宾语从句的讲解

1、宾语从句的讲解一宾语从句的定义 在句中充当宾语的句子是宾语从句。例如： I hope that I can see you again one day. 我希望有一天我能再见到你。 例句中，动词hope后跟宾语从句，充当hope的宾语，引导词是that。 二不同引导词引导的宾语从句 （一）由that引导的宾语从句 that引导的宾语从句为陈述句。that只起连接作用，在从句中不做句子的成分， 无实意，所以在口语中常被省略。 例：I told him (that） he was wrong. 我告诉他他错了。 试一试： 我希望你明天能够来。_ 我敢肯定你会通过这个考试。_ 注意： 在think,

2、 believe, suppose, 等动词引起的宾语从句中，当宾语从句表示否定时，本身不用否定形式，否定需要前置。 例如： 我认为你做的不对 I dont think that you are right. 试一试： They believe. They wont lose the game. (合成一句) I think that we will be late. (改为否定句) _ (二) 由if/whether引导的宾语从句 由whether(if)引导的宾语从句，实际上是一般疑问句演变而来的。if/whether在句中的意思是“是否”。而且从句原来的疑问语序要成陈述语序。 例如： I

3、 dont know if/whether he lives here. 例句中，if/whether 引导从句he lives here。（从句原来的疑问式是Does he live here?变成陈述式，将助动词does去掉，动词保持原有的单三形式lives） 试一试： Are you a student? (变为陈述式)_ Does your mother get to work by bus? （变为陈述式）_ Has he finished his homework? （变为陈述式）_ Did they go to the park yesterday?（变为陈述式）_ I wond

4、er. Will they come to my party? (合成一句：我想知道他们是否会来。) I dont know. Has he learned English? (合成一句：我不知道他是否学过英语。) The teacher asks us. Did we finish our homework?( 合成一句：老师问我们是否完成了作业。) _ 注意： 只能用whether，不能用if的情况 在介词的后面 例句：Im thinking about whether we should go to see the film. 我正在考虑我们是否该去看电影。Im interested i

5、n whether he likes English我感兴趣的是他是否喜欢英语。 与or not连用时 例句：I dont know whether I have learned this word or not. 我不知道我是否学过这个单词。 在带to的不定式前 例句：We decided whether to walk there. 我们决定了是否步行去那里。 I dont know whether to go我不知去否。 2.区别“如果if 和是否if ” 如果if，引导条件状语从句，遵循主将从现等规则；是否if引导宾语从句。 I dont know if they _ (come) t

6、omorrow. If they _ (come) tomorrow, I will call you. (三) 由特殊疑问词引导的宾语从句 特殊疑问词充当引导词时，在句中即有连接从句的作用，又在句中有一定的含义。同时也要注意从句要从疑问语序变成陈述语序。例如： Do you know when he will come back? 你知道他明天什么时候回来吗？ 例句中，从句when he will come back 为陈述语序，原来的疑问语序是when will he come back? 试一试： How did you get to school? （变陈述语序）_ Where has

7、 he been? （变陈述语序）_ I dont know. What are they looking for?（合成一句） _ He asks me. When does the train usually leave? （合成一句） _ 三宾语从句的时态 1. 主句是一般现在时，从句根据实际情况使用任何时态。 例句：The headmaster hopes that everything goes well. The headmaster hopes that we will win the game. I dont know who came here just now. I don

8、t know if he has finished his homework. 2. 主句是过去时态，从句须用过去的某种形式。 例句：She was sorry that she hadnt finished her work on time. I didnt know if he had finished his homework. The headmaster hoped that we would win the game. 注意：当宾语从句表示的是一个客观真理或者事实时，即使主句是过去时，从句也用一般现在时态。 例句：The teacher told his class that li

