问题单项选择题

Whenever we hear of a natural disaster, we feel sympathetic to the people to be affected.()

A. to have affected

B. to have effected

C. who have been effected

D. who have been affected

答案

参考答案：D

解析：

时态应用。

动词不定式短语常表示将来要发生的动作，与本题意思不符，因而排除A、 B。题干中people后的affect表示“影响，侵袭”应该用被动式。effect做动词用时表示“招致，实现，达到(目的等)”，表示“影响”时是名词：The drug had an immediate effect on the pain．这药对止痛能立刻生效。
