Humans aren’t the only ones getting a buzz from coffee. Caffeine can improve memory among honeybees and lead to better pollination(授粉). According to a recent study published in the journal Science.

The study was conducted by a team of researchers at Newcastle University in the United Kingdom. They found that the nectar(花蜜) of some flowers, such as those from grapefruit and lemon plants, as well as certain coffee flowers, contains low doses of caffeine. To get bees to feed on these flowers, the team trained the insects to associate food with the smell of the flowers. They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine. After 24 hours, the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants.

Professor Geraldine Wright led the researchers. “Remembering floral traits (花部特征) is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are,” Wright said in a statement.

Improved memory led to the better pollination. That’s because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate. This also suggests that caffeine plays a role in improving the bees’ ability to search for food.

Researchers found that caffeine’s effect on the bee brain is similar to its effect on mammals. “The change is similar to that produced by caffeine in neurons (神经元)”associated with learning and memory in the rat brain,” Wright said.

Bee populations have declining since 2007. The dramatic drop in the insects’ numbers has serious effects for ecosystems and the farming industry. Bees are needed in the reproduction of crops and spreading wild flower species. Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers.

Far out in the lake was a large wooden platform on which stood an improbably high diving board — a kind of wooden Eiffel Tower. It was, I’m sure, the county’s tallest wooden structure and no one had ever been known to jump from it.

So it was quite a shock when our teacher, Mr. Milton, announced that he would dive off the high board that very afternoon.

Word of his questionable plan was already spreading through town as Mr. Milton swam out to the platform. He was just a tiny, stick figure when he got there but even from such a distance the high board seemed almost to touch the clouds. Once at the top, he paced the enormously long board, then took some deep breaths and finally stood at edge. He was going to do it.

Several hundred people had gathered at the shore to watch. Mr. Milton stood for quite a long time, then he raised his arms, took one massive bounce and launched himself into a perfect dive. It was beautiful. He fell with perfect style for what seemed minutes. The crowd fell silent. The only sound to be heard was the faint whistle of his body tearing through the air toward the water far, far below.

But about three quarters of the way down he seemed to have second thoughts and began suddenly to panic, waving his arms and legs like someone having a bad dream. When he was perhaps thirty feet above the water, he gave up on waving and spread his arms and legs wide, apparently hoping that it would somehow slow his fall.

It didn’t.

He hit the water at over six hundred miles an hour. The impact was so loud that it made birds fly out of their trees three miles away. I don’t think he entered the water at all. He just bounced off it, about fifteen feet back into the air. After that, he lay still on the surface, spinning like an autumn leaf.

He was brought to shore by two passing fishermen in a rowboat and placed on an old blanket where he spent the rest of the afternoon. Occasionally he accepted small sips of water, but otherwise was too shocked to speak. From head to toe, he was covered with deep red bruises.

... It was the best day of my life.

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.

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

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

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.

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.

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.
