ementary schools in this lakeside city at the southern tip of Lake Como. There are zero school buses.

In 2003, to confront the triple threats of childhood obesity, local traffic jams and — most important — a rise in global greenhouse gases abetted by car emissions, an environmental group here proposed a retro-radical concept: children should walk to school.

They set up a piedibus (literally foot-bus in Italian) — a bus route with a driver but no vehicle. Each morning a mix of paid staff members and parental volunteers in fluorescent yellow vests lead lines of walking students along Lecco? s twisting streets to the schools? gates, Pied Piper-style, stopping here and there as their flock expands.

At the Carducci School, 100 children, or more than half of the students, now take walking buses. Many of them were previously driven in cars. Giulio Greppi, a 9-year-old with shaggy blond hair, said he had been driven about a third of a mile each way until he started taking the piedibus. “I get to see my friends and we feel special because we know it? s good for the environment,” he said.

Although the routes are each generally less than a mile, the town? s piedibuses have so far eliminated more than 100,000 miles of car travel and, in principle, prevented thousands of tons of greenhouse gases from entering the air, Dario Pesenti, the town? s environment auditor, estimates.

The number of children who are driven to school over all is rising in the United States and Europe, experts on both continents say, making up a sizable chunk of transportation? s contribution to greenhouse-gas emissions. The “school run” made up 18 percent of car trips by urban residents of Britain last year, a national survey showed.

In 1969, 40 percent of students in the United States walked to school; in 2001, the most recent year data was collected, 13 percent did, according to the federal government? s National Household Travel Survey.

Lecco? s walking bus was the first in Italy, but hundreds have cropped up elsewhere in Europe and, more recently, in North America to combat the trend. Towns in France, Britain and elsewhere in Italy have created such routes, although few are as extensive and long-lasting as Lecco? s.

ne of Poland&39;s favorite native sons-Frédéric, Chopin.

The prestigious International Chopin Competition for pianists will mark its 16th edition in October 2010. Held every five years, the competition draws scores of young musicians from all over the world. In addition, Warsaw&39;s Chopin Museum, with the world&39;s largest collection of Chopin documents and other artifacts, will undergo a total redesign, modernization and expansion.

A lavishly illustrated new guidebook called "Chopin&39;s Poland" was already published this year. It leads visitors to dozens of sites in Warsaw and elsewhere around the country where the composer lived, ate, studied, performed, visited or even partied.

"Actually, Chopin doesn&39;t need to be promoted, but we hope that Poland and Polish culture can be promoted through Chopin," said Monika Strugala, who is coordinating the Chopin 2010 program under the aegis of the Fryderyk ChopinInstitute, a body set up by the Sejm in 2001 to promote and protect Chopin&39;s work and image.

"We want to confirm to all that he is a very, very important Polish symbol," she said. Indeed, it&39;s not much of an exaggeration to say that Chopin&39;s music flows through the Polish national consciousness like some sort of cultural lifeblood. The son of a Polish mother and a French émigréfather, Chopin was born in a manor house at Zelazowa Wola, about 50 kilometers, or 30 miles, west of Warsaw, and moved to Warsaw as an infant.

The manor is something of a Chopin shrine-since the 1930 s it has been a museum and center for concerts. Like the Chopin Museum in Warsaw, it, too, is undergoing extensive renovation as part of bicentennial preparations.

Chopin spent his first 20 years in and around Warsaw. He was already a noted pianist as a boy and composed concertos and other important works as a teenager. He carried Polish soil with him when he left Warsaw on a concert tour in 1830, just a few weeks before the outbreak of the November Uprising, an abortive Polish revolt against Czarist Russia, which then ruled Warsaw and a broad swath of Polish territory.

Chopin remained in exile in France after the uprising was crushed. But so attached was he to his native land that after his death in Paris in 1849 his heart-on his own instructions-was brought back to Warsaw for interment. The rest of his body is buried in the Père Lachaise cemetery in Paris.

"For where your treasure is, there your heart will be also,"reads the Biblical inscription on a plaque where his heart is kept today, preserved in an urn and concealed in a pillar of the Holy Cross Church in central Warsaw. Mozart&39;s"Requiem" will be performed here as part of Bicentennial events.

