They dim immediately when it's sunny md brighten when a passing cloud blocks the sun. A wall of windows at a University of Pennsylvania engineering budding has built-in blinds controlled by a computer program that follows the sun's path. Buildings are getting smarter -- and the next generation of building materials 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 mom 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 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 floor 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 heal while letting in light. More new building materials and technology are in development. A Philadelphia building farm is now working on "smart wrap" that uses tiny solar collectors to catch the sun's energy and transmitters the width of a human hair to move it. They are expected to change the face of the construction industry in the next ten years or so. 【查看更多】

From the moment that an animal is born it has to make decisions. It has to decide which of the things around it are for eating, and which are to be avoided; when to attack and when to run away. The animal is , in fact , playing a very dangerous game with its environment , a game in which it must make decision—a matter of life or death .

Animals’ ability to act reasonably is believed to come partly from what we may call “genetic (遗传性的)learning” , which is different from the individual (个体的) learning that an animal does in the course of its own lifetime . Genetic learning is learning by a

species —animals of the same kind—as a whole , and it is achieved by selection of those members of each generation that happen to act in the right way . However, the role of genetic learning depends upon how similar the future environment is to the past. The more important individual experience is likely to be, the less important is genetic learning as a means of getting over the problems of the survival game. Because most animals live in ever changing environments from one generation to the next, it is not surprising to find that very few species indeed depend wholly upon genetic learning.

In the great majority of animals , their particular ways of acting in a new environment are a compound (复合体) of individual experience added to the action patterns animals are born with .That is why animals can survive.

72．The animal’s life will come to an end .

A．if the animal makes a wrong decision B．if the animal plays a dangerous game

C．when the animal attacks its enemy D．when the animal runs too slowly

73．Very few species depend entirely on genetic learning because .

A．each generation has its own way of learning
