Hippos (河马) live in Africa (非洲). They’re one of the world’s largest land animals. Here are some interesting information about them.

Plants are very important. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals can get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. So animals and man need plants in order to live. This is why there are so many plants around us.
There are two kinds of plants: flowering plants and non-flowering plants. Almost all the trees around us are flowering plants. You can know some trees from their flowers and fruit. Non-flowering plants do not grow flowers. You can not see many non-flowering plants around you.
If you look carefully at the plants around you, you will find that there are many kinds of plants. Some plants are large and some are small. Most of them are green. Thanks to the plants around us, we can live on the earth.

We sometimes say the lion is “the king of the jungle (丛林)” because it is 1 (strong) than the other animals. It can run 2 (fast) than most other animals and it can hunt best. The lion is the 3 (high) animal in the land food chain (食物链).
Who is at the top of the world’s food chain
People are! We are not the 4 (big) or the fastest, but we are the 5 (clever). We invented cars and now we can move 6 (fast). We could not fight 7 (well) than a lion, so we invented guns. Now we can hunt best.
People’s inventions are 8 (clever), but they can be dangerous, too. For example, many years ago in Inner Mongolia, people used guns to kill a lot of wild wolves (狼).The wild wolves usually eat wild rabbits. But in recent year, the number of wild rabbits is becoming 9 (big and big) because the number of wild wolves is getting 10 (small and small).
Much of the grassland became desert because it was destroyed by the rabbits.
Remember that we are a part of the food chain. If we protect animals, we are protecting ourselves.
