看影視劇的時候經常聽到有人說：“酒能壯人膽。”不少主人公在踏上冒險之旅前都會喝上幾杯。這樣看來，勇氣可能也不是與生俱來的哦。
Liquid courage is a nickname for alcoholic drinks. It is so named because alcoholic drinks seem to have a fortitude-enhancing effect, making you courageous enough to talk to people you wouldn't otherwise talk to, and not care about things you ordinarily would.
Liquid courage（字面意思為“液體勇氣”）是對酒精飲料的一個戲稱。之所以有這個戲稱是因為酒精飲料似乎有助長勇氣的功效，喝了之後能夠讓人有膽量跟平時不太接近的人搭話，或者變得對平時很在意的事情不那麼關注了。
來看下面這個例子:
Adam got some liquid courage up and tried to ask Lisa out, but he was turned down.
亞當喝了幾杯酒壯膽之後試圖約麗薩出去，可惜被拒絕了。
