2017届高考英语（课标全国）一轮复习课件：语法突破第11讲

　　good deeds for the old lady. It is only I who/that am willing to go to see the film. 种类要点归纳典句示例强调句如果原句的谓语动词是现在时或将来时，强调句结构须用：It is...that/who...；如原句的谓语动词是过去时态，则其结构须用It was...that/who... It was I who saw him in the street yesterday afternoon. What is it that you want me to do？ “not...until...”句型的强调结构为“It is/was not until...that...” It was not until the last operation was finished that Bethune left the battle hospital. 强调句的特殊疑问句型为：疑问词＋is/was＋it＋that/who...？ Where was it that you met Jack yesterday？特别提醒：强调句与其他从句的区别强调句型要注意和it代表时间、距离、温度、自然现象、具体事物或人物等时所构成的各种句型的区别。判断是否是强调句，可采用“还原法”，即把“It is/was...that/who”去掉。如果还原为一般句式后，句子各种成分完整，则是强调句，否则不是。种类要点归纳典句示例谓语动词的强调 do/does/did＋动词原形 Do come on Sunday. He did finish the task completely last week. 1.强调句与定语从句的区别：定语从句中that是充当从句的成分的，而在强调结构中，that无任何意义。 It was in the park that Tom lost his watch.(强调结构，that无意义) 汤姆是在公园里丢的那只手表。 It was the street that he took a photo of.(定语从句，that充当从句中of的宾语) 他就是给这条街照的相。 2.强调句与主语从句的区别：it作形式主语，that引导真正的主语从句，去掉it be和that句式不完整。若为强调句式，去掉之后句式完整。 It is a fact that he is an honest man.(主语从句) 他是一个诚实的人，这是事实。 It is he that is an honest man.(强调句) 诚实的人是他。 3.强调句与状语从句的区别：尤其出现“it be＋时间”时，一定要区分是强调句还是时间状语从句。 It was eight o’clock when he came back.(时间状语从句) 当他回来时已经8点了。 It was at eight o’clock that he came back.(强调句) 就在8点钟他回来了。
