选择性必修第一册 Unit 5 Revealing Nature 第2课时（Word教师用书）-【创新方案】2025年高考英语一轮总复习（外研版2019）

第2课时——强化表达功·写作短板的专项补弱 while连接并列句，表示对比或转折 while用作并列连词，表示前后分句的对比或转折，意为“然而，可是”。此外，while通常用作从属连词，引导状语从句： (1)引导时间状语从句，表示“当……时候”；(2)引导条件状语从句，表示“只要”；(3)引导让步状语从句，表示“尽管；虽然”，此时只用于句首。 |先|学|通|(通过句子变换把握句式特点)　 ①The Internet is of great help to us.But I don't think it is a good idea to spend too much time on it. →While_the_Internet_is_of_great_help_to_us,_I don't think it is a good idea to spend too much time on it. ②Every day we have the choice of building a fence or a bridge.One leads to separation and anger.The other leads to openness and friendship. →Every day we have the choice of building a fence or a bridge.One leads to separation and anger while_the_other_leads_to_openness_and_friendship. |再|写|美|(通过句子仿写做到运用自如)　 ③只要我们紧密地团结在一起，就一定能克服这些困难。 We can surely overcome these difficulties while_we_are_closely_united. ④此时，整个森林都醒来了。月光渐渐淡去，风儿歌唱，迎接黎明的到来。 At this moment, the whole forest woke up.The moonlight was fading while_winds_were_singing welcome to the dawn. 赏修辞之美 This happens when a plant, say a bean plant, gets attacked by insects. The plant releases tiny amounts of chemicals from the leaves that are being eaten. This is like a warning, or a call for help: “I'm being attacked！” 写法领悟：文中作者使用了直接引语，采用了拟人的修辞手法，形象地说明了植物利用化学物质进行交流的现象，使描述更生动形象，更利于突出表达的感情色彩，增强语言的亲切感。 [针对练笔]　(依据提示完成句子) I was very happy and could hear_the_birds_singing_in_the_woods.(拟人修辞) 我很高兴，能听到鸟儿在树林里唱歌。 [命题导向] 本单元主题是“认识与探索自然”，属于人与自然的主题语境。针对此类主题，高考在命制试题时一般会以活动报道或征文投稿为载体，介绍某一次探索自然、认识动植物的活动，如2023年浙江1月高考考查的活动报道“认识我们身边的植物”。此类命题旨在激发学生探索自然的兴趣，引发对自然界奥秘的思考和敬畏，进而理解人与自然和谐相处的重要意义。同时，引导学生养成不断探究、不断创新的思维意识。 构建语义场 (一)探索自然 1．be fascinated by　　　　 被……吸引 2．samples of the plants and animals 动植物样本 3．a variety of new species 各种各样的新物种 4．the spirit of scientific exploration 科学探索精神 5．reveal nature's secrets 揭示大自然的奥秘 6．be renowned worldwide for their unique biodiversity 以其独特的生物多样性而闻名于世 7．Earth is home to millions of different species. 地球是数百万不同物种的家园。 (二)发现自然 1．more surprisingly 更不可思议的是 2．a theory of evolution 进化论 3．one of the most important scientific discoveries 最重要的科学发现之一 4．adapt to their changing environments 适应不断变化的环境 5．evolve into many new species进化成许多新物种 6．hope to learn more about ...希望进一步了解…… 7．It has been known for some time that plants use chemicals to communicate with each other. 人们早就知道植物可以利用化学物质进行交流。 平时勤练笔 写作任务——基础写作的建模训练 [题目]　假定你是李华，近日你校组织了一次去中国国家植物园(China National Botanical Garden)的研学旅行。请你给校报“英语天地”写一篇报道。内容包括： 1．活动目的及内容；　2.你的收获或感受。 注意：1.写作词数应为80左右； 2．可以适当增加细节，以使行文连贯。 [构思与要点表达] 第一部分：活动目的 [从教材中学]　To best survive in their environment, each species has developed its own unique physical characteristics.
