3. 考试技巧
语法填空解题策略
1. 确定定语从句关系词的解题要领:根据定语从句中所缺成分来确定是用关系代词还是关系副词。
2. 关系词应遵循“缺什么, 补什么”的原则
(1)如果先行词指人, 定语从句中缺少主语, 限制性定语从句中用wh/that; 非限制性定语从句中用wh。
(2)如果先行词指人, 定语从句中缺少宾语, 限制性定语从句中用wh/that/whm; 非限制性定语从句中用whm。
(3)如果先行词指物, 定语从句中缺少主语或宾语, 限制性定语从句中用which/that; 非限制性定语从句用which。
(4)如果先行词指时间或地点, 定语从句中缺少时间状语或地点状语, 则用when或where; 如果缺少主语或宾语, 则用that或which。
(5)在“介词+关系词”引导的定语从句中如果先行词指人, 则关系词用whm; 如果先行词指物, 则用which。
4. 知识点拓展
1：考点梳理
引导定语从句的关系词；
限制性与非限制性定语从句的区别；
“介词＋关系代词”的结构；
关系词之间的异同及选用。
考点1 定语从句的种类
(1)限制性定语从句
从句在句中是不可缺少的部分，去掉后主句意思往往不明确，与主句之间不用逗号隔开。
This is the huse which we bught last mnth.
(2)非限制性定语从句
从句是对主句或先行词的补充和说明，去掉后不影响主句的意思，与主句之间往往用逗号隔开。
The huse, which we bught last mnth, is very nice.
当先行词是专有名词或被物主代词/指示代词所修饰时，其后的定语从句通常是非限制性的。
Charles Smith, wh was my frmer teacher, retired last year.
My huse, which I bught last year, has gt a lvely garden.
非限制性定语从句还能将整个主句作为先行词，对其进行修饰，这时从句谓语动词要用第三人称单数。He seems nt t have grasped what I meant, which greatly upsets me.
考点2 关系代词与关系副词
考点3 关系代词that和which的特殊用法
1. 限制性定语从句中，只用关系代词that的情况：
(1)先行词是all, everything, anything, nthing, little, much, few等不定代词。
I will tell yu everything that I knw.
(2)先行词被序数词或形容词最高级修饰。
What is the first freign city that yu have ever been t?
(3)先行词被the nly, the very (正好), the last, all, any, every, n, little, much, sme等限定词修饰。
Chatting is the nly thing that interests her.
(4)先行词中既有人也有物。
The things and persns that they mentined are strange t me.
(5)在which或wh的特殊疑问句中含有定语从句。
Wh is the by that is lying under the tree?
2. 先行词指物时，只用关系代词which的情况：
(1)“介词＋关系代词”结构中。
The huse in which we live is very large.
(2)非限制性定语从句中。
He changed his mind, which made me angry.
(3)先行词本身是that。
What is that which yu have put int yur schlbag just nw?
考点4 限制性定语从句与非限制性定语从句的区别
考点5 关系代词as和which的区别
1. 位置不同。
as引导的定语从句可位于句首、句中、句末；which引导的定语从句不能位于句首。
As we all knw, life is nt a bed f rses.
Life is nt a bed f rses, which we all knw.
2. 意义不同。
as意为“正如，就像”，引导的从句表达人的观点、事物的习惯性等意义，主要起承上启下的作用；which意为“这一点”，引导的从句在意义上相当于一个并列句，补充说明主句的状态或结果。
As ften happened, they wn the ftball game again.
It rained heavily, which prevented us frm ging ut.
3. 当先行词被such, s, as等词修饰时，一般用as引导定语从句。
Such bks as yu want are sld ut.

3. 考试技巧
【关键技法点拨】
语法填空解题策略 名词性从句做题两步骤
第1步判断是否属于名词性从句;第2步判断名词性从句中的连接词;若从句中缺少主语、宾语或表语, 用连接代词; 若缺少状语就用连接副词; 如果不缺少成分则要考虑意思是否完整, 是否需要用whether/if; 如果不缺少成分且意思完整用that。

4. 知识点拓展
1：考点梳理
主语从句、宾语从句、表语从句的基本用法；
易混引导词的辨析；
名词性从句、定语从句和状语从句的区分。
考点1 基本用法
考点2 主语从句
1. 引导词
在复合句中充当主句主语的从句叫作主语从句。主语从句的常见引导词有：
(1)从属连词： that, whether, if
(2)连接代词：what, which, wh, whse, whm, whatever, whichever, whever, whmever
(3)连接副词：hw, when, where, why, hwever, whenever, wherever
2. it作形式主语
在通常情况下，that引导主语从句时，常用it作形式主语，而将that从句置于句尾。用it作形式主语通常有以下四种句型：
(1)It＋be＋形容词＋从句：
It is necessary that... 有必要……
It is imprtant that... 重要的是……
It is bvius that... 很明显……
(2)It＋be＋过去分词＋从句：
It is believed that... 人们相信……
It is knwn t all that... 众所周知……
It has been decided that... 已决定……
(3)It＋be＋名词(短语)＋从句：
It is cmmn knwledge that... ……是常识
It is a surprise that... 令人惊奇的是……
It is a fact that... 事实是……
(4)It＋不及物动词/动词短语＋从句：
It appears that... 似乎……
It happens that... 碰巧……
It ccurs t sb. that... 某人突然想起……
It desn’t matter whether... ……没有关系
考点3 宾语从句
考点4 表语从句
1. 引导词
在复合句中充当表语的从句叫作表语从句，可接表语从句的连系动词有be, seem, lk, sund, taste, feel, remain, appear等。表语从句的常见引导词有：
(1)从属连词： that, whether
(2)连接代词： what, which, wh, whse, whm, whatever, whichever, whever, whmever
(3)连接副词： hw, when, where, why
2. 几种特殊的表语从句
(1) as if/thugh 引导的表语从句
此类表语从句常出现在seem, lk, sund, taste, feel, appear等连系动词后，从句可用陈述语气，也可用虚拟语气。
It sunds as if yu are frm Canada.
It seemed as if she had heard the news.
(2) because和why引导的表语从句
此类表语从句常用于以下句型：
this/that is why... 这/那是……的原因
this/that is because... 这/那是因为……
注意：主句主语是reasn时，表语从句一般由that引导，而不用because或why。
The accident that happened yesterday was because the driver had been drunk.
The reasn fr yesterday’s accident is that the driver was drunk.
考点5 同位语从句
考点6 连词whether和if在名词性从句中的使用
1. 用whether或if均可的情况
(1) whether可引导各种名词性从句。引导大部分动词后的宾语从句时，两者均可。
(2) it作形式主语，且主语从句在句末时，两者均可引导主语从句。
It hasn’t been decided whether/if we shall study abrad.
2. 用whether而不用if的情况
(1)主语从句和宾语从句置于句首
Whether we will g camping depends n the weather.
Whether he will succeed, I can’t say.
(2)引导表语从句和同位语从句
The questin is whether we can get in tuch with him.
He must answer the questin whether he will attend the meeting.
(3)引导介词的宾语从句
Everything depends n whether we have free time.
(4)引导词与r nt连用
He desn’t knw whether r nt he is ging t stay.
(5)引导词后接t d
They needed mre time t cnsider whether t hld a meeting.
(6)有些动词如discuss, decide等后的宾语从句
We discussed whether we shuld hld a meeting.
(7)避免用if引导产生歧义
Let me knw whether yu are cming t ur party.
