In “Relax, We’ll Be Fine”, columnist David Brooks writes, “the fact is, despite all the problems, America’s future is extremly bright.”
Mr. Brooks acknowledges that “According to recent survey, 60 percent of Americans think the country is heading in the wrong direction. The same percentage believe that the U.S. is in long-term decline. The political system is not functional. A financial crisis looks unavoidable. There are plenty of reasons to be sad.”
But, he writes:
“Demographers(人口学家) predict that over the next 40 years, the U.S. population will increase by an additional 100 million people, to 400 million over all. The population will be determined, hardworking and relatively young. In 2050, only a quarter will be over 60, compared with 31 percent in China and 41 percent in Japan.”
As the rising generation leads an economic recovery, it will also participate in a communal
(of community) one. We are living in a global age of social entrepreneurship(创业精神).
In sum, the U.S. is on the edge of a demographic, economic and social recovery, built on its historic strengths. The U.S. has always been good at destructive change. And it’s always been good at decentralized community-building, too. Surely a country with this much going for it is not going to wait around passively and let a rotten political culture drag it down.

Did you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of “grey matter” and “white matter”. While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes. As white matter is the key to spatial（空间的） tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for direction and women often need to!
The differences begin when fetuses（胎儿） are about nine weeks old, which can be seen in the action of children as young as one. A boy would try to climb a barrier before him or push it down while a girl would attract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.
If all this disappoints you, it shouldn’t. “The brain changes throughout our lives according to what we do with it.” says a biologist.The passage mainly tells us ________.
| A．the difference between men’s and women’s brains |
| B．the changes in brain throughout our lives |

Nelson Mandela is respected and admired across the world. And to South Africans he is a superstar. He is a hero who shocked the world by fighting for peace between races, despite the 27 years he spent in the prison of the South Africa’s white, racist regime(政权).
Mandela who won the nation’s first all-race elections after the fall of apartheid (种族隔离) in 1994, retired 1999.
But he remains as popular as ever.
“He’s loved by all people, whether you’re white or black, whether you’re young or old,” said Ali Bacher, South

on some goods. His face has appeared on a South African coin, a metropolitan area was named in his honour and
some business leaders hope to build a massive, rotating statue in his likeness --- the Statue of Freedom. It would
stand taller than New York’s Statue of Liberty.
His popular appeal is similar to that of John F. Kennedy with US or Winston Churchill in Britain, but few
politicians in this times have achieved his level of admiration, said Tom Lodge, head of the political science
department of the University of the Witwatersrand.
“Sometimes it isn’t completely appreciated what a skilled performer Mandela has been throughout his political
career. He’s a very, very clever man.” However, he is far from perfect.
Most articles for his birthday, which appeared in every major South African newspaper on the day, brief
mentioned that Mandela did have his shortcomings.
Then they returned to their flowing praises.
“Through the ages, the human race has had its icons (偶像) --- men and women who rose above ordinary people

On Nov.18th, 1908, three men went up in a balloon. They started early in London. The headman was Augusta Gaudron, and the other two men were Tannar and Maitland. They had a big balloon and they were ready for a long way.
Soon they heard the sea. They were carrying the usual rope, and it was hanging down from the basket of the balloon. At the end of the rope they had tied a metal box. This could hold water, or it could be empty. So they were able to change its weight. It was for use over the sea. They were also carrying some bags of sand.
After the sun rose, the balloon went higher. It went up to 3,000 meters, and the air was very cold. The water in the balloon became ice. Snow fell past the men's basket, and they could see more snow on the ground. The men tried to throw out some more sand, but it was hard. They tried to break the icy sand with their knives, but it was not easy. The work was slow and they were still falling, so they had to drop some whole bags of sand. One of them fell on an icy lake and made a black hole in the ice.
At last they pulled the box into the basket. It was still snowing; so they climbed up to get away from the snow. They rose to 5,100 meters! Everything became icy. They were so cold that they decided to land. They came down in Poland heavily but safely. They had travelled 1,797 kilometers from London!The metal box was used for ________.
| A．carrying the bags of sand |
| B．keeping drinking-water |

Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.
At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins. The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.Christian Eijkman went to the island of Java to ______.
| A．help the Javanese with their illness |

If a person doesn’t get enough vitamins in his diet, he’d better ______.
| A．eat more rice | B．eat vitamin pills |
| C．eat some chicken | D．eat more meat |
We can learn from the passage that ______.
| A．Christian Eijkman’s experiment was successful |
| B．the Javanese didn’t like vitamins |
| C．beri-beri was caused by chickens |
| D．the Javanese’s disease was caused by a kind of germ |
You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created Lampbrella, a lamp post with its own rain－sensing umbrella.
The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞篷)built into a street lamp，” he said.
The Lampbrella is a standard－looking street lamp fitted with an umbrella canopy. It has a built－in electric motor which can open or close the umbrella on demand. Sensors(传感器)then ensure that the umbrella offers pedestrians(行人)shelter whenever it starts raining.
In addition to the rain sensor, there's also a 360° motion sensor on the fiberglass street lamp which detects whether anyone is using the Lampbrella.After three minutes of not being used the canopy is closed.
According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each Lampbrella would offer enough shelter for several people. Being installed(安装) at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.
While there are no plans to take the Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.For what purpose did Belyaev create the Lampbrella?
| A．To protect people from the rain. |
| B．To predict a heavy rain. |
| C．To check the weather forecast. |
| D．To remind people to take an umbrella. |
What do we know from Belyaev's words in Paragraph 2?
| A．It rains a lot in the city of Saint Petersburg. |
| B．His creation was inspired by an experience. |
| C．Street lamps are protected by canopies. |
| D．He enjoyed taking walks in the rain. |
What does Paragraph 5 mainly tell us about the Lampbrella?
| A．Its moving speed. | B．Its appearance. |
| C．Its safety. | D．Its installation. |
What can be inferred from the last paragraph?
| A．The designer will open a company to promote his product. |
| B．The Lampbrella could be put into immediate production. |
| C．The designer is confident that his creation is practical. |
| D．The Lampbrella would be put on show in Moscow. |
