Animals are our friends.There are many many zoos in the 1. It's good to 2 animals in zoos.Zoos have many advantages, I think.

    Firstly, zoos are places for people to see 3 kinds of animals. Without zoos, most people would 4 see a real bear or tiger.

    5, zoos can take good care of animals. Zoos give 6 to animals and clean them on time every day. In the wild(在野外), it is not always easy for an animal to find food. So sometimes it goes 7^. But animals in zoos never go hungry.

    Thirdly, people protect the animals in zoos and offer them safe places to live 8^. Animals are living in zoos safely and happily. In the wild, some kinds of animals are 9 and are endangered(濒危的). But zoos give these animals a chance to live. Without zoos, there would be 10 kinds of animals in the world. People should do more things to protect animals.

    Thousands of bats(蝙蝠)in the Northeast are dying, and no one knows why. Scientists are conducting investigations(开展调查) to find out the cause and stop the spread of deaths, which have been most heavily reported in New York, Vermont and Massachusetts.

    "Most bat researchers agree that this is the most serious threat to bats they have ever seen, " says Alan Hicks, a bat expert who works in the New York Department of Environmental Conservation.

    There are few clues about the cause of the deaths. Bats are easy to catch the contagious disease(传染病) because they hibernate(冬眠) together. In some caves, there are 300 bats per square foot. Environmental officials are asking people to stay out of bat caves to avoid spreading the mysterious(神秘的) sickness while they are working to find out what it is.

    The largest animal living on the earth is the blue whale. It weighs about 80 tons—more than 24 elephants. It is more than 30 metres long. A newborn baby whale weighs as heavy as a big elephant.

    Cats can survive(存活) when they fall down from a very high place because they can keep their bodies safe. One cat fell 32 floors onto the street, but it was just hurt a little.

    A bear can run as fast as a horse.

    A newborn panda is smaller than a mouse, and weighs about 100 grams.

    Elephants are the most careful animals in their love. A male elephant may show his love to a lady for up to three years until the lady accepts his love. They often show their love by touching each other's body.

    Usually, wolves don't attack(攻击) people. And wolves don't usually go together, but they may do this in winter.

    Many people may think that a in the zoo are happy and lucky, but most of them are sad. Do you know why? Animals l tigers, lions and bears usually l in forests or mountains. They run, jump, play w their children and catch small animals for f. But now they have to stay in cages or small rooms in the z. They do not have to find food by themselves, because the zookeepers feed them. They do n but eat, walk and sleep every day. Their l in the zoo is quite d from that in the forests b they are not free.
