英语翻译
Be careful what you say around your dog.It might understand more than you think.A border collie named Rico recognizes the names of about 200 objects,say researchers in Germany.The dog also appears to be able to learn new words as easily as a 3-year-old child.Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).In one experiment,the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects.Then the owner told the dog to go and fetch one of the items and bring it back.In four tests,Rico got 37 out of 40 commands right.As the dog couldn't see anyone to get clues,the scientists believe Rico must understand the meanings of certain words.In another experiment,the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew.The owner then told Rico to fetch the object,using a word the dog had never heard before.The correct object was chosen in seven out of l0 tests,suggesting that the dog had worked out the answer by process of elimination(排除法).A month later,Rico remembered half of the new names,which is even more impressive.Rico is thought to be smarter than the average dog.For one thing,Rico is a border collie,a breed (品种)known for its mental abilities.In addition,the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.It's hard to know if all dogs understand at least some of the words we say.Even if they do,they can't talk back.Still,it wouldn't hurt to sweet-talk your dog every now and then.You might just get a big,wet kiss in retur

在狗面前说话要小心,它的理解能力可能超乎的你想象.德国的研究人员说,一只名为Rico的边境牧羊犬能认识200个东西的名称.这只狗表现出可以象一个3岁的孩子一样轻松学习新单词的能力.它学习单词的能力超过鹦鹉和黑猩猩.在一项实验中,研究人员把200个Rico认识的东西分成20组,每组10个.研究人员告诉狗去找出其中一个,并把它带回.在4次测试中,Rico得到40次命令,做对了37次.当狗无法看到人得到线索的情况下,科学家认为,Rico必须了解某些词的含义.在另一项实验中,科学家把一个Rico从未见过的玩具和它已经知道名字的7个玩具放在同一个房间内.然后研究人员用一个Rico从来没有听说过的单词,命令它取回这个玩具.10次测试,Rico做对7次,表明Rico是用排除法选择正确答案.一个月后,令人惊奇的是Rico这些新玩具的一半.Rico被认为是比一般的狗聪明.需要说明的是,Rico是一只以智力闻名的边境牧羊犬.此外,9岁的Rico在9个月时就训练按玩具的名字取玩具.很难知道所有的狗是否理解我们说的一些话.即使它们知道,也不会与我们顶嘴.不过,这并不妨碍经常对你的狗说些甜言蜜语的话.你可能会因此得到你的狗一个大大的热吻.
