One of my China Dialogue colleagues in Beijing recently bought a Philips energy-saving light bulb to replace a standard one．He was happy with his choice．It may have cost 30 yuan （just under US$4．50） - ten times the price of a filament （燈絲） bulb - but he wanted to save energy as part of his low-carbon lifestyle．And according to the shopkeeper, he would save, in the long run, much more than the 30 yuan he was spending．
Yet only one month later, his expensive light bulb blew up, before he had saved even a small part of the purchase price．Will he stick to his high-cost, low-carbon lifestyle?
China's environmental organizations have started to advocate low-carbon lifestyles and the decrease of carbon footprints to help fight against climate change．But they have overlooked one fact: in China, low-carbon living comes at a high cost．It means buying energy-saving bulbs and appliances, and environmentally friendly building materials and daily goods．Cost can no longer be the only standard for purchases．An energy-saving and environmentally friendly product is more expensive than a standard alternative - whether it's a simple light bulb or the house it shines．For average consumers, even buying an ordinary bulb is a huge burden．How can we persuade ordinary people to choose an energy-saving residence? This is not a trend they can afford to follow; perhaps this fashion is only for the rich．
Most consumers today do not cause huge carbon dioxide （CO₂） emissions．Their responsibility lies not in choosing a low-carbon lifestyle today, but in avoiding a high-carbon life in the future．The principle of "common but differentiated responsibility" - a basis of sustainable development - can be applied here as well．
In China, low-carbon living still is resisted by a lack of social infrastructure（基礎設施）. Even if your salary allows you to make that choice, nobody is there to help you accomplish it．
Consider energy-saving homes. You need to find out whether or not the developer has used natural materials wherever possible; how effective the insulation（絕緣物、隔熱物） is; and what the green credentials of installed equipment are．You can read up a little, but you'll still be lucky to avoid being puzzled by the developers' marketing．Many so-called energy-saving buildings are nothing of the sort, and some are even more energy-hungry than the average home - as Li Taige warned in his article "Energy-efficient buildings? Not always", on China Dialogue last August．
小題1: What may probably be the best title of this passage?

A．To purchase a cheap bulb - your wise alternative．

B．To choose an energy-saving residence - a must of your life

C．To learn a low-carbon lifestyle - each citizen's responsibility

D．To learn a low-carbon lifestyle - a promising but difficult purpose

小題2:Why does the writer say this fashion is only for the rich in the fourth paragraph?

A．Because the cost is a very important standard for purchases.

B．Because buying an ordinary bulb is very expensive.

C．Because energy-saving products are more expensive than the common alternatives.

D．Because rich people like to follow this trend.

小題3: What does the writer think of energy-saving homes?

A．Most of them are environmentally friendly.

B．They are musts of low-carbon lifestyle of Chinese.

C．They are huge burdens for Chinese people.

D．Many of them are more in name than in reality.

小題4:We can infer from the passage that ____．

A．Using energy-saving bulbs and appliances is a fashion．

B．It's easy for most Chinese to try to learn a low-carbon lifestyle．

C．All citizens in China don’t have the same responsibility in living a low-carbon lifestyle．

D．Most Chinese families cannot afford to purchase an energy-saving residence.

小題5:What is the writer's attitude towards the low-carbon lifestyle?

A．informative and entertaining	B．supportive but cautious
C．negative but wise	D．positive and active

小題1:D
小題2:C
小題3:D
小題4:C
小題5:B

試題分析：文章通過介紹作者朋友買節能燈泡的事，分析了在中國大范圍推廣低碳生活的局限性和不可行性，除此之外，他還給了讀者在選擇低碳住宅時的一些建議。
小題1:標題選擇題。根據文章大意，低碳生活雖然十分有益，但在我國現在的背景下實施起來十分困難，所以選D
小題2:細節題。根據同一段中的An energy-saving and environmentally friendly product is more expensive than a standard alternative，可知低碳設備比普通設備更貴，所以選C
小題3:細節題。根據最后一段Many so-called energy-saving buildings are nothing of the sort, and some are even more energy-hungry than the average home，可知作者認為低碳住宅許多都是名不副實，所以選D
小題4:主旨大意題。根據作者在文中所表達的主題和common but differentiated responsibility，可知國人依據不同的經濟狀況，責任也有所不同，所以選C
小題5:作者態度題。根據文章大意和作者的語氣可知對于低碳生活的態度是支持的，但他也有所保留，所以選B。

