请阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

　　When do you become an adult, a grown－up? At eighteen? Twenty－one? Thirty? Adulthood(成年期)may seem a long way away to you, but the fact is that you are in the process of becoming an adult right now．The changes are so gradual that you may not notice them, but you can be sure that they’re happening．

　　When you were a child, a parent or older relative probably bought your clothes and helped you clean up your room．Now you are likely to have a clothes allowance(补贴), to care for your bedroom, and to share other cleaning chores(杂务)．You may once have had trouble getting your homework finished on time．By now, you may have learned to pace yourself．You know how much time you need．Do you remember begging your parents to stop for ice cream, or take an after－school job when you want money for a new clock radio? Of course, you don't always plan your time and your money perfectly．Your room doesn't always pass inspection．And you are often less than even tempered when something upsetting happens．But you’re learning．

　　As you get older, you have more privileges(特权)and more responsibilities(责任)．You may baby－sit for younger brothers and sisters, help cook dinner, and do odd jobs to contribute to the family income．You may get to stay up to watch a late movie on television, sit in on adult conversations, take subways and buses alone, or go on camping trips with your friends．Eventually, you will have a job and an apartment of your own．You'll become a voter and perhaps a husband or wife, maybe even a parent．But doing things adults do does not necessarily mean you will be wiser, braver, or more self－assured．It takes time to acquire knowledge and build self－confidence．Adults need to test themselves in the world, just as you do as a teenager．Being an adult is a continual process of growth．

(1)

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 （灯丝） 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（基础设施）. 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（绝缘物、隔热物） 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．
