Larry（LL）昨晚因为赶工作而一夜没睡。他正在跟李华（LH）讨论睡眠问题。

LL: Well, Li Hua, I've got to get back to work, and then go home and catch some zzzzs.

LH: 你要回去工作，然后回家，还要抓什么？Catch some zzzs是什么意思呀？Catch是抓住， zzzs是什么啊？

LL: Catching some zzzs means to get some sleep.

LH: 嗯，catching some zzzs就是睡觉！可为什么说catching some zzzs呢？Z不是英语的最后一个字母吗？

LL: You're right. "Z" is the last letter of the alphabet. But many people associate the sound of the letter "Z" ( makes sound zzzzzzzzz) with the sound of snoring.

LH: 噢， z跟打鼾的声音有点像，所以把睡觉说成是： to catch some zzzs。

LL: And to catch some zzzs is to fall asleep, which is really what I need to do now.

LH: 我知道，你已经说了好几遍了， 你现在最需要的就是回去睡一大觉。那你就赶快走呀！

LL: But I still have some things I need to do at work.

LH: 办公室里还有事要做。那你睁不开眼睛怎么办？

LL: There is no need to worry! My desk isn't very comfortable, and the office is pretty loud. I don't think I could catch some zzzs at work, even if I wanted to.

LH: 你怎么那么可怜呢！ 办公室里坐着不舒服，又吵吵闹闹的，想睡觉都睡不着。那你乘车回家的时候在车上睡一回儿吧。

LL: No, I better not do that. If I catch some zzzs on the bus, I might miss my stop.

LH: 那就没办法了。我看你今天只有喝咖啡了。 Larry， 跟你说了半天睡觉的问题，把我都说困了。 Maybe I need to go home and catch some zzzs, too!
