高中英语语法,it is 的强调用法

　　1.一般情况用It is(was)……that…,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.(强调时间状语)
　　2.当被强调部分指人时,可用that,也可用who；指物时,只用that,如：
　　3.强调状语时,只用that,不用when、where.如：
　　4.被强调的部分是主语时,注意句子的谓语动词和被强调的主语保持一致.如：
　　It is he who is late.　It is they that were late.
　　5.一般疑问句的强调句为“Is (was) it that…?”；特殊疑问句为：“特殊疑问词 is (was) that…?”结构.如：
　　Was it ten years ago that his father died?（他的父亲是十年前去世的吗?）
　　When is it that you will set off?（你到底什么时候出发?）
　　6.“not…until…”句型的强调结构为“It is not until…that…”应注意把否定词not转移到until前面.如：
　　I didn't go home until rain stopped.(直到雨停了我才回家).
　　强调句为：It was not until rain stopped that I went home.
　　强调句去掉It is.that ,还原一下次序,句子依旧完整.
祝开心~!这有一道题it is these products___can cause the flu.A.thatB.which C.WhatD.how 选哪个选A，强调句型。 因为 These products can cause the flu去掉强调句型依旧完整。如果满意，采纳吧，谢谢(*^__^*) 嘻嘻that 后面是都可以加完整的句子和不完整的句子吗如果去掉that完整，就是强调句型。如果去掉不完整，就是定语从句It is she that makes my heart broken.强调句型She is the one that makes my heart broken.定语从句
