In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decade has seen more and more forests disappearing and the globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable（可持续的）ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.
Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decade. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil, which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions（排放）and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.
【小题1】The traditional business model is harmful because of all the following EXCEPT that _________.

The insanely popular song from South Korean recording artist PSY has just become the most watched video on YouTube ever, gaining more than 808 million views on the popular media site.

The record was previously held by another pop heavyweight, Justin Bieber, whose song“Baby”had a little more than 804 million views at press time. PSY made the announcement early today.
Since its release，the song has outshone such other popular videos as Jennifer Lopez’s“On the Floor.”and Eminem’s“Love the Way You Lie”.
And in September，“Gangnam Style”also became the most liked video on YouTube，now with nearly 5.4 million thumbs up．
At the time of the announcement, the Guinness Book of World Records released a statement saying: “In years past it was unthinkable that something would be viewed a hundred million times, and now Gangnam Style has achieved more than twice this figure in just three months on YouTube. PSY，your certificate is waiting here at our office，come and pick it up any time!”
Despite its massive popularity, the video shows no signs of slowing down, and it even has a shot at becoming the first video to get more than one billion views.
If it maintains its current rate of around six million new views per day, “Gangnam Style”would be in line to break that record by the end of the year.
It has found its way to the tops of music charts in more than 30 countries, including the United Kingdom, Germany, France, Spain and Canada, while providing material for thousands of parody videos.
It became a staple in the 2012 presidential elections with the now ramous “Mitt Romney Style” video and was even used by the North Korean government in propaganda(宣传)films promoting their supreme leader. Meanwhile, such influential figures as President Obama, UN Secretary General Ban Ki-moon and Google Executive Chairman Eric Schmidt have all made mention of the hit song.
【小题1】Which of the following ranks second in views on YouTube?

Fish have different personalities which change as they experience life’s highs and lows．according to British biologists．
Researchers identified different“personalities” in their fish by observing the boldness or shyness of individuals，according to The Nature．Like people，some fish are very confident in the face of novelty(新奇事物)or conflict；while others are silent and fear．
The scientists selected particularly bold and shy rainbow trout，and tested whether they changed their outlook depending on what life threw at them．They arranged some fish to fight and others to  watch to  see how both the participants  and  observers  responded to victories  and defeats．Winning or losing a fight，or even watching fellow fish overcome the difficulties influenced the future behavior of the creatures studied in the lab．
The researchers made fish compete with much larger or smaller opponents．to ensure that they would win or lose their fights．These bold fish that won their fights tended to be even bolder when later presented with  a novel food  item；losing their fight caused them to be  much more cautious．
Fish also learn by watching others．Bold fish watching a shy fish exploring a mystery object were much more nervous when later given a novelty item for themselves．
Predictably，shy fish that won a fight also gained more confidence，but surprisingly，shy fish that lost their fights also grew bolder when exploring strange new food，Sneddon said，adding that this could be due to what she calls a“desperado effect”(亡命徒效应)．
The new research suggests that animals can gradually adapt their personalities．The results echo the effects that life experience can have on human．
【小题1】What does．the underlined word“creatures’’probably refer to?

In the computer age, most of us take a broadband（宽带）Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files（档案文件）download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs（郊区）, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.
Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纤电缆) promise to bring extremely fast Internet connections to more users.
Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (迹象), it may not be too long before an Internet connection simply follows you wherever you go.
【小题1】The underlined part “a catch” (in Paragraph 2) probably means “_____”.

D
KIDS in a Sudanese refugee camp raise a cloud of dust as they kick around a football. NBA superstar Traey Mc Grady watches from a distance before offering to buy the kids a grass patch for $1,000.
Perhaps he sees a Ronaldinho rising up out of the African soil. Or maybe he just wants to do something—anything—to give these children some hope. But he is told, politely, that grass is not what the kids need.
Mc Grady, 29, writes on his website that he traveled to Africa because he was tired of only reading about it in the news.“Who are the faces behind the statistics?” he said.“I need to see it for myself.” And he did. He stepped out of his beautiful house and flew to a place torn to bits by war and famine(饥荒). He slept in a tent. He talked with people who had suffered. And he swallowed his pride.
But no one should blame Mc Grady for wanting to buy the kids a patch of grass. Sport gave him a chance, so perhaps he thought it would do the same for the refugees.
Mc Grady was eyed by NBA scouts as a teenager and he didn’t bother going to college. Instead, he leaped right into the NBA. Since that move, basketball has given him a handsome living, but one very far removed from the lives of ordinary people. As Mc Grady would learn in Africa, most people see sport as just a break from life’s difficulties. They don’t mistake it for life itself. Only Mc Grady knows how the trip to Africa changed him, but I’d bet that, at the very least, it has given him a new sense for what is truly meaningful.
Mc Grady doesn’t own an NBA championship ring. He hasn’t risen to the heights of Kobe Bryant or Michael Jordan. But, perhaps, now he knows he doesn’t have to in order to truly make a difference in the world.
63.The refugee children most probably need______.
A.clean drinking water           B.a grass football patch
C.necessities of survival          D.a tent to sleep in
64.What can we learn about Mc Grady from the passage?
A.Basketball made him what he is today.
B.He is an NBA superstar as great as Kobe or Jordan.
C.He didn’t show his talent for basketball as a teenager.
D.He taught children to play football in a refugee camp.
65.What does the underlined part “scouts” in Paragraph 5 probably mean?
A.players.      B.fans.         C.audience.       D.hunters.
66.Mc Grady learned from his visit to Africa that______.
A.he needn’t improve his basketball skills to reach the heights of his seniors
B.sport gave him a chance and means everything to him
C.people in hunger can never understand the importance of sport
D.what’s truly meaningful can be a world of difference to different people
