Although you have learned much knowledge

问题选择题

Although you have learned much knowledge and a lot of theories, the problem is _______ can be put into practice.

A．what you have learned

B．how what you have learned

C．that what you have learned

D．how that you have learned

答案

题目分析：考查表语从句。本题中how引导起该表语从句，what you have learned在表语从句中做主语，what在该主语从句中做动词learn的宾语。句意：尽管你已经学会了很多知识和理论，问题是你如何把你所学的知识付诸实施。故B正确。

点评：在该表语从句中how是引导词，what引导起表语从句中的主语从句。在名词性从句中要注意死于陈述语序，同时也要注意引导词的选择。
