复合关系代词+准关系代词

-复合关系代词的种类

复合关系代词=先行词+关系代词

代替人:whoever,whomever

代替人或物:whichever

代替物:what,whatever

whoever=anybody who

anybody为代词,可在主句中当作主语或宾语,who做主语引导定语从句修饰anybody

注:whoever作副词连词时,等于no matter who(与主句中间有逗号相隔)

whomever=anybody whom

anybody在主句中只能做宾语,whom作宾语引导定语从句修饰anybody

whichever=any one which/who (三者以上 同一类的任何一个...)

whichever=either which/who (二者 同一类中的任何一个...)

what=the thing(s) which(所...的东西)

造句注意原则:

a.前面不可有先行词

b.what视为the thing(s) which

c.which在所引导的定语从句中可做主语、宾语或be动词后的表语

whatever=anything which(...的任何东西)

注:whatever作副词连词时,等于no matter what(与主句中间有逗号相隔)

whatever(不同类的任何东西)  VS  whichever(同一类的任何一项)

what  (所...的东西)VS  whatever(所...的任何东西)

however

连接性副词:然而

副词连词:无论如何 = no matter how

造句步骤:

a.how=no matter how

b.造含有形容词或副词的句子

c.将句子置于no matter how之后

d,将形容词或副词移位在how之后,形成状语从句,再接主句

特殊句型:

However poor he is,he doesn't want anyone to help him.

=However poor he may be,he doesn't want anyone to help him.

=Be he ever so poor,he doesn't want anyone to help him.

-准关系代词的种类&形成条件

种类:than,as,but

形成条件:than,as,but之前若有名词

than=than+the+前面名词+关系代词

than视为关系代词,在所引导的从句中作主语、宾语或be动词之后的表语

as=as+the+前面名词+关系代词

as若做准关系代词,只用于下列短语中:

such+n.+as(像...那样的...)

the same+n.+as(和...相同的...)

as+adj.+n.+as(和...一样的...)

注:such+n.之后绝不可用like加以修饰

the same...as...  VS  the same...that...

the same...as... 和...相同的...(两个人或物)

the same...that... 就是同一个...(一个人或物)

as单独使用,可作关系代词=which,用以代替整个主句

要点:

as引导的从句可置于主句的前后,which引导的从句则只能置于主句之后

as+be+被动语态时,be动词可以省略

特殊用法:as usual,as follows

下列短语中,若置名词,只能置单数可数名词

so...that...(如此...以致...) 注:such...that...可置任何名词

as...as...(和...一样的...)

too...to...(太...而不...)

how...(多么地...) 注:what之后可接任何名词

以上短语与下列表数量的形容词连用时,可不必与单数可数名词连用

many(许多的)/ few(少量的)+复数名词

much (许多的)/ little(少量的)+不可数名词

but只用于no+n.之后,此时but=who/whom/which/(that)...not

There is no+名词+who/whom/which/(that)...not

=There is no+名词+but...

注:定语从句中有do,does,did等助动词时,要先去掉do,does,did,再依时态、人称将之后的动词还原
