There were no rush hours any more," said Charles M. McLean,who runs the nation' s busiest road. "We have rush periods, and they keep getting longer and longer."
McLean was describing 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 look?ing 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 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 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 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," says New York City,s traffic director;and he adds,"We are far behind!”
( ) 8. By saying "Chicago has taken the lead” ,the director means .
A. Chicago has taken something very heavy
B. they are under the control of Chicago
C. Chicago is ahead of them in using the system
D. Chicago is the center of all the systems in the US
( ) 9. Why did the controller ask a visitor?
A. He wanted to tell him how the lights work.
B. He cited it as an example to show the visitor what the lights tell.
C. He showed the visitor what he does.
D. He was teaching him how to control the system.
( ) 10. Where is the passage most probably taken from?
A. A science book. B. A travel journal.
C. A magazine. D. A student text.
( ) 11. What,s the main idea of the passage?
A. The computerized traffic control system greatly helps in Chicago.
B. Rush periods in Chicago are getting longer.
C. Chicago has the busiest road in the nation.
D. The expressways are faster now.
( ) 12. What can we learn from the passage?
A. The controller follows Chicago,s traffic by waiting for the red light to turn to green.
B. The sensor can immediately deal with the accidents.
C. The system has greatly helped to reduce the deaths on the expressways.
D. At the entrance to the expressway,the lights can change only because of the speed of the trucks.

科目:高中英語(yǔ) 來(lái)源: 題型:
Scientists in the United States say plant life has increased on Earth in the past twenty years and that in every area of plant growth the increase is the result of weather conditions.
Eight scientists from across the United States did the study. The space agency NASA and the Department of Energy paid for it. The findings were published in the magazine Science.
The researchers spent one and a half years examining weather satellite information. The in?formation was recorded from 1982 to 1999. That period was one of the warmest on record. Re?searchers found that rainfall generally increased during that time.
The satellites measured the number of leaves on plants and the amount of sunlight taken in. The scientists used that information to estimate what is called net primary production. This is to?tal amount of carbon stored in land plants.
The scientists report a 6% increase in stored carbon since 1982. They say gains were high in equatorial areas,especially around the Amazon River in South America. The area alone had a 1% increase in the net primary production.
Ramakrishna Nemani of the University of Montana in Missoula headed the study. He says reduced cloud cover led to growth in Amazon area. He also says the lack of clouds allowed more sunlight to get through. More sunlight meant increases in photosynthesis(光合作用) .That is the process by which plants use energy from sunlight to produce the chemicals they need to grow.
Northern Canada, the north-central United States and northern Europe were second in increased plant growth. Ramakrishna Nemani says a rise in temperature helped plants there.
All together, the report says 25% of areas of plant life on Earth experienced increases. But the scientists also note increase in the number of people on Earth and carbon dioxide levels in the atmosphere. Ranga Myneni of Boston University in Massachusetts, another study scientist says humans use about half the net primary production on Earth. And he notes that the world popula?tion grew by 36% during the period of time studied.
( ) 5. Which of the following is in charge of the study?
A. The space agency NASA of the US.
B. The Department of Energy of the US.
C. Ramakrishna Nemani in Missoula.
D. Ranga Myneni in Massachusetts.
( ) 6. What's the main cause of the plant growth put forward by the study?
A. Growth in population. B. Regional features.
C. Seasonal variation. D. Weather conditions
( ) 7. Why do scientists believe that reduced cloud cover has led to the plant growth in the Amazon area?
A. Because plants could take in more sunlight.
B. Because plants could get more rainfall.
C. Because plants could enjoy cooler air.
D. Because plants suffer less from natural disasters.
( ) 8. Which of the following descriptions agreed with what the years from 1982 to 1999 suggested?
A. It was the warmest on record.
B. Rainfall decreased little by little.
C. World population grew by 25%.
D. Stored carbon increased by 6%.
