A 【导语】本文主要介绍了互联网和社交媒体的发展：从过去用词语交流到如今通过视频、声音等形式分享生活，社交媒体像个人电视台，免费且便捷，让生活更方便，人们能轻松购物、出名。 【解析】1. 句意：随着科技的发展，互联网出现了。 此处表示“随着科技的发展”，with the development of“随着……的发展”是固定搭配；growth“成长”，instruction“说明”，protection“保护”，都不符合搭配。 2. 句意：于是人们有了其他和朋友分享生活的方式。 前文说过去只用文字，现在有了网络，是新的分享生活的“方式”，ways“方式、途径”符合语境；subjects“科目”，rules“规则”，problems“问题”，均不符合句意。 3. 句意：人们经常使用声音、视频和词语来表达他们想说的话。 使用多种媒介的目的是“表达”思想，因此选express。admire”欣赏”、stop“停止”、forget“忘记”不合逻辑。 4. 句意：他们只发布视频。 在社交媒体语境下，上传/发布视频用post最合适。buy“买”、sell“卖”、touch“触摸”不符合。 5. 句意：有人说社交媒体看起来像个人电视台。 looks like意为“看起来像”。seems like也可表示“似乎像”，但looks like更直观描述外形/功能。comes from“来自”、signs up“注册”错误。此处选looks like更常见。 6. 句意：所以任何人都可以不用付钱就把视频传到网上。 文中说大多数社交媒体是免费的，因此“不花一分钱”发布视频，选without。with“有”、by“通过”、for“为了”不符合。 7. 句意：有些人因为出色的短视频而出名。 制作优秀短视频的结果通常是“出名”，而不是直接变富或变懒。lazy“懒惰”、rich“富有”、tired“疲倦”不准确。 8. 句意：人们的生活因为互联网而变得便捷。 下文提到网购省时，体现的是“便利”，因此选convenient。simple“简单”、usual“通常”、boring“无聊”不符合。 9. 句意：过去人们必须走很远的路去市场买东西。 market意为“市场”买东西的地方是市场，符合常识。school“学校”、hospital“医院”、cinema“电影院”与购物无关。 10. 句意：现在人们可以用手机轻松买到他们想要的东西。 手机购物非常便捷，easily副词，修饰动词buy，表示“便捷的、容易地”。hardly几乎不”、slowly“缓慢地”、completely“完全地”不符合语境。 $Unit 3 Our digital lives 词汇专项过关 词汇基础练 词汇语境练 词汇语篇练 一、汉译英 英文 中文 英文 中文 单词 n. 网络 n. 洪水，水灾 n. 多媒体 n. 专家 adj. 可移动的 n. 付款，支付 v. 提醒注意，警告 n. 治疗，疗法 n. 数据 n. 公司 n. 路上行驶的车辆，交通 v. （人或事物）涌流，流动 adv. 平稳地，连续而流畅地 n. 笔记本电脑 n. 屏幕 n. 重量 adj. 数码的 adj. 社交的 n. （书面或口头的）信息 v. 采访 adj. 正面的 adj. 消极的 n. 影响 n. 意见，看法 n. （长篇）小说 n. 评论 n. 基础 n. 微处理器 n. 微芯片，芯片 adj. 主要的，重要的 n. 突破，重大进展 adj. 电子的 n. 软件 n. （application的缩写）应用程序，应用软件 n. 时代，纪元 v. 下载 adj. 微小的 短语 连接 给……带来重大变化 移动支付 以……为例 垃圾箱 社交媒体 亲自，自身 公众，大众 2、 词汇拓展（单词变形） 学科网（北京）股份有限公司1 / 5 学科网（北京）股份有限公司 1. payment——__________（v.）支付 2. warn——__________（n.）警告 3. treatment——__________（v.）治疗 4. smoothly——__________（adj.）平稳的，流畅的 5. weight——__________（v.）称重 6. social——__________（adv.）在社会上，善于交际的 7. electronic——__________（n.）电子器件，电子学 一、单词拼写 1.
