由what、how、if引导的宾语从句
宾语从句间接引语
应注意的几个问题:
1. 宾语从句可放在形容词后。常用形式是“be+形容词+宾语从句” I am glad you like it .
2. 宾语从句与主句时态的一致。 1)主句是现在(或将来)时态时,宾语从句可根据实际需要用 不同的时态。如: He says Mary is playing with the cat . He says Mary often plays with the cat. He says Mary will play with the cat. I think he left yesterday morning. 2) 主句时态是一般过去时,从句要用过去时态的某种形式。 He said Mary was playing with the cat. He said he hoped to be back soon..
▪ 注意:当从句所表示的是客观事实或客观真理时,该从句都用 一般现在时,不用过去时。如: He said light travels much faster than sound.
3. 宾语从句中的否定转移。如果主句谓语动词是think , believe suppose 等,而从句的意思是否定的,这时主句的谓语动词用 否定式,从句用肯定式。如:

宾语从句 宾语从句就是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. 1. 作动词的宾语 (1) 由that引导的宾语从句(that 通常可以省略),例如: I heard that be joined the army. (2) 由what, whether (if) 引导的宾语从句,例如: 1) She did not know what had happened. 2) I wonder whether you can change this note for me. (3) 动词+间接宾语+宾语从句.例如: She told me that she would accept my invitation. 2. 作介词的宾语 例如:Our success depends upon how well we can cooperate with one another. 3. 作形容词的宾语 例如:I am afraid (that) I’ve made a mistake. That 引导的从句常跟在下列形容词后作宾语: Anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等.也可以将此类词后的that 从句的看作原因状语从句. 4. It 可以作为形式宾语 It 不仅可以作为形式主语,还可以作为形式宾语⽽真正的宾语that 从句则放在句尾,特别是在带复合宾语的句⼦中. 例如: We heard it that she would get married next month.. 5. 后边不能直接跟that 从句的动词 这类动词有Allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等.这类词后可以⽤不定式或动名词作宾语,但不可以⽤that引导的宾语从句.例如: I admire their winning the match. (right) I admire that they won the match. (wrong) 6. 不可⽤that从句作直接宾语的动词 有些动词不可⽤于“动词+间接宾语+that从句“结构中,常⻅的有Envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等.例如: He impressed the manager as an honest man. (right) He impressed the manager that he was an honest man. (wrong) 7. 否定的转移 若主句谓语动词为Think, consider, wuppose, believe, expect, fancy, 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.例如: I don’t think this dress fits you well.(我认为这件⾐服不适合你穿.) 状语从句 (Adverbial Clause) ⼀状语从句的种类 § 1状语从句的种类 ⽤来修饰谓语动词、其它动词、定语、状语或整个句⼦的从句叫做状语从句.状语从句可分为: 1.时间状语从句;(adverbial clause of time) 2.地点状语从句;(adverbial clause of place) 3.原因状语从句;(adverbial clause of cause) 4.条件状语从句;(adverbial clause of condition) 5.⺫的状语从句;(adverbial clause of purpose) 6.让步状语从句;(adverbial clause of concession) 7.⽐较状语从句;(adverbial clause of comparison) 8.程度状语从句;(adverbial clause of degree) 9.⽅式状语从句;(adverbial clause of manner) 10.结果状语从句.(adverbial clause of result) §2状语从句的时态特点 ⼀般情况下,时间和条件状语从句的谓语动词⼀般⽤“⼀般现在时”表⽰“⼀般将来时”,⽤“现在完成时”表⽰“将来完成时”.例如: I will call you as soon as I arrive in Beijing. 我⼀到北京就给你打电话.(这是由as soon as引导的时间状语从句,从句中的谓语动词arrive是⼀般现在时,表⽰⼀般将来时,决不可⽤will arrive) As soon as I have finished this work, I will go home. 我⼀完成此⼯作,就回家.(从句中的谓语动词⽤现在完成时have finished,表⽰将来完成时,决不可⽤will have finished) If he comes back, please let me know.如果他回来了,请通知我.(从句中的谓语动词⽤comes back,表⽰⼀般将来时,决不可⽤will come back) ⼆时间状语从句 §3时间状语从句(adverbial clause of time) 1.由when, while, as引导的时间状语从句.例如: When you think you know nothing, then you begin to know something.当你以为⾃⼰⼀⽆所知的时候,你就是在开始知道⼀些事物了. When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候,它在⽣⻓,它感到压抑,它蓄存着这么⼀种爆炸性⼒量,⼀旦冒出,它就会炸破⼀切! Strike while the iron is hot. 趁热打铁. Will you watch my clothes while I have a swim. 我游泳的时候,请你照看⼀下我的⾐服. You can feel the air moving as your hand pushes through it. 当你的⼿在空⽓中挥动的时候,你就能感觉到空⽓在流动. Our headmaster laughed as she spoke.我们的校⻓边谈边笑. 