宾语从句一.定义:以一个句子作宾语,这个句子就叫宾语从句。
I think he’s a good boy.(宾语从句)(I think是主句)二.通常作三种词的宾语:1.放在动词后作宾语;I think he’s a good boy.2.作介词宾语;Please pay attention to what I say.3.放在某些形容词后作宾语,如:afraid. sure, certain, glad, surprised等。
I’m happy that you can call me back.三.宾语从句三要素:1.陈述语序;2.引导词;3.时态1.陈述语序:主语+谓语+其他。
(陈述语序就是主语在前,谓语在后的语序。
也就是陈述句,它包括肯定句和否定句,它对应的是倒装语序。
倒装语序即把谓语的全部或一部分放在主语前面的语序,如疑问句通常就是倒装语序。
)如:He is a boy. (陈述语序)Is he a boy?(疑问语序又叫倒装语序)I like English.(陈述语序)Do you like English?(疑问语序又叫倒装语序)2.引导词:有三种1).that;2).if/whether;3).疑问词如what/how/where/who...1).以that引导的宾语从句He’s a good boy. I think.(合并为一句)→I think (that) he’s a good boy.总结:作宾语从句的由“原来是陈述句”变来,用that引导,无意义,常可省略(注意:第二个连词that不可省)。
2)..以if/whether引导的宾语从句Is he a good boy? I wonder.(合并为一句)I wonder if/whether he is a good boy.总结:作宾语从句的由“原来是一般疑问句”变来,用if/whether引导,意为“是否”,表达的意思不确定。
原来的疑问语序变为陈述语序,句尾用句号还是问号由主句决定。
if/whether常用在ask, wonder, can/could you tell me 等后。
具有一定的意义,所以不能省略。
3)..以疑问词如what/how/where/who...引导的宾语从句How can I learn English well? I want to know.(合并为一句)I want to know how I can learn English well.总结:作宾语从句的由“原来是特殊疑问句”变来,就用该疑问词引导,原来的疑问语序变为陈述语序(若本来就是陈述语序的,则不变),句尾用句号还是问号由主句决定。
3.时态宾语从句的时态一般受主句的时态制约:1).若主句是现在时态,宾语从句的时态不受限制, 可以根据实际表达的需要来确定。
I have finished my homework. He says. (合并为一句)→He says that he has finished his homework. (原时态不变)2).若主句是过去时态,从句一般要用相应的过去时态。
I'm sorry for being late for class. The girl said. (合并为一句)→The girl said that she was sorry for being late for class.(一般现在时→一般过去时)变化如下:①一般现在时→一般过去时;②现在进行时→过去进行时③现在完成时→过去完成时;④一般过去时→过去完成时;(若有具体的时间状语若in 1990, 时态则不变。
)⑤一般将来时→过去将来时。
⑥过去进行时→不变;⑦过去完成时→不变;⑧过去将来时→不变;3).如果宾语从句的内容是客观事实或真理、自然现象,不管主句是何种时态,从句不受主句限制,都要用一般现在时时态。
“The earth moves around the sun.” the teacher said.(合并为一句)→The teacher said that the earth moves around the sun. Everyone answered there are sixty minutes in an hour.4.否定的前移若主语的谓语动词为think, believe, (expect, guess, imagine, suppose)等, 且主语为第一人称I/We时, 其后的宾语从句若是否定的, 要把否定词转移到主句谓语上,从句谓语用肯定式。
This dress doesn’t fit you well. I think.(合并为一句)→I don’t think this dress fits you well. (我认为这件衣服不适合你穿。
)(注:当主句主语为第一人称时,后面若接附加疑问句,那么附加疑问句的主语、谓语应与从句中的主谓语保持一致。
)如:I don’t believe he is a doctor, is he?I don't think he looks like his father, does he?5. whether和if的用法区别:以下情况只能whether用而不能用if:①在介词之后作宾语②与or not连用③不定式之前④引导主语从句且放在句首时⑤引导表语从句时安徽近年来中考真题(2017·安徽)41.—Do you know ______ Ann goes to workevery day?—Usually by underground.A. whyB. howC. whenD. whether答案B【解析】考查宾语从句中的连接词。
