Read with him and answer the questions below.Zhang Nature Reserve is in Heilongjiang Province in the north-east of China. It is one of the world’s most important wetlands. The area provides food and cover for a lot of wildlife. It is home to some rare birds. For example, about 40% of red-crowned cranes live in Zhalong.Many birds live in Zhalong all year round, while some go there only for a short stay. Most birds are active in the daytime, so you can easily watch them there.Some people want to make the wetlands smaller in order to have more space for farms and buildings. This will lead to less space for wildlife. Moreover, if fishermen keep fishing there, the birds will not have enough food to eat. Now the Chinese government has made laws to prevent all these things in Zhalong.1 Why is Zhalong an important place for the birds?Because it provides food and cover for them. It’s also home to some rare birds and a lot of wild life. Many birds live there all year round. 2 What other actions can we take to help protect wetlands?We can plant more trees around the wetlands. We can also educate more people about the importance of wetlands and ask them not to litter there.（答案不唯一）思考：What other nature reserves do you know?I know the Wolong Nature Reserve in Sichuan. It’s famous for protecting pandas. I also know the Changbai Mountain Nature Reserve in Jilin. There are many rare plants and animals there.（答案不唯一）Daniel is listening to a talk about a wetland.
