宾语从句连接词有哪些英语(宾语从句的连接词的用法)

导语：高中英语语法一点就通之宾语从句连接词详解

一 宾语从句的概念

从句在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）或介词之后。

经典例句 1 Anne said that she didn't want to set down a series of facts in a diary.

2 The writer asks us if a friend always has to be a person.

二 宾语从句三要素

引导词（连接词）、语序和时态

三 引导词

1 由从属连词 that 引导的宾语从句

例句 1).I hear (that) he will be back in an hour.

2). He said (that)he missed us very much.

小结：that 在句中无词汇意义，在从句中不能充当成分，在口语当中往往省略

注意：that 不可以省略的情况

1）当that作介词except, in 宾语时

•They believe in that she must still be single.

•I know nothing about him except that he is living in Beijing.

（2）用it做形式宾语的宾语从句时

（ it常可以放在动词think, find, consider, believe, feel, make等后作为形式宾语，而真正的宾语——that从句则放在句尾）

•I think it necessary that you should read English aloud.

•We heard it that she would get married next month.

2 由从属连词 whether, if 引导的宾语从句

例句 1). I want to know if/whether he will go to the park with us.

2). Could you tell me if/whether Mr. Li lives here?

小结：if/ whether “是否”，说明对陈述的事物不明确或不清楚。常用在ask, wonder, can(could) you tell me 等后。

注意：只能用whether 不能用if的情况

1）. 在介词后面：

•I’m thinking of whether we should go fishing.

•We are worried about whether it will rain tomorrow.

2）. 在动词不定式前(whether to do sth.)

They asked me whether to go skating.

3）. 当与or not连用，或提出两种选择时:

•I don’t know whether he’s free or not.

•Tell me whether you’d like to go shopping or tidy the room.

4). 宾语从句提前时：

•Whether this is true or not, I can’t say.

3 由连接代词 who,whom,whose,which,what

和连接副词 where,how,why,when引导的宾语从句

例句 1). He asked who could answer the question.

2). He asked whose bike was the best in the class.

3). Can you tell me how I can get to the station?

小结：代词或副词连接主句和从句，并在从句中担任句子成分，具有一定的意义，不可省略。
