UNIT 1 Nature in the balance1．Be kind to animals and live in harmony!善待動物，和諧生存！2．Protect animals and maintain ecological balance.保護動物，維護生態(tài)平衡。3．Clear waters and green mountains are as valuable as mountains of gold and silver.綠水青山就是金山銀山。4．Share nature with the earth!同在地球上，共享大自然！5．Care for life，stop killing，we have a common planet.關(guān)愛生命，停止殺戮，我們擁有一個共同的地球。6．It's everyone's duty to love and protect the environment.愛護和保護環(huán)境是每個人的責任和義務。It is very important for us to keep the balance of nature，and nature often teaches its lessons.Here are two examples.The first one is eagles eat chickens.They eat mice as well.The farmers want to kill many eagles to protect their chickens，but to their surprise，more and more mice appeared.A lot of grains were eaten.The second one is in one place in America，the deer eat a kind of wild rose，while the mountain lions eat the deer.People killed many mountain lions to protect the deer.As a result，the deer ate up all the wild roses and began to eat the green leaves and young trees.Now you can see how important it is to keep the balance of nature.If we don't keep the balance of nature，we will suffer from it.As we all know，animals are humans' best friends. Animals are valuable resources(資源) that are helpful to us all through our history.However，many kinds of animals are in danger now! Animals have been killed for their fur，for food，for entertainment，and simply because they are in the way.Thousands of kinds of animals have disappeared from the earth forever so far.Hundreds more are on the danger list today.About 170 kinds in the United States alone are considered in danger.It is high time that we should pay more attention to how to protect these animals on the earth.Why should we care about the animals in danger？Because animals help us a lot and we need animals.Once they are gone，there will never be any more.Animals are more than just beautiful or interesting.They are more than just a source of food.Every animal has its place in the balance of nature.Destroying one kind of animal can create many problems.Luckily，some people are working to help save the animals.Some groups raise money to let people know about the problem.And they try to get the governments to pass laws protecting animals in danger.Quite a few countries have passed laws.These laws forbid the killing of any animal.Slowly，the number of some animals in danger is growing.Everyone should try to protect animals and treat them well.[探索發(fā)現(xiàn)]1．Find out the main idea of the passage.The passage is mainly about why and how we protect our best friends—animals.2．Find out why we should care about the animals in danger.Because animals help us a lot and we need animals.3．Find out what we can do to protect and save the animals in danger.First，raise the people's awareness of protecting animals；second，ask the government to pass the laws protecting the animals.
