17．A recent study，which was published in last week's Journal of the American Medical Association，offers a picture of how dangerous it is to get a lift from a teenage driver．Indeed，a 16-year-old driver with three or more passengers has three times the possibility of a serious accident，compared with a teenager driving alone．
The authors also found that the death rates for teenage drivers increased greatly after 10p．m．，and especially after midnight．With passengers in the car，the driver was even more likely to die in a late-night accident．
Robert Foss，a scientist at the University of North Carolina Highway Safety Research Center，says the higher death rates for teenage drivers have less to do with"really stupid behavior"than with just a lack of driving experience．"The basic issue is that adults who are responsible for giving out licenses fail to recognize how complex and skilled driving is．"he says．
Both he and the author of the study believe that the way to mitigate （使緩解） the problem is to have states set up so-called graduated licensing systems，in which getting a license is a process with several stages．A graduated license requires that a teenager first prove himself able to drive in the presence（在場）of an adult，followed by a period of driving with night of passenger restrictions （限制） before graduating to full driving rights．
Graduated licensing systems have reduced teenage driver crashes，according to recent studies．
33．Which of the following situations is most dangerous according to the passage？B
A．Adults giving a lift to teenagers on the highway after 10p．m．
B．A teenager driving after midnight with passengers in the car．
C．Adults driving with three or more teenage passengers late at night．
D．A teenager getting a lift from a stranger on the highway at midnight．
34．According to Robert Foss，the high death rate of teenage drvers is mainly due toA．
A．their lack of driving experience
B．their frequent driving at night
C．their wrong way of driving
D．their driving with passengers
35．A suggested measure to be taken to reduce teenagers'driving accidents is thatA．
A．the licensing system should be improved
B．they should be forbidden to take on passengers
C．they should not be allowed to drive after 10pm
D．driving in the presence of an adult should be made a rule．
分析 本文主要介紹了青少年司機死亡率高的原因以及解決的方法．研究表明青少年司機的死亡率高與"愚蠢的行為"無關，而與缺乏駕駛經驗有關，緩解這一問題的方法是讓各州建立所謂的分級許可制度，即提高改善駕照的考取制度．
解答 33．B 細節理解題．根據第二段的The authors also found that the death rates forteenage drivers increased greatly after 10 p．m．，and especially after midnight．Withpassengers in the car，the driver was even more likely to die in alate-night accident．可知，研究人員還發現，在晚上10點以后，尤其是午夜過后，青少年司機的死亡率大大增加．在車上有乘客時，司機更可能在深夜事故中死亡．所以在午夜以后車上有乘客時青少年開車更危險，故選B．
34．A 細節理解題．根據第三段的says the higher death rates for teenage drivers haveless to do with"really stupid behavior"than with just a lack ofdriving experience．可知，青少年司機的死亡率高與"真正愚蠢的行為"無關，而與缺乏駕駛經驗有關．所以是由于太缺乏經驗，故選A．
35．A 推理判斷題．根據最后一段的Both he and the author of the study believe that theway to mitigate the problem is to have states set up so-called graduatedlicensing systems，in which getting a license is a process with several stages．可知，他和這項研究的作者都認為，緩解這一問題的方法是讓各州建立所謂的分級許可制度，在這一制度中獲得駕照是一個有幾個階段的過程．所以建議的措施是應該提高改善駕照的考取制度，故選A．
點評 本文是科教類閱讀，考查學生對細節的理解把握和推理判斷能力，做題時一定要找到文章中的原句，和題干進行比較，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，要根據文章事實進行合乎邏輯的推理判斷．