9、ght travels faster than sound. 四宾语从句的语序 前面的用法中已经介绍到了，无论主句是陈述句还是疑问句，宾语从句都必须使用陈述 语序：即“引导词+主语谓语”的句式。 注意一些特殊情况： 1.引导词本身就是主语, 多为what 或who 或whose引导的从句 例如： I wonder who is in the room. （who 在从句中本身就充当主语） Can you tell me whose book is on the desk? （whose book 在从句中本身就充当主语） He asked me who helped us. （who 在从句中

10、本身就充当主语） 2. 句型whats the matter ，whats the trouble等常被看成陈述语序，不变。 We dont know whats the matter with her. 五宾语从句转化为简单句 1. 由特殊疑问词引导的宾语从句，如果主句和从句的主语一致时，可以转化成 “特殊疑问词+ to do”。例如： I dont know how I can learn English well. _ He wonder when he should attend the meeting. _ 2. 当主句谓语动词是hope， decide， wish， choose，

11、 agree等，且宾语从句的主语与主句主语一致时，宾语从句可简化为v. + to do的结构。例如： Li Ming hopes he will be back very soon. Li Ming hopes to be back very soon. We decided that we would help him. _ 3. 当主句的谓语动词是tell, order（命令）等时，如果主句和从句的主语不一致，宾语从句可简化为 v.+ sb. to do的结构。例如： The headmaster ordered that we should start at once. The head

12、master ordered us to start at once. My mother told me that I couldnt go out. _ 4.动词see, hear, find等词后面的宾语从句可转化为“v+ sb. doing的结构。例如： Liu Ping found that there was a wallet lying on the ground. Liu Ping found a wallet lying on the ground. I heard that a bird was singing in the tree. _ 5. 动词seem后的宾语从句，

13、也可以用不定式（短语）来简化. It seems that he is unhappy. He seems to be unhappy. It seemed that the boys were going to win. The boys seemed to win. 6. 动词find后的宾语从句，也可以转化为简单句 I found that it was difficult to learn English well. _ They found that the box was very heavy. _ 4 附: 直接引语变间接引语的用法 【概念】 直接引语是指直接引用别人的原话，通常

14、置于引号之内。间接引语是指用自己的话转述别人的话或意思，多用宾语从句的形式来表达。 一人称变 ( 一随主，二随宾，第三人称不更新 ) He said, “Im good at English.” He said (that) he was good at English. The woman said to Jack, “You are a good boy” The woman told Jack (that) he was a good boy. He said,” Jack is a good student.” He said (that) Jack was a good studen

15、t. 练习： 1. She said, My brother wants to go with me._ 2. The teacher told me,” You are hardworking.” _ 3. She said. He will go to see his friend._ 4.The teacher said,” You are hardworking.” _ 二时态变 He said, “Im good at English.” He said (that) he was good at English. Maria said, “ Lily is doing her ho

16、mework.” Maria said that Lily was doing her homework. She said. He will go to see his friend.She said (that) he would go to see his friend. He told me, “ He saw Mary in the house.” He told me that he had seen Mary in the house. The man told us, “ I have been to Beijing.” The man told us that he had

17、been to Beijing. 总结： 一般现在时 变成_ 现在进行时 变成_ 现在完成时 变成_ 一般过去时 变成_ 一般将来时 变成 _ 特殊：真理时态不变 Our teacher told us, “ The earth goes around the sun.” _ 三句型变 1. 直接引语是陈述句，间接引语应改为由that引导的宾语从句。(that 可省) She said, Our bus will arrive in five minutes. _ 2. 直接引语是一般疑问句，间接引语应改为由whether或if引导的宾语从句. 如：He said, Can you swim,

18、 John? _ 3. 直接引语是特殊疑问句，间接引语应该改为由特殊疑问词引导的宾语从句（宾语从句必须用陈述句语序）。 She asked me, When do they have their dinner? She asked me when they had their dinner. 4. 直接引语是祈使句，间接引语应改为： 肯定：tell(ask, order,等) sb. to do sth. 否定：tell(ask, order等) sb. not to do sth. Dont make any noise, she said to the children. _ Bring
