強調句型
  這里講的強調句主要是以it為引導詞的分裂句。其構成形式為：It is (was) +被強調部分+ that(who, which) + 句子的其他部分。被強調的部分通常為主語、賓語和狀語。
  It is only when one is ill that one realizes the value of health.
  It is what you will do that is essential.

  Note:
  在被強調部分的后面，一般用that引出句子的其他部分。但是如果強調的部分是表示人的名詞，那么也可用who;如果是指物的名詞也可用which。
  It was Jane that/who lent me the money.
  It was this novel that/which they talked about last night.
  如果強調的是原因狀語從句，只能用because引導，不能由since, as或why引導。
  It was because(不用since或as) he had never had the opportunity that John hadn’t learned to drive.

  有三類句子成分不可以進行強調，即表語、謂語動詞和由though, although, whereas等引導的從句。
  It is although he is young that he can speak four languages. (誤)
  Although he is young, he can speak four languages. (正)
  It is whereas he prefers pop song that I like classical music. (誤)
  I like classical music whereas he prefers pop songs. (正)
