whether or的一些问题
whether you work hard or not.我想问为什么后面用not不用dont ?whether是连词的呀~~后面是两个句子吧?

whether you work hard or not=whether you work hard or you don't work hard.
但这样说的话,明显与前面重复了,所以一般说whether you work hard or not或者whether or not you work hard
请及时采纳,不懂继续问所以我不知道是哪条语法说要用not替代?not 经常用来替代整个否定句,以避免重复。如:You must work hard. If not(=If you don't work hard), you 'll fail in the exam.再如:A; Will he go there with us?B: I am afraid not. (= I'm afraid he will not go there with us.)
