In most states, you have to be at least sixteen years old to start learning to drive. Anyone younger than that who sits behind the wheel of a moving car is violating the law, even ff he or she is closely supervised. Age sixteen is also the minimum age in most states for taking driver's education courses in schools.
Driver's education courses begin with classroom instruction on the rules of the road and traffic laws. You learn, for example, how fast it is safe to go in certain areas, what to do ff a fire engine is near, and what the different road signs mean, When you finish the classroom course, you can apply for a Learner's Permit. In some states you have to take a test before you receive the permit.
When you have your Learner's Permit, you are allowed to drive a car under supervision. This means that you can drive only when you are accompanied by a licensed driver. It is during this period that you actually learn to drive. You learn to steer the car, to start it, to pass other cars, to park and all the other practical things you will need to know.
Your Learner's Permit is good for only a limited amount of time, since it is expected that you will be ready to take the test for your license after a relatively short period of instruction.

More than 60 people died in this earthquake. By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25,000 victims.
Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a.m. on a holiday, when traffic was light on the city's highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes.
Despite the good news, civil engineers aren't resting on their successes. Pinned to their drawing boards are blueprints (蓝图) for improved quake-resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place.
In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports. Called smart buildings, the structures respond like living organisms to an earthquake's vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction.
The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.
One reason why the loss of lives in the Los Angeles earthquake was comparatively low is that ______.
A．new computers had been installed in the buildings
B．it occurred in the residential areas rather than on the highways
C．large numbers of Los Angeles residents had gone for a holiday
D．improvements had been made in the constructions of buildings and highways
