英文中的round和around的区别

1、作介词用的around与round通常可以互换,只不过美语常用around,而英语常用round。
【例如】You can see the post office round/around that corner.
绕过那个弯你就可以看到邮局。
2、区别：round可以用作形容词、副词、介词、动词、名词；而around只能用作副词或介词。
【例如】The post office is just round (around) the house (用作介词).
He has round face (用作形容词).
The river rounded the stones(用作动词).
3、在表示"圆形运转,回到原处","环绕","周围"时,英语用round,但美国人用around。
【例如】The earth revolves round(around)the sun.(地球绕太阳运行。)
They sat round(around)the table.(他们围着桌子而坐。)
New things are happening all round(around) us.(新事物在我们周围不断发生。)
There is a small restaurant round(around)the corner.(绕过街角有一家小餐馆。)
4、美国人以及部分英国人也常用around表示"到处","无目的地","附近","左右"等较为模糊的概念
【例如】The news that President Clinton was coming spread rapidly around the campus.(克林顿总统就要到来的消息很快地就在校园里传开啦。)
5、around 还可以表示"不止一处","在许多地方","在不同地方".但在美国英语里,一般只用around
【例如】The students are standing around.(学生们在到处站着。)
They are rushing around in New York.(他们在New York到处奔波。)

这里round是动词，around是介词
