宾语从句专练

宾语从句专练 宾语从句在复合句中作主句的宾语。宾语从句通常由下面一些词引导。 1、由that引导(that在口语或非正式文体中常省略)。 2、由what , when , where, which, who, how ,why等连接代词或连接副词引导。 3、由连词whether或if引导(口语中常用if)。 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” e.g. 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.. 3)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: I don’t think you are right. 我认为你不对。 4、将普通的特殊疑问句变成宾语从句时,从句的语序要由疑问句变成陈述句的语序。 When will the meeting begin?-------I want to know when the meeting will begin. 5、将普通的一般疑问句变成宾语从句时,则用if /whether连接,同时变成陈述句语序。 Are you an English teacher ?-------He asked if I was an English teacher. 在下列情况下只能用whether 1)介词后的宾语从句 I’m thinking about whether we should go fishing. 2)宾语从句提前时 Whether this is true or not, I can’t say. 3)直接与or not连用时 I don’t know whether or not he was ready. 4)在带to 的动词不定式前 She has n’t decided whether to go or not. if也可引导条件状语从句,表示“如果”(主将从现,主过从过)。比较: I don’t know if he will come. If he comes ,I will tell you. 6、在变宾语从句时,要注意以下几点。1)连接词 2)人称 3)语序 4)时态 5)标点 练习 1.用所给动词的适当形式填空。 1)I know that the young man ______________(come) to the village every Saturday. 2).
