问题补充：

The homework is not as heavy as he used to get. All he needs to do is improve English.

A. what, that

B. that, which

C. which, that

D. what, which

答案：

(答案→)A. what, that

B. that, which

C. which, that

D. what, which

解析：在as引导的比较状语中缺少get的宾语，故用what，排除BC；第二空后he needs to do是定语从句，当先行词是all时关系词用that，不能用which，故选A。
