     I first saw the baby panda when she was only 10 days old. She looked like a white mouse.
We   1   her Xi Wang. It means "hope".      When Xi Wang was born, she was just 100 grams(克).
Xi Wang drank her mother's milk for as  2   as 14 hours a day. When she was six months old,
she started to eat bamboo shoots(嫩芽). Eight months  3  , she was not a small baby any more.
She grew into a   4   young panda and weighed 35 kilos. When Xi Wang was 20 months old,
she had to look after herself because her mother had another baby. Xi Wang has to live by itself.
   5   , it is very difficult for pandas to live in the wild. Here are some problems that pandas like
Xi Wang may have in the future.       If hunters (猎人)  catch a panda,  they will    6    it for its
fur(皮毛).  If farmers    7     trees and forests, pandas will have no place _8   .      
When Mothers leave baby pandas    9   , people will often take them away.  People think that
the baby pandas need help.

will be no pandas in the world.
