Grammar宾语从句与表语从句名词性从句在复合句中起名词作用的从句叫做名词性从句。
名词性从句的作用相当于名词,因此主语从句、表语从句、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。
主语从句: Who will win the match is still unknown. 宾语从句: I want to know what he has told you.表语从句: The fact is that we have lost the game.同位语从句: The news that we won the game is exciting.引导名词性从句的连接词可分为三类:连接词 (不充当从句的任何成分 ):that ,whether ,if连接代词:what, who, whom, whose, which, wh+ever连接副词: when ,where ,how ,whyObject Clauses宾语从句请对应写出句子成分I know him.()()()I know who he is.()()()请用横线画出下面句子的宾语从句部分。
1、I know him.2、Do you have the time?3、I think that she is beautiful.4、Why don’tyou pay attention to me?总结:宾语通常位于谓 _____________或者 _____________后一、宾语从句的概念:宾语从句在复合句中作主句的宾语。
位置:通常放在主句谓语动词(及物动词)或介词之后。
句子结构:主句+连词 (引导词 )+ 宾语从句e.g.She asked if these answers were right.We can learn what we do not know.He will talk to us about what he saw in the U.S.A.I don ’ t knowwhere we will hold the meeting.通过观察,我们可以知道宾语从句的语序用陈述语序:接 +主 ++其他成分:1)Could you tell me______.A. you will get here whenB. when will you get hereC. get here when you willD. when you will get here2)Mother asked his son what ______for lunch at school.A. did he hadB. does he hadC. he hasD. he had3)Pointing to the young plant, he asked me ____ that was the one we had seen in the picture.A. whatB. ifC. whereD. how二、接1、从属接 (不充当从句的任何成分 ): that ,whether ,if1)、 I hear (that) he will be back in an hour.2)、I want to know if /whether he will go to the park with us注:1、由 that 引的述句性的从句,在很多如say, think, wish , hope, see, believe, agree, expect, hear , feel等后。
宾语从句和表语从句用法归纳宾语从句和表语从句是名词性从句的重要组成部分,也是高考的重点。
今天我们先谈谈这两种从句。
一、宾语从句I. 宾语从句的引导词引导宾语从句的词有:连词that, if, whether;连接代词who, whom, whose, what, which;连接副词when, where, how, why等。
(1)连词that在宾语从句中不充当任何成分,也无任何意义,可以省略;其它带有疑问意义的连接词则不能省略。
如:I know (that) he is a good teacher.He doesn’t know who first discover-ed America.(2)whether与if①二者都有“是否”的意思,一般可以换用,但在介词之后,不定式之前,与or not连用时,只能用whether。
如:It all depends on whether they will support us.She stood in the doorway, unable to decide whether to go in.②引导否定的宾语从句时只能用if。
如:I wonder if he won’t hurt the feeling of his girlfriend.③另外引导主语从句(放在句首)、表语从句、同位语从句时,也只能用whether,不能用if。
(3)what在宾语从句中,引导词what具有两种含义:①保留疑问,即“什么”的意义;②相当于“all / everything that”,常译成“……的(东西或事)”。
II. 宾语从句注意事项(1)宾语从句无论用哪种连接词来引导,语序都必须用陈述语序,尽管有时有疑问意义。
如:Do you know when the lesson will begin?(2)要注意主、从句时态的一致和相应变化。
如:①当主句是一般现在时或一般将来时的时候,从句可根据说话人的需要选择适当的时态。
