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.________ 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 |
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 |
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 |
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 |

2. Severe drought cracks Airport’s runway
KUNMING, March. 18 2010(China Daily)Severe drought continues to plague southwestern China's Yunnan Province.
In the provincial capital Kunming, the surface of Wu Jiaba International Airport's only runway has been fractured(断裂的). Repairs have been going on since Tuesday. The airport is closed every day from midnight to seven-thirty in the morning. Airport authorities say the severe drought is the cause of the damage. The airport also needs to repair its plane taxiing and parking area. Chen Zhiwei, Security Dept., Kunming International Airport, said, "The drought has greatly lowered the underground water level. And this has affected the runway foundations. The damage to its surface is severe."

If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors who say that most of our brains are not getting enough exercise and as a result, we are aging unnecessarily soon
Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of aging could be slowed down.With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and jobs.
Computer technology enabled the researchers to get right measurements of the volume of the front and side sections of the brain, which relate to intellect and emotion, and determine the human character. Contraction (收缩) of the front and side parts as cells died was observed in some subjects in their thirties, but it was still not clear in some sixty and seventy-year-olds.Matsuzawa concluded from his tests that there is a simple remedy (补救) to the contraction normally associated with age using the head.
The findings show in general terms that contraction of the brain begins sooner in people in the country than in towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking (萎缩) brains as farm workers, bus drivers and shop assistants.
Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to keep good blood circulation is through using the brain," he says, "Think hard and engage in conversation. Don't rely on pocket calculators.”
62.The team of doctors wanted to find out ______.
A. why certain people age sooner than others
B. how to make people live much longer
C. the size of certain people's brains

D. The latest development of computer technology.
64.Matsuzawa thinks that _______.
A. our brains grow as we grow older
B. the front section of the brain does not shrink
C. sixty-year-old people have better brains than thirty-year-olds
D. the contraction of brains is connected with brain exercise
654.According to the passage, which people seem to age slower than others?

Our “Mommy and Me” time began two years ago. My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride their bikes up and down. “I wish I could take one of my children out alone,”said Christie.
Then we worked out a plan: When Christie takes one of her children out, I'll watch her other three. And when she watches two of mine, I'll take someone out.
The children were extremely quick to accept the idea of “Mommy and Me” time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. “she's like a different child when there's no one else around,” Christie shared with me quietly. With her mother all to herself, McKenzie didn't have to make an effort to gain attention.
Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering（口吃的） son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And the other son, Sam who's always follower when around other children shines as a leader during our times together.
The “Mommy and Me” time allows us to be simply alone and away with each child--talking, sharing, and laughing, which has been the biggest gain. Every child deserves（应得到） to be an only child at least once in a while.
58.What is the text mainly about?
A. The basic needs of children.
B. The advantage of spending time with one child at a time.
C. The happy life of two families.
D. The experience of the only child being with mother.
59.Right after McKenzie came back, the other children were ________.
A. happy B. curious C. regretful D. friendly
60.What is one of the changes the author finds in her children?
A. Tom has less difficulty in speaking. B. Sam holds her hand more often.
C. The boys become better followers. D. The daughter acts like a leader.
61.The author seems to believe that ________
A. having brothers and sisters is fun B. it's tiring to look after three children
C. every child needs parents' full attention D. parents should watch others' children
When I worked as a waitress in Chicago, US, my coworkers and I would groan (叹息) whenever we heard someone with a foreign accent coming into our restaurant. We knew what it meant to serve a non–American: no tip. We would work just as hard as we always did, but we might not get paid
Americans have an unspoken rule about tipping: they give tips to almost everyone who offers them a service of some kind. Americans tip their waiters, barbers and taxi drivers. An appropriate (合适的) tip is between 15 and 20 percent of the amount charged for the service, but the charge for the tip doesn’t appear on the bill. The customer is expected to add it on himself/herself.
So if you order $100 worth of food, you are expected to pay your waiter at least $15, making your total payment $115. Tipping less than this sends a message to your waiter that you think they’ve done a bad job serving you. And to leave no tip at all is simply unacceptable.
It’s not that American waiters are greedy. In many countries, waiters are paid a salary for their work. They’ll earn money even if no one comes into the restaurant. This system offers much more safety for waiters than the American version. In the US, waiters know that a night without customers means a night without pay.
Some countries include a tip for waiters – a “service charge” – on the bill itself. Since the tip is included with the other charges, waiters don’t need to worry about people forgetting to tip. But in the US, waiters do not receive a salary, and service charges only appear on bills when there are six or more customers at the table.
Since almost all American customers are familiar with the system, they know to add a tip without being told. But visitors to the US may expect waiters to be paid a salary, or think that the tip is included on the bill. So as much as we waiters loved hearing stories about other places from our foreign customers, we were always nervous when they got ready to leave the restaurant. We were never sure what to expect.
55. Why would the author and her coworkers groan when they had to serve a non-American?
A. They would have difficulty understanding the customer.
B. They had to work harder to get tips from the customer.
C. They might not get any payment from the customer.
D. They thought a non-American customer would be hard to please.
56. If you order $550 worth of food, you are supposed to pay your waiter at least ______.
A. $55 B. $82.5 C. $100 D.$110
57. Why would it be thought unacceptable not to tip a waiter in the US？
A. They enjoy getting tips from their customers.
B. They work harder than waiters in other countries.
C. They are greedier than waiters in other countries.
D. They earn most of their money from diners’ tips.

How to Make a Budget
Most likely, you aren’t the family breadwinner. But doing a small job or getting a weekly allowance (零花钱) would put some money in your pocket. For kids and grown-ups alike, money is easy to spend. If you aren’t careful, it can be gone in no time.
Being responsible with your money is an important skill to learn ----and the sooner you start the better. Whether you are tracking your spending or saving for something special, creating a budget can help you deal with your expenses and plan for the future. All you need are paper and a pencil --- and some self-control.
First, take a look at our sample monthly budget. Then, use a separate sheet of paper to plan your own. In the first two columns (栏), list your sources (来源) of income and how much you expect to earn from them. In the third and fourth columns, list what you expect to spend your money on and the amount.
The left-hand total should be more than or equal to the right-hand total. If it is, you have an effective budget.
