Question

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.

1.________ will be developed and used in the construction industry.

A．“Green roofs” that cool or heat buildings

B．“Smart wrap” that catches the sun’s energy

C．Sunlight-measuring sensors that control lights

D．Window coating that lets light in, but keeps heat out

2.The elevators at Seven World Trade Center are special because they can ________.

A．send people to floors with fewer stops

B．teach people how to use their ID cards

C．make people stay very cool in summer

D．help people go traveling in the building

3.The underlined word “it” in the last paragraph refers to ________.

A．a human hair       B．smart wrap         C．the sun’s energy   D．a transmitter

4.What might be the most suitable title for the text?

A．Buildings Are Becoming Smarter

B．Buildings Are Getting More Sunlight

C．Buildings Are Lacking in Much Energy

D．Buildings Are Using Cheaper Materials

【解析】

试题分析：文章主要的介绍了现在和未来的新技术和新的建筑材料使用和看法方面的问题。1.推理题：我们可以以文章最后一句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.为根据。可知选B

2.推理题：根据文章倒数第二段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.为根据。选A

3.推理题：通过句子分析可以看出。文章在最后一段第二句to catch the sun’s energy and… to move it这句话由and连接，显然是并列的成分，由此可以判断提it指代的是the sun’s energy。选C

4.主旨大意题。文章主要的介绍了现在和未来的新技术和新的建筑材料使用和看法方面的问题。A

考点：考查科普类短文

点评：和题目相关的有的涉及到一些长句的理解，要求考生长句的分析能力，并考查学生的概括能力，题目以推理题居多，考生做题时要多的通过句子看到本质。
