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.Why was Eastgate cheaper to be built than a conventional building?
| A．It was designed in a smaller size. |
| B．No air conditioners were fixed in. |
| C．Its heating system was less advanced. |
| D．It used rather different building materials. |
What does “it” refer to in Paragraph 3?
| A．Hollow space. |
| B．Baseboard vent. |
| C．Fresh air from outside. |
| D．Heat in the building. |
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. |
The data in the last paragraph suggests Eastgate’s temperature control system_____.
| A．works better in hot seasons |
| B．can recycle up to 30% of the air |
| C．functions well for most of the year |
| D．allows a wide range of temperatures |
The Touchstone
When the great library of Alexandria burned, the story goes, one book was saved. But it was not a valuable book; and so a poor man, who could read a little, bought it for very little money.
The book wasn’t very interesting, but between its pages there was something very interesting indeed. It was a thin strip of vellum on which was written the secret of the “Touchstone”! The touchstone was a small pebble that could turn any common metal into pure gold.
The writing explained that it was lying among thousands and thousands of other pebbles that looked exactly like it. But the secret was this: The real stone would feel warm, while ordinary pebbles are cold.
So the man sold his few belongings, bought some simple supplies, camped on the seashore, and began testing pebbles. He knew that if he picked up ordinary pebbles and threw them down again because they were cold, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea. He spent a whole day doing this but none of them was the touchstone. Yet he went on and on this way. Pick up a pebble. Cold - throw it into the sea. Pick up another. Throw it into the sea. Pick up another. Throw it into the sea.
The days stretched into weeks and the weeks into months. One day, however, about mid-afternoon, he picked up a pebble and it was warm. He threw it in
to the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea that when the one he wanted came along he still threw it away.
So it is with opportunity. Unless we are careful, it’s easy to fail to recognize an opportunity when it is in hand, and it’s just as easy to throw it away. The man bought the book because _____________.
| A．he wanted to read it | B．it was very interesting |
| C．there was a secret in the book | D．he wanted to find the touchstone |
We can learn from the passage that the touchstone is _________.
| A．pure | B．cold | C．magic | D．big |
Why did the man throw the pebbles into the sea?
| A．Because he didn’t want to get the same pebbles. |
| B．Because he didn’t want others to pick them up. |
| C．Because he didn’t like their ordinary looks. |
| D．Because he didn’t like the cold feelings. |
What does the author want to tell us in the passage?
| A．We should offer opportunities in our life. |
| B．We should seek for opportunities in the world. |
| C．We may seize opportunities when we are watchful. |
| D．We may discover opportunities when forming habits. |
Reading to dogs is an unusual way to help children improve their literacy skills（读写能力）. With their shining brown eyes, wagging tails, and unconditional love, dogs can provide the nonjudgmental listeners needed for a beginning reader to gain confidence, according to Intermountain Therapy Animals (ITA) in Salt Lake City. The group says it is the first program in the country to use dogs to help develop literacy in children, with the introduction of Reading Education Assistance Dogs (READ).
The Salt Lake City Public Library is sold on the idea. “Literacy specialists admit that children who read below the level of their fellow pupils are often afraid of reading aloud in a group, often have lower self-respect, and regard reading as a headache.” said Lisa Myton, manager of the children’s department.
Last November the two groups started “Dog Day Afternoon” in the children’s department of the main library. About 25 children attended each of the four Saturday-afternoon classes, reading for half an hour. Those who attended three of the four classes received a “pawgraphed” book at the last class.
The program was so successful that the library plans to repeat it in April. According to Dana Thumpowsky, public relations manager.．What is mainly discussed in the text?
| A．A special reading program. | B．Advantages of raising dogs. |
| C．Service in a public library. | D．Children’s reading difficulties. |
Specialists use dogs to listen to children reading because they think ________.
| A．dogs are young children’s best friends |
| B．dogs can provide encouragement for shy children |
| C．children can play with dogs while reading |
| D．children and dogs understand each other |
By saying “The Salt Lake City Public Library is sold on the idea,” the writer means the library ____________.
| A．accepts the idea put forward by ITA | B．uses dogs to attract children |
| C．has opened a children’s department | D．has decided to train some dogs |
A “pawgraphed” book is most probably _________.
| A．a book used in Saturday classes | B．a prize for the children |
| C．a book written by the children | D．a gift from parents |
