高中英语 语法精讲（Unit 19　Modern agriculture）人教版

　　语法精讲The Use of “It” (2) for Emphasis “It”的用法(2)表示强调

　　强调结构：It is/was+被强调部分+that/who+句子剩余部分。强调结构可用来强调除谓语之外的所有成分：主语、宾语、状语等。应注意以下方面：

　　1.强调主语用主格，强调宾语用宾格。

　　It was I that met Tom in the park.

　　It was him that I met in the park.

　　2.只有强调人的时候可用who,其余的一律用that,不管强调的是时间、地点还是原因、方式。

　　It was in Shanghai that I saw the film.

　　3.若把强调结构中的“It is/was...that/who...”去掉，仍为一个完整句子，因此应注意状语的完整性，一定不要丢掉了必要的介词。

　　It was in 1975 that I worked in the factory.

　　4.若强调主语，从句的谓语动词应与被强调的主语一致。

　　It is Prof.Lin who teaches us English.

　　5.注意强调结构与定语从句的区别。

　　It is the factory where I worked 30 years ago.(定语从句)

　　It is in the factory that I worked 30 years ago.(强调结构)

　　6.注意not...until的强调：把not与until一并提前。

　　It was not until his mother came back that he went to bed.

　　7.注意强调结构的疑问形式。

　　Was it in the room that we held a meeting?

　　When was it that you saw him for the first time?
