    It is very 3 for people to tell male and female lions from each other. You can judge (判断) simply by their appearance. A male lion has mane while female lions do not have. Male lion 4 than female lions. A male lion usually weighs about 200 kilograms which is always heavier than a female lion. Both male and female lions have very 5 mouths. They can break the backs of other animals 6. Lions feed on other animals and one lion usually kills between ten and twenty large animals each year for 7 .

    Lately, people have entered the forests where chimpanzees (黑猩猩) live. The chimpanzees have been getting sick because of people's diseases. In addition, people are hunting chimpanzees. Their number is becoming smaller and smaller.

Chimpanzees live in the plains and forests of Africa. They eat many kinds of food, from plant leaves and seeds to insects and even other small animals. Chimpanzees' favourite food is fruit.

    Chimpanzees are very clever and they can use tools well. They can catch bugs using sticks, and break nuts using rocks.

    The world's forests are much smaller than they were before. Roads were built in deep forests, so people start to enter forests where chimpanzees live. That may lead to many problems. One problem for chimpanzees is that they can easily catch people's diseases and die. Chimpanzees are much closer to people than monkeys.

As it's easier for people to enter forests, they hunt more often. Young chimpanzees are caught to be pets or for scientific researches. The young ones are taken away from the forests, and the adults are killed. Chimpanzees are likely to disappear in the future.
