看美剧学英语高频短语：Lighten up

Fannie

Lighten up: to become less gloomy, and more cheerful; to become more relaxed and less serious（振作起来；别那么紧张；放轻松点）. We use this expression to tell somebody to take a more positive attitude. Usually this is when you are annoyed by somebody being negative.

中文释义:"lighten up"一般用来告诉别人不要沮丧，振作起来，在一定程度上lighten up=cheer up；也可以用来告诉别人高兴点，放松点，别那么严肃（都用于鼓励安慰他人）。例句："Lighten up!We can go to the movies another day."（别不开心啦！我们可以改天再去看电影。）在这里引申一个易混淆短语“light up”，它和“lighten up”的意思相差甚远，light本身是点亮、点火的意思，light up主要是用于表示点灯或者是房屋亮起来了，例句：A candle is not enough to light up the whole room.（一根蜡烛不足以照亮整个房间。）
