Question

1．When an animal becomes extinct（滅絕），we will never see it again，except for some bones（骨頭） in the ground．How sad!People are cutting down large forests in Europe，Asia and other parts of the world．This destroys homes of many wild animals．For example，some monkeys and apes（猿）eat the fruit and leaves in the tall trees．People cut down all the tall trees，leaving only the short ones．If the monkeys and apes don't have food，they will die．With more and more people on Earth，there is less room for other animals like bears and wolves．
   Some animals are dying off because people hunt（獵殺）them for food．Some people shoot tigers，lions and other animals for fur to make money．They kill elephants for their teeth，and also force some of them to drag（拉）heavy machines to help them cut down trees．Tourists can hurt animals，too．Turtles lay their eggs on beaches in countries such as Greece，but they can't do this when tourists are on the beach．
  Pollution（污染）is another killer．Some factories pour dirty water into rivers，and then many fish get sick and die．And one day，the Arctic （北極） night melt because of global warming（溫室效應）．Then where will polar bears live？
