    Want to find a job? Now read the following advertisement.

    As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.

    Three Chilean students got the idea for a plant-powered device(装置) to charge their cellphones, while sitting in their school's outdoor courtyard during a break from exams, with dead mobile phones. Then, one of them had an "aha" moment.

    “It occurred to Camila to say about plants,” said inventor Evelyn Aravena. “'Why don't you have a socket, if there are so many plants? 'After that, we thought, 'why don't they have a charging outlet? Because there are so many plants and living things that have the potential to produce energy, why not?'”

    Their invention—a small biological circuit called E-Kaia—uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.

    "It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them." said Mauricio Cifuentes.

    The device solved two problems for the engineering students — they needed an idea for a class project, and an outlet to plug in their phones.

    "Looking for a place to charge the notebook, which had no power, and the mobile phones, we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.

    But plants are everywhere, and the bio－circuit makes the best of their excess(过多的) power.

    The E-Kaia doesn't carry much charge but it's powerful enough to completely recharge a mobile phone in less than two hours.

    The student inventors have applied for patents on their technology, and expect the E-Kaia to go on sale in December 2016.

    For high school leavers starting out in the working world, it is very important to learn particular skills and practise how to behave in an interview or how to find all internship(实习). In some countries, schools have programs to help students onto the path to work. In the United States, however, such programs are still few and far between.

    Research shows that if high schools provide career-related courses, students are likely to get higher earnings in later years. The students are more likely to stay in school, graduate and go on to higher education.

    In Germany, students as young as 13 and 14 are expected to do internships. German companies work with schools to make sure that young people get the education they need for future employment.

    But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world. Harvard Education school professor Robert Schwartz has criticized education reformers for trying to place all graduates directly on the four-year college track. Schwartz argued that this approach leaves the country's most vulnerable(易受影响的) kids with no jobs and no skills.

    Schwartz believed that the best career programs encourage kids to go for higher education while also teaching them valuable practical skills at high school. James Madison High School in New York, for example, encourages students to choose classes on career-based courses. The school then helps them gain on-the-job experience in those fields while they're still at high school.

    However, even for teens whose schools encourage them to connect with work, the job market is daunting. In the US， unemployment rates for 16-to-l9-year-olds are above 20 percent for the third summer in a row.

    “The risk is that if teenagers miss out on the summer job experience, they become part of this generation of teens who had trouble in landing a job,” said Michael, a researcher in the US.

    Many high school students consider a college education useless. Therefore, they choose not to go to college. If you're one of them, think again. Here are some reasons why you should go to college and receive a good education there.

    Schools and universities are the first sources of knowledge. We take that knowledge later on to build our careers after graduation. More knowledge will be gained after you start working, but without an education, that job will not be within easy reach. Knowledge leads to knowledge.

    While limited within the walls of the educational institutions, we openly explore other cultures of the world. We come to know that ours is not the only culture. Other cultures have valuable insights to share, enriching our own. Education also makes us want to travel and interact with various cultures, broadening our horizons.

    When there's a downturn (衰退) in the economy, those who attended college will be more likely to find a new job than those who only finished grade school and have a limited skills set. The more education you have, the more chances you will get to improve the quality of your life as you have a better job and earn a higher salary.

    When you're skillful and knowledgeable, you get to “rub knees” with people of similar backgrounds and tastes. It means a good education leads to excellent networking. Good networking can benefit you a lot in your later life.

    A good education makes you a more interesting person. You can talk about ideas and events instead of just other people and what's on sale in stores. An educated person doesn't gossip, having a preference to discuss ideas and listen to what other people have to say.

    Over the past couple of days, on our local Freecycle page there have been a lot of wanted posts, all from the same person, basically asking for everything you'd need to set up a house from scratch.

    One of the things they asked for was a queen-sized bed. At that time we just happened to have an extra one, so I messaged them. They immediately came in the afternoon. The people who came, two ladies and a man, are actually friends of another woman named Jenny who owned a young boy. This woman has escaped from a dangerous, violent relationship and these friends of hers are helping her and her son start over again, with everything from furniture to toothbrushes on their list of needs.

    While they were here, I also gave them one of our spare bookcase and some coffee cups. I even asked them to keep in touch in case they needed anything else—I have a way of connecting people with things. I offered the woman a cupboard we had as well; her friends just needed to see if there was a place and/or a need for it in their friend's new home.

    I was so excited to meet those loving people, who were obviously willing to help their friend. It was clear how protective they felt of this woman and her boy, how much they love her and wanted her to have a happy and safe life, and to spend even a few minutes with people like that is an experience I'll remember for a long, long time.

    A quick thank-you to all who have sent more donations over the last couple of days, as well as lovely messages of thanks and blessings. Sometimes it's hard to keep up with it all, but it's a problem I'm happy to have.
