Everyone likes living in a clean and comfortable environment. If the envionment(环境) are bad, it will affect（影响）our body, and make us not feel well. Sometimes we may be terribly ill. At that time we don’t want to work, and we have to stay in bed and rest at home. So the envrionment is very important to us.
It’s germs that makes us ill. There are germs everywhere, They are very small and you can’t find them with your own eyes, but you can see them with a microscope（显微镜）They are very small and there may be hundreds of them on a very small thing, Germs can always be found in dirty water. When we look at dirty water under the microscope, we shall see them in it. Germs can also be found in air and dust（灰尘）. If you cut your finger, some of the dust from the floor may go into it, and you will have much pain in it. Sometimes the germs will go into all of your boby, and you will have pain everywhere.
To keep us healthy, we should try to our best to make our environment become cleaner and tidier. This needs us to act together.

This winter, the air quality over the north China plain was so bad that it was actually off the standard scale. The air pollution reached levels that the World Health Organization describes as dangerous. On Thursday, heavy smog blanketed most of northern and eastern China again.
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.
小题1:The writer mentions the heavy smog in parts of China in Paragraph1 in order to_____.| 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 | | D．highlight the importance of government’s policies and regulations |
小题2:Why is it a big challenge for the government to say “no” to the air polluting offenders in China?| A．Because enterprises are encouraged to develop economy at the cost of the environment. | | B．Because much emphasis has been laid on economic growth regardless of the cost. | | C．Because it’s impossible to relocate the enterprises for lack of money. | | D．Because the production capacity of enterprises falls behind the required speed. |
小题3:It can be learned from the passage that the essential reason for the worsening air conditions in China is_______.| A．the sharp growth of coal consumption in recent years | | B．the rapid increase of motor vehicles in cities | | C．the building of power plants in northern China | | D．the poor weather conditions caused by complex geographical factors |
小题4:According to the writer, which of the following is the key to solving the air pollution problem?| A．Giving priority to economic development in policymaking. | | B．Making environment-friendly policies and carrying them out effectively. | | C．Increasing investment in the construction of coal-fired facilities. | | D．Limiting the use of cars not meeting the required emission standard |
小题5:Which best describes the writer’s tone in the passage?| A．Pessimistic. | B．Convincing. | C．Doubtful. | D．Concerned. |

There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another product out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn’t going to rush an iPhone release simply to put it on shelves, he said.
“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 |
小题2:As for the next iPhone, Colin Gibbs didn’t mention ______.| 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 |
小题3:What’s Colin Gibbs’ attitude towards the next iPhone?| A．Disapproving. | B．Indifferent (漠不关心的). | C．Doubtful. | D．Objective. |
小题4:This passage is presented in the form of ______.| A．stories | B．comments | C．advertisements | D．debates |

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally.
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 |
小题2:What is the problem with using hydrogen as energy?| 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. |
小题3:Why does the author give the example in the last but one paragraph ?| 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. |
小题4:What is the author’s attitude about the future?| A．skeptical | B．negative | C．indifferent | D．positive |
小题5:What is the passage mainly about?| A．war and energy | B．the future of hydrogen as an energy resource | | C．the disadvantages of oil | D．How to end war |

The UK has a well-respected higher education system and some of the top universities and research institutions in the world. But to those who are new to it all, sometimes it can be confusing.
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 |
小题2:Why does the author suggest having wine glasses and snacks handy?| 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. |
小题3:The main purpose of the passage is to _______.| 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 |
