Which animal do you think is "the king of the animals", the elephant, the lion or the tiger? They are all
large and strong. But I think the tiger is "the king of the animals". If you watch carefully, you can find some
black lines on the tiger's forehead (前额). The lines look like the Chinese word "WANG". The word
means "the king of the world" in Chinese.
Most of the tigers come from China and India. Tigers are dangerous animals. They look scary (吓人
的). They like eating meat. They have yellow fur with black lines. They usually weigh about 200 to 300kg.
Tigers can run fast. They run at a speed of 20 meters per second.
Some people think they are dangerous. But they don't know tigers are in danger now. There are only
20 to 30 wild South China Tigers in China and less than 300 in the world. Lots of people kill them for
their fur. We should take action to protect them.
