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, 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'd 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(微粒) 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!Walking on water hasn't become a reality mainly because humans _______.

As the sound of footsteps behind her grew louder, she quickened her pace. She didn’t want to turn around as the memory of that morning’s newspaper headline made her afraid of what she would see: “City Killer Claims Fourth Victim.”
“Why did I stop for a few drinks in the bar after work?” she thought to herself. Now it was dark and the streets deserted. She was alone and a sitting duck.
She felt as if she was walking in the rain. Her clothes were damp from nervous sweat and as each short hot breath hit the night air, it turned to steam, coating her glasses in a thin film so all she saw seemed covered in fog.
The footsteps were closer now. She needed to get off this street. Her eyes began a useless search for an open store or lighted window. Passing a small lane she looked through, for a possible escape route. But the lane was a dead - end and she laughed to herself at the irony ( 具有讽刺意味的事 ).
The sound of a car behind her turning onto the street interrupted her self – pity. Escape was at hand. But as she was about to throw herself onto the road and shout for the car to stop, the car’s headlights cast a shadow that paralyzed ( 使瘫痪 ) her with terror.
It was the footsteps’ owner. The figure was huge and in its raised arm it held what looked like a lead-pipe, no doubt the one that was about to claim victim number five.
The shadow dissolved as the car passed by and disappeared into the distance. She felt a hand on her shoulder. It was all happening as if in slow – motion. She was waiting for her life to flash before her eyes like all those novels said it would – but it didn’t. The only thing she thought of was her dear husband. She recalled phoning him from work that very afternoon and joking about, of all things, the city killer. It was a night full of ironies.
There was a voice talking to her now but she was lost in thoughts of her fate and didn’t respond. The hand then began turning her around. It was surprisingly gentle given what was about to come. She allowed it to guide her without resistance ( 抗拒 ).
She looked up. She recognized the face, but she didn’t know from where. Its mouth was still talking to her but she couldn’t understand. Then she remembered. The face belonged to the foreign looking man who had served her at the bar. She looked down to his hand and saw in it not a lead – pipe but a rolled up copy of a work report she had been correcting in the bar as she drank.
His words suddenly started to register in her brain and she could hear him. “Miss, Miss. Are you OK? You left this in the bar and it looked important so I thought I’d better give it to you.”

1685 was a very good year for German composers. Within the space of a month, two of the greatest were born: Johann Sebastian Bach and George Frideric Handel.
Handel’s father was a barber and surgeon, which sounds like a strange combination today, but back then those occupations went hand in hand. Even though Handel was very interested in music, his father didn’t think that was a good way to earn a living, so he wanted his son to be a lawyer. The story goes that Handel smuggled a quiet piano into the house so that he could practice in secret.
One day, Handel went along when his father went to shave a duke. While his father was working, Handel sat down and played the duke’s organ. The duke was so impressed that he convinced Handel’s father to let his son study music, and Handel finally got to learn how to compose.
Handel soon discovered that what he liked most was opera. In fact, he was so passionate about opera that he even fought a duel (决斗) over it with one of his friends. Since Italy was the place to learn about opera composing, Handel went off to Italy to study. When he got home, he got a job as court composer for a German prince.
Having landed such a wonderful job, Handel immediately asked his boss for time off. He wanted to go to England, where he’d heard that there weren’t nearly enough composers to satisfy the British taste for Italian opera.
After great success writing opera in London, Handel came back to Germany. Then fate played a funny trick on Handel and his boss. The Queen of England died, and it just so happened that the prince Handel worked for was next in line to the British throne ( 王位 ). When he arrived in London as King George, followed Handel, his court composer in Germany.
In addition to serving the King, Handel became one of the most successful opera composers of his time. And he also produced them and traveled all over Europe to hire the best singers. There are stories of battles with rival ( 对手 )opera producers and of fights between rival singers. Handel apparently had quite a temper.
If you ever go to London, look for Handel’s grave in Westminster Abbey, where there’s a wonderful monument to him.

I began to grow up that winter night when my parents and I were returning from my aunt’s house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.
I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see—the strange and magical places I had known only from books and pictures. The country I was leaving and never to come back was hardly in my head then.
The four years that followed taught me the importance of optimism, but the idea did not come to me at once. For the first two years in New York I was really lost—having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex for me. Some time passed before my stepfather and I got used to each other. I was often sad, and saw no end to “the hard times. ”
My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.
From my experiences I have learned one important rule: Almost all common troubles eventually go away! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy.

Parking has long been a major headache for drivers in Shanghai. The Transportation Department is mapping out a new plan for the city’s parking system. There are one million cars on the road in Shanghai but only enough public parking space to provide room for 15 percent of these vehicles. It is no wonder that local drivers get so worried trying to find a place to park.
The city is seeing a rise in private car owners. In March, the city sent out 2,000 private car licenses, the highest number of licenses ever sent out in a month. And prices rose to 14,600 yuan, 500 more than in February. Industry experts say this suggests that local people have a strong, active interest in buying cars.
By the year 2020, the number of automobiles in Shanghai will probably reach two million. If one parking lot is for each car, then a lot of parking space should be built for these vehicles.
Downtown Shanghai is most short of parking space. However, experts point out that simply building more parking lots in downtown areas is not practical and doesn’t provide an ideal solution. The idea of “ Park & Ride” system has been suggested. This means that drivers can leave their vehicles in car parks nearby subway or bus stations and ride public transport to go downtown. Based on this idea, the city will limit the number of parking lots in downtown areas and demand higher parking fees but build more parking areas near main subway and bus stops.
72.The underlined phrase “ mapping out ” in the first paragraph means __________.
A. making B. arguingC. controllingD. inspiring
73. About __________ drivers can find places to park their cars in Shanghai now.
A. 850,000 B. 1,000,000C. 150,000D. 2,000,000
74. What does the second paragraph mainly tell us ?
A. The city sent out more private licenses in February.
B. Less and less people bought cars in March.
C. The city sent out less private licenses in March.
D. More and more people are going to buy cars.
75. According to the idea of a “ Park & Ride ” system, the city will __________.
A. send out more private car licenses
B. build more parking lots near bus stops
C. encourage people to buy more cars
D. build more parking areas in downtown
When you take a walk in any city, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reason why people keep a dog has changed. In the old days people used to train dogs to protect(保护) themselves against attacks by other beasts. Later they came to realize that a dog was not only useful for protection but willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without permission.
These days people in the city need not protect themselves against attacks from animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery(抢劫). But the most important reason is for companionship. For a child, a dog is a best friend when there are no friends to play with. For young couples, a dog is their child when they have no children. For old couples, a dog is also their child when their natural children have grown up. So the main reason why people keep dogs has changed from protection to friendship.
