that引导的宾语从句

that引导的宾语从句

that引导的宾语从句宾语从句是一种名词性从句,在句中作及物动词的宾语,或介词的宾语,或形容词的宾语。

根据引导宾语从句的不同连词,宾语从句可分为三类。

(1)that引导的宾语从句(2)whether / if引导的宾语从句(3)疑问词引导的宾语从句一、由that引导的宾语从句:that只有语法作用,没有实在的意义,在口语和非正式文体中可以省略。

例如:He said (that) he wanted to stay at home.他说他想呆在家里。

She doesn’t know (th at) she is seriously ill.她不知道她病得很严重。

I am sure (that) he will succeed.我确信他会成功。

小试牛刀:1、She said. You looked great!2、She said. I went to Beijing and visited the Great Wall.注意:(一)并非所有的动词后面都可以接that引导的宾语从句,只有当谓语动词表示肯定概念时,如believe, expect,explain, feel, hear, hope, imagine, prefer,promise, report, say, see, tell, think,understand, warn, wish等其后面的句子一般由that引导。

此时,that没有任何实际意义,目的是使读者清楚后面的句子是作前面动词的宾语,多数情况下可以省略。

(二)不能省略that的2种情况:1、当that作介词except, in 宾语时例如: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)例如:We heard it that she would get married next month.课堂练习:( )1、Don’t lose your heart. I believe in you can finish the work by yourself.A. \B. thatC. whichD. if( )2、I think we can be good friends.A. thatB. whatC. whichD. if( )3、She said he would go to the hospital.A. \B. whatC. whichD. if( )4、-Have you ever seen the movie 2012?-Yes, but I don’t believe ____ the year 2012 will see the end of the world. 【2012 菏泽】A. thatB. whatC. howD. if二、特殊的宾语从句———间接引语用自己话转述别人的话,叫做间接引语。

八年级从属连词that及ifwhether和疑问词引导的宾语从句详细

八年级从属连词that及ifwhether和疑问词引导的宾语从句详细
在疑问词引导的宾语从句中,一定要用陈 述语序。
引导词:取决于从句的语气
1.从句是陈述语气时,引导词用that. 2.从句是一般疑问语气时,引导词用if或 whether. 3.从句是特殊疑问语气时,引导词用特殊疑问词。 e.g: I'm afraid that you are right.
I want to know if it will rain tomorrow. I didn't hear what he wanted me to do . Do you know whose bag I am carrying? He asked me if I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.
1.I hear (that) he will be back in an hour .
(一小时后他会回来)
1.He said (that) he missed us very much.
这些例子中的宾语都是用一个单词或者短语来表 达的。
• 但是,如果你想要表达“我知道你昨天 看电影了”时,我们就无法在know后用 一个简单的单词表达“你昨天看电影了” 这个结构中的本身完整的一个句子,此 时我们就只能用句子表达。
那这种发在动词后面做宾语的句子,即 “宾语从句”。
定语从句
念:句子的宾语一般由名词、代词、动名词或动词不定式充当,当一 个句子充 宾语时,我们把这个句子叫做宾语从句。 一般句子的主要成分都是主语谓语宾语,从句的意思是句子里面还有句子,宾 从句就是说由一段句子作宾语的句子)
(他非常想念我们)
1.The teacher told us (that) the earth moves around the sun. (地球围着太阳转)

从学生角度分析为什么难
英语句型的转换和单独的时态问题就是学生学习的难点,而疑问句在宾语从句中的语序变化,以及在从句中要根据主句的时态变化而变化,就更让学生感到迷惑,难以掌握。
难点教学方法
1.通过视频,动画等情境教学,感悟宾语从句的语序、引导词、时态三要素的重点知识。
2.通过讨论及问题探究,能正确使用that, if/whether ,特殊疑问词引导的宾语从句。
(2)投篮游戏(一筐一球)活动,来编排宾语从句的语序。通过形象思维,激发学生的兴趣,
Step4.引导词
1.that引导的宾语从句
展示图片和句子Ibelieve(that)I can fly.引导学生分析宾语从句的特征:
★陈述句前用that引导
★that在句中无意义,可省略。
★从句部分为陈述语序。
2.if或whether引导的宾语从句
Step 3.宾语从句的语序 我是小神探
(1)鼓励学生当小神探,快速找到句子的宾语从句部分。探究主句、从句部分的语序。
He wonders if you hurt the girl.
He askswhatyou are doing
He wondershowhe can grow up
得出结论:主+谓+其它陈述语序

