region so as the ice is ‎ 7‎ melting,their natural habitat can be seriously affected.These changes don’t take place overnight.They can be the result of many years of additional temperatures in the area.The seals then have to find ways to adapt.‎ Seals depend on the cool air currents to bring plenty of food for them.When the temperature get higher there is less and less food and the seal population starts to shrink.Mothers aren’t healthy enough to feed their babies.Many of them end up abandoned as the mothers have to leave to find their own source of food.‎ The fact that their desire to produce young can be changed by the warmer temperature is frightening too.It is also believed that the warmer temperature can allow different diseases and viruses to attack the seals.This is a huge concern as they can rapidly wipe out huge numbers of seals out there.‎ However,these changes in climate and temperature aren’t all bad for other species of seals.Scientists have found that those living in warmer climates are producing more young due to the changes.Research also shows that the females are moving further to find food and water.When they are out of the reach of the governing males,they are more willing to accept the moves of other males in the group.‎ This is good news too because it means that there will be more selection in the gene pool(基因库)for future generations.It can help the seals as a species adapt to changes in their natural environment more easily.‎ The climate change problem for seals is directly linked to humans.When we take action to change what we let out into the environment,we will make positive changes for the seals.However,it is going to take a very long time to reverse (彻底改变)the effects of what has already been done.‎ ‎【语篇导读】本文主要介绍了气候变暖对南极地区海豹的影响。‎ ‎1.What does the author regard climate changes for seals as?‎ A.A double-edged sword.‎ 7‎ B.An unavoidable disaster for existence.‎ C.A mirror of evolution.‎ D.A requirement for more choice in the gene pool.‎ 答案A 解析推理判断题。文章第一至三段介绍了气候变暖对南极地区海豹的负面影响,第四、五段介绍了气候变暖对其他海豹种类的正面影响。由此可知,在作者看来,气候变暖对海豹有利有弊,是把双刃剑。‎ ‎2.What will happen to the seals in warmer climates?‎ A.Their number will be on the increase.‎ B.The female seals will be in the lead.‎ C.Their genes will change a great deal.‎ D.The females will keep away from the males.‎ 答案A 解析细节理解题。根据第四段中的“...thoselivinginwarmerclimatesareproducingmoreyoungduetothechanges.”可知,生活在更暖和地区的海豹会因为天气变暖而繁殖更多的幼崽。换言之,它们的数量会增加。‎ ‎3.Which of the following can be the best title for the text?‎ A.The Importance of Protecting Seals B.Seals’ Adaptation to Climate Change C.How Climate Change Affects Seals D.Why Are Seals Becoming Less and Less 答案C 解析主旨大意题。根据全文可知,介绍了气候变暖对南极地区海豹的负面影响和正面影响,因此C项“气候变化如何影响海豹”可概括全文的主旨。‎ Ⅳ.应用文写作 7‎ 据报道,藏羚羊(Tibetan antelope)受非法捕杀而濒临灭绝,总数从1990年的100万只锐减到现在不足10万只。假设你是李华,现请用英文给中国野生动物保护协会CWCA(China Wildlife Conservation Association)的会长写一封建议信。内容应包括:‎ ‎●简述藏羚羊的现状;‎ ‎●陈述原因(取羊皮获利等);‎ ‎●提出你的建议(加大宣传力度、增加资金、选派志愿者等)。‎ 注意:‎ ‎1.词数80左右;‎ ‎2.开头和结尾已给出,不计入总词数;‎ ‎3.可根据内容需要适当增加细节。‎ Dear President,‎ I’m writing to give some suggestions to further protect the Tibetan antelope. ‎ ‎ ‎ ‎ ‎ Looking forward to your reply.‎ Yours sincerely,‎ Li Hua 参考范文 Dear President, ‎ I’m writing to give some suggestions to further protect the Tibetan antelope.As is often reported,too many Tibetan antelopes are being hunted and killed illegally for their fur,from which the illegal hunters can make great profits.As a result,the number of the Tibetan antelopes is decreasing rapidly from about 1,000,000 in 1990 to less than 100,000 at present. ‎ Immediate measures must be taken to improve the present situation.Firstly,the importance of protecting the Tibetan antelopes should be promoted.Secondly,would you ‎ 7‎ provide more money for the conservation of the Tibetan antelopes? Last but not least,I suggest that some volunteers be sent there to help protect the Tibetan antelopes.‎ These are my suggestions and I hope they could mean something for a better future of the Tibetan antelopes.‎ Looking forward to your reply. ‎ Yours sincerely, ‎ Li Hua ‎ Ⅴ.概要写作 阅读下面短文,根据其内容写一篇60词左右的内容概要。‎ The largest land animal remaining on the earth,the African elephant is of much importance to African ecosystem.Unlike other animals,the African elephant is to a great extent the builder of its environment.As a giant plant-eater,it significantly shapes the forest-and-savanna(大草原) surroundings in which it lives,therefore deciding the conditions of existence for millions of other animals that live in its habitat.‎ It is the elephant’s great desire for food that makes it both a disturber of the environment and an important builder of its habitat.In its continuous search for the 300 pounds of plants it must have every day,it kills small trees and underbush,as well as pulls branches off big trees.This results in numerous open spaces in not only deep tropical forests but also the woodlands that cover part of the African savannas.In these open spaces are numerous plants in various stages of growth,which attract a variety of other plant-eaters.‎ Take the rain forests for example.In their natural state,the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.By pulling down trees and eating plants,elephants create open spaces,allowing new plants ‎ 7‎ to grow on the forest floor.In such situations,the forest becomes suitable for large-hoofed plant-eaters to move around and for small-sized plant-eaters to obtain their food as well.‎ Scientists are worried now that the African elephant has become an endangered species.If the elephant dies out,scientists say,many other animals will also disappear from vast areas of forest and savanna,greatly changing and worsening the whole ecosystem.‎ ‎ ‎ ‎ ‎ ‎ ‎ 参考范文 The African elephant is essential for African ecosystem.(要点1) By consuming quantities of plants in its habitat,the elephant produces enough room for abundant new plants,then feeding various animals.(要点2) Thanks to elephants,rain forests are less dense,which is more proper for mutual survival of creatures.(要点3) Once the African elephants go extinct,the entire ecosystem will be threatened.(要点4)‎ 7‎