Is your family interested in buying a dog? A dog can be a pleasant companion（伙伴） to your family, but if you choose the wrong kind of dog，you will have a lot of troubles.
Families should sit down and thoroughly discuss the possible problems before buying a dog. Even if the children in your family are the ones who want the dog, the parents are the ones who are really responsible for seeing that the animal is properly cared for. If you don’t know much about dogs, it is a good idea to go to the library for books about different kinds of dogs, as well as books about how to train a young dog. In reading about the different breeds(種類)you should know that a dog described(描述)as very alert(機敏靈活的)may be too active. When a book describes a dog as an excellent hunting dog, it probably means that the dog won’t be happy living in a small house. Dog breeds vary(變化)in popularity as the years go by. One of the most popular dogs these days is the German shepherd（牧羊犬）. This is because it provides protection as well as companionship（陪伴）. The family should be warned that these dogs grow up to be very big, and may be too powerful for children to control. If space is limited, a toy dog may be a good choice. These dogs are very small and easy to train. They don’t need to be walked daily, since they can exercise in the home.
小題1:According to the passage, one can get information about different kinds of dogs .

A．by going to the library

B．by asking someone who has enough experience about different kinds of dogs

BEIJING—As China scrambles to respond to the choking smog that has blanketed Beijing in recent weeks, authorities in several major cities are experimenting with carbon trading platforms. The schemes are one effort to get control over greenhouse gases in an economy still hungry for cheap energy.
It has been a persistent concern in recent years, but the spiking pollution levels in January are sparking a public outcry.
Emissions from coal-fired electricity plants and busy factories are part of the problem that officials hope to get control over through carbon trading platforms. Seven cities are expected to open carbon markets later this year, including Tianjin.
“The government has decided to start with programs because the carbon trading is something new to China,” said David Tang, secretary of the board of the Tianjin Carbon Exchange. “So we want to have a number of programs to explore the use of the market.” said Tang.
China wants to launch a national carbon trading program by 2016. If it is successful, analysts say, the program would be one of the largest in the world and would help the country meet its target of cutting carbon dioxide emissions by 45 percent within seven years.
The platforms allow companies to earn credits for lowering greenhouse gas emissions, which can then be traded. If it works, it would encourage for-profit businesses to invest in green technology.
As public concern builds pressure for the government to find a solution, Wu Changhua, greater China director of the Climate Group, says there is a broad shift under way in how Chinese weigh their quality of life.
China has long put economic growth ahead of environmental concerns, making it the world’s biggest polluter. Carbon trading supporters hope that the markets could be one way to curb pollution and keep the economy growing.
小題1:Which of the following is TRUE about carbon trading platforms?

A．They are used to trade various resources.

B．They caused the choking smog in China.

C．They have been in existence for many years in China.

D．The choking smog may promote their development.

小題2:The underlined word in Paragraph 1 means “ ______”.

A．to make blanket

B．to cover something

C．to make something empty

D．to be like a blanket

小題3:Tang’s attitude towards carbon markets is ______.

A．unknown

B．indifferent

C．optimistic

D．pessimistic

小題4:What can we infer from the passage?

A．China will have built a national carbon trading program by 2016.

B．Chinese have lived a life of high quality in all aspects.

C．The markets could slow the development of economy.

D．Standards of life will be changed in China.

小題5:What's the main idea of this passage?

A．The choking smoke in China.	B．The urge for carbon trading platforms.
C．Greenhouse gases.	D．The world’s biggest polluter.

Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.
Diet products weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie（卡）, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the counter instead. All we have to do is to swallow or recognize the word “diet” in food brands.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(營養成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
小題1:The first paragraph mainly tells us _____.

A．diet products can bring out people’s potential

B．people have difficulty in choosing diet products

C．diet products are misleading people

D．people are fed up with diet products

小題2:One psychological effect of diet products is that people tend to ____.

A．resist a variety of diet foods

B．hesitate before they enjoy diet foods

C．pay attention to their own eating habits

D．watch their weight rather than their diet

小題3:The purpose of writing this passage is _________.

A．to warn people of the side effect of diet products

B．to tell people how to lose weight

C．to advise people to eat diet products

D．to introduce some diet products

小題4: Which of the following shows the structure（結構） of the passage?

CP: Central Point P: Point Sp: Sub-point(次要點) C: Conclusion

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(投資人) 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.”
小題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

小題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

小題3:What’s Colin Gibbs’ attitude towards the next iPhone?

