She was so angry at he was doing she walked out, and closed the door heavily behind her.

A. what; that

B. that; what

C. that; that

D. what; what

答案：

(答案→)A. what; that

B. that; what

C. that; that

D. what; what

解析：第一空“he was doing” 是angry at 接的一个宾语从句，该宾语从句缺宾语，故用what；第二空要从整个句子来考虑，“so...that”是固定搭配，意思是：如此...以至于...。这句话的意思是“她对他所做的事如此的生气以至于走了出去并狠狠地关上了门。”
