九年级英语语法丨宾语从句精讲精练！
宾语从句的用法(一)
宾语从句是指在复合句中充当宾语的句子,九年级学生主要学习的是由that ,if, whether引导的宾语从句。
1.当宾语从句由陈述句变化而来时,由that来引导从句,其中的that无具体意义,在口语中可以省略。如:
I believe that I can get good results in this math test.我相信在这次数学测试中我能取得好成绩。
I believe that our team will win the basketball match.我相信我们队会在这场篮球比赛中获胜。
The teacher said that Li Lan is a working-hard child .老师说李兰是一个努力学习的孩子。
Academician Zhong Nanshan said that we should take the new epidemic situation seriously.钟南山院士说我们应该认真对待新的疫情。
Academician Li Lanjuan said that after the end of the epidemic, the national should set up a correct life orientation and a correct outlook on life for young people. 李兰娟院士表示，疫情结束后，国家应该为青少年树立正确的生活取向和人生观。
2.当宾语从句由一般疑问句变化而来时，可用if或whether来引导,意为“是否”。从句部分用陈述语序。如:
My mother asked me if I went to the library yesterday?妈妈问我昨天是否去图书馆了。
The teacher asked him if/whether he understood the problem?老师问他是否理解这道题了。
3.宾语从句的时态:如果主句是一般现在时,宾语从句的时态可根据具体情况而定;如果主句是一般过去时,宾语从句也常用相应的过去时态。如:
I know (that) LiLei is a hard-working student.我知道李雷是一个努 力学习的学生。
I know (that) he will go to Beijing tomorrow.我知道他明天将去北京。
He said his mother would visit his grandmother .他说他妈妈将去看望他外婆。
4.如果宾语从句表示客观事实或真理时,其时态不受主句限制,一律用一般现在时。
①The geography teacher told us that the sun rises in the east.地理老师告诉我们太阳从东方升起。
②The physics teacher told us that the speed of light is faster than that of sound.
物理老师告诉我们光速比音速快。
③Mother said the earth goes around the sun.妈妈说地球绕着太阳转。

宾语从句的用法 [二]
一、特殊疑问句的宾语从句
当宾语从句是由连接代词who, whom, whose ，what,which或连接副词where, when, how , why等引导的特殊疑问句时,这时特殊疑问词就是宾语从句的引导词,从句部分要用陈述语序。如:
I want to know how to use this computer. 我想知道如何使用这台电脑。
l don't know what he is. 我不知道他是做什么工作的。
She didn't know where she would go.她不知道她要去哪里。
No one knows where he comes from.没有人知道他来自哪里。
二、宾语从句与简单句的转换
在宾语从句中,当宾语从句是特殊疑问句时,我们可以把特殊疑问句充当的宾语从句转换成复合不定式短语,在句中作及物动词的宾语。如:
①Will you please tell me how I can get these information?
=Will you please tell me how to get these information?请你告诉我怎样获得这些信息好吗?
②Can you tell me when we will arrive in Beijing?
=Can you tell me when to arrive in Beijing？
你能告诉我我们将在什么时候到达北京吗?
三、只用whether不用if的情况
①引导介词后的宾语从句时。
l am interested in whether he joins the army.我对他是否人伍感兴趣。
②直接与or not连用时。
I can't say whether or not he will come on time.他能否准时来，我说不准。
I'm not sure whether or not Mary is coming to my birthday party. 我不确定玛丽是否会来参加我的生日聚会。
③引导动词discuss后的宾语从句时。
They're discussing whether we should visit the Summer Palace tomorrow . 他们正在讨论我们明天是否去参观颐和园。
④宾语从句前置于句首时。
Whether this is true or not, I'm not sure.
这是不是真的，我不敢肯定。
Whether he is going to Australia? I don't know. 他是否要去澳大利亚?我不知道。
【注意】
①在用if会引起歧义时也只能用whether。
Please tell me if he can come to my birthday party.
这句话可以理解为:“如果他能来参加我的生日聚会，请告诉我。”或“请告诉我他能否来参加我的生日聚会。”如果表达第二种意思，只能用whether。
②与动词不定式连用时也只能用whether。
Tomorrow mother will tell us whether to travel to Beijing.明天妈妈将告诉我们是否去北京旅游。
四、宾语从句应注意的事项
1. 宾语从句一定要用陈述语序。
My mother asked me when we would have an English test.我妈妈问我什么时候会有一个英语测试。
2.宾语从句的否定前移
当主句是般现在时， 主语是第一人称w.Ei主句谓语动词是表示“想，，认为'等意义的动词，如think, believe, suppose等时，若后面的从句是否定意义。从句的否定般要转移到主句中，即: 否定前移。其反意疑问句的人称和时态通常与宾语从句一致。
①I don't think LiMing is an honest child ， is he?我认为李明不是个诚实的孩子，是吗?
②I don't think he can play the piano，can he?我认为他不会弹钢琴，对吗？
③I don't believe he is clever, is he?
我认为他不聪明，是吗?
3.宾语从句不能省略that的情况
在that 引导的宾语从句中，连接词that只起引导作用，无具体意义，在从句中不充当任何成分，因此在口语或者非正式文体中常常省略。但在下列情况中不能省略：
(1)句中出现两个或两个以上由that引导的宾语从句时。
由并列连词连接的两个或多个that引导的宾语从句，只有第一个从句中的 that可以省去，其余并列宾语从句中that全要保留。
Tom said ( that ) he had finished reading the book and that he would read another one.汤姆说他已读完了这本书,想再读一本。
【拓展】当宾语从句的主语是非谓语动词或从句中时，that不能省略。
Most people couldn't believe that what he had written was true.大多数人不相信他所写的是真的。
( 2 )that从句中又有其他从句时。
I want to know that if you are going to Beijing。我想知道你是否去北京。
I am afraid that if you've broken it, you must pay for it.你如果损坏了它，恐怕必须赔偿。
(3)it作形式宾语代替that引导的宾语从句时。
They took it for important that we would help them.他们认为我们帮助他们很重要。
(4 )当宾语从句的主语是this, that或者被this,that修饰时。

她说这本书非常有用。

他告诉我们那就是他迟到的原因。
(5)当宾语从句是双宾语中的直接宾语时。

(6)当宾语从句前有插入语时。
We told him once again that this would neverhappen.我们再次告诉他，这种事情绝不会发生。
4.宾语从句的简化
(1 )当宾语从句的主语和主句的主语相同，且主句的谓语动词是hope, wish, decide, agree, choose等时，从句可简化为动词不定式结构。
I hope that I can visit the Great Wall.
=I hope to visit the Great Wall.
我希望能观长城。
(2)当宾语从句的主语和主句的主语相同，且主句的谓语动词是know，remember, forget, learn 等时，从句可简化为“疑问词+动词不定式”结构。
I didn't know how I could deal with it .
=I didn't know how to deal with it .
我不知道怎么处理这件事。
(3 )当主句的谓语动词是see, watch, hear等感官动词时，从句可简化为“宾语+宾语补足语”结构，宾语补足语为不带to的动词不定式或者动词-ing形式。
Amy saw the wallet was lying on the floor.
=Amy saw the wallet lying on the floor.
爱米看见钱包躺在地板上。
(4)宾语从句有时也可简化为名词或名词短语。
We don't believe what the girl said.
=We don't believe the girl's words
我们不相信那个女孩所说的话。
【温馨提示】
宾语从句还可以简化为“it+形容词+动词不定式短语”的形式。

I find it easy to work out the problem.我发现解出这 道题很容易。
