Most respected scientists agree that we need to find another source of energy- and quickly. If we continue to burn oil and pump carbon into the atmosphere, then the effects on global climate will lead to global disasters even before the oil disappear.
The British government has set a target of a 20 percent reduction in carbon emission by 2010. Central to this policy is the search for alternative, renewable forms of energy production---and this is where the serious disagreement among scientists begins.
Here, two people active in the debate about wind farms give their points of view.
Simon Shearman
“First, a few facts about wind power. Wind is one of the cheapest of the new, renewable forms of energy. It is extremely safe---no member of the public has ever been injured at a wind farm. The shallow waters around Britain are the windiest in Europe---ideal locations for wind farms and, by 2010, up to ten percent of the electricity used in the UK could be produced by wind power. I find it annoying and frustrating that the biggest objection that opponents of wind farms can come up with is that the crisis of global warming is real and something must be done urgently.”
Alice Evans
“The simple, obvious fact is that wind turbines（涡轮机） cannot generate electricity if the wind is too light or too strong and it often is. Many scientists estimate that wind turbines generally produce only 30 percent of their capacity（容量）. This is not a reliable enough supply to enable us to close down conventional power stations. In fact, wind power can’t keep up with the growth of the demand for electricity, let alone replace other sources of power.”
It’s a topic that is causing heated debate around the country---but one we must address before it’s too late---before the oil runs out.Many scientists have different opinions on the search for a renewable energy because ______.
| A．they think fossil fuels are everlasting. |
| B．British government’s target is not realistic. |
| C．they are not sure in finding the clean and renewable energy. |
| D．the technology is not advanced enough. |
We can learn from the passage that ______.
| A．there won’t be a global disaster before the world runs out of oil. |
| B．the British government wants people to use 20 percent less oil by 2010. |
| C．Alice Evans supports the idea of wind power. |
| D．Simon Shearman thinks Britain a particularly suitable place for wind farms. |
If we generate electricity with wind turbines, _______.
| A．a light wind will do. |
| B．we cannot make full use of the capacity. |
| C．a strong wind will do |
| D．we’ll have enough electricity. |
What can we learn from the last paragraph?
| A．Wind power is a good solution to energy crisis. |
| B．We’re experiencing the oil crisis now. |
| C．We should find alternative energy for oil as soon as possible. |
| D．There is no need for us to worry about energy problem. |
Sometimes just when we need the power of miracles to change our beliefs， they materialize in the places we’d least expect. They can come to us as a drastic alteration in our physical reality or as a simple synchronicity in our lives. Sometimes they’re big and can’t be missed Other times they’re so subtle that if we aren’t aware， we may miss them altogether. They can come from the lips of a stranger we suddenly and mysteriously encounter at just the right instant. If we listen carefully, we’ll always hear the right words，at the right time， to dazzle us into a realization of something that we may have failed to notice only moments before.
On a cold January afternoon in 1989，I was hiking up the trail that leads to the top of Egypt’s Mt. Horeb. I’d spent the day at St. Catherine’s Monastery and wanted to get to the peak by sunset to see the valley below. As I was winding up the narrow path，I’d occasionally see other hikers who were coming down from a day on the mountain. While they would generally pass with simply a nod or a greeting in another language，there was one man that day who did neither.
I saw him coming from the last switchback on the trail that led to the backside of the mountain. As he got closer，I could see that he was dressed differently from the other hikers I’d seen. Rather than the high-tech fabrics and styles that had been the norm，this man was wearing traditional Egyptian clothing. He wore a tattered， rust-colored galabia and obviously old and thick-soled sandals that were covered in dust. What made his appearance so odd，though，was that the man didn’t even appear to be Egyptian！ He was a small-framed Asian man, had very little hair，and was wearing round，wire-rimmed glasses.
As we neared one another，I was the first to speak.“Hello，”I said，stopping on the trail for a moment to catch my breath. Not a sound came from the man as he walked closer. I thought that maybe he hadn’t heard me or the wind had carried my voice away from him in another direction. Suddenly he stopped directly in front of me on the high side of the trail， looked up from the ground， and spoke a single sentence to me in English，“Sometimes you don’t know what you have lost until you’ve lost it.”As I took in what I had just heard，he simply stepped around me and continued his descent down the trail.
That moment in my life was a small miracle. The reason is less about what the man said and more about the timing and the context. The year was 1989，and the Cold War was drawing to a close. What the man on the trail couldn’t have known is that it was during my Egyptian pilgrimage， and specifically during my hike to the top of Moses’s mountain，that I’d set the time aside to make decisions that would affect my career in the defense industry，my friends，my family，and，ultimately，my life.