【区别】when, while和as的区别:when引导的从句的谓语动词可以是延续性的动词,⼜可以是瞬时动词.并且when有时表⽰“就在那时”.例如: When she came in, I stopped eating.她进来时,我在吃饭.(瞬时动词) When I lived in the countryside, I used to carry some water for him.当的住在农村时,我常常为他担⽔.(延续性的动词) We were about to leave when he came in.我们就要离开,就在那时他进来了. While引导的从句的谓语动作必须是延续性的,并强调主句和从句的动作同时发⽣(或者相对应).并且while有时还可以表⽰对⽐.例如: While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词,wasreading和was watching同时发⽣) I like playing football while you like playing basketball.我喜欢踢⾜球,⽽你喜欢打篮球.(对⽐) As表⽰“⼀边……⼀边”,as引导的动作是延续性的动作,⼀般⽤于主句和从句动作同时发⽣;as也可以强调“⼀先⼀后.例如: We always sing as we walk.我们总是边⾛边唱.(as表⽰“⼀边……⼀边”) As we was going out, it began to snow.当我们出⻔时,开始下雪了.(as强调句中两个动作紧接着先后发⽣,⽽不强调开始下雪的特定时间) 2.由before和after引导的时间状语从句.注意before引导的从句不再⽤否定式的谓语,并且当before引导的从句位于主句之后,有时译成“就,才”.还要注意主句和从句之间的时间关系.当主句⽤将来时,从句总是⽤现在时;如果before引导的从句谓语⽤的是过去时,则主句动词多⽤过去完成时,这样以便体现动作发⽣的先后.After表⽰主句动作发⽣在从句动作之后.主句和从句的动作的时间关系正好与before引导的从句相反.例如: It will be four days before they come back. 他们要过四天才能回来. Einstein almost knocked me down before he saw me.爱因斯坦⼏乎把我撞倒才看到我. My father had left for Canada just before the letter arrived.我⽗亲恰好在信到之前去加拿⼤了. They had not been married four months before they were divorced. 他们结婚还不到四个⽉就离婚了. After you think it over, please let me know what you decide.你仔细考虑过以后,告诉我你是怎样决定的. After we had finished the work, we went home.完成⼯作之后,我们回家了.(从句⽤过去完成时,主句⽤⼀般过去时) 3.由till或until引导的时间状语从句.till和until⼀般情况下两者可以互换,但是在强调句型中多⽤until.并且要注意的是:如果主句中的谓语动词是瞬时动词时,必须⽤否定形式;如果主句中的谓语动词是延续性动词时,⽤肯定或否定形式都可以,但表达的意思不同.例如: I didn't go to bed until(till) my father came back.直到我⽗亲回来我才上床睡觉. It was not until the meeting was over that he began to teach me English.直到散会之后他才开始教我英语. I worked until he came back.我⼯作到他回来为⽌. I didn't work until he came back.他回来我这才开始⼯作. Please wait until I arrived.在我到达之前请等我. 4.由since引导的时间状语从句. since引导的从句的谓语动词可以是延续性的动词,⼜可以是瞬时动词.⼀般情况下,从句谓语动词⽤⼀般过去时,⽽主句的谓语动词⽤现在完成时.但在It is +时间+since从句的句型中,主句多⽤⼀般现在时.例如: I have been in Beijing since you left. ⾃从你离开以来,我⼀直在北京了. Where have you been since I last saw you? ⾃上次我和你⻅⾯以后,你到哪⾥去了? It is four years since my sister lived in Beijing. 我妹妹不在北京住有四年了. It is five months since our boss was in Beijing.我们⽼板离开北京有五个⽉了. 5.由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引导的时间状语从句.这些连词都表⽰“⼀……就”.例如: I will go there directly I have finished my breakfast. 吃完早饭,我⽴即到那⾥去. The moment I heard the news, I hastened to the spot.我⼀听到消息,⻢上赶到了出事地点. As soon as I reach Canada, I will ring you up. 我⼀到加拿⼤,就给你来电话. 【注意】hardly(scarcely, rarely)…when / before, no sooner…than相当于as soon as之意.主句⽤过去完成时,从句⽤⼀般过去时.当hardly, scarcely, rarely和no sooner位于句⾸时,主句应⽤倒装语序.例如: He had no sooner arrived home than he was asked to start on another journey. 他刚到家,就被邀请开始另⼀旅程. No sooner had the sun shown itself above the horizon than he got out of bed to commence work.太阳刚从地平线上升起,他就起床劳动去了. Hardly had I sat down when he stepped in.我刚坐下,他就进来了. He had hardly fallen asleep when he felt a soft touch on his shoulder.这个阿拉伯⼈刚要⼊睡就感到肩膀上被轻轻⼀触. 6.由by the time引导的时间状语从句.注意时态的变化:在⼀般情况下,如果从句的谓语动词⽤⼀般过去时,主句的谓语动词⽤过去完成时;如果主句的谓语动词⽤⼀般现在时,主句的谓语动词⽤将来完成时.例如: By the time you came back, I had finished this book.到你回来时,我已经写完这本书了. By the time you come here tomorrow, I will have finished this work. 你明天来这⼉的时候,我将已经完成此⼯作了. 7.由each time, every time和whenever引导的时间状语从句.例如: Each time he came to Harbin, he would call on me. 他每次来哈尔滨,总是来看我.

