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.
