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.
Sometimes, of course, even if the people cannot write, they may know so
A. kept a written record of every past event
B. not burnt their written records in wars
C. told exact stories of the most important happenings
D. made more songs and dances

Virtual Driver
Driving
involves sharp eyes and keen ears, analyzing with a brain, and coordination
between hands, feet and brain. A man has sharp eyes and keen ears, analyzes
through his brain, and maintains coordination (协调) between his hands and brains.
He can control a fast-moving car with different parts of his body.
1 Apparently there isn’t anyone in the driver’s
cab (驾驶室), but there is in fact a virtual driver. This virtual driver has eyes,
brains, hands and feet too. The minicameras on each side of the car are its eyes
and are responsible for observing the road conditions ahead of it as well as the
traffic to its left and right. If you open the boot (行李箱), you can see the most
important part of the automatic driving system: a built-in computer.
2 The brain of the car is responsible for
calculating the speeds objects surrounding the car are moving at, analyzing
their position on the road, choosing the fight path, and giving orders to the
wheel and the control system.
In comparison with the human
brain, the virtual driver’s best advantage is that it reacts quickly.
3 However, it takes the world’s best racecar
driver at least one second to react, and this doesn’t include the time he needs
to take action.
With its rapid reaction and accurate control,
the virtual driver can reduce the accident rate on expressways considerably. In
this case, is it possible for us to let it drive at any time and in any place
4 With its limited ability to recognize
things, the car can now only travel on expressways.
The
intelligent car determines its direction by the clear lines that mark the lanes
clearly and recognizes vehicles according to their regular shapes.
5 This being the case, people still have high
hopes about driverless cars, and think highly intelligent cars are what the cars
of the future should be like.
A. Experts say that we cannot do
that just yet.
B. In the near future, intelligent cars will be
put into commercial operation.
C. This is the brain of the
car.
D. But how does an intelligent car control
itself
E. It completes the processing of the images sent by
the cameras within 100 milliseconds.
F. However, it cannot
recognize moving people and bicycles on ordinary roads that have no clear
markings on them.
[单项选择]Some of them were well behaved, ______ were insulting.
