题目内容
1．正是我国宇航员的精神才使我们克服了所有的艰难险阻．（enable）It was the spirit of astronauts/the astronauts'spirit of our country that enabled us to overcome all the difficulties．．分析 It was the spirit of astronauts/the astronauts'spirit of our country that enabled us to overcome all the difficulties．
解答 本句表达的是对我国宇航员精神的肯定及其带来的结果"使我们克服了所有的艰难险阻"，所以用一般过去时．
"正是我国宇航员的精神"，说明句子要表达的重点是"宇航员的精神"，因此句子需要一个强调句型，It was…that…句子强调的是主语．of our country 为一介词短语作后置定语．
enable sb to do sth意为"使某人能够做某事"；overcome意为"克服、战胜"．
点评 强调句型可以强调除谓语以外的其它成分，如主语、宾语和状语等．如：It was at the railway station that I met Li Ming yesterday．（强调地点状语）
