话题7：自然(Unit4 Earthquakes)

　　假设你叫李华，你从报纸上得知世界上8种熊中有6种面临灭绝的危险，人类活动是造成熊类濒危的主要原因。你决定给世界野生生物基金会(WWF)写信反映这一情况、提出你的建议，并希望基金会采取行动对熊类予以保护。参考词汇：熊类bear species

　　Dear Sir or Madam, 

　　I’ve learned from a newspaper that six of eight bear species in the world are dying out.Scientists say that humans are their biggest threat because some parts of bears are very expensive as medicine.That’s one of the reasons why bears are often killed.In addition, many habitats of bears are being destroyed as a result of human activities, so bears are losing their homes. 

　　To save bears, I think more reserves for bears should be set up so that they can live freely there.Laws should be passed to prevent people from killing bears.   Please give a hand to the endangered bears.They need help to survive. 

　　Yours sincerely, 

　　Li Hua
