问题补充：

Don’t always believe him. Sometimes he does is quite different from what he says.

A. what

B. that

C. how

D. who

答案：

(答案→)A. what

B. that

C. how

D. who

解析：考察主语从句。本题中的what引导起主语从句what he does，并在句中作为动词does的宾语。句意：不要总是相信他。有时候，他做的事情和他说的不一样。That可以引导主语从句，但是在句中不充当任何成分，how只能在句中作状语，who只能指人。故A正确。
