Text Analysis

(Directions:) In this part, the author lists the features of smart cars. Can

you summarize these features?

(Tips:    1.   Smart cars can eliminate most car accidents.

2.   Smart cars can alert the police and provide precise location if stolen.

3.    Smart cars can monitor one’s driving and the driving conditions nearby.

4.      Smart cars alert the sleepy driver.

5.      Smart cars can locate your car precisely and warn of traffic jams.)

 

Language Focus

       We may encounter some difficult words or phrases in reading. Shall we consult the dictionary immediately? An efficient reader will make a guess based on knowledge of word-formation or knowledge of the word in the context.

For example, can you guess the meaning of “blink spot” in the following sentence?

Should you make a serious driving mistake (e.g., change lanes when there is a car in your “blind spot”) the computer would sound an immediate warning.

There might be an accident if you change lanes when there is a car in your “blind spot”. How could it happen? How come you don’t know the existence of the car? It must be that you cannot observe the car from the rear-view mirror. Here comes the possible meaning of “blind spot”: a portion of the road behind a car, which a driver cannot observe from the rear-view mirror.

       Now try to guess the meaning of “Global Positioning System”(Para. 7) and “atomic clocks”(Para. 7).  

       Word-formation may also provide much information about the meaning of the word.

       For example, what is telematics? The prefix “tele-” means “distant”, the suffix “-matics” may be the end part of “informatics”. So telematics must be a branch of knowledge concerned with long-distance transmission.

       Now try to guess the meaning of “prototype” (Para. 6) and “interstate” (Para. 12).
