本义为“在……之间的时间”,由mean(中间的)和while(一段时间)构成,指从某一时间点到另一时间点之间的间隔。引申为“与此同时”,用于对比或补充说明另一事件,强调时间上的同步性。例如,“She was cooking dinner; meanwhile, he was setting the table.”(她在做晚饭,与此同时他在摆桌子。)此外,也可表示“在此期间”,用于叙述中插入另一线索,如“The project will take two years. Meanwhile, we need to secure funding.”(项目将耗时两年,在此期间我们需要确保资金。)
在新闻报道中,常用来连接两条平行的事件线,如“The government announced new policies; meanwhile, protests continued.”(政府宣布新政策,与此同时抗议仍在继续。)在学术写作中,用于对比或补充数据,如“Group A showed improvement; meanwhile, Group B remained stable.”(A组有所改善,而B组保持稳定。)在日常口语中,常简化为“meantime”,如“I'll be busy; meantime, you can relax.”(我会很忙,期间你可以休息。)在文学作品中,用于切换场景或视角,如“Meanwhile, in a distant kingdom...”
语法提示
Meanwhile是副词,通常置于句首或句中,用逗号与主句隔开。它不连接句子,因此不能像连词那样直接连接两个分句,需借助分号或句号。例如,正确用法:“She was tired; meanwhile, he continued working.” 错误用法:“She was tired, meanwhile he continued working.”(需用分号或句号)。易错点:与“while”混淆,while是连词,可引导从句,而meanwhile是副词。
近义辨析
与“meantime”基本同义,但meantime更多用于口语,且常与“in”搭配成“in the meantime”。与“simultaneously”相比,simultaneously强调精确的同时发生,而meanwhile更侧重时间段内的伴随。与“however”相比,however表转折,而meanwhile表时间上的并行。例如,“He was sleeping; simultaneously, the alarm rang.”(他正在睡觉,同时闹钟响了。)强调瞬间同步;“He was sleeping; meanwhile, the clock ticked.”(他正在睡觉,与此同时时钟滴答作响。)强调时间段。
