4. If we all make a contribution to _________ the environment, the world will become much more beautiful.
A. protecting B. protected C. protect D. protects

选什么?

A
make a contribution to doing sth

A

A

contribution贡献

contribution to/towards sth,to是介词

protect变为protecting,动名词

选C.
这的to protect是目的状语,不是make a contribution to sth/doing sth的词组.根据语意可知:为了保护环境人人出一份力,世界会变得更美好.

我被搞糊涂了！

C
[to后要+动词原型]
