英语新闻×科技阅读,一人一个难度 这一周,全世界发生了什么?25 位数学最高奖得主联名给 AI 公司写了封公开信;硅谷风投花 3500 万美元办了一所不发文凭的学校;还有你每天都在敲的键盘,字母为什么排得这么乱? 这些正在发生的事,都能用英语读懂。同一篇文章,四个难度,每个人都有自己的级别:孩子读孩子的,大人读大人的。 【两条主线:真新闻 + 真科技】 每周 5 篇精选,两条主线贯穿:一条是全球热点新闻,一条是 AI 与前沿科技,再配上生活科学、历史文化的跨学科阅读。为什么调休要补班?AI 为什么让数学家紧张?课本里的英语是标本,新闻和科技里的英语是活的。让“想知道答案”成为阅读的动力。 【一人一个级别,i+1 科学分级】 Aha 1 到 Aha 4,从剑桥少儿一路对标到真实外刊。先测一测(结合蓝思 Lexile 体系),找到属于自己的起点。我们只信一个科学原则,叫 i+1:内容永远比你现在的水平(i)高一点点(+1),踮踮脚,够得着。太简单会无聊,太难会放弃,刚刚好才最好。 【孩子读,是最好的英语启蒙】 用真正好奇的话题开启阅读,配磨耳朵音频、核心好词、开口跟读、三关挑战。学过的词两周后会在新文章里和你“偶遇”,科学复现,不靠死记。 【大人读,是给自己的每日充电】 不用啃原版外刊也能跟上世界:AI、财经、科学、健康,用适合自己的难度,每天十分钟读一篇正在发生的新闻。想重拾英语的你,从今天这篇开始,而不是从十年前的课本开始。 【全家读,是每周更新的共同话题】 孩子读 Aha 1,你读 Aha 4,聊的是同一件事。别人家的亲子话题靠憋,你们家的谈资每周一更新。 【专业的人,做专业的内容】 内容团队由前路透社记者、TESOL 国际英语教育专家与科学家、AI 领域专业作者组成。每篇选题、每个数字、每道题,都按新闻编辑室的标准把关。 一个人读,是给自己的成长;一家人读,是共同的世界。 Beyond English. Across Subjects. Into the World. Aha Time 啊哈时间,我们每周见。 What happened in the world this week? Twenty-five winners of maths' highest prize wrote an open letter to AI companies. A Silicon Valley VC spent $35 million on a school that grants no degrees. And the keyboard you type on every day: why are the letters in that strange order? Now you can read it all in English, at your own level. One story, four levels of difficulty. Kids read theirs; adults read theirs; everyone talks about the same thing. TWO TRACKS: REAL NEWS, REAL TECH Five hand-picked reads every week on two main tracks: global news, and AI & frontier tech, plus everyday science and culture across disciplines. Why do make-up workdays exist? Why does AI make mathematicians nervous? Textbook English is a specimen; the English of news and technology is alive. ONE LEVEL FOR EVERYONE, POWERED BY i+1 From Cambridge Young Learners all the way to authentic news English (Aha 1-4). Take a quick placement test (aligned with Lexile) and find your starting point. We follow one principle: input should sit just one step above your level. Too easy is boring, too hard is crushing; just right is addictive. FOR KIDS: READING THAT STARTS WITH “I WANT TO KNOW” Audio warm-ups, key words, read-aloud practice, and three-round challenges. Words you learn quietly reappear in new stories two weeks later. Science, not rote. FOR ADULTS: TEN MINUTES A DAY WITH THE REAL WORLD AI, business, science, health, at a level that fits you. Restart your English from today's news, not from a ten-year-old textbook. FOR FAMILIES: A NEW SHARED TOPIC EVERY WEEK Your kid reads Aha 1, you read Aha 4, and dinner-table conversation writes itself. CURATED BY PROFESSIONALS Our editorial team brings together a former Reuters journalist, TESOL-qualified English educators, and specialist writers in science and AI. Every story, every number, every question is checked to newsroom standards. Read alone, and grow. Read together, and share a world. Beyond English. Across Subjects. Into the World. Aha Time. See you every week. 服务条款(Terms of Use):https://cacademy.ai/agreement/user 隐私政策(Privacy Policy):https://cacademy.ai/agreement/privacy
