17．Like many other small boys，I was fascinated by cars，not least because my oldest brother was a bit of a car guy and subscribed to cool magazines like Car and Driver and Motor Trend．Every so often，one of those magazines would run an article on the"Car of the Future"．They featured unconventional styling and things like small nuclear reactors as power sources．Yet，frankly，my car doesn't do anything that my brother's Studebaker didn't do．It goes，it stops，it burns gasoline，it plays music．I still have to steer it，and it still runs into things if I don't steer it carefully．
But guess what？All of these things are subject to change in the not-so-distant future．It will still go and stop，but it may not burn gasoline，I may not have to steer it，and it may be a lot better at not running into things．
Airbags aren't the be-all and end-all in safety．In fact，considering the recent news about people occasionally being killed by their airbags in low-speed collisions （碰撞），they obviously still need some development．But they aren't going away，and in fact，you can expect to see cars appearing with additional，side-impact airbags，something some European car manufacturers already offer．
Better than systems to minimize （使减少到最低限度） injury in the event of an accident，however，are systems that minimize the likelihood of an accident happening in the first place．Future cars may be able to eliminate many of the major causes of accidents，including drunk-driving，tailgating （与前车距离过近） and sleepiness．Cars could be equipped with sensors that can detect alcohol in a driver's system and prevent the car from being started，for example．Many accidents are caused by people following the car in front too closely．As early as next year，you'll be able to buy cars with radar-equipped control systems．If the radar determines you're closing too quickly with the car in front，it will ease up on the throttle （油门）．For city streets，expect other radar devices that will give advance warning that the car in front of you has slowed abruptly （突然地） and you should step on the brakes-or that may even brake for you．
Will cars eventually be able to drive themselves？There's no reason to think it won't be technically possible，and Mercedes is working on a system that can brake，accelerate and steer a vehicle down a highway on its own．Nobody really expects people to give up all control to their cars，but such systems could be used as failsafe systems to keep cars on the road and bring them safely to a stop even if the driver suddenly became disabled．

解答 28-32BCADB
28题答案：B考查细节推理，根据文章第一段的I was fascinated by cars，not least because my oldest brother was a bit of a car guy and subscribed to cool magazines like Car and Driver and Motor Trend．我对汽车着迷，尤其是因为我大哥哥是个汽车迷而且订阅了诸如Car and Driver 和 Motor Trend这样炫酷的杂志．可知本题答案为B选项．
29题答案：C考查细节推理，根据前面一句的They featured unconventional styling and things like small nuclear reactors as power sources．他们的特征是非常规风格而且还有还有作为能源的核反应堆．可知后面的"然而，我的车子并不能做任何一件我哥哥的车子不能做的事情"意思是"到现在为止车子的表现还没有什么改变"；故本题答案为C．
30题答案：A考查细节推理，根据文章第三段的In fact，considering the recent news about people occasionally being killed by their airbags in low-speed collisions （碰撞），they obviously still need some development．（事实上，考虑到最近一些关于人们偶尔被低速行驶碰撞中的气囊杀死的新闻，它们很明显还需要一些改进）．可知本题答案为A选项．
31题答案：D考查细节推理，根据倒数第二段的Cars could be equipped with sensors that can detect alcohol in a driver's system and prevent the car from being started…（汽车能装备感测器--这种感测器能够探测出驾驶系统中的酒精并且会阻止车子被启动）．可知本题答案为D选项．
32题答案：B考查细节推理，根据文章最后一段的Will cars eventually be able to drive themselves？There's no reason to think it won't be technically possible…（车子最终会自动驾驶吗？没有理由不相信在技术上是可能的…）可知"未来车子自动驾驶是可能的"，故本题答案为B选项．
