大家好，我是小夏，我来为大家解答以上问题。in the meanwhile，meanwhile很多人还不知道，现在让我们一起来看看吧！
1、没区别
2、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：
3、他去伦敦一个星期，在此期间她继续工作。
4、正：He was in London for a week, and meantime [meanwhile] she went on with the work.
5、正：He was in London for a week, and in the meantime [in the mean-while] she went on with the work.
6、但在现代英语中用得较多的是 in the meantime 和 meanwhile。
7、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。
8、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。
本文到此讲解完毕了，希望对大家有帮助。
