1、Unit 4 Wildlife protection 教学设计Period 1: Warming up and readingTeaching AimsTo talk about endangered speciesTo read about wildlife protectionProceduresI. Warming up by learning about animalsLook at the photos below and listen to me telling you about the animals, the endangered animals. The Giant Pan
2、da is a mammal now usually classified in the bear family, beside, that is native to central China.The Giant Panda lives in mountainous regions, like Sichuan and Tibet. The Giant Panda is the symbol of the World Wildlife Fund (WWF), a conservation organization. Toward the latter half of the 20th cent
3、ury, the panda also became somewhat of a national emblem for China, and is now used in Chinese gold coins.Giant Pandas are an endangered species, threatened by continued loss of habitat and by a very low birthrate, both in the wild and in captivity. About 1,600 are believed to survive in the wild.Mi
4、lu deer is a Chinese deer. It has a long tail, wide hooves, and branched antlers. Another Chinese name for it is “four unlikes,.” because the animals were seen as having the horns of a stag, the neck of a camel, the foot of a cow, and the tail of an ass. These animals were first made known to Wester
5、n science in the 19th century, by Father Arm and David, a French missionary working in China. At the time, the only surviving herd was in a preserve belonging to the Chinese emperor. The last herd of Milu deers that remained in China were eaten by Western and Japanese troops that were present at the
6、 time of the Boxer Rebellion.These deer are now found in zoos around the world, and a herd of Milu deer was reintroduced to Dafeng Reserve, China in the late 1980s. They are classified as “critically endangered.” in the wild, but do not appear to have suffered from a genetic bottleneck because of sm
7、all population size.A tiger is a large cat famous for its beautiful fur of orange striped with black. Tigers live in Asia and are becoming very rare. This is due to people hunting them for their fur and destroying the forests they live in.II. Pre-reading1 Defining wildlifeWhat does the world wildlif
8、e mean?The term wildlife refers to living organisms that are not in any way artificial or domesticated and which exist in natural habitats. Wildlife can refer to flora (plants) but more commonly refers to fauna (animals). Needless to say, wildlife is a very general term for life in various ecosystem
9、s. Deserts, rainforests, plains, and other areasincluding the most built-up urban sitesall have distinct forms of wildlife.Humankind has historically tended to separate civilization from wildlife in a number of ways; besides the obvious difference in vocabulary, there are differing expectations in t
10、he legal, social, and moral sense. This has been reason for debate throughout recorded history. Religions have often declared certain animals to be sacred, and in modern times concern for the environment has provoked activists to protest the exploitation of wildlife for human benefit or entertainmen
11、t.2. Make a list of other endangered wildlife in China that is being protected.3. Pre-reading questions:4. Reading to the recordingNow turn to page 26, listening and reading to the recording of the text. Try to keep pace with the native reader, making your reading resemble that of the reader, in spe
12、ed, in intonation and in pronunciation. III. Reading1 Reading and getting informationNow you are to read the text for information to fill in the form.Animal Problem Solution1 antelope hunted for its fur not given2 elephant killed for its habitat farmers paid to promote tourism, not kill elephants3 m

Closing up by matching animals to five risk categories Different endangered species
15、appear on different endangered species lists. And people who are trying to protecting animal use the following five risk categories to group the unlucky animal.Now in groups of four try to group all the unlucky animals found in China.List of Unlucky animals found in China 中国不幸动物分类名录EXTINCT(灭绝动物)-A s

17、.THREATENED（危急动物）-A species likely to become endangered in Canada if the factors affecting its vulnerability are not reversed.VULNERABLE（弱势动物）-A species particularly at risk because of low or declining numbers, small range or for some other reason, but not a threatened species.Period 2: Learning abo
18、ut LanguageTeaching AimsTo learn about The Present Progressive Passive VoiceTo discover useful words and expressionsTo discover useful structures.ProceduresI. Warming up by acting a text playGood morning class. To begin with we shall put our text HOW DAISY LEARNED TO HELP WILDLIFE on stage, that is,
19、 to act out our story. Now the class acting team with their text play of HOW DAISY LEARNED TO HELP WILDLIFE!II. Discovering useful words and expressions1. Doing vocabulary exercisesTurn to page 28 and do the vocabulary exercises 1, 2 and 3. You can simply write your answers in the blanks on the very
20、 page of 28.2. Playing a gameLets go on to play the game described on the top of the page 29. The following sentences are to be passed on. Plant native plants in your backyard. Do not dump weeds in the bush. Build a frog pond in your backyard. Put your rubbish in the bin. Leave your pets at home. Do
21、 not take anything out of the park. Encourage your friends to keep patches of bush as wildlife habitats. Join a community group and offer to do voluntary work. Find out about conservation activities happening in your local area. Participate in local clean-up, tree planting and weed control activitie
22、s. Learn About Threatened Species Look out for wildlife Refuse to buy any rare or endangered plant or animal product. Be alert and drive slowly at dawn and dusk in rural areas where wildlife may be active. III. Studying The Present progressive Passive Voice1. Passive Voice The passive voice is used
