(关于英语语法的问题,我们是这样认为的:语法不是万能的!而且,要想讲流利的英语,也不是一定要精通语法才行,语法千变万化,每一天都会改变,只要人民改变了说话的习惯,语法也就相应的必须改变了,语法是由人们创造的,而不是由语法家创造的!何况,以英语为母语的人,又有几个是精通语法的呢?当你问他们为什么英语要这么讲时,他们只能告诉你,“我们天生就是这么讲的,That comes naturally!”。我们真的很希望大家最后能达到那样的境界,就是把英语变成一种习惯,这才是学英语的最高境界!希望大家早日突破英语语法关!)

13.3 强调句结构

  常考的强调句结构是it 引导的句子。
  It is (was) 被强调部分+ that (who) + 句子其他部分。

  此结构强调的成分仅限于主语,宾语和状语。
   It is from the sun that we get light and heat.
   It was not until I had read your letter that I understood the true state of affairs.


典型例题
1) It was last night ___ I see the comet.
A. the time B. when  C. that  D. which
  答案C. 强调句的结构是: It +be +强调部分 + that (who) + 主谓句。 强调句的连词只有两个,that和who。当强调的部分是人,且为句子的主语时,才用 "who",其余用that。

 原句: My father did the experiment in the lab yesterday evening.
 强调主语: It was my father who did the experiment in the lab yesterday evening.
 强调宾语: It was the experiment that my father did in the lab yesterday evening.
 强调时间: It was yesterday evening that my father did the experiment in the lab. (注意不用when)
 强调地点: It was in the lab that my father did the experiment yesterday evening.

2)It is ten years ___ Miss Green returned to Canada.
A. that B. when  C. since  D. as
  答案C. 考点是连词用法。 本题易误选为A. that. 其实本句不是强调句。若是,去掉It  be… that还应是一个完整的句子。而本句去掉 'It is…that',只剩下ten years Miss Green returned to Canada. 不成句。因此本句不是强调句。
  It is /was +时间+ since… 其中is<---> has been  was <---> had been.
