For this reason, tigers are important to the environment.Paragraph2 Tigers are in danger of going extinct. In recent years, tigers have been in danger of disappearing.

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 dont have many babies, and baby pandas often die. The situation(情况) is becoming very serious.Paragraph1 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.Paragraph2 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.Paragraph3 Language points世纪的表达：世纪的表达：century的复数为centuries。当表示第几世纪，要用序数词前加定冠词the*This book was written _ (century) ago。The telephone was invented in _(a/an/the)19th century.centuriesthethe number of 和和a number of的区别的区别the number of表示.的数量后接可数名词的复数形式，作主语时，谓语动词用单数。The number of the students in our school _ (be) about 3500.a number of为许多、大量，作主语时，谓语动词用复数。A number of students _(be) playing in the playground.isareIt helps keep the number of other wild animals in balance. 它可以帮助保持其它可以帮助保持其他野生动物的数量平衡。他野生动物的数量平衡。 balance 在句中用作名词，意为在句中用作名词，意为“平衡；均衡平衡；均衡”，常用短语，常用短语be out of balance，意，意为为“不平衡不平衡”；keep in balance意为意为“保持平衡保持平衡”；balance还作动词，表示还作动词，表示“（使）（使）平衡；（使）均衡平衡；（使）均衡”。如：。如： You must learn to keep your balance in skating. 在滑冰时你必须要学会保持平衡。在滑冰时你必须要学会保持平衡。 in danger（ of） 处于处于()危险之中，危险之中，of后后 接名词接名词 或或V-ingEg: The sick man is in danger of death. 这个病人有死亡的危险。 n.
