让我们合作互助How much do you know about manatees? Manatees are very gentle and shy. Their habitat is the water under the trees in mangrove swamps The average manatee is about 10 feet long and weighs about 1000 pounds. A manatee needs about 100 pounds of aquatic feed (underwater plants and vegetation )a day. There used to be a lot of manatees,but now there aren’t very many of them.

3b Read this letter to the editor. What’s “Animal Friend”opinion about the zoo? Educate 教育 care for 关怀 urge 强烈要求He thinks that the zoo is an important place for the animals. And it is like a living textbook for young people.Dear editor:
After reading the two letters, I realize that I must say something about animals and zoos． I don’t agree with Disgusted．In fact, many animals only eat once a day or once every few days, so feeding them just once a day is not a problem at all． I think zoos are very important to animals. They can stop many endangered animals from being killed or hunted．They can provide man with places for research work．Also we can visit the animals in the zoos to learn some knowledge to protect the animals better．
Sincerely,
JennyWrite a letter to the editorDebate: Do you think zoos are good for animals?Useful expressionsI think that animals should not live in zoos.
I disagree with you. I
feel that zoos provide clean
and safe places for
endangered animals to live.Firstly zoos are places for people to see many different kinds of animals from all over the world. Secondly, zoos look after the animals very well. Thirdly, zoos protest the animals and keep them from becoming extinct. Pros:Cons: Most animals are kept in small cages. Most cages are not clean, either. The food in the zoos is not natural. In the forest they can find the food by themselves.Summary Exercises I : 根据汉语完成下列句子.我反对在我们镇上建新的动物园.
我发现那里几乎没有人,我感到非常惊讶.
他们为许多濒危动物提供家园,并且帮助教育公众关心它们.
我强力要求每个人参观我们的动物园.
