题目内容
15.I passed my driving test at the fourth attempt.You might think that means I'm not as safe as someone who passed for their first attempt.But would you feel safer with no driver at all?Maybe not,and it's for this reason that automotive firms have included driver-assist functions in their prototype(原型) driverless cars.This allows the human driver to take over if there is a problem.Google is one manufacturer that has prototype driverless cars.These cars have been newly equipped with auto-steering wheels and conventional/traditional controls to allow normal driving.But this is just a stage---the vision is to have fully automated cars very soon.The director of Google's self-drive project,Chris Urmson,hopes his 11-year-old son will never have to take a driving test.To achieve that,the cars need to be on the road in five years.He says driverless cars will greatly reduce accidents and traffic jams.
According to Chris,"1.2million people are killed on the roads around the world each year.That number is equal to a jet falling out of the sky every day."He thinks gradual changes to existing car designs are not enough to deal with the problem."If we are really going to make changes to our cities and get rid of parking lots,we need self-drive cars."He says.
Google's prototype driverless cars have covered over a million kilometers on the road.They have also had to deal with unexpected situations,such as a child driving a toy car in the road,and a woman in an electric wheelchair chasing a duck.In each case,the cars reacted safely.
Some are not convinced.Sven Beiker of Stanford University thinks driverless cars will still need human input in extreme circumstances.He also worries that people may forget how to operate their vehicles if they do not do it regularly.I guess I shouldn't throw away my driver's licence just yet.
33.What can be known about driverless cars?B
A.They are fitted with newly-developed steering wheels.
B.They include functions managed by human drivers.
C.They need traditional controls to avoid traffic jams.
D.They will be purchased on the market in five years
34.What's the attitude of Sven Beiker towards driverless cars?B
A.Supportive B.Cautious C.Neutral D.Hopeful
35.What does the passage mainly talk about?D
A.Why we need driverless cars in the near future
B.How to control a driverless car without a driver's licence
C.Differences between driverless cars and conventional ones
D.A brief introduction of driverless cars and some opinions on them.
分析 本文属于说明文阅读,作者通过这篇文章向我们介绍了无人驾驶汽车的简介及作者的几点看法.
解答 33-35BBD
33.B 推理判断题,根据第二段These cars have been newly equipped with auto-steering wheels and conventional/traditional controls to allow normal driving.But this is just a stage---the vision is to have fully automated cars very soon.可知这些车已配备了汽车转向轮和常规/传统控制系统,由此可知无人驾驶汽车包括由人类司机管理的功能,故选B.
34.B 细节理解题,根据最后一段Sven Beiker of Stanford University thinks driverless cars will still need human input in extreme circumstances.He also worries that people may forget how to operate their vehicles if they do not do it regularly.可知Sven Beiker认为无人驾驶汽车将仍然需要人力投入,由此可知他对无人驾驶汽车的态度是谨慎的,故选B.
35.D 主旨大意题,通读全文可知作者通过这篇文章向我们介绍了无人驾驶汽车的简介及作者的几点看法,故选D.
点评 考查学生的细节理解和推理判断能力.做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确选择.在做推理判断题时不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
