    Nelson Mandela, South Africa's first black president, died on Decembr5, 2013 at 95.

    Mandela was born on July 18, 1918. He grew up in a poor village in South Africa. At school, Mandela learned about African history and the fight against racism(种族歧视).He wanted to help his countrymen. Later Mandela studied law at a university. He also joined a group that fought against apartheid(种族隔离).At that time, in South Africa, blacks were not allowed to use the same public toilets or chairs as whites, and they couldn't travel on the same buses as whites, either. Mandela hated this and he traveled all over South Africa and fought to end apartheid. As a result, he was put into prison(监狱) and stayed about 27 years there.

    On February 10, 1990, South African President F.W. de Klerk released(释放)Mandela from prison, and the two worked together to end apartheid. Three years later, they won the Nobel Peace Prize,

    In1994, Mandela became President of South Africa. One year later, he created the Nelson Mandela Children's Fund, a charity that helps poor South African children." Children are the future of our country," he said in an interview in2002. "They must be given love."

    Mandela served as President until 1999. He worked to improve housing and education for the country's large black population.

    Boyan Slat has one huge goal. It's a goal that could be good for people and a {#blank#}1{#/blank#} all over the world. Amazingly, it looks like he's going to m {#blank#}2{#/blank#}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{#blank#}3{#/blank#} 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{#blank#}4{#/blank#} to break down (分解).

    The p{#blank#}5{#/blank#} 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{#blank#}6{#/blank#} 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{#blank#}7{#/blank#} 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{#blank#}8{#/blank#} 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{#blank#}9{#/blank#} 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{#blank#}10{#/blank#} goes on for Slat. He hopes that the oceans will be free of plastic in about twenty or thirty years.
