If humans were truly at home under the light of the moon and stars£¬we would go in darkness happily£¬the midnight world as visible to us as it is to the vast number of nocturnal(Ò¹¼ä»î¶¯µÄ) species on this planet. Instead£¬we are diurnal(°×ÌìµÄ) creatures, with eyes adapted to living in the sun¡¯s light. This is a basic evolutionary fact, even though most of us don¡¯t think of ourselves as diurnal beings. Yet it¡¯s the only way to explain what we¡¯ve done to the night: We¡¯ve engineered it to receive us by filling it with light.

The benefits of this kind of engineering come with consequences Ò» called light pollution Ò» whose effects scientists are only now beginning to study. Light pollution is largely the result of bad lighting design£¬which allows artificial light to shine outward and upward into the sky. III-designed lighting washes out the darkness of night and completely changes the light levels Ò» and light rhythms ¡ª to which many forms of life, including, ourselves, have adapted. Wherever human light spills into the natural world, some aspect or life is affected .

In most cities the sky looks as though it has been emptied of stars, leaving behind a vacant haze(ö²) that mirrors our fear of the dark. We¡¯ve grown so used to this orange haze that the original glory of an unlit night, - dark enough for the planet Venus to throw shadow on Earth, is wholly beyond our experience, beyond memory almost.

We¡¯ve lit up the night as if it were an unoccupied country, when nothing could be further form the truth. Among mammals alone, the number of nocturnal species is astonishing, Light is a powerful biological force, and on many species it acts as a magnet(´ÅÌú). The effect is so powerful that scientists speak of songbirds and seabirds being ¡°captured¡± by searchlights on land or by the light from gas flares on marine oil platforms. Migrating at night, birds tend to collide with brightly lit tall buildings.

Frogs living near brightly lit highways suffer nocturnal light levels that are as much as a million times righter than normal, throwing nearly every aspect of their behavior out of joint including most other creatures ,we do need darkness .Darkness is as essential to our biological welfare, to our internal clockwork, as light itself.

Living in a glare of our making,we have cut ourselves off from our evolutionary and cultural heritage¡ªthe light of the stars and the rhythms of day and night .In a very real sense light pollution causes us to lose sight of our true place in the universe, to forget the scale of our being, which is best measured against the dimensions of a deep night with the Milky Way¡ªthe edge of our galaxy arching overhead.

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(°×Ò϶Ñ).

Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building¡ªthe country¡¯s largest commercial and shopping complex¡ªuses 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(Ìì¾®) 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(ͨ·ç¿Ú). 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¡ªdays as warm as 31¡æ commonly drop to 14¡æ 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¡æ and 25¡æ, 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¡ªfar more so than in air-conditioned buildings, where up to 30% of the air is recycled.

1.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.

2.What does ¡°it¡± refer to in Paragraph 3?

A. Hollow space.

B. Baseboard vent.

C. Fresh air from outside.

D. Heat in the building.

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. 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
