(单选题)

She was so angry at he was doing she walked out without a word.

A.what; that

B.that; what

C.that; that

D.what; what

参考答案：A

参考解析：

考查what引导的宾语从句和so…that引导的结果状语从句。句意：她对他的所作所为太生气了，以至于什么都没说就走了。其一，“______ he was doing”作at的介宾从句，宾语从句中缺宾语，排除that，排除B和C。其二，结果状语从句表示“如此……以至于”，又与so搭配，用that,故排除B。故选A。

知识点：

She was so angry at ______ he was doing ______ she walked out without a word.

She was so angry at he was doing she walked out without a word.
