There is pollution in the world. We must stop it.A. much too B.too much C. too many

问题补充：

There is pollution in the world. We must stop it.

A. much too B.too much C. too many

答案：

解析：句意：世界上有太多的污染，我们必须阻止。much too中心词是too,意思是太··· 用来修饰形容词;too much中心词是much,much此处意思是多,too作为副词修饰much,意思是太多，用来修饰不可数名词. too many 意思也是太多但用来修饰可数名词复数。本句中 pollution表示抽象含义，不可数，故选B。
