宾语从句复习要点 一、连接词 1. that引导宾语从句时,只起连接作用 ●I know(that) he is a Canadian athlete. 2. whether或if引导宾语从句时,意为“是否”,。如: ●I don’t know whether/ if my parents agree with me. 注意:与or not直接连用时只能用whether不可用if。如: ●He didn’t say whether or not he would be staying here. 下列情况下只能用whether： ①在具有选择意义，有or或or not时，与or not连用时，用whether(if…or not也可以使用) Let me know whether /if he will come or not.(=Let me know whether or not he will come)让我知道他是否能来。 　　I dont know whether /if he does any washing or not.(=I dont know whether or not he does any washing.)我不知道他洗不洗衣服。 I wonder whether we stay or whether wego.我不知道我们是去还是留。 　　②在介词之后用whether 　　Im interested in whether he likes English.我关心的是他是否喜欢英语。 　　Were thinking about whether we can finish the work on time.我们正在考虑是否能按时完成这项工作。 I worry about whether I hurt her feelings.我担心是否伤了她的感情。 ③在不定式前用whether 　　He hasnt decided whether to visit the old man.他尚未决定是否拜访那位老人。 　　I dont know whether to go.我不知去否。 He hasnt decided whether to go by bus or by train.他还未决定是乘公共汽车去还是坐火车去。 ④whether置于句首时，不能换用if Whether this is true or not，I cant say.这是否真的我说不上来。 ⑤引导主语从句和表语从句时宜用whether 　　Whether she will come or not is still a question.她是否能来还是个问题。 The question is whether we can catch the bus.问题是我们能否赶上公共汽车。 ⑥若用if会引起歧义时，则用whether Please let me know if you like the book.可理解为： 　　a.Please let me know whether you like the book.请告诉我你是否喜欢这本书。 　　b.If you like the book，please let me know.你如果喜欢这本书，请告诉我。 简化宾语从句的方法： 方法一：当主句谓语动词是hope， decide， wish， choose， agree， promise等，且宾语从句的主语与主句主语一致时，宾语从句可简化为不定式 Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon.
