If two scientists at Los Alamos National Laboratory are correct, people will still be driving gasoline-powered cars 50 years from now, giving out heat-trapping carbon dioxide into the atmosphere — and yet that carbon dioxide will not contribute to global warming.

In a proposal by two scientists, vehicle emissions (排放) would no longer contribute to global warming. The scientists, F. Jeffrey Martin and William L. Kubic Jr., are proposing a concept, which they have named Green Freedom, for removing carbon dioxide from the air and turning it back into gasoline.

The idea is simple. Air would be blown over a liquid solution (溶液) of potassium carbonate, which would absorb the carbon dioxide. The carbon dioxide would then be put to chemical reactions that would turn it into fuel: gasoline or jet fuel.

This process could change carbon dioxide from an unwanted, climate-changing pollutant into a vast resource for renewable fuels. The cycle — equal amounts of carbon dioxide produced and removed — would mean that cars, trucks and airplanes using the synthetic (合成的) fuels would no longer be contributing to global warming.

Although they have not yet built a synthetic fuel factory, or even a small model, the scientists say it is all based on existing technology. “Everything in the concept has been built, is operating or has a close cousin that is operating,” Dr. Martin said.

The Los Alamos proposal does not go against any laws of physics, and other scientists who have independently suggested similar ideas. Dr. Martin said he and Dr. Kubic had worked out their concept in more detail than previous proposals.

There is, however, a major fact that explains why no one has built a carbon-dioxide-to-gasoline factory: it requires a great deal of energy.

According to their analysis, their concept, which would cost about $5 billion to build, could produce gasoline at an operating cost of $1.40 a gallon and would turn economically practical when the price at the pump hits $4.60 a gallon.

Other scientists said the Los Alamos proposal perhaps looked promising but could not evaluate it fully because the details had not been published.

“It’s definitely worth pursuing,” said Martin I. Hoffert, a professor of physics at New York University. “It’s not that new an idea. It has a couple of pieces to it that are interesting.”

In 2007，five young people in the American state of Massachusetts developed an idea．The team knew that the world is filled with mobile phones．About 80% of all people are said to live within reach of a wireless telephone signal．

The idea was to use mobile phones and the Interact to connect job seekers with employers．The young people wrote a business plan and formed a company called Assured Labor．

Assured Labor won a development competition at the Massachusetts Institute of Technology（MIT）．Three of the founders were graduate students there．

Assured Labor is an electronic marketplace．It has two parts．One is for the United States．That operation was launched in January in Boston．It links people with employers offering temporary jobs．The other arm of the business is for developing markets．That operation is meant to help people get more permanent jobs．A representative is currently building partnerships with universities and international companies in Central America．

Assured Labor's president，David Reich，says the companies are interested in having more modern hiring practices．Through Assured Labor，companies will list open positions on the Internet．People who think they could do the job could reply by text message or on their cell phones．

This is how the system works in Boston: The jobs available include house cleaning，dog walking and home repair．People who want their house cleaned，for example，can look online at a list of twenty housekeepers．The list tells what services they offer and how much they want to be paid．People need two letters praising their work to get on the list of service providers．The employer chooses workers they would like to hire．The company then sends the workers a text or e-mail message so they can respond quickly to an offer．After a job is completed，the employer and employee evaluate each other．The evaluation is kept for future use．

Assured Labor is not charging anyone right now，but the plan is to have employers pay for the service．

1．What is the idea of Assured Labor based on?

A．Technology of mobile phones and the Internet．

B．Technology support by Massachusetts Institute of Technology．

a．Assured Labor informs the worker of the job available．

b．The employer chooses a worker from a list online．

c．The employer and the worker evaluate each other．

d．The worker responds to the offer and does the job．

A．a-b-c-d             B．b-a-d-e                   C．a-b-d-c             D．b-a-c-d

My grandparents were married for over half a century, and played their own special game from the time they met each other. The goal of their game was to write the word “shmily” in a surprise place for the other to find.

“Shmily” was written in the steam left on the mirror after a hot shower, where it would reappear bath after bath. At one point, my grandmother even opened an entire roll of toilet paper to leave “shmily” on the very last sheet. Little notes with “shmily” scribbled (潦草地写) hurriedly were found on dashboards (仪表板) and car seats, or taped to steering wheels.

