I'd like to reserve a sleeper to Chicago.(我要預訂去芝加哥的臥鋪。)

I've always been a light sleeper.(我睡覺總是容易醒。)

And I am a light sleeper. The least sound awakens me.(我睡覺時很容易驚醒的，一點點聲音都會驚醒我。)

He sacrificed his sleeper to a sick old lady.(他把自己的臥鋪讓給了一個生病的老太太。)

I'd heard from my grandfather that his mother was a poor sleeper.(我從爺爺那兒得知曾祖母睡眠不好。)

Could I change to a sleeper, please?(我可換到臥鋪車廂嗎？)

It has its challenges (one kid is a light sleeper).(這是它們的挑戰(zhàn)(其中一個小家伙有點失眠)。)

The carriage stopped; and the sleeper being roused, was lifted to the ground by his uncle.(馬車停了下來，睡著的人被喚醒了，被他舅舅抱出車外。)

The sleeper effect isn't the great news for advertisers (and advertising agencies) you might imagine.(“睡眠者效應”并不能如你想象中那般成為廣告商們的如意金箍棒（貌似可以的嘛——譯者）。)

This sustained, repeated disturbance is enough to rouse all but the heaviest sleeper.(這種持續(xù)，反復的騷擾足以振奮所有人，除了最嚴重的酣睡者。)
