一只叫 Chaser 的边牧，学会了 1022 个玩具的名字。她的主人是退休心理学教授 John Pilley，花了三年时间一个一个教。这篇从这个让人难以置信的数字讲起，延伸到动物到底有多聪明。文章里的中考常客不少，recognize、respond、command、behavior 在完形和阅读里反复出现。
怎么用这一篇
1先整篇读一遍，一个词都别查。读不懂的地方跳过去，只求知道大概在讲什么。
2第二遍点开带下划线的生词，读完释义再回到句子里，看它在这句话里是怎么用的。
3最后拉到文末的生词表，按「盖住释义」自己回忆一遍，想不起来的点开那一行。
A dog named Chaser could pick the right toy out of a of 1,022. Not by smell. By name. Her owner would say "Get Bamboozle" and she would a stuffed orange horse, every time. She never forgot one. Not a single toy in three years.
Chaser was a border collie who lived in South Carolina with John Pilley, a psychology . After he stopped teaching, Pilley wanted to answer one question. Can a dog truly words, or does it just to tone of voice?
Chaser 是一只边牧，住在南卡罗来纳州，主人叫 John Pilley，退休前是心理学教授。不教课之后，Pilley 想搞清楚一个争了几十年的问题。狗到底能不能真正听懂词，还是只是在对语气作出反应？
He started training Chaser as a puppy. Every day he held up a new toy, its name up to forty times, then hid it among others and gave her a . "Find Sparkle." "Get Santa Claus." He ran after trial, month after month. After three years, Chaser knew 1,022 by name.
Chaser 还是小狗的时候，Pilley 就开始训练她。每天拿出一个新玩具，把名字重复最多四十遍，然后把它藏进其他玩具里，给她下指令。「Find Sparkle.」「Get Santa Claus.」他一轮接一轮地测，一个月接一个月地练。三年之后，Chaser 记住了 1022 个玩具的名字。
What made this was how carefully Pilley tested her. He would toys into groups and mix them in different ways, so Chaser could not remember which pile she had seen before. She had to match a spoken word to the right toy. In hundreds of tests she got it right about ninety-five per cent of the time.
Chaser could also learn a new name after hearing it just once. Pilley would put a toy she had never seen among familiar ones and say an unknown word. Chaser ignored every toy she could already name and brought the new one. Scientists used to think only human children could reason this way.
Chaser's story changed how scientists think about animal minds. Dolphins can follow two-part commands. Crows can solve problems they have never seen before. These animals are more than we used to believe. They in ways that once seemed impossible. The line between human thinking and animal keeps getting thinner.
Next time you call your dog's name and it turns its head, pay attention to that moment. Your pet may understand more than you think. Chaser proved that a dog's mind is far from simple.
