1、大学英语六级模拟试卷 536及答案与解析 一、 Part I Writing (30 minutes) 1 For this part, you are allowed 30 minutes to write a short essay entitled Campus Safety. You should write at least 150 words following the outline given below. 1校园安全十分重要 2因此,学校应当 3我们自己应当 Campus Safety 二、 Part II Reading Comprehension (Skimming an
2、d Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-4, mark: Y (for YES) if the statement agrees with the information given in the passage; N (for NO) if the statement contradicts
3、 the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Networked Automobile Im driving through eastern France, the blip-blip of the lane markers running backward through my peripheral (边缘的 ) vision at about 90mph. I check the mirrors: nothing ther
4、e. Pretending to doze off, I let the car drift gently to the left. Just as it begins to change its direction towards the dotted line, the left side of my seat vibrates, activated by an infrared (红外线的 ) sensor looking at the road paint. I can assure you that the buzzing seat would have jolted (摇晃 ) m
5、e back to the job at hand. The car Im driving is a prototype from the French automaker Peugeot Citroen, but a showroom-ready copy isnt many months away. Flash back five months: Im at a test track at the base of Mount Fuji in Japan, in a Lexus fitted with a pre-crash safety system. I drive down the t
6、rack at about 40mph toward a rubber post. Instinct and education make it hard to keep my foot off the brake, but a group of earnest engineers insist that I aim their $70,000 sedan straight for the post. At the last fraction of a second, when the cars radar sensors and microprocessors have determined
7、 that the idiot at the wheel really isnt going to steer around the obstacle, the safety system shoots into action. Seatbelt pretensioners cinch up (系紧 ), and the front and rear suspension dampers stiffen. As soon as I touch the brake pedal better late than never the cars brake-assist tugs them on at
8、 max effort. It isnt enough to avoid the crash, but the impact speed is about half what it would have been without the new system. The next generation of environment-sensing cars will use more than just radar and infrared sensors to watch for signs of trouble. Video cameras will look for stoplights
9、that have turned red and for children who are running toward the road. Distance-sensing lasers will check for vehicles in the drivers blind spot and the passing lane. These sensors wont do anything that a vigilant (警醒的 ) driver cant already do, but what if they could? What if your car could sense ro
10、ad conditions and traffic problems that are out of your sight? Thats coming too. The next giant leap in sensing will be radio-networking that enables cars to exchange information. “Communication (between cars) will be like an additional sensor,“ says Ralf Herrtwich, director of vehicle IT research a
11、t DaimlerChrysler Car-to-car communication will ensure that your automobiles ahead. And this extra “sensor“ will have almost unlimited range, because information can be instantaneously relayed from one vehicle to the next, to the next, and so on. No one doubts the extent of information-gathering and
12、 communication features that will be built into the networked cars of the future. Some of these features will merely assist the driver by, for example, pointing out a patch of black ice around the next bend. But what about the driver who fails to act on the warning? Should his car be empowered to “t
13、ake the wheel“? Some automotive experts foresee a day when our cars will be so well-informed that well be better off leaving some of the driving to them. Time for another demonstration. Its Berlin, and Im in a Smart car, DaimlerChryslers tiny two-seater that has become a familiar in Europes cramped
14、city streets. But this Smart is different: its smart. On the dashboard, a flashing display warns me of an accident two streets away, and the navigation system suggests a detour (绕道 ). My car, outfitted with a GPS position finder and an off-the-shelf wireless local area network (WLAN) communication s
15、ystem, was informed by another car carrying the same gear. If knowledge is power, then the intellectual-horsepower rating of tomorrows vehicles is going to be high. Say just one cars stability-control system is activated at an unusually slow speed on a highway off-ramp (驶出坡道 )- It will send out a sl
16、ippery-road warning. All WLAN-equipped cars in the vicinity then get the message, but they will warn their drivers only if they are headed for the same off-ramp. The system will also provide traffic information on a need-to-know basis. Imagine there is a truck unloading in the next street on your ro
17、ute. It would never make the radio reports, but you could be trapped fuming for 10 minutes. WLAN “traffic radar“, as Herrtwich puts it will let you know and reroute you. What is really new here is the way traffic will behave almost biologically, like a swarm of bees, a self-educating network. This i
18、s a killer apparatus, because it doesnt require expensive infrastructure. No traffic-control center or information exchange. No need for roadside beacons (指向标 ) that the authorities would have to install. Instead cars will seamlessly (无线地 ) set up special networks, passing information from car to ca
19、r. Virtually all of the necessary hardware is already on the shelf at companies such as Bosch, Delphi and Samsung. What is needed now is the software to tie everything together: sensors, wireless radio networks and GPS navigation systems. Together these technologies create a system that provides imm
20、ediate warnings of delays, accidents, temporary speed restrictions and road conditions the everyday hazards that lie in wait just around the corner. And because the system knows exactly where each driver is, it wont drown drivers in a running commentary about what is happening on the other side of t
21、own (unless the other side of town is the destination they have programmed into their navigations systems). Of course, the system will not work well if there arent enough vehicles outfitted with the gear. The question is how to reach critical mass. Fortunately, WLAN networks are good for more than j
22、ust traffic radar; they are also useful for downloading entertainment. “Ten years from now, we are talking about a radically changed way of listening to music, watching TV and videos,“ Herrtwich says. Once WLAN is adopted for in-car entertainment, the technology could also be used for road-safety an
23、d traffic-networking functions. But dont hold your breath. Technical standards are still a few years away Herrtwich predicts 2008. If the first networked cars roll out in 2010, such features will not be standard for at least another decade. 2 What is the author doing in eastern France? ( A) He is ru
24、nning a prototype car in road test. ( B) He is testing the infrared sensor of a prototype car. ( C) He is testing the vibration function of the seat. ( D) He is a model doing propaganda for Peugeot Citroen. 3 What is the function of the pre-crash safety system in Lexus? ( A) Stopping the car before
