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。

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。 例如：A plane flew above our heads. 一架飞机从我们头上飞过。

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

2. in

介词in表示“在某物的里面”，它通常表示一个物体在另外一个物体的内部、中间或者在某个范围之内。

例如：Your pen is in the pencil case. 你的钢笔在铅笔盒里面。

She is the tallest in her class. 她是她们班最高的。

3. under

介词under表示“在某物的下面”，它通常表示一个物体在另外一个物体的垂直正下面，两者之间没有接触。

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。

例如：He is below the average at school.他的学习成绩在水准以下。

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。

She is standing behind her mother. 她站在她妈妈的后面。

5. next to

next to是由形容词next和介词to构成的介词短语表示“紧挨着、在某物的旁边”的意思。

例如：The table is next to the wall. 桌子紧挨着墙。

6. between

介词between表示某个物体、某人位于两者之间，通常表示一个人、物处于另外两个人、物之间。

例如：Your desk is between the door and the window. 你的课桌位于门和窗户之间。 Lily sits between Mary and Ann. 丽丽坐在玛丽和安中间。

拓展：between和among的区别

between指两者之间, among指三者或三者以上的人或物之间。

答案与解析

Ⅰ. 把下列词组翻译成英语。 1. on the sofa 2. under the desk 3. in your backpack 4. in the drawer

5. in front of the classroom

Ⅱ. 单项选择。

1. D。本句子是考查介词的用法，但是，介词behind，on，in的后面用冠词the和名词、冠词、介词短语，不和to连用，所以本句子是用形容词next和to连用表示“紧挨着、在旁边”的意思。

2. D。本句子用介词on和冠词the，名词wall构成介词短语表示“在墙上”的意思，后面用介词of构成名词所有格，表示所属关系，表示无生命的名词所有格的形式用of，而不用’s形式。

3. C。本句子是考查介词的用法，表示在某物的表面之上用介词on;表示在某物内部用介词in。窗户是在墙的里面所以用介词in;画是贴在墙的表面上，与墙接触，所以用介词on。

4. D。从对话前面的句子I can’t see it.和问句可以判断后面的句子是用介词behind表示“在门的后面”，所以选择D是比较符合对话的上下句子意思和情景。

5. A。句意：“Sally 非常开心，她脸上满脸微笑。”“在„„上”用介词on。

6. A。in bed 表示“卧床(睡觉)”，此时bed前无需加冠词。

7. B。 地图在墙上，故用介词on。

8. A。窗户是嵌在墙里面的，故应该用介词in。

9. D。长在树上的东西用on;外来的东西用in。

10. C。点钟前用介词at。

11. D。句意：“我们可以看见树下有一辆旧自行车。”;“一辆自行车”，故选不定冠词，用因为old以原音开头，所以选an; “在„„底下”用介词“under”。

12. A。可数名词的前面应该加冠词，所以排除B，C项;已经有代词修饰时前面不用再加冠词，故排除D项;因此选A。

13. C。地图在墙的表面用介词on;洞是在墙里面，用介词in。

14. D。句意：“不要在阳光下读书。”;在阳光下不用under用in。
