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

 

When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive , people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.

Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock. During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.

People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas, instead of keeping livestock on the first floor builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy saving.

House building becomes a great challenge to building designers and energy engineer. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy saving houses.

1.What did people begin to consider as electricity was no longer cheap?

A．The climate of their areas.                 B．The energy for their houses.

C．The fashions for their houses.              D．The building materials for their houses.

2.People in some areas gain a source of heat by _________.

A．keeping their livestock downstairs

B．protecting their livestock from the cold

C．sharing their houses only with their cows

D．living on the second floor with their livestock

3.The underlined words “natural law ” in the third paragraph refer to the fact that ________.

A．heat raises the temperature in the houses

B．heat goes in the upward direction

C．heat goes up if temperature is raised

D．heat increases the temperature of rocks

4.From the passage, we can conclude that _______ .

A．people will no longer consider building materials in the future

B．energy saving buildings will become more popular in the future

C．almost all people will move into the houses heated by large rocks

D．energy engineers will devote themselves only to modern technology

5.What is the meaning of the underlined word “livestock” ? _______ .

A．animals raised especially for economical benefits   B．furniture

C．plants kept in the house                  D．general appearance of the whole family

 

China news, Beijing, Feb. 9 – Housing price in China has always aroused heated discussions among property developers（房产开发商）and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate market, the International Finance News reported.

Although the average price of residential houses in the United States, after converted（转换）to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold a t a price even higher than those in the US.

The high housing sales price in large cities in China proves that Chinese real estate（房地产）market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people’s average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?

At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate (控制) the real estate market by raising tax on property industry and controlling the release of loans（贷款）and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.

1.What is the average housing price per square meter in China?

         A．8000 yuan.              B．10000 yuan.            C．7000 yuan.              D．it’s not mentioned here.

2.Which of the following does NOT support the idea that the average housing price in China is  even higher than in the United States?

        A．Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities.

        B．American people’s average income is several dozen times higher than that of Chinese       

people.

        C．The houses in US are not sold in terms of building area, as most Chinese property       

developers do when they sell their houses.

        D．There population who need houses in China than in the United States.

3.How many measures are mentioned in the last paragraph in order to reduce the high housing  prices?  

         A．Four.                        B．Three.                     C．Tow.                         D．One.

4.What is the main idea of this passage?

      A．The housing price in China is so high that the government should do something useful to

prevent it.

        B．There are some bubbles in Chinese real estate market.

        C．The average housing price in China is even higher than in the United States.

        D．The Chinese government issued a set of policies that aimed to benefit the public.
