()21. What he did at the party everyone deeply. We all admired his courage.

A.surprised
B.surprises
C.surprising

21.A

【分析】首先分析句子结构，空格处位于主语从句“What he did at the party”之后，需充当句子的谓语动词，因此先排除无法作谓语的选项C（surprising为形容词或非谓语形式，不能作谓语）；再根据时态一致原则，后半句的谓语动词“admired”是一般过去式，前后时态需保持一致，故空格处应使用动词的过去式，结合选项选出正确答案。
【解析】句子主语是主语从句，空格处需作谓语，C项surprising不能作谓语，排除；后半句admired为一般过去时，前后时态需一致，因此用动词过去式surprised，对应选项A。
【答案】A
【知识点】一般过去时；谓语动词
【点评】本题考查谓语动词的用法及时态一致，属于基础语法题，侧重对基础知识点的应用。
【难度系数】0.7
