问题补充：

Mr Smith was so angry at all Robert was doing he walked out angrily.

A. that; what

B. that; that

C. which; which

D. what; that

答案：

A. that; what

(答案→)B. that; that

C. which; which

D. what; that

解析：第一个空考查的是定语从句， all做先行词，后面缺少宾语，因此用that;第二个空考查的是：so … That 如此…… 以至于，句意：史密斯先生对 Robert做的事情如此的生气，以至于他生气地走了出去。故选B。
