When I was 13, my journey in a great valley changed my attitude towards the recording of a travel. During the trip, I was busy recording every event, name and place I came across. I felt proud to {#blank#}1{#/blank#} my time, keeping a {#blank#}2{#/blank#}description of my travels. On my last night there, after I {#blank#}3{#/blank#} the tent, I went out with diary in hand. The sky was clear with the bright moon, and the walls of the valley looked frightening behind their curtains of shadows（阴影）. The beauty of nature at dusk {#blank#}4{#/blank#} my heart entirely. I took out my pen right away... At that moment, I understood that the beautiful scenery I saw {#blank#}5{#/blank#} was more meaningful than the tiring words that I had {#blank#}6{#/blank#} in my diary. Since then I have {#blank#}7{#/blank#} only to keep a special thought or feeling in my diary. The unforgettable moments I {#blank#}8{#/blank#} would be the sweet and lasting memories for my life.

    The Father of JD Printing

    About twenty years ago, the surgeons at the Wilford Hull medical center working to separate a pair of conjoined(连体的) twins thought that only one would be able to walk after the operation. After a model of the girls' bone structure was {#blank#}1{#/blank#} using 3D printing, however, they found a shared upper leg bone to be bigger than expected and split it successfully, {#blank#}2{#/blank#} in both twins being able to walk. Now eighty and still working as chief technology officer of 3D Systems. Chuck Hull is enjoying some minor {#blank#}3{#/blank#} 31 years after he first printed a small black eye-wash cup using a new method of manufacturing known as 3D printing.

    At the time, he was working for a company that used UV light to put thin layers of plastic coats on tabletops and {#blank#}4{#/blank#}. He had an idea that if he could place thousands of thin layers of plastic on top of each other and then cut their shape using light, he would be able to form three dimensional objects. After a year, he {#blank#}5{#/blank#} a system where light was shone into a bottle of photopolymer – a material which changes from liquid to plastic-like solid when light shines on it – and traces the shape of one level of the object. Subsequent layers are then printed until it is {#blank#}6{#/blank#}.

    After patenting the invention, he set up 3D Systems, {#blank#}7{#/blank#} getting $6m (£3.5m) from a Canadian investor. The first {#blank#}8{#/blank#} product came out in 1988 and proved a hit among car manufacturers, in the aerospace sector and for companies designing medical equipment. The possibilities appear endless – from home-printed food and medicine to {#blank#}9{#/blank#} that pictures of objects be able to be taken in shops and then recreated using plans downloaded from the Internet Although deliberate in his responses, there is one moment when the {#blank#}10{#/blank#} spoken Chuck Hull tells of his surprise about what exactly his creation was capable of achieving.

The Floating School

    Life on the islands can feel a bit isolated due to a lack of electricity and internet connectivity.

    Although some of the islands have primary schools, most young people must travel to the larger islands or to the mainland to attend high school. Schools on the islands follow the {#blank#}1{#/blank#} curriculum (课程). They don't teach subjects such as maritime skills, swimming or local fishing traditions, and so the curriculum isn't always {#blank#}2{#/blank#} with students' everyday life.

    So, we {#blank#}3{#/blank#} the Floating School after winning funding through a US State Department grant competition called Seeds for the Future. Before we started the school, we spoke with young people, community leaders and teachers on the islands to find out the topics young people are most interested in. We also learned about the various {#blank#}4{#/blank#} of students and young people who don't go to school. Thus, we {#blank#}5{#/blank#} our own non-formal educational programme that fits with the context of life on the islands. For example, those working in fishing have responsibility {#blank#}6{#/blank#} the marine life, so we teach environmental protection and discourage destructive fishing practices.

    The Floating School is a wooden boat that can {#blank#}7{#/blank#} up to twenty people and it goes to the students, not the other way around -- we use it to transport educational materials, tools, and teachers to young people living on the islands. Our teachers are local young {#blank#}8{#/blank#}— so far we have had journalists, photographers, computer engineers and musicians — and students who want to {#blank#}9{#/blank#} their skills.

    At first, many of the young people thought the Floating School would be the same as their schools on the islands. They had thought of the teachers to be {#blank#}10{#/blank#}. But our students learn through art, media and literature. They don't have to wear uniforms or shoes, and the teachers treat the students as equals, without judging them. This means our students can be themselves.
