17、rcises in Workbook inpage 65.章丘市第七中学章丘市第七中学20152015年年3 3月月1818日日The story of the dodo Once upon a time I lived on the island of Mauritius.I was called“dodo”.There were many of us and we were friends with all the other animals on the island.One day a new animal came to my island.His name was Man,and

18、at first we seemed to be good friends.We went everywhere together and I shared my food with him.Listening textHowever,I began to wonder why several of my dodo friends had disappeared.Then the number of our species began to decrease quickly.I was so worried that I asked the other animals and they all

19、 told me,“Your friends are being killed and eaten by Man while you are hunting for food.”Had Man eaten them?I couldnt believe it!When I asked Man directly,he seemed surprised.“I havent seen the other dodos either.”he said.“Maybe someone else killed them.”I believed him but when more dodos disappeare

20、d I set a trap.I went off as if I was going to hunt but instead I hid in the forest and waited.Sure enough Man came along.He ran after the last of my dodo friends and killed her.I felt so angry that I rushed out of my hiding place and straight at Mans spear.He killed me too.After that there were no

21、more dodos in the world.So my motto is:be careful who you trust.S1:Im going to do something to help dodo,for it was so lovely.I mean to drive it away in order to hide it in a cave.And I will dig a hole at the gate of the cave to trap man as he kills a dodo.I feel like attacking man myself if they wo

22、uld do harm to dodo.SampleAnd Id like to teach man how to be friends.I would rather not tell you what I think of man.In fact man is the most dangerous enemy of dodo and all the endangered animals.S2:I cant agree with you more.Man hunts all kinds of animals to make clothing,to eat their meat and even

23、 to get their bones cruelly.Id like to see we humans treat them as our friends.Dear WWF,My friend,Chen Lin,and I have been doing some research on endangered animals.We found that the habitat of polar bears is disappearing because the ice at the North Pole is getting warmer.Sample writing:I worry tha

24、t when is disappears altogether,there will be nowhere for the polar bears to live.First,I suggest we are very careful with the energy we use.Global warming happens because we are putting too much carbon dioxide into the air.One of the ways we do this is by driving everywhere by car.So I suggest we t

25、hink carefully before using our cars unnecessarily.Second,instead of using our cars we should think about traveling by bus or by train.These forms of transport are more environmentally friendly and do not put so much carbon dioxide into the atmosphere.Third,we can join WWF which is fighting to save the habitat of the polar bear.We can raise money to help them by making and selling cakes,selling crafts or giving talent shows and charging money for our parents to watch.I hope you will support us in our fight to save the home of the Polar Bears.Yours sincerelyWu Xiao Xing
