The summer of 2012 was full of reports of extreme weather: one of the warmest years on record in the US, the wettest summer in the UK, and the worst drought (旱灾) in East Africa. In short, extreme weather seems to be becoming the new normal. Weather extremes are not that extreme any more. Heatwaves, droughts and wildfires are the new reality of a warming world.
And this should not come as a surprise. Scientists have been warning for years that as the planet heats up, we will have to deal with more dreadful weather. Although not every extreme weather event is the result of climate change, scientists are now much more confident about connecting weather events with climate change. In 2011, the UK had a warm November. Researchers say that it was at least 60 times more likely to happen because of climate change than because of natural changes in the earth’s weather systems.
All the news shows that climate breakdown is occurring faster than most climate scientists had expected. But isn’t it too expensive to stop the climate from changing? Well, yes it costs. So everything is just as usual. It would be wrong to believe that to let things continue as they always do is the cheap choice. Instead, it is very expensive. Just one example: droughts in the US, Russia and the Ukraine sent food prices to a record high. According to the World Bank, the price for corn increased by 113% in some markets in Mozambique and in Sudan. This is the kind of cost that often gets ignored.
I believe intelligent climate action can help create new opportunities for jobs in Europe, for encouraging creativity and competitiveness, for spending less money on energy.According to the passage, in 2012 _____.
| A．the UK had a warm November | B．the US had many wildfires |
| C．the UK had a dry summer | D．East Africa had little rain |

| A．show a lot of people are hungry |
| B．prove food prices are very changeable |
| C．prove we’re paying for extreme weather |

| B．Europe is providing limited job opportunities. |
| C．It’s everyone’s duty to protect the environment. |
| D．Everyone needs time to get used to extreme weather. |
How words came into being is unknown.All we assume is that some early men invented cortain sounds,in one way or another,to express thoughts and feelings,actions and things,so that they could talk with each other.Later they agreed upon certain signs,called letters,which could be put together to show those sounds,and which could be written down.Those sounds,whether spoken or written in letters,are called words.
The power of words,then,lies in their associations-the things they bring up to our minds.Words become filled with meaning for us by experience;and the longer we live,the more certain words bring back to us the happy and sad events of our past;and the more we read and learn,the more the number of words that mean something to us increases.
Great writers are those who not only have great thoughts but also express these thoughts in words which have powerful effects on our minds and feelings.This clever use of words is what we call literary style.Above all,the real poet is a master of words.He can express his meaning in words which sing like music,and which by their position and association can move men to tears.We should therefore learn to choose our words carefully and use then correctly,or they will make our speech silly and common.We learn from the text that language might have begun with________.
| A．expressions |
| B．actions |
| C．signs |
| D．sounds |

The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms.
After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.
Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.
"The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometers per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots.
Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available.
The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.
Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advance warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said. The phrase "communications blackout" in paragraph 1 most probably refers to _______during the 2012 Olympics.
| A．the extinguishing of the Olympic torch |
| B．the collapse of broadcasting systems |
| C．the transportation breakdown in London |
| D．the destruction of weather satellites |
What can be inferred about the solar activity described in the passage?
| A．The most fatal matter from the corona falls onto Earth. |
| B．The solar storm peak occurs in the middle of each cycle. |
| C．It takes several seconds for the charged matter to reach Earth. |
| D．The number of sunspots declines after coronal mass ejections. |
According to the passage, NASA will launch a satellite to _________.
| A．take images of the solar system |
| B．provide early warning of thunderstorms |
| C．keep track of solar activities |
| D．improve the communications on Earth |
Which of the following might be the best title of the passage?
| A．Solar Storms: An Invisible Killer |
| B．Solar Storms: Earth Environment in Danger |
| C．Solar Storms: Threatening the Human Race |
| D．Solar Storms: Human Activities to Be Troubled |

About twenty of us had been fortunate enough to receive invitations to a film-studio(影棚)to take part in a crowd-scene. Although our "act" would last only for a short time, we could see quite a number of interesting things.
We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie-camera was wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in "snow". Two more fans were turned on, and a "strong wind" blew through the trees. The picture looked so real that it made us feel cold.
The next scene was a complete contrast (对比). The way it was filmed was quite unusual. Pictures taken on an island in the Pacific were shown on a glass screen (幕). An actor and actress stood in front of the scene so that they looked as if they were at the water's edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio!
Since it was our turn next, we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film "stars"! Who is the author?
| A．A cameraman. |
| B．A film director. |
| C．A crowd-scene actor. |
| D．A workman for scene setting. |
What made the author feel cold?
| A．The heavy snowfall. |
| B．The man-made scene. |
| C．The low temperature. |
| D．The film being shown. |
What would happen in the "three minutes" mentioned in the last paragraph?
| A．A new scene would be filmed. |
| B．More stars would act in the film. |
| C．The author would leave the studio. |
| D．The next scene would be prepared. |
Everyone becomes a little more forgetful as they get older, but men's minds decline more than women's, according to the results of a worldwide survey.
Certain differences seem to be inherent in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning and spatial skills), while women tend to excel (擅长) at recalling information from their brain's files (helpful with language skills and remembering the locations of objects).
Many studies have looked for a connection between sex and the amount of mental decline (衰退) people experience as they age, but the results have been mixed.
Some studies found more age-related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline. Those results could be improper because the studies involved older people, and women live longer than men: The men tested are the survivors, "so they're the ones that may not have shown such cognitive decline," said study team leader Elizabeth of the University of Warwick in England.
People surveyed completed four tasks that tested sex-related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category (范畴) as possible in the given time, e.g. "object usually colored gray", and recalling the location of objects in a line drawing. The first two were tasks at which men usually excel; the latter are typically dominated by women.
Within each age group studied, men and women performed better in their separate categories on average. And though performance declined with age for both genders, women showed obviously less decline than men overall. The underlined word in the second paragraph means_________.
| A．natural |
| B．great |
| C．obvious |
| D．absolute |
Which of the following statements is true according the article?
| A．Men do better than women when it comes to learning English. |
| B．Women stand out at remembering people’s names. |
| C．Men excel at typing as many words in a particular category as possible in the given time. |
| D．Women excel at dealing mathematic problems. |
One important factor that affects the correctness of the results is that _________.
| A．the old men tested may not have shown such cognitive decline |
| B．people surveyed are all old |
| C．people taking part in this test came from all over the world |
| D．women live longer than men |
The author aims to tell us that __________.
| A．women’s minds perform better than men’s |
| B．men’s minds decline more with age |
| C．everyone becomes a little more forgetful as they get older |
| D．a survey on human’s mind decline was done recently |
