"We have rush periods, and they keep getting longer and longer." Mac Lean was describing prefix = st1 /Chicago's 235 miles of expressway. But the same might be said about almost any of the expressways that have become an important part of American city life--and about the heavy traffic that often blocks them. In Chicago, a computerized system has been developed that controls traffic on the city's seven expressways. Now one man--a controller--can follow the movement of Chicago's traffic by looking at a set of lights. The system uses electronic sensors that are built into each expressway, half a mile apart. 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 the 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 Roadentrance 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 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 expressways for each one hundred million miles traveled, while in other parts of the country there are 2.6. Traffic experts say that the Chicagosystem is the "coming thing". Systems like Chicago's are already in use on some expressways in Los Angeles andHouston. "Chicago has taken the lead," saysNew York City's traffic director; and he adds, "We are... Question: Which of the statements is true about the computerized system in Chicago?

D: It will soon be followed by New York City.

Read the article and select the best answer. Article: There is no doubt that much of the profit of a business--sometimes the whole of its success--depends upon the use of the odds and ends.The odds and ends are various small things,which are left over when the main things are produced.But they possess a real value of their own. If a business,big or small,looked down upon these odds and ends,it would mean a big difference in the amount of the benefit of the business.Take a meat factory for instance, there are countless odds and ends--bones and hair,which can be made into glue and rope to increase its profit greatly. Then,if we are college students,what about our odds and ends--the odd moments? Take time for example.Every one of us has the exact same amount of it.Everyone's success or failure depends on the use of their time.But everyone uses the time more or less in the same way.However,why many great men in science or art have made huge successes for themselves in the world?Because they have made best use of their odd moments.Take Thomas A.Edison, he never allowed his odd moments to slip by.He thought,planned,and tried his inventions.He always worked twenty hours out of each twenty-four.His inventions made him famous all over the world,and provided valuable wealth for the human beings. So, remember this axiom:very busy people always find time for everything.However,people with great spare time find time for nothing.Is it very strange?Not at all!The question is how to gather up fragments of time and make full use of them.As many big businesses have found,that the real profit is in using the odds and ends.We also must do in this way to make best use of our odd moments and manage to be successful in something that we do. Question: What are odds and ends? Options: A: They are nothing useful. B: They are various small,but valuable things. C: They are the main things that factories produce. D: They are odd moments students deny to gather up.
