He looked across the classroom at the drinking fountain. It was very close — only ten steps away. So， Ryan asked himself， “Why do some African children have to walk ten kilometres to get water every day？ And why is the water so dirty that it makes them sick？” Young Ryan thought，“Life is easy for me， but hard for those people. Why don’t I help？” 　　At first， his plan was to earn money to build a single well somewhere in Africa. He cleaned windows and did gardening for his family and neighbours. He soon reached his first target of $70， but when he gave the money to a charity， he was told that it actually cost $2，000 to build a well. Seventy dollars was only enough for a hand pump. Ryan understood that a hand pump wouldn’t help the children. What they needed was a well dug near their homes. 　　Two thousand dollars was a lot of money， but Ryan didn’t give up. He was determined to help other children have clean water. He started to ask for help from his classmates and neighbours and persuaded them to donate money. At the same time， a friend of Ryan’s mother helped make his story go public. After several months， Ryan had raised the $2，000，with which a well was built near a primary school in Uganda. The children at the school no longer needed to walk for hours to get water. They were grateful to him and invited him to visit. 　　In Uganda， Ryan at last saw the finished well with his own eyes. But that was not all. He also saw hundreds of delighted students who had turned out to welcome him. They sang and danced happily. Some even offered him food and gifts. At first Ryan was nervous， but soon a great warmth filled him.He really had made a difference for these children. He broke into a joyful smile. 　　Later， Ryan’s experience led him to set up a foundation to encourage more people to help. Many inspired people gave him their support. Ryan’s foundation continues to attract support from more and more people， so the work of building more wells can go on. Today， over 800，000 people in 16 countries across Africa have benefited from the life-changing gift of clean， safe water. 　　Now， as an adult， Ryan says that the question to ask is not “Why don’t I help？”， but “How can I help today？”.This insight grew from the determined attitude of a six-year-old boy who had the courage and perseverance to make his dream a reality. （选自外研必修三） 【写作素材】 1.情感描写 ①He was determined to help other children have clean water. ②He also saw hundreds of delighted students who had turned out to welcome him. ③At first Ryan was nervous，but soon a great warmth filled him. 2.人物描写 This insight grew from the determined attitude of a six-year-old boy who had the courage and perseverance to make his dream a reality. 3.定语从句 After several months，Ryan had raised the $2，000， with which a well was built near a primary school in Uganda. 4 / 4 学科网（北京）股份有限公司 $ 单元整合提升 【知识重温·提能力】 一、 1.parcel　2.jam　3.secondary　4.weed　5.chorus 6.cotton　7.washroom　8.rigid　9.forehead　10.housing 11.kettle　12.pan　13.plug　14.input　15.tune 16.contract　17.grant　18.criterion Ⅰ.1.deserving　2.platform　3.mail　4.dragged　5.shade 6.prays　7.uniform　8.jaw 二、1.disabled　2.resign　3.lately　4.consultation　5.stability Ⅱ.1.dusty　2.ripened　3.Lately　4.stability　5.chemistry 三、1.a chorus of　2.not to mention　3.take （...） for granted　4.relay to　5.pray that　6.be dying to do sth　7.make a big difference　8.in need of　9.the other day　10.adapt to　11.be relevant to ...　12.to be honest Ⅲ.1.The other day　2.To be honest　3.praying that 4.relay； to　5.take； for granted Ⅳ.1.was taking a walk in the park when 2.from where kiteflying spread to 3.Not only have they achieved great success in business 4 / 4 学科网（北京）股份有限公司 $
