问英语的宾语从句是什么意思?给几个例子?如何记住那?
宾语从句就是一个句子在复合句中作动词或介词的宾语,在主句与从句之间有一个引导词,其结构为“主语+谓语动词+引导词+主语+谓语+其 它”.
主句 宾语从句
焦点一：宾语从句的引导词
1.宾语从句具有陈述意义时用that引导.that无具体意思,不作任何成分,因此在口语或非正式文体中常常被省略.如：
She said (that) she would leave the book on his desk.她说她会把那本书放在他的桌子上.
● 从句的主语是that时,that不能省略；主从句之间有插入语时,that不能省略；若出现两个或两个以上的that宾语从句,且由并列连词连 接时,只有第一个连词that可以省去,其余保留.如：
It says here,on this card,that it was used in plays.卡片上写着,它过去是演戏用的.
He thought that that was a washing machine.他认为那是一台洗衣机.
My aunt said (that) she would come and that she would also bring her daughter.我姑姑说她要来,还要带她的女儿来.
2.当宾语从句由一般疑问句变化而来时,用if或whether来引导从句,意为“是否”.如：
Alice wanted to know if / whether her grandmother liked the bag.艾丽斯想知道她祖母是否喜欢这个包.
在下列几种情况下,只能用whether,不能用if:
● 当or not 紧随连词之后时.如：
I don't know whether or not he will come on time.我不知道他能否按时来.
● 从句用作介词宾语时.如：
I am interested in whether he joined the army.我对他是否入伍很感兴趣.
● 在带to的动词不定式前.如：
She doesn't know whether to go to the cinema or to watch TV at home.她不知道是去看电影还是在家看电视.
● 当宾语从句移至句首表强调时.如：
Whether this is true or not,I'm not sure.这是否真实,我不敢肯定.
3.宾语从句具有特殊疑问含义时用连接代（副）词引导,它们在宾语从句中充当一定成分,因此不能省略.如：
Did you hear what he said?你听见他说的话了吗?（作宾语）
I don't know whose that is.我不知道那是谁的.（作表语）
Could you tell me how I get to the post office?你能告诉我到邮局怎么走吗?（作状语）
焦点二：宾语从句的语序
无论宾语从句的主句是陈述句还是疑问句,也无论主从句间是什么引导词,宾语从句一律用陈述语序,即“引导词+主语+谓语+其它”.如：
Could you tell me?/ Where does Wei Fang live?
→Could you tell me where Wei Fang lives?
● 当疑问代词who,what等在从句中作主语时,语序本来就是陈述语序,故语序不再变化.如：
Who will give us a talk?Please tell us.
→Please tell us who will give us a talk.
焦点三：宾语从句的时态
● 如果主句是祈使句或主句中的谓语动词是一般现在时或将来时,则宾语从句可根据句意的需要而选用任何一种时态；若主句是一般过去时 ,宾语从句用表示过去的某种时态.
He says that he wants to see him as soon as possible.他说他想尽快见到他.
My father said that he was mending his bike.我父亲说他正在修理自行车.
● 如果宾语从句表示客观真理、科学原理、自然现象、现阶段存在的客观事实、现在经常性或习惯性的动作、谚语、格言等,不论主句用何 种时态,从句一律用一般现在时.如：
The teacher told us that light travels much faster than sound.老师告诉我们光比声音传播快.
