請告訴我
有些人說

等於if
但我不是要那種答案
我是要問
whether
ㄉor not不可略與可略ㄉ情況
所以一定要給我句子
知道ㄇ

Answer 1

A) whether後接名詞子句時：
a)也可用if 取代：
I don't know whether she is right. (較正式)
I don't know if she is right. (口語常用)
b) whether… or not 的位置是很有彈性的：
I wonder whether he needs help. (可以省略)
I wonder whether or not he needs help. (可以在前面)
I wonder whether he needs help or not. (可以在後面)
c) if… or not：
(O)I wonder if he needs help. (可以省略)
(X)I wonder if or not he needs help. (不可以在前面)
(O)I wonder if he needs help or not. (可以在後面)
d) whether在句首：
Whether she loves Tom or not doesn't matter to me.
(不可省略or not，且後接單數動詞)
---------------------------------------------
B) whether後接不定詞：
I don't know whether I should go. (這邊只能用should/can/could)
I don't know whether to go or (to) stay.
---------------------------------------------
C)時態：
a)因為whether是連接詞，所以前後子句詞性要相同。
I can't predict whether she should/can show up.
(現在式can-->現在式should/can)
I asked him whether I could leave.
(過去式asked-->過去式could)
b)whether也可接未來式
I don't know whether he will come or not.

Answer 2

whether...or not 這個句型中，or not 是可以省略的。如：
I don't know whether he can come or not.
同 I don't know whether he can come.

Answer 3

據我所知，or not是可以省略的，
請參考以下：
conj.
1. (引導名詞子句)是否
Ask him whether he can come or not.
問問他是否能來。
I don't know whether you like flowers, sir.
先生,我不知道您是否喜歡花。

2. (與or連用,引導副詞子句)不管是...(或是)
We'll go on with the work, whether we can find the necessary tools or not.
不管我們能否找到所需的工具,我們要把這件工作做下去。
