台湾籍旅美老师今天交给我们的句子是：

To drive a hard bargain. This means to negotiate effectively. For example, I can't believe they agreed to it. You sure do drive a hard bargain.
"to drive a hard bargain"意思是有效地进行协商。举例来说，我真不敢相信他们居然同意了。你真的是超会谈判的耶!

学习重点：

1.bargain 便宜货，廉价品
bargain (n.) 便宜货，廉价品
Black Friday (n.) 感恩节之后的星期五

2.negotiate （就…）谈判，（就…）磋商
negotiate (v.) （就…）谈判，（就…）磋商
persuade (v.) 劝服；说服

3.You sure do 当然, 肯定的，毫无疑问的
You sure do (adv.) 当然, 肯定的，毫无疑问的
