while,but和whereas三个词怎么区别?
but是这三个连词最普通的一个,它可以连接两个并列成分或两个并列分句,意为“但是,然而”.如：Mary likes classical music but her husband likes rock music. 但在使用时要注意：but不能与though/although连用.其次but词性不一样意思也不同,比如作介词,常与nothing nobody who all等连用,意为“除……之外”.如： We had nothing to do but wait. 而连词while在对比情况下使用意思是“而然而”.但和主句连接时要用逗号和主句隔开,来看一个成语感受体会一下 Honey is sweet while the bee stings. 蜂蜜很甜但蜜蜂有刺蜇人.从属连词whereas也可以引出表示对比、对立或直接相反的状语从句,是三个连词中最正式用法,语气强并且书卷气较重,通常多位于居中,也可置于句首；和while一样通常多用逗号隔开如His parents were rich whereas mine had to struggle.
