Children are playing on the grass.Their mothers and fathers are eating food and watching them.Is this a family having a picnic（野餐） in the park？No，it's a group of Mountain Gorillas（大猩猩） in a forest in Africa.
Gorillas live in groups in the forest.Mountain Gorillas live in forests in the mountains.Mountain Gorillas are the biggest kind of gorilla.They have long hair that keeps them warm in the cold mountains.
Mountain Gorillas eat plants and they eat them most of the day.They get up early in the morning and start eating.When it is very hot，the gorillas sleep a little，and then they get up and eat till it gets dark.Some Mountain Gorillas eat 18 k g plants in one day!At the end of the day，the gorillas make a nest to sleep in.They sleep on the grass or in the trees.
The forests are the Mountain Gorillas' home and food，but people are cutting down the forests.Many Mountain Gorillas lose their homes and even lives when people cut down forests.
There are only about 500 Mountain Gorillas in the world today.Twenty years ago there were about 15，000 Mountain Gorillas.
We must do something to save the forests，so we can save the gorillas.