主句为一般过去时:从句用相应的过去的某一种时态

宾语从句

宾语从句

宾语从句一、定义:当一个句子充当宾语时,我们就把这个句子叫宾语从句,含有从句的句子叫主句,主句和从句之间有连接代词或连接副词。

二、宾语从句的三类引导词1.由that引导的宾语从句陈述句作宾语,由that引导,that 在句中没有词义,也不做任何句子成分,并且在口语中常常省略。

如:I think (that) he is very old.He says (that ) he will come back tomorrow.He said (that) he wanted to see the teacher.2.由if或whether引导的宾语从句由if/whether连接一般疑问句句式,要特别注意把语序改为陈述句语序。

if/whether在句中具有词义“是否”,不能省略。

在口语中常用if,wether常与or not连用。

如:He asked if/wether they needed more tea.I don’t know wether he will pass the exam or not.注意:当主句动词跟宾语从句时,要把谓语动词say改为tell或ask。

如:Can tom do the work? Miss Gao said to Tim.==>Miss Gao asked Tim if/whether Tom could do the work.3.疑问词引导的宾语从句当宾语从句时特殊疑问句时,由疑问词来引导,用陈述句语序,即:“主句+疑问词+主语+谓语+…,”疑问词不能省略。

如:Do you know what he has done?Please ask which book is hers.Can you tell me when the plane wii take off?三、宾语从句“一、二、三”1.“一”,指一种语序,从句必须用陈述句语序。

如:Is Mr Wu a teacher? Please tell me.-->Please tell me if/whether Mr Wu is a teacher.What can he do? I say to them.-->I ask them what he can de.2.“二”,指两种时态,即从句的时态要根据主句的时态来确定时态。

I am glad that you can join us.种类:根据不同的引导词分为三类:that引导:He said that he wanted to stay at home.whether/if引导:He asked me whether/if(是否) he could go.特殊疑问词引导:Can you tell me where the No.3 bus stop is?二、宾语从句——引导词、语序、时态1. 引导词①由_______________引导I don’t know (that) she is seriously ill.I am sure (that) he will succeed.that后加陈述语序,由陈述句变化而来。

这里的that只有语法作用,没有实在的意义,在口语和非正式文体中常省略。

②由_______________引导(其意思是__________)I want to know whether/if she likes Zhengzhou.He asked me whether/if I could help him.whether/if后加陈述语序,由一般疑问句转化而来。

宾语从句讲解

宾语从句讲解

宾语从句宾语从句是的一种。

在中充当,位于、或之后的从句称为。

宾语从句分为三类:的宾语从句,的宾语从句和的宾语从句。

用法宾语从句结构:++由连词引导宾语从句(陈述语序)连接宾语从句的从属连词主要有that,if,whether,和疑问词(what,how,where,when ...)。

1)that (无词义,不做成分); if,whether(表达是否的意思,但是不做句子的成分)that引导表示的宾语从句,if和whether,whether...or not引导表示“是否”的的宾语从句。

If和whether的区别:if和whether在作“是否”理解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,后一般不用if。

少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether。

whether后可以加or not,但是if不可以。

在前只能用whether。

一般“no matter”示“是否”用whether而不用if。

2)主要有:who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。

连接代词一般指疑问,但what,whatever除了指疑问外,也可以指陈述。

Tell him which class you are in .Do you know what he likes?3)主要有when,where,why,how,whenever,wherever,however等。

He didn’t tell me when we should meet again. 他没有告诉我什么时候我们能再见面。

注:宾语从句通常跟在名词或代词后面。

宾语从句--动宾从句大多数都可以带宾语从句。

部分“+”结构也可以带宾语从句。

动词短语也可以带宾语从句,常见的这些词有:make sure(确保)、make up one’s mind(下决心)、keep in mind(牢记)可运用it代替的宾语从句①动词find,feel,consider,make,believe,think等后面有宾语补足语的时候,则需要用it做形式宾语而将that宾语从句后置。

宾语从句正确引导和使用直接和间接宾语从句

宾语从句正确引导和使用直接和间接宾语从句

宾语从句正确引导和使用直接和间接宾语从句在英语中,宾语从句是指作为宾语的句子。

宾语从句可以分为直接宾语从句和间接宾语从句。

直接宾语从句是指宾语从句直接引导整个句子的动词,而间接宾语从句是指宾语从句作为双宾语中的间接宾语。

在使用宾语从句时,我们需要注意正确选用引导词以及合理使用从句的结构。

本文将就宾语从句的正确引导和使用进行探讨。

一、直接宾语从句的引导词1.连词“that”在大部分情况下,直接宾语从句可以用连词“that”来引导,而且在口语和书面语中都很常见。

例如:Tom said that he would come to the party.Lisa knows that the concert starts at 7 pm.2.连词“if/whether”当宾语从句是对于某事的疑问或选择时,我们可以使用连词“if”或“whether”来引导宾语从句。

