Question

2．Learning to drive is important to the independence of teenagers，but it is also a great responsibility．Although having a law that keeps 16-year-old drivers from having more than one teenager in the car with them at first seems unfair，there are convincing reasons for this requirement．
The Insurance Institute for Highway Safety reports that teens are four times more likely than older drivers to be involved in an automobile accident．It also reports that 16-and 17-year-old drivers are twice as likely to have an accident if they have two teenage friends in the car and four times as likely to have one if they have three or more teenage friends in the car with them．Fatal （ 致命的） crashes of 16-year-old drivers involve the highest percentage of speeding，driver error，and number of passengers．This information is enough to cause any reasonable person to wonder about the wisdom of allowing new teen drivers to take a carload of friends anywhere，even if the law permits it．
A study at the National Institutes of Health indicates that the part of the human brain that controls judgment and evaluates the consequences of our actions might not be fully formed until the age of 25．Until this study，researchers had placed the age at 18．If this is true，it could explain the reckless （魯莽的） behavior of many teens，behavior that often extends into their twenties．It also could be a strong reason for being cautious about the driving circumstances of young people．
This is not the only study that indicates such caution is necessary．One study at Temple University in Philadelphia examines the results of peer pressure in ris ky driving situations．The study，which uses a driving game，has an individual guide a car through a course，both alone and in the presence of friends．Three different age groups participated in the study：13-16，18-22，and 24 and older．Members of the oldest group showed caution whether driving alone or with friends present，but the two younger groups took more chances when they were with their friend s．Furthermore，because these drivers were accustomed to the noise and distraction of many passengers，they were unable to see their own mistakes．Once again，this is a good indication that a law restricting the number of teenage rs in the car with a young driver is a good idea．

67．What does the author mainly tell us in Paragraph 2？B
    A．Many deaths have occurred because of inexperience and overconfidence．
    B．It's reasonable to severely limit the passenger number of teen drivers．
    C．New teen drivers have to．a(chǎn)sk permission before driving with friends．

68．From the two studies，the author probably suggests thatD．
     A．different age groups have different peer pressure
     B．teenagers often give wrong judgments above passengers'noise
     C．underdeveloped brain makes teens ignore their mistakes
     D．driving circumstances are bound up with the risk of accidents
69．We can infer that the law restriction can probablyA．
     A．protect teens on the highway
     B．raise teens'sense of responsibility
     C．reduce the number of fatal crashes
     D．force teens to drive with caution70．With which statement would thuthor most
70．kely disagree？C

Answer 1

分析 本文圍繞法律限制車內(nèi)青少年的人數(shù)這一論點展開論證，通過對兩個研究的分析原因，論證了法律的可行性，科學(xué)性．該法律的最終結(jié)果就是為了保護(hù)高速路上的青少年．

解答 67．B  細(xì)節(jié)理解題，從第一段there are convincing reasons for this requirement說明緊接第二段將論證法律規(guī)定16歲的年輕司機車內(nèi)不能載超過一個青少年的原因，這樣做是合理的．故選B．
68．D  細(xì)節(jié)理解題，從第二段第一個研究中的結(jié)論It also could be a strong reason for being cautious about the driving circumstances of young people可知駕駛環(huán)境與事故的風(fēng)險有密切聯(lián)系．故選D．
69．A  細(xì)節(jié)理解題，BCD答案均為法律限制車內(nèi)青少年的人數(shù)的直接目的，不是推斷出來的，而A答案則是該法律的最終結(jié)果：保護(hù)高速路上的青少年，文章中并沒提及，但可推斷出來，故選A．
70．C  推理判斷題，文章作者通過兩個研究均表明這條法律的可行性，科學(xué)性，故不會贊同做進(jìn)一步的研究．故選C．

點評 考查學(xué)生的細(xì)節(jié)理解和推理判斷能力．做細(xì)節(jié)理解題時一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確選擇．在做推理判斷題時不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進(jìn)行合乎邏輯的推理判斷．
