限定性定语从句选连接词---表格
定语从句(1)
定语从句一．定语从句的定义：所谓定语从句，就是用一个句子来做定语来修饰一个名词，其中被修饰的名词叫做先行词，连接先行词和从句之间（或者说引导定语从句）的词语叫做关系词，关系词分为关系代词和关系副词。
其中常见的关系代词有：that,which,who,whom,whose,as,but,than;常见的关系副词有：why,when,where.（注意：what，how，whether，if和特殊疑问词+ever不能引导定语从句）。
二．如何选择定语从句的连接词：首先明确先行词是什么，然后找到后面的从句，把从句单独拿出来分析，看一看先行词在句子中做什么成分，根据语法选择连接词。
Eg:He tried to escape from the prison that/which was builtin the Middle Age .分析：1.找先行词：prison 2.把prison放入从句中可以看到prison在从句中是做主语，即the prison was built in the Middle Age .而在定语从句中能充当主语的连接词一般情况下是that和which，于是就能选出连接词了。
三．连接词的用法：1.that：可以修饰人和物，在从句中作主语或宾语,表语，做宾语的时候一般情况下可以省略。
Eg: She is a girl who/that has long hair.(在从句中做主语) Is this the news (that)/which you wanted to tell me yesterday?(在从句中做宾语，可以省略that)He is no longer a kind-hearted man that he used to be(在从句中做表语)注意：1）that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略，例如：His father died in the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。
限制性定语从句和非限制性定语从句的区别

.as 引导的从句可以放在句首，as 本身有“正如…..正象…”一类的含义。
与之连用的词有know，see，expect，announce，point out等。
此外，在the same…as…，such….as….中as引导的是限制性定语从句。

英语三大从句
英语三大从句LELE was finally revised on the morning of December 16, 2020复合句【语法要点】复合句是由一个主句加一个或几个从句所构成的句子。
从句只用作句子的一个成分，不能独立。
根据从句在句子中的作用，可分为名词性从句、定语从句和状语从句三类。
（一）名词性从句名词性从句包括主语从句、表语从句、宾语从句、同位语从句。
其关联词有连接词that、if、whether；疑问代词who、what、which和疑问副词when、where、how、why等。
1）if不能引导表语从句。
连接代词who、what、whose、which不能引导同位语从句。
2）有时as、as if/though、because也可以引导表语从句，能跟表语从句的谓语动词一般为系动词be、seem、look等。
例如：Things are not always as they seem to be.事情并不总是像表面上看来的那样。
It looks as if it were going to rain. It is because you eat too much.3）介词宾语不可以用which来引导，而要用what来引导。
例如：We can learn what we did not know. He will talk to us about what he saw in the .4）连词that引导的名词性从句除能用在except、but、in后之外很少作介词的宾语，。
其它一些介词的宾语从句如果由连词that引导，则需用it先行一步作形式宾语。
例如：He is a good student except that he is careless.You may depend on it that they will support you.5）若主句谓语动词是及物动词make、find、think、see、hear等，则把宾语从句置于宾语补足语之后，用it作形式宾语。
什么是定语从句
n 什么是定语从句？定语从句（Adjective Clause）是英语语法中的一个重要概念。
它是由一个从句构成的修饰性成分，用于进一步描述或限定某个名词或代词（被修饰词）的特征。
定语从句通常用于句子中作为定语，以提供更多的信息。
定语从句的构成：定语从句由一个引导词（关系代词或关系副词）和一个从句组成。
引导词在定语从句中充当连接词的角色，引导从句与被修饰词之间的关系。
常见的引导词有：who, whom, whose, which, that, where, when, why。
例子：- The girl who is sitting over there is my sister.（那个坐在那里的女孩是我的妹妹。
）- The book that I borrowed from the library is very interesting.（我从图书馆借的那本书非常有趣。
）在定语从句中，引导词的选择取决于引导从句所修饰的名词或代词的性质和在从句中所充当的角色。
下面是一些常见的引导词的用法和规则：- who/whom/whose: 用于修饰人，who作主语，whom作宾语，whose表示所有关系。
- which/that: 用于修饰人或物，which可作主语或宾语，that通常作宾语。
- where: 用于修饰地点。
- when: 用于修饰时间。
- why: 用于修饰原因。
定语从句的位置：定语从句通常紧跟在被修饰词之后，用于进一步描述或限定被修饰词的特征。
例子：- The house that is painted blue is mine.（那栋被涂成蓝色的房子是我的。
）- The girl who is wearing a red dress is my friend.（穿红裙子的那个女孩是我的朋友。
）需要注意的是，定语从句可以被省略或缩减，特别是当引导词在从句中作为宾语时。
这种情况下，引导词可以省略或缩减，并且从句的谓语动词可以改为不定式或动名词形式。
名词性从句的语态和连接词选择
名词性从句的语态和连接词选择名词性从句是英语中一种常见的句型，它可以作为主语、宾语、表语或同位语。
在使用名词性从句时，我们需要注意选择适当的语态和连接词来构建句子。
本文将探讨名词性从句的语态和连接词选择，以帮助读者更好地理解和运用这一句型。
一、名词性从句的语态选择名词性从句的语态通常有两种选择，即完成语态和不定式语态。
选择哪种语态取决于主句的时态和语义。
1. 完成语态当主句是现在时或将来时，并且名词性从句表示的动作发生在主句谓语动词之前时，可以使用完成语态。
例如：- It is important that the work has been completed before the deadline.- I insist that the assignment has been submitted on time.2. 不定式语态当主句是过去时，并且名词性从句表示的动作在主句谓语动词之后时，通常使用不定式语态。
例如：- He knew that he had to finish the project before Friday.- She realized that she needed to improve her English skills.需要注意的是，如果主句是过去时，但名词性从句表示的动作与主句谓语动词同时发生或在之前发生，也可以使用完成语态。
例如：- I realized that I had made a mistake.- He said that he had visited the museum yesterday.二、名词性从句的连接词选择名词性从句的连接词决定了从句在句子中的作用和语义关系。
常见的名词性从句连接词包括关系代词（who, whom, which, whose, that）、连词（that, whether）、副词（when, where, why, how）等。
