Dogs are also great at trickin9．During play，they have the ability to trick humans and other dogs in order to get treats．“And they are nearly as successful in tricking humans as humans are m tricking dogs，”says Coren．

参考答案B

解析:　　参考译文：根据一项新的研究，狗和两岁孩子的智力差不多。狗给它的主人带来很多快乐，甚至有助于人体健康。大多数两岁的孩子会让我们的生活非常忙碌，这是让我们长寿和开心的很重要的一部分。英国哥伦比亚大学斯坦利·科伦博士说，我们的狗比我们想的要聪明。
科伦博士回顾了很多研究，发现狗和2到2．5岁的孩子智力差不多。科伦博士说，不要总想着一个字的指令，最聪明的狗可以记住高达250个字。大多数的狗可以听懂将近165个字。“狗狗学习语言能力的上限，部分基于对一只叫里科的博得牧羊犬的研究得来，它可以听懂200个字，并可以‘快速追踪学习’，这点科学家认为只有人和学习语言的猿具有这种能力。”
狗狗也很擅长恶作剧。在游戏的时候，他们有能力逗人和其他狗玩以得到奖励。科伦博士说，“他们几乎可以成功的像人逗狗玩一样逗人玩”。狗狗可以数到4或5，这就可以解释他们玩具丢了的时候他们是怎么知道的了。科伦博士解释道：“他们令人震惊的灵光一现和创造力在告诉我们，狗狗们虽然不是爱因斯坦，但他们的智力绝对比我们想象中更接近人类。”
动物们可以做很多让我们开心、健康，以及保护我们不受伤害的事。狗英雄的故事在网上简单一搜比比皆是。宠物教会我们责任感，让我们不孤独，还能帮助残疾人康复。狗狗比我们想象的要聪明，和两岁的孩子一样聪明。
【精析】细节题。题干意为“根据文章，狗狗怎么给人类带来欢乐和健康的?”从文章第一段第二句“Most two year olds keep US busy in life-an important part of living a long and happy life．”可以得知，两岁小孩让人们忙碌，这是令人长寿和快乐的方式，而文中一直在说狗和两岁小孩智力差不多，故选B。
