If you've ever watched pigs eat, you will certainly have noticed that they have no control over their eating habits. The very sight of food makes them want to fill their bellies, and they don't know when to stop! From that, anyone who eats a lot or can't stop eating makes a pig of himself/herself. This is generally used humorously.
如果你曾經(jīng)看過豬吃東西的話,你一定會(huì)發(fā)現(xiàn)它們毫無吃相可言。只要一看見食物,它們就想把胃塞滿,根本不知道什么時(shí)候該停止。由此,某人吃得很多或者是吃得停不下來就可以說是 makes a pig of himself / herself。這個(gè)詞組一般可以幽默地應(yīng)用:
"I made a pig of myself at Jane's party. I think I sampled everything on the buffet table."
“我在簡的派對(duì)上狼吞虎咽,把自助餐桌上的食物嘗遍了。”
