Unit 5 Revealing nature Developing ideas Language points 课件 -2025-2026学年高二英语外研版选择性必修第一册

该高中英语课件围绕“植物交流的秘密”主题，结合“as well as”“be said to have done sth.”等语法点及detect、click等词汇，通过文化故事（如会说话的树传说）导入，引导学生从传说过渡到植物交流的科学探究（化学信号、声音、菌根网络），语言点作为学习支架辅助文本理解。 其亮点在于融合语言能力与思维品质，通过语法详解（如as well as的两种含义及就远一致原则）、词汇语境化例句（detect/detective对比）和科学文本分析（植物交流机制），培养学生语言运用与逻辑推断能力。采用“文本解读-语言点剖析-练习巩固”模式，学生能提升综合语言能力与科学思维，教师可借助系统支架优化教学流程。

Some plants make noises with their roots. Corn and chilli plants do this. They also “listen” to the noises from other plants. A chilli plant can tell if a neighbouring plant is helpful, or unfriendly. Some trees make clicking noises when there is not enough water, indicating drought is arriving. More surprisingly, plants also use sound to communicate. (para. 4) Most surprisingly of all, plants have an amazing system of communication that can link nearly every plant in a forest. (para. 5) eg. “What did you say to my animals?” said the emperor, (astonish). eg.

Most surprisingly of all, plants have an amazing system of communication that can link nearly every plant in a forest. Scientists call this system the “wood wide web”. It is in some ways similar to the Internet we use. While the Internet is a worldwide network of computers linked by cables and satellites, the wood wide web is linked underground by fungi. This fungal network links the roots of different plants to each other. Using the wood wide web, plants can share information and even food with each other. For example, some pine trees can send food to smaller pine trees to help them grow. But just like our own Internet, the wood wide web has its own version of “cybercrime”. Plants can steal food from each other, or spread poisons to attack other plants. Perhaps one day scientists will learn how to create a “firewall” to help prevent these attacks within the wood wide web. link ... to/with 把...和...联系起来 call sb. sth. 称呼某人某物 be similar to 与...相似 in some ways 在某些方面 Scientists are learning more every day about the secret ways in which plants talk to each other. (para. 6) eg. Can you tell me the way you use to solve the problem. eg. Can you show me the way you did it. which/ that in which/ that Scientists are learning more every day about the secret ways in which plants talk to each other. Who knows? Maybe one day we will know enough about plant communication to be able to “talk” with them ourselves. See you next class! 13 $
