中国科举是古代很大的考试。你如果考过第一级，你就是一个举人。然后，你要考解元，这是三元中第一元。明年，二月份，你就要考会元，这是三元中的第二元。这考试真的是一个很苦的考试，没有什么教师给你考，就是一个监狱。考生的屋子长五尺，宽四尺，高八尺，进去只能带三根蜡烛，笔，墨，和一个考卷。一进去，外面就上锁关门。晚上想睡觉就要我在地上睡。考完这个考试，就要考第三元, 这个考试每三年只有一场，如果考过就能当官。

朱元璋拟定了一个几乎完美的计划。朱元璋的大军分了三路，其中徐达是中路，李文忠是右路，和冯胜为西路。在出征之前，朱元璋让将军们自己挑先锋。徐达挑了蓝玉，冯胜挑了傅友德。这个人是个真正的传奇人物，从来没有打过败仗。蓝玉和傅友德一起把王保保打得落花流水，他被逼迫撤退。王保保知道他军队的实力不够，打不过明军，所以只能用伏军。王保保等着明军追上来。果然，明军追了王保保，追到了一个埋伏里。元军的埋伏没成功，明军把他们追回到了蒙古。傅友德又征服了好几个城池。

Many websites are playing even more and more on people's natural feelings. These strategies are employed frequently on websites like Amazon. On Amazon, signing out is hard. There is no obvious 'Sign out' button, and to sign out you have to hover over your name, and then scroll to the bottom. There is a small button which says "Not (blank)? Sign out". It makes you feel weird because to sign out you have to say that you are not you. There's also scarcity inflation. Some websites say that there is only one left, when in actuality there are a lot left. This plays on people's natural biases, making them want to buy the product. Also, websites are designed so that it is easy to sign up, and then hard to opt out. Or so that the expensive things are highlighted, while the other things are very hard to see. Or that there are tiny checkboxes that you can barely see that will spam you with e-mail if they are left checked. These websites do experience better res

Fentanyl is a new drug that is insanely powerful. At 50 times the power of heroin, 2 mg, or six grains of salt, could be lethal. And this drug is much cheaper, too. It is being produced in Mexico, in illegal labs. It is being produced in China, where it can be ordered in the mail. It does not require large swaths of poppy fields to produce. It can be produced by simple chemistry. Joseph was a high schooler. He had a job, and earned $12.75 an hour at a nursing home. The year after he graduated from high school, a friend gave him some Percocet pills. When he took them, he instantly felt high. He said that he wanted to feel like that for the rest of his life. His habit quickly escalated to 10 or 20 pills a day. Then he got into fentanyl. He became insanely high and wandered around like a drunkard. Crashing into doors. Doing stupid things. He got put in jail, then right afterwards, he got high again. Modern technology has made more and more drugs that are even worse than the last. Each

王保保的军队实在太累了，他们一看到明军退后了，就睡着了。他们知道这次安静并不正常，但他们实在太累了。徐达趁机进攻了。王保保整个的军队一下子就被消灭了。王保保逃掉了，但他的军队全都被抓住了。王保保的十万大军一晚上就被毁掉了。王保保逃到了河边，没有渡河的船，所以他拿了一块儿木头，让老婆，孩子，和自己抓住，然后从黄河一边到另外一边。他跑回到了蒙古，然后开始痛哭。

徐达率领明军骑兵，到达了王保保的军的地方，但因为兵力不够强，徐达没有发动进攻。徐达决定不打也不撤。常遇春决定应该偷袭敌营。这个计划成功了，王保保被打得落花流水。此时，中国北方的地区落进了明军的手里。王保保只能逃回到太原。但王保保也有计划。他多在太原也是有原因的。他现在就要等一个鱼上钩。过了一些时候，他得到了一个机会。他拿了十余万军，让一万军进兰州，另外一些军围在兰州外面，藏起来。他知道兰州对明军太重要了，肯定会有人来救援。果然，于光来救援了，很快就被杀了。王保保知道还会有人来，所以他就待在兰州，等着。果然，又有了一个鱼上钩，但这次是个鳄鱼。朱元璋亲自率领大军，分五路来打王保保。
