问题
When a sleepy driver has trouble with keeping his eyes on the road and gets too close to another car, an alarm sound will warn the driven If nothing is done, the car will automatically come to a stop and in this way prevent an accident. This is a new device which will soon be tested in an experimental car in Japan (33) . The computer warning system keeps track of a driver’s condition by monitoring his heartbeat with signals transmitted from a band around his wrist (35) . The wrist hand records the drivers’ pulse which measures the heartbeat. Each pulse in the wrist sends a signal to the computer. By analyzing the pulse rate, the computer can determine whether a driver is drunk, sleeping or ill. Devices in other parts of the car can also tell the computer if the car is too close to another vehicle or is moving dangerously. The computer will sound the alarm when a problem arises, and will automatically stop the car if the driver ignores the warning (34) .
选项
A、To prevent car accidents.
B、To monitor the driver’s health.
C、To drive the car automatically.
D、To measure the driver’s pulse.
答案
A
解析
题目问为什么试验用的车上装了电脑系统。从短文中可以听到“If nothing is done,the car will automatically come to a stop and in this way prevent an accident(如果没有采取任何措施,车会自动停止,这样可以防止事故发生) ”,从后面可以知道能让车自动停止的正是电脑系统,可见A) 正确。
