Question

  Have you ever been ill? When you are ill,you must be unhappy because your body becomes hot,and there are pains all over your body. You don't want to work,and you stay in bed,feeling very sad.

   What makes us ill? They’re germs (細(xì)菌) . Germs are everywhere. They are very small and you can't find them with your eyes,but you can find them with a microscope. They are very small and there could be lots of them on every small thing.

   Germs are always found in dirty water. When we look at dirty water under microscope,we will see them in it. So your our parents will not let you drink dirty water.

   Germs aren’t found only in water. They are found in the air and dust (灰塵) . If you cut your finger,and if some of the dust from the floor goes into the cut,some of the germs would go into your finger. Your finger would become big and red,and you will have much pain in it. Sometimes the germs would go into all of your body,and you would have pain everywhere.

3. Where are germs?

4. What5s the main idea of the passage?

Answer 1

閱讀提示:本文是說明文。講述了細(xì)菌的相關(guān)知識(shí):細(xì)菌的危害、生存環(huán)境等。

1. Making very small things look much bigger.推理判斷題。由第 二段可知細(xì)菌非常微小;第三段把臟水放在顯微鏡下可以看到細(xì) 菌。說明顯微鏡的作用是放大微小物體。

2. Because there must be lots of germs in it.細(xì)節(jié)理解題。由第三 段可知，水里有很多細(xì)菌，因此父母不讓我們喝臟水。

3. They are everywhere. 細(xì)節(jié)理解題。由第二段第三句“Germs are everywhere. ”可知細(xì)菌到處都是。

4. Germs may make us ill. 標(biāo)題大意題。第二段起承上啟下的作 用，然后下文以此為話題展開說明。
