I got less than I wanted when I sold my car but I made a good profit on the caravan-what you lose on the swings, you gain on the roundabouts. 我的汽車(chē)沒(méi)能賣(mài)出好價(jià)，但我的有大篷的卡車(chē)卻賣(mài)出了價(jià)錢(qián)——真是失之東隅，收之桑愉。
The sea is gaining on the land. 海水逐漸侵蝕陸地。
What you gain on the swings you'll probably lose on the roundabouts. 有所得也可能有所失。
The sea was gradually gaining on the buildings, which at length almost entirely disappeared. 大海不斷地侵蝕著(zhù)這些建筑物，最后它們幾乎完全不見(jiàn)了。
