Question

199. With the government’s aid, those ______ by the earthquake

have moved to the new settlements.
A. affect B. affecting C. affected D. were affected
答案C

Answer 1

选C， 首先是被影响，所以去掉AB
With the government’s aid, those affected by the earthquake have moved to the new settlements
在这里affected 是过去分词短语作定语，要放在被修饰的名词后面，作后置定语，其作用相当于一个定语从句， 相当于who were affected。
例如：
The student dressed in white is my daughter.
=The student who is dressed in white is my daughter. 穿白色衣服的学生是我的女儿
如果选D的话，句子就有了两个动词，语法就有问题了，而affected by the earthquake是定语，去掉也不影响句子成分
这样您能明白不

Answer 2

C，=who were affected
