Good morning!
昨天的文章又发完了，抱歉！我秋季在美国，所以要记得下午把准备好的文章发出去。我弄了个闹钟，但是响的时候正在开会，后来没想起来。
一旦没有发，就有好多人发消息怕我出事了。一方面特别不好意思，耽误了大家的时间，另一方面特别感动，有这么多人跟我一起练习。谢谢！
...
几乎所有的人认为新话筒的效果很好，那就买值了！
昨天的是在车上录的，今天的回到房间里录了，好像回音大一些。
不过，整体效果应该还是比之前用iPad自带的麦克风好不少。请继续给反馈，我慢慢调整设置与环境。

今天的练习内容是关于经济学得诺贝尔奖。等等，别走！还是挺有意思的，也没有那么难。
文章来自The Economist，朗读内容是文章的开头，作者用了开Lemonade stand的例子介绍经济合同的作用。
Lemonade stand是个非常典型的“第一次生意”，在美国小孩经常会做自制的柠檬汁，在小姐边上摆摊卖。因此，它也成了介绍商业理念的典型例子。
Have fun!
John
朗读内容
The Economist: Oliver Hart and Bengt Holmstrom win the Nobel prize for economic sciences
SUPPOSE that you and I are interested in opening a lemonade stand together. We agree that I will bring the materials we need (cups, stand and so forth) while you will make the lemonade. I’ll do the pouring while you mind the cashbox and at the end we will split the proceeds fairly. A doubt niggles, though. I am worried you might, at the end, try to hog the contents of the cashbox. We therefore decide to draw up a contract (common practice in the lemonade-stand industry) dictating that the returns to our operation must be split evenly. But then you start to worry: much of the success of our stand will depend on the quality of the lemonade, over which I have no control. What if I decide to slack off and piggyback on your lemonade-brewing genius, knowing that after you pour your sweat into the lemonade (not literally), the split is still an even 50-50? We therefore set to haggling over language in the contract setting out precisely how each of us should do our respective jobs.
Contracts play a critical role in the operation of the modern economy. They set out who is allowed to do what with the land they own, the people they employ and the songs they store on their smartphones. They underpin nearly all of the banking and insurance sectors. Individuals are self-interested, but to take advantage of economic opportunity people must often work together and find ways to align their interests (or minimise conflicts of interest). That’s where contracts come in. This morning, The Swedish Riksbank awarded this year’s Nobel prize for economic sciences to Oliver Hart, a British economist at Harvard University, and Bengt Holmstrom, a Finnish economist at MIT, for their work improving our understanding of how and why contracts work, and when they can be made to work better.
