Last summer, I took an exciting trip to Nairobi National Park. It’s just 7 kilometers away from the city center. What makes the park special? ____1____ As soon as I arrived there, the warm African sun kissed my face, and the loud roar (咆哮) of a lion reached my ears. I couldn’t wait to start.

The park is huge, covering about 117 square kilometers. Electric fences (围墙) keep the park separate from the city on three sides-east, west, and north. But the south side keeps open, letting animals move freely as the seasons change. The park has been there for over 70 years. There are 80 kinds of mammals (哺乳动物) and more than 500 kinds of birds in the park. ____2____ But here’s an important rule—they must stay inside their cars. Why? Because there are big, dangerous animals like lions and leopards walking around!

It’s unbelievable that we can not see elephants in the park. ____3____ So there might not be enough food for the other animals. Also, they could be a danger to people living nearby. However, in the park, there is a meaningful Ivory Burning Monument (象牙焚烧纪念碑). It’s said that Kenya’s president burned 2.5 tons of ivory here to show the government’s strong will against ivory trade in 1989. And the monument was built to remind people of this famous historical event. Today many visitors from all over the world and Kenyan students go there.

____4____ And we all share the same home—the earth. We should care for our animal friends and protect our planet.

A. One reason is that elephants eat tons of plants for food.

B. It’s the only wildlife park inside a capital city around the world!

C. Every year, millions of visitors come to see these wonderful animals.

D. Many visitors can walk anywhere in the park to see the animals freely.

E. After this experience of travelling, I know humans and animals are friends.
