Boyan Slat has one huge goal． It's a goal that could be good for people and a（1）　　all over the world． Amazingly， it looks like he's going to m（2）　　 his goal．

    When he was 16， Dutch engineering student Slat was on vacation in Greece， and he started to think about all the rubbish that is p（3）　　 onto beaches by water． The oceans around the world are all of plastic ﹣millions of tons of plastic． Unfortunately， plastic doesn't just disappear． It takes c（4）　　 to break down （分解）．

    The p（5）　　 situation of the oceans is bad and worrying and Slat wanted to do something to change it． So he made it a personal goal to clean up the rubbish in the world's oceans．

    Slat started with an idea for an unusual m（6）　　 to "catch" the plastic floating（漂浮）in the water using the natural energy of the ocean． He left school in 2013 to begin work on his project The Ocean Cleanup． Soon， the project r（7）　　 a lot of attention．

    A year later，he was leading a team of 100 scientists and engineers working on the invention．Slat needed money for this，so he started asking people to d（8）　　to his project online and raised over ﹩ 2 million!

    Soon after，Slat was named a "Champion of the Earth" by the United Nations for his meaningful and v（9）　　work． It' s the most important title the UN gives to people helping the environment． The Ocean Cleanup also won several awards （奖项） for having one of the best inventions of 2015． But the d（10）　　 goes on for Slat． He hopes that the oceans will be free of plastic in about twenty or thirty years．
