宾语从句
一、 概述:
宾语从句是在复合句中充当宾语成分的从句。可以分为动词的宾语从句,介词的宾语从句和形容词的宾语从句。
二、三种宾语从句讲解
1. 动词的宾语从句
· 由连词that/if/whether引导 这三个连词起连接作用,不作任何成分
[1] that引导 可以省略 无实际意义
如: He says that he can’t play basketball.他说他不会打篮球。
[2] whether/if 引导 不可以省略 翻译成“是否”
如:Everyone wonders if/whether there are aliens in the world.
每个人都想知道世界上有没有外星人。
注意: 一般if和whether可以互换,以下几种情况除外。
1) 和or not连用时。
如:I don’t know whether I can go home or not.
我不知道我是否可以回家。
2)作介词的宾语从句时。
如:People are interested in whether you will come to the party.
人们对你来不来派对感兴趣。
3)在动词不定式前时。
如:I don’t know whether to go swim this Sunday.
我不知道这周日要不要去游泳。
[3] 连接代词引导的宾语从句
what/which/what 等引导宾语从句时,在宾语从句中充当主语、宾语、表语、定语等成分,不可省略。
举例:
· who在从句中作主语
I don’t know who knock my books onto the floor.我不知道谁把我的书撞倒了地上。
· which在从句中作定语
Can you tell me which boy is your sister?你能告诉我哪个是你姐妹吗?
· what在从句中作表语
She doesn’t know what his mood is. 她不知道他的心情是什么。
[4] 连接副词引导的宾语从句
how, where, when, why等引导宾语从句,并充当状语。不可省略。
举例:
· where作地点状语
Do you know where she lives? 你知道她住哪儿吗?
· how作方式状语
Can you tell me how I get to the subway station? 你能告诉我怎么去地铁站吗?
· when作时间状语
I don't know when she will come.我不知道她什么时候来。
2. 介词后的宾语从句
She is always thinking of how she can do more for others.
她总想着如何才能为别人做得更多。
We are talking about whether we admit students into our club.
我们正讨论是否让学生加入俱乐部。
3. 形容词后的宾语从句
常用形容词:glad,pleased,sure,certain,happy,sorry,afraid,satisfied,surprised
I'm sorry I'm late. 对不起,我迟到了。
I'm afraid he isn't in at the moment.恐怕他此刻不在家。
I’m sure I will pass the exam. 我坚信我会通过考试。
三、注意事项
1. 宾语从句语序
必须是陈述句语序,即“主语+谓语”。全句语序为“主句+引导词+主语+谓语+其他”
He asked me what I did yesterday . 他问我昨天干什么了。
Do you know why winter is colder than summer?你 知道为什么冬季比夏季冷吗?
2. 宾语从句的否定转移。
条件;主句中主语为第一人称,谓语动词为表示“认为“的词,主句为一般现在时。
要求:把宾语从句的否定词转移到主句中
常见的需要否定转移的动词:think、believe、suppose、expect
I don't think he is a good student.
I don't believe she will come.
We don't suppose he has finished the work.
3. 宾语从句的时态
口诀:“主过从必过,主现从不限,真理永一现”
· 主句是过去式,从句也用相应的过去式
He said there were no classes yesterday afternoon. (从句是一般过去时)
他说昨天下午没有课。
He said that he was going to take care of the baby. (从句是过去将来时)
他说他会去照看这个婴儿。
· 主句是现在式,从句用任何适当时态
She says (that)she works from Monday to Friday. (从句为一般现在时)
她说她周一至周五上班。
She says (that) she will leave a message on his desk. (从句是一般将来时)
她说要在桌子上留个便条。
She says (that) she has never been to Mount Emei. 。(从句是现在完成时)
她说她从来没有去过峨眉山
· 客观真理、事实客观用一般现在时
He said that light travels much faster than sound. (客观事实用一般现在时)
他说光比声音传播得快。
