今天的英语材料来自 Reuters、TechCrunch 和 The Verge 的科技新闻：Intel 的强劲预期把美国芯片股推上纪录高位，AI 芯片创业公司 Cerebras 再次递交 IPO 文件，Google Gemini for Home 恢复免费连续对话，Meta 还在押注太空太阳能给 AI 基础设施供电。

我们挑 8 个没有和生词本重复、且很适合读科技财经新闻的表达。它们共同描述的是同一个现实：AI 热潮不只发生在模型里，也发生在芯片、数据中心、能源、电力和资本市场里。

1. all-time high /ˌɔːl taɪm ˈhaɪ/ n. phr.（历史最高点；纪录高位）

新闻原文：

Reuters reported that the Philadelphia SE Semiconductor Index rose to an all-time high /ˌɔːl taɪm ˈhaɪ/（历史最高点） after Intel’s strong outlook /ˈaʊtlʊk/（前景预期） revived confidence in AI-related chip demand. The index was also on track /ɑːn træk/（有望；按计划） for a record 18th single-day gain. Intel surged /sɜːrdʒd/（飙升） after signaling robust /roʊˈbʌst/（强劲的） demand for CPUs used in AI systems.

怎么用：
all-time high 是财经新闻高频词，股票、指数、销量、温度纪录都能用。它比 record high 更口语、更有“冲顶”感。

💡 实用造句： Nvidia shares hit an all-time high after the company raised its revenue forecast.

2. turbocharge /ˈtɜːrboʊtʃɑːrdʒ/ v.（给……强力提速；推动暴涨）

新闻原文：

Reuters said Intel helped turbocharge /ˈtɜːrboʊtʃɑːrdʒ/（强力推动） the AI rally /ˈræli/（上涨行情） across U.S. chipmakers. AMD and Arm also jumped, while Nvidia edged higher as investors looked for signs that AI infrastructure spending remained durable /ˈdʊrəbəl/（持久的）. In market writing, one company’s upbeat forecast can quickly become fuel for an entire sector.

怎么用：
turbocharge 原本像“装上涡轮增压”，新闻里常表示“显著加速、强力推动”，比 boost 更有画面感。

💡 实用造句： A major cloud deal could turbocharge the startup’s expansion in Asia.

3. build-out race /ˈbɪld aʊt reɪs/ n. phr.（建设竞赛；扩建竞赛）

新闻原文：

“The AI build-out race /ˈbɪld aʊt reɪs/（建设竞赛） is still on,” Reuters quoted a market strategist /ˈstrætədʒɪst/（策略师） as saying. He said semiconductor /ˌsemikənˈdʌktər/（半导体） results showed no sign that demand for AI was slowing down. The phrase points to companies racing to build data centers, buy chips, and secure power before rivals do.

怎么用：
build-out 指基础设施、网络、产能等“扩建/铺开”；race 强调各家公司都怕慢一步。

💡 实用造句： The AI build-out race is forcing utilities to rethink how quickly they can add power capacity.

4. look past /lʊk pæst/ phr.（不再纠结；越过……看更大趋势）

新闻原文：

Reuters noted that investors seemed to look past /lʊk pæst/（越过；不再纠结） DeepSeek’s latest model preview /ˈpriːvjuː/（预览版）. Last year, a low-cost Chinese AI model rattled /ˈrætəld/（震动；扰乱） Wall Street by raising doubts about expensive AI infrastructure. This time, traders focused more on earnings, valuations /ˌvæljuˈeɪʃənz/（估值）, and demand.

怎么用：
look past X 不是“看穿”，而是“暂时不把 X 当成核心问题”。财经新闻常写投资者 look past concerns。

💡 实用造句： Investors looked past the short outage and focused on the platform’s user growth.

5. file to go public /faɪl tə ɡoʊ ˈpʌblɪk/ phr.（提交上市申请）

新闻原文：

TechCrunch reported that Cerebras Systems, an AI chip startup, filed to go public /faɪld tə ɡoʊ ˈpʌblɪk/（提交上市申请） again. The company says it builds some of the fastest hardware /ˈhɑːrdwer/（硬件） for AI training and inference /ˈɪnfərəns/（推理运行）. Its earlier IPO attempt was delayed by a federal review /ˈfedərəl rɪˈvjuː/（联邦审查） and later withdrawn /wɪðˈdrɔːn/（撤回）.

怎么用：
go public = 公司上市；file to go public 强调“递交文件、迈出上市流程第一步”。

💡 实用造句： The battery startup filed to go public after signing contracts with two automakers.

6. fast inference business /fæst ˈɪnfərəns ˈbɪznəs/ n. phr.（高速 AI 推理业务）

新闻原文：

TechCrunch quoted Cerebras CEO Andrew Feldman as saying that Nvidia “didn’t want to lose the fast inference business /fæst ˈɪnfərəns ˈbɪznəs/（高速推理业务） at OpenAI,” and that Cerebras took that business from them. The article also mentioned high-profile /ˌhaɪ ˈproʊfaɪl/（高调的；备受关注的） deals with Amazon Web Services and OpenAI. In AI, inference is where a trained model actually answers users.

怎么用：
inference 已在生词本里出现过，所以今天记整个行业表达 fast inference business：它指“让模型又快又便宜地响应用户”的商业机会。

💡 实用造句： Cloud providers are competing for the fast inference business as chatbots become everyday tools.

7. behind a paywall /bɪˈhaɪnd ə ˈpeɪwɔːl/ phr.（放在付费墙后；需要付费才能用）

新闻原文：

The Verge wrote that when Google launched Gemini for Home, it put Continued Conversation behind a paywall /bɪˈhaɪnd ə ˈpeɪwɔːl/（放在付费墙后）. Starting today, Early Access /ˈɜːrli ˈækses/（抢先体验） users can once again ask follow-up /ˈfɑːloʊ ʌp/（后续的） questions without saying “Hey Google” every time and without paying. The feature now works in all supported languages and regions.

怎么用：
paywall 是“付费墙”；behind a paywall 常用于媒体、App、AI 功能：看得见，但要付费才进得去。

💡 实用造句： The company moved its best AI editing tools behind a paywall last year.

8. beam energy /biːm ˈenərdʒi/ v. phr.（传输能量；以光束形式输送能源）

新闻原文：

The Verge said Meta’s space-solar partner plans to demo /ˈdemoʊ/（演示） beaming energy /ˈbiːmɪŋ ˈenərdʒi/（传输能量） wirelessly from space to a solar farm on Earth in 2028. The satellites /ˈsætəlaɪts/（卫星） would sit in geosynchronous orbit /ˌdʒiːoʊˈsɪŋkrənəs ˈɔːrbɪt/（地球同步轨道） and collect sunlight around the clock. The goal is to strengthen the grid /ɡrɪd/（电网） for energy-hungry AI infrastructure.

怎么用：
beam 作动词时是“以光束/无线方式发送”。科幻感很强，但在太空太阳能、电信、雷达新闻里很实用。

💡 实用造句： Engineers hope the satellite can beam energy to remote areas during emergencies.
