It is reasonable to ask why the air pollution is so bad this winter. Weather conditions and topographic(地形学的) factors have been given as reasons, but, although contributing factors, these are not to blame. The worsening air pollution is linked to an energy mix that relies heavily on coal and to motor vehicle emissions(排放). But despite the astonishing growth of motor vehicles in our cities, it is the burning of coal that is the biggest cause of air pollution. More than half of the country"s power plants are located in the eastern region and China"s coal consumption has more than doubled in the past decade, reaching 3.8 billion tons last year, accounting for almost half the world"s total coal consumption. And with coal occupying nearly 70 percent of the country"s primary energy consumption, it has become critical to reduce the use of coal if we are to solve the nation"s overall air pollution problem.
In the face of the poisonous air recently, one citizen said, "we have nothing but hot air to purify the skies". In fact, the government plans to have 350 billion yuan ($55.67 billion) investment in improving coal-fired facilities and limiting the use of yellow-label cars that do not meet the Euro I emissions standard and so on.
However, it would be far more effective to reduce emissions at the source, which means that the biggest challenge currently facing government departments is saying "no" to the country"s air polluting offenders. According to the Joint Prevention and Control Plan on Air Pollution in Key Regions released recently by the State Council, the amount of coal the nation consumes is set to rise by 30 percent during the period of the 12th Five-Year Plan. This is not going to let anyone breathe easier.
This highlights a key problem when it comes to environmental issues in this country - economic development comes first. The fundamental cause of the worsening air pollution is the idea of economic growth at any cost, which has resulted in ever-worsening pollution. And the priority(优先权)given to economic growth presents another problem, namely the failure of existing environmental protection policies and regulations to control pollution. For instance, the current weak regulations covering emissions would suggest there has been a significant reduction in emissions when clearly this is not the case. Also those enterprises found breaking the regulations are still far lower than the cost of treating the pollution they produce. This means even if many large-scale enterprises with lagging production capacity(能力) fail to meet the requirements for environmental protection, the environmental protection department is incapable of shutting these enterprises down or forcing their relocation.
Dealing with air pollution requires taking action at the local level to reduce vehicle emissions and at the regional level to reduce industrial emissions. But it also requires giving more priority to environmental issues in policymaking. Our hope is that the environmental protection department will be truly capable of saying "no" to pollution, and it will raise standards and effectively enforce them, and that governments at all levels will prioritize quality of life not just economic growth.

A.remind people to stay in doors because of the bad air quality |
B.show people’s concern about the priority to economic growth |
C.introduce the issue about the serious air pollution |

解析
试题分析:
本文介绍了中国空气污染的情况,分析了造成污染的原因,提出解决污染问题的对策措施。造成污染的原因主要是燃煤和汽车排放,燃煤是最大原因;而根源却在于“经济发展优先”的观念。作者指出,各级政府应该将人们的生活质量放在首位。
小题1:主旨大意题。文章主要分析污染原因,提出问题对策,第一段只是为了引起人们对污染的严重程度的关注,引起下文。故答案为C.
小题2:由第四段…which means that the biggest challenge currently facing government departments is saying "no" to the country"s air polluting offenders, ,“十二五”期间煤消耗增长30%到第五段第一句话“突显了一个关键问题,即‘经济发展优先’”可知,经济发展优先的观念阻碍了从根源上减少排放。故答案为B。
小题3:由第二段it is the burning of coal that is the biggest cause of air pollution一句可知,燃煤是造成污染越来越严重的根本原因。故选择A项。
小题4:污染越来越严重,燃煤是原因,但是根源却在于“经济发展优先”的观念。所以解决污染问题的关键在于改变观念。这就要求政府制定环保政策并有效实施。由最后一段But it also requires giving more priority to environmental issues in policymaking.可知B项正确。
小题5:作者对于环境污染越来越严重感到深深的忧虑。从最后一段故答案为D.

