■ unlike

1) 作为介词，后面通常是个名词或代词成分。

• It's unlike any other food I've eaten.它同我所吃过的任何食品都不一样。
• You're unlike me in this respect.你在这方面跟我不一样。
• Unlike me, my brother is very clever.我弟弟同我不一样，他很聪明。

也可以表示违反某人平常给人的印象。

• How unlike you to forget my birthday!连你都忘掉我的生日，真离奇！
• It's unlike you to be so optimistic.你这样乐观，跟你平常可不一样。
• It's unlike him to be late for an appointment.跟平常不一样，他竟然约会迟到了。
• She's been rather unlike herself lately.她最近跟平常很不一样。

2) 但是介词 unlike 后面也可以不是名词成分，而是一个状语成分，合在一起修饰全句。

• Unlike with Katrina, Bush seems aware of possible dangers. (The Sunday Gazette, Schenectady, New York, Oct. 9, 2005)同对待卡特琳娜飓风不一样，布什对于各种可能的危险似乎心中有数。
• Unlike in 2003, when the Archidiocese of Philadelphia publicly ended the careers of four priests, the latest dismissals were not widely known.2003 年时，费城大主教教区公开终止了四名神甫的职务，而与此不同，最近的几次解职，却没有家喻户晓。

3) 作为形容词，unlike 意思是“彼此不相似”，不可以同 unlikely（虽然也是形容词）混淆。Unlikely 后面可以接上 to inf.，而 unlike 则不可。下面例句中的 unlike 如果误认为 unlikely，意义就恰恰相反：

• If the dispositions of the parties are ever so well known to each other, or ever so similar beforehand, it does not advance their felicity in the least. They always continue to grow sufficiently unlike afterwards to have their share of vexation, ... (Jane Austen, Pride and Prejudice, Chapter Six)一对爱人婚前脾气摸得非常透，或者脾气非常相同，这并不能保证他们俩就会幸福。他们总是弄到后来距离越来越远，彼此烦恼，…（如果是 unlikely，就连接后面的 to have their share of vexation，意思变成“日后越来越不会彼此烦恼”）。
