We know people can be nice, but what about animals?

Scientists say that some animals are capable（有能力的）of being nice. Animals that live in groups-like foxes, chimpanzees（大猩猩）, and elephants-follow rules. They have to follow rules to get along and to survive（生存）. However, animals can act nicely, even when they don't have to. Here are some surprising stories about animal behavior.

Most people usually walk away when someone is unkind to them. Marc Bekoff, a researcher at the University of Colorado, saw a female（母的）red fox do just that. The female fox was unhappy because a male（公的）fox played roughly（粗鲁地）with her. When she walked away, the male fox showed her that he wanted to play nicely. He lowered his head and rolled on his back. The female fox gave him another chance, and this time, he played more gently.

Geza Teleki is a scientist who studies chimpanzees in Tanzania. One day, Teleki hiked far away from his campsite. He didn't have any food. Teleki wanted some fruit from a tree, but the tree was too tall. A young chimpanzee watched him curiously as he tried to get something to eat. The chimpanzee climbed the tree, picked the fruit, and gave it to him!

An elephant in Kenya hurt his trunk（象鼻子）. He needed help because he couldn't put food into his mouth. Researcher Kayhan Ostovar watched silently. He saw the hurt elephant show his sore trunk to a healthy elephant. The healthy elephant didn't need any more information. He took a bush and put it carefully into his new friend's mouth.

Hippos（河马）and crocodiles are usually good friends. They hang out together in rivers. But Karen Paolillo, a wildlife expert in Zimbabwe, saw something surprising. One day, a crocodile tried to eat a monkey that was next to a river. A hippo ran quickly to the crocodile and chased it away. Why did the hippo attack（攻击）the crocodile? Paolillo says hippos sometimes protect other animals from crocodiles.

【回答】

【文章大意】本篇文章难度适中，主要通过几个令人吃惊的故事表明有时候一些动物也会表现得很好。例如赤狐、猩猩、大象以及河马。

41. B主旨大意题。根据However, animals can act nicely, even when they don't have to. Here are some surprising stories about animal behavior以及全文可知，动物有时候会表现的很好，甚至有时候他们没有必要这么做，后文讲述了几个故事，说明有些动物对其他动物表现得很好，故选B。

42.C词义猜测题。根据Most people usually walk away when someone is unkind to them. Marc Bekoff, a researcher at the University of Colorado, saw a female（母的）red fox do just that可知，当某人对一些人不友好时，他们会生气地走开，母的赤狐也像那样做，指的就是赤狐也会走开，故选C。

43. C 推理判断题。根据He didn't have any food. Teleki wanted some fruit from a tree, but the tree was too tall. A young chimpanzee watched him curiously as he tried to get something to eat. The chimpanzee climbed the tree, picked the fruit, and gave it to him可知，泰莱基想要树上的水果，但是树太高了，一个小猩猩好奇地看着他，最后这个猩猩爬上树摘了水果送给了他，所以可以推断出泰莱基不会爬树，故选C。

44. B细节理解题。根据An elephant in Kenya hurt his trunk（象鼻子）. He needed help because he couldn't put food into his mouth可知，在肯尼亚，一只大象伤了它鼻子，因为它不能将食物送到嘴里，所以它需要帮助，。所以因为鼻子有伤，不能使用鼻子，故选B。

45. A代词指代题。代词代指上文中出现的内容。根据One day, a crocodile tried to eat a monkey that was next to a river. A hippo ran quickly to the crocodile and chased it away可知，鳄鱼想吃猴子，一个河马迅速跑向鳄鱼，将鳄鱼赶走，所以it代指的是鳄鱼。故选A。
