介词

学习介词的最好方法是要弄清楚介词与介词之间位置上的关系，请参考下图：

I．分类：

1．常用简单介词：
about, across, against, among, after, at, behind, besides, beyond, by, concerning, beneath, between, despite, except, during, down, for, from, past, than, under, until 等。

3．短语介词：

II．介词与“……的”之关系：

在英语学习中，一遇到“……的”，大家就会立刻想到’s 所有格或者of。实际上，在很多情况下，“……的”必须借助于介词才能准确表达。
