台湾籍旅美老师今天交给我们的句子是：
I learned that welders are often smarter than engineers, I learned that knowledge does not equal understanding, and I learned that truth is truth. No matter what I think about it. So be very careful how you interpret things because you're looking at the world with a bias whether you think you are or not.
我了解到了焊接工通常比工程师聪明；我了解到了知道并不等同于理解；我也了解到了无论我的看法是什么，事实就是事实。因此，当你在解读事情的时候要很谨慎，因为无论你自不自知，你其实正带着偏见在看待这个世界。
学习重点：
1.welder 焊工
welder (n.) 焊工
2.engineer 工程师
engineer (n.) 工程师
3.equal 平等的
equal (adj.) 平等的
equality (n.) 平等
equation (n.) 等式
4.bias 偏见
bias (n.) 偏见
discrimination (n.) 辨别
