The water is brought from the waterworks to each street by a large underground pipe—a water main. The water in this pipe is then forced by pressure into the smaller pipes which carry it to storage tanks at the tops of the buildings. Other pipes bring the water down from the storage tank to the kitchens and bathrooms in the building.
When the water has been used, it is taken away from the building by drainpipe. These take the waste water to another large pipe under the road—the main sewer. The waste water then flows along the sewer to the sewage works where it is cleaned. This "clean" water is then poured into the sea or into a river, or in some countries, sent back to the waterworks to be used again.
Electricity is also brought to the house by a main, in this case a cable. This cable may be underground or, in country districts, it may hang above ground on pylons. The cable is connected to a meter in the building. This meter measures the amount of electricity that is used in the building. Near the meter there is a master switch which can cut off the supply of electricity. There are also fuse boxes between the master switch and the wires which take the electricity to each of the switches in the building. All these wires, fuses and switches are the "wiring circuit".
It can be inferred from this passage that______.

When we say that Cambridge is a university town we do not mean that it is a town with a university in it. 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, restaurants, market place and so on, but most of it is university—colleges, libraries, clubs and other places for university staff and students.
The town was there first. Cambridge became a center of learning in the thirteenth century. Many students were too poor to afford lodgings. Colleges were opened so that students could live cheaply. This was the beginning of the present day college system.
Today there are nearly thirty colleges. Very few students can now live in college for the whole of their course; the numbers are too great. Many of them live in lodgings at first and move into college for their final year. But every student is a member of his college from the beginning. He must eat a number of meals in the college hall each week.
Students 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, as you will find crowds of people on bicycles hurrying in all directions. If you are in Cambridge at five minutes to the hour any morning of the term, you' 11 know that you are in a university town. Stop in some safe place, and wait.
