宾语从句的用法_who引导的宾语从句用法 _生活经验

宾语从句的引导词的用法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。
that引导的宾语从句
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, command, 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 planets.
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?。竺娴膖hat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.
由whether,if 引导的宾语从句
由whether(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whether是不能互换的。
例句：I wonder whether(if) they will come 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 theycan come on time. 只能用if不能用whether引导的宾语从句
if引导否定概念的宾语从句时例句：He asked if I didn’t come to school yesterday.
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,whose,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.

if引导的宾语从句的用法whether和if都可以引导宾语从句，表示“是否”，在口语或间接引语中两者可以互换使用。如：
I wonder if / whether I can get some advice from you.
Ask him whether / if he can come.
但在有些情况下，whether和if的用法有一定区别。
1. whether引导的从句常可以与连词or或or not直接连用，而if一般不能。如：
正： Let me know whether you can come or not.
误： Let me know if you can come or not.
2. 当宾语从句提到句首时，只能用whether引导，而不能用if 。如：
正： Whether it is true or not, I can’t tell.
误： If it is true or not, I can’t tell.
3. whether可以引导带to的不定式，if则不能。如：
正： I don’t know whether to accept or refuse.
误： I don’t know if to accept or refuse.
4. whether及其引导的成分可放于介词之后，作介词的宾语，但if不能。如：
正： I worry about whether I hurt her feelings.
误： I worry about if I hurt her feelings.
5. whether可以引导从句，作主语、表语或同位语，而if不能。如：
正： It was uncertain whether he would come.
误： It was uncertain if he would come.
正： His first question was whether Tom had arrived yet.
误： His first question was if Tom had arrived yet.
宾语从句的时态用法？宾语从句的时态问题
1）当主句的谓语动词是一般现在时时，其宾语从句的时态可以是任何适当的时态。所以，宾语从句的时态应根据实际情况而定。eg.
She says (that) she works from Monday to Friday.她说她从周一至周五上班。
（从句是一般现在时）
She says (that) she will leave a message on his desk.她说她要在他桌子上留个便条。
（从句是一般将来时）
She says (that) she has never been to Mount Emei.她说她从来没有去过峨嵋山。
（从句是现在完成时）
2）当主句的谓语动词的时态是一般过去时的时候，其宾语从句的时态一般要用任一适当的过去时态。eg.
He said there were no classes yesterday afternoon. 他说昨天下午没有课。
从句是一般过去时）
He said (that) he was going to take care of the baby.他说他会去照看这个婴儿。
（从句是过去将来时）
He said (that) they were having a meeting at that time.他说他们那时正在开会。
（从句是过去进行时）
但是当宾语从句是表达客观真理和规律的句子时，其时态仍旧用一般现在时。eg.
The teacher told us(that) nothing is difficult ifwe put our hearts into it.
老师告诉我们世上无难事,只怕有心人。
She said(that) her father is twenty-eight years older than her.
她说她父亲比她大二十八岁。
He said that light travels much faster thansound.
他说光比声音传播得快。
He told me that I must go to school on timeevery day.
他告诉我我必须每天按时上学。
注意：当主句的谓语动词是think或believe ，宾语从句要表达否定时，要把从句的否定转移到主句上。eg.
我认为他不会帮你学英语的。
I don't think he is going to help you with your English.
不可以翻译成：
I think he isn't going to help you with your English.
如果宾语从句有它的补语时，宾语从句用it代替，从句后置。其句型为：主语+谓语 + it +补语+宾语从句。eg.
I think it necessary that we learn Englishgrammar.
我认为我们学习英语语法是必要的。
He thinks it a good job that he becomes ateacher.
他认为当老师是个很好的职业。

宾语从句中which的用法which 其实很少用，一般用what，但which却是有意义的，它表示有选择的事物，而what可以说没什么实际意思。打个比方：There are two shirts right there,I'll buy which is cheaper.这里要用which因为是有一个范围，即two shirts 。而一般的宾语从句中一般用what 。
英语中宾语从句that的用法？宾语从句中that　口语中可省略，没有意义，如
He said( that ) he was not here just now .
加油！不明白再问！如果帮到你，请，谢谢！
【宾语从句的用法_who引导的宾语从句用法】扩展
不是说that是引导陈述句的吗？但是但是宾语从句的从句都是陈述语序。那该怎么判断？还有其它方法判断吗？

补充
应该说是由陈述句变宾语从句时引导词用that ，口语中可省略。
如 " I am a teacher ' , he says ->He says (that ) he is a teacher .

if引导的宾语从句的用法是什么？1、主将从现：
If it rains(从句) ,I will stay at home（主句）.
=I will stay at home if it rains.
2、一般现在时：
If you drive too fast ,you may have an accident.
=You may have an accident if you drive too fast
3、主句为祈使句,从句要用一般现在时态：
Don't play computer games if you don't finish your homework.

I wonder if / whether I can get some advice from you.

1. whether引导的从句常可以与连词or或or not直接连用，而if一般不能。如：

4. whether及其引导的成分可放于介词之后，作介词的宾语，但if不能。如：
正： I worry about whether I hurt her feelings.
误： I worry about if I hurt her feelings.
5. whether可以引导从句，作主语、表语或同位语，而if不能。如：
正： It was uncertain whether he would come.
误： It was uncertain if he would come.
正： His first question was whether Tom had arrived yet.
误： His first question was if Tom had arrived yet.
who引导的宾语从句用法这个问题很好。who在引导宾语从句时可以在从句中做主语，也可以代替whom做宾语表语。因此会出现两种情况。当作主语时是who is当做宾语表语时是who he is.
I don't know who is his dad.
I don't know who he is.
I don't know who loves him.
I don't know whom(who) he loves.
