宾语：Let us know whether / if you can finish the article before Friday.请让我们知道你是否能在星期五以前把文章写完。

I want to know whether it’s good news or not . 我想知道是否是好消息。
3 、在介词后，只能用whether。
His father is worried about whether he lose his work . 他的父亲担心是否会失去工作。
4、宾语从句放在句首表示强调时，只能用whether 。
Whether this is true or not, I really don’t know. 这是否真的，我真的不知道。
3、（例11 Whether they can finish the work on time is still a problem . 他们是否能准时完成这项工作还是个问题。
－－此例为主语从句，有误，感谢指出）5、用if会引起歧义时，只用whether。
如：Could you tell me if you know the answer ? 这句话有两种意思：“你能告诉我是否知道答案吗？”或“如果你知道答案，请告诉我，好吗？”。
如用whether可避免歧义.九, whoever 和whatever 引导的名词性从句whoever引导主，宾从句=anyone who---whatever引导主，宾从句=anything that---Whatever is left over may be put into the refrigerator, where it will keep for two or three weeks.(2011安徽卷28)=Anything that is left over may be put into the refrigerator, where it will keep for two or three weeks.Whoever walks around in such a heavy rain will catch a cold.任何在这样的大雨中行走得人都会患感冒。
