宾语从句是什么?怎么用?
一.宾语从句的定义 置于动词、介词等词性后面起宾语作用的从句叫宾语从句.宾语从句的语序必须是陈述语序.谓语动词、介词、动词不定式,v.-ing形式后面都能带宾语从句.有些形容词(afraid,sure,glad等)之后也可以带宾语从句.二.宾语从句中引导词的用法 在复合句中作主句的宾语,引导词有:连词:that (that 常可省略),whether,if 代词:who,whose,what ,which 副词:when ,where,how,why 等.(一)that引导的宾语从句(在非正式场合that可以省略) 可跟that从句做宾语的动词有:say,think,insist,wish,hope,demand,imagine,wonder,know,suppose,see,believe,agree,admit,deny,expect,explain,order,command,feel,dream,suggest,hear,mean,notice,prefer,request,require,propose,declare,report等.例句:The boy believes that he will travel through space to other planets.注意事项:当主句谓语动词是 think,believe,suppose,expect 等词,而宾语从句的意思是否定时,常把否定转移至主句表示.例句:I don’t think it is right for him to treat you like that.在以下情况中that不能省略 1.当句中的动词后接多于两个由that引导的宾语从句时,第一个that可省,但后面的that不可省.例句:He said (that) you were too young to understand the matter and that he was asked not to tell you.2.当主句的谓语动词与that宾语从句之间有插入语时,that一般不可省.例句:Just then I noticed,for the first time,that our master was wearing his fine green coat and his black silk cap.3.当that从句是双宾语中的直接宾语时,that不可省.例句:I can’t tell him that his mother died.注意事项:许多带复合宾语的句子,that引导的宾语从句经常移到句子后部,而用it作形式宾语.例句:I find it necessary that we should do the homework on time.(二)由whether,if 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.意思是“是否”.宾语从句要用陈述句语序.一般说来,在宾语从句中whether与if可以互换使用,但在特殊情况下if与whether是不能互换的.例句:I wonder whether(if) they will come to our party.只能用whether,不能用if引导的宾语从句 1.在带to的不定式前 例句:We decided whether to walk there.2.在介词的后面 例句:I’m thinking of whether we should go to see the film.3.在动词后面的宾语从句时 例句:We discussed whether we had a sports meeting next week 4.直接与or not连用时 例句:I can’t say whether or not thet can come on time.只能用if不能用whether引导的宾语从句 1.if引导条件状语从句,意为“如果” 例句:The students will go on a picnic if it is sunny.2.if引导否定概念的宾语从句时 例句:He asked if I didn’t come to school yesterday.3.引导状语从句even if(即使)和as if(好象)时 例句:He talks as if he has known all about it.(三)连接代词和连接副词引导的宾语从句 这样的宾语从句实际上是由特殊疑问句变化而来的,宾语从句要用陈述句语序.用于这
