Pair Work
1、How important was the automobile industry in the twentieth century?
The automobile industry ranked as among the most lucrative and powerful industries of the twentieth century、
2、What will happen to cars and roads in the twenty-first century?
Cars and roads will be revolutionized in the twenty-first century、
3、Why does the author say the key to tomorrow's "smart cars" will be sensors?
Because it is sensors that will enable vehicles and roads to be able to see, hear, feel, smell, talk, and act、
4、How would sensors help reduce traffic fatalities?
Sensors can sense if a driver is drunk and refuse to start up the engine、
5、What is the function of the radars hidden in the bumpers?
The radars hidden in the bumpers can scan for nearby cars、If you make a serious driving mistake the computer will sound an immediate warning、
6、How will a smart car alert a driver who feels drowsy?
If the driver's eyelids close for a certain length of time and his or her driving becomes erratic, a computer in the dashboard could alert the driver、
7、What makes it possible for smart cars to determine their approximate location?
CHILDRENUNDERTHEAGEOF10GPS makes it possible for smart cars to determine their location on the earth to within about a hundred feet、
8、What are the prospects for applications of GPS?
骨质瓷With the price of microchips dropping so drastically, future applications of GPS are virtually limitless、
9、What is "telematics" expected to achieve in increasing the efficiency and safety of highway
transportation?
It is expected to put smart cars on smart highways、
10、What are traffic engineers doing on Interstate 15 close to San Diego?
They are installing an MIT-designed system which will introduce the "automated driver"、11、What hopes do promoters of the smart highway have for its future?
They have great hopes for its future、By 2010, telematics may well be incorporated into one of the major highways in the United States、By 2020, telematics could be adopted in thousands of highways in the United States、
12、What are the advantages of smart highways?
Smart highways could be an environmental boon, saving fuel, reducing traffic jams, decreasing air pollution, and serving as an alternative to highway expansion、
