Write an article about how someone came up with a great idea to solve a problem. Step1 Plan Note down key information in the graphic organizer. Step 2 Write Write an article about the great idea.Use the information in step1 to help you. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ I wrote about how someone came up with a brilliant idea to solve a problem, and how this idea has influenced our lives. I used different sentence types in the article. I used the words and expressions I learnt in this unit. I used correct spelling, grammar and punctuation. Step 3 Check and revise Tick (√) the boxes to check your writing, and then revise it. Many years ago, malaria spread widely across the world. This serious illness killed a large number of people every year. However, common medicines were useless and people had no good ways to fight it. Tu Youyou, a great Chinese scientist, decided to change the situation. She spent plenty of time researching traditional Chinese medicine and tried hundreds of plants again and again. She never gave up even when she met difficulties. At last, she successfully discovered artemisinin to treat malaria. Her amazing discovery has saved millions of lives all over the world. She won the Nobel Prize for her great work. Her story tells us that great achievements always come from long-term hard work. Hundreds of years ago, people felt confused about a common natural phenomenon. Nobody could explain why all things fell down to the ground instead of flying up. It remained a big puzzle for a long time. One day, Isaac Newton, a famous British scientist, saw an apple fall from the tree. This small scene gave him a new thought. He kept thinking and doing research day after day. Finally, he found out the existence of gravity, which pulls all things toward the Earth. This great finding opened a new door for physics. It explained many natural laws clearly. Up to now, people still learn and make use of his important discovery in scientific study. 回顾总结 06 29 一、复习和总结描述一位伟大思想的词汇和句型。 二、通过思维导图，我们学习关于“如何描述一个伟大的思想” 。 三、用所学的知识完成一篇写作任务。 课堂小练 07 31 find out the truth be made of/from think of a brilliant idea be outstanding in come up with a new way to… get an idea from… change people’s lives have a lasting impact on spend a lot of time doing… benefit the whole world 一、翻译短语 1.查明真相 2.由…… 制成 3.想出绝妙的主意 4.在…方面表现出色 5.想出做…的新方法 6.从…得到启发 7.改变人们的生活 8.对…产生深远影响 9.花大量时间做 10.造福全世界 一、描述背景与困境 1.Long ago, people were troubled by a hard problem. 很久以前，人们被一道难题所困扰。 2.People had no useful ways to get out of the trouble. 人们找不到可行的办法摆脱困境。 3.Traditional ways could hardly solve the problem. 传统方法难以解决这个难题。 二、介绍人物与萌生想法 A great scientist came up with a brilliant idea. 一位伟大的科学家想出了一个绝妙的主意。 2.He got an idea from a small daily thing. 他从一件日常小事中得到了启发。 3.She kept thinking and tried many times. 她不断思考，反复尝试。 4.He is outstanding in scientific research. 他在科研方面十分出色。 三、讲述过程与解决办法 1.Finally, he found out the secret of nature. 最终，他揭开了大自然的奥秘。 2.They thought of a new way to deal with the problem. 他们想出了解决问题的新方法。 3.His creative idea turned out to be very useful. 这个富有创意的想法收效极佳。 四、阐述影响与意义 1.This amazing idea completely changed people's lives. 这个了不起的想法彻底改变了人们的生活。 2.It has left a lasting influence on the whole world. 它对全世界都产生了深远的影响。 3.People still benefit a lot from his idea today. 时至今日，人们依旧从他的想法中获益良多。 4.His discovery helps us understand the world much better. 他的发现让我们能更好地认知世界。 五、总结感悟 1.Brilliant ideas come from careful watching and hard work. 精妙的想法源于细致的观察与不懈的努力。 2.We should hold on and never give up when facing difficulties. 面对困难，我们应当坚持不懈、永不言弃。 实战演练 诸多伟大的想法，往往源自现实中遇到的难题。请选取一则事例，撰文讲述：有人凭借独到的智慧与巧妙的办法，最终攻克难题的经历。文章包含以下内容： ● What was the problem to be solved? ● Who came up with a brilliant idea to solve the problem? ● How was the problem solved? ● What influence has this idea had on our lives? A long time ago, people mainly used stone axes to cut wood. This work was not only slow but also very tiring. Everyone wanted a better tool to make the job easier, yet nobody came up with a good idea. One day, Lu Ban was walking in the mountains. A sharp wild leaf cut his finger. He looked closely at the leaf and got great inspiration. Then he created a new tool called the saw with sharp teeth. It worked far better than axes. This brilliant invention brought great changes to people’s work. For thousands of years, the saw has been widely used all over the world. It truly shows that great ideas come from careful observation around us. Hundreds of years ago, the king had a beautiful gold crown. He doubted it was not made of pure gold, but no one could find a way to check it without damaging the crown. Archimedes decided to solve the problem. One day when he took a bath, he saw water run over. He suddenly thought of a useful method. He realized the displaced water could tell the object’s size. With this idea, he found out the truth successfully. His discovery of the buoyancy principle became an important physical law. It has had a lasting influence on science and daily life. His story tells us to think wisely when facing difficulties. Thank you！ 39 $
