    When the driver gets sleepy while driving, Driver Alert . A. moves more regularly B. stops working properly C. opens the window for the driver D. sounds more frequently and loudly 05浙江D Supermarkets are trying out new computers that make shopping carts more intelligent . They will help shoppers find cups or toilet soap, and keep a record of the bill. The touch-screen devices are on show at the Food Marketing Institute's exhibition here this week. "These devices are able to create value and get you around the store quicker," said Michael Alexandor, manager of Springboard Retail Networks Inc., which makes a smart cart computer called the Concierge. Canadian stores will test the Concierge in July. A similar device, IBM's "shopping buddy," has recently been test-marketed at Stop & Shop stores in Massachusetts. Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf. "The whole model is driven by advertisers' need to get in front of shoppers," said Alexandor. "They're not watching 30-second TV ads anymore." People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system that will organize the trip around the store. If you're looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them. The devices also keep a record of what you buy. When you're finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay. The new computerized shopping assistants don't come cheap. The Buddy devices will cost the average store about $160,000, and the Concierge will cost stores about $500 for each device. 【查看更多】

     

    题目列表(包括答案和解析)

           A device that stops drivers form falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.

           The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.

           Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.

           Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.

           In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.

           The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.

    According to the text, Driver Alert ______.

    A. aims to reduce tiredness-related accidents

    B. has gone through testing at laboratories

    C. aims to prevent drivers form sleeping

    D. has been on sale for 12 months

    73.   How should a driver respond to the sounds from Driver Alert?

           A. By sounding a warning.                                B. By touching the wristband.

    C. By checking the driving time.                        D. By pressing the steering wheel.

    74.   We can learn form the text that the driver needs to stop for a break when his response time is ______.

           A. about 400 milliseconds                                 B. below 500 milliseconds

           C. over 500 milliseconds                                          D. about 4 minutes

    75.   When the driver gets sleepy while driving, Driver Alert ______.

           A. moves more regularly                                          B. stops working properly

           C. opens the window for the driver                           D. sounds more frequently and loudly
