Passage One
There was a nasty (肮脏的，卑鄙的) accident in our town not long ago, and I saw it happen. I was standing near a road which was under repair, not doing anything special—just watching the men at work. It was not far from the new motorway (高速公路) that runs past the town. It was an old road that used to be very busy—and dangerous before the motorway was built. Today, most cars use the new "superhighway" and the old road is pretty quiet, although cars do often come off the motorway into the town faster than they should.
Anyway, the men were repairing part of the road and there were signs up for at least 200 meters, telling everybody that the road was narrower than usual. Most of the drivers in both directions saw the signs and slowed down.
Then three cars came along close together, the third one moving at a very high speed. The first one pas sed the workmen and wanted to turn left. Meanwhile the third car came flying past the second one. The sec and car stopped. I think the driver knew something was going to happen. It did. The third car had no chance of stopping. Its driver braked (刹车) and pulled over to miss the first car and went right off the road.
There were four people in that car: a man, two women and a child. The child was a boy of nine. I read later that they were going shopping—just shopping, nothing more important than that. The driver was badly hurt. The little bay was hurt too. Both the women were killed immediately. One of them was the driver’s wife and the other was the mother of the little boy. They never got to the shops.
A:the driver of the first car B:the driver of the second car C:the driver of the third car D:both B and C

Keeps Watch for Drunk Drivers{{/B}} ? ?A concept car developed by Japanese Company Nissan has a breathalyzer-like detection system and other instruments that could help keep drunk or over-tired drivers off the road. ? ?The car’s sensors check odors inside the car and monitor a driver’s sweat for traces of alcohol. An in-car computer system can issue an alert or even leek up the ignition system if the driver seems over-the-limit. The air odor sensors are fixed firmly and deeply in the driver and passenger seats, while a detector in the gear-shift knob measures perspiration from the driver’s palm. ? ?Other carmakers have developed similar detection systems. For example, Sweden’s Volvo has developed a breathalyzer attached to a car’s seat belt that drivers must blow into before the engine will start. ? ?Nissan’s new concept vehicle also includes a dashboard-mounted camera that tracks a drivers alertness by monitoring theft eyes. It will sound an alarm and issue a spoken warning in Japanese or English if it judges that the driver needs to pull over and rest. ? ?The car technology is still in development, but general manager Kazuhiro Doi says the combination of different detection systems should improve the overall effectiveness of the technology. "For example, if the gear-shift sensor was bypassed by a passenger using it instead of the driver, the facial recognition system would still be used," Doi says. Nissan has no specific timetable for marketing the system, but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015. ? ?The car’s seat belt can also tighten if drowsiness is detected, while an external camera checks that the car is keeping to its lane properly. However, Doi admits that some of the technology, such as the alcohol odor sensor, should be improved. "If you drink one beer, it’s going to register, so we need to study what’s the appropriate level for the system to activate," he says. ? ?In the UK, some research groups are using similar advanced techniques to understand driver behavior and the effectiveness of different road designs. |
A:It monitors the driver’s eyes to see if he needs a rest. B:It judges if the driver wants to pull over. C:It judges if the driver wants to take a rest. D:It issues an alarm when the driver speaks.

Riding{{/B}} ? ?In a moment of personal crisis, how much help can you expect from a New York taxi driver? I began studying this question after watching the "Taxicab Confessions," a series of documentaries in which hidden cameras record the secrets of unsuspecting taxi riders. I found the results varied. ? ?One morning I got into three different taxis and announced: "Well, it’s my first day back in New York in seven years. I’ve been in prison." Not a single driver replied, so I tried again. "Yeah, I shot a man in Reno," I explained, hoping the driver would ask me why, so I could say casually, "Just to watch him die." But nobody asked. The only response came from a Ghanaian driver:" Reno? That is in Nevada?" ? ?Taxi drivers were uniformly sympathetic when I said I’d just been fired. "This is America," a Haitian driver said. "One door is closed. Another is open." He argued against my plan to bum down my boss’s house: "If you do something silly and they put you away, you cannot look for another job." A Pakistani driver even turned down a chance to profit from my loss of hope: he refused to take me to the middle of the George Washington Bridge, a $20 trip. "Why you want to go there? Go home and relax. Don’t worry. Take a new job." ? ?One very hot weekday in July, while wearing a red ski mask and holding a stuffed pillowcase with the word "BANK" on it, I tried hailing a taxi five times outside different banks. The driver picked me up every time. My ride with Guy-Caaude Thevenain, a Haitian driver, was typical of the superb assistance I received. ? ?"Is anyone following us?" ? ?"No," said the driver, looking in his rearview mirror at traffic and me. ? ?"Let’s go across the park," I said. "I just robbed the bank there, I got $25,000." ? ?"$25,000?" he asked. ? ?"Yeah, you think it was wrong to take it?" ? ?"No, man. I work 8 hours and I don’t make almost $70. If I can do that, I do it too." ? ?As we approached 86th and Lexington, I pointed to the Chemical Bank. ? ?"Hey, there’s another bank," I said, "could you wait here a minute while I go inside?" ? ?"No, I can’t wait. Pay me now." His reluctance may have had something to do with money—taxi drivers think the rate for waiting time is too low—but I think he wanted me to learn that even a bank robber can’t expect unconditional support. |
A:The driver thought that the rate for waiting time was too low. B:The driver thought it wrong to support a taxi rider unconditionally. C:The driver was frightened and wanted to leave him as soon as possible. D:The driver wanted to go home and relax.
