    Cambridge (剑桥) is one of the top universities in the world, and it's a city as
well. To the surprise of some visitors, there are no walls around the university.
Classroom buildings, libraries and offices can be seen all over the city. Most of the
members of the city are the students and teachers of thirty-one colleges (学院). It got
its name "Cambridge" from the river called Cam and a bridge built over it. Before the
university was founded 800 years ago, Cambridge was a developing town. It developed faster
because of the opening of the railway and became a city in 1951. Now it has a population
of more than one million. Many young students hope for the chance to study at Cambridge.
