高考英语三大从句复习

高考英语三大从句复习

一、专题详解

一、名词性从句解题技巧

1.正确分析句子成分是做对题的关键。

2.连接词的特点：

that没有意义，在从句中只起连接作用，不充当句子成分；

whether,if表“是否”，在从句中只起连接作用，不充当句子成分；

what,which,how,where,when,whatever等，有各自的意义，在从句中担任成分。

3.that引导主语、表语、同位语从句时不省略；有多个that引导的宾语从句时，只有第一个that可省略；引导的宾语从句中含有从句时，也不省略。

4.介词后一般不接that引导的宾语从句，此时需要用it作形式宾语；某些动词enjoy,hate,have,like,love,appreciate,take也不能接that引导的宾语从句，此时需要用it作形式宾语。如：You may rely on it that he will come on time.

5.reason做主语时，表语从句只能用that引导。

6.doubt在肯定句中其后的宾语从句常用whether,if引导；doubt在否定和疑问句中其后的宾语从句常用that引导。

如：There is some doubt___whether_______he will come tomorrow.

7.与if相比较，whether引导所有名词性从句，也可用于连接介词后的宾语从句，可以discuss,decide后引导宾语从句，还可与or not连用。

二、定语从句解题技巧

1.正确分析句子成分是做对题的关键。

2.引导词的特点：

*关系代词：which,that,who,whom,whose；关系副词when,where,why和that。（略）

*that既指人又指物，先行词是everything,all等或有the first,the most,the very等修饰时都能用，所以一般情况下用that引导定语从句比较保险，但以下情况不能用，切记： a.在非限制性定语从句中（从句前面有逗号与主句隔开），用which或who,whom; b.前面有介词时，用which或whom;

c.前面的先行词是anyone,those时，用who；

*as和which可以引导非限制性定语从句，指代整个句子（which有时也仅仅指代主句的一

个词和一部分）。which引导的这种从句只能放在主句后，as引导的这种从句可以放在主句前、后、或在中间插入。另外，以下短语几乎成为固定搭配：

as is often the case,as is known to all,as is hoped,as is natural,as is reported,as has been said,as we know。

*当先行词为case,situation,condition,point时，且从句不缺少主要成分，用where引导；而

出现occasion常用when;

*比较：

a.There are20people in the bus,most of________are boys.

b.There are20people in the bus,most of________boys.

c.There are20people in the bus and most of_______are boys.

key:whom/them/them

*比较：

a.______is known to us all,the earth goes around the sun.

b.______is known to us all is that the earth goes around the sun.

c.______is known to us all that the earth goes around the sun.

Key:As/What/It

*比较：

a.He is one of the students who_____(praise)by the teacher.

b.He is the only one of the students who______(praise)by the teacher.

Key:were praised/was praised

*比较：

a.Rose is such a kind girl______will surely give others help if possible.

b.Rose is such a kind girl______she has won a high reputation in our class.

Key:as/that

三、状语从句和连词解题技巧

1.熟悉状语从句的分类，熟悉每个连词的语义和语用特征，尤其是：as,since的灵活运用；before,until,unless,while,as,if,in case这些难以区分的词。

2.区分常用的含时间状语的句型，如It’s/It has been+一段时间+since…;It is/was+具体时间+when…;It will be/was+一段时间+before…;It is/was+时间状语+that…

3.before sb.knew it(不知不觉)Before I could say a word(还来不及说什么)before long(不久以后)

4.be on the point of doing…when…;be about to do…when…;be doing…when…;had just don e…when…
