Controlling traffic is a complex and high cost problem in many developed countries. It becomes more difficult and costly with the ever- increasing number of cars on the roads. But scientists and students at the CATT, at the University of Maryland are working to solve this problem. They are using simulation(模拟) technologies to help government and private business control and react to changing traffic conditions.

The online economics magazine Forbes.com says traffic congestion(拥挤) cost Americans $ 124 billion in 2014 and that number could rise to $ 186 billion by 2030.

Bui scientists at the CATT lab are trying to reduce those costs. They are developing a system that helps traffic managers. planners, emergency workers and businesses plan and react better. Michael Pack is CATT director. He says the system is important to help emergency workers, or first responders,reach an accident area faster.

The CATT Lab collects information from many sources, including roadside devices, GPS (global positioning system) equipment and wireless phones.

About 60 students and 30 software developers observe traffic flow and manage the computer servers at all times. They also work to develop software and applications that can help traffic run smoother and safer, Some of them turn the information gathered into so-called "visualizations". These visual representations help emergency workers better understand what is happening.

The center shares its findings with firefighters, police,Transportation departments and the military. They also share information with universities and transportation company. The technology company Google uses the data for its traffic-related websites. Michael Pack says, the information is then shared with anyone who wants to help traffic run more smoothly.

Mr. Pack says the goal is to help develop an intelligent system of road signals that will communicate with each other and with vehicles on the road.

Cheaters called “pirates” often use camcorders(便携式摄像机) and cell phones to make illegal copies of blockbusters in the local theater. These pirates then sell those recordings on the street or over the Internet for very low prices. Some share them for free.

“It’s unfair for people to pirate movies,” says 15-year-old Hadaia Azad Ezzulddin. Movie piracy “takes money out of the pockets of thousands of people in the movie industry,” she notes. Victims include famous actors and directors as well as local theater owners and their employees.

Hadaia came up with an idea that could help stop movie piracy. Hadaia’s idea uses infrared(红外线的) light. This range of light is invisible to the human eye. It is visible, however, to many types of cameras. Theater owners could place small infrared lights on their movie screens. The lights would not disturb people watching the movie. It would, however, distort the recordings made by many types of cameras.

To test her idea, Hadaia built a box with a movie screen inside. Then, she projected images on that screen through a hole in the box. She took recordings of those images, using nine different types of cameras. These included the types found in cell phones as well as camcorders. During some tests, she also turned on light emitting diodes(发光二极管), or LEDs. The LEDs were embedded(植入的)in a certain place behind the movie screen. They gave out infrared light.

Sure enough, she showed, a pirated movie included odd stripes or spots if it had been recorded while the LEDs were on. It might be possible to use the LEDs to flash the date and time on the movie screen. The information would then appear in the illegal recordings. Theater owners or police might use the information to track down the pirates.

Cutting down on piracy might get more people into theaters to watch the real movie instead of an illegal copy. Six out of every ten films now produced aren’t profitable. They don’t make enough money to recover how much was spent to make and market them. Such a poor payback can discourage filmmakers from producing anything but the types expected to become blockbuster hits. It might also keep smaller theaters from showing a wider variety of movie types.

1.From what Hadaia says in Paragraph 2, we can infer that _______.

A. most people spend less money on pirates moves

B. the pirates don’t have to pay for the movie tickets

C. theater owners will increase the price of movie tickets

D. she strongly criticizes those who video movies in the theater

2.Infrared lights are put on the movie screens to _______.

A. adjust the brightness of the movie screens

B. make sure the images of movies are dark

C. make illegal copies of movies unpleasant to see

D. protect the eyesight of viewers in the darkness

3.What is the correct order of the steps in Hadaia’s test?

a. She projected pictures on the screen.

b. She used cameras to record the pictures.

c. She turned on the LEDs placed behind the screen.

d. She made a special box with a movie screen inside.

A. d c a b B. d b a c

C. b a c d D. b c a d

4.According to the last paragraph, we can know that _______.

A. forty percent of movies now are profitable

B. small theaters often choose to show low-cost movies

C. more and more people go to theaters to fight movie piracy

D. filmmakers prefer to produce ordinary movies than blockbusters
