我一直想买幅油画，挂在客厅墙上，可是这里卖的画儿都特别贵。星期天，我开车路过一个小区，几家人正在一起卖旧货。我一眼就看中了一幅特别好看的油画，卖主让我开价，我说50美元，本以为根本没戏，谁知他却一口答应。在英语里，我们可以说：for a song.
大家知道，song是歌曲的意思。For a song这个习惯用语的意思就是说买了便宜货。我最近才花了50美元就买了一幅很好的油画，就可以说，You picked it up for a song.
例句-1：The recent downturn in the U.S. housing market represents good news for buyers. In states like Florida, you can find expensive properties going for a song. But you had better take advantage before prices start going up.
例句-2：My cousin is thrilled. He just accepted a marketing job overseas. Since he won't be needing his sports car, he's willing to let me have it for a song. I'll be paying so little for it, in fact, it's almost like he's giving it away.
