My brother and I were in Orlando Florida to witness our first Space Shuttle Launch. The Discovery was to soar at 10:14 AM on a blue sky September day. I’d seen it so many times on television, now I was only minutes away from seeing it launch. And it’s the final demonstration of the of success: Success Takes Off Like a Rocket.

Witnessing the Take Off:

Standing close to the Space Shuttle home one unforgettable point—the Shuttle is the height of a 15-story building—it 4.5 million pounds—and NASA is trying to lift it 200 miles off the ground. On TV the accomplishments look so much , so much easier.

Crowds of people are standing around with you to watch the Shuttle go. The countdown begins through the small of hundreds of portable radios all tuned to the NASA station. It’s enough to get your heart beating .

When time is up, the side booster rockets are lit up and the eight explosive bolts . The first things you see are large white clouds exploding away. Through the steam, you see the fire power. Then the Space Shuttle begins to inch off the pad and climb its way . Thousands upon millions of pounds of can hardly lift the shuttle at all. But with ever increasing ease, the shuttle picks up and roars into the sky, headed into space attaining a of over 17,000 mph.

It is within the first two minutes to launch the Space Shuttle that the great success lesson is . Fact: 85% of the shuttle’s fuel is consumed within the first 2 minutes just to get the 15-story super structure to its orbital .

And that’s exactly how success : The first steps you take towards launching a successful career are the and will require an enormous consumption of energy—a great big push. However, you persist through the launch period, which can seem almost for quite some time, everything gets easier and easier and your results get bigger and bigger.

Zebras have their own bug repellent(驅(qū)蟲劑)?

Eww bugs! They are so annoying! We humans are lucky that we can apply repellents to avoid nasty bites. But what’s an animal to do? They have no choice but to spend their days shooing them off with their tails, unless, of course, they are zebras, who apparently have their own automatic repellent--- their striped skin!

Scientists had originally thought that the reason why the animal had developed the black and white lines was to help protect itself from predators in the African savannah, because the stripes make it difficult to single out one zebra that is traveling with a herd.While that may be true, the theory has never been tested or proven. Now the experts have another---that the stripes have evolved to repel the annoying horse flies that not only feed off their blood, but also, transmit dangerous germs into the bodies of these innocent animals.

The study was performed by a team of Swedish scientists. One of the clues that got them thinking along these lines was the fact that darker horses got bitten more often than light-colored or white ones.

The fact that zebras are born black and only develop strips as they grow older made the scientists theorize that the stripes may be something the animals have developed to make themselves less attractive to flies.

To test if this may be the case, they painted some boards at a horse-infested horse farm in Budapest with patterns of black and white stripes of varying widths and applied a layer of glue on them. What they noticed was that the places where the black and white stripes were at their narrowest (similar to what zebras have) attracted the fewest flies. They achieved similar results when they painted horses with black and white zebra-like stripes.

While the research are not sure why this may be the case, they believe it may be something to do with the way insects operate---horseflies are attracted to horizontally polarized light（偏振光）; since white does not reflect it, white horses are luckier than black ones. But zebras seem to be the luckiest of all. When the researchers measured the polarized light reflected from real zebra skins, they found that it matched light patterns that were the least attractive to horseflies.

While this theory does make logical sense, nobody is 100 percent sure that it is really true, given that it has never been tested on a real zebra. If it is true, it does raise the question of why a horse, a close relative of the zebra has failed to develop stripes. The researchers believe that this could be because there are more horseflies in Africa, where zebras reside, then anywhere else in the world.

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(白蟻堆).

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 plant 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(通風(fēng)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 swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically 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.

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. 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
