27 When we say that Cambridge us a university town, we don’t mean just that it is a town with a university in it. Manchester and Milan have universities, but we don’t call them university towns. A university town is one where there is no clear separation between the university buildings and the rest of the city. The university is not just one part of the town; it is all over the town. The heart of Cambridge has its shops, pubs (小酒馆), marketplace and so on, but most of it is university—colleges, faculties(各系部), libraries, clubs and other places for university staff(教职员工) and students. Students fill the shops, cafes, bands, and churches, making these as well part, of the university.
The town was there first. Two Roman roads crossed there, and there are signs of building before Roman times (earlier than A.D. 43). Cambridge became a center of learning, and the authority(权威) of the head of the university was recognized by the king in 1226.
With about 8,250 undergraduates and over 2,000 postgraduates, the city is a busy place in “full turn” (全体学生在校上课时). Undergraduates are not allowed to keep cars in Cambridge, so nearly all of them use bicycles. Don’t try to drive through Cambridge during the five minutes between lectures. Your bicycle must go through a boiling sea of other bicycles hurrying in all directions. If you are in Cambridge at five minutes to the hour any morning of full term , you know that you are in a university town.
What is the title of the passage?
A Cambridge --- A University Town
B Cambridge ---A Centre of learning
C Cambridge with Many Students
D Cambridge with a Long History
