Ⅵ.閱讀理解

• 28．Many of the Earth's creatures die because of humans' choices.These choices have nothing to do with food or shelter or anything else that helps humans survive.What kills millions of animals all over the world is that humans want to make money by doing so.
     People use parts of animals for everything from hats to handbags，from jewelry to ashtrays and to make powders that supposedly improve a person's life.Deciding that a species is endangered and protecting it by law are not always enough.People who kill wildlife illegally rarely get caught.
     During the late 1980s，saving elephants became a popular cause.Wildlife protection groups made sure everyone saw pictures or films of elephants with their faces cut off for their ivory.These groups also proved that certain populations of elephants were decreasing.As a result，most people stopped buying objects made of ivory.Laws against poaching （偷獵）were made stronger.Many countries made importing ivory illegal.Killing elephants for their ivory became more risky and less profitable （有利可圖的）．
     However，concern for certain species will become weak after a while.In the late 1970s，people protested （抗議） against the killing of seal babies.Everyone was shocked to see young seals being killed in their icy habitat.The cruel activity stopped.But ten years later，the number of seal babies killed was higher than ever.
     Other animal protection movements have come and gone，such as saving the whales and protecting dolphins.The whale population appears to have increased for now.And the laws are finally changed in America to protect the dolphins that swim with tuna fish in parts of the Pacific Ocean.
     In the years to come，people's attention will probably turn to some other endangered species.Plenty of them urgently need attention. During this time，will the elephants be forgotten？
  
  （1）What leads to the disappearance of millions of wild animals？

  
  A．The growing human population.
  B．Humans' hope for making a fortune.
  C．Humans' too much need for wild food.
  D．Not having enough laws on wildlife protection.
  （2）What can you infer from the text about what happened in the late 1980s？

  
  A．Wildlife protection groups did make great efforts.
  B．Importing ivory in all countries is illegal.
  C．Those who killed elephants all got caught.
  D．Hunting was completely not allowed.
  （3）Why are seal babies mentioned in Paragraph 4？

  
  A．To show the effort to protect seal babies.
  B．To show an increasing number of seal babies.
  C．To show the decrease of worry about certain species.
  D．To show people's protest against the killing of seal babies.
  （4）What does the author mean by using the underlined sentence？

  
  A．Humans should choose some rare animals to protect.
  B．Attention must be paid to saving some endangered wildlife.
  C．Success has been achieved in quite a few cases of wildlife protection.
  D．Concern and movements for animal protection should be always kept.
