口语：你突击复习过吗？
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。今天怡茹要问的是跟考试相关的'表达。
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: Youre 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 tomorrows exam. Hopefully we can get everything done before midnight so that I dont have to pull an all-nighter again!
Jessica: Take it easy, Yiru. Isnt your exam tomorrow an open-book test?
