Question

As a member of one world, each of us has a role _____ to make the earth a better place

1. A.
   playing
2. B.
   play
3. C.
   played
4. D.
   to play

Answer 1

D
试题分析：句意：作为世界的一员，我们每个人都要发挥作用，使地球成为一个更好的地方。“have sth. to do” 意为“有某事要做”，play a role:发挥作用；扮演一个角色。这里要跟 have sth. done 使某事、物被…, 和have sb. do,使/让某人做某事区分开。故D正确。
考点：考查分词作补语。
