I hope it will make lives easier, safer, and more fun. I believe science and technology will bring more surprises. 【亮点解析】 开篇简洁，迅速进入主题。 “Technology has greatly changed my daily life in many ways.”用现在完成时开篇，表明变化已经发生并持续至今。“in many ways”为下文分场景描述做好了铺垫。 按应用场景分类组织，条理清晰。 按“通信—学习—日常”三个板块逐一展开，每个板块先写应用再写帮助，结构一致，读者易于跟随。每个场景的表述形成了完整的“工具—功能—效果”链条：比如通信部分，“smartphone”（工具）→“send messages, make video calls, share photos”（功能）→“makes it easy to connect”（效果），信息完整，逻辑紧密。 功能与帮助一一对应，不分离。 “share photos instantly”对应“easy to connect”和“even when far apart”中的“远距离沟通”；“search for information and take online courses”对应“more interesting and convenient”；“navigation app”对应“avoid traffic jams”；“online shopping”对应“saving time”。每一个应用后面都紧跟其带来的好处，论证充分。 动词运用多样化。 “send messages”“make video calls”“share photos”“search for information”“take online courses”“avoid traffic jams”六个动词短语覆盖了通信、学习、出行、购物等多个场景，用词准确丰富。 “also”和“even when”等衔接词增强连贯性。 “even when we are far apart”对“stay in touch”进一步补充，强调距离不再是障碍；“also”用于连接日常需求中的两个例子——导航和购物；“which saves us a lot of time”中的which引导定语从句，补充网购带来的好处，句式有变化。 五、阶梯训练 （一）句子训练 Level 1 汉译英 1. 科学技术在很多方面极大地改变了我们的生活。 ____________________________________________________________ 2. 北斗是一个为全世界人民提供服务的导航卫星系统。 ____________________________________________________________ 3. 2020年，北斗三号完成并开始为全球提供服务。 ____________________________________________________________ 4. 高铁快速、干净、舒适，改变了中国人的出行方式。 ____________________________________________________________ 5. 我真的为科学技术方面的伟大成就感到自豪。 ____________________________________________________________ Level 2 句型仿写（参照例句完成句子） 句型 1：... is a system that ...（介绍科技系统） 例句： BDS is a navigation satellite system that provides services for people all over the world. （1）天宫空间站是一个让科学家在太空中做实验的平台。 ____________________________________________________________ （2）中国天眼是一个帮助科学家观测宇宙的射电望远镜。 ____________________________________________________________ 句型 2：... was completed in ... and began providing services.（描述完成与启用） 例句： BDS-3 was completed in 2020 and began providing services around the world. （1）天宫空间站于2022年完成并开始为科学家提供研究平台。 ____________________________________________________________ （2）这条高铁于2017年完成并开始为乘客提供服务。 ____________________________________________________________ 句型 3：With the help of ..., people can ...（描述科技的作用） 例句： With the help of BDS, people can find their way in the right direction. （1）在高铁的帮助下，人们可以更快地在城市之间旅行。 ____________________________________________________________ （2）在人工智能的帮助下，医生可以更好地诊断疾病。 ____________________________________________________________ 句型 4：It has changed the way people ...（描述带来的变化） 例句： High-speed rail has changed the way people travel in China. （1）智能手机改变了人们相互交流的方式。 ____________________________________________________________ （2）互联网改变了人们获取信息的方式。 ____________________________________________________________ 句型 5：A research team worked ... to ...（描述研发努力） 例句： A research and development team worked day and night to solve technological problems. （1）科学家们努力工作多年研发出北斗系统。 ____________________________________________________________ （2）工程师们夜以继日地工作完成这个项目。 ____________________________________________________________ 句型 6：I’m proud of ...（表达自豪感） 例句： I’m really proud of the great achievements in science and technology. （1）我为祖国的科技进步感到自豪。 ____________________________________________________________ （2）我为北斗系统的成功感到自豪。 ____________________________________________________________ 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：BDS is a navigation system. 升级句：BDS is a navigation satellite system that provides services for people all over the world. 1. 基础句：High-speed rail is fast. 升级句：____________________________________________________________ 2. 基础句：It helps people find their way. 升级句：____________________________________________________________ 3. 基础句：Scientists worked hard. 升级句：____________________________________________________________ 4. 基础句：The system is used for navigation. 升级句：____________________________________________________________ 5. 基础句：Technology changes our life. 升级句：____________________________________________________________ 6. 基础句：I am proud of these achievements. 升级句：____________________________________________________________ （二）篇章训练 根据提示，写一篇短文介绍一项中国的科技成就或工程项目 写作提示：假设你的学校正在举办“中国科技成就展”，请你写一篇短文介绍一项中国的科技成就或工程项目（如：北斗卫星导航系统、高铁、三峡大坝、中国天眼、空间站等）。 要点： 1. 这项成就或工程的名称； 2. 它的用途或重要性； 3. 它如何改变了人们的生活； 4. 你的感受。 要求：1. 语句通顺，逻辑清晰；2. 不少于80词；3. 可适当发挥。 _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 参考答案 Level 1 汉译英 1.
