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, whate ver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, appreciat e, 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 are 20 people in the bu s, most of ________ are boys.
b. There are 20 people in the bus, most of ________boys.
c. There are 20 people in the bu s and most of _______ are boys.
key: whom/ them/them
* 比较：
a. ______ is known to us all, th e 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 tha t 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 st udents 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 pos sible.
b. Rose is such a kind girl ____ __ she has won a high reputation in o ur 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, i n 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
