At Dallas/Fort Worth Airport, the lights are controlled by sensors that measure sunlight. They dim immediately when it’s sunny and brighten when a passing cloud blocks the sun.
A wall of windows at a University of Pennsylvania engineering building has built-in blinds (百叶窗) controlled by a computer program that follows the sun’s path. Buildings are getting smarter and the next generation of building materials is expected to do even more.
Windows could catch the sun’s energy to heat water. Sensors that measure the carbon dioxide breathed out by people in a room could determine whether the air conditioning needs to be turned up.
Many new materials and technology have been designed in the last 15 years. They are now being used in a wave of buildings designed to save as much energy as possible. They include old ideas, like “green roofs”, where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new ideas, like special coating for windows that lets light in, but keeps heat out.
As technologies such as sensors become cheaper, their uses spread.
The elevators at Seven World Trade Center, which is under construction in New York, use a system that groups people traveling to nearby floors into the same elevator, thus saving elevator stops. People who work in the building will enter it by swiping (刷) ID cards that will tell the elevators their floor, readouts will then tell them which elevator to use. The building also has windows with a coating that blocks heat while letting in light.
More new building materials and technology are in development. A Philadelphia building firm is now working on “smart wrap” that uses tiny solar collectors to catch the sun’s energy and transmitters (传输器) as wide as a human hair to move it. They are expected to change the face of the construction industry in the next ten years or so.

B.Buildings Are Getting More Sunlight |
C.Buildings Are Lacking in Much Energy |
D.Buildings Are Using Cheaper Materials |
The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audience could see his hero and heroine in front of it at the end of the film as they said goodbye to each other forever. He sent his camera crew out one evening to film the sunset for him.
The next morning he said to the men, “Have you provided me with that sunset?”
“No, sir,” the men answered.
The director was angry. “Why not?” he asked.
“Well, sir,” one of the men answered, “we’re on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”
“But I want a sunset!” the director shouted. “Go to the airport, take the next flight to the west coast, and get one.”
But then a young secretary had an idea. “Why don’t you photograph a sunrise,” she suggested, “and then play it backwards? Then it’ll look like a sunset.”
“That’s a very good idea!” the director said. Then he turned to the camera crew and said, “Tomorrow morning I want you to get me a beautiful sunrise over the sea.”
The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay. Then at nine o’clock they took it to the director. “Here it is, sir,” they said, and gave it to him. He was very pleased.
They all went into the studio. “All right,” the director explained, “now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the ‘sunset’ behind them.”
The “sunset” began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.
The birds in the film were flying backwards, and the waves on the sea were going away from the beach.
【小题1】One evening, the director sent his camera crew out _________.
A.to film a scene on the sea |
B.to find an actor and an actress |
C.to watch a beautiful sunset |
D.to meet the audience |
A.Because he changed his mind about getting a sunset. |
