---in Objective Clause
人教版B3U3
The Million Pound Bank Note
当宾语从句是一般疑问句时，由连词if 或whether引导（口语中常用if），因为if/whether翻译成：“是否”，具有一定的意义，所以不能省略.
Did they have a sports meeting
Will they go for camping？
I want to know if/whether…
Lily wanted to know if /whether her grandma
liked the handbag .
Let’s see if /whether we can find out some
information about that city .
She asked if /whether she could borrow
these books .
常放在动词know 、see 、ask 、say
和find out等后面
if和whether的区别
1.if和whether都可以引导宾语从句。
2.只能用whether的情况
a.当whether后紧跟or not时,不用if
e.g.I don’t know whether or not I will stay.
if 和whether的使用区别
I worry about whether I hurt her feelings.
I am not interested in whether you will come .
b. 介词后面的宾语从句不能用if.
He doesn’t know whether to stay or not.
She doesn’t know whether to get married now or to wait.
c.后接动词不定式 (whether to do sth.)
Look at the sentences and find out the rules.
和or not 连用
放在介词之后
后接动词不定式
I don’t know whether or not he will come .
He is thinking about whether he has shut the door.
I am not sure whether to accept his invitation.
只用whether 不用if
