4.Vital 至关重要的
5.Human progress 人类进步
6.Let slip 错过;放开

2. we cannot afford to let slip(something的定语从句)
参考译文：区分事实和观点和对我们所谓的知识保持怀疑的能力对于人类进步至关重要，这种能力也是我们无法忽视的东西。
思考题：
Knowledge about fact and opinion is something that we cannot ignore.
关于事实和观点的知识是我们不能忽略的东西。
这个说法就是一种偷换;
不是关于事实和观点的知识，而是如何区分观点和事实的能力，以及去质疑我们称之为知识的能力，是我们不能忽视的。
(至于昨天F和T的位置我是提醒过的，结尾又彩蛋，你自己不注意我能说什么。但是希望同学们仔细点，每年都有同学填错答题卡的。我们一定要尽全力，不犯低级错误!)