It took me a long time before I was able to fully appreciate my grandparents’ game. Skepticism (怀疑态度) had kept me from believing in true love — one that is pure and lasting. However, I never doubted my grandparents’ relationship. They had love down pat. It was more than their flirtatious (爱调戏的) little games; it was a way of life. Their relationship was based on devotion and passionate love.

Grandma and Grandpa held hands every chance they could. They stole kisses as they bumped into each other in their tiny kitchen. They finished each other’s sentences and shared the daily crossword puzzle and word jumble. My grandma whispered to me about how cute my grandpa was, how handsome and old he had grown to be. She claimed that she really knew “how to pick ‘em.”

But there came a dark cloud into my grandparents’ life: when my grandmother got breast cancer. Gradually it took over the whole of her body. One day, what we all dreaded finally happened. Grandma was gone.

“Shmily.” It was scrawled in yellow on the pink ribbons of my grandmother’s funeral bouquet (花束). The family came forward and gathered around Grandma one last time. Grandpa stepped up to my grandmother’s casket (棺) and, taking a shaky breath, he began to sing to her. Through his tears and sadness, the song came, a deep and throaty lullaby (催眠曲,). Shaking with my own sorrow, I would never forget that moment.

What is the hottest topic at your school recently? In Hangzhou Yongjin Middle School, it’ s money.

The school held an activity called “making money” last weekend. About 200 Junior 1 and Junior 2 students were divided into 30 teams. They went out ___________________________. What did they choose to sell? Some sold newspapers；some chose bottled water；some sold environmentally friendly shopping bags and bamboo baskets.

Hu Qing’ s team decided to sell some useful books in front of the Children Activity Center. They thought parents would like to buy the books for their children. But unfortunately, they met urban management officers. The officers asked them to leave. “We played hide-and-seek with the offices for the whole morning,” said Hu. “Finally we had to give up.”

Wang Bing and her team sold ice cream in a square. They didn’ t meet any officers. But few people were interested in what they were selling. The team then put up a board saying “For Country Kids”. It worked. More people came to their stall（小摊）. A foreigner even gave them 100 Yuan. “He didn’ t want any change. He said he wanted to help the children,” said Wang. “We were touched.” Later that day they gave the 100 Yuan and more to the “Project Hope” office.

Meng Zhaoxiang and his team were luckier. They sold all their cakes in four hours, spending 39.5 Yuan and getting back 80 Yuan. They made 40.5 Yuan. “It was not easy to make the money,” said Meng. “Some people just looked. Others just tasted but didn’ t buy. Now I know how hard it is for our parents to make money we need to lead happy lives. ”

An idea that started in Seattle's public library has spread throughout America and beyond. The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time.

In addition to encouraging reading as a pursuit(追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched(发起) the "If All of Seattle Read the Same Book " project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.

In Chicago, the mayor(市长) appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighborhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.

   The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity can be achieved. Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself.

Ultimately, as Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process, or have enjoyed speaking to someone with whom they would not otherwise have shared a word.

1.What is the purpose of the project launched by Nancy?

A. To invite authors to guide readers.

B. To encourage people to read and share.

C. To involve people in community service.

D. To promote the friendship between cities.

2. Why was it difficult for New Yorkers to carry out the project?

A. They had little interest in reading.

B. They were too busy to read a book.

C. They came from many different backgrounds.

D. They lacked support from the local government.

3.According to the passage, where would the project be more easily carried out?

A. In large communities with little sense of unity.

B. In large cities where libraries are far from home.

C. In medium-sized cities with a diverse population.

D. In large towns where agreement can be quickly reached.

4. The underlined words “shared a word” in Paragraph 5 probably mean      .

A. exchanged ideas with each other

B. discussed the meaning of a word

C. gained life experience

D. used the same language

5.According to Nancy, the degree of students of the project is judged by           .

A. the careful selection of a proper book

B. the growing popularity of the writers

C. the number of people who benefit from reading

D. the number of books that each person reads
