1 Unit 4 Wildlife protection Ⅰ.阅读理解 A (2018安徽马鞍山模拟) The poaching, or the illegal killing, of rhinos (犀牛) in South Africa is growing worse each year. The government recently reported that a record number of rhinos were poached in 2014, a year which had more rhino killings in South Africa than ever before. The World Wildlife Fund, or WWF, says about 20,000 rhinos live in South Africa. They make up more than 80 percent of the rhinos in the world. Edna Molewa, South Africa’s Environment Minister, says, “During 2014, we are sad to say that, 1,215 rhinos were killed. This is a rise in the number of poached rhinos from 1,004 in 2013 and indeed very worrying.” The animals are hunted for their horns (角). Many people in Asia believe the horn has curing power, which drives poachers, at all costs, mad for more horns. But there is no scientific evidence for this belief. The horn is made of keratin. That is the same thing as human hair, fingernails and toenails. Ms. Molewa said 386 suspected poachers were arrested last year, an increase from the year before. But rhino protection workers say poachers often go unpunished after arrest. South Africa’s legal system is ineffective. Ms. Molewa said more needs to be done and South Africa is taking strong measures to protect rhinos. The efforts include moving some of the animals to secret places in neighboring countries. “Now approximately 100 rhinos have been moved to neighboring states in the SADC region during 2014 and 200 more rhinos will be moved this year,” Molewa said. Jo Shaw, the rhino program manager at the WWF, said, “We’re talking about a loss of a hundred rhinos a month, or more than three a day. We really need to see effective action not just at a national level but internationally.” She says officials should find the criminal groups responsible for the poaching and punish them. Government officials are 2
to meet in Botswana in March at the Inter-governmental Conference on Illegal Wildlife Trade. 1.What do we know about rhinos? A.Half of rhinos live in South Africa. B.Less than 1,000 rhinos were killed in 2013. C.The killing reached the highest point in 2014. D.There are only 20,000 rhinos left in the world. 2.What is the main reason for people to hunt rhinos? A.To get more keratin. B.To protect the farmland. C.To use them for decoration. D.To make money from horns. 3.Jo Shaw thinks that . A.many criminal groups are well-organized B.new laws are needed to punish the killers C.rhino protection needs international cooperation D.conferences about protecting rhinos are to be held every year 4.What can we infer from the text? A.Rhino protection has a long way to go. B.No one would like to buy horns in the future. C.The illegal killing of rhinos will soon disappear. D.Rhinos living in South Africa will move to other countries. B “De-extinction”,the idea that extinct(绝种的)animals can be brought back through cloning or genetic(基因的)engineering,has attracted the interest of a small group of scientists.The topic has made the cover of National Geographic Magazine. Supporters say they are doing it for moral reasons and because they “miss” the extinct animals.They blame the human exploitation of animals(such as hunting and the 3
destruction of wildlife habitat),but their plans,which sound exciting,are exploitation in another form. Considering the imperfect science of cloning,de-extinction would cause animals suffering.Most animals born of such experiments would suffer serious diseases,dying soon after birth or having a shortened lifetime.Spanish and French scientists worked for years to bring the Pyrenean ibex,a species of wild goat,back from extinction by cloning.In 2009,they succeeded only in producing a sick baby goat that died 10 minutes after birth.For the animals to be born,other animals would live in captivity,in a lab or elsewhere and serve as mother substitutes(代用品),routinely having operations as part of the cloning process.For example,elephants would be kept in captivity to carry woolly mammoth(猛犸象)babies for nearly two years.Such experiments often lead to other animals’ unhappiness. If extinct animals were successfully brought back,where would they go?Their original habitats have developed and changed. They are unlikely to survive in the natural environment now. But if they did manage to survive,they would affect their environment in unpredictable ways,presenting a new threat. If the animals born through de-extinction were raised in zoos and museums,what good would be that?It is exploitation,not a solution. It would be better to apply creative thinking about protection to the real-life problems of today’s world.De-extinction draws attention away from the difficult situation of endangered animals.Discussions about woolly mammoth cloning do nothing to stop the illegal endangered wild African elephant hunt. Money should be used to prevent the conflict between humans and wildlife. Let’s keep de-extinction in the world of science fiction,learn from our failed past,and protect wild animals and their habitats for the future. 5.The underlined word“it”in Paragraph 1 refers to “ ”. A.de-extinction B.cloning or genetic engineering C.exploitation
