jessica在北京学中文，她的中国朋友要是遇到了不知道用美语怎么说的词，就会来请教她。今天是lulu要问的：美容觉。

jessica：hey lulu，i haven't seen you in ages! how's it going?

lulu: 很好很好！就是工作太忙。how are you doing yourself?

jessica: i'm good! speaking of which, some of us are going to karaoke tonight, you've got to come with us!

lulu: 我想去，但我明天得见一个大客户，我们又是公关公司，得保持好形象。所以我今天得早点回家，睡个美容觉。

jessica: beauty sleep? you don't need a beauty sleep, lulu, you are always beautiful!

lulu: 哈！原来美容觉就是 beauty sleep! 真好记。说真的，前一段时间为了搞定这个大客户，我整天加班，睡也睡不好！所以，我得回家补补觉！对了，这个补觉用美语要怎么说呀？

jessica: let me see....you can say you need to catch up on some zs.

lulu: 啊？catch up on some zs?

jessica: 对啊，here we use the capital letter z. it refers to the sound you make when you are asleep. zzzz....you know?

lulu: 哈哈，太形象了！catch up on some zs, 就是补觉的意思！那睡得不踏实，翻来覆去，又要怎么说呢？

jessica: we call that toss and turn. toss is spelled t-o-s-s, toss; and turn, t-u-r-n; toss and turn! 这个词组的意思就是辗转反侧，难以入眠!

lulu: 我最近因为要给这个客户写商业计划，老是睡不好。i've been tossing and turning all night lately.

jessica: oh poor girl! you know what? i think you need to go home and get some shut-eye, we will hang out some other time!

lulu: wait..get some shut-eye? 这难道是休息眼睛的意思吗？

jessica: it's close! actually to get some shut-eye also means to catch up on some sleep, 也是睡觉的意思！

lulu: ok, i will go home now and get a 10-hour sleep!

jessica: sounds good! before you go, tell me what you've learned today!

lulu: 第一，美容觉叫做 beauty sleep;

第二，补觉可以说 catch up on some zs, 或者get some shut-eye;

第三，辗转反侧，叫做 toss and turn.
