一、背景速览

「脑腐」这顶帽子，短视频戴了好几年，可像样的研究少得可怜。Hana Kiros 在《大西洋月刊》梳理现有文献：证据方向不妙，分量撑不住结论，这个缺口反倒成了科技公司的挡箭牌。她以一个被误读的脑成像研究为例，说清了“不知道”会怎样同时喂饱恐慌和草率的政策。

二、英文节选

Among the many aspects of online life accused of rotting our brains, a certain folk psychology holds that short-form video is an especially egregious driver of the decay. In an interview last month promoting his new film, in which a London couple move their tech-dependent kids to a barn without electricity, Andrew Garfield described himself as addicted to an Instagram feed full of “weird ceramics” and Japanese craftspeople. “I’ve given all of those hours to nothing,” he told Variety. “It’s genuinely enraging because we don’t have as much control over these impulses as we should.” Even Steve Chen, one of the co-founders of YouTube—home to many a recycled TikTok on its Shorts—has said that he’s wary of his kids watching too much short-form video, because of the damage it does to attention. Sometimes, when I emerge from the dark vortex of a scroll gone too long, I worry that my thoughts will permanently become as flighty as my feed.

三、中文译文

在种种被指为腐蚀大脑的网络生活里，有一种民间心理认定，短视频是这场衰退格外恶劣的推手。上个月，安德鲁·加菲尔德（Andrew Garfield）为新片宣传时接受采访，那部片子讲的是一对伦敦夫妇带着离不开电子设备的孩子搬进一间没通电的谷仓。他说自己沉迷于一个塞满“怪陶器”和日本手工艺人的 Instagram 信息流。“那些小时我全给了虚无，”他告诉《综艺》（Variety）。“这着实让人恼火，因为对这些冲动，我们并没有本该有的那种控制力。”就连 YouTube 联合创始人之一史蒂夫·陈（Steve Chen）也说过，他对自己孩子看太多短视频感到担心，因为那会损害注意力；YouTube 的 Shorts 上搬运来的 TikTok 内容向来不少。有时候，从一场刷过得久的黑暗漩涡里冒出头来，我会担心自己的思绪会就此永远像我的信息流一样飘忽不定。

五、长难句速拆

原句：This lack of data gives cover to tech executives, who, when faced with the potentially harmful effects of their products, can cite the difficulty of establishing any one app or feature as the cause of a person’s unraveling.

主干是 This lack of data gives cover to tech executives，数据缺失给高管当了掩护。who 从句说明掩护怎么起作用：can cite the difficulty of...，也就是拿“证明不了”当理由。从句里还塞着 when faced with the potentially harmful effects of their products，省略了 they are，指“面对自家产品可能的伤害时”。最容易断错的是 establish A as B：establishing 后面那一长串都是“确立”的内容，A 是 any one app or feature，B 是 the cause of a person’s unraveling；找不准这条分界，整句就会翻糊。

六、考场应用

考研英语·阅读理解：第 1 段是“例证 + 转折”结构：两个名人例子铺完，But here’s the tricky part 才落地。常考“引用名人的作用”与“作者态度”，态度落在转折之后：作者在意的是证据不足，凡说“作者认定短视频伤脑”的选项可排除。

考研英语·翻译与写作：本篇最值钱的是姿态而非词。gives cover to、the difficulty of establishing...as... 都把话说得留有余地，配合 appears to be associated with、take sth with a grain of salt，写科技话题能收住断言。示范：Claims about X are usually bolder than the evidence behind them.

雅思写作·Task 2：政府该不该管社交媒体这类题用得上。论证链：研究稀缺 → 行业握着独家数据不公开 → 政府只能在信息不足时推一刀切禁令。例证要成对给：2024 年那份脱敏潦草的起诉书，加上 TikTok“文件过时、引文被断章取义”的回应，只引一方容易被判失衡。 再看这句：

Prominent social-media accounts, including one for the prediction market Polymarket, promoted the study as more proof that TikTok is making us smooth-brained.

这句你打算怎么翻？including 那截插在哪里，先想清楚再动笔。
