问题描述：
There are so many books that I can't decide _____
A.which one to choose
B.what to choose
我认为是B答案,A答案好像后面要加from
答
A.which one to choose
答
选A which引导的宾语从句，意义上代表“选择哪一个”
what引导宾语从句时，意义上代表去选的内容是“什么”
choose是及物动词 后面可以直接跟选择的物品，不用非要加介词from
答
B.what to choose
你说的完全正确,一种是不定式结构做宾语,一种是定语从句.
答
我怎么觉得是A呢，要加from,因为前面说有很多书，要从中挑选。即I can't decide to choose one book from so many books.
