介词和副词用法（PREPOSITION AND ADVERB USES）

Round is an adverb and preposition that has the same meanings as ‘around’. Round is often used with verbs of movement, such as ‘walk’ and ‘drive’, and also in phrasal verbs such as ‘get round’ and ‘hand round’. 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。
