阅读短文，选择正确答案。 Perhaps you have heard a lot about the Internet, but what is it? The Internet is many different networks (网络) around the world. A network is a group of computers put together. These networks joined together are called the Internet. Maybe that doesn't sound interesting. But when we've joined the Internet, there are lots and lots of things we can do. We can have a lot of interest on the World Wide Web(www). We can use the Internet instead of a library to find all kinds of information for our homework. We can find information about our favourite sports or film stars and do shopping on the Internet. We can also send messages to other people by e-mail.
