Wikipedia (维基百科) is a non-profit website funded by donations, started on 15thJanuary, 2001. “Wiki” means “quick” in the Hawaiian language. These days, most people go straight to Wikipedia, the online encyclopedia (百科), to look something up. But how reliable is it?
The site attracts 78 million visitors every month, and it is available in more than 270 different languages. It’s one of the most comprehensive (综合的) resources available, and it’s got much more information than an ordinary encyclopedia. The site is updated on a daily basis by thousands of people around the world. Anyone with an Internet connection can look through and edit the contents or add a new page at any time. And you don’t need any formal training.
Of course, there are some controls. Wikipedia has a team of more than 1,500 administrators who check for false information. And main targets for horrible comments (such as politicians) are forbidden to public editing. But with more than 16 million articles to keep an eye on, it isn’t easy. So, while Wikipedia benefits from being constantly updated with information from all over the world, it’s also open to “vandals”(故意捣乱者).
Some of the damage is easy to notice. Someone drew horns and a moustache on Microsoft chairman Bill Gates’ photo. But other things are harder to spot. The most common form of vandalism involves adding tiny items of false information into the biography of a famous person. Unbelievably, some of this misinformation has appeared in newspapers, withThe Daily Mail, The GuardianandThe Independentall having fallen victim to the tricks. For example, in an obituary (讣告) for British comedian Sir Norman Wisdom, one newspaper claimed that he co-wrote Dame Vera Lynn’s wartime song “There’ll be Bluebirds over the White Cliffs of Dover”. In fact, he did no such thing.
So if you’re going to use any information from Wikipedia, make sure you double-check it first.What do we know about Wikipedia?

【原创】NOWADAYS, most animated (动画) films rely heavily on computer technology. But his magical world – where witches (魔法师) cast spells and castles float in the sky – is brought to life by hand. Nevertheless, Hayao Miyazaki is referred to as Japan’s Walt Disney and considered by many to be the world’s greatest living animator.
This month, the 72-year-old Miyazaki announced his retirement. The Japanese animator has directed 11 animated full-length films over the past four decades, including the Oscar-winning Spirited Away (《千与千寻》) and his latest release, The Wind Rises (《起风了》), which tells the life story of a man who designed Japanese World War II fighter planes.
Just as The Wind Rises shows, Miyazaki is well-known for his obsession with flight, especially human flight. Other striking aspects of Miyazaki’s films include his themes of environmental protection and the horrors of war.
Miyazaki’s work is also famous for its lack of clearly defined good and evil characters. He sees the 21st century as a complex time when old norms need to be re-examined.
As a storyteller, he is an inventor of fairy tales full of mystery. In the Miyazakian universe, wizards (巫师) turn into birds of prey; young girls are transformed overnight into 90-year-old women; greedy parents are changed into pigs; and shooting stars become fire demons (恶魔).
As a visual (视觉的) artist, most of Miyazaki’s grace comes from his vivid (鲜明的) colors and lovingly drawn landscapes – a rolling meadow (草地) covered with flowers and shadowed by clouds, or a range of rocky hills rising toward snow-capped mountain peaks
People attribute Miyazaki’s success to his long pursuit of his hand-drawn technique, although in an interview with CNN he called himself an “extinct species” in the age of digital animation.
A recent television documentary on the making of The Wind Rises showed a disappointed Miyazaki throwing a pile (堆) of drawings into the trash. He is said to have redrawn thousands of frames of the much-praised Princess Mononoke (《幽灵公主》) when they did not meet his standards.
But his huge attention to detail has earned him the respect of the entire animated film world. Even John Lasseter – head of Pixar, the famous US computer animation studio – once called Miyazaki “one of the greatest filmmakers of our time”.What can we know about Miyazaki’s film The Wind Rises?
| A．It was put on a long time ago. |
| B．Its hero is a soldier. |
| C．It describes horrors of war. |
| D．It is an Oscar-winning film. |
What does the underlined word “obsession” mean in paragraph 3? ?

