Question

1．正是我國宇航員的精神才使我們克服了所有的艱難險阻．（enable）It was the spirit of astronauts/the astronauts'spirit of our country that enabled us to overcome all the difficulties．．

Answer 1

分析 It was the spirit of astronauts/the astronauts'spirit of our country that enabled us to overcome all the difficulties．

解答 本句表達的是對我國宇航員精神的肯定及其帶來的結果"使我們克服了所有的艱難險阻"，所以用一般過去時．
"正是我國宇航員的精神"，說明句子要表達的重點是"宇航員的精神"，因此句子需要一個強調句型，It was…that…句子強調的是主語．of our country 為一介詞短語作后置定語．
enable sb to do sth意為"使某人能夠做某事"；overcome意為"克服、戰勝"．

點評 強調句型可以強調除謂語以外的其它成分，如主語、賓語和狀語等．如：It was at the railway station that I met Li Ming yesterday．（強調地點狀語）
