In many stories, they are brave. The tiger is at the top of the food chain. It helps keep the number of other wild animals in balance. For this reason, tigers are important to the environment.
Tigers are in danger of going extinct. In recent years, tigers have been in danger of disappearing. Some people hunt and kill tigers for money. People have cut down a lot of trees as well.

Read the passage and find the main idea of eachparagraph with the sentences that support the main idea. The panda is one of the animals most in danger. Pandas live in the forests and mountains of Southwest China. They mainly eat 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 fewer and fewer places to live. Pandas don’t have many babies, and baby pandas often die. The situation(情况) is becoming very serious.Our government(政府) is working hard to save pandas. There are more than 30 nature reserves(保护区) to protect pandas in China but these are not enough. The government made a new plan to help pandas. The nature reserves will be bigger and the bamboo will grow better. Then pandas will have enough bamboo to eat and enough places to live. Pandas born in zoos may go back to live in the nature reserves.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(世界自然基金会). The WWF works to protect all animals in danger, so the panda became the symbol of all animals in danger. There is still a long way to save the panda. Think of other animals in danger such as tigers, whales(鲸鱼) and elephants. We need to save the panda, and we need to save other animals too.
