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

Answer 1

D

试题分析源旁：句意：当我试图理解是什么阻止这么多的孩子快乐，似乎有三个乱塌原因。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雹陪橡序。所以选D。
