英语中六大从句用法总结


1、定语从句 定语从句所修饰的先 行词可以是名词或代词，
也可以是一个句子。定语从句通常位于先行词之后，由关系代词
或关系 副词引导。

关系词在从句中的成分修饰的先行词可否省略关系代词that
主语或宾 语人、物作宾语时可省略which主语或宾语物作宾语时
可省略who、whom、whose主语、 宾语和定语人作宾语时可省略关

点、原因一般可省略*限制性定语从句 限制性定语从句修饰先行
词，对先行词起修饰作用， 紧接先行词之后，无逗号，若省去，
原句意思不完整。引导定语从句的关系代词有
who,wh om,whose,which,that等。who,whom,whose用于指人，
whose有 时也可指物，相当于of which；which用于指物；that
既可指人也可指物，但只用于限 制性定语从句中。关系代词除了
引导定语从句，替代先行词外，还在从句中担任主语、宾语、定
语等。T he computers and cables which make up the
Internet are owned by people and organizations、 Those

形容词最高级修饰时，只能用关系代词that引导从句。T hat is
all that Ive heard from him、 Hes the first person that
Im going to interview this afternoon、2)关系代词的省略 在
从句中作宾语的关系代词常可省略。关系代词紧跟介词， 作介词
宾语时不可用that，只可用which或whom引导从句，并且不可省
略，但当介 词位于宾语从句句末时，作为介词宾语的关系代词仍
可用that，也可省略。T his is one of those things with
which we have to put up、 This is one of those things
(whichthat)
we have to put up with、3)引导定语从句的关系副词有
when, where,why等。关系副词在从句中作状语，意义上相当于一
个“介词+which”的结构。E ven in comic books where(=in
which)
there are no words,the stories are fully expressed
through the drawings、 No one knows the reason why(=for
which)

magnetism、 *“介词+whichwhomwhose”引导的定语从句 “介
词 +whichwhomwhose”可引导限制性定语从句，也可引导非限制
性定语从句，该结构中介词 的选择取决于从句谓语动词的固定搭
配，或先行词的习惯搭配。T his is the computer on which he
spent all his savings It is written by a person with whom
we are all familiar、 *as引导的定语从句 as引导的定语从句
主要用于“such、、、as”及“the same、、、as”的结构中，< br>代替先行词是人或物的名词。as引导非限制性定语从句时，代替

such problems as can be easily solved、(as代替先行词
problems)
As is mentioned above,no single company or group can
control what happens on the Internet、(as代替主语)
2、主语从句1）主语从句可直接位于主语的位置，如果从句
较长，谓语又较短，可用it作形 式主语，而将从句放在句末。常
见的句型有：
*It is a facta pitya questiongood news that、、、
*It seemsappearshappenedhas turned out that、、、 *It
is clearimportantlikelypossible that、、、 *It is
saidreportedestimatedhas been proved that、、、 It is

very useful、2)what引导的主语从句表示“、、、的东西时”，
一般不用it作形式主语。W hat we lack is experience、
3)what,who,when,why, whether等词含有各自的疑问意义，但它们
引导的主语从句，都用陈述语序。H ow the plan is to be
carried out should be discussed again、 I did know why I
felt like crying、
3、宾语从句1）宾语从句可位于及物动词、介词和某些形容
词后。连词that常可省略。介词后一般 接疑问词引导的宾语从
句。in that(因为),except that(除了),but that(只是）已构成
固定搭配，其他介词后一般不接that引导的宾语从句。*I
promised that I would change the situation、 *All this is
different from what American young people would say about
friendship、 *He is certain that watching so much
television is not good for children、 *This article is
well- written except that it is a bit too long、2）关于宾
语从句连词的选择：1 若从句来源于一个陈述句,那么,连词用
that,在口语中that可以省略;2 若从句来源于一个一般疑问句,
连词则用if 或whether;3 若从句来源于一个特殊疑问句,则连
词就是疑问词(如 what,who,where,when等)*They believe that
the computer will finally take the place of human
beings、(他们相信计算机终将代替人类。)
