)(2) 从属连词if/whether。

如:I doubt whether he will succeed. 我怀疑他是否会成功。

if和whether引导的宾语从句可以互换使用,但whether常和or not连用,if一般不与or not连用。

如:I wonder whether it is true or not. 我不知它是真是假。

用if引导宾语从句如果会引起歧义,应避免使用if而用whether。

动词如:advise, ask, inform, promise, question, remind, show, teach, tell, warn等,宾语从句前可以有一个间接宾语,这个宾语有时可以省略,有的不能省略。

He has informed me when they are to discuss my proposal.他已经通知我们将什么时候讨论我的建议。

(me不可省略)(3)形容词或过去分词后接宾语从句I am not certain whether I have met him before.我不能肯定从前是否见过他。

名词性从句精简讲义

名词性从句精简讲义

名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。

(一)引导名词性从句的连接词1、连接代词:who, whose, whom, what, which。

有词义,在从句中担任成分,如主语、表语、宾语、或定语等。

2、连接副词:when, where, why, how。

有词义,在从句中担任成分,作状语。

3、连接词:that, whether,if, as if无词义,在从句中不担任成分,有时可省略;if (whether), as if虽有词义,但在从句中不担任成分。

(二)主语从句1、主语从句在复合句作主语,通常由从属连词that,whether(只起连接作用) 和连接代词what, who, which, whatever, whoever以及连接副词when,where, why,how,等词引导。

e.g. Who will go is not important. What he said made his mother very angry.2、用it作形式主语,主语从句放在句末。

这样就构成了下面一些常用句型:1) It is + n. +从句It is a pity/shame/ surprise/ fact/common knowledg that...2) It is + adj. +从句It’s certain/ possible/ unlikely / obvious/ that…It’s necessary \important \natural\ that…+(should) +do…3) It +不及物动词+从句It occurred/seems to me /happened that...4) It + be +过去分词+从句It is said / known to all / reported / believed /that...It is suggested that + (should)do... 建议……It must be admitted that…必须承认……It cannot be denied that…不可否认…… It must be pointed out that…需指出的是……*It is reported that (据报道)20 people were killed in the accident.3、that虽然在从句中无词义,只起连接作用,但是一般不省略。

3. 连接副词:when(=the time when什么时候,何时),where(=the place where什么地方,何地),how(=the way that/in which怎样, 以……方式,如何),why=the reason why为什么)。它们除起连 接作用,还在从句中作状语。
3) wh类连接词引导的主语从句: wh类连接词包括wh类的连接代词(who, whom,
whose, which, what, whoever, whomever, whichever, whatever等)和连接副词(when,
where, how, why, whenever, wherever, however 等)。what, when和wh-ever类的词有时可不表 疑问。wh类连接代词在句中既起连接作用, 又可充当主语、宾语、表语、定语等成分。 wh类连接副词在句中起连接作用,在从句中 可充当时间、地点、原因、方式状语。
【温馨提示】 ①whether/ if引导宾语从句表示“是否”
的意思时,一般情况下可互换。 ②if引导宾语从句时可以有否定式,而
whether从句则没有。 e.g. I don’t care if he doesn’t come.
5) 特殊疑问词引导的宾语从句: 由who, what, how, which, whose, where, why等词引导的宾语从句,可作动词、 介词及形容词的宾语。
【温馨提示】 doubt, doubtful与sure后名词性从句连接词 that, whether, if的选择。 ①当doubt, doubtful用于肯定句时,后面的名
词性从句的连接词常用whether或if;当 doubt, doubtful用于否定句或疑问句时,后 面名词性从句的连接词用that。
