Suppose every person on Earth ate only one kind of food . And one year that food disappeared .

46   that happened , all humans would soon disappear too .

Luckily humans   47   face the problem . However , another creature may . The animal is the giant panda (大熊猫), one of the world’s most   48   animals .

It has been discovered that the bamboo plants the giant pandas eat are dying . As a result , many of the pandas are dying of   49   . In the wild , the giant panda eats only two kinds of bamboo plants . One is the umbrella bamboo ,  50    is the fountain bamboo (喷泉竹). 51     

kinds can live 100years . In its hundred year the bamboo plant blooms ,has seeds and dies .

Last year the umbrella and the fountain bamboo  52    grow in China became 100 years

53   .The plant grows from seeds formed in the late 1870’s . Now almost all of these bamboo plants are dead . Young shoots now grow from the seeds . However , it will be many months   54   the shoots are large   55   to be used as food by the pandas . So the large black and white animals continue  56    .

Can the wild pandas be   57   ? A group of American scientists went to China  58    the pandas in their native habitat (居住地).The studies took place in the areas of Sichuan province in Central China . The scientists especially wanted to find out more about the animals’ food . They wanted to see   59   the pandas are able to change to other foods   60   the two kinds of bamboo are growing .