Before he sailed round the world alone, Francis Chichester had already surprised his friends several times. He had tried to fly round the world but failed. That was in 1931.
The years passed. He gave up flying and began sailing. He enjoyed it greatly. Chichester was already 58 years old when he won the first solo transatlantic sailing race. His old dream of going round the world came back, but this time he would sail.His friends and doctors did not think he could do it, as he had lung cancer. But Chichester was determined to carry out his plan. In August 1966, at the age of nearly 65, an age when many men retire, he began the greatest voyage of his life.
Chichester covered 14100 miles before stopping in Sydney, Australia. This was more than twice the distance anyone had previously sailed alone. He arrived in Australia on 12 December, just 107 days out from England. He received a warm welcome from the Australians and from his family who had flown there to meet him. On shore, Chichester could not walk without help. Everybody said the same thing: he had done enough; he must not go any further. But he did not listen.
After resting in Sydney for a few weeks, Chichester set off once more in spite of his friends' attempts to dissuade him. The second half of his voyage was by far the more dangerous part, during which he sailed round the treacherous Cape Horn.After succeeding in sailing round Cape Horn, Chichester sent the following radio message to London: "I feel as if I had wakened from a nightmare. Wild horses could not drag me down to Cape Horn and that sinister Southern Ocean again."
Just before 9 o'clock on Sunday evening 28 May 1967, he arrived back in England, where a quarter of a million people were waiting to welcome him.Queen Elizabeth II knighted(授以爵位) him with the very sword that Queen Elizabeth I had used almost 400 years earlier to knight Sir Francis Drake after he had sailed round the world for the first time.The whole voyage from England and back had covered 28,500 miles. It had taken him nine months, of which the sailing time was 226 days. He had done what he wanted to accomplish.
What can we learn about Chichester?
| A．He failed the solo transatlantic sailing race in 1959. |
| B．He was a brave and determined man. |
| C．The second half of his voyage was not as dangerous as the first half. |
| D．The radio message expressed his concern about the sailing. |
【改编】What happened to Queen Elizabeth II after Chichester arrived back in England?
| A．She called on the English to learn form him. |
| B．She was waiting to congratulate on his success in sailing. |
| C．She thought little of his achievements. |
| D．She knighted him for praising him. |
【改编】What can we infer from the text ? ____
| A．Anyone who had sailed alone traveled less than 7050miles before 1966 |
| B．Chichester sailed round the Atlantic in 1931 |
| C．Most of the English leave their jobs at the age of 65 |

A new satellite is travelling 1.5 million kilometers over a 110-day period to enter an orbit of the sun. It is called DSCOVR--the Deep Space Climate Observatory. It will replace a satellite that has been observing space weather.
DSCOVR will begin its work during the worst of the 11-year-long solar cycle. This is a time when extreme weather on the sun can have the greatest effect on planet Earth.
DSCOVR will gather information about a continuing flow of particles from the sun. We are protected from these particles by the Earth's magnetic field and atmosphere. But we are not fully protected from what scientists call Coronal Mass Ejections. These are strong storms that can happen on the sun's surface.
Thomas Berger is the director of the Space Weather Prediction Center at the National Oceanic and Atmospheric Administration, or NOAA. He says these ejections are much more dangerous than solar particles. He says the Coronal Mass Ejections are extremely large magnetic clouds that are expelled from the sun at extremely high speeds. He says when they impact Earth, it is like a hurricane impacting Earth in terms of space weather.
Violent space weather can make electric systems stop working. It can block satellite signals to Earth. It can interfere with radio signals and air travel.
Mr. Berger says we cannot stop the ejections from affecting us, but we can prepare for them if we know when they will happen. When the DSCOVR satellite records an ejection, it will release a warning. Mr. Berger says the warning will provide NOAA about 15 to 60 minutes to let people know that a very strong storm is coming in to the Earth. He says that is enough time for power grid operators to take protective action. He says it is also enough time for workers to place satellites on a safe operating method if necessary.
Mr. Berger says scientists would like even more time, of course. He says researchers are developing instruments that will give an earlier warning.
The warnings from DSCOVR will be for the whole planet. But Mr. Berger says a new system may be able to give more-targeted warnings. He says future models will be able to tell exactly what part of the world will be more at risk from a solar storm.
That means that, for the first time, humans will get both a warning that a magnetic storm is heading towards Earth and information about where it is likely to hit.The new satellite is used to ________?
| A．replace the satellite in use |

According to Thomas Berger, __________?
| A．the Coronal Mass Ejections are expelled from the sun at extremely low speeds |
| B．the ejections can be stopped from affecting us |
| C．ejections are far more dangerous than solar particles |

