Was John’s quick action and knowledge of first aid saved her life?

A. it, which

B. that, what

C. it, that

D. it,/

答案：

A. it, which

B. that, what

(答案→)C. it, that

D. it,/

解析：考查强调句型。强调句型的基本结构：it is/was被强调成分that/who其它成分；其最大的特点是把it is/was…that/who…去掉，句子仍然成立。本题强调的是主语John’s quick action and knowledge of first aid；句意：是约翰迅速的行动和急救知识救了她的名吗？故C正确。
