I never knew such a sound sleeper! Once his head touches the pillow, he just lies there as still as death till he's wakened.
我从未见到过这样会睡的人。只要他的脑袋一碰到枕头，他就会死一样地躺在那儿，一动不动的，直到一觉睡醒。
That movie is the sleeper of the year: suddenly everyone has to see it.
那部电影爆出冷门，成了今年的最佳影片。突然间，每一个人都不得不一睹为快
Many sleepers were fixed on a railway.
一条铁路上有许多固定了的枕木。
