In Chicago, a computerized system has been developed that controls(管理)traffic on the city’s 235 miles of seven expressways. Now one—a controller—can follow the movement of Chicago’s traffic by looking at a set of lights. The system uses electric sensors(感应器) that are built into each expressway, every half a mile. Several times a second, the computer receives information from each sensor and translates it into green, yellow or red lights on a map in the control room. A green light means traffic is moving forty-five miles an hour, yellow means thirty to forty-five miles an hour, and red means heavy traffic—cars standing still or moving less than thirty miles an hour.
“See that red light near Austin Avenue?”the controller asked a visitor.“That’s a repair truck fixing the road, and the traffic has to go around it.”At the Roosevelt Road entrance to the expressway, the light kept changing from green to red and back to green again.“A lot of trucks get on the expressway there,”the controller explained.“They can’t speed up as fast as cars.”The sensors show immediately where an accident or a stopped car is blocking the traffic, and a truck is sent by radio to clear the road. The system has lowered the number of accidents by 18 percent. There are now 1.4 deaths on Chicago’s expressway for each one hundred million miles traveled, while in other parts of the county there are 2.6.
Traffic experts say that the Chicago system is the “coming thing”.Systems like Chicago’s are already in use on some expressways in Los Angeles and Houston.“Chicago has taken the lead,”said New York City’s traffic director and he added,“Chicago’s a good example.”

Mary picked up a pencil and a piece of paper,saying,“Now,you want to earn money for the autumn camping trip,right?” Tom,her brother,nodded.He wasn’t able to go last year because he hadn’t earned enough money during the summer.This year he came up with a plan.
He made a necklace for his mother that everyone admired.They were surprised to learn that Tom had made it for her.Why not make more necklaces and sell them?
“OK,” said Mary,“The first thing you need to do is to figure out(计算)how much you have now.’’
“I have $20.00 in the bank,and $7.25 in my room,” explained Tom.
“That gives you a total of $27.25,” said Mary,“That is called your capital.The next thing you need to know is how much it will cost you to make each necklace.”
“Well,the pet shop will give me all the feathers the birds lose.I'll have to buy the beads(小珠子)and string,” said Tom.
Mary wrote on the piece of paper:
CAPITAL $27.25
EXPENSES Feathers no cost
String for 10 necklaces $ 2.50
Beads for 10 necklaces + $ 15.00
Total $ 17.50
“How much do you think you can sell such a necklace for?” asked Mary.
“Hmm,” Tom looked thoughtful and said,“There's a shop in town that sells almost the same kind of necklace for $ 7.50.If I charge(要价)$ 6.00,people will think that's a bargain.”
“OK.If you sell each necklace for $ 6.00,you'll make a good profit(利润)on each then,” said Mary.
“Hurray!” Tom cried,“If I sell 20 necklaces,I'll have enough from the profit for the camping trip and $10.00 left over.”
