throw up(短语动词):呕吐;吐出(也可引申为“突然提出/抛出(问题、想法)”,此处以最常见的“呕吐”为主)。
/θroʊ ʌp/
I think I'm going to throw up.
我觉得我要吐了。
After the boat hit rough waves, several passengers threw up, and the crew quickly handed out sick bags.
船遇到大浪后,几位乘客吐了,船员立刻发放了呕吐袋。
throw 原意是“投掷、抛”,up 表示“向上”。合在一起时,形象地表示把胃里的东西“往上抛出来”,因此引申出“呕吐”的口语表达(也常用于非正式语境)。
