Unit——常用示方位的介词和短语

概念引入本单元学习介词＋定冠词the＋名词构成介词短语的用法，介词后面可以跟名词和代词做宾语，构成介词短语。

今天我们主要学习一下用来表示方位的介词和介词短语。

1. on介词on表示“在某物之上”的意思，它通常表示一个物体在另一个物体之表面上面。

两者之间有接触。

例如：Your book is on the desk. 你的书在课桌上面。

There is a ball on the floor. 地板上有个球。

拓展：above 和 over的区别on指的有接触面的上面，但是over和above都是没有接触面的上面。

over“在……正上方”，与under相对。

例如：There is a bridge over the river. 河上有一座桥。

The picture is hanging over the blackboard. 那张图挂在黑板的正上方。

above只表示“在……上方或位置高出……”，不一定是正上方，与below相对。

The Turners live above us. 特纳一家人住在我们的上面。

例如：My bike is under the tree. 我的自行车在树的下面。

The shoes are under the chair. 鞋在椅子的下面。

拓展：under和below 的区别under表示“在……之下”，通常表示位置处于正下方，与介词over“在……上方”相对应。

例如：There is a book under the table. 桌子下面有一本书。

A cat is sitting under the table.一只猫在桌子下面。

below表示“在……之下”，“在……的下游”，与介词above相对应，常指在某物体之下，但不一定在该物的正下方。

He looked down at the hall below. 他瞧了瞧下面的大厅。

4. behind介词behind表示“在某物的后面”，它通常表示一个物体在另外一个物体的后面。

例如：Your brother is behind the tree. 你的弟弟在树的后面。
