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.

Farmer John and Farmer Bob were neighbours. For more than 30 years, they had been getting along very well.
Then their good relationship broke. It began with a small thing, then bitter words, and then weeks of silence. One morning Farmer John woke up to find a stream between the two farms. “It must be Bob,” John thought.
Then one day there was a knock on John’s door. He opened it to find a carpenter(木匠) standing at the doorway.
“I’m looking for a few days’ work,” the carpenter said.
“I do have a job for you,” John said. “Look across the stream at that farm. That’s my neighbour Bob. He dug a stream between the two farms. I want you to build a fence—an 8-foot fence. I don’t want to see his place or his face any more. I don’t have such a neighbour!”
The carpenter said, “I think I know what to do, sir, and I’ll be able to do a job that pleases you.”
Farmer John helped the carpenter get the materials(材料) ready and then he was off for the day.
About sunset when the farmer returned, the carpenter had just finished his job. The farmer’s eyes opened wide. There was no fence there at all!
It was a bridge! And the neighbour, Bob, was coming across, with his hand outstretched(伸出). “Hi, John! You’re quite a fellow to build this bridge!”
Then they met in the middle, taking each other’s hands. “I’m terribly sorry for what I have said and done. We should be good to each other.” said Farmer Bob.
Then they turned to see the carpenter, who was ready to go. “No, wait! Stay a few days. I have a lot of other jobs for you,” said Farmer John. “I’d love to stay,” the carpenter said, “but I have more bridges to build.”Just before the carpenter came, John and Bob each other.

Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a “territory” is ? A territory is an area that an animal , usually the male , claims as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and your friends are welcome. If a stranger should enter your territory and threaten you, you might shout, Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost anytime, especially at nesting season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs. You can see that birds have a language of all their own . Most of it has to do with attracting mates and setting up territories.Some scientists believe that most of the time birds’ singing is actually_____.

| B．Because their singing helps frighten outsiders away. |
| C．Because they want to find outsiders around. |
| D．Because their singing helps get rid of their fears. |
Fading beauty
She is widely seen as proof that good looks can last for ever. But, at nearly 500 years of age, time is catching up with the Mona Lisa.
The health of the famous picture, painted by Leonardo Da Vinci in 1505, is getting worse by the year, according to the Louvre Museum (卢浮宫博物馆) where it is housed.
“The thin, wooden panel on which the Mona Lisa is painted in oil has changed shape since experts checked it two years ago,” the museum said. Visitors have noticed changes but repairing the world’s most famous painting is not easy. Experts are not sure about the materials the Italian artist used and their current chemical state (状态).
Nearly 6 million people go to see the Mona Lisa every year, many attracted by the mystery of her smile. “It is very interesting that when you’re not looking at her, she seems to be smiling, and then you look at her and she stops,” said Professor Margaret Livingstone of Harvard University. “It’s because direct vision (视觉) is excellent at picking up detail, but less suited to looking at shadows. Da Vinci painted the smile in shadows.”
However, the actual history of the Mona Lisa is just as mysterious as the smile. Da Vinci himself loved it so much that he always carried it with him, until it was eventually sold to France’s King Francis I in 1519.
In 1911, the painting was stolen from the Louvre by a former employee, who took it out of the museum hidden under his coat. He said he planned to return it to Italy. The painting was sent back to France two years later.
During World War II, French hid the painting in small towns to keep it out of the hands of German forces.
Like many old ladies, the Mona Lisa has some interesting stories to tell.What does the writer mean by “time is catching up with the Mona Lisa”?
| A．The painted woman is not so beautiful any more. |
| B．Ageing is something that affects us all. |
| C．The painting needs repairing. |
| D．At such an old age, she is no longer popular. |
What makes the repair work difficult?
| A．The wooden panel is thin and old. |
| B．No one knows exactly what materials were used to create the painting and how it might respond to treatment. |
| C．The health of the painting is suffering |
| D．Experts can’t agree on how to carry out repairs. |
What makes her smile so mysterious according to Professor Livingston?
| A．The materials the Italian artist used. | B．The way she smiles. |
| C．The way Da Vinci painted the smile. | D．It plays a trick upon the human mind. |
Every year thousands of tourists visit Pompeii, Italy. They see the sights that Pompeii is famous for ― its stadium (露天大型运动场) and theatres, its shops and restaurants. The tourists do not, however, see Pompeii’s people. They do not see them because Pompeii has no people. No one has lived in Pompeii for almost 2000 years. Once, Pompeii was a busy city of 22000 people. It lay at the foot of Mount Vesuvius, a grass-covered volcano . Mount Vesuvius had not erupted for centuries, so the people of Pompeii felt safe. But they were not.
In August of AD 79, Mount Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ash began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.
For centuries, Pompeii lay buried under stone and ash. Then, in the year 1861, an Italian scientist named Ginseppe began to uncover Pompeii. Slowly, carefully, Ginseppe and his men dug. The city looked almost the same as it had looked in AD 79. There were streets and fountains（喷泉）, houses and shops. There was a stadium with 20000 seats. Perhaps the most important of all, there were everyday objects, which tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue colour in the bottom, so we know that the people of Pompeii liked wine. They liked bread, too; metal bread pans were in every bakery. In one bakery there were 81 round, flat loaves of bread ― a type of bread that is still sold in Italy today. Tiny boxes filled with a dark, shiny powder tell us that women liked to wear eye makeup.
Ginseppe has died, but his work continues. One-fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii.Why do large numbers of people come to Pompeii each year?
| A．To visit the volcano | B．To shop and eat there |
| C．To watch sports and plays | D．To watch how Pompeiians lived |
Why had so many Pompeiians remained by volcanic Mount Vesuvius?
| A．The city nearby offered all kinds of fun. |
| B．The area produced the finest wine in Italy. |
| C．Few people expected the volcano to erupt again. |
| D．The mountain was beautiful and covered with grass. |
Why did the city uncovered look almost the same as it had looked in AD 79?
| A．Because Ginseppe and his men dug it slowly and carefully. |
| B．Because the city was buried alive and remained untouched. |
| C．Because scientists successfully rebuilt the city with everyday objects. |
| D．Because nobody had lived in the city ever since the volcano erupted. |
What do we know about the Pompeiians who lived 2000 years ago?
| A．They lived more or less the same as Italians now do. |
| B．They liked women wearing all kinds of makeup. |
| C．They enjoyed a good life with drinking and eating. |
| D．They went back to Pompeii after the eruption in AD 79. |
