宾语从句的使用方法宾语从句的讲解
宾语从句是主从复合句中最常见的从句之一。 它作及物动词、
介词或者某些形容词的宾语。由于宾语从
句涉及到引导词、语序、时
态等多方面的内容,所以宾语从句的用法一直是学习的重点难点。对
宾语从句的用法进行了详尽讲解并附有例句,望对中学生朋友有所帮
助。
置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾
语从句的语序必须是陈述语序。谓语动词、
介词、动词不定式,v.-ing
形式后面都能带宾语从句。有些形容词(afraid,sure,g
lad等)之后
也可以带宾语从句。
在复合句中作主句的宾语,引导词有:
连词:that (that
常可省略),whether, if
代词:who, whose,
what ,which
副词:when ,where, how,
why 等。
(一)that引导的宾语从句(在非正式场合that可以省略)
可跟that从句做宾语的动词有:
say, think, insist, wish, hope, demand, imagine,
wonder,
know, suppose, see, believe, agree,
admit, deny, expect,
explain, order, mand,
feel, dream, suggest, hear, mean, notice,
prefer, request, require, propose, declare,
report等。
例句:The boy believes
that he will travel through space
to other
plas.
注意事项:当主句谓语动词是 think,
believe, suppose,
expect
等词,而宾语从句的意思是否定时,常把否定转移至主句表
示。
例句:I don’t think it is right for him to treat you
like
that.
在以下情况中that不能省略
当句中的动词后接多于两个由that引导的宾语从句时,第一个
that可省,但后面的that不可省。
例句:He
said (that) you were too young to understand the
matter and that he was asked not to tell you.
当主句的谓语动词与that宾语从句之间有插入语时,that一
般不可省。
例句:Just then I noticed, for the first
time, that our
master was wearing his fine
green coat and his black silk cap.
当that从句是双宾语中的直接宾语时,that不可省。
例句:I
can’t tell him that his mother died.
注意事项:许多带复合宾语的句子,that引导的宾语从句经常
移到句子后部,而用it作形式宾语。
例句:I find it necessary that we
should do the homework
on time.
(二)由whether,if 引导的宾语从句
由w
hether(if)引导的宾语从句,实际上是一般疑问句演变而
来的。意思是“是否”。宾语从句要
用陈述句语序。一般说来,在宾
语从句中whether与if可以互换使用,但在特殊情况下if与w
hether
是不能互换的。
例句:I wonder
whether(if) they will e to our party.
只能用whether,不能用if引导的宾语从句
在带to的不定式前
例句:We decided whether
to walk there.
在介词的后面
例句:I’m thinking of whether we should go
to see the film.
在动词后面的宾语从句时
例句:We discussed whether we had a
sports meeting next
week
直接与or not连用时
例句:I can’t say
whether or not thet can e on time.
只能用if不能用whether引导的宾语从句
if引导条件状语从句,意为“如果”
例句:The
students will go on a piic if it is sunny.
if引导否定概念的宾语从句时
例句:He
asked if I didn’t e to school yesterday.
引导状语从句even if(即使)和as if(好象)时
例句:He talks as if he has known all about
it.
(三)连接代词和连接副词引导的宾语从句
这样的宾语从句实际上是由特殊疑问句变化而来的,宾语从句
要用陈述句语序。用于
这种结构的动词常常是:see, say, tell, ask,
answer,
know, decide, show, find out, imagine, suggest,
doubt,
wonder, discover, understand, inform,
advise等。
英语中的连接代词有:who,whom,whos
e,which,what,在句中担
任主语、宾语、定语或者表语。
例句:Can you tell me whom you are waiting for?
英语中的连接副词有:when,where,why,how,在句中担任状语
的成分。
例句:None of us knows where these new parts
can be bought.
宾语从句的语序是陈述句语序即:连接代词副词+主语+谓语+
其他成分。例句如下:
I don’t know what they are looking for.
Could you tell me when the train
will leave?
Can you imagine what
kind of man he is?
主句是一般现在时,从句根据实际情况使用任何时态。
例句:The
headmaster hopes everything goes well.
主句是过去时态,从句须用过去时态的某种形式。
例句:She was sorry that she hadn’t finished her work
on
time.
当宾语从句表示的是一个客观真理或者事实时,即使主句是过
去时,从句也用一般现在时态。
例句:The teacher told his class
that light travels faster
than sound.
宾语从句可以作及物动词、介词及形容词的宾语。
宾语从句的语序一律用陈述句语序。
连接词that引导宾语从句在句中无词义,不充当句子成份,多
数情况下可以省略。
whether 和 if 都可引导宾语从句,但
whether后可紧跟or
not;whether从句可作介词的宾语。
如果从句太长,可以用形式宾语it.
