They were on Earth even before dinosaurs! At the top of the worlds oceans food chain, sharks help keep the population of other ocean animals in balance. A large drop in the number of sharks can cause serious problems for all ocean animals. Saving sharks makes sense!Many people are afraid of sharks. But most sharks are harmless. Only a small percentage of sharks are known to attack humans. It adapt (适应) well to new habitats and eat whatever is available. However, today, sharks are in trouble. Nearly onethird of the 400 shark species are in danger of extinction, largely due to overfishing. Each year, tens of millions of sharks are caught and killed just for their fins. The fins are used to make shark fin soup. Humane Society International (HSI) joined with the Jane Goodall Institutes Roots and Shoots program and Beijing Zoo to protect sharks. An exhibit at the zoo, “the Price Behind the TasteProtect Sharks. Dont Eat Shark Fins”， was designed to tell people that shark finning is cruel and unnecessary. Its hoped that the activity will help put an end to the_practice.Shark fin soup is also eaten in the United States. In fact, the numbers of some shark species in US waters have dropped 90 percent in the last 30 years. To slow the fall, laws against the sale of shark fins have been passed in several states, including Hawaii, Oregon, Washington, and California.篇章导读：本文是一篇说明文。如果美味的鱼翅是残忍杀害鲨鱼后获得的，你还能够接受吗？1What does the first paragraph mainly tell us?AOcean animals are at the top of the food chain.BSharks play an important role in the ocean.CSharks are an old species in the ocean.DSharks are being caught and killed.答案：B段落大意题。根据第一段中的“sharks help keep the population of other ocean animals in balance.

But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. Thats why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.Years ago, overhunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.The 21st century brings a different challenge to elephant conservationlanduse. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.篇章导读：本文是一篇说明文。非洲象的数量虽然有所增长，但对于非洲象的保护工作却不能停止。5The first paragraph of the text is mainly to tell readers _.AAfrican elephants are endangered nowBthere remains a lot to do to protect African elephantsCAfrican elephants are popular animalsDthe number of African elephants has increased over the years答案：B段落大意题。根据第一段可知，尽管目前大象的数量是40年前的一半，但是非洲有些地方的大象数量超过了此地区的供养数量。这就是AWF的科学家为什么要研究大象行为，保护大象栖息地，以及在非洲找到人与大象和平相处的方法的原因了。故第一段主要想告诉读者保护非洲象还有很多事要做。故选B。6What is the biggest difficulty in protecting African elephants now?AThey are still being killed.BTheir habitats are being destroyed.CThey dont have enough food.DThey cant live in peace with farmers.答案：D细节理解题。根据第三段内容可知21世纪非洲象的保护面临的新挑战是土地使用，大象经常破坏庄稼，导致当地农民和大象的冲突。故选D。7To protect elephants, the AWF does all the following EXCEPT _.Akeeping elephantsBprotecting elephants habitatsCdoing research on elephantsDhelping farmers improve their life答案：A细节理解题。根据最后两段可知，为了保护大象， AWF的研究者研究大象(搜集大象栖息地和行为的信息), 保护大象栖息地以及改进农民的生活。他们并没有饲养大象。故选A。8What is the best title for the text?AAfrican elephants conservationBLiving with African elephantsCAfrican elephants situationDAfrican elephants being endangered答案：A标题判断题。通读全文可知本文介绍了保护非洲象面临的问题以及保护策略。A项与文章大意相符，最适合作标题。故选A。应用文写作假定你是李华，当前濒临灭绝的动物数量日益增长，你作为校报小记者，刚刚进行了一次动物生存状况的调查，发现日常生活中我们有很多东西都与杀戮动物有关。请你根据以下要点在校报刊物上给全人类写一封英文信，号召大家保护动物。1很多人使用皮毛制品，靠猎杀动物挣钱；2为保护动物提出自己的建议；3发出倡议，号召大家一起行动起来保护动物。注意：1.词数100左右；2可以适当增加细节，以使行文连贯；3开头和结尾已给出，不计入总词数。Dear human beings，It is known that at present more and more wildlife is being in danger of dying out. Yours，Li Hua精彩范文Dear human beings，It is known that at present more and more wildlife is being in danger of dying out. According to my research, there are many reasons which lead to it. Some people like wearing clothes made from animals fur and others hunt animals to make money, and even some endangered species become our dishes.In order to prevent animals from extinction, we should first say no to the fur which is made into our clothes. In the second place, anyone who hunts animals for money should be punished. Finally, its necessary that the government set up more reserves to protect endangered species.Last, Id like to call on all of us to pay more attention to animals living conditions and work together to make sure they will not die out.Yours，Li Hua
