宾语从句
一、定义:
用作宾语的从句叫宾语从句。宾语从句可以用连词that,连接代词who,whom,what,which;连接副词 how,when,where以及if和whether引起。连接代词和连接副词在宾语从句中作一相应的句子成分,if或whether表示疑问,而that没有意义仅起连接作用。
二、宾语从句的分类:
1. 作动词的宾语从句:
如:Everyone knows that he is a good student.
He wondered how the pyramids were built.
2. 作介词宾语:
如:This depends on how hard you work.
Is there anything wrong in what I said?
3. 作形容词的宾语:
如:They are confident that they can do the job well.
I am not certain whether the train will arrive on time.
三:使用宾语从句要注意的问题:
1. 宾语从句引导词that的省略:
在非正式场合下,that在引导宾语从句时,可以省略。
如:I think (that) you are right.
2. 形式宾语it:
如果宾语从句后面跟有补语,要用形式宾语it来代替,而将从句放到补语的后面去。如:He has made it clear that the meeting will not be postponed.
I heard it said that that factory was founded in 1901.
3.宾语从句的时态呼应:
如果主句的谓语是过去时,宾语从句的时态要按照时态呼应规则进行相应的调整。但是若宾语从句表示的是客观真理或自然观念,其谓语时态仍用一般现在时。
如:He said that he had left his umbrella in the library.
The teacher told the students that the Pacific Ocean is the largest ocean in the world.
4. 宾语从句否定意义的转移:
在think, believe, suppose, expect 等动词所根的宾语中,如果从句谓语是否定的,一般要将否定词not转移至主句谓语上去,而将从句宾语变为肯定形式。
如:I don’t think he has time to play chess with you.
I don’t suppose it is the rush hour yet.
5.一些动词接的宾语从句通常要用虚拟语气:
一般说来,在一些表示坚持(insist),命令(order,command),建议(suggest,advise),要求(require,demand) 等动词之后的宾语从句中,谓语一般要用“should +动词原形”(其中的should在美国英语中常省略,但是引导从句的that通常不省略):
如:She suggested that we (should) leave early.
He ordered that the medicine (should) be sent by a special plane.
6.whether 与 if
引导介词宾语从句时,只能用 whether,不用if;与“or not”连用时,一般用whether,不用if。
如:I am interested in whether he'll go abroad.
We don't know whether he will come or not.
7.宾语从句的语序
连接词后面为陈述语序。
如:I don’t know what your name is.
8.直接引语变为间接引语
间接引语的使用应注意选择合适的动词。陈述用say/tell,疑问用ask/wonder,而祈使用 tell/order,建议用advise/suggest。注意这些动词后面的结构和语气。
如:“Could you get some tea for me?” Mr.Blake said to his wife.
→Mr. Blake asked his wife whether she could get some tea for him.
“Shall we go dancing tonight?”John said.
→John suggested they should go dancing tonight.