23、when focusing on the person or thing affected by an action. The Passive is formed: Passive Subject + To Be + Past Participle It is often used in business and in other areas where the object of the action is more important than those who perform the action. For Example: We have produced over 20 diffe
24、rent models in the past two years. Changes to: Over 20 different models have been produced in the past two years. If the agent (the performer of the action) is important, use “by.” For Example: Tim Wilson wrote The Flight to Brunnswick in 1987. The Flight to Brunnswick was written in 1987 by Tim Wil
25、son. Only verbs that take an object can be used in the passive. The following chart includes sentences changed from the active to the passive in the principal tenses. Active Passive Time Reference They make Fords in Cologne. Fords are made in Cologne. Present SimpleSusan is cooking dinner. Dinner is
26、 being cooked by SusanPresent ContinuousJames Joyce wrote Dubliners. Dubliners was written by James Joyces.Past SimpleThey were painting the house when I arrived. The house was being painted when I arrived.Past ContinuousThey have produced over 20 models in the past two years. Over 20 models have be
27、en produced in the past two years.Present PerfectThey are going to build a new factory in Portland. A new factory is going to be built in Portland.Future Intention with Going toI will finish it tomorrow. It will be finished tomorrow. Future Simple2. Passive Verb FormationThe passive forms of a verb
28、are created by combining a form of the “to be verb.” with the past participle of the main verb. Other helping verbs are also sometimes present: “The measure could have been killed in committee.” The passive can be used, also, in various tenses. Lets take a look at the passive forms of “design.”Auxil
29、iaryTense Subject Singular Plural Past Participle Present The car/cars is are designed. Present perfect The car/cars has been have been designed. Past The car/cars was were designed. Past perfect The car/cars had been had been designed. Future The car/cars will be will be designed. Future perfect Th
30、e car/cars will have been will have been designed. Present progressive The car/cars is being are being designed. Past progressive The car/cars was being were being designed. IV. Reading and identifyingSince you are clear about Passive Verb Formation, go back to page 26 and scan the text for all the
31、examples of The Present Progressive Passive Voice. Were being killed for the wool beneath our stomachs.Our fur is being used to make sweaters for people like you.Now try to put the following sentences into The Present Progressive Passive Voice. They are producing this new drug. Antelope is looking a
32、t her. They are killing us for the wool. They are destroying the farm.V. Discovering useful structuresTo consolidate your learning of The Present Progressive Passive Voice, turn to page 29 and do the grammar exercises 2 and 3.VI. Closing down by playing a gameTo end this period go to page 29 and pla
33、y the game called “Tell me what is happening?” Ask questions containing The Present Progressive Passive Voice. Period 3: Using Language Teaching AimsTo read and listen about ANIMAL EXTINCTIONTo speak about helping the dodoTo write to WWFProceduresI. Warming up by reading to the tapeLets warm up by r
34、eading aloud to the recording of the text ANIMAL EXTINCTION on page 30.II. Listening about ANIMAL EXTINCTIONNow Id like to tell you something about DINOSAURS and finish exercise 3 and 4 on page 30.Have you ever heard of the dodo, an animal that has also disappeared from the earth?The Mauritius Dodo
35、(Raphus cucullatus, called Didus ineptus by Linnaeus), more commonly just Dodo, was a metre-high flightless bird of the island of Mauritius. The Dodo, which is now extinct, lived on fruit and nested on the ground.Next we are going to listen to the tape and do exercises 2 and 3 on page 30 on dodo.In
36、formation about DinosaurDinosaur means terrible lizard in Latin. They were called that because people used to think dinosaurs were lizards, but they were not. Dinosaurs first appeared about 200 million years ago. 65 million years ago, many kinds of dinosaurs became extinct. Birds are a special type
37、of dinosaur and they were the only kind to live until today.There were many kinds of dinosaurs. Some ate plants and some ate meat. The largest dinosaurs were plant-eaters like apatosaurus and brachiosaurus. They were the largest animals to ever walk on dry land.Other plant-eaters had special weapons
38、 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 were very large, like tyrannosaurus, and some were sm
39、all, like compsognathus. It was the smaller sized meat-eaters that evolved 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 dinosa
40、urs. There were also many kinds of large reptiles that could swim, like ichthyosaurs and pleisiosaurs, but they werent closely related to dinosaurs either.III. Reading and copying Next we shall go back to the text ABOUT DINOSAURS on page 30 again to read it and copy down all the expressions into you
41、r notebook.Useful phrases from ABOUT DINOSAURSDuring the history of the earth, live on the earth, tens of millions of years ago, came into being, eggs of five species, a rare new species, a bird-like dinosaur, climb tree, tellfrom, die out, hit the earth, putinto the air, get hot, live on, know for
42、sure, in the same way, listen to the story about, disappear from IV. Reading to answer questionsRead the questions in the table below and scan the text to answer them.When did dinosaurs live on earth?When did dinosaurs die out?How did dinosaurs die out?V. Speaking in pairs about helping the dodoZhao Yannan: The Dodo was driven to extinction by sailors when they discovered the island of Maritius in the 17th century. It is one of the first documented human induced extinctions.
