新东方名师教你20分钟搞定英语名词从句

　　四、一般疑问句可分别充当四种句子成分。1、一般疑问句语序变成陈述语序。2、用来whether或if引导。

　　1.主语从句: does she love dog-walking?

　　Whether she loves dog-walking or not is unknown.

　　2.宾语从句:

　　I don’t know if/whether whether she loves dog-walking

　　3.表语从句:

　　My concern is whether you are a student or not.

　　4.同位语从句:

　　They are faced with the problems whether they should continue to play.

　　补充：if whether区别

　　1)if一般用于引导宾语从句，而whether可引导所有名词从句

　　If he comes or not makes no difference.

　　The question is if he will arrive.

　　2)if 不和or not直接连用，一般不说 if or not。但可以说 if … or not 。而whether没有此限制。

　　I don’t know if or not he arrives.

　　I don’t know whether or not he arrives.

　　五、特殊疑问句可分别充当四种句子成分。特殊疑问句变成陈述句语序。

　　There arose the question where we could get the loan.

　　I have no idea what gender he is.

　　Why he refused to cooperate with us is still a mystery.

　　I don’t know how many letters I have written to her.

　　NBA is what I am crazy about.

　　How China should develop next is a serious problem.

　　Excuse me, can you tell me where the post office is?

　　My question is where we are going to have our holidays.

　　The point is whose book is the most horrible.

　　Whoever comes will be welcomed.

　　Whatever is left over is yours

　　Do whatever you please.

　　Read whichever books you please.

　　I'll give it to whichever of you wants it.

　　P.S. 最后说明：同位语从句多用that引导，少用whether, if以及代词或副词引导，因为我们多是用陈述句补充名词的内容，而少用一般疑问句或特殊疑问句来补充名词的内容。

　　温故知新：名词从句就是用三种句子来分别充当另外一个句子的四种句子成分。
