定语从句和其他易混句型区别及典型练习

定语从句和其他易混句型区别及典型练习定语从句和其他易混句型对比和区别一．定语从句与并列句 1.并列句用分号（；）或连接词 and, but 来连接。

2.定语从句用关系词来引导关系词具有两个作用：一是放在先行词与定语从句之间起连接（主句和从句）作用二是充当从句中的一个成分。

练习：1.Mr Li has three daughters, none of________ is an engineer.2.Mr Li has three daughters, but noneof__________ is a dancer. 3.Mr Li has three daughters; __________ are doctors. 二二.定语从句与地点状语从句 1. where 引导的定语从句用来修饰表示地点意义的名词或代词可以改成“介词+which”。

2. where 引导的地点状语从句用来修饰动词表示动作发生或存在的地点不可改成”;介词+which”。

3.做题时先根据句意确定有无先行词。

如有是定语从句如无是状语从句。

对比下面两个句子：He left the key where he had been an hour ago.

The visitor asked the guide to take his picture _____ stands the famous tower.A. thatB. whereC. whichD. there 三三. 定语从句与强调句 1.强调句型可以还原成正常语序的句子也就是说强调句型中去掉 It be... that 后句子仍然通顺意义也依然完整只是没有那么强调突出。

而定语从句去掉了 It be... that 后句子就不完整了。

2.强调句型常常与定语从句混合使用。

Could it be in the restaurant in which you had dinner with me yesterday that you lost your handbag? It is in Qingdao you"re going to pay a visit to that this kind of washing machine is produced. It was in Beihai Park where they made a date for the first time that the old couple tole us their love story. 练习; 1.

It is the factory _______John works. 四四.定语从句与结果状语从句 1. such/the same--- as 中as 是关系代词其后句子不完整as 在从句中充当成分（主、宾或表语）。

2.such---that 结果状语从句中其后句子是完整的that 只起连接作用。

对比下面两个句子：He is such a good teacher as we all love and respect.He is such a good teacher that we all love and respect him. 练习：1.I have the same puter _____you have.2. She is such a kind girl _____all of us like to make friends with her.3.

1.The mother told the lazy boy to work, ____didn��t help2.The mother told the lazy boy to work._____didn��t help. 练习：There are 56 students in our class, most of ____are girls. 七七.各各句型之间的异同（一）定语从句与同位语从句的区别 1.that 连接同位语从句：放在抽象名词（news, idea, fact, suggestion, advice, hope 等）之后表明抽象名词的具体内容（中间加 be 可帮助理解）。

同位语从句句子本身成分完整that 无意义只起连接作用不在从句中作任何成分不能省略也不可用which 代替。

2.that 引导定语从句：定语从句句子不完整that 是关系代词它在从句中不但起连接作用同时在从句中作某一成分（主语、宾语或表语）作宾语时可省略指物时还可用 which 替换指人时常可用who 代替。

（二）强调句型与主语从句的区别强调句型中去掉 It be... that 后句子仍然通顺意义也依然完整只是没有那么强调突出。

主语从句的复合句中的 it 是指示代词后面多为系表结构或被动语态。

如果去掉 It be...that句子就不通顺了。

（三）it, as 与 what 三种句型的转换 What is well known to us all is that the 20__ Olympic Games were a great success.（what 连接的主语从句）It is well known to us all thatthe 20__ Olympic Games were a great success.（形式主语 it 引导的主语从句）As is well known to us all, the 20__ Olympic Games were a great success.（as 引导的定语从句）练习：1.The news ______came from the front was true.2.The news ______he won the game was true.3.She was not ______she used to be.4.The city is no longer a place _____ it used to be.5._____ is known to us all, paper was first made in China.6._____ is known to us all that paper was first made in China.7.
