英语_强调句的有关知识
强调句的有关知识1.定义：强调句型是通过it强调词来改变句子结构，使句子的某一成分受到强调而构成的强调结构2、基本结构:(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）+ 其它部分。
强调句可以强调除谓语以外的一切成分。
下面我们针对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.(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 my old friend?(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 + 其它部分？e.g. When was it that you were born?我们需要注意的是：第一、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。
第二、It's ....that/who....的强调句型只是为了强调某一成分，而不充当成分。
所以它和It 作形式主语，真正的主语从句后置的情况有所不同。
强调句型用法讲解与练习
强调句型是英语中常用句子结构，又是高考中的常见考点，其基本结构为：It + be+ 被强调部分＋that＋句子其余部分。
现将其用法归纳如下:1. 强调句型中，能够被强调的句子成分通常为主语、状语、宾语等，不能用来强调谓语动词、表语、补语、让步状语、条件状语等。
例如It was in the park that I met my old teacher yesterday. (强调地点状语)It is Mr. Smith that thinks Tom is a clever boy. （强调主语）2．强调句型中，连接词一般用that，如被强调的部分是人，也可用who/whom，其他一律用that，不能用which, where, when等，即使被强调的是物、时间状语或地点状语。
例如It was at the gate that we met the inspectors this morning.It is our head-teacher that/ who/whom we often turn to for help.3．强调结构中，无论被强调的是人还是物，单数还是复数，be动词一律用单数is/was 形式，如果原句的谓语动词是一般过去时，就用was; 是一般现在时，就用is。
也可以用"情态动词＋be"形式。
例如It was the farmers that lived a hard life before liberation.It might be yesterday that John bought a book for Mary.４. 强调句型也有疑问句形式，包括一般疑问句、特殊疑问句和反意疑问句。
一般疑问句的强调形式，只需将is/ was 提前，移至句首即可，即：Is/ Was it … that …。
特殊疑问句的强调形式，须将陈述句变成一般疑问句，再在句首加上疑问词，即：疑问词（被强调部分）＋is/was + it + that + 句子其余部分。
强调句型
强调句强调句结构为：It is(was) ＋被强调部分＋that(who)＋其他成分，此结构强调的成分仅限于主语，宾语和状语，不能是定语或谓语，强调人时可用who 或that作连词，强调其他成分用that。
1．强调的成分(1)强调主语：句子的谓语动词和被强调的主语保持一致。
It was he who(that) read three books in the library yesterday.是他昨天在图书馆里读了三本书。
It is they that were late.他们迟到了。
It is I who (that) am to blame. 是我应该受责备。
(2)强调宾语It was a Canadian that/whom Mary met in the park last Sunday.玛丽上周日在公园里遇到的是一位加拿大人。
(3)强调状语：状语既可以是短语也可以是状语从句①强调时间，地点或方式状语时，要用that，不能用when，where 或how等。
It was in the library that he read three books yesterday.昨天他是在图书馆里读的三本书。
It was last Sunday that Marry met a Canadian in the park.玛丽是上周日在公园里遇到了一位加拿大人。
②强调原因状语从句，从句只能用because 引导，不能由since，as或why引导。
It was because he was ill that he couldn’t come to school.正是因为他病了，他才没来上学。
③对not... until... 句型的强调结构为It is not until...that...，that后面从句用肯定形式。
It was not until the rain stopped that I went home.直到雨停了我才回家。
辨别强调句、定语从句、主语从句、状语从句
辨别强调句、定语从句、主语从句、状语从句（要点精讲）一、强调句与各从句的比较1．强调句与主语从句的比较强调句将句子中的It is/was … that同时省去，句子仍然成立；而主语从句不能。
如：(1)It was Tom that saw Jane at the movie theater yesterday. 是汤姆昨天在电影院见到简。
本句若将It was及that同时省去为：Tom saw Jane at the movie theater yesterday. 句子同样成立，因此该句是强调句。
(2)It is true that he is a man of few words.本句若将It is及that同时省去为：true he is a man of few words.，显然句子错误，因此，该句不是强调句，而是主语从句。
2．强调句与定语从句的比较(1)强调句中的It没有实际意义，It be与that同时去掉后句子仍然成立；而定语从句中的It be与that不可同时省略。
(2)在强调句中连接词只有that、who，并且不可以省略；而在定语从句中一般使用关系代词that，which，who，whom或关系副词when，where，why等，而that在从句中作宾语的时候可以省略。
(3)强调句中可以用副词、介词短语或从句来作被强调的内容；而定语从句的先行词（中心词）一般是名词或名词短语。
比较下列句子①It is on the island that they spent 10 years.②It is the island where (on which) they spent 10 years.解析：①表示地点的名词the island前有介词与其连用，说明它是一个完整的地点状语。
如果将it is及that去掉：They spent 10 years on the island.它的意义仍然完整。
