A concept car developed by Japanese
company Nissan has a hreathalyzer-like detection system and other instruments
that could help keep drunk or over tired drivers off the road.
The car's sensors(传感器) check odors(气味) inside the car and monitor a driver's
sweat for traces of alcohol. An in-car computer system can issue an alert or
even lock up the ignition(点火) system if the driver seems over-the-limit. The air
odor sensors are fixed firmly and deeply in the driver and passenger seats,
while a detector in the gear-shift knob measures perspiration from the driver's
palm. Other carmakers have developed similar detection systems.
For example, Sweden's Volvo has developed a breathalyzer attached to a car's
seat belt that drivers must blow into before the engine will start.
Nissan's new concept vehicle(交通工具) also includes a dashboard-mounted
camera that tracks drivers' alertness by monitoring their eyes. It will sound an
alarm and issue a spoken warning in Japanese or English if it judges that the
driver needs to pull over and rest. The car technology is still
in development, but general manager Kazuhiro Doi says the combination of
different detection systems should improve the overall effectiveness(效力) of the
technology. "For example, if the gear-shift sensor was bypassed(迂回) by a
passenger using it instead of the driver, the facial recognition system would
still be used," Doi says. Nissan has no specific timetable for marketing the
system, but aims to use technology to cut the number of fatalities involving its
vehicles to half 1995 levels by 2015. The car's seat belt can
also tighten if drowsiness is detected, while an external camera checks that the
car is keeping to its lane properly. However, Doi admits that some of the
technology, such as the alcohol odor sensor, should be improved. "If you drink
one beer, it's going to register, so we need to study what's the appropriate
level for the system to activate," he says. In the UK, some
research groups are using similar advanced techniques to understand driver
behavior and the effectiveness of different road designs.
单选题
Which of the following statements is NOT true of the Japanese concept
car?
A. It has a sensor system that could issue a warning if the driver is
drunk.
B. It has sensors that detect traces of alcohol inside the car.
C. It has sensors locked up in the ignition system.
D. It has a breathalyzer-like detection system.
【正确答案】
C
【答案解析】[解析] 根据文章第二段第二句“An in-car computer system can issue an alert or even lock up the ignition system if the driver seems over-the-limit.”可知，若司机酒精过量，车内的电脑系统可发出警告，甚至可以锁住引擎，所以C项错误。根据第一段a concept car...has a breathalyzer like detection system可知，概念车有类似酒精测量器的装置，所以D项正确。根据第二段第一、二句“The car's sensors check odors inside the car...traces of alcohol. An in-car computer system can issue an alert...”可知传感器可检测车内的酒精含量。酒精超标时，可以对司机发出警告，所以A项和B项正确，故本题选C。

What has Volvo developed?
A. The same detection system mentioned in the previous paragraph.
B. A breathalyzer attached to a car's seat belt.
C. A smart car seat belt.
D. An intelligent engine.
【正确答案】
B
【答案解析】[解析] 根据文章第三段“Other carmakers have developed similar detection systems. For example, Sweden's Volvo has developed a breathalyzer attached to a car's seat belt that drivers must blow into before the engine will start.”可知，沃尔沃公司也发明了一种相类似的酒精检测装置，安装在保险带上，所以B项正确，A项错误。而C项和D项文章都未提及，所以本题选B。

What is the function of the camera mentioned in Paragraph 4?
A. It monitors the driver's eyes to see if he needs a rest.
B. It judges if the driver wants to pull over.
C. It judges if the driver wants to take a rest.
D. It issues an alarm when the driver speaks.
【正确答案】
A
【答案解析】[解析] 根据第四段“...camera that tracks drivers' alertness by monitoring their eyes...sound an alarm and issue a spoken warning...if it judges that the driver needs to...rest”可知，相机跟踪司机的眼睛活动从而监测司机是否保持清醒状态，如果发现司机需要停车休息，便发出警告，所以本题选A。
单选题
According to Doi, ______.
A. the overall effectiveness of the detection technology has improved
B. Nissan is making a timetable to market the detection system
C. it is impossible to improve the overall effectiveness of the detection
system
D. Nissan aims to improve the detection technology to reduce the fatality
rate
【正确答案】
D
【答案解析】[解析] 根据第五段第一句“The car technology is still in development...Doi says the combination of different detection systems should improve the overall effectiveness of the technology.”可知，监测技术仍然在发展之中，使用不同的监测系统能改进这项技术的整体有效性，所以A项和C项都错误。根据本段最后一句“Nissan has no specific timetable for marketing the system, but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015.”可知，日产公司并没有明确将这项技术推向市场的时间，但它试图借助这项技术到2015年将日产车的事故率减少到1995年的一半，所以B项错误，而D项正确，故本题选D。

Which of the following is NOT mentioned in Paragraph 6?
A. An external camera checks that the car is going properly.
B. The car will automatically keep to its lane.
C. The seat belt will tighten when the driver is found drowsy.
D. The technology of the alcohol odor sensor should be improved.
【正确答案】
B
【答案解析】[解析] 根据第六段第一句“The car's seat belt can also tighten if drowsiness is detected, while an external camera checks that the car is Keeping to its lane properly.”可知，若探知司机昏昏欲睡，安全带会收紧，而外部的相机也会检查汽车是否偏离路线，所以A项和C项正确。根据本段第二句“...the alcohol odor sensor, should be improved...”可知，气味传感器有待改进，所以D项正确。而B项文中未提及，故本题选B。
