厦门灯塔 · 第180期FT精读
上周，字节跳动开始在海外卖AI技术了——不是TikTok，而是TikTok背后的”秘密配方”。
这条新闻对咱们学英文有什么用？大量的商业/科技类高频词汇，恰好是中高考和雅思作文最缺的那类词。
今天从这篇FT报道（原文链接）里挑 4个 顶级实用表达，让你下次写”科技改变生活”或者”公司发展”类作文时，立刻拉开和同学的差距。
原文段落
ByteDance is selling some of the artificial-intelligence technology that powers its viral video app TikTok to websites and apps outside China, as it broadens its revenue streams ahead of a long-anticipated initial public offering.
A new division called BytePlus offers businesses the chance to tap some of TikTok’s secret ingredient: the algorithm that keeps users scrolling by recommending them videos that it thinks they will like.
The international debut of BytePlus follows the launch of a similar business-to-business service in China.
字节跳动正向中国以外的网站和应用出售其高人气视频应用TikTok背后的一些人工智能技术，其背景是该公司在各方期待已久的首次公开发行之前拓宽营收来源。名为BytePlus的新部门让企业有机会利用TikTok的一部分秘诀。BytePlus在国际市场亮相之前，字节跳动已在中国推出类似的B2B服务。
四个值得学的表达
1. power — 驱动、提供动力
原文出处： “the artificial-intelligence technology that powers its viral video app TikTok”
为什么好： 大多数中国学生写”驱动”只会用 drive（The technology drives the development…）。power 作动词，原意是”给……供电”，引申为”为某事物提供核心动力”。用在科技类描述中，语气比 drive 更精准、更地道。
| 学生写法 | 升级写法 |
|---|---|
| The technology drives the app. | The technology powers the app. |
| What makes this platform so popular? | What powers this platform’s popularity? |
| AI is the key factor behind smart education. | AI powers the transformation of smart education. |
例句： Machine learning algorithms power the recommendation system behind most social media platforms today.
2. tap (into) — 利用、获取
原文出处： “offers businesses the chance to tap some of TikTok’s secret ingredient”
为什么好： use 太普通，take advantage of 太长。tap（或 tap into）表示”接入并利用一个资源”，比 use 更生动，比 utilize 更自然。在商业议论文中特别好用——“利用市场潜力""利用新兴技术”都用它。
| 学生写法 | 升级写法 |
|---|---|
| Companies can use this technology. | Companies can tap into this technology. |
| We should take advantage of online resources. | We should tap into online resources. |
| The program helps students use their potential. | The program helps students tap into their full potential. |
例句： To succeed in the digital age, businesses must learn to tap into the power of data analytics.
3. broaden — 拓宽、扩大（范围）
原文出处： “as it broadens its revenue streams ahead of a long-anticipated IPO”
为什么好： broaden 不是新词，但大多数学生只用它配 horizons（broaden one’s horizons）。其实它能搭配的东西远不止”视野”——broaden one’s skill set / broaden access to education / broaden the range of services。比 widen 更正式，比 expand 更侧重”横向拓展”。
| 学生写法 | 升级写法 |
|---|---|
| The company wants to increase its income. | The company wants to broaden its revenue streams. |
| Students should learn more skills. | Students should broaden their skill sets. |
| The government provided more job opportunities. | The government broadened access to employment opportunities. |
例句： International exchange programs help students broaden their perspectives and develop cross-cultural communication skills.
4. debut — 首次亮相、首秀
原文出处： “The international debut of BytePlus”
为什么好： debut 源自法语，比 first appearance 或 launch 更简洁有力。它既可以作名词（the debut of…），也可以作动词（the product debuted last week）。适用于描述新产品发布、新领域开拓、新阶段开始。雅思写作 Task 1 描述产品生命周期时特别好用。
| 学生写法 | 升级写法 |
|---|---|
| The product was first shown last month. | The product made its debut last month. |
| This was the first time the app appeared. | This was the app’s international debut. |
| The company launched a new service. | The company debuted a new service in the Asian market. |
例句： The latest version of the smartphone made its global debut at a press conference in Shanghai.
写作建议
这4个词有个共同特点：它们都是动词（或名词化用法），而且是高频可迁移词。
- power 用在”科技/革新/驱动类”话题
- tap into 用在”资源利用/潜力开发”类话题
- broaden 用在”教育/视野/技能/渠道”类话题
- debut 用在”新产品/新阶段/首次”类话题
下次写作文前，把这4个词写在草稿纸角——写完后检查，看看你原本用的词能不能替换成它们。替换一个，语言档次就上一个台阶。
