注意:只能用if 不能用 whether的情况
1.引导条件状语从句(If :”如果”) If he runs fast, he’ll get there on time. I’ll go to see you if I have time. 2.引导否定的宾语从句 Tell me if it is not going to rain, please.

(复合句)
2. I know who he is .
主语 谓语 连词 从句主语 从句谓语
主句
宾语从句
什么是宾语?
I know him. Do you have the time? I think (that) she is beautiful. Why don’t you pay attention to me?
5. I don’t know _w_h_e_th_e_r_ to go.
由连接代词 Who,whom,whose,which,what 引导的宾语从句
宾语,位于谓语动词或者介词后。
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。
eg. We know Mr Green teaches English.
She asked if these answers were right.
二、宾语从句三要素
引导词(连接词) 语情况 2
4. 在介词或dicuss后面: I’m thinking of whether we should go fishing. We discussed whether we should close the shop.
5. 与动词不定式连用(whether to do sth.) : They asked me whether to go skating.
条件状语从句: 主将从现
时 态 宾语从句: 根据需要用相应时态
if whether用法巧记 两个“是否”并不难,一般情况可代换。 下列情况用whether, 主表不定式or (not)。 作为讨论介词宾, 此时 if 不可跟。 还有一点也得编, whether从句可提前。 引导条件表“如果”,再也不可用 whether。 宾语从句若否定, whether一词不可用。
3.当与or not连用,或 or 提出两种选择时: I don’t know whether he’s free or not. Mary asked whether I was doing my homework or not. Tell me whether you’d like to go shopping or tidy the room.
注意:只能用 whether不能用 if 的情况 1
1. 在引导主语从句、表语从句时如: ⑴Whether it is true remains a question. ⑵The question is whether it is true.
2. 用在动词不定式之前时用whether不用if。 I don’t know whether to go there at once.
