区别:
1. The order that we should send a few people to help the other groups was received
yesterday.

the other groups.

3 3)当doubt作名词用时,同位语从句如果是肯定式,引导词用whether;如果是
否定式,引导词用that

There is no doubt that they will agree with you on this matter.

4)同位语从句有时可以不紧跟在它所要说明的名词后面, 而是被别的词隔
开,这种从句叫分隔式同位语从句。
The idea occurred to me that he was not a child any more.
The whole truth came out at last that it was a wolf in sheep's clothing.
五、wh-ever引导名词性从句
Whatever he likes will be given to him.

She will give whoever needs help a warm support.
注:no matter +wh- 不能引导名词性从句


六、whether和if的区别
1)只用whether不用if的情况
引导位于句首的主语从句、表语从句、同位语从句时。
从句作discuss或介词的宾语时
紧跟or not时
在强调任意选择时,用whether?or
句子中有if引导的条件句,如再有表示“是否”的宾语从句,用whether不用if
2)如果宾语从句为否定句时,则只用if不用whether
用whether或if填空
1. I want to know you can come back.
2. It hasn’t been decided these foreign guests will visit our college.
