课后分层集训Unit 2The environment (A卷).阅读理解A(2017沈阳市高三教学质量检测)In 2013 alone at least 20，000 African elephants were killed for their teeth.In South Africa over the last two years more than 2，200 rhinos were killed for their horns.These numbers are alarming，because current rates of illegal hunting are faster than birth rates，which could lead to extinction of these ecologically important creatures in the environment.Indeed，some elephant and rhino populations are on track to be locally extinct within the next decade.If you are reading this，you may already be aware of these facts.But you might not know that wildlife trafficking(非法交易) not only threatens the existence of elephants and rhinos but is also leading to extinction of other species，such as tigers，tortoises，sea turtles，and the worlds most trafficked mammal (哺乳动物)pangolins.Pangolins are the only mammals that are entirely covered in touch scales(鳞)，which makes them look very strong.But actually they are endangered mammals.There are eight different species of pangolins，four in Asia and four in Africa，and all are threatened with extinction.Although pangolins are protected throughout most of the countries where they live，high demand in East Asia，where the delicious pangolin meat is considered a delicacy and where their scales are used in traditional medicines，is driving an illegal trade in both live animals and pangolin parts.The number of pangolin trafficking is shocking.Experts believe that over the last 10 years more than 1 million pangolins were taken from the wild.It is estimated that between 40，000 and 81，250 pangolins were killed for the illegal trade in 2013 alone.In February，the United States released a plan to deal with wildlife trafficking，which lays out the steps we will take to fight the illegal trade in wildlife，including pangolins.We are strengthening the carrying out of the plan；building international cooperation and contribution to protect wildlife；raising awareness to drive down the demand that is fuelling the illegal trade.Get involved and remember World Wildlife Day (Marcia 3) by spreading the plan.Use social media and tell everyone that now it is time to get serious about wildlife crime and end the demand that threatens species，big and small，from the huge elephant to the shy pangolin.【语篇解读】由于人们的捕猎，一些物种濒临灭绝。本文呼吁人们行动起来，保护濒危物种。1How many endangered creatures are mentioned in the passage?A4.B5.C6.
