题目内容
When I try to understand ________ that prevents so many children from being happy, there seem to be three causes.
| A．why it is | B．what it does | C．why it does | D．what it is |
D
解析试题分析：句意：当我试图理解是什么阻止这么多的孩子快乐，似乎有三个原因。这里使用了强调句的特殊问句，因为that后面缺少主语，所以用疑问词what，又因为这个强调句的特殊问句是做understand的宾语从句，所以语序要变成陈述句语序。所以选D。
考点：考查强调句的特殊问句和宾语从句
