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 (使減少到最低限度) 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 (與前車距離過近) 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 (油門).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.

分析 本文是一篇科教類閱讀,主要講了作者是一位車迷,但是鑒于目前車子的改變不大,作者構(gòu)想了未來的車子是什么樣的.
解答 28-32BCADB
28題答案:B考查細(xì)節(jié)推理,根據(jù)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.我對汽車著迷,尤其是因為我大哥哥是個汽車迷而且訂閱了諸如Car and Driver 和 Motor Trend這樣炫酷的雜志.可知本題答案為B選項.
29題答案:C考查細(xì)節(jié)推理,根據(jù)前面一句的They featured unconventional styling and things like small nuclear reactors as power sources.他們的特征是非常規(guī)風(fēng)格而且還有還有作為能源的核反應(yīng)堆.可知后面的"然而,我的車子并不能做任何一件我哥哥的車子不能做的事情"意思是"到現(xiàn)在為止車子的表現(xiàn)還沒有什么改變";故本題答案為C.
30題答案:A考查細(xì)節(jié)推理,根據(jù)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.(事實上,考慮到最近一些關(guān)于人們偶爾被低速行駛碰撞中的氣囊殺死的新聞,它們很明顯還需要一些改進(jìn)).可知本題答案為A選項.
31題答案:D考查細(xì)節(jié)推理,根據(jù)倒數(shù)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…(汽車能裝備感測器--這種感測器能夠探測出駕駛系統(tǒng)中的酒精并且會阻止車子被啟動).可知本題答案為D選項.
32題答案:B考查細(xì)節(jié)推理,根據(jù)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…(車子最終會自動駕駛嗎?沒有理由不相信在技術(shù)上是可能的…)可知"未來車子自動駕駛是可能的",故本題答案為B選項.
點(diǎn)評 本文是一篇科教類閱讀,題目涉及多道細(xì)節(jié)理解題,做題時結(jié)合原文和題目有針對 性找出相關(guān)語句進(jìn)行仔細(xì)分析,結(jié)合選項選出正確答案.推理判斷也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確的答案.
