Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks(网络) didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system(系统) had to be set up. It should be good enough to be used by many different computers.

However, computers were still expensive and the Internet was difficult to use. By the start of the 1990s, computers become cheaper and easier to use.

Every year, many people travel to Tanzania（坦桑尼亚）to see the animals there. But do you know how they travel around?

The most common way is traveling by bus, but when people get on a bus in Tanzania, they’ll find it's different from the buses we often use. The windows are so small that the bus looks like a cage. This kind of bus is safe when people go to see dangerous animals and take pictures.