I had to ask myself what the chances were of an Asian man dressed in an Egyptian galabia coming down from the top of this historic mountain just when I was walking up，stopping before me，and offering his wisdom，seemingly from out of nowhere. My answer to my own question was easy： the odds were slim to none！ In an encounter that lasted less than two minutes on a mountain halfway around the world from my home， a total stranger had brought clarity， and the hint of a warning， regarding the huge changes that I would make within a matter of days. In my way of thinking，that’s a miracle.
I suspect that we all experience small miracles in our lives every day. Sometimes we have the wisdom and the courage to recognize them for what they are. In the moments when we don’t，that’s okay as well. It seems that our miracles have a way of coming back to us again and again. And each time they do，they become a little less subtle，until we can’t possibly miss the message that they bring to our lives！
The key is that they’re everywhere and occur every day for different reasons， in response to the different needs that we may have in the moment. Our job may be less about questioning the extraordinary things that happen in our daily lives and more about accepting the gifts they bring.Why did the author make a pilgrimage to Mt. Horeb in Egypt?

Scientists from the United States say they have found fish and other creatures living under key waters in Antarctica. They made the announcement after completing three months of research at the Ross Ice Shelf, the world’s largest floating ice sheet.
The researchers hoped to find clues to explain the force of the melting ice and its effect on sea level rise. Reed Scherer and Ross Powell are with Northern Illinois University in DeKalb, Illinois. They just finished up their research on our southernmost continent. Money for the project came from America’s National Science Foundation.
“We chose a study site where, in the first year ,We went into the subglacial (冰川下的)lake and tried to understand the environment in there, both ecologically and in terms of the ice dynamics about how the lake operates ,and how the sediment(沉淀物) underneath the ice sheet operates, as well, because it’s the water and the sediment underneath the ice that controls how fast the ice is flowing into the ocean” says Ross Powell, who led the investigation. The team included scientists ,engineers, machinery and other supplies across the ice from the main U.S. scientific base at Mc Murdo Station to the researcher’s camp .The camp was near a subglacial lake ,where an earlier study took place,
Ross Powell says the latest study may provide evidence that can help predict the effect of climate change on rising sea levels.
“What we have found is that these are very sensitive areas to the stability of how dynamic the ice is and how fast the ice may react to increases of melting both from the ocean and the atmosphere.”
Among the new instruments built for the project was a powerful hot water drill. The researchers used the drill to dig down some 740 meters. They collected water ,sediment and other material from the grounding zone.
Working around the clock before the deep hole refroze, they sent a video camera down to the 400-square-meter undersea area.
Reed Scherer says the video images they saw in the Command Center were a total surprise.
“It’s a very mobile environment. The bottom is changing constantly. And so the things that we saw were all very mobile organisms, things that swim and some things that crawl. And obviously they are getting enough nutrition that they can thrive, Some of the little crustacean-like creatures called amphipods that we saw swam quite quickly and were quite active.”
This is the farthest south that fish have ever been seen. How did the creatures get here? What do they feed on? And what effect will the retreating ice have on them?
Ross Powell says the ice and sediment cores taken from the grounding zone can offer clues.
“We know that the ice is melting there at the moment and so by opening up the cores once they get back, we hope to be able to understand what the ice was doing in the past ,relative to what it is doing now. And because it is melting so fast or seems to be melting fast at the moment, we anticipate that there will he some differences that we’ll see in the history of the ice sheet from the sediment cores, once we open them up .”But Ross Powell says the work raises more questions than it answers.Scientists conducted the three-month research at the Ross Ice Shelf with the intention of .
| A．predicting how climate change influences rising sea levels. |
| B．finding out whether there are life forms existing deep under Antarctic ice. |
| C．proving the speed of ice flowing into the ocean is controlled by water. |
| D．discovering an explanation of the effect the melting ice has on sea level rise. |
What made the researchers surprised when they saw the video images?
| A．Researchers saw fish in the farthest south for the first time. |
| B．A video camera was able to work well under deep icy waters. |
| C．Sediment cores present differences in the history of the ice sheet. |
| D．The drill should dig down 740 meters to collect things. |
From sediment cores taken from the grounding zone, scientists will probably know.
| A．what the ice will do in the near future |
| B．the ice in the grounding zone is melting at the moment |
| C．some differences rarely exist in the history of the ice sheet |
| D．something about the creatures under icy water in Antarctic. |
What can be inferred from the passage?
| A．Scientists will conduct a follow-up study on the frozen continent. |
| B．No creatures once appeared or lived in icy water in Antarctica. |
| C．America’s National Science Foundation is in complete charge of the research. |
| D．Researchers have found how the sediment underneath the ice sheet operates. |
Lee Kuan Yew emerged onto the international stage as the founding father of the state of Singapore, then a city of about 1 million. He developed into a world statesman who acted as a kind of conscience to leaders around the globe.
