1,phrasal verbs短语动词:A phrasal verb is a verb plus a preposition or adverb which creates a meaning different from the original verb.及物或不及物动词与名词,介词,副词等构成的新短语,新短语的意思不同于原动词,牛津词典里面用PHR表示,
例如:I ran into my teacher at the movies last night.run + into = meet.
He ran away when he was 15.run + away = leave home
还有的短语动词如come across,take over,take in,bring up.

例如:he takes the girl in 他带女孩进了房间.这里面in只表示一个方向,可以翻译为里面,take为
谓语,意思没有发生变化.
she took me in completely with her story.他的一番花言巧语完全把我蒙骗了.take及物动词
加介词in构成新短语,take sb.in /take in sb.意思为欺骗,蒙骗.
可以参照一本语法书,章振邦主编"新编英语语法教程” ,里面有详细解释及例句.
