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 man's 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 time—sometimes several million years—and the extinction of one species is immediately followed by the appearance of anotherin a continuous cycle. The case of the dinosaurs is the most well－known 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 newspecies 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 pollutedsome habitats with chemicals and waste，making them unfit for wildlife.These causes ofextinction are known as indirect destruction. Animals may also become extinct through direct destruction.This includesthe hunting and catching of animals.Man has always hunted and killed wildlifebut 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，eggs—and sometimes just for amusement.Some species are still caught in the wild for the live pet trade，even though theirnumbers 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 withoutanyone knowing.【词海拾贝】1．extinction n．灭绝；绝种2．steadily adv.平稳地3．continuous adj.连续不停的；不间断的4．dominate v．支配；统治5．habitat v．栖息地6．destruction n．破坏【问题思考】阅读短文，判断正(T)误(F)。

Some experts believed that the cooling climate during the Ice Age was to blame for their extinction.Scientists reported last week they had studied genetic data from 59 cave bears. Their bones were recovered from seven countries: France, Germany, Italy, Poland, Serbia, Spain and Switzerland. From the genetic information, the scientists noted a decrease in the cave bear population beginning about 50,000 years ago. That is around the time of the arrival of Homo sapiens (现代人), or modern humans, in Eastern Europe. The researchers said they observed a sharp drop in the bears' numbers about 40,000 years ago. That coincides with(与……同时发生) the spread of Homo sapiens throughout Europe.The animals disappeared about 20,000 years ago. The cave bear lived in the Ice Age at the same time as other now extinct creatures. The bear was as big as a modern polar bear, but ate only plants. It appears often in prehistoric(史前的) cave paintings.There has been a scientific debate about what led to the extinction of the cave bear. Some scientists believe that the climate change greatly reduced the plants they needed, while others have blamed it on human activities, including hunting and taking over the caves where the bears gave birth and slept during winter. The bear's population remained largely unchanged for long periods before climate cooling, including during two noticeably cold periods and other cooling events.Homo sapiens appeared in Africa more than 300,000 years ago and later moved to other areas. The study offered new evidence that the arrival of Homo sapiens led to ruin for many kinds of animals across Eurasia, the Americas and Australia.1.How did scientists research on cave bears?A.By studying the bones found in some countries.B.By observing the paintings on the cave walls.C.By being told from generation to generation.D.By do research on the polar bears.2.When did the cave bear die out?A.About 50,000 years ago.B.About 40,000 years ago.C.About 20,000 years ago.D.More than 300,000 years ago.3.What can we learn according to the fourth paragraph?A.Sudden change in climate made cave bears die out.B.Cave bears couldn't adapt to the cold environment as quickly as possible.C.The loss of cave bears' habitats caused damage to their existence.D.Cold periods were very common thousands of years ago.4.Which of the following is the best title for the passage?A.Humans Are Perhaps Partly to Blame for Cave Bears' DisappearanceB.Homo Sapiens Hunting Kinds of Animals across EurasiaC.A Debate about Why Cave Bears Suddenly DisappearedD.Scientists Studied Bones Discovered in Seven CountriesB(2021河北邢台高一上期中,)It is widely believed that biodiversity (生物多样性) is promoted to save species. But in reality species exist only as part of ecosystems and cannot survive unless their ecosystems are protected along with the diversity they contain as much as possible.Protecting habitats is important for keeping biodiversity. In 2003, over 102,000 habitats covering nearly 19 million square kilometres, or 11.5% of theworld's land surface,were under some form of protection. Though this has been a great improvement since 1962, when just l,000 protected habitats were listed, it is still not considered enough to stop the ecocide that is endangering the world's biodiversity.For a number of environmentalists, protecting the world's 25 biodiversity hotspots(热点地区) is critical to saving habitats and species. But many hotspots are endangered already, having lost up to three-quarters of their original plants.The poor state of most biodiversity hotspots results directly from population growth and migration(迁移) into these areas. A study found that by the mid-1990s around 1.1 billion people had lived in these hotspots. Moreover, the annual population growth rate in these areas was 1.8%, higher than the global average of 1.4%. The PAI report concluded that human-related environmental changes would continue to put pressure on hotspots. Therefore, keeping biodiversity requires paying close attention to population size.Protecting hotspots is not simply a matter of putting up fences or employing guards. The best results will be achieved when local people are educated about the value of wildlife, and actually gain a share of the benefits from eco-tourism. Only then do they have a chance to see the benefits of protecting hotspots.5.What can we infer from Paragraph 1?A.The loss of any species can affect humans.B.Endangered species are paid more attention to by humans.C.Species can still survive when their ecosystems are destroyed.D.Ecosystem protection is as important as diversity protection.6.What does the underlined word “ecocide” in Paragraph 2 mean?A.Ecosystem protection.B.Reduction in the number of species.C.Serious damage to habitats.D.Habitat protection.7.What's the direct cause of the terrible state of the hotspots?A.Population growth in hotspots.B.Migration out of these areas.C.Global warming.D.The global average population growth rate.8.What's the author's opinion on protecting the hotspots?A.It's simple to carry out.B.It leads to the increase in tourists.C.It's closely connected with local people.D.It suggests that the local people be well educated.Ⅱ.七选五(2020山东德州高一上期末,)China has made great improvements in environmental protection during the past 70 years. 1 Each species on Earth has a role to play in the ecosystem.In recent decades,a series of wildlife-protection movements has been carried out by the central government. 2 The giant panda and the crested ibis(朱鹮) are among these successful stories.The giant panda used to have a population of 1,114 in the 1970s. It now totals 1,864 thanks to 52 protection areas. 3 By the end of last year, seven of the nine released pandas had survived in the wild. 4 In 1981,only seven crested ibises were found in Yang County,Shaanxi Province.Since then,breeding programs have helped the population reach 2,000. China has even sent crested ibises to Japan and South Korea in recent years to help with the species' survival.5 Key projects will be continually carried out to improveprotection,including making the lists of wild animals and plants under State protection,and also fighting against illegal wildlife trade, which includes the ivory(象牙)trade.A.Another species was once thought to be extinct.B.Protecting wildlife is, without doubt, an important part.C.China will continue its efforts in the wildlife protection.D.People call for immediate protection of the remaining species.E.Scientists have worked to feed pandas and then release them into the wild.F.As environmental damage has increased, signs of change have appeared around the world.G.Several species in danger of extinction have made impressive progress thanks to the methods.1. 2. 3. 4. 5.答案全解全析Part 1 Warming Up, Pre-reading, Reading &Comprehending基础过关练Ⅰ.1.decrease 2.hunt 3.certain 4.contain 5.affected6.employed7.appreciateⅡ.1.are being protected from 2.in peace 3.pay close attention to 4.burst into laughter 5.dying out 6.in relief 7.in danger ofⅢ.1.protection考查名词。
