介詞是英語中最活躍的詞類之一。許多介詞搭配力特別強,和其他詞連用可以表示各種不同的意思。大部分的習用語,都是由介詞和其他詞構成的。翻開一頁書,我們可以找到大量介詞。因此掌握好介詞是學好英語的關鍵之一。英語中最常用的介詞有下面這些,可分為三類:
1.簡單介詞:
about, across, after, against, among, around, at, before, behind, below, beside, besides, between, beyond, but, by, despite, down, during, except, for, from, in, like, of, off, on, over, near, past, round, since, though, till, to, forward (s), under, until, up, with, per, via.
2.合成介詞:
in side, into, onto, out of, throughout, outside, upon, within, without.
3.成語介詞:
according to,along with,apart from,as for,as to,because of,by mean of,in front of,in spite of,instead of,in accordance with,on account of,on behalf of,due to,owing to,together with,up to,with regard to,next to,prior to等。
其中最重要的是簡單介詞。成語介詞和介詞的成語的區(qū)分并不很明顯。大體上說來,意思上和作用上相當于一個介詞的,就可稱為成語介詞,如:in front of接近before,in addition to接近besides,in spite of 接近 despite.
