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 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 . 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... 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

"Have you ever heard the old saying, "Never judge a book by its cover"? This is a good rule to follow when you try to judge the cleverness of others by their looks and performance. Some people have minds that shine only in certain situations. A young man with an unusual gift in novel writing may find himself speechless before a pretty girl. But don't make the mistake of thinking he might not be that clever. With a pen and paper, he can tell what he thought very well. Other people may fool you into mistakenly thinking they are clever by putting up a good front. A student who listens carefully and takes notes in class is sure to make a good impression on his teachers. But when it comes to exams, he may get scores much lower than his classmates. We may conclude that:you can't judge someone by appearances. The only way to tell whether a person is clever or not is to get to know him by observing how he reacts to different situations. The more situations you observe, the more accurate your judgement is likely to be. So take your time. Don't judge the book by its cover. The best title for this passage is _ A) Judging cleverness B) Choosing a book C) A speechless young man D) Putting up a good front

History is full of cases where dreams have been a pathway to creativity and discovery.A striking example is provided by Dr.Otto Loewi,a pharmacologist and winner of a Nobel Prize.Loewi had spent years studying the chemical transmission of nerve impulses .A tremendous breakthrough in his research came when he dreamed of an experiment three nights in a row.The first two nights he woke up and wrote down the experiment quickly and untidily on paper.But the next morning,he couldn't tell what the notes meant.On the third night,he got up after having the dream.This time,instead of making notes he went straight to his laboratory and performed the crucial experiment.Loewi later said that if the experiment had occurred to him while awake he would have rejected it. Loewi's experiment gives some insight into using dreams to produce creative solutions.Inhibitions are reduced during dreaming,which may be especially useful in solving problems that require a fresh point of view. Being able to take advantage of dreams for problem solving is improved if you "set" yourself before retiring.Before you go to bed,try to think intently about a problem you wish to solve.Bury yourself in the problem by stating it clearly and reviewing all relevant information.Then use the suggestions listed in the previous section to catch your dreams.Although this method is not guaranteed to produce a novel solution or a new insight,it is certain to be an adventure.About half of a group of college students using the method for a week recalled a dream that helped them solve a personal problem. The main idea of this passage is that _ . A) very little is really known about the meaning of dreams B) it is possible to "catch" one's dreams by planning before going to sleep C) dreams can be useful in producing creative solutions to one's problems D) Loewi's experiment helped in the study of transmision of nerve impulses
