今天李华碰到了倒霉的事，Michael大力相助，真够朋友的。李华会学到两个常用语：a drag和to start from scratch。
M: Hey, Li Hua. How is your history project going?
L: 你还要问我历史课:的事。唉，我可真倒霉呀！我的电脑坏了，把我写的东西全丢了。可报告明天就要交呢。
M: Your computer crashed? Wow, that's a drag. Is there anything I can do to help?
L: 哎哟，你说什么？什么是drag啊?
M: If something is a "drag," that means it is negative or depressing. The fact that you lost your history project and will probably have to do it again is definitely a drag.
L: 原来a drag就是倒霉的、让人
