It can change its size: folded small enough for a pocket, and big enough to shelter two people when opened. It has a special sensor that sends phone warnings before rain comes, reminding me to take it. I love it for its convenience and smart design. It keeps me dry on rainy days. I hope this invention can come true one day. 【亮点解析】 开篇一句说明“解决什么问题”。 “to solve the trouble of sudden rain”直接点明了发明的目的——应对突如其来的降雨。生活中忘带伞被雨淋是人人都有过的经历，这个问题真实且普遍，读者马上能理解这项发明的价值。 两个特点清晰具体，可操作性强。 特点一：“change its size”——能伸缩；“folded small enough for a pocket”进一步说明收缩状态有多小；“big enough to shelter two people when opened”说明展开后有多大。从折叠到展开、从一人到两人，信息清楚。特点二：“has a special sensor that sends phone warnings before rain comes”有感应器；“reminding me to take it”补充了提示功能的目的。两个特点一个管“空间”（大小），一个管“时间”（预警），分工明确。 原因与特点对应，不空泛。 “I love it for its convenience and smart design.”——其中的“convenience”对应可折叠收纳的便捷性，“smart design”对应提前预警的智能性。原因从特点中来，前后呼应。“It keeps me dry on rainy days.”用最朴实的语言说最根本的好处——不被雨淋，回归发明初衷。 结尾简短真诚。 “I hope this invention can come true one day.”表达梦想成真的愿望，作为“dream invention”的收尾自然贴切，不堆砌大话。 五、阶梯训练 （一）句子训练 Level 1 汉译英 1. 造纸术在东汉时期由蔡伦改进。 ____________________________________________________________ 2. 指南针帮助水手在海上找到正确的方向，让长途航行更加安全。 ____________________________________________________________ 3. 活字印刷被用来更快、更便宜地生产书籍，帮助知识更快传播。 ____________________________________________________________ 4. 电灯泡由托马斯·爱迪生在1879年发明，它给人们在夜晚带来了光明。 ____________________________________________________________ 5. 它是最重要的发明之一，改变了世界，让我们的生活更加便捷。 ____________________________________________________________ Level 2 句型仿写（参照例句完成句子） 句型 1：... was invented by ... in ...（介绍发明） 例句： The light bulb was invented by Thomas Edison in 1879. （1）电话由亚历山大·格拉汉姆·贝尔在1876年发明。 ____________________________________________________________ （2）汽车由卡尔·本茨在1885年发明。 ____________________________________________________________ 句型 2：It is used for ...（描述用途） 例句： The compass is used for finding directions. （1）电灯泡被用来在夜间照明。 ____________________________________________________________ （2）活字印刷被用来更快地印刷书籍。 ____________________________________________________________ 句型 3：It is made of / from ...（描述材料） 例句： Paper is made from wood and other materials. （1）这张桌子是由木头制成的。 ____________________________________________________________ （2）这把椅子是由竹子制成的。 ____________________________________________________________ 句型 4：Before it was invented, people had to ...（描述发明前的困难） 例句： Before the light bulb was invented, people had to use candles or oil lamps. （1）在电话被发明之前，人们不得不通过书信远距离交流。 ____________________________________________________________ （2）在指南针被发明之前，水手们不得不依靠星星导航。 ____________________________________________________________ 句型 5：It took ... years to ...（描述耗时） 例句： It took the team many years to develop the new technology. （1）建造这座桥花了5年时间。 ____________________________________________________________ （2）完成这个项目花了工程师们3年时间。 ____________________________________________________________ 句型 6：Without it, people couldn’t ...（描述重要性） 例句： Without the light bulb, people couldn’t work or read at night. （1）没有电话，人们就不能远距离通话。 ____________________________________________________________ （2）没有指南针，水手们在海上就容易迷失方向。 ____________________________________________________________ Level 3 句子升级 要求：参照下方示例，将基础句升级为内容更丰富、表达更高级的句子。 示例： 基础句：Paper was invented by Cai Lun. 升级句：Paper-making was improved by Cai Lun during the Eastern Han Dynasty. 1. 基础句：The compass was important. 升级句：____________________________________________________________ 2. 基础句：It was used for printing. 升级句：____________________________________________________________ 3. 基础句：The light bulb was invented in 1879. 升级句：____________________________________________________________ 4. 基础句：It is a great invention. 升级句：____________________________________________________________ 5. 基础句：Paper is made from wood. 升级句：____________________________________________________________ 6. 基础句：The invention helped people. 升级句：____________________________________________________________ （二）篇章训练 根据以下提示，写一篇关于如何成为发明家的短文 写作要求： 请你以“How to Become an Inventor”为题，写一篇英语短文，介绍如何成为一名发明家。内容包括： 1. 从发现问题开始； 2. 制定一个好的计划； 3. 实施计划并克服困难； 4. 永不放弃并坚持努力。 注意：不少于70词；可适当运用本单元所学词汇与表达。 How to Become an Inventor _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 参考答案 Level 1 汉译英 1.
