1．Drink like a fish 豪饮；牛饮
鱼在水中游时总是张着嘴，以便让水通过鱼鳃以获得氧气。而人们常常误以为鱼是在不断喝水，便用drink like a fish一语来比喻“过量饮酒；豪饮；牛饮”。
He drank like a fish because he had worked for three hours in such a summer day. 他不停地喝水，因为他已经在这样一个大热天里干了3个小时活了。
2．Drop in the bucket/ocean 沧海一粟
语出《圣经·旧约·以赛亚书》第40章第12节：“看哪，万民都像水桶中的一滴，又如天平上的微尘……”（Behold, the nations are as a drop of the bucket）其喻义为“沧海一粟”。后来该语又产生了一个变体drop in the ocean。
If your father lends us some money it will be very helpful but it will really only be a drop in the ocean when we have to pay all our debts. 你父亲如果借些钱给我们当然很好，但我们要还清所有的债务，这点钱只不过是杯水车薪。
3. Eat the fruit of one's own doings 自食其果
源于《圣经·旧约·以赛亚书》第3章第10节。此节中有如下诗句：“你们要对正义的人说：他必享福乐，因为要吃自己行为所结的果子。”（Say to the righteous that it shall be well with them, for they shall eat the fruit of their doings.）现在，人们就用eat the fruit of one's own doings来比喻“自食其果；因果报应”，常含有贬义。
You'd better stop cheating, or you will surely eat the fruit of your own doings one day. 别再欺骗别人了，否则你总有一天会自食其果的。
4. Every dog has his day 人人都有得意之日
源于公元前5世纪古希腊诗人品达罗斯（Pindaros）的《哀悼歌》（Odes of Condolence）中的诗句：人人终有得意时，晨时欢笑夜时悲。（Thus every dog at last will have his day—He who this morning smiled, at night may sorrow.）在西方人看来，狗是人类最好的朋友，人们常用dog一词代指“人”。因而实际上every dog has his day用来比喻“人人皆有出头日；时来运转；风水轮流转”等义。
Mary will be able to go to dance like her sister when she grows up. Every dog has his day. 玛丽长大后也能像她姐姐一样参加舞会，人人都有出头之日。