“If you’re Tim Cook (CEO of Apple), you’re thinking if you want to pay more attention to how to keep growing that bottom line and keep investors(投资人) happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time, and I’m having a hard time buying this May or June timeline.” Llamas told Mac News World.
While it’s probable that Apple is surely in a testing stage for its next smartphone, consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro.
“It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it’s possible that Apple could launch the next iPhone this spring or summer, I’m not expecting to see it until a little later in the year,” he told Mac News World.
When it does launch, though, it could be in a variety of colors, said Gibbs. “Apple has already tested the waters with releasing colored products when it revamped (更新,翻新)its iPod line last fall, so it is understood that it would want the new change with its smartphone, as well”.
“I wouldn’t be surprised if the new iPhone becomes available in some new colors,’’ he said. “That could be done pretty cheaply, and it would give Apple a new marketing angle.”
小题1:According to Ramon Llamas, Apple always ______.
A.tries to please its investors |
B.rushes to put new products to market |
C.ignores the fierce market competition |
D.does things as planned |
A.the stage of its being tested |
B.the rough time of its being released |
C.the function to be improved |
D.the wide variety of its color |
A.Disapproving. | B.Indifferent (漠不关心的). | C.Doubtful. | D.Objective. |
A.stories | B.comments | C.advertisements | D.debates |
Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed.
Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen “fuel cells” for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars.
The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth’s population that has no electricity.
And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night.
Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web,” which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.
Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race.
小题1:What does the underlined word “it” in the last but one paragraph refer to?
A.wealth | B.hydrogen | C.electricity | D.fuel |
A.It has by-products. |
B.It has to be separated from other materials. |
C.It will make energy too cheap. |
D.It is too far away from us. |
A.To tell us that we produce energy while using hydrogen power. |
B.To tell us that hydrogen power does not produce pollution. |
C.To show hydrogen power can stop war. |
D.To show hydrogen power is cheap. |
A.skeptical | B.negative | C.indifferent | D.positive |
A.war and energy | B.the future of hydrogen as an energy resource |
C.the disadvantages of oil | D.How to end war |
October is usually the busiest month in the college calendar. Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends, join lots of clubs and settle into university life.
However, having just left the comfort of home and all your friends behind, the prospect (前景) of meeting lots of strangers in big halls can be nerve-wracking (令人焦虑不安的). Where do you start? Who should you make friends with? Which clubs should you join?
Luckily, there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.
Here are some top advice from past students on how to survive Freshers’ Week:
● Learn rules. Make sure you know British social etiquette (礼节). Have a few wine glasses and snacks handy for your housemates and friends.
● Be kind. Sometimes cups of tea or even slices of toast can give you a head start in making friends.
● Be sociable. The more active you are, the more likely you’ll be to meet new people than if you’re someone who never leaves his room.
● Bring a doorstop. Keep your door open when you’re in and that sends positive messages to your neighbors that you’re friendly.
So with a bit of clever planning and effort, Freshers’ Week can give you a great start to your university life and soon you’ll be passing on your experience to next year’s freshers.
小题1:We can learn from the passage that ______.
A.Freshers’ Week usually comes in September in UK |
B.all the students are required to join certain clubs in UK |
C.many freshers are worried about how to fit university life |
D.most of the students in the UK spend three years in universities |
A.To pass the busy university life. |
B.To help make friends with other freshers. |
C.To show yourself a drinker as others. |
D.To enjoy the time in a happy way. |
A.tell the newcomers how to make a new start in universities |
B.introduce something about higher education system of the UK |
C.inform the freshers of British social etiquette |
D.advise the freshmen how to behave well in the beginning |
In the mid 1990s external email providers appeared. The most famous of these was Hotmail, the first free email provider and webbased email service. Sabeer Bhatia and Jack Smith launched Hotmail on July 4, 1996. And Microsoft took note of and bought Hotmail for $400 million on December 30, 1997, a nice birthday present for Bhatia who turned 29 that day. It was relaunched as MSN Hotmail and in 2007 was relaunched again as Windows Live Hotmail.
Fast forward the present day and most of us have at least a personal webbased email account. It seems impossible to live without them. One of the biggest advantages of email is the fact that communication has become so much easier, especially with those across different time zones. Email takes seconds to send a message whereas letters, as we used to communicate by, could take weeks. Of course there was the fax, that beeping invention from the 1980s, but it wasn’t as secure as email and you never knew if the person on the other end had picked up your fax or if it had got lost somewhere in the office.
In conclusion, one of the best inventions from the 1990s has to be email. But sometimes people are too closely connected to their email and have a compulsion to check it several times a day. At work, people have become lazy and instead of going to speak to the person sitting next to them, they send an email,causing an in box to pile up with more time spent reading email and responding rather than working. Clearly, an invention that saved time because of its quick and speedy connection can now also cause us to waste a lot of time.
小题1:The earliest web-based email came into being probably _______.
A.in 1991 | B.in 1996 | C.in 1997 | D.in 2007 |
A.it is exactly as good as email |
B.it is much better than email |
C.it is less convenient than email |
D.it is easier and faster than email |
A.strong desire | B.common sense | C.special curiosity | D.general idea |
A.We should check email boxes frequently. |
B.Lazy people like sending an email. |
C.Email brings us great convenience. |
D.Good inventions also cause problems. |
What if Timothy spent thirteen hours a day at a sewing machine instead of a desk? We would immediately be shocked, because that would be called children being horribly mistreated. Timothy was far from being mistreated, but the mountain of homework he faced daily resulted in a similar consequence —he was being robbed of his childhood. In fact, Timothy had no time to do anything he truly enjoyed, such as playing video games, watching movies, or playing board games with his friends.
Play, however, is a crucial part of healthy child development. It affects children’s creativity, their social skills, and even their brain development. The absence of play, physical exercise, and freefrom social interaction takes a serious toll on many children. It can also cause significant health problems like childhood obesity, sleep problems and depression.
Experts in the field recommend the minutes children spend on their homework should be no more than ten times the number of their grade level. As a fifthgrader, Timothy should have no more than fifty minutes a day of homework (instead of three times that amount). Having an extra two hours an evening to play, relax, or see a friend would soundly benefit any child’s life quality.
小题1:What does the underlined word “them” in the first paragraph probably refer to?
A.Timothy’s parents. | B.Timothy’s grades. |
C.Psychologists. | D.The students. |
A.Timothy was very hardworking. |
B.Timothy was being mistreated. |
C.Timothy had a heavy burden. |
D.Timothy was enjoying his childhood. |
A.Children should be allowed enough time to play. |
B.Playing board games works better than playing video games. |
C.The more they play, the more creative children will become. |
D.The depression caused by homework makes children unwilling to play. |
A.About ten minutes. |
B.No more than twenty minutes. |
C.No more than thirty minutes. |
D.About fifty minutes. |
