Unit 4 Wildlife protection Using Language(ABOUT DINOSAURS)AimsTo read and listen about dinosaursTo speak about helping the dodoTo write to the dodoProceduresI. Warming up by reading to the tapeLet’s warm up by reading aloud to the recording of the textABOUT DINOSAURS on page 30.II. Listening about DINOSAURSNow I’d like to tell you something about DINOSAURS■In formation about DinosaurDinosaur means terrible lizard in Latin. They were called thatbecause people used to think dinosaurs were lizards, but they werenot. Dinosaurs first appeared about 200 million years ago. 65 millionyears ago, many kinds of dinosaurs became extinct. Birds are a special type of dinosaur and they were the only kind to live until today.There were many kinds of dinosaurs. Some ate plantsand some ate meat. The largest dinosaurs were plant-eaterslike apatosaurus and brachiosaurus. They were the largestanimals to ever walk on dry land.Other plant-eaters had special weapons to help them fight off the meat-eaters. For example, triceratops had three horns on its face, ankylosaurus was covered in boney plates, and stegosaurus had spikes on its tail.The meat-eaters all ran around on their back legs like people do. Some werevery large, like tyrannosaurus, and some were small, likecompsognathus. It was the smaller sized meat-eaters thatevolved into birds. One of the first birds was archaeopteryx,but it looked half like a dinosaur.There were large flying reptiles that lived at the same time as dinosaurs called pterosaurs, but they were not closely related to dinosaurs. There were also many kinds of large reptiles that could swim, like ichthyosaurs and plesiosaurs, but they weren’t closely related to dinosaurs either.III. Reading and copyingNext we shall go back to the text ABOUT DINOSAURS on page 30 again to read it and copy down all the expressions into your notebook.IV. Reading to answer questionsRead the questions in the table below and scan the text to answer them.V. Listening about the dodoHave you ever heard of the dodo, an animal that has also disappeared from the earth?The Mauritius Dodo (Raphus cucullatus, called Didusineptus by Linnaeus), more commonly just Dodo, was ametre-high flightless bird of the island of Mauritius. TheDodo, which is now extinct, lived on fruit and nested on theground.Next we are going to listen to the tape and do exercises 1 and 2 on page 30 on dodo.VI. Speaking in pairs about helping the dodoZhao Yannan: The Dodo was driven to extinction by sailors when theydiscovered the island of Maritius in the 17th century. It is one ofthe first documented human induced extinctions.Zhao Yanfei: What a pity that we can not find any dodo now.Imagine we are with the dodo, Yannan, what could we do to helpit?Zhao Yannan: Then I would intend to hide it in a cave, so that sailors could not find it.Zhao Yanfei: If I were there, I would try to trap them as they were catching and killing the dodo. Putting man who is harmful to the dodo in a cage and attacking him is the best way to protect and save the dodo.Zhao Yannan: I’d like to and I’m ready to, teach man how to be friends with animals, including the dodo. The man and the dodo can be living side by side on the earth. They can be happy together.ZhaoYanfei: I would rather not tell you what I think of man. He is selfish and cruel. He cares only for himself and that is why so many animals have disappeared from this earth. Putting the bad men in a cage is the only way out, I am sure.VII.

这些动物中最著名的就是恐龙。
数千万年前,恐龙在地球上生活,比人类的出现要早得多,那时,它们的未来似乎是安全的。
恐龙有许多不同的种类,其中有很多曾生活在中国。
25个种类的恐龙蛋是在河南省南阳西峡县发现的。
不久前,在辽宁省朝阳县发现了一种罕见的、形状像鸟的新的恐龙物种。
当科学家们观察它们的骨头时,他们惊奇地发现它们不仅能像其他恐龙一样可以跑,而且还可以爬树。
他们是从恐龙骨头的连接方式上得知这一点的。
大约6 500万年前,恐龙突然灭绝了。
一些科学家认为恐龙灭绝是发生在一次意外事件之后,当时太空中的一块巨石撞击地球,在空气中扬起了太多的灰尘。
另一些科学家则认为,地球变得太热了,恐龙无法再(在地球上)继续活下去了。
没有人确切地知道恐龙是为什么又是如何在那么短的时间内从地球上消失的。
我们知道最近有许多其他的野生植物、动物、昆虫和鸟类已经灭绝了。
根据联合国的一份报告,在过去的500年里,大约有844种动植物已经消失了,渡渡鸟就是其中的一种。
渡渡鸟生活在毛里求斯岛上,是一种非常友好的动物。
请听一个关于渡渡鸟的故事,看看它是如何从地球上消失的。
