宾语从句讲解ppt

有关宾语从句的补充说明 1)、宾语从句的标点由主句决定。 He doesn't know who he is ( . ) Does he know who he is ( ? )
2)、主句的谓语动词是think, believe, imagine, suppose, consider, expect, fancy, guess等, 并且主句的主语是第一人称而且为一般现在时, 从句的否定词一般要转移到主句上来, 其反义 疑问句一般与宾语从句一致. I think he isn’t a student. × I don’t think he is a student. √ I don’t think he is a student. Is he? 如果宾语从句中有某个含有否定意义的形容词 或副词,其反义疑问句要用肯定形式.We find that he never listens to the teacher carefully, does he?
3. 由连接代词Who, whom, whose, which， what 和连接副词 where, how, why, when引 导的宾语从句，这些连接代词和连接副词在宾 语从句中充当某个成分。 例如： Do you know who (whom) they are waiting for? He asked whose handwriting was the best. Can you tell me where the No.3 bus stop is? I don't know why the train is late.

请同学们来看下面这几个句子： I like swimming. 宾语 He has a pen.宾语 My sister wants to be a teacher.宾语 I think he is right.宾语 宾语从句是主从复合句的一种。主从复合句 是由一个主句和一个或一个以上的从句构成的。 主句是复合句的主体，从句仅仅是主句的一个 成分，它从属于主句，不能独立。从句在全句 中充当什么成分，就叫什么从句。宾语从句当 中的从句在全句中作宾语。
一．宾语从句的连接词 1. 由从属连词that引导的宾语从句：that在句 中无词汇意义，在从句中不能充当成分，在 口语中往往省略。例如： He said (that) he wanted to stay at home. She doesn't know (that) she is seriously ill. I am sure (that) he will succeed.
2. 如果主句的时态是一般过去时，宾语从句只能 用相应的过去时态（一般过去时，过去进行时， 过去将来时，过去完成时）。例如： He asked what time it was. He told me that he was preparing for the sports meet. He asked if you had written to Peter. He said that he would go back to the U.S. soon. He said, “Mary is playing with the cat.” → He said Mary was playing with the cat. He said, “he will go back to China soon.” → He said he would go back to China soon
二. 宾语从句的语序 宾语从句的语序应为陈述句的语序。例如： I hear (that) physics isn't easy. I think (that) you will like this school soon. Can you tell me how I can get to the zoo? Please tell me when we'll have the meeting. 考点归纳(2)——宾语从句的语序 宾语从句的语序是陈述句（即主语+谓语）的 顺序。
2.if / whether引导宾语从句。意为是否，仅 起连接作用，if/whether在从句中不作任何成 分。 Could you tell me if/whether it's polite to speak loudly at the table? I don't know if/whether you are right. I don't know whether you are right or not.
考点归纳(1)——宾语从句的连接词 1.that 只起连接作用，在句子中不做句子成 分，在口语中常被省略 2.If 和 whether 起连接作用，不做句子成分。 （注意：与 不定式连用；做介词的宾语；与 or not 连用——用 whether。) 3.疑问词 who、 what 、when、 where 、 whom 、whose 、why、 how 、 which 在句子中既起连接作用，又做句子成 分。
4、当主句为 Could you (please) tell us-----?时， 只表示语气，而不表示过去时态。 考点归纳(3)——宾语从句的时态 1、当主句动词为一般现在时，从句可用所需的 任何时态。 2.当主句动词为一般过去时，宾语从句只能用相 应的过去时态（一般过去时、过去进行时、过去 将来时、过去完成时）。 3.当宾语从句为客观真理时 ，用一般现在时态， 不受主句时态的限制。 4.当主句为 Could you (please) tell us-----?时， 只表示语气，而不表示过去时态。
3. 如果宾语从句所陈述的是客观真理，其时态 常用一般现在时，不受主句时态的限制。例如： Our teacher said that January is the first month of the year. Scientists have proved that the earth turns around the sun. The teacher said, “the moon moves around the sun.” → The teacher said that the moon moves around the sun. He said, “light travels much faster than sound.” → He said light travels much faster than sound.
三. 宾语从句的时态 1. 如果主句的时态是一般现在时，宾语从句该用 什么时态就用什么时态。即，从句可用所需的任 何时态。如： I don’t think (that) you are right. Please tell us where he is. Can you tell me how I can get to the railway station? 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.
