Hi everybody, this is Nick, welcome to teaching series “Nick's everyday texts with his American friends”. 大家好，我是Nick. 欢迎来到“Nick和美国朋友的短信日常“. So, in this series, I will teach you guys some authentic phrases and slang by showing and explaining my texts with American people. 那通过讲解我本人，和美国朋友之间发的短信，来达到学习地道英文的效果。短信图片在微博，你也可以关注微博@Nick美语天天说，还有微信公众号“铅笔英语”来获取更多免费内容
今天来一个超级精华好用的短语作为知识点，然后再给大家稍微拓展一下。这个一定要掌握！

1. 你看我之前说什么来着？怎么开启话题？是不是how was your day就是其中一个？

2. knock sth out 这个短语非常的好用。在短信中，我表示的意思是，我刚刚完成，刚刚结束了2门课。相当于I just finished 2 classes. 或者再举一个例子，我在星期五之前要完成这篇论文。I gotta knock out this essay before this Friday.
3. 还有一个很常用的就是knock sb out,意思就是让某人大吃一惊。相当于impress。This movie really knocks me out.这部电影真的让我大吃一惊。
4. 再教一个拓展，叫knock sb up, 意思就是让某人怀孕。但是这个是比较粗俗的说法，相当于中文翻译叫“搞大”，比如说Jack knocked her up but he's not ready to be a dad. jack搞大了她的肚子，但是却没有准备好当爸爸
alright, so this is pretty much it for this time, I'll see you guys next time, bye
