If we were asked exactly what we were doing a year ago, we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day, we should be able to give an answer to the question. It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country, but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4 000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to wrtie.

A. it is written down
B. no written account is available
C. it proves to be true
D. people are interested in it

Not only will you learn the subject matter of your choice, but you’ll gain an understanding of the American educational system as well.

Passage One
Years ago our cities were full of cars, buses and trucks. Now the streets are completely congested (拥挤的) and it is very difficult to drive a car along them. Drivers must stop at hundreds of traffic lights. What are our cities going to be like in ten or twenty years Will enormous (巨大的) motorways be built across them With big motorways cutting across them, full of noisy, dirty cars and lorries, our cities are going to be awful places. How can we solve the problem
There are some good ideas to reduce the use of private cars. In 1989, for example, the authorities in Rome began an interesting experiment: passengers on the city buses did not have to pay for their tickets.
In Stockholm there was another experiment: people paid very little for a season ticket to travel on any bus, trolley bus, train or tram in all the city.
