常识，我们知道，显微镜是用来放大很小的东西的，而并非使其看起来更清楚些，也不是用来杀死细菌的。
　　4.B 上句说"在显微镜下观察脏水时会发现其中有许多细菌"，紧接着就说"So your parents will not let you drink dirty water."，因此，答案是B。
　　5.C 参看第三小题的分析。
　　6.D 第二段的"What makes you ill? It is germs."即是本题答案的出处。liuxuepaper.com
