Giving red packets, or hongbao, during the Spring Festival is a Chinese tradition. Usually, people put money in red envelopes（信封）and give them to their friends and relatives. 1.They think the money inside can bring good luck. Children can always get red packets from their parents, grandparents and other relatives during the Spring Festival. 2.这是他们最幸福的时候。
3.However, the tradition is changing now. At important festivals, people send red packets on WeChat, QQ and Alipay to their family members and friends even if they are far away.
Some people like the electronic red packet because it is fast. Also, it makes people closer to each other. You can send electronic red packets to others no matter how far they are. People don't care how much money you give them. 4.What they care is how much you care about them. What's more, the electronic red packet brings lots of fun to people. People can send it anywhere at any time.
5.我喜欢电子红包。But I think traditional red packets are better. I like to keep the best wishes from my parents and relatives in those red envelopes.

Wild animals are our friends, but many of them are getting fewer and fewer. We should try to protect them. The four animals below are now in danger.
Tibetan Antelopes
Tibetan antelopes（藏羚羊）mainly feed on grass. They are usually found in groups of about 20. They are killed for their wool, which is warm, soft and fine and can be made into expensive clothes. The number of them is dropping year by year. There are less than 75, 000 Tibetan antelopes left in the world.
Golden Monkeys
Golden monkeys are mainly found in Sichuan, Gansu, and Shaanxi provinces. Golden monkeys have golden-orange fur（皮毛）. They move around in the daytime. They feed on fruits and young leaves of bamboos. But people are destroying the environment where they live. Trees and bamboos are disappearing, so golden monkeys have less and less to eat.
Elephants
Elephants are very big and strong. They are bigger than any other animals on land. They have poor eyesight, but very good hearing and smell. They can lift heavy things and break down branches with their trunk（象鼻）. Now, there are very few elephants in the world. The number of them is becoming smaller and smaller because their living areas are used for farming. Also, people hunt them for their tusks.
Wolves
Wolves are not very big. They have grey fur. Wolves have very good eyesight, hearing and smell. They eat animals, insects and snails. They are friendly to each other and never attack（攻击）people. Wolves are in danger, too. They are losing their living areas because people cut down forests. Soon they will have no home or food.
