Unit 2 Making a Difference
【话题导入】
As the old Chinese saying goes，“Humanity's most fundamental① relationship is with what we eat.”
Although food has played an important part in② Chinese culture for years，hunger had been a huge problem in the country until the 1970s.
However，the Chinese scientist Yuan Longping helped to fix③ this problem.
Yuan devoted himself to conducting research on④ rice in his life. In 1964, he discovered a natural hybrid (杂交的) rice plant. Then, he focused on developing high yield (高产的) hybrid rice varieties. These varieties now account for⑤ about two thirds of China's rice crop, according to China News.So, it's no wonder that he's known as the “Father of Hybrid Rice”．
And thanks to China's Belt and Road Initiative⑥，Yuan's hybrid rice is helping to solve food problems around the world.Indeed, according to Xinhua News Agency, hybrid rice plants in Kenya produce four to five times more rice than the country's regular rice plants.
On Sept.8, 2018, Yuan, together with⑦ two other scientists, won China's 2018 Future Science Prize for his continuous⑧research on rice.
On the eve of the 70th anniversary⑨ of the founding of the People's Republic of China, the 90 year old agricultural scientist was awarded⑩ the Medal of the Republic for his work on producing a hybrid variety of rice that has a much higher yield of grain.
Despite his great knowledge，Yuan understood that even the wisest people should still be open to new things.“The farmers of our country possess rich experience in planting rice，” he said.“We should learn from them.”

【人物小传】
瑞安·希里杰克(Ryan Hreljac)1992年7月出生在加拿大的一个普通家庭。“瑞安的井”事件后，他被人们称为“加拿大人的灵魂”，被评选为“北美洲十大少年英雄”。“瑞安的井”基金会是一个国际资助基金会，于2001年3月正式成立。“瑞安的井”基金会已经为非洲多个地区解决了用水问题。

The Well that Changed the World
As a six year old Canadian schoolboy, Ryan had trouble believing① the words spoken by his teacher that many people in developing African countries couldn't get enough clean water. He looked across the classroom at the drinking fountain②. 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？[1] 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？”
[1]本句是“so...that...”结构，that引导结果状语从句；makes them sick为“make＋宾语＋宾补”结构。
At first, his plan was[2] to earn③ money to build a single well somewhere in Africa. He cleaned windows and did gardening④ for his family and neighbours. He soon reached his first target⑤ 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 pump⑥. Ryan understood that a hand pump wouldn't help the children. [3]What they needed was a well dug near their homes.
[2]不定式短语to earn money在句中作表语；“to build a single...Africa”作目的状语。
[3]“What they needed”是主语从句，What在从句中作宾语；过去分词短语dug near their homes作后置定语，修饰a well。
[4]Two thousand dollars was a lot of money, but Ryan didn't give up. He was determined to⑦ help other children have clean water. He started to ask for help from his classmates and neighbours and persuaded them to⑧ donate⑨ money. At the same time, a friend of Ryan's mother helped make his story go public⑩. After several months, Ryan had raised the $2，000, [5]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.
[4]表示时间、距离、长度、价值、金额、重量等的可数名词复数作主语时，常被看作整体，谓语动词用单数形式。
[5]此处是“介词＋which”引导的非限制性定语从句，修饰先行词the $2，000。
In Uganda, Ryan at last saw the [6]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 .
[6]过去分词finished作前置定语，修饰well。
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 [7]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 .
[7]此处是不定式作后置定语，修饰the question。

改变世界的井
6岁的加拿大男生瑞安听老师说，非洲的发展中国家有许多人没办法获得足够的干净的水，他对此感到难以置信。他望向了教室另一边的饮水机。距离很近，只有10步远。于是，瑞安问自己：“为什么有些非洲孩子每天不得不步行10公里去取水？为什么水会那么脏，以至于让他们生病？”小瑞安想：“生活对我来说很简单，但对非洲那些人来说却很艰难。我为何不伸出援助之手？”
起初，他的计划是赚钱，然后在非洲某个地方打一口井。他为家人和邻居擦玻璃，打理花园。他很快就实现了挣得70美元的第一个目标，但当他把这笔钱捐给一家慈善机构时，却被告知打一口井实际上要花费2 000美元。70美元只够买一个手摇泵。瑞安知道，一个手摇泵无法帮到那些孩子。他们需要的是在他们家附近打的一口井。
2 000美元是一大笔钱，但瑞安没有放弃。他决心要帮助其他孩子获得干净的水。他开始向同班同学和邻居寻求帮助，说服他们捐款。与此同时，瑞安妈妈的一个朋友帮忙宣传他的故事。几个月后，瑞安已筹集了2 000美元，用这笔钱在乌干达一所小学附近打了一口井。学校的孩子们无须再步行数小时去取水。他们很感谢瑞安，并邀请他前来做客。
在乌干达，瑞安终于亲眼看到了那口打好的井。但这还不是全部。他还看到数百名兴高采烈的学生出来迎接他。他们高兴地唱歌、跳舞。甚至有人为他送上了食物和礼物。瑞安起初还很紧张，但很快他的心里就充满了暖意。他真的为这些孩子带来了生活的改变。他突然开心地笑了起来。
后来，基于这次经历，瑞安设立了一个基金会，鼓励更多的人提供帮助。许多受到鼓舞的人都来支持他。瑞安的基金会不断吸引着越来越多的人的支持，因而打井的工作得以继续。今天，非洲16个国家的80多万人已受益于清洁、安全的水，这一改变生活的礼物。
现在，作为一个成年人，瑞安说要问的问题不是“为什么我不去帮助(别人)？”，而是“今天我该如何帮助(别人)？”。这种顿悟源于一个态度坚定的6岁男孩，他有勇气和毅力实现自己的梦想。
