The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蚁堆).

Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning equipment didn’t have to be imported.

The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.

During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.

This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature changes—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its hot summers and cold winters,” Pearce said.

The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned buildings, where up to 30% of the air is recycled.

A. Fresh air from outside. B. Heat in the building.

C. Hollow space. D. Baseboard vent.

3.Why would a building like Eastgate Not work efficiently in New York?

A. New York has less clear skies as Harare.

B. Its dampness affects the circulation of air.

C. New York covers a larger area than Harare.

D. Its temperature changes seasonally rather than daily.

4.The data in the last paragraph suggests Eastgate’s temperature control system_____.

A. allows a wide range of temperatures

B. functions well for most of the year

C. can recycle up to 30% of the air

D. works better in hot seasons

When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.

These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society,” said George Vaillant, the psychologist (心理学家) who made the discovery. “And because they felt good about themselves, others felt good about them.”

Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men’s mental-health scores with their boyhood-activity scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.

The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out. Working----at any age----is important. Childhood activities help a child develop responsibility, independence, confidence and competence---the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn’t everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one’s work.”

1.What do we know about John?

A. He enjoyed his career and marriage.

B. He had few childhood playmates.

C. He received little love from his family.

D. He was envied by others in his childhood.

2. Vaillant’s words in Paragraph 2 serve as _____.

A. a description of personal values and social values

B. an analysis of how work was related to competence

C. an example for parents’ expectations of their children

D. an explanation why some boys grew into happy men

3. Vaillant’s team obtained their findings by _____.

A. recording the boys’ effort in school

B. evaluating the men’s mental health

C. comparing different sets of scores

D. measuring the men’s problem solving ability

4. What does the underlined word “sharp” probably mean in Paragraph 4?

A. Quick to react

B. Having a thin edge

C. Clear and definite

D. sudden and rapid

5. What can be inferred from the last paragraph?

A. competent adults know more about love than work.

B. Emotional health is essential to a wonderful adult life.

C. Love brings more joy to people than work does.

D. Independence is the key to one’s success.

A warm drink of milk before bed has long been the best choice for those wanting a good night’s sleep. But now a study has found it really does help people nod off—if it is milked from a cow at night.

Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.

The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.

Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

Night milk quickened the start of sleep and caused the mice to sleep longer.

While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.

Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

1.According to the text, the mice fed with daytime milk_______.

A. started sleep more easily

B. were more anxious

C. were less active

D. woke up later

2.Which of the following is true of melatonin according to the text?

A. It’s been tested on mice for ten years

B. It can make people more energetic

C. It exists in milk in great amount

D. It’s used in sleeping drugs

3. What can be a suitable title for the text?

A. Night Milk and Sleep

B. Fat Sugar and Health

C. An Experiment on Mice

D. Milk Drinking and Health

4.How does the author support the theme of the text?

A. By giving examples.

B. By stating arguments.

C. By explaining statistical data.

D. By providing research results.

A new collection of photos brings an unsuccessful Antarctic voyage back to life.

Frank Hurley’s pictures would be outstanding----undoubtedly first-rate photo-journalism---if they had been made last week. In fact, they were shot from 1914 through 1916, most of them after a disastrous shipwreck(海滩), by a cameraman who had no reasonable expectation of survival. Many of the images were stored in an ice chest, under freezing water, in the damaged wooden ship.

The ship was the Endurance, a small, tight, Norwegian-built three-master that was intended to take Sir Ernest Shackleton and a small crew of seamen and scientists, 27 men in all, to the southernmost shore of Antarctica’s Weddell Sea. From that point Shackleton wanted to force a passage by dog sled(雪橇) across the continent. The journey was intended to achieve more than what Captain Robert Falcon Scott had done. Captain Scott had reached the South Pole early in 1912 but had died with his four companions on the march back.

As writer Caroline Alexander makes clear in her forceful and well-researched story The Endurance, adventuring was even then a thoroughly commercial effort. Scott’s last journey, completed as be lay in a tent dying of cold and hunger, caught the world’s imagination, and a film made in his honor drew crowds. Shackleton, a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908, started a business before his 1914 voyage to make money from movie and still photography. Frank Hurley, a confident and gifted Australian photographer who knew the Antarctic, was hired to make the images, most of which have never before been published.

1.What do we know about the photos taken by Hurley?

A. They were made last week

B. They showed undersea sceneries

C. They were found by a cameraman

D. They recorded a disastrous adventure

2.Who reached the South Pole first according to the text?

A. Frank Hurley B. Ernest Shackleton

C. Robert Falcon Scott D. Caroline Alexander

3.What does Alexander think was the purpose of the 1914 voyage?

A. Artistic creation

B. Scientific research

C. Money making

D. Treasure hunting
