幫忙點出if和whether whatever和no matter what的用法上最大區別

題目：

幫忙點出if和whether whatever和no matter what的用法上最大區別

解答：

I don't know whether Jack will join in the party or not
有了or not在用whether不會錯
Whatever you do is none of my business
No matter what you say,I won't stop doing that.
whatever可以引導主語從句
No matter what不能引導主語從句,引導壯語從句