A．Disapproving.

B．Indifferent (漠不關心的).

C．Doubtful.

D．Objective.

小題4:This passage is presented in the form of ______.

A．stories

B．comments

C．advertisements

D．debates

Graduation day is a major accomplishment for anyone in high school. After      your whole life in classrooms, though, what will be next? For some people, graduation is the        time they ever want to see a        again. For others, it is the next step in their education. And the few that are not       either way yet will most likely either go on to college or go into the military. There are always a few people in every        class that don't know what to do,        if you make a good choice, you will not be one of them.
Some of those people that decide that they never want to       a classroom again will most likely       some sort of simple jobs. Others will either find a way aside from school to better themselves,       through travel or giving back to the community.
High school graduates that already have their futures        0ut are pretty rare. They are the       who have been preparing for college from the first day that they         high school. They most likely applied early to the schools that they were interested       and have already dedicated themselves to the career        they want. Most of them will become doctors, lawyers, and business people, etc.
The last group of people is the biggest. It is the students who _     know that they want to do something but have no idea what. Some of them will _      the military and proudly serve our country. Others will go on t0       , take basic courses, and then decide what they want to major in. There will be some students even         to a technical school to learn a specific     that they can contribute to the workforce.        is a stepping stone that can lead you on to better things if you will let it.

Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. It has been shown that rats will, when given a choice over a period of time, prefer water with vitamins(維生素) to water without vitamins, even though there is no difference in taste or smell between the two water bottles. When a sweet smell was added to the vitamins-enriched water, the rats did seem to develop a taste for it and kept drinking it, even after the vitamins were changed to the clear water. In time(最后), however, they broke the habit and went back to where the necessary vitamins were.
In experiments, babies of 6 to 12 months old were placed in a room with many choices of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating habits, but over a period of time they managed to choose a well-balanced diet.
So in choosing food, rats and babies do seem to know what's best for them. Clearly, there is a kind of “body wisdom”, which humans soon lose. Most of us do not eat as wisely as we could. Many of our food preferences are culturally determined and influenced by old habits. Some people eat foxes, dogs and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seem to be greatly influenced by what is going around them.
小題1: In the experiment on rats, a sweet smell was added to the rats’ drinking water to ________ .

A．encourage rats to drink vitamins-enriched water

B．test whether rats know which drink is good for them

C．find out rats’ preference in flavor(口味)

D．show the vitamins are tasteless

小題2:Talking about eating habits, babies and rats are just like each other because ________ .

A．both have the wisdom to choose a balanced diet

B．both prefer flavored food and drink

C．both have the same eating habits

D．both develop a taste for the same kinds of food

小題3:In the experiment mentioned in the second paragraph, babies were ________ .

A．given many choices of drinks

B．placed and fed in a hospital

C．given all kinds of baby food

D．trained to select a balanced diet

小題4:Grown-up people’s eating habits differ from those of babies because ________ .

A．they know better than babies what kinds of food are good for their health

B．they usually cannot say no to all kinds of delicious foods

C．their eating habits have much to do with the social and cultural customs

D．they have more choices of food than babies in eating patterns

How to be Prepared
Electricity, water, gas and telephone may not be working after an earthquake. The police and fire department are likely to be tied up. You should be prepared to take care of yourself for at least three days, preferably for a week.
This list can also be applied to other disasters, such as floods or wildfires.

2. a first aid kit
3. a fire extinguisher suitable for all types of fires
4. flashlights, a portable radio extra batteries
5. blankets, clothes, shoes and money (ATMs may not work)
6. baby and pet food
It’s also a good idea to decide beforehand how and where your family will reunite if separated during a quake and to conduct in-home practice drills.
During an Earthquake
If you are indoors, stay there. Get under and hold onto a desk or table, or stand against an interior wall. Stay away from exterior walls, glass, heavy furniture, and stay away from windows and outside walls and do not use the elevator.

If you are driving, move the car out of traffic and stop, avoid parking under or on bridges or overpasses, Try to get clear of trees, light posts, signs and power lines.
If you are in a crowded public place, avoid panicking and do not rush for the exit. Stay low and cover your head and neck with your hands and arms.
After an Earthquake
If the phone is working, only use it in case of emergency. Likewise, avoid driving if possible to keep the streets clear for emergency vehicles.
Be aware that items may fall out of cupboards or closets when the door is opened, and also that chimneys can be weakened and fall with touch. Check for cracks and damage to the roof and foundation of your home.
