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。今天是怡茹要问的：开夜车。

Jessica：怡茹, why do you look so tired?

YR: 这几天又复习又考试，累得我眼睛都快睁不开啦! 昨天晚上，我复习了一个通宵啊! I drove a night car!

Jessica: You drove a night car?

YR: 对啊! 我开了一宿夜车! 难道不是这么说的？

Jessica: 哈哈，you should use the phrase "pull an all-nighter." It means you spent the whole night studying or working to meet a deadline.

YR: 哦，整宿学习工作不睡觉，就是 pull an all-nighter. 唉! 都怪我平时没好好复习，期末考试前只能临时抱佛脚!

Jessica: You're not alone, Yiru! A lot of college students pull all-nighters for exams. You can also use the phrase "cram session." It means an intense period of study before a critical exam.

YR: C-r-a-m, cram, 是仓促备考的意思，所以 a cram session 就是考前的突击复习。正说呢，My study group will have a cram session this afternoon for tomorrow's exam. Hopefully we can get everything done before midnight so that I don't have to pull an all-nighter again!

Jessica: Take it easy, Yiru. Isn't your exam tomorrow an open-book test?

YR: Open-book test? 哦，你是说开卷考试吧？没错，这门是开卷，可老师对开卷考试的答案要求更高。我可不想考砸了!

Jessica: You won't bomb it. You're a smart girl!

YR: 你说“bomb"--那不是轰炸的意思么？我猜这就是说没考好，对么？

Jessica: Exactly.

YR: 那要是不及格，挂科了，怎么说呢？

Jessica: Then you can use the verb "flunk", f-l-u-n-k, flunk. It means you fail to pass an exam.

YR: I don't want to flunk my exam, so---I gotta go!

Jessica: Before you go, tell me what you've learned today!

YR: 第一，开夜车，通宵学习工作，叫 pull an all-nighter; 考试前的突击复习叫 cram session;

第二，开卷考试是 open-book test;

第三，考试考砸了用动词 bomb, 不及格则用 flunk!
