从理论上说,两者都可用作名词或副词。表示“其间”、“与此同时”,以下四种表达均可以且可互换:meantime, meanwhile, in the meantime, in the meanwhile。如:
他去伦敦一个星期,在此期间她继续工作。
正:He was in London for a week, and meantime [meanwhile] she went on with the work.
正:He was in London for a week, and in the meantime [in the mean-while] she went on with the work.
但在现代英语中用得较多的是 in the meantime 和 meanwhile。
I will call you Sunday, but in the meantime say nothing. 我星期天给你打电话,但在此期间你什么也不要说。
The train won’t leave for an hour. Meanwhile we can have lunch. 火车还有一个小时才开,其间我们可以吃中饭。
