2 . Biologist Marc Bekoff studies dogs, wolves and coyotes.     1    . If they’re in the same pack, animal friends may sleep close to one another. They greet one another, travel together, share food and groom each other. Animal friends are nice to one another, and they even play together.    2    .

Playing together, for instance, helps animals bond and keeps them close to the group. “Coyote pups who don’t play together are more likely to go out on their own.    3    .” says Bekoff. “If an animal has a special friend, both friends benefit by having someone to watch out for them.”

    4    . When a young rhinoceros sets out on its own for the first time, it may look for an older travel friend, and this companion helps to find food and water and avoid predators. Young male elephants hang out together when they leave their mothers’ herds, and young dolphins do, too. Pairs of bottlenose dolphins sometimes form strong bonds and pal around together for years. Among chimpanzee groups, some pair up to groom each other, hunt together, share food and defend each other from danger.

Why do animals have friends? “Mainly because in the long run they benefit from friendships,” scientist Franz de Waal says. “It is all give and take.    5    .”

A．Young animals often team up for protection

B．He believes that many animals do have friends

C．He thinks that many animals seldom have friends

D．Therefore, playing together sometimes is harmful

E．And leaving the protection of the group can be dangerous

F．This friendly behavior can be important to an animal’s survival

G．Sometimes one gives more, the other takes more, but in the end both parties gain

3 . As the air cools and sunlight decreases each fall, thousands of western monarch butterflies (帝王蝶) return to California to spend winter. One of the best places to watch the colorful scene is Pismo Beach.

From now through February, over 10, 000 will fly to trees at Pismo Beach Monarch Butterfly Grove, one of five locations in the state to host so many of the colorful creatures. Just like tourists, the western monarchs prefer the sunny and warm conditions of the beachside state park.

The migration peaks in November, when the last of the western monarchs settle into the trees at Pismo Beach Monarch Butterfly Grove. Some have flown over 1, 000 miles from as far away as Canada to escape winter's low temperatures. The butterflies gather on tree branches, where they mostly remain sitting, until sunlight bathes the trees and the western monarchs begin to beat their wings. Activity reaches its peak in February.

While this annual sight is wonderful, it pales in comparison to what used to be. Millions of western monarch butterflies used to spend winter in California and Mexico only a few decades ago. Climate change, loss of natural habitat and harmful chemicals are just a few of the environmental threats that have caused a more than 99% decrease in populations since the 1980s, according to a research.

“In monarchs’ overwintering trees, there were once so many butterflies that the sound of their wings was described as a summer rain,” states the Center for Biological Diversity. “Early newspaper descriptions described branches breaking under the weight of so many butterflies.”

Conservation efforts are underway in several states, including California, to help restore populations of monarch and western monarch butterflies. However, it is unknown how successful these attempts will be. Scientists are concerned about the possibility of a complete collapse of the species since numbers have dropped so dramatically in the last few years.

4 . A mobile(移动的)hospital for treating injured wildlife has just begun a journey to its new base in Byron Bay, on Australia's east coast.

Byron Bay Wildlife Hospital founder and Professor Stephen Van Mil said that Australia's annual disastrous(灾难性的)wildfire season could _______ the animals’variety. Seeing the _______ koalas sitting in baskets waiting for care was _______ .

5 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Ever since he was a kid, Colin had taken great interest in hiking (远足）. To celebrate his 40th birthday, he planned to climb Mountain Sunshine.

The night before his journey, Colin filled his backpack with hiking poles, a homemade hamburger, and some other necessities. He drove off at 7 am the next day, his mountain bike in the trunk(后备箱）。When he was already on the way, he suddenly realized there was a possibility of bear attack.

About an hour later, he arrived at a camp and checked in.“Is there anything you need?”Vito,the camp manager, asked him.

“Bear spray(驱熊喷雾），”said Colin.

After finding a bottle, Vito offered him a ride. They trucked along a road until the forest got too thick. As Colin put his mountain bike against a bush so that he could recover it on the way back, Vito said, “I'll come for you if you're not back when the night falls." “Nothing to worry about,” Colin replied in a confident voice.

With the bear spray in one pocket,Colin started hiking.He marked his trail(足迹，踪迹） and made lots of noise to drive away any curious animals.

Before he knew it, it was getting dark. Not wanting to get caught in the dark, and satisfied with what he'd finished that day, he started to climb down the mountain, and soon recovered his bike.

As he passed a marker showing 3 kilometers away from the camp, he suddenly stopped his bike-a bear stood in the middle of the narrow road,some hundred meters away. Knowing it could easily attack him if he sped up, Colin decided not to anger the bear.
