  Onions make you cry,add flavor to food and are praised for their medical benefits. Now the vegetable has another use―powering up green energy.

  A new system was first used on Friday that converted onion juice into electricity at Gills Onions,the largest fresh onion processor in the United States.

The Oxnard,Californiabased company expects its new onionfueled power to reduce its electric bill by $700,000 a year and cut its annual greenhouse gas emissions by up to 30 ,000 tons.

  The happy ending to this green energy tale,however,started with another question:how to get rid of onion waste.

  "When we peel an onion,35 to 40 percent of the onion comes off before we have a usable onion. That's the top,tail and skin around the onion before you get to the meat," said Steven Gill,coowner of the 25-year-old company.

  They used to put the waste into the fields for composting,but that became a problem. Ten years ago,Gill started looking at technology for a solution.

  "We ended up cutting up the skins as they come out of the plant and extracting all the juice,which is very high in sugars,and bacteria love that stuff," Gill said.

In the new system,bacteria produce methane gas from the juice. The gas then goes to two 300-kilowatt fuel cells,creating enough power for 460 homes. The company expects to get 35-40 percent of its electricity from the onsite generator.

  The company invested $9. 5 million in the project and will receive $ 2. 7 million from Southern California Gas Co.,as part of a state program to encourage selfcontained generation by businesses. In addition to cutting its electric bill,the company will save $400,000 in trans?port expense and expects payback in six years.

(   ) 6. What's the new use of onions mentioned in the text?

   A. To make people energetic. B. For medical use.

   C. To produce green power. D. For composting the fields.

(   ) 7. Which of the statements is true according to the passage?

   A. The Oxnard expects to reduce its electric bill to $ 700,000 a year.

   B. This project comes from the solution to deal with onion waste.

   C. How to get rid of onion waste remains a big problem.

   D. The juice extracted from onion is low in sugar.

(   ) 8. We can learn from the passage that         .

   A. the researchers are trying to get rid of bacteria in onion

   B. Steven Gill is 25 years old

   C. it is the bacteria that helps to produce energy from the juice

   D. the company will make a profit of $400,000 in six years

(   ) 9. What's the main idea of the text?

 The United States government wants to know what the public thinks about its findings on the safety of cloned animals.

  The Food and Drug Administration says meat and milk from clones of adult cattle,pigs and goats are safe to eat. An F. D. A. official called them "as safe to eat as the food we eat every day. " And when those clones reproduce sexually,the agency says,their offspring (后代) are safe to eat as well. But research on cloned sheep is limited. So the F. D. A. proposes that sheep clones not be used for human food.

  The United States this year could become the first country to approve the sale of foods from cloned animals. First,however,the public will have ninety days to comment on three proposed documents. On December 28th the F. D. A. released a long report,called a draft risk assess?ment,along with two policy documents.

  The agency says it must receive comments by April second. The F. D. A. seemed ready to act several years ago,but an advisory committee called for more research.

  For now,the government will continue to ask producers to honor a request that they not sell foods from cloned animals.

  Clones are still rare. They cost a lot and are difficult to produce.

  The F. D. A. says most food from cloning is expected to come not from clones themselves,but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.

  Public opinion studies show most Americans do not like the idea of food from cloned ani?mals. But this research also shows the public knows little about cloning.

  Cloning differs from genetic engineering. A cell taken from a socalled donor animals is grown into an embryo (胚胎) in the laboratory. Next,the embryo is placed into the uterus (子宫) of a female animal. If the process is successful,the pregnancy reaches full term and a genetic copy of the donor animal is born.

(   ) 1. From the passage we know that         .

   A. foods from cloned animals are popular in America

   B. cloned adult animals are safe to eat except sheep

   C. cloned animals will be easy to produce

   D. most foods from cloning are expected to take place of other foods

(   ) 2. The main purpose of the text is to         .

   A. tell an interesting story   B. give some advice on foods

   C. give a report   D. compare different opinions

(   ) 3. Who believes that foods from cloning are safe to eat?

   A. Most Americans. B. An advisory committee.

   C. Critics. D. The F. D. A.

(   ) 4. It can be inferred from the last paragraph that         .

   A. cloning has much in common with genetic

   B. not every cell taken from a donor animal can grow into a genetic copy

   C. the donor animal should be a female one

   D. cloned animals grow faster than normal ones

 We know the famous ones―the Thomas Edisons and the Alexander Graham Bells,but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper (雨刮器) ? Shouldn't we know who they are?

  Joan McLean thinks so. In fact,McLean,a professor of physics at Mountain University in Range,feels so strongly about this matter that she's developed a course on the topic. In addition to learning "who" invented "what",McLean also likes her students to learn the answers to the "why" and "how" questions. According to McLean, "When students learn the answers to these questions,they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try,"

  Her students agree. One young man with a patent for an unbreakable umbrella is walking proof of McLean's statement. "If I had not heard the story of the windshield wiper's inven?tion ,"said Tommy Lee,a senior physics major, "I would never have dreamed of turning my bad experience during a rainstorm into something so constructive. " Lee is currently negotiating to sell his patent to an umbrella producer.

