PREPOSITION AND ADVERB USES 介词和副词用法
-
Round is an adverb and preposition that has the same meanings as ‘around’.

Round is commoner in British English than American English, and it is slightly more informal.
round用作副词和介词时与around同义。round常与表示动作的动词连用，如walk和drive，同时也可以用在get round和hand round之类的动词词组中。round在英国英语中比在美国英语中更常用，且略显不正式。
