第17讲宾语从句
高职考纲中宾语从句测试的重点是:掌握宾语从句的基本用法
1. 掌握宾语从句的各不同引导词的用法。
2.掌握宾语从句的语序。
3.掌握宾语从句中,主句与从句在时态上的相互呼应。
4.掌握由it作形式宾语的宾语从句。
宾语从句在复合句中作宾语,从句放在主句谓语动词(及物动词),介词或某些形容词之后,前后不用逗号分开。如
I don’t know if/whether he will come tomorrow.
She was interested in what I said.
二、宾语从句的引导词
1、由连词that 引导的述句性的宾语从句,在很多动词如say, think, hope, see, believe, expect, hear 等动词后。连词that只起连接作用,在从句中不做句子的成分,也无词汇意义,在口语中常被省略。
He says (that) his father is a boss.
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。如:I find it necessary that we should learn English well.
2、由连词if、whether 引导的宾语从句表示“是否……”。Whether,if 在从句中不做句子的成分,一般情况下,whether和if 可以替换,但在特殊情况下if与whether是不能互换的。
I wonder whether (if) they will come to our party.
当whether与or not连用时whether不可换用if。在介词后面只能用whether,不能用if。在动词不定式之前,只能用whether,不能用if。
He doesn't know whether to stay or not.
3、由wh-引导的宾语从句。连接代词who,whom,whose, what, which,和连接副词when, where, why, how 等连接的宾语从句,它们在句中既有连接从句的作用,又在句中充当句子的成分。
Do you know which film they are talking about? (which在从句中做定语)
I don’t know where he lives. (where在从句中做地点状语)
三、宾语从句的语序
宾语从句属于名词性从句,它的语序必须是述语序,即连接词+主语+谓语+其他成分
如:I believe that they will come soon.
He asked me whether I was a teacher.
They wanted to know what they can do for us.
四、宾语从句的时态。
宾语从句的时态受主句的限制,从句根据实际情况而定。
主句是一般过去时态,从句用相应的过去的时态。如果从句的动作发生在主句之前,则从句要用过去完成时态。
如:She says that she is a student.
She said that she was a student.
She says that she will fly to Japan in a week.
She said that she would fly to Japan in a week.
She says that she has finished her homework already.
She said that she had finished her homework already.
注意事项:如果宾语从句说的是客观真理、自然现象或事实时,这时宾语从句要用一般现在时态。
如:The teacher said that the earth goes round the sun.
He told me that Japan is an island country.
Could you tell me…是用来征询对方的意见,语气委婉,并不表示过去。
如:Could you tell me when we will visit the farm?
五.其他常见用法
否定转移问题在think,believe,suppose,consider等动词所跟的宾语从句中,如果从句表示的是否定意义,一般要将否定词移至主句的谓语上,而将从句变为肯定形式。如:I’m sorry , but I don’t think I know you. 很抱歉,我想我并不认识你。
I don’t believe that the man is killed by Jim. 我认为那个人不是吉姆所杀的。
例1(2008年,)
He asked me ______ we could go to Beijing to watch the game by plane.
A. that
B. if
C. how
D. what
[解析]考查宾语从句引导词。根据主句可以推出宾语从句表达的是不确定的语气,所以排除选项A;宾语从句中没有缺少与how和what相对应的句子成分,故本题应选B。
例2(2008年,)
—Do you know ____?
—Sorry, I don't know.
A. where does Jimmy work
B. where Jimmy works
C. how does Jimmy go to work
D. what does Jimmy do
[解析] 考查述句语序。A、C、D用的是疑问句语序,所以该题的正确答案应为B。
例3(2008年,)
—Do you know ____ for Shanghai last night?
—At 9:00.
A. what time he leaves
B. what time does he leave
C. what time he left
D. what time did he leave
[解析] 考查述句语序和时态。根据语序,可以排除选项B和D,从时间状语last night可以推断宾语从句应该使用一般过去时,故本题的正确答案是C。
例4(2009年,平湖)
I think _____ best that you should stay here.
A. this
B. that
C. it
D. what
[解析] 考查it引导的形式宾语。that后面引导的是宾语从句,it 起形式宾语的作用,this, that,
