单选题 It was the training______made him such a good engineer.
【正确答案】 A
【答案解析】解析:语法题。本题考查强调句型的用法,故选A。强调句型即:it is/was+被强调成分that+原句子的其它部分。强调句型可用来强调句中的主语/宾语/宾语补足语/状语/状语从句等,但是不能强调谓语和定语或定语从句。强调间接宾语时通常需用介词。若原句的时间背景为过去,则用it was,若时间背景为现在,则用it is。当被强调的部分为人时,that可以用who代替,但其它的情况一般只能用that。需要特别指出的是当宾语为them时,强调句内要改用those,如:The professor regarded them with such contempt.若欲强调句中的宾语them,则强调句应为It was those the professor regarded with such contempt.
