宾语从句
知识提炼
一、概念:在句中起到宾语作用的从句叫做宾语从句。
二、引导词
1. that引导
(1) 当宾语从句为陈述句时,从句是由that 引导的。( that 在口语或非正式文体中可省略)
① I think (that) the girl is beautiful.
② I guess (that) she will become popular.
(2)否定前移
I think (that) the girl is beautiful.
I think (that) the girl isn’t beautiful. ( F )
I don’t think (that)the girl is a teacher. (T )
在think, guess, suppose, believe等动词后面的宾语从句表示否定时,否定前移
2. whether/if引导
(1) 当宾语从句为一般疑问句时,从句是由whether 或if引导。(whether或if 不可省 )
① I’m not sure whether /if she will become popular.
② I don’t know whether/if it’s polite to speak loudly at the table.
(2) whether 或if引导宾语从句的区别
只用whether 情况
① whether…or not
Do you know whether or not it’s impolite to smoke in public?
② 放于句首
I can’t say whether this is true or not.
= Whether this is true or not, I can’t say.
③ 介词之后
I’m interested in whether she likes English.
④ 不定式之前
She asked me whether to start early.
注:if为“如果,假如”引导条件状语从句
He is going to Beijing if it doesn’t rain tomorrow.
3. 特殊疑问词引导
(1) 当宾语从句为特殊疑问句时,从句是由特殊疑问词或词组引导。
特殊疑问词/词组不能省
特殊疑问词:when/where /who/what /how/why ...
常见的特殊疑问词组:How often; How soon; How long ;How many; How much ; What time;What color...
三、语序
Can you tell me? Who are you waiting for?
从句为(陈述语序)
Can you tell me who you are waiting for?
Can you tell me where you bought it?
I don’t know what the brand is.
注意1:(特殊疑问词 )做主语
Can you tell me who broke the window?
Can you tell me who bought the book?
注意2:当从句为 what’ s wrong (with you )/what’s the matter 时, ( 语序)不变
四、时态
1. 主现从任
①I don’t know what the teacher said yesterday.
②I think that you can ask teacher for help.
③I believe that you will pass the exam.
2. 主过从过
My mother asked me what the result was.
I didn’t know whether my answer was correct.
注1:could ①can 的过去式
②委婉语气
在宾语从句中主句有could,一般表示委婉, 符合主现从随
Could you tell me where you____(go/went) yesterday.
注2:真理永现
老师告诉我们地球围绕着太阳转。
My teacher told me that the earth goes around the sun.
