F 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 at first we seemed to be good friends. We went everywhere together and I shared my food with him. Listening text However, 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 told me, “Your friends are being killed and eaten by Man while you are hunting for food.” Had Man eaten them? I couldn’t believe it! When I asked Man directly, he seemed surprised. “I haven’t seen the other dodos either.” he said. “Maybe someone else killed them.” I believed him but when more dodos disappeared 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 Man’s spear . He killed me too. After that there were no more dodos in the world. So my motto is: be careful who you trust. 渡渡鸟 是一种不会飞的鸟 , 仅产于非洲的岛国 毛里求斯。肥大的体型总是使它步履蹒跚 , 再加上 一张大大的嘴巴 , 使它的样子显得有些丑陋。幸好 岛上没有它们的天敌 , 因此 , 它们安逸地在树林中 建窝孵卵 , 繁殖后代。 16 世纪后期 , 带着来复枪和猎犬的欧洲人来到了 毛里求斯。不会飞又跑不快的渡渡鸟厄运降临了。 欧洲人来到岛上后 , 渡渡鸟就成了他们主要的食物 来源。从这以后 , 枪打狗咬 , 鸟飞蛋打 , 大量的渡渡 鸟被捕杀。就连幼鸟和蛋也不能幸免。开始时 , 欧洲人每天可以捕杀到几千只到上万只渡渡鸟 , 可是由于过度的捕杀 , 很快他们每天捕杀的数量 越来越少 , 有时每天只能打到几只了。 1681 年 , 最后一只渡渡鸟被残忍的杀害了 , 从此 , 地球上再也见不到渡渡鸟了 , 除非是在博物馆的 标本室和画家的图画中。 Speaking and writing It is a pity that in the story nobody helped the dodo. In pairs choose another endangered animal which you know about. Analyze why this animal is endangered. Is it being hunted and killed? Does it not have enough food? Is it because its habitat is being threatened? Some endangered animals: the African elephant whale rhino golden monkey Intention Purpose I’m going to to help/ save… I intend/mean/plan to to protect … from … I will so that I feel like in order to … I’d like to but do … I’m ready to to teach them a lesson I’d rather not to punish those who do harm to wildlife. S1: I’m 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 would do harm to dodo. Sample And I’d 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 can’t agree with you more. Man hunts all kinds of animals to make clothing, to eat their meat and even to get their bones cruelly. I’d like to see we humans treat them as our friends. Write a letter to WWF based on what you have discussed, asking them to help you save your endangered animal. All letters have a start and ending. Writing Formal Informal Starts Dear Hi, My dear, Dearest, Endings Yours sincerely, Sincerely, Sincerely Yours, Yours truly, Yours faithfully, Love, Cheers, Regards, Best whishes, Yours, Step 1: Collect your ideas for the letter and write down as notes. Step 2: Begin your letter like this: Dear WWF, … Step 3: Finish the letter by writing : Yours sincerely. (your name) Step 4: Check your writing and share your ideas with the class by reading them aloud. 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 that 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 think 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 sincerely Wu Xiao Xing We have only ONE earth! Homework Finish exercises in Workbook. 2.
