PROBLEM: Article: 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 insulation(, ) 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.
Question: What may probably be the best title of this passage?
Options: (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

SOLUTION: D

PROBLEM: Article: My husband and I were once in Nepal to see sunrise over the Himalayas. One morning we awoke to total darkness at 5 o'clock.As we rushed through a town with cameras in hand,I noticed the calm,gentle way the Nepalese people greeted the morning.One man boiled a huge pot of milk tea,and other villagers gathered around his fire,cupping their hands around small glasses of the steaming sweet mixture.It was fascinating,but not to be left behind,we joined the stream of tourists moving quickly up to the lookout point. The top was crowded when we arrived,but after 10 minutes of cold waiting,the assembled group gave up."The cloud cover is too heavy,"one said.Then one by one they rushed down the hill to the next item on their sightseeing list.I was disappointed as well,but suddenly I noticed a small Nepalese boy absently playing with a stick and shooting quick glances at the clouds.He must know something we don't,I thought.I decided to wait with him. The boy and I didn't have to wait long.Moments later,a tiny stream of golden light burned through one thick cloud,then another.Rose-colored fog warmed the backs of the clouds,and suddenly the morning sun stole a glance around the side of the mountain,mile above where I'd expected it to be. Nothing I'd seen before prepared me for the moment the clouds withdrew with bowed heads,and the magnificent Himalayas were revealed before,around,and above me.I sat in astonishment,not breathing,not daring to look away,certain that God had placed me here at the backdoor of Earth to show me what Heaven really looks like.I certainly got the message.Never again will I rush a sunrise.I now know Nature will supply her fruits to me only when I am truly ready to receive them.

Audio books do not just tell stories--they also provide language lessons.Imagine learning to speak a number of key Japanese phrases while you do the ironing,or learning basic French while doing the housework.Audio books can be found in most big bookstores,as well as over the Internet.There are books for people of all ages,including kids.If you are a member of a local library,you will also find audio books to borrow,so you can try one and decide if you really want to buy one.
