HOW many of you have used rock, paper, scissors (RPS) as a “fair” way to settle something? If you think it is a game of chance, think again, according to scientists.
RPS is a game as popular in the East as it is in the West. The rules are the same: Two players make one of the three hand signs. To decide the winner, rock breaks scissors, scissors cut paper, and paper covers rock.
Many of us play with no game plan in mind. But researchers have worked out several winning patterns. The World Rock Paper Scissors Society holds tournaments (联赛) in Toronto, Canada. According to their data, players choose rock (35.4 percent) and paper (35 percent) more than scissors (29.6 percent).
If your opponent is a man or an angry person, it’s quite possible they will start the game with rock, researchers have found. If your opponent is a woman or a beginner, you should expect them to start with scissors.
Earlier this year, Chinese scientists asked 360 students to compete in a RPS tournament at Zhejiang University. Scientists found that winners tend to choose the same action they won with, while the loser tends to change to the next action in the order of rock, scissors, paper.This is called the “win-stay lose-change” strategy(策略). Humans use this strategy in many competitive situations.
Expert RPS players have many other techniques. Monica Martinez, 2008 winner of the World RPS Tournament, said that she read faces.“I didn’t worry about what I was going to do, I just did what I thought they were going to do,” she told The Telegraph. If your friends are similar experts, learn from Jonathan Monaco, winner of the 2009 USA RPS Tournament. He wears dark sunglasses to cover his expressions during the game.
Remember, the strategy for playing RPS depends on how skilled your opponent is. But if you’re looking for a quick, simple winning rule for a match, choose paper. Scissors is the least popular choice, and men favor rock. Both are reasons to choose paper.

My House
My mother moved a lot when she was growing up on account of Grandpa being in the army. She hated having to adjust to new schools and make new friends. That’s why I thought she was joking when she put forward the idea of moving. But she was completely serious. “For just the two of us,” my mother said, “an apartment in the city will suit our needs much better.” Personally, I think she’s lost her mind. I guess I can understand why she would want to move, but what about me and what this house means to me?
I suppose if you looked at my house, you might think it was just another country house. But to me it is anything but standard. I moved into this house with my parents ten years ago. I can still remember that first day like it was yesterday. The first thing I noticed was the big front yard. To me it seemed like an ocean of grass—I couldn’t wait to dive in. The backyard was full of gnarled (扭曲的, 粗糙的) and scary trees that talk on windy nights. But I grew to like them and the shadows they cast in my room. My father and I even built a small tree house, where I often go to remember all the wonderful times we had before Father’s death.
This house is special—maybe only to me—but special nevertheless. It’s the little seemingly insignificant things that make this house so special to me: the ice-cold tile floors that make me tremble on midnight snack runs; the smell of my father’s pipe that still exists; the towering bookcases of my mother; the view outside my bedroom window.
This house holds too many memories, memories which would be lost if we gave it up.

Mary and Peter were having a picnic with some friends near a river when Mary noticed an object overhead. "Look!" she shouted to her friends. "That's a spaceship up there and it's going to land here."
Frightened by the strange silver-colored spaceship, most of the young people got in their cars and drove away quickly. Peter was fond of Mary and always stayed close to her. They, more curious than frightened, watched the spaceship land and saw a door open. When nobody came out, they went to the spaceship and entered inside. Peter followed Mary into the spaceship and did not hear the door closed behind him. The temperature fell rapidly and the two young people lost consciousness.
When they woke up, they were surprised to see that they were back by the river again. The spaceship had gone. Their car was nearby.
"What happened?" asked Mary.
Peter scratched (抓) his head, saying slowly, "Don't ask me. Perhaps we had a dream. Did you...Did you see a spaceship?"
"Yes," said Mary. "And we both went into it. Then..." she looked at her wrist. "That's funny. My watch has stopped. Oh, well, come on. It's time to go home."
Driving about fifty meters, they found their way blocked by a thick wall made of something like glass. They got out of the car and tried to find their way round the wall but discovered that they were inside a circular wall. It was like a mirror and prevented them from seeing through it.
On the other side of the wall, strange creatures walked past slowly. A few stopped to stare through the wall and read a new notice which, translated into English, said: "New arrivals at the zoo: a pair of Earthlings in their natural surroundings with their mobile house."

The announcements by the NASA, in the form of several Web site postings and a video posted on You Tube, were in response to worries that the world will end on Dec. 21,2012.
The doomsday(末日) rumour reached a high point with the release of the new movie “2012”, directed by Roland Emmerich. In the movie, Yellowstone blows up, showering the continent with black ash. Tidal waves wah over the Himalayas, where the governments of the planet have secretly built a ship which a select 400,000 people can ride out the storm. There are hundreds of books devoted to 2012, and millions of Web sites, depending on what combination of “2012” and “doomsday” you type into Google. All of it, astronomers say, is nonsense. “Most of what’s claimed for 2012 relies on wishful thinking and ignorance of astronomy.” Ed Krupp, an expert on ancient astronomy, wrote in an article in the November issue of Sky & Telescope.
“I get angry at the way people are being influenced and frightened to make money.” Morrison said. “There is no right to frighten children to make a buck.” Suggested David Morrison, an astronomer at the NASA Ames Research Center in Moffett Field, Calif. He said he had been getting about 20 letters and e – mail messages a day from people as far away as India scared out of their wits. Morrison said he did not blame the movie for all this, as much as many other supporters of the Mayan prediction .but then, he said, “my doctorate is in astronomy, not psychology.”
In an e – mail exchange, Krupp said: “We are always uncertain about the future, and we always consume representations of it. We are always attracted by the romance of the ancient past.” A NASA spokesman, Dwayne Brown, said the agency did not comment on movies, leaving that to movie critics. But when it comets to science, brown said, “we felt it was careful to provide a resource.”
If you want to worry, most scientists say, you should think about global climate change or nuclear war. But if ancient prophecies (预言) get you going, here are some things Morrison and the others think you should know.

Although we already know a great deal about flu, and although the World Health Organization is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be.
There are three kinds of flu virus, known as A, B and C. flu C virus is relatively stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies（抗体）which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability（可变性）is less developed in the flu B virus, which affects only human beings. As flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918&1919, when about half the world’s population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence（病毒性）, the ease with which it can be transmitted and the strength of the opposition it encounters（遇到）. Scientists, however, have a reliable general picture of the world situation.
1．hich of the following is the most appropriate title for the passage?
A．Symptoms of Flu B．Man Vs Flu Virus
C．WHO: The Major Organization against Flu Virus D．Variability of Flu Virus
2．hat does the author say about the flu B virus?
A．B Virus is relatively stable and causes mild infections that do not spread far through the population.
B．B Virus is unstable, and is responsible for the epidemics that cause frequent concern.
C．B virus is extremely unstable and is responsible for some of the worst outbreaks of the disease.
D．B virus has a very developed variability, and it affects only human beings.
3Which of the following is NOT mentioned as a factor contributing to the extent to which a virus spreads?
A．The strength of the virus.
B．The ease with which the virus can be transmitted.
C．The strength of the opposition.
D．The immunity the virus can bring about.
4．his article is quite probably ________.
A．a piece of news B．a special science report
C．an introduction to a disease D．a scientific fiction
