The homework is not as heavy as ________he used to get. All________ he needs to do is to improve English.
A．what, that B．that, which C．which, that D．what, which
【回答】
A
【详解】
考查比较状语从句和定语从句。句意：家庭作业没有他以前的那么繁重了。他所要做的就是要提高英语。在as引导的比较状语中缺少get的宾语，故用what。第二空后he needs to do是定语从句，当先行词是all时且指物时，关系词用that，不能用which。故选A。
知识点：状语从句
题型：选择题
