But conservation (保护) of the African elephant faces special difficulties. While the elephant popu

10、lation 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

11、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 conservationland use. Elephants walk across borders and outside parks and othe

12、r 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 s

13、earching 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

14、 also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants. 1The first paragraph of the text is mainly to tell readers _.

17、elephants being endangered B Sharks have been swimming in the ocean for millions of years. 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 p

18、roblems 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 one

19、third 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 Shoo

20、ts 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 eate

21、n 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. 5What does the first paragraph

22、 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. 6According to Paragraph 2, sharks are in trouble because _. Athey often attack humans Btheir food is being poll

23、uted Cthey are being caught for food Dtheir habitat is being destroyed 7The underlined part “the practice” in Paragraph 3 refers to _. Ashark finning Bshark protection Cthe program of HIS Dthe exhibit at Beijing Zoo 8What do we know from the text? AThere are 400 shark species in the United States. B

24、Its illegal to eat shark fin soup in the United States. CMost sharks are not interested in a human for dinner. DSharks are very particular about their habitats and food. C The gentle giants of our oceans are whale sharks. Its the biggest whale shark and can reach as long as 41.5 feet, and these amaz

25、ing creatures are not only the biggest sharks, but they are also biggest fish of any kind. Whale sharks have a lifespan of 70 years on average, and they spend their days gently swimming in the warm and tropical oceans. Their teeth are the size of match heads, and while their jaws could be powerful,

26、they have never tended to attack humans. Their teeth play no role in eating, as plankton (浮游生物) does not need to be chewed. They are to be found in numbers in the warmer oceans and they prefer the deep waters of open oceans. They tend to travel alone. Several times a year they gather together in cer

27、tain spots where plankton is plentiful. Those areas are all within a 30 north or south latitude from the equator. Sadly whale sharks are targeted by commercial fisheries at those spots. How easy it must be for the fishermen to catch those beautiful creatures who can only swim at 3.5 miles per hour!

28、So great a loss in numbers have they suffered that whale sharks are now listed as one of the endangered species. Some countries have started to take measures to protect the whale sharks from extinction. The Philippines, India and Taiwan have all banned the fishing, selling, importing and exporting o

29、f whale sharks for commercial purposes. However, the law doesnt seem to be effective because the hunting and killing still goes on today, especially in Taiwan and the Philippines. Each whale shark can fetch around $21,000. In parts of Asia they are known as the “money shark” The mighty dollar wins a

30、gain at great cost to our habitat, and we will not know what we have lost until we have lost it forever. Therefore, it is high time for us to do something for the whale sharks. 9We can learn from the passage that whale sharks_. Ausually live a life of more than 70 years Balways travel in the ocean i

31、n groups Cdepend on their teeth to harvest their food Dlive in the deep waters of warmer oceans 10Why can the whale sharks be caught easily? ABecause they swim in the oceans at a slow speed. BBecause they are surrounded by so many fisherman. CBecause they often gather together. DBecause they never t

32、end to attack humans in the water. 11It is implied in the passage that_. Awhale sharks will be extinct even if they are protected Bwhale sharks are the most dangerous marine animals Cthere is no law about banning the fishing of whale sharks Dthe huge profit is to blame for the decreasing numbers of

33、whale sharks 12What is the main purpose of this passage? ATo appeal to people to protect whale sharks. BTo advise the government to make related laws. CTo guide people how to fish and kill whale sharks. DTo analyze the value of whale sharks. 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
