There are many rare animals and plants in the park. It is   3   only home to Hainan gibbons  (长臂猿). Over 40years ago,  4   the rainforest got smaller and smaller,  there were fewer than 10 gibbons left. That's because   5   can only live in environmentally healthy forests. Thanks   6   the planting policy,  there are 36 of them now. The park is also the world's biggest“medicine store”. About 80 percent of the  plants here can be used as medicine. More   7  , it is a symbol of China's greener future that can be carried on by generation (一代) after generation.

In the past five years,  Hainan   8   great  efforts to improve local situations. However,  I'm still worried about the future of the species in Hainan. I wonder   9   we can do to live together with the animals and plants. I think it's very important for our school   10   a report on this topic.

Thank you.

Yours sincerely,

Zhang Chen
