外研版高中英语选择性必修第二册 Unit 4 Breaking boundaries 单元写作任务专项训练 本单元的写作任务是写一篇人物介绍或关于“突破”的短文(profile / short passage)。要求文章包含以下部分: 边界(The boundary):说明被突破的是技术极限、学科界线还是心理设限;突破(How it was broken):写清关键的做法、数据或转折点;意义(Why it matters):说明这次突破改变了什么,以及它给普通人的启示。 在动笔之前,教材为本单元的写作提供了充分的输入与铺垫。阅读输入:本单元的语篇介绍了多个“打破边界”的案例——跨学科合作、深海与太空探索、以及被长期认为“不可能”的纪录被刷新。教材引导学生区分“事实陈述”与“意义评价”,并注意数据的准确性。 语言输入:教材引导学生关注科技与探索词汇(boundary / breakthrough / limit / evidence / launch)、说明突破的句式(It was not until... that... / This made it possible to...),以及评价意义的表达(What matters most is...),并提示介绍人物时要选一个关键事件展开。 写作输出:教材设置了“写一位打破边界的人/一次突破”的写作任务——学生先列出时间线与关键数据,再按“边界—突破—意义”的顺序成文,最后制作一张人物或事件卡片。本单元的写作任务旨在培养学生运用边界—突破—意义的结构说明创新的能力,学会尊重事实、准确表达,并敢于质疑“不可能”。 ★真题写作迁移(高考英语真题改编) 假定你是李华,你校英文报 “Breaking Boundaries” 专栏正在征稿。请你写一篇短文,介绍一次人类探索未知的壮举,内容包括: (1)探索的背景; (2)这次探索的经过; (3)它的意义与你的感受。 注意: (1)写作词数应为 80 个左右。 (2)请按如下格式在答题纸的相应位置作答。 Three Hours at the Bottom of the Sea ★单元写作强基(原创) 假定你是李华,你班英语课要分享“我打破的一次边界”。请你写一篇短文,讲述一次挑战自己“不擅长”的经历,内容包括: (1)你原本的“边界”; (2)你如何尝试; (3)结果与你的认识。 注意: (1)写作词数应为 80 个左右。 (2)请按如下格式在答题纸的相应位置作答。 The Wrong Side of the Line ★写作主题提升(原创) 假定你校将举行以 “Boundaries Are Questions” 为主题的英语演讲比赛。请你写一篇演讲稿参赛,内容包括: (1)边界是谁画的; (2)一个打破纪录的例子; (3)你的呼吁。 注意: (1)写作词数应为 80 个左右。 (2)请按如下格式在答题纸的相应位置作答。 Hello, everyone, Thank you! ★高考模拟演练(原创) 假定你是李华,你的英国朋友 Chris 来信询问中国科学家取得的突破。请你回信,内容包括: (1)一项突破; (2)它的科学价值; (3)你的感受。 注意: (1)写作词数应为 80 个左右。 (2)请按如下格式在答题纸的相应位置作答。 Dear Chris, Yours, Li Hua 写作专项练习 第 页 共 页 学科网(北京)股份有限公司 参考范文 ★真题写作迁移(高考英语真题改编) One possible version: 范文词数 85 Three Hours at the Bottom of the Sea In 1960, two men reached the bottom of the Mariana Trench. Nobody returned for fifty-two years. In 2012, film director James Cameron went down alone in a submarine he had helped design. He spent three hours on the seafloor, collecting samples and filming creatures that had never been seen. The pressure outside was enough to crush steel. What stays with me is not the record but the patience: years of testing, and a willingness to go first. ★单元写作强基(原创) One possible version: 范文词数 84 The Wrong Side of the Line Our art teacher once asked us to draw with the hand we do not normally use. Mine was my left, and the pencil felt like a stranger. My lines were shaky and my proportions wrong. Halfway through, I stopped trying to be neat and began to enjoy the crooked shapes. The result was the first drawing I had ever liked. The boundary I crossed was not in my hand but in my idea of what counted as good. ★写作主题提升(原创) One possible version: 范文词数 83 Boundaries Are Questions Hello, everyone. A boundary is usually a line someone drew before we arrived. For centuries people said the four-minute mile was impossible. In 1954 Roger Bannister ran it in 3:59, and within two months another runner did the same. The limit had been physical, but the barrier had been mental. What changed was not the clock but the belief, and once one person crossed it, others followed. So when someone says “that's impossible”, ask who drew the line. Thank you! ★高考模拟演练(原创) One possible version: 范文词数 82 Dear Chris, You asked about breakthroughs made by Chinese scientists. I would mention the quantum satellite Micius. Launched in 2016, it sent entangled photons from space to the ground and later held the first quantum video call. In 2017 it sent entangled particles over 1,200 kilometres—far beyond what ground cables could do. The work may one day make communication almost impossible to spy on. I find the idea strange and beautiful: two particles, far apart, still answering each other. Yours, Li Hua 写作专项练习·参考范文 第 页 共 页 学科网(北京)股份有限公司 $
