1. It was when the private company successfully launched astronauts into space__________I knew it would open up more opportunities in the space industry.
A. which B. how C. where D. that
【答案解析】 D
【详解】考查强调句型。句意：当私人公司成功地将宇航员送入太空时，我知道这将为航天工业开辟更多的机会。强调句型的结构为It is/was + 被强调部分+that/who +其它。当被强调内容为人时，用who,其它全部用that。该句式的特点为去掉It is/was和 that，其余部分在不添加内容的情况下，重写后依然为完整的句子。本句中去掉It is/was和 that，重写句子为：When the private company successfully launched astronauts into space, I knew it would open up more opportunities in the space industry.其中when…space,为时间状语从句，其余部分为主语。句子结构完整。所以，选项D符合题意。故选D。
2. Fanny asked ________ made that oddlooking little cat so popular.
A. what was it that B. wat was that
C. what it was that D. what that was
【答案解析】 C
【详解】考查宾语从句和强调句。句意：他想知道是什么使她在最后一刻改变了主意。根据句意，他想知道是什么使她在最后一刻改变了主意。分析句子可知，空格处引导宾语从句作 asked的宾语，从句中缺少表语，所以应用 what 引导。又因为从句中包含一个强调句，所以应用 “it is (was) that + 其他” 的结构，强调宾语从句的主语 what，故此处应为 what it was that。故正确答案为C。
