She didn＇t know ________ to express her ideas in English clearly in public.
A
which
B
why
C
what
D
how
答案解析
正确答案：D
解析：
参考解析:句意推断。四个选项都可以带不定式结构做宾语，但从句意来看，这里需要表达"如何之意"即How to do sth"如何做某事”，所以确定选项为D，A项表示选择关系，题干并没有涉及到选择，不符合题意。B项中如果使用why，则必须在前加名词reason，比如she didn＇t know the reasonwhy..项what必须在whatto do句型中做宾语成分，而题千中to express her ideas并不缺少宾语成分。这三项均可以排除。句意:她不知道在公众面前如何用英语清晰地表达自己的观点。
