Thanks for your listening! 典例 2 Dear Tom, Glad to get your letter. You want to know about wild animals. Let me introduce tigers to you. Tigers are one of the strongest animals in forests.

Their homes are becoming fewer and fewer. Wild animals are our close friends. We should take action to protect them. What animal do you like best? Please write to me soon. Yours, Li Hua 课后练习 练习 1 My Favorite Wild Animal Pandas are the most famous animals in China. They are black and white and look very cute. They are good at climbing trees and their favorite food is bamboo. Lots of people love pandas because they look lovely. But now pandas are in danger. People cut down bamboo forests, so they lose their homes. We should try our best to protect pandas and give them safe living places. They are our precious friends. 练习 2 Dear Anna, I’m glad to tell you about giraffes. Giraffes are the tallest land animals in the world. They have very long necks, so they can eat leaves on tall trees. Most giraffes are gentle. But now their living places are getting smaller. They are facing many difficulties. Wild animals are amazing. We need to protect them and share the earth with them. Can you tell me your favorite animal? I’m looking forward to your reply. Yours, Li Hua $