Robots are common in today's world. They manufacture cars, work in space, explore oceans, clean up oil spills and investigate dangerous environments. And now, scientists at the University of Manchester are using a robot as a laboratory partner.
The researchers at the university created the robot in 2009 and named it Adam. Despite the name, Adam is not a humanoid robot. It is about the size of a car.
Adam was built to do science and make discoveries. Ross King is the leader of the University of Manchester research team. He says the robot made a discovery about yeast(酵母), a kind of fungus(真菌) used in science as a model for human cells.
"Adam hypothesized certain functions of genes within yeast and experimentally tested these hypothesizes and confirmed them. So it both hypothesized and confirmed new scientific knowledge."
Adam's success as a scientist led to the creation of another robot scientist named Eve. Researchers developed Eve to design and test drugs for tropical and neglected diseases. These diseases kill and infect millions of people each year.
Drug development is slow and costly. Experts say it can take more than 10 years and about $1 billion to discover and develop new medicines. Drug manufacturers are unlikely to get their investment money back.
So the University of Manchester developed a low-cost test that shows whether or not a chemical is likely to be made into an effective medicine. Mr. King says that other drug testing methods were not very effective.
"How it works conventionally is you use robotics as well and you have a large collection of possible drugs. You test every single compound. And you start at the beginning of your library and continue until the end, and stop. So it's not a very intelligent process. The robotics doesn't learn anything as it goes along, even if it's tested a million compounds, it still doesn't have any expectation of what will happen next when it tests a new compound."
Mr. King says that Eve is different because the robot learns as it tests different compounds. He says the robot is designed to ignore compounds that it thinks unlikely to be good. It will only test the compounds which have a good chance of working.
Eve has discovered that a compound known to be effective against cancer might also be used to fight against malaria and other tropical diseases.
Mr. King says he hopes to completely automate the drug testing process with robots like Eve to create and test new chemicals. But he says humans remain in control of the manufacturing process.Scientists now are using a robot to__________.
| A．manufacture cars |
| B．work in the laboratory |
| C．work in space |
| D．explore oceans |
Thepurposeofbuilding Adam is to________.
| A．do science and make discoveries |

Autism spectrum disorder is a developmental disability. People with autism have trouble communicating and with social skills. The U.S. Centers for Disease Control and Prevention says the person also might repeat some behaviors and not want change in their daily activities. Some people with the condition need a lot of help. Others need less.
CDC officials say autism affects one in every 68 children in the United States. More boys than girls are believed to have the condition. But the number of cases appears to be growing. It is unclear whether the growing number shows a real increase or comes from more knowledge about this disorder.
Symptoms of autism
Common signs of autism include trouble making eye contact and a delay in learning how to speak. Some people with severe autism never learn how to talk. Many people with autism also have difficulty understanding facial expressions and the feelings of others. They also have trouble making friends of the same age.
Doctors have learned how to recognize autism, but much is still unknown about its causes.
Researchers at Harvard University have come closer to finding answers. They found that women exposed to the highest levels of fine particulate air pollution late in their pregnancies are two times more likely to give birth to a child with autism. The findings appeared in Environmental Health Perspectives -- a publication of the National Institute of Environmental Health Sciences.
The study found that the women who were around high levels of fine particulate matter air pollution were at highest risk of having an autistic child. The increased risk of these women was two times that of women who lived in areas with low levels of fine particulate pollution.
The researchers found that the timing of exposure to pollution was important. They found no increased risk of autism in children whose mothers were around high levels of pollution before becoming pregnant. And the study found air pollution does not seem to increase the risk of children developing autism after they are born.
What can pregnant women do?
Mr. Weisskopf says pregnant women should avoid air pollution as much as possible. But he warns that other things may increase the risk of autism spectrum disorder.
"You can avoid being in extremely polluted cities during pregnancy if possible. You can also choose to go running in a park rather than next to a street. But that said, I think also it's very important to recognize that autism spectrum disorders is a very multi-factorial disorder. And there are lots of reasons why risk could be increased."
Autism is believed to result from a combination of environmental and genetic factors.
For now, Marc Weisskopf says researchers are trying to identify the exact substances in air pollution that increase the risk of autism.What can we learn from Paragraph 1________?
