    This picture below was taken at the Shengnongjia National Nature Reserve（神农架国家级自然保护区） in Hubei province.You can see hundreds of wooden boxes hanging off a steep cliff（陡峭的悬崖）.These little boxes are all hives（蜂窝）.They are home to the Asian honey bee. （1）Why are the bees being raised 1，200 meters above sea level？ It's a long story.
    Beekeeping is a 2，000-year-old practice in China.Today about half of the world's supply（供应） of honey comes from China.But now，over 80 percent of its native bee population have died out.Their hives have been under attack（袭击） from the European honey bee.（2）在大自然蜜蜂发挥着重要的作用。 In order to protect the rest of the native bee populations，Chinese beekeepers built "walls of hives" in Shennongjia.What makes this area so special for beekeeping？Its land is covered by forest.（3）这儿有一千多种不同种类的植物。 Such an environment can help bees produce better honey.
    The bees are enjoying themselves in their new homes.（4）However，things are completely different for the beekeepers. （5）In order to check on hives and collect honey，they have to climb on top of each of the wooden boxes. The higher ones can only be reached by rope.Not every drop of honey comes easy.
