8. catch some Zs 小睡一下

A：Excuse me. I have to catch some Zs. 抱歉！ 我想小睡一下。

B：I thought you just woke up. Sleepy head. 我以为你才刚睡醒。爱睡虫。

漫画里的人睡觉，不是都画“Z,Z,Z...”来表示吗。这里的“catch some Zs”就是这样来的。“I have to catch some Zs.”也可以说“I have to take a nap.”或“I need to snooze.”

9. take a dump 上大号

A：Would you mind closing the door? I'm trying to take a dump here. 你可不可以把门关起来呢？我正在上大号。

B：Well, learn to lock the door next time. 那么下次学会把门锁起来吧！

“dump”是“丢掉”的意思，“丢”什么不必解释了吧？“我要上厕所”(大小号都一样) 可以说 “I need to use the restroom.” 或简单地说“I need to go.”
