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
并列句用分号（；）或连接词and, but来连接。
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 none of__________ is a dancer.
3.Mr Li has three daughters; __________ are doctors.
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.
He left the place where he lived for many years.
练习：
1.Rice doesn’t grow well _____ there is not enough water.
2.I still remember the farm_____ my parents worked ten years ago.
3. The visitor asked the guide to take his picture _____ stands the famous tower.
     A. that         B. where         C. which         D. there
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 on the morning of May 1st _____ I met John at the airport.
It is the morning of May 1st _____ I met John at the airport.
2. It is in the factory _______John works.
It is the factory _______John works.
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 computer _____you have.
2. She is such a kind girl _____all of us like to make friends with her.
3. It is such a good place _____everybody wants to visit _____it is well-known all over the world.
A. which; that B. as ; as C. as ;that D. that; as
五.  定语从句与习惯句型
注意固定句型：It is the first/second/third time that+ 从句（从句用现在完成时）
1.It is the first time ______she has been in Shanghai.
2.It was the time _______Chinese people had a hard life.
答案: 1.that 2.when
六、定语从句与单句
注意标点符号：两个单句间用句号，而定语从句两个句子间用逗号。
1.The mother told the lazy boy to work, ____didn’t help
2.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.  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。
it, as与what三种句型的转换
What is well known to us all is that the 2008 Olympic Games were a great success.（what连接的主语从句）
It is well known to us all thatthe 2008 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 2008 Olympic Games were a great success.（as引导的定语从句）
