   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.

   Every pet owner loves his pet. There is no argument here.

But when we asked our readers whether they would clone their beloved animals，the responses（反应）were split almost down the middle. Of the 228 readers who answered it，108 would clone their beloved animals，111 would not and nine weighed each side without offering an opinion.

Clearly，from readers’responses，this is an issue that reaches deeply into both the joy and eventual sadness of owning a pet. It also shows people’s widely different expectations over the developing scientific procedure.

Most of the respondents who favored the idea strongly believed it would produce at least a close copy of the original；many felt the process would actually return an exact copy. Those on the other side，however，held little hope that cloning could truly recreate a pet；many simply didn’t wish to go against the natural law of life and death.

Both sides expressed equal love for their animals. More than a few respondents owned“the dog/cat in the world”.They thought of their pets as their“best friend”，“a member of the family”，“the light of their life”.They told moving stories of pets’ heroism，intelligence and selfless devotion.

Few wonder the loss is so disturbing（令人不安的）and the cloning so attractive.“People become very close to their animals，and the loss can be just as hard to bear as when a friend or family member dies，”says Gary A. Kowalski，author of Goodbye Friend：Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me，cloning feels like an attempt to turn death away... It’s understandable. Death is always painful. It’s difficult to deal with it. It’s hard to accept.”

But would cloning reduce the blow? This question seemed to be at the heart of this problem.
