There are some famous buildings in the world. Everyone can recognize (认出) them with their imaginations. For example, when you see a picture of a sports stadium (体育场) that reminds you of a bird's nest, you probably know it is the Olympic Stadium in Beijing.

In fact, other buildings can be recognized more easily. The shape of the building shows the objects people can see inside. In Guizhou, China, people can visit the Meitan Tea Museum, built in the shape of a big teapot. From far away, the teapot- shaped museum looks like some kind of huge work of art. But as one gets closer, the windows make it clear that this is a building.

People who are interested in guitars might want to visit the Guitar Museum in Tennessee, USA. The building is shaped like a guitar. Inside, visitors can see all kinds of guitars and learn about famous guitar players.

One of the newest funny-shaped museums is a pottery (陶器) museum in Korea. This museum, built in 2011, is shaped just like a traditional Korean pot. Along with seeing examples of pots and tools used for making pots in the museum, visitors can try to make their own pots there.

Thousands of years ago, people had to hunt (打猎) for food. They lived in caves (洞穴) and needed fire to keep . Some of them drew pictures on the walls of their caves.

We don't know why they drew the pictures. They had to go  into the cave to do it, so they must have had a plan. They probably took a light them, which was made of animal fat. Maybe they drew the pictures to  good luck when they hunted. Others think the spears (矛) in the pictures mean that they were  other people to hunt.

For paint, they mixed animal fat with some different things like dirt or berries. They used sticks to brush the paint onto the of their caves. Some of the drawings are colorful and others are black from the burned end of a stick.

These people drew what they saw around them  such as tigers, deer, horses, and sometimes birds and fish. They also drew people, but not very .

The pictures are good most of the time. The tigers look strong and powerful. Many of the horses and deer look graceful.

These drawings have been in more than 130 caves- -mostly in England and France. Maybe there are more that we haven't found yet. It's interesting to look at such old drawings.
