Question

下面这个句子具体是哪里有问题，可以分析下吗？

Concerns were raised when witness might be encouraged to exaggerate to their stories in court to ensure guilty verdicts.
不好意思，多打了一个to, 应该是如下：
Concerns were raised when witness might be encouraged to exaggerate their stories in court to ensure guilty verdicts.

Answer 1

此题属于语法题。
本句中Concerns were raised是主句部分，witness might be encouraged...是从句，修饰名词concerns；而从句中主谓齐全，应该是concerns的同位语，故只有选项[D]that可引导同位语从句，是正确答案。选项[B]when在语意上与本句不符。选项[A] what不可引导同位语从句，一般引导主语从句或宾语从句，例如：What you have said confused me．又如：I will tell you what have happened．选项[C]which可用于引导主语从句、宾语从句或定语从句，考生应特别注意which引导的定语从句和that引导的同位语从句，要记住前者在从句中充当主语或宾语，而后者在从句中不充当成分，试比较：
1)The news which excited us is that our team has won．
2)The news that our team has won excited us all．
