There was once a guy who suffered from cancer, a cancer that can't be cured. One day he was sick of staying home and wanted to go out. He passed a CD store and looked through the front door for a second. He saw a beautiful girl about his age and he knew it was love at first sight. He opened the door and walked in, not looking at anything else but her. He walked closer and closer until he was finally at the front desk where she sat.

    She looked up and asked, “Can I help you?” She smiled and he thought it was the most beautiful smile he had ever seen before. He said, “UH…Yeah…Umm… I would like to buy a CD.” He picked one out and gave her money for it. “Would you like me to pack it for you?” she asked, smiling her cute smile again. He nodded and she went to the back. She came back with the packed CD and gave it to him.

     From then on, he went to that store every day and bought a CD. He took the CD home and put it in his closet. He was still too shy to ask her out. His mother found out about this and encouraged him. So the next day, he took all his courage and left his phone number on the desk before he ran out.

    Several weeks later the phone rang, and the mother picked it up. It was the girl!!! The mother started to cry and said, “You don't know? He passed away yesterday…” Later that day, the mother went into the boy's room and opened the closet. Inside were piles and piles of unopened CDs. She picked one up and opened it. Out fell a piece of paper, saying: “Do you want to go out with me? Love, Jocelyn.” The mother was deeply moved and opened another CD… Again, there was a piece of paper with the same words.

    Ammie Reddick was only 18 months old when she had the accident that had scarred（留下创伤） her for life. The curious child reached up to grab the wire of a hot kettle in the family kitchen and poured boiling water over her tiny infant frame.

    Her mother Ruby turned round and, seeing Ammie horribly burnt, called an ambulance which rushed her daughter to a nearby hospital. Twenty percent of Ammie's body had been burned and all of her burns were third-degree. There, using tissue taken from unburned areas of Ammie's body, doctors performed complex skin transplants to close her wounds and control her injuries. Over the next 16 years, Ammie underwent 12 more operations to repair her body.

    When she started school at Maxwelton Primary at age 4, other pupils made cruel comments or simply wouldn't play with her. “I was the only burned child in the street, the class and the school,” she recalled, “some children refused to become friends because of that.”

    Today, aged 17, Ammie can only ever remember being a burned person with scars; pain is a everlasting part of her body. Yet she is a confident, outgoing teenager who offers inspiration and hope to other young burns victims.

    She is a member of the Scottish Burned Children's Club, a charity set up last year. This month, Ammie will be joining the younger children at the Graffham Water Center in Cambridgeshire for the charity's first summer camp. “I'll show them how to get rid of unkind stares from others,” she says. Ammie loves wearing fashionable sleeveless tops, and she plans to show the youngsters at the summer camp that they can too. “I do not go to great lengths to hide my burns scars,” she says, “I gave up wondering how other people would react years ago.”

    When you cross deep water driving too fast, you risk splashing water up into the air box and having it get sucked into the internal engine, which is more common than you think. There are a few steps you should take to clear the water out before you try to start it:

    ⒈First, drain the fuel tank, fuel lines and the oil. While it's draining, put a fan on the wiring and dry it out. Remove and clean the carburetor (化油器).

    ⒉Take the plugs out of the engine and turn it over to force any water out. Water will come out with the oil. Add oil to the engine and turn it over again, without the plug in. Let it sit for a while, then observe the oil to tell if there's any water in it (it will look like a white milky substance if there is water mixed with the oil). If it's there, drain it again and start over until there is little or no white showing in the oil.

    ⒊Now re-install the spark plug, add gas, then try to start the engine. You should have a can of ether (乙醚) handy just in case it's stubborn, but don't use too much. If it starts, let it run for a few minutes without making it work faster.

    ⒋After it runs for several minutes, shut it off, drain the oil and change the filter(过滤网). Run it again for a few minutes then shut it off and checks again for milky colored oil. If you have none, you should be good to go.

    ⒌If you cannot start the engine, you may have already ruined it and you will probably need to seek a professional to repair it, or, more likely, you'll have to replace it.

    Suppose you become a leader in an organization. It's very likely that you'll want to have volunteers to help with the organization's activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interest in the work.

    Let's begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.

    People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift people's wish of participation from an internal factor (e.g. "I volunteer because it's important to me") to an external factor (e.g. "I volunteer because I'm required to do so"). When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activities a must.

    Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to "training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience".

    Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view "volunteer" as an important social role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also be most likely to continue volunteer work. Participants indicated the degree to which the social role mattered by responding to statements such as "Volunteering in Hospital is an important part of who I am." Consistent with the researchers' expectations, they found a positive correlation (正相关) between the strength of role identity and the length of time people continued to volunteer. These results, once again, lead to concrete advice: "Once an individual begins volunteering, continued efforts might focus on developing a volunteer role identity…Items like T-shirts that allow volunteers to be recognized publicly for their contributions can help strengthen role identity".

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the California Institute of Technology have-in just two years-nearly doubled the number of materials known to have potential for use in solar fuels.

They did so by developing a process that promises to speed the discovery of commercially viable (商业可行性) generation of solar fuels that could replace coal, oil, and other fossil fuels.

Solar fuels, a dream of clean-energy research, are created using only sunlight, water, and carbon dioxide. Researchers are exploring a range of possible target fuels, but one possibility is to produce hydrogen by splitting water.

Each water molecule (分子) consists of one oxygen atom and two hydrogen atoms. The hydrogen atoms are extracted, and then can be reunited to create highly flammable hydrogen gas or combined with CO 2 to create hydrocarbon fuels, creating a plentiful and renewable energy source. The problem, however, is that water molecules do not simply break down when sunlight shines on them-if they did, the oceans would not cover most of the planet. They need a little help from a solar-powered catalyst (催化剂).

To create practical solar fuels, scientists have been trying to develop low-cost and efficient materials that perform the necessary chemistry using only visible light as an energy source.

A new method was developed through a partnership between the Joint Center for Artificial Photosynthesis (JCAP) and Berkeley Lab's Materials Project, using resources at the Molecular Foundry and the National Energy Research Scientific Computing Center (NERSCC). JCAP focused on developing a cost-effective method of turning sunlight, water, and carbon dioxide into fuel. It is led by Caltech with Berkeley Lab as a major partner. The Materials Project is a program based at Berkeley Lab that aims to remove the guesswork from materials design in a variety of applications.

"What is particularly significant about this study, which combines experiment and theory, is that in addition to identifying several new compounds for solar fuel applications, we can also learn something new about the basic electronic structure of the materials themselves." says Neaton, the director of the Molecular Foundry.
