高中英语从句语法总复习TYYGROUP system office room 【TYYUA16H-TYY-TYYYUA8Q8-定语从句常考知识在复合句中修饰名词或代词的从句叫定语从句。

被修饰的名词或代词叫先行词。

通过从句的意思判断先行词。

引导定语从句的关系代词有who，whom，whose，which，that等和关系副词where，when，why等。

一、非限制性定语从句记：有逗号的从句，连接词一定不用that。

典型例题They will fly to Washington,_________ they plan to stay for two or three days.二、关系代词who，whom，whose引导的定语从句这类定语从句中，who在从句中用作主语，whom从句中用作宾语，whose从句中用作定语注意：Whose既可代表人，也可代表物eg：Do you see the house whose windows are all broken?三、关系代词that和which引导的定语从句1、只能用which的情况（1）介词+which（2）非限制性定语从句2、只能用that的情况（1）先行词为不定代词（all，nothing，much等）（2）两个the：先行词为序数词和最高级（3）人和物同时做先行词时（4）先行词被the only，the very修饰时3、“介词+which/whom”中介词的选择关系代词前的介词使用时根据与名词前面的动词搭配关系和介词的搭配关系及句子结构上的需要而定。

eg：We`ll never forget the day on which we went camping.四、关系副词when，where，why引导的定语从句1、when，where，why=介词+which，有时为表达清楚，还可在关系副词where、when前加介词from，to。

Reason Why= reason for which2、关系副词和关系代词的比较记：从句的句子是完整的连接词一定用关系副词3、高考对关系副词where的考查高考中对where的考查趋于复杂，先行词由“明显的地点”转为“地点的模糊化”。

Where 不能只理解为表地点，当先行词表示某人/物的处境（situation），或某事所发展的阶段，或表达某事的某个方面（part，point）时都可用where这个关系副词。

例词：Place地点 Case案例 Situation形势 Point点 Top顶点 Position地位Stage阶段 Occasion场合 Aspect方面…….五、关系代词as，which的区别As主要用于as…as；the same as…；such as…等结构中。

译为“正如”。

as 引导非限制性的定语从句，修饰前面整个句子，而which均可。

eg：The meeting,which was held in the park,was a success.eg：The meeting was a success,as was expected.典型例题（1）My friend showed me round the town, was very kind of him.A. whichB. thatC. whereD. it（2）The Beatles，________ many of you are old enough to remember,came from Liverpool.六、way的特殊用法The way that/which/不填 he explained to us was quite simple.The way that/in which/不填 he explained the sentence to us was not difficult to understand.考点剖析命题规律：（1）关系代词的辨析及关系副词的辨析。

（2）关系代词的指代情况（3）定语从句的主谓一致问题。

例题：规律总结：定语从句一般考连接词，一般分三步完成。

1、判断定语从句的先行词和理解从句意思。

2、看从句是否完整，完整一定用关系副词。

3、不完整的……（1）*关系代词和关系副词的辨析，判断从句是否完整，完整的连接词一定用关系副词。

eg：This is the farm where he works.eg：This is the farm which he visits.*遇到situation，part，point，place，period等，一般连接词用where。

遇到time，age，day等，一般连接词用when。

*介词后一定不加that，注意介词的判断。

介词+which/whom（不用who）。

关系副词=介词+which（2）*非限制性定语从句及有逗号的从句，一定不用that（特别注意先行词为整个句子时）。

*which，that的一些特殊用法。

*作宾语的关系代词可省略（3）定语从句的两个特殊句型*Is this school we visited that year?Is the school we visited that year?Is this the school we visited that year?名词性从句常考知识一、名词性从句的结构和功能总述名词性从句包括主语从句、宾语从句、表语从句、同位语从句。

名词性从句主要有四种从句结构：以that引导的从句；以whether/if 引导的从句；以特殊疑问词引导的从句；以what或wh-ever等连接代词引导的名词性关系从句。

主语从句宾语从句表语从句同位语从句作及物动词宾语作介词宾语that 一般不省略可以省略一般不省略一般不省略一般不省略whether/if（是否）放于句首时只用whether 用whether/if均可，但有区别只用whether 只用whether 只用whether特殊疑问词注意语序要用陈述语序名词性关系从句注意语序要用陈述语序典型例题（1）Can you tell me ________________(我如何去)get to the railway station?（2）These photographs will show you _____________________________(我们村上看上去是什么样子的)。

二、that从句(一)主语从句1、that从句作主语时，常用it作形式主语，常见的句型有：（1）It+be+形容词(obvious,true,natural,surprising,good,wonderful,funny,possible,likely,certain,pr obable…)+that从句。

eg：It is certain that she will do well in her exam.（2）It+be+名词词组（no wonder,an honor,a good thing,a pity,no surprise…）+that 从句。

eg：It`s a pity that we can`t go.（3）It+be+过去分词（said，reported,thought,expected,decided,announced,arranged…）+that从句。

在可以接复合宾语的动词之后，如think，make，consider等，可用it做形式宾语。

eg：He has made it clear that he will not give in.eg：We consider it necessary that he should improve his pronunciation.2、that从句一般不能充当介词宾语，但可作except，in等介词的宾语。

其他介词后需用that时，必须用it作形式宾语。

eg：You may depend on it that I shall always help you.（三）表语从句that引导表语从句时，不可省略。

eg：My decision is that all of us are to start at 6 o`clock tomorrow morning.（四）同位语从句连词that引导的同位语从句，在从句中不担当任何成分，不省略。

应在某些有内容的名词之后，如：fact，hope，desire，thought，suggestion，idea，news，problem，possibility等。

eg：There`s a feeling in me that we`ll never know what a UFO is—not ever.三、whether/if（是否）（一）在表语从句和同位语从句中只能用whether不能用if；当主语从句放于句首时，也只能用whether不用if；当it作形式主语，主语从句放在句末时用whether或if均可。

eg：Whether the meeting will be given is still a problem.eg：It is doubtful whether/if he will come here.eg：The problem is whether the meeting will be given.eg：I have no idea whether the meeting will be given.（二）在宾语从句中：介词后只用whether，不用if。
