1.第二段“Germs are everywhere.”的描述可知，細(xì)菌到處都有。A、B、C選項不符合原文內(nèi)容，故選D。

2. are everywhere. They are very small and you can’t find them with your eyes, but you can see them with a mi?croscope.”的描述可知，我們用肉眼是看不見細(xì)菌的，但在顯微鏡的幫助下，我們卻能看得很清楚。可見顯微鏡的作用是把東西放大。故選A。

3. are always found in dirty water.”的描述可知，父母不會讓孩子喝臟水，是因為“There must be lots of germs in it”（里面有很多細(xì)菌）。答案選C。

4.“Germs are everywhere”的描述可知，即使你的手沒有受傷，上面也會布滿細(xì)菌。因此A、B、C的敘述是不正確的。故選C。

5. makes us ill? It is Germs.”的描述可知， 這篇短文的主題是“Germs may make us ill”（細(xì)菌能讓人生�。�，故選A。
