Onions make you cry, add flavor to food and win popularity for their medicinal benefits. Now the vegetable has another use—_____ green energy.

Anew system debuts（首次亮相）on Friday that _____ onion juice into electricity at Gills Onions, the largest fresh onion processor in the United States.

The Oxnard, California-based company _____ its new onion-fueled power to reduce its electric bill by $700,000 a year and _____ its annual greenhouse gas emissions by up to 30,000 tons.

The _____ ending to this green energy tale, however, started with another question: how to _____ onion waste.

“_____ we peel an onion, 35 to 40 percent of the onion comes off before we have a(n)_____ onion. That's the top, tail and skin around the onion, and _____ we can get to the meat,” said Steven Gill, co-owner of the 25-year-old company.

They used to pull the waste to the fields for compost（混合肥料）, but that turned out to be a tough ______. Ten years ago, Gill started looking at technology for a(n) _____, including microturbines（微型燃气轮机）.

“We ______ cutting the skins into pieces and extracting all the ______, which is very high in sugars, and bacteria love that stuff,” Gill said.

In the new system, bacteria ______ methane（甲烷）gas from the juice. The gas then goes to two 300 kilowatt fuel cells, creating ______ power for 460 homes. If everything goes smoothly, ______ are that the company will get 35 to 40 percent of its electricity from the on-site generator.

The company ______ $ 9. 5 million in the project and will receive $2. 7 million from Southern California Gas Co. _____ cutting its electric bill, the company will save $400,000 in costs and expects paybacks in the new future.

The onion grower now has a new ______: to be a zero-waste facility in the coming decade.

“We want to ______ it all the way through and make the full circle,” Gill said.

   Trying to fight against the nation's food waste problem，Denmark opened the world's first supermarket that sells expired（到期的）or damaged products.

Ever since it was opened in Copenhagen，people have been standing in line outside WeFood for a chance to buy discounted items that would otherwise have ended up being rubbish because of damaged packing or very short use-by dates. Food，cosmetics，and other household items at WeFood are priced at least 30% to 50% lower than those at regular stores.

It's foolish to throw away or let food go to waste," said Hansen, former Minister for Food and Environment." It's bad for the environment and obviously it is money spent on nothing. A supermarket like WeFood makes so much sense and is an important step in the battle to fight against food waste."

While Denmark alone is said to waste about 700,000 tons of food this year, the United Nations has stated that globally, food waste adds up to 1.3 billion tons. It is really shocking, considering that about795million people in the world are still short of food. Denmark, however, has taken measures. As a result, it wastes 25% less food than it did five years ago.

The We Food project is cooperation between the Food Bank and Dan Church Aid. Together they have collected over s 150，000 over the past years. They faced many problems while convincing the government to permit the sale of expired or damaged products. They were finally allowed to carry out the project，and the store is now specially run by volunteers. The money it earns is used to provide funds（基金）for Dan Church Aid's other projects in developing nations.

If We Food can successfully maintain its goods deliveries and remain popular in the long term，Dan Church Aid plans to open many other branches across Denmark.

   A new tool of communication called the "drift diary" is doing the rounds among young college graduates.

The "drift diary", like those ancient paper messages put into a bottle left to drift on the high seas to reach hundreds of miles away, connects lonely hearts. It was first started by a Beijing woman, who goes by the screen name Little S, in 2007.It has become the preferred tool of communication among youngsters afraid to reveal their innermost self to peers, but wanting to share their lives with others. The way it works is that the initiator（发起人）of the diary mentions it on popular Internet forums such as Tianya and Douban. Those wanting to react or otherwise add to the diary then send their real names and addresses to the initiator via e-mails or text messages.

The numbers in one group are usually restricted to between 30 and 50. The diary then is passed on to another by the express delivery or personal handover. The diary writers are mostly anonymous（匿名的）but if they wish to reveal their identity they can do so by posting their contact information at the end of their postings.

The diary writers not just add words but also decorate the plain notebooks with cartoons, drawings or even dress it up with a ribbon or a new cover. Interesting experiences, travel journals, the simple joys of everyday living or sweet recollections of childhood, all find a place in these diaries. Most often, though, the writers set down their frustrations and predicaments.

It usually takes one year for a diary to return to the initiator. The last recorder is the luckiest one, with access to all previous entries, while others can request photocopies of them from the diary's initiator.
