什么是宾语从句?我还小,不理解.【这素刚学新概念的英语的小妹纸..

1,什么是宾语?
I know him.
Do you have the time?
I think (that) she is beautiful.
Why don’t you pay attention to me?
宾语
位于谓语动词或者介词后
2,宾语从句的概念
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）或介词之后.
e.g.We know Mr.Green teaches English.
She asked if these answers were right.
3,宾语从句三要素
引导词（连接词）
语 序
时态
（一）引导词
[1]由从属连词 that 引导的宾语从句
注：that 在句中无词汇意义,在从句中不能充当成分,在口语当中往往省略
e.g.
I hear (that) he will be back in an hour.
that——不能省略的2种情况:
1）当that作介词except,in 宾语时
They believe in that she must still be single.
I know nothing about him except that he is living in Beijing.
2）用it做形式宾语的宾语从句时
（ it常可以放在动词think,find,consider,believe,feel,make等后作为形式宾语,而真正的宾语——that从句则放在句尾）
I think it necessary that you should read English aloud.
We heard it that she would get married next month.x0b
[2]由从属连词 whether,if 引导的宾语从句
if/ whether “是否”,说明对陈述的事物不明确或不清楚.常用在ask,wonder,can(could) you tell me 等后.
I want to knowif (whether) he will go to the park with us .
只能用 whether不能用 if 的情况
1.在介词后面：
I’m thinking of whether we should go fishing.
We are worried about whether it will rain tomorrow.
2.在动词不定式前(whether to do sth.) ：
They asked me whether to go skating.
3.当与or not连用,或提出两种选择时:
I don’t know whether he’s free or not.
Mary asked whether I was doing my homework or not.
Tell me whether you’d like to go shopping or tidy the room.
4.宾语从句提前时：
Whether this is true or not,I can’t say.
[3]由连接代词 who,whom,whose,which,what和连接副词 where,how,why,when引导的宾语从句.
代词或副词连接主句和从句,并在从句中担任句子成分,具有一定的意义,不可省略.
He asked who could answer the question.
(二)语序
宾语从句的语序用陈述语序：连接词+主语+谓语+其他成分
1.When will he go to the library?
His brother asks when he will go to the library .
His brother asks when will he go to the library .
2.What did he want to buy
I don’t know what did he want to buy .
I don’t know what he wanted to buy .
注：当从句的原句为以下句子以及what,who作主语时,语序不变：
What’s wrong?What’s the matter?
What’s happening?What happened?
eg:
I don’t know what’s the matter..
Can you tell me who is over there?
Can you tell me who he is
否定的转移：若主句谓语动词为think,consider,suppose,believe,expect,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.
I don’t think this dress fits you well.
I don’t think you are right.
（三）、时态
1,主句用现在时或将来时,从句可用任何时态,根据实际情况而定.
I know he lives here .
I know he lived here ten years ago .
I have heard that he will come tomorrow .
2.如果主句是过去的时态（一般过去时,过去进行时）,从句的时态一定要用相对应的过去的某种时态（一般过去时,过去进行时,过去将来时,过去完成时）
I knew who lived here.
I saw she was talking with her mother.
He asked whether his father would come back tomorrow.
He said that he had seen it .
3.从句说明的是一般真理、客观事实、自然现象时,仍用一般现在时.
Dad told us that it is better to do than to say.
He told the boy that three and three is six.
He told me the earth moves around the sun.
4.从句中有具体时间状语,即使从句动作发生 在主句动作前,仍用一般过去时.
The teacher told me she was born in 1960.
I heard that he went to Paris last night.

好
咱就用一个简单的说法来解答你的问题。
宾语，你应该知道，就是句子中 动作施加的对象。比如。i play football. football 就是宾语。
但是当有时候宾语的内容比较多，用一个两个单词不够时，就会用一个句子来充当，这时候，宾语从句就出现了。宾语从句
例如 i believe that he is honest. 我相信他是诚实的。这种情况下...

充当宾语的是一个句子就是宾语从句了
