4.The online shopping festival has been held for more than 10 years. 5.The damage that online games do to teenagers has been widely discussed recently. 七、单元主题写作（模板 + 满分范文） 1. 高频考情 本单元核心写作话题：互联网的利弊、如何合理使用网络、互联网对学习 / 生活的影响，为高一月考 / 期中期末高频议论文考点。 2. 三段式通用模板 开头段：引入话题，亮明核心观点 主体段：分点论述（利 / 弊 2-3 点，用本单元词汇句型） 结尾段：总结观点，发出倡议 3. 满分范文（贴合单元考点，100 词左右，高一适配） 题目：以 “Advantages and Disadvantages of the Internet” 为题，写一篇短文，谈谈互联网的利弊及你的看法。 Advantages and Disadvantages of the Internet There is no doubt that the Internet has changed our life greatly.
