在从句
中充当从句的成分?不可省略的连词：?1. 介词后的连词?2.
引导主
语从句和同位语从句的连词不可省略。
或介词之后。 did not
know what had
happened.(作动词
的宾语)宾语从句就是在复合句中作宾语的名词性从句，
通常放在主
句谓语动词 (及物动词) 2. Our suess depends upon
how well we can
cooperate with one another.3.
I am afraid (that) I’ve made a
mistake.
宾语从句(作介词的宾语)(作形容词的宾语)? 1.
由连接
词that引导的宾语从句由连接词that引导宾语从句时，
that在句
中不担任任何成分， 在口语或非正式的文体中常被省去，
但如从句
是并列句时,第二个分句前的that不可省。 例如：?? We must never
think (that) we are good in everything while
others are good
in nothing. ? 注意： 在demand，
order，suggest， decide， insist,
desire,
request, mand, doubt等表示要求、 命令、 建议、 决定
等意义的动词后，
宾语从句常用“（should） + 动词原形”。
? I insist that
she (should) do her work alone. 我坚持要
她自己工作。?
The mander ordered that troops (should) set off
at once. 司令员命令部队马上出发。?2.
用whether或if引导的宾
语从句， 其主语和谓语的顺序也不能颠倒， 仍保持陈述句语序。
此
外，whether与if
在作“是否”的意思讲时在下列情况下一般只能
用whether， 不用if：?a.
引导主语从句并在句首时； b. 引导表
语从句时； c . 引导从句作介词宾语时； d.
从句后有“or not”
时； e. 后接动词不定式时。? Whether there is
life on the moon
is an interesting question. ?
The question is whether she should
have a low
opinion of the test? ? Everything depends on
whether
we have enough money. ? I wonder
whether he will e or not. ?
Can you tell me
whether to go or to stay?
宾语从句中的“时态
呼应”与“否定转移”若主句谓语动词为think, consider,
suppose,
believe,expect, fancy, guess,
imagine等， 其后的宾语从句若
含有否定意义，
一般要把否定词转移到主句谓语上， 从句谓语用肯
定式。
例如：我认为他不会来这里.I think he won’t e here.()I don’
t
think he will e here.()He told me that he
____________ his
job. (已经完成了工作)时态呼应否定转移had
finished?4. 注意宾
语从句中的时态呼应， 当主句动词是现在时，
从句根据自身的句子
情况， 而使用不同时态。 例如：I know (that) he
studies English
every day. I know (that) he
studied English last term. I know
(that) he
will study English next year. I know (that) he has
studied English since 1998. 当主句动词是过去时态（could,
would
除外） ， 从句则要用相应的过去时态， 如一般过去时， 过去进行
时，
过去将来时等； 当从句表示的是客观真理， 科学原理， 自然
现象， 则从句仍用现在时态。
? The reason why he was late was that he
missed the train
by one minute this morning .
【注意】 whether 可引导表语从句，
但与之同义的if却通常不用于引导表语从句。在句中起同位语的作
用.
一般放在名词fact , news , idea , promise, thought ,
suggestion, belief, truth 等之后, 用以说明或解释前面的名词.
引导词有连词 that(不能省) ； 少数情况下也可用连接副词等.省) ；
少数情况下也可用连接副词等. thought that we might sueed

般放在名词fact , news , idea
, promise, thought , suggestion,
belief, truth
等之后, 用以说明或解释前面的名词. 引导词有连

同位语从句和定语从句的区别：? that

宾语时可以省略；that引导同位语从句时， 起连词的作用， 没有
实际意义，