You grow younger every time I see you. 每次遇到你,⻅你更年轻了. 8.由as long as和so long as引导的时间状语从句.这两个连词表⽰“有多久……就多久”.例如: You can go where you like as long as you get back before dark. 你可以随意到哪⾥去,只要在天⿊以前回来就⾏. I will fight against these conditions as long as there is a breath in my body! 只要我⼀息尚存,我就要反对这种境况. 三地点状语从句 §4地点状语从句 (adverbial clause of place) 地点状语从句⼀般由连接副词where, wherever等引导,已经形成了固定的句型,例如: 句型1:Where+地点从句,(there)+主句. 【注意】此句型通常译成“哪⾥……哪⾥就……”;主句在从句后⾯时,there可⽤可不⽤;如果主句在从句的前⾯时,⼀般都不⽤there.例如: Where there is no rain, farming is difficult or impossible.在没有⾬⽔的地⽅,耕作是困难的,或根本不可能的. They were good persons. Where they went, there they were warmly welcomed. 他们都是好⼈.因此他们⾛到哪⾥都受到热烈欢迎. You should have put the book where you found it. 你本来应该把书放回原来的地⽅. Where the Communist Party of China goes, there the people are liberated.哪⾥有了中国共产党,哪⾥⼈⺠得解放. 句型2:Anywhere/ wherever+地点从句,+主句. 【注意】anywhere本⾝是个副词,但是,常可以引导从句,相当于连词,意思相似于wherever, anywhere 引导的从句可位于主句之前,也可以位于主句之后. ⽽wherever本⾝就是个连词,表⽰“在何处,⽆论何处”.例如: Wherever the sea is , you will find seamen.有海就有海员.猜你喜欢。

例如:What do you want? 你想要什么?(what在宾语从句中作主语)He asked me what I wanted. 他问我想要什么。
(what在宾语从句中作主语)Tell me what you think. 告诉我你怎么想。
(what在宾语从句中作宾语)I wonder what he is doing. 我想知道他在做什么。

宾语从句的用法
宾语从句的用法一、定义宾语从句是名词性从句的一种。
在主从复合句中充当宾语,位于及物动词、介词或复合谓语之后的从句称为宾语从句。
因此,有人把宾语从句分为动词后的宾语从句、介词后的宾语从句和形容词后的宾语从句。
如:动词后:I don't know when he came back.介词后:I'm thinking about who is the right person for the position.形容词后:He's sure she will win the game.二、引导词能够引导宾语从句的词语主要有:thatif/whetherwho/whom/whose/which及其-ever结构how/why/when/where及其-ever结构what(一)that引导的宾语从句that引导宾语从句时,就是起着连接作用,不在从句中作成分。
如:I think that it's very interesting to experience a different culture.He didn't know that he had been to the lecture last night.此时的that经常被省略,所以上面两句可以改为:I think it's very interesting to experience a different culture.Hedidn't know he had been to the lecture last night.需要注意的是,也有that不可省略的情况,常见的有:1、that作learn、suggest、explain、agree、wonder、prove、mean、state、feel、hold等动词的宾语时。
如:She explains that Jack did do the job by himself yesterday.2、一个动词带有两个或两个以上宾语从句时,第一个that 可以省略,第二个that不可以省略。

名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
复合句(宾语从句与状语从句)
宾语从句(The Object Clause)一、在复合句中做宾语的从句叫做宾语从句,它有三种类型。
(一)由that引导的宾语从句。
这种宾语从句中的that本身没有词义在口语或非正式文体中可以省略。
例如:1.I hope(that)he will come tomorrow.我希望他明天来。
2.He said(that)he would study English harder than before.他说他将比以前更努力地学英语。
(二)同连接代词who,whose,what,which和连接副词how,when where引导的宾语从句。
这些连词在句中作成分,有实际意义不能省略。
例如:1.I don't know who he is. 我不知道他是谁。
2.Could you tell me whose room this is? 你能告诉我这是谁的房间吗?3.He asked me which class I was in. 他问我在哪个班。
4.We didn't know when we would meet. 我们不知道我们将在哪儿见面。
5.Please tell me how I can use the computer,will you? 请你告诉我怎样使用计算机好吗?(三)由连词wether或if引导的宾语从句。
例如:1.The teacher asked me if/whether I could answer this question.老师问我是否能回答这个问题。
2.We don't know if/whether he has been to The Great Wall.我们不知道他是否去过长城。
二、宾语从句需要注意的几个问题(一)宾语从句是陈述句不是疑问句,要用陈述句语序。
(二)含有宾语从句的复合句主句是过去时宾语从句要用过去时态——一般过去时,过去进行时,过去将来时和过去完成时。