Exile and patriotism, as well as extraordinary genius, have long made Chopin&39;s appeal transcend all manner of social and political divides.

Polish folk motifs thread through some of his finest pieces, and patriotic fervor, as well as homesick longing, infuse some of his best-known works.

cientific opinion: The European Union should suspend its goal of having 10 percent of transportation fuel made from biofuel by 2020.

The European Union&39;s biofuel targets were increased and extended from 5.75 percent by 2010 to 10 percent by 2020 just last year. Still, Europe&39;s well-meaning rush to biofuels, the scientists concluded, had produced a slew of harmful ripple effects - from deforestation in Southeast Asia to higher prices for grains.

In a recommendation released last weekend, the 20-member panel, made up of some of Europe&39;s most distinguished climate scientists, called the 10 percent target "overambitious" and an "experiment" whose "unintended effects are difficult to predict and difficult to control."

"The idea was that we felt we needed to slow down, to analyze the issue carefully and then come back at the problem," Laszlo Somlyody, the panel&39;s chairman and a professor at the Budapest University of Technology and Economics, said in a telephone interview.

He said that part of the problem was that when it set the targets, the European Union was trying desperately to solve the problem of rising transportation emissions "in isolation," without adequately studying the effects of other sectors like land use and food supply.

"The starting point was correct: I&39;m happy that the European Union took the lead in cutting greenhouse gasses and we need to control traffic emissions," Somlyody said. "But the basic problem is it thought of transport alone, without considering all these other effects. And we don&39;t understand those very well yet." The panel&39;s advice is not binding and it is not clear whether the European Commission will follow the recommendation.

It has become increasingly clear that the global pursuit of biofuels - encouraged by a rash of targets and subsides in both Europe and the United States - has not produced the desired effect.

Investigations have shown, for example, rain forests and peat swamp are being cleared to make way for biofuel plantations, a process that produces more emissions than the biofuels can save. Equally concerning, land needed to produce food forpeople to eat is planted with more profitable biofuel crops, and water is diverted from the drinking supply.

In Europe and the United States, food prices for items like pizza and bread have increased significantly as grain stores shrink and wheat prices rise.

The price of wheat and rice are double those of a year ago, and corn is a third higher, the UN Food and Agriculture Organization said this week.

"Food price inflation hits the poor hardest, as the share of food in their total expenditures is much higher than that of wealthier populations," said Henri Josserand of the Food and Agriculture Organization

For example, the European Environment Agency advisory panel suggests that the best use of plant biomass is not for transport fuel but to heat homes and generate electricity.

To be useful for vehicles, plant matter must be distilled to a fuel and often transported long distances. To heat a home, it can often be used raw or with minimal processing, and moved just a short distance away.

中国是一个有5000年历史的文明古国，有着与外来文化取长补短、兼容并蓄的传统。我们的祖先历来强调“以和为贵”。历史上，中国在对外交往中始终强调亲仁善邻、和而不同。2000 多年前，中国与周边国家有使节往来、商品交易、文化交流，汉朝张骞出使西域开辟了陆上“丝绸之路”。1000多年前，中国对外 交往海陆并重，盛况空前，茶叶、丝绸、瓷器等商品远销亚欧诸多国家；600多年前，中国明代航海家郑和率领舰队“七下西洋”，足迹遍及亚非30多个国家和地区，带去的是先进的农耕和手工艺技术，还有精美的产品和真诚的友谊。这样的文化传统决定了今天的中国必然选择和平发展延续历史，并融入当今世界和平与发展的潮流。

从 19 世纪 80 年代之后的鸦片战争、甲午战争，到庚子之乱乃至20世纪30年代的日本侵华战争，中国惨遭东西方列强的屠戮和极其野蛮的经济掠夺；再加上封建腐败和连年内乱，中国主权沦丧、生灵涂炭、国力衰弱、民不聊生。深重的灾难、惨痛的事实使中华民族深知和平之珍贵、发展之重要。这样的历史实践形成了中国人民渴望和平、企求安定的心理，坚定了中国人民走和平发展道路的信念。

1949 年新中国成立后，我们在发展道路上艰辛探索，既经历过成功的喜悦，也经受过失败的挫折。从 1978 年开始，中国开启了新的征程，从计划转向市场，从封闭转向开放，从自成一体转向融入经济全球化，走独立自主地建设中国特色社会主义的道路，取得了举世瞩目的辉煌成就。实践充分证明，坚持走和平发展的道路是正确的，既符合中国国情，又顺应时代潮流。中国将沿着这条和平发展的道路，坚定不移地走下去。

governments are creating a global network of plant banks to store seeds and sprouts, precious genetic resources that may be needed for man to adapt the world? s food supply to climate change.

