—I guess you should tell her it's not right.

    I find it really hard to write about my favourite invention, because there are so many things in my life that I could choose.1, I have chosen to write about a pen.

    Yes, I know that for most people a pen is boring, but. For2, it is a symbol of possibility (可能性). There are so many things you can do with a pen. You3write a novel or a song. Record information or draw a masterpiece (杰作).

    For me, a4is the beginning of something amazing. Every day, I write a new page with my pen, and I am5paving (铺设) a path for my future. I could get into Stanford University for medicine,6the Juilliard School for music. Maybe I will be a(n)7and change the world with my discoveries (发现). Maybe I'll8a musician and touch people's hearts with my music. Or perhaps I will be a writer and move people through words ... or a9and help children grow into the people they will become.

    There are so many possibilities as to what I will do with my life, but I10that with my pen in my hand, I will write a good future for myself. Tell me what future you will write for yourself!

    How old are you? Have you created anything useful? Do you know Kelvin Doe? Let me tell you something about him.

    Kelvin Doe is an African boy. Though he is very clever, his family is so poor that he can't go to school. When most teenagers are learning how to solve maths problems, Kelvin Doe is teaching himself to make batteries and generators (发电机) for his neighbourhood. Kelvin is only 22 years old, but has already created batteries and generators by himself. He used things he picked up around the house or from rubbish boxes to create them.

    "In my home town, we don't have much electricity and batteries are expensive," Kelvin said. So he decided to make batteries to light up people's homes. Kelvin also owns a radio station. He broadcasts news and plays music for the local people. The station gets its electricity from a generator also made by himself, He wants to help more families in his home town live a happy and comfortable life.

    A 22-year old British student has invented a mobile fridge that could save millions of lives across the world.

    Will Broadway's "Isobar" has been designed to keep vaccines(疫苗) at the ideal temperature while they are being sent in developing countries. And Will doesn't plan to make money from his creation. His purpose is to get vaccines to people who need them, which is why he won't be trying to get a patent(专利). Will's Isobar has won him the James Dyson Award that challenges young people to "design something that solves a problem".

    Present methods of transporting vaccines can lead to the vaccines freezing(冻住) before reaching their places in developing countries, but the Isobar keeps a temperature of 2 to 8 degrees for 30 days.

    Will's invention is expected to save the lives of 1.5 million people across the world, a number he says is "amazing". Having now finished college education, he is making an effort to take the Isobar into production. "I would be hands-on, all the way through it, knowing that it works," he says. "It's amazing to just give it a go, even in my back yard, and see the potential(潜能) of the technology."

    The product has been designed to transport vaccines, but already Will sees the possibility of other medical uses in the developing world and beyond. "Blood donations, organ transplants(器官移植)- if they get trapped in traffic, you still use cold bags that really aren't good enough for a long time," he says.

    There is also a possible, non-medical use of the Isobar. "It would be a great thing to take on a five-day trip where you have no power," he says. But he insists vaccine transportation is the primary function(功能) of his invention.
