150.非洲猫鼬
P1 研究人员观察了野生猫鼬，记录了他们给自己幼崽喂食的一些行为。他们发现，猫鼬给最幼小的崽子喂的猎物65%是活的，给最年长的则90%都是活的。他们猜测，这是因为成年猫鼬向通过这一经历告诉崽子们们怎么去杀猎物。
P2 学者做了实验。第一个实验：播放崽子叫声，幼崽叫声会让成年的带回来更多死了的猎物。第二个实验：他们给崽子喂食。没看懂，煮鸡蛋和一个带刺的啥啥啥，反正结果就是幼崽需要一定的活物，去培养他们进食能力。否则再面对活物就吃不了。
1.Which of the following most accurately states the main idea of the passage? A. Thornton and McAuliffe have argued that experimental results indicate that meerkats teach their pups certain skills through experience. B. Experiments confirm the hypothesis that meerkat pups develop their ability to kill their prey through watching adult meerkats kill their own prey.（没有watching，都是崽子DIY） C. Research conducted by Thornton and McAuliffe reveals that meerkats behave differently toward their young in captivity than they do in the wild.（不是在对比captivity和wild环境因素） D. Two experiments indicate that the reason adult meerkats usually present dead prey to the youngest pups is that these pups are not ready to learn to kill on their own.（不是main idea，main idea是第一段最后一句，他们做了两个实验就是为了证明那句） E. Through their research on meerkats, Thornton and McAuliffe have developed general procedures for testing whether an animal species is capable of teaching.（全文讲猫鼬，这句没一个猫鼬）
2.According to the passage, which of the following is true of adult meerkats? A. They tend to bring more prey to younger pups than to older ones. B. They remove the stingers of the scorpions they present to their young. C. Scorpions are their favored source of food. D. Auditory cues from pups can influence whether they give live or dead prey to their pups.（第一个实验的概括） E. They provide all of the food their pups eat until the pups reach adulthood.
3. The passage most strongly suggests that the foraging ability of meerkat pups A. can, while they are still pups, come to surpass that of the average adult meerkat B. is instinctive but can improve through observation of adult meerkats’ killing their prey C. may not develop effectively if the pups are fed dead rather than live food （第二个实验的启示） D. will develop well only in those pups that make begging calls E. becomes most effective if the pups are always given the same type of food