This week, the flagship of that effort, the Global Seed Vault near here, received its first seeds, millions of them. Bored into the middle of a frozen Arctic mountain topped with snow, the vault? s goal is to store and protect samples of every type of seed from every seed collection in the world.

As of Thursday, thousands of neatly stacked and labeled gray boxes of seeds — peas from Nigeria, corn from Mexico — reside in this glazed cavelike structure, forming a sort of backup hard drive, in case natural disasters or human errors erase the seeds from the outside world.

Descending almost 500 feet under the permafrost, the entrance tunnel to the seed vault is designed to withstand bomb blasts and earthquakes. An automated digital monitoring system controls temperature and provides security akin to a missile silo or Fort Knox. No one person has all the codes for entrance.

The Global Vault is part of a broader effort to gather and systematize information about plants and their genes, which climate change experts say may indeed prove more valuable than gold. In Leuven, Belgium, scientists are scouring the world for banana samples and preserving their shoots in liquid nitrogen before they become extinct. A similar effort is under way in France on coffee plants. A number of plants, most from the tropics, do not produce seeds that can be stored.

For years, a hodgepodge network of seed banks has been amassing seed and shoot collections in a haphazard manner. Labs in Mexico banked corn species. Those in Nigeria banked cassava. Now these scattershot efforts are being urgently consolidated and systematized, in part because of better technology to preserve plant genes and in part because of the rising alarm about climate change and its impact on world food production.

“We started thinking about this post-9/11 and on the heels of Hurricane Katrina,” said Cary Fowler, president of the Global Crop Diversity Trust, a nonprofit group that runs the vault. “Everyone was saying, why didn? t anyone prepare for a hurricane before? We knew it was going to happen.“Well, we are losing biodiversity every day — it? s a kind of drip, drip, drip. It? s also inevitable. We need to do something about it.”

This week the urgency of the problem was underscored as wheat prices rose to record highs and wheat stores dropped to the lowest level in 35 years. A series of droughts and new diseases cut wheat production in many parts of the world. “The erosion of plants? genetic resources is really going fast,” said Dr. Rony Swennen, head of the division of crop biotechnology at the Catholic University of Leuven in Belgium, who has preserved half of the world? s 1,200 banana types. “We? re at a critical moment and if we don? t act fast, we? re going to lose a lot of plants that we may need.”

The United Nations International Treaty on Plant Genetic Resources, ratified in 2004, created a formal global network for banking and sharing seeds, as well as for studying their genetic traits. Last year, its database received thousands of new seeds.

A system of plant banks could be crucial in responding to climate crises since it could identify genetic material and plant strains better able to cope with a changed environment.

Here at the Global Vault, hundreds of gray boxes containing seeds from places ranging from Syria to Mexico were moved this week into a freezing vault to be placed in suspended animation. They harbor a vast range of qualities, like the ability to withstand drier, warmer climate.

um wheat, used to make high quality Italian pasta. Today it overflows with rapeseed, a tall, gnarled weedlike plant bursting with coarse yellow flowers that has become a new manna for European farmers: rapeseed can be turned into biofuel.

Lured by generous new subsidies to develop alternative energy sources - and a measure of concern about the future of the planet - European farmers are plunging into growing crops that can be turned into fuels meant to produce fewer emissions than gas or oil when burned. They are chasing after their counterparts in the Americas who have been cropping for biofuel for more than five years.

"This is a much-needed boost to our economy, our farms," said Marcello Pini, a farmer, standing in front of the sea of waving yellow flowers he planted for the first time this year. "Of course we hope it helps the environment, too."