Fate initially seemed not to have provided him with a stage on which to achieve more than modest local success. In the first phase of decolonization, Singapore emerged as a part of Malaya. It was cut loose because of tensions between Singapore’s largely Chinese population and the Malay majority and, above all, to teach the city a lesson of dependency, Malaya undoubtedly expected that reality would cure Singapore of its independent spirit.
But great men become such through visions beyond material calculations. Lee challenged conventional wisdom by opting for statehood. The choice reflected a deep faith in the virtues of his people. He asserted that a city located on a sandbar with no economic resource to draw upon, and whose major industry as a colonial naval base had disappeared, could nevertheless thrive and achieve international reputation by building on its principal asset(财富): the intelligence, industry and dedication of its people.
A great leader takes his or her society from where it is to where it has never been ---- indeed, where it as yet cannot imagine being. By insisting on quality education, by suppressing corruption and by basing governance on merit. Lee and his colleagues raised the annual per capita income of their population from $500 at the time of independence in 1965 to roughly $55,000 today. In a generation, Singapore became an international financial center., the leading intellectual metropolis of Southeast Asia, the location of the region’s major hospitals and a favored site for conferences on international affairs. It did so by adhering to an extraordinary pragmatism: by opening careers to the best talents and encouraging them to adopt the best practices from all over the world..
Superior performance was one component of that achievement. Superior leadership was even more important. As the decades went by, it was moving ---- and inspirational ---- to see Lee., the mayor of a medium-size city, become a mentor of global strategic order.
The great tragedy of Lee’s life was that his beloved wife was felled by a stroke that left her a prisoner in her body, unable to communicate or receive communication. Through all that time, Lee sat by her bedside in the evening reading to her. He had faith that she understood despite the evidence to the contrary.
Perhaps this was Lee Kuan Yew’s role in his era. He had the same hope for our world. He fought for its better instincts even when the evidence was ambiguous. But many of us heard him and will never forget him.Why did Lee Kuan Yew choose to lead Singapore to be independent?
| A．He intended to act as a kind of conscience to leaders around the globe. |
| B．He determined his people shouldn’t be subjected to Malaya anymore. |
| C．He had considerable confidence in the value of the city’s assets. |
| D．He wanted Singapore to be the most powerful country worldwide. |
From the underlined sentence in Paragraph2, we can know that ________.
| A．Malaya expected Singapore to be powerful |
| B．Malaya had a desire to kick off Singapore |
| C．Malaya firmly believed Singapore would give in |
| D．Malaya didn’t think Singapore possessed independent spirit |
The fourth paragraph is organized to ________.
| A．illustrate how advanced Singapore has been today |
| B．demonstrate Lee Kuan Yew attached great importance to the talents |
| C．prove what a crucial decision Lee Kuan Yew once made |
| D．show the tremendous impact Lee Kuan Yew had on Singapore |
Which of the following can best describe Lee Kuan Yew?
| A．Stubborn and arbitrary |
| B．Aggressive and affectionate. |
| C．Demanding and bossy |
| D．Outspoken and humorous. |

Indeed,” George Washington wrote in his diary in 1785, “some kind of fly, or bug, had begun to eat the leaves before I left home.” But the father of America was not the father of bug. When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century, and Americans had already created lightning-bug(萤火虫). But the English were soon to stop using the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries.
The American bug could also be a person, referring to someone who was crazy about a particular activity. Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs, and the like.
Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burglar alarm, from which comes the expression to bug, that is, “to install an alarm”. Now it means a small piece of equipment that people use for listening secret
ly to others’ conversation. Since the 1840s, to bug has long meant “to cheat”, and since the 1940s it has been annoying.
We also know the bug as a flaw in a computer program or other design. That meaning dates back to the time of Thomas Edison. In 1878 he explained bugs as “little problems and difficulties” that required months of study and labor to overcome in developing a successful product. In 1889 it was recorded that Edison “had been up the two previous nights discovering ‘a bug’ in his invented record player.” We learn from Paragraph 1 that __________________.
| A．Americans had difficulty in learning to use the word bug |
| B．George Washington was the first person to call an insect a bug |
| C．the word bug was still popularly used in English in the nineteenth century |
| D．both Englishman and Americans used the word bug in the eighteenth century |
What does the word “flaw” in the last paragraph probably mean?
| A．Explanation. | B．Finding. |
| C．Origin. | D．Fault. |
The passage is mainly concerned with__________________.
| A．the misunderstanding of the word bug |
| B．the development of the word bug |
| C．the public views of the word bug |
| D．the special characteristics of the word bug |
