whether和if的用法分析
whether和if都可以引导宾语从句,表示“是否”,在口语或间接引语中两者可以互换使用.如:

I wonder if / whether I can get some advice from you.

Ask him whether / if he can come.

但在有些情况下,whether和if的用法有一定区别.

1. whether引导的从句常可以与连词or或or not直接连用,而if一般不能.如:

正: Let me know whether you can come or not.
误: Let me know if you can come or not.

2. 当宾语从句提到句首时,只能用whether引导,而不能用if.如:

正: Whether it is true or not, I can’t tell.
误: If it is true or not, I can’t tell.

3. whether可以引导带to的不定式,if则不能.如:

正: I don’t know whether to accept or refuse.
误: I don’t know if to accept or refuse.

4. whether及其引导的成分可放于介词之后,作介词的宾语,但if不能.如:

正: I worry about whether I hurt her feelings.
误: I worry about if I hurt her feelings.

5. whether可以引导从句,作主语、表语或同位语,而if不能.如:

正: It was uncertain whether he would come.
误: It was uncertain if he would come.

正: His first question was whether Tom had arrived yet.
误: His first question was if Tom had arrived yet.

正: We must consider the question whether we will take these measures.
误: We must consider the question if we will take these measures

whether or not 呢,是单独用作状语,具体意思是和上下文关联着的,不管怎么样,后边跟的句子是结果,已经发生的事情
whether……or not是另一个用法,放在……的句子是一个条件而已,一起作为一个状语,后边的句子才会是表达的主干
你的例子:1不管怎么样,我已经完成了我的工作
2 做完了我的工作或者没做完,(你都无权过问)【后边是给你加的一句话,便于你理解二者的区别】
