The devastation of Typhoon Morakot over Taiwan and eastern China is a reminder that the northwest Pacific is the most dangerous region in the world for tropical storms．The worst of these are typhoons, which are the same as hurricanes in the Atlantic and eastern Pacific, or cyclones in the Indian Ocean and Australia．They all have winds of more than 118km/h (73mph) spinning around a central core．
These storms start off as a mass of thunderstorms in the tropics outside the Equator．Given the right conditions, they form a bigger and more organised storm and feed off warm seas at more than 26．5C (80F) to get the fuel that they need to become a fully-fledged(羽毛丰满的) typhoon, hurricane or cyclone．Each storm is like a heat engine, extracting heat from the warm, humid air over the sea and turning it into phenomenal amounts of energy — equivalent to about 200 times the entire world’s electrical generating capacity．But warm, moist air is not enough — these storms also need slack winds aloft, because strong high-altitude winds can rip off the top of the storm clouds and send the entire storm tumbling（翻跟头）．
The damage from tropical storms often comes from their winds, or the storm surges from the sea as the winds pile up water into a huge battering ram(冲击夯) that floods coastlines．But the devastation from Typhoon Morakot came from its unbelievable rainfall — about a year’s average rain in some places — that set off landslides and mudslides．

When I told my father that I was moving to Des Moines, Iowa, he told me about the only time he had been there. It was in the 1930s, when he was an editor if the literary magazine of Southern Methodist University（SMU）in Dallas, Texas. He also worked as a professor at SMU, and there was a girl student in his class who suffered from a serious back disease. She couldn;t afford the operation because her family was poor.
Her mother ran a boardinghouse in Galveston, a seaside town near Houston, Texas. She was cleaning out the attic（阁楼）one day when she came across an old dusty manuscript（手稿）. On its top page were the words, “By O. Henry”. It was a nice story, and she sent it to her daughter at SMU, who showed it to my father. My father had never read the story before, but it sounded like O. Henry, and he knew that O. Henry had once lived in Houston. So it was possible that the famous author had gone to the beach and stayed in the Gainestown boardinghouse, and had written the story there and left the manuscript behind by accident. My father visited an O. Henry expert at Columbia University in New York, who authenticated the story as O. Henry’s.
My father then set out to sell it. Eventfully, he foud himself in Des Moines, meeting with Gardner Cowles, a top editor at the Des Moines Register. Cowles loves the story and bought it on the spot. My father took the money to the girl. It was just enough for her to have the operation she so desperately needed.
My father never told me what the O. Henry story was about. But i doubt that it could have been better than his own story.Who found the O. Henry’s manuscript?
| A．The girl’s mother. | B．The author’s father. |
| C．The girl. | D．The author. |
Which of the following might explain the fact that the manuscript was found in the attic?
| A．O. Henry once worked in Houston. |
| B．O. Henry once stayed in Galveston. |
| C．O. Henry once moved to Des Moines. |
| D．O. Henry once taught at SMU. |
The underlined word “authenticated” in Paragraph 2 probably means __________.
| A．named | B．treated | C．proved | D．described |
According to the text, why did the author’s father go to Des Moines?
| A．To sell the O. Henry story. | B．To meet the author himself. |
| C．To talk with the O. Henry expert. | D．To give money to the girl. |
Our warming planet is expected to face serious water crisis（危机）in the coming decades — which means each nation’s natural resource will be more important than ever.  |

It's generally believed that people act the way they do because of their personalities and attitudes. They recycle their garbage because they care about the environment. They pay $5 for a caramel brulee latte because they like expensive coffee drinks.
It's undeniable that behavior comes from our inner dispositions（性情）, but in many instances we also draw inferences about who we are, as suggested by the social psychologist Daryl Bern, by observing our own behavior. We can be strangers to ourselves. If we knew our own minds, why should we need to guess what our preferences are from our behavior? If our minds were an open book, we would know exactly how much we care about the environment or like lattes. Actually, we often need to look to our behavior to figure out who we are.
Moreover, we don't just use our behavior to learn about our particular types of character --- we infer characters that weren't there before. Our behavior is often shaped by little pressures around us, which we fail to recognize. Maybe we recycle because our wives and neighbors would disapprove if we didn't. Maybe we buy lattes in order to impress the people around us. We should not mistakenly believe that we always behave as a result of some inner disposition.
Whatever pressures there can be or inferences one can make, people become what they do, though it may not be in compliance（符合）with their true desires. Therefore, we should all bear in mind Kurt Vonnegut's advice: "We are what we pretend to be, so we must be careful about what we pretend to be."

One moment it was quiet and calm in the forest, the next, the air was charged with tension. The elephant had heard the distant alarm calls of animals and her mood suddenly changed. I urged the elephant deeper into the forest. We sounded like a forest fire --- cracking, snapping, trailblazing. But through all the noise came a sharp warning cry. The elephant stopped and we heard it again --- the tell-tale call of a spotted deer.
I looked quickly around the shadows of the forest. Rays of sunlight shone through tree branches, beneath which the patchwork（交错）of green plants and shadows-within-shadows would make tiger stripes（条纹）look more attractive. Apart from an occasional noise from the elephant’s stomach, the forest was silent.
Gradually, the tension slipped from our bodies. The elephant seized a nearby branch and put it into its mouth. I reached forward and gently moved my hand over the elephant’s neck; there was a soft part, free of wrinkles and hairs, behind her ear.
This was my fourth time to sense the aura of the forest in Corbett, although I saw no tigers in the end. Located at the foot of the Himalayan mountains, Corbett is home to about 135 Bengal tigers, but the forest seemed to be guarding their whereabouts（出没处）, a silent reminder of their secrecy and rarity. Still, I was happy enough touching the elephant behind the ear. If I had so desperately wanted to see a tiger, I could have gone to a zoo. After all, spotting tigers merely confirms their beauty; tracking them can make you aware of something more.Which of the following was a clear signal of alarm?
| A．The elephant stopped. |
| B．A spotted deer called. |
| C．The elephant seized a branch. |
| D．The forest was silent for a while. |
The author begins his account of the tour in the forest mainly by _______.
| A．describing various sounds |
| B．comparing different animals |
| C．listing different activities |
| D．introducing various plants |
What does the underlined part “to sense the aura” most probably mean?
| A．To see the diversity. |
| B．To enjoy the scenery. |
| C．To feel the atmosphere. |
| D．To experience the freedom. |
How does the author feel after several visits to Corbett?
| A．Seeing a Bengal tiger is quite thrilling. |
| B．It is very time-consuming to travel in Corbett. |
| C．It is really worthwhile to study the animals in Corbett. |
| D．The process of finding Bengal tigers is most appealing. |
The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid --- we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.
However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard（蜥蜴）native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we'll need huge feet that we could bring up to our ears in order to create adequate "hitting."
But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a "non-Newtonian" liquid that doesn't behave like normal water. Now if the surface of the water is hit hard enough, particles（粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.
Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink --- and take a shower afterward!
