阅读下面短文，根据短文内容回答下面问题。
     1. The panda is one of the animals most in danger. There are about 1000 pandas living in nature reserves
today. Zoos and research centers look after about 160 pandas. Scientists are studying how they live and more
baby pandas are born in the zoos.
     2. Pandas live in the forests and mountains of Southwest China. They mainly live on bamboo, and each
panda needs to eat a lot of bamboo every day. The area of bamboo is becoming smaller for many different
reasons, so pandas have less and less land to live on. Pandas don't have many babies, and baby pandas often
die. The situation is becoming very serious.
     3. Our government is working hard to save pandas. There are more than 30 nature reserves to protect
pandas but these ate not enough. The government has made new plans to help pandas. The nature reserves
will be bigger and the bamboo will grow better. Then the pandas will have enough food to eat and enough
places to live in. Pandas born in the zoos may go back to live in the nature reserves.
     4. Most people love pandas. The panda is one of the best-known animals in the world. It is the symbol
for the World Wide Fund for nature. The WWF woks to protect all animals in danger, so the panda has become
the symbol of all animals in danger. There is still a long way to go to save the panda. Think of other animals
in danger such as tigers, whales and elephants-we need to save the panda, and we need to save them,too.
