阅读理解 The Internet is a big place. Nobody has the time to look at every webpage(网页) to find something. Yahoo can help us to find what we need. Two Stanford University students, David Filo and Jerry Yang started Yahoo in 1994. They started by making a list of their favourite webpages. When their list got longer, they made a database(数据库) to keep their information. They let everybody use it for free. Soon, thousands of people began to use their service. They then made a new kind of software. It could take certain information and arrange it for someone to look at. If you search for, say, 'blue whales', the engine will give you a list of webpages with those words. Yahoo became a public company in 1996. Filo and Yang, still young men, became rich. As their company grew, they went on working hard. They improved their software. They also added more services, like shopping, free e-mail, in many different countries and languages.
