I don't know whether it is true 【or not】.加不加 or not 有什么区别?
请分析,加,和不加,or not 的语法结构,并指出其区别.

whether...or not...固定搭配里“or not"是可省略的.有和没有,无区别.
再问：你是说（1）whether... or not... 【是】固定搭配，照理说必须要加。（2）由于可以省略，所以才不加。如果你说的是这2个意思，请找出参考资料的链接，谢谢！
再答： I don't know weahter it is true. I don't know weather it is true or not. 以上两种说法都对，中文都可翻译为：我不知道这是否是真的。可与whether搭配的是or not，但or not 可有可无。希望这次够清楚了。
