Unit 4Wildlife protection【导语】专家指出：地球上的动植物物种正以前所未有的速度消失，而无论是它们栖息地的丧失、污染，还是全球变暖带来的间接影响，祸根都源于人类。北部白犀牛小嘴狐猴Extinction is for ever!As almost everyone knows，to become extinct is to be gone for ever.Even before mans arrival on Earth，species became extinct quite naturally.Natural extinction happens when a species decreases in numbers gradually but steadily at the end of its evolutionary period on Earth.The length of this period depends on how well a species can get used to changes around it.This process of extinction can take a very long timesometimes several million yearsand the extinction of one species is immediately followed by the appearance of another in a continuous cycle.The case of the dinosaurs is the most wellknown example of natural extinction.They appeared on Earth about 200 million years ago and dominated both land and sea for almost 100 million years.It is not certain why the dinosaurs became extinct，but their disappearance was a natural one and new species of animals evolved to replace them.The rate of extinction has speeded up unnaturally over the last 400 years，rising sharply since 1990.This increase in the rate of extinction is directly related to the increase in the human population over the same period of time.The great number of humans has caused great damage to the planet，as wild habitats have been taken over，forcing animals and plants into smaller and smaller areas，until some of them have become extinct.We have also polluted some habitats with chemicals and waste，making them unfit for wildlife.These causes of extinction are known as indirect destruction. Animals may also become extinct through direct destruction.This includes the hunting and catching of animals.Man has always hunted and killed wildlife but when early humans lived more in harmony with nature，they killed animals for essential food and clothing.When firearms were invented，great destruction of species was possible.Animals have been，and still are，killed for meat，clothing，medicines，feathers，eggsand sometimes just for amusement.Some species are still caught in the wild for the live pet trade，even though their numbers are decreasing.The extinction of at least 500 species of animals has been caused by man.Today there are about 5，000 endangered animals and at least one species dies out every year.There are probably many more which become extinct without anyone knowing.【词海拾贝】1extinction n灭绝；绝种2steadily adv.平稳地3continuous adj.连续不停的；不间断的 4dominate v支配；统治5habitat v栖息地6destruction n破坏【问题思考】阅读短文，判断正(T)误(F)。1Before man arrived on Earth，species were

Hua答案：Dear_sir_or_madam，Im_writing_to_give_some_suggestions_to_protect_the_wildlife_living_in_and_around_our_city.As we know，many species of wildlife are in danger of extinction now，which results from the environment that they are living in has been destroyed greatly.With the development of cities，water and air are seriously polluted.Their living areas are becoming smaller and smaller.They not only are lack of food，but also are killed by human beings.These species of wildlife are important part of our life.Personally，more measures should be taken to protect them from being hunted.Firstly，more laws must be made to stop people from cutting down trees.Secondly，all the factories must clean the waste water before it is poured into rivers or lakes.Thirdly，more reserves should be set up so that they can live safely.I hope you will find my suggestions helpful.Yours_sincerely，Li_Hua.语法填空在句中空白处填上适当的内容(1个单词)或括号内单词的正确形式。1He felt nervous with the whole class _ (look) at him.2You must understand _

this way they are like other animals，such as bees and birds.But dolphins are very different from almost all land animals.Their brain is nearly the same size as our own，and they live a long timeat least twenty or thirty years.Like some animals，dolphins use sound to help them find their way around.They also make these sounds to talk to each other and to help them find food.We now know they do not use their ears to receive these sounds，but the lower part of the mouth，called the jaw.Strangely，dolphins seem to like man，and for thousands of years there have been stories about the dolphin and its friendship with people.There is a story about sailors in the 19th century.In a dangerous part of the sea off the coast of New Zealand，they learnt to look for a dolphin called Jack.From 1871 to 1903 Jack met every boat in the area and showed it the way.Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack.He recovered and for nine years more continued to guide all ships through the areaexcept for The Penguin.Today，some people continue to kill dolphins，but many countries of the world now protect them and in these places it is against the law to kill them.【语篇解读】海豚是一种聪明的海洋生物，它经常帮助人们，我们人类应该保护它们。1Which of the following does the dolphin use to help it find its way around?AIts nose.
