我经常得在上课的前一天晚上备课，为了不打瞌睡，我的很多工作都是距离我们房子一个街区的埃尔姆街餐馆里完成的。

I often had to prepare my lectures late in the evening before the day I delivered them. To stay awake, I did a lot of my work at the Elm Street Diner, about a block away from our house.

每堂课的所有教材会在上课前一天晚上公布，但请确认有无其他东西在上课当天中午以前放上去。

All the materials for each class should be posted the evening before class; but please check for late breaking items posted before noon on the day of class.

I'm going to post PowerPoints for all the lectures, hopefully at least the day before the lecture takes place, so I posted this last night.

我会把课程所有的幻灯片挂到网上,希望至少在上课的前一天完成这件事,因此我昨天晚上把今天的幻灯放上来