  So,just what is the story behind the windshield wiper? Well,Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy,but Anderson still wanted to see the sights,so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield,she found herself wondering why there couldn't be a builtin device for cleaning the window. Still wondering about this when she returned home to Birmingham,Alabama,Anderson started drafting out solutions. One of her ideas,a lever (操作杆) on the inside of a vehicle that would control an arm on the outside,became the first windshield wiper.

  Today we benefit from countless inventions and innovations. It's hard to imagine driving without Garrett A. Morgan's traffic light. It's equally impossible to picture a world without Katherine J. Blodgett's innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses?

(   ) 1. By mentioning "traffic light" and " windshield wiper" , the author indicates that countless inventions are         .

   A. beneficial,because their inventors are famous

   B. beneficial,though their inventors are less famous

   C. not useful,because their inventors are less famous

   D. not useful,though their inventors are famous

(   ) 2. Professor Joan McLean's course aims to .

   A. add colour and variety to students' campus life

   B. inform students of the windshield wiper's invention

   C. carry out the requirements by Mountain University

   D. prepare students to try their own inventions

(   ) 3. Tommy Lee's invention of the unbreakable umbrella was         .

   A. not eventually accepted by the umbrella producer

   B. inspired by the story behind the windshield wiper

   C. due to his dream of being caught in a rainstorm

   D. not related to Professor Joan McLean's lectures

(   ) 4. Which of the following can best serve as the title of this passage?

   A. How to Help Students to Sell Their Inventions to Producers?

   B. How to Design a Builtin Device for Cleaning the Window?

   C. Shouldn't We Know Who Invented the Windshield Wiper?

   D. Shouldn't We Develop Invention Courses in Universities?

 David Wroblewski's The Story of Edgar Sawtelle explores the silent world of the novel's hero,Edgar Sawtelle,living in Wisconsin during the middle of the 20th century. Born unable to speak,the boy seems to prefer the language of dogs more than the words of people. From his earliest memories,his favorite job on the farm was to name the new born dogs. As he grows older,his connection with the dogs becomes deeper. He helps to train them through sign lan?guage.

  The novel begins with Edgar's grandfather,telling readers about how the dog farm began. When Edgar's father,Gar,dies strangely,Edgar blames his uncle,Claude,his father's younger brother,who has meant nothing but trouble for the family. When Claude falls in love with Edgar's mother,Trudy,Edgar is shocked and very angry.

  The story is filled with loving family memories until Claude arrives,returning to the farm he abandoned long ago. Edgar finds Claude to be twofaced. The man presents his best side to Edgar's mother. She falls in love with him,allowing him to fill in the vacant spaces left behind from her husband's death. Edgar sees the other side of Claude,a side that Edgar finds danger?ous.

  When tensions become too strong between Edgar and Claude,Edgar takes his favorite dogs and runs away from home. For the story itself,this tension raises the level of curiosity for the reader. It is at this point that the novel takes on the form of a mystery or a sort of detective story. Edgar fears that the police are looking for him because of an accidental death that he played a part in. Readers may worry that Edgar might be caught because Claude tells local offi?cials that Edgar committed murder. In the end,it is Edgar against Claude―a fight to the finish. Unfortunately,there are no winners.

  The Story of Edgar Sawtelle was Wroblewski's first novel. It took him ten years to com?plete it. Literary critics praise the author's writing,especially in the first half of the story. Some critics,however,hold the opposite opinion. And,some have found the second half to be too artificially operated.

  Once a month the nun marched us to the church,where we would stand in line to say our confession (忏'海) .Bless me,Father,for I have sinned (豸巳罪) ,my last confession was a month ago. These are my sins: "I stole a magazine and I called my younger brother a fucking head."

  I thought it a great bargain that a few "Hail Marys" forgave me of my sins. Sometimes the kid ahead of me in line stayed a long time inside the confessional,and I wondered what horrible crimes he had committed. Now we can know what sins others commit,there are Web sites suddenly appear all over the Internet that allow penitents (悔罪者) to publicly confess their sins.

  A woman kept her secret for nearly two decades. Finally ready to confess,she turned not to a minister,but to her computer: " I am sorry,God,for not keeping that baby”,her confession reads. "I had kept that secret for over 18 years. I feel so ashamed. Please forgive me!"

  The confession appears at ivescrewedup. com,a website launched by the Flamingo Road Church in Cooper City. It's one of a growing number of such sites across the country that offer a place to spill out ugly secrets or just make sins public.

  Online confessions are a wonderful thing for a poor soul burdened with guilt,it allows him to clear his conscience without the mediation (调停,斡旋) of a priest. When a sinner confesses his evil ways to his favorite god,he doesn't receive an email notifying him that his prayer has reached its destination.

  But when you post your sins online,they are visible to the whole world,and at the very least you know that others have read your confession.

If you feel the need to confess your shortcomings online,feel free to visit dailyconfession.com or mysecret.tv.