其中,“whether”更加正式,适用于正式场合或较为严谨的语境。

例如:Henry asked if/whether Peter had finished his homework.The teacher inquired whether the students had studied for the exam.3.特殊疑问词特殊疑问词可以引导宾语从句,用于询问特定信息。

例如:Can you tell me where the nearest post office is?Do you know how much the tickets cost?二、直接宾语从句的结构直接宾语从句通常由主语、谓语和宾语从句三部分组成。

在引导词后面紧接着宾语从句,不需要使用逗号进行隔开。

例如:I believe that you will succeed.She thinks she is a good singer.三、间接宾语从句的引导词间接宾语从句出现在双宾语动词后面,它告诉我们给予或交付的对象。

whether和if引导名词性从句

whether和if引导名词性从句

whether和if引导名词性从句(要点精讲)whether与if作“是否”讲时,都可以引导名词性从句,两者在用法上有相同之处,但也有不同之处。

一、相同之处1.whether和if表示“是否”时,都能引导宾语从句,这时两者可以互换,常置于see,ask,learn,tell,wonder,doubt,find out等动词之后。

如:He asked me whether/if I could help him. 他问我是否我能帮他。

I want to know whether/if he lives there. 我想知道他是否住在那里。

We don’t know whether/if we should go or stay. 我们不知道我们是否该走还是待着。

2.在be uncertain/doubtful之后,常用whether引导宾语从句,有时也可以用if。

如:We are uncertain whether/if Mary will come. 我们不确定玛丽是否会来。

二、不同之处1.whether可置于句首引导主语从句,而if不能;但如果是it作形式主语,则主语从句中可以用if。

如:Whether he will come is not certain. =It is not certain if/whether he will come.他是否会来是不确定的。

(it作形式主语,则后面的从句中可以用if)2.在宾语从句中,如果从句中有or not时,分两种情况:(1)当whether与or not连成一个词组时,whether不可换用if。

She asked me whether or not I could finish the task in a day. 她问我是否能在一天之内完成这项任务。

I don’t know whether or not they will come for our help. 我不知道他们是否会来帮我们。

whether/ if及疑问词引导的宾语从句上一个模块中我们学习了that引导的宾语从句,本模块我们学习whether / if 引导的宾语从句和疑问词引导的宾语从句。

一、whether / if引导的宾语从句
当一般疑问句充当句中的宾语时,用连词whether或if引导,连词在从句中不充当任何句子成分,意为“是否”,不可省略。

当宾语从句中没有or not时,whether和if都能用;但当宾语从句中有or not时,只能用whether。

另外,充当宾语从句的一般疑问句要变为陈述句语序。

如:
Will s he go to Beijing tomorrow? I don’t know.
→I don’t know if / whether she will go to Beijing tomorrow.
Will David move to our city or not? She asked.
→She asked whether David will move to our city or not.
二、疑问词引导的宾语从句
当特殊疑问句充当句中的宾语时,由原来的疑问代词what, who, which等或疑问副词when, where, how, why等作为连接词,这些词在宾语从句中充当一定的句子成分,都有各自的词义,不可省略。

另外,充当宾语从句的特殊疑问句要变为陈述句语序。

如:
What is his sister going to do? I ask Jack.
→I ask Jack what his sister is going to do.
When did she arrive in Beijing? I want to know.
→I want to know when she arrived in Beijing.
Where did you buy the beautiful scarf? Could you tell me?
→Could you tell me where you bought the beautiful scarf?
三、whether / if及疑问词引导的宾语从句的时态
我们在使用这两类从句的过程中,当主句的谓语动词是一般现在时的时候,宾语从句的谓语动词可根据需要使用适当的时态;当主句的谓语动词是一般过去时的时候,宾语从句的谓语动词常用相应的过去时态;但当宾语从句表述的是客观真理时,不管主句的谓语动词是何种时态,该从句须用一般现在时。

如:
I want to know whether / if your brother went to the zoo yesterday.
Susan asks whether / if she can go to the school a fter eight o’clock. He asked me what I was doing at that time.
The little boy asked whether / if all the planets go around the sun. 【运用】将下列汉语句子翻译成英语。
