高一英语语法强调句课件高一英语语法强调句课件一、强调句句型1. 陈述句的强调句型:It is/ was + 被强调部分(通常是主语、宾语或状语)+ that/ who(当强调主语且主语指人)+ 其他部分。
e.g. It was yesterday that he met Li Ping.2. 一般疑问句的强调句型:同上,只是把is/ was提到it前面。
e.g. Was it yesterday that he met Li Ping?3. 特殊疑问句的强调句型:被强调部分(通常是疑问代词或疑问副词)+ is/ was + it + that/ who + 其他部分?e.g. When and where was it that you were born?4. 强调句例句:针对I met Li Ming at the railway station yesterday.句子进行强调。
强调主语:It was I that (who) met Li Ming at the railway station yesterday.强调宾语:It was Li Ming that I met at the railway station yesterday.强调地点状语:It was at the railway station that I met Li Ming yesterday.强调时间状语:It was yesterday that I met Li Ming at the railway station.5. 注意:构成强调句的it本身没有词义;强调句中的`连接词一般只用that,who,即使在强调时间状语和地点状语时也如此,that,who不可省略;强调句中的时态只用两种,一般现在时和一般过去时。
原句谓语动词是一般过去时、过去完成时和过去进行时,用It was ,其余的时态用It is .二、not until 句型的强调句1. 句型为:It is/ was not until + 被强调部分 + that + 其他部分e.g. 普通句:He didnt go to bed until/ till his wife came back.强调句:It was not until his wife came back that he went to bed.2. 注意:此句型只用until,不用till.但如果不是强调句型,till,until可通用;因为句型中It is/ was not 已经是否定句了,that后面的从句要用肯定句,切勿再用否定句了。
It is that/who 强调句句型用法详解_用法辨析当需要强调句中的主语、宾语、状语时,我们常用It is/was+被强调部分+that/who...这样的句型,被强调的部分放在前面,其它部分置于that之后。
强调的主语如果是人,that可以换用who。
如何区分这种强调句句型与that从句?如果把这种句型中的句型结构部分(It is/was...that/who...)划掉后,是一个完整无缺的句子即是强调句。
He read three books in the library yesterday.我们分别可以强调主语、宾语、地点状语和时间状语。
如:It was he who(that)read three books in the library yesterday.(强调主语)It was three books that he read in the library yesterday.(强调宾语)It was in the library that he read three books yesterday.(强调地点状语)It was yesterday that he read three books in the library.(强调时间状语)在使用It is/was...that/who...强调句型时应注意以下几点:1、当被强调部分指人时,可用that,也可以用who;指物时,只能用that,如:It was Tom who(that)I met last week.我上周遇见的就是汤姆。
It is a new boke that his brother wants to buy.他的弟弟就想买一个新博客。
2、强调状语时,只有that,不用when、where,如:It is at 5 o’clock that the train will arrive. 五点钟是火车到达的时间。