In March, the European Commission, disappointed by the slow growth of thebiofuels industry in Europe, approved a directive that included a "binding target" requiring member states to use 10 percent biofuel for transport by 2020 - the most ambitious and specific goal in the world.

Most EU states are currently far from achieving the target, and are introducing new incentives and subsidies to boost production.

As a result, bioenergy crops have now replaced food as the most profitable crop in a number European countries. In this part of Italy, for example, the government guarantees the purchase of biofuel crops at €22 per 100 kilograms, or $13.42 per 100 pounds - nearly twice the €11-to-€12 rate per 100 kilograms of wheat on the open market last year. Better still, European farmers are allowed to plant biofuel crops on "set-aside" fields, land that EU agriculture policy would otherwise require them to leave fallow to prevent an oversupply of food.

But an expert panel convened by the UN Food and Agriculture Organization this month pointed out that the biofuels boom produces both benefits as well as tradeoff and risks - including higher and wildly fluctuating global food prices. In some markets grain prices have nearly doubled because farmers are planting for biofuels,

"At a time when agricultural prices are low, in comes biofuel and improves the lot of farmers and injects life into rural areas," said Gustavo Best, an expert at the United Nations Food and Agriculture Organization in Rome. "But as the scale grows and the demand for biofuel crops seems to be infinite, we&39;re seeing some negative effects and we need to hold up a yellow light."

Josette Sheeran, the new head of the UN World Food program, which fed nearly 90 million people in 2006, said that biofuels created new dilemmas for her agency. "An increase in grain prices impacts us because we are a major procurer of grain for food. So biofuels are both a challenge and an opportunity." In Europe, the rapid conversion of fields that once grew wheat or barley to biofuel oils like rapeseed is already leading to shortages of ingredients for making pasta and brewing beer, suppliers say. That could translate into higher prices in supermarkets.

"New and increasing demand for bioenergy production has put high pressure on the whole world grain market," said Claudia Conti, a spokeswoman for Barilla, one of the largest Italian pasta makers. "Not only German beer producers, but Mexican tortilla makers have see the cost of their main raw material growing quickly to quickly to historical highs."

For some experts, more worrisome is the potential impact to low-income consumers from the displacement of food crops by bioenergy plantings. In the developing world, the shift from growing food to growing more lucrative biofuel crops destined for richer countries could create serious hunger and damage the environment in places where wild land is converted to biofuel cultivation, the FAO expert panel concluded.

But officials at the European Commission say they are pursuing a measured course that will prevent the worst price and supply problems that have plagued American markets.

"We see in the United States farmers going crazy growing corn for biofuels, but also producing shortages of food and feed," said Michael Mann, a commission spokesman. "So we see biofuel as a good opportunity - but it shouldn&39;t be the be-all and end-all for agriculture."

In a recent speech, Mariann Fischer Boel, the EU agriculture and rural development commissioner, said that the 10 percent EU target was "not a shot in the dark," but rather carefully chosen to encourage a level of biofuel industry growth that would not produce undue hardship for the Continent&39;s poor. Over the next 14 years, she calculated, it would push up would raw material prices for cereal by 3 percent to 6 percent by 2020, while prices for oilseed may rise between 5 percent and 18 percent. But food prices on the shelves would barely change, she said.

好的大象。

他们说，中国的崛起不会对其他们存在任何威胁。中国有5000年的文明史，有过辉煌的过去，也有过屈辱的往事。中国的崛起是多少代中国人的梦想。中国和平崛起的要义在什么地方？

第一，中国和平崛起就是要充分利用世界和平的大好时机，努力发展和壮大自己。同时又以自己的发展，维护世界和平。

第二，中国的崛起应把基点主要放在自己的力量上，独立自主、自力更生，艰苦奋斗，依靠广阔的国内市场、充足的劳动力资源和雄厚的资金储备，以及改革带来的机制创新。

第三，中国的崛起离不开世界。中国必须坚持开放的政策，在平等互利的原则上，同世界一切友好国家发展经贸往来。

第四，中国的崛起需要很长的时间，恐怕要多少代人的努力奋斗。

第五，中国的崛起不会妨碍任何人，也不会威胁任何人，也不会牺牲任何人。中国现在不称霸，将来即使强大了也永远不会称霸。
