标题 Walking Faster May Help Reverse Frailty, Study Finds 中文总结 觉得运动太晚了吗？一项发表在《PLOS ONE》的新临床试验给出了不一样的答案：走快一点，而不只是走得多，能帮助老年人对抗衰弱。研究者在14个退休社区让165位平均79岁的老人参加为期4个月、每周3次的步行计划：一半人随意慢走，另一半被要求在安全前提下尽量走快。结果快走组近70%的人在至少一项衰弱指标上有改善，慢走组只有46%；快走组在6分钟步行测试中也走得更远。衰弱影响多达一半的老年人，会提高跌倒和住院风险。结论很简单：加快脚步，快走可能是健康 aging 最好的药之一。 英语知识点 1. frailty (n.) 衰弱（老年医学常用词，指体弱、易受伤的状态） - *Frailty affects up to half of older adults.* - 衰弱影响着多达一半的老年人。 2. clinical trial (n.) 临床试验 - *A new clinical trial says walking faster can help older adults fight frailty.* - 一项新的临床试验表明，走快一点可以帮助老年人对抗衰弱。 3. pick up the pace (phr.) 加快速度、加快脚步 - *The message is simple: pick up the pace.* - 结论很简单：加快脚步。 4. as fast as they safely could (phr.) 在安全的前提下尽可能快 - *The other half were told to walk as fast as they safely could.* - 另一半人被要求在安全前提下尽可能快地走。 5. compared with (phr.) 与……相比 - *Nearly seventy percent of the fast walkers improved, compared with only forty-six percent of the casual group.* - 快走组近70%的人有改善，相比之下慢走组只有46%。 6. raise the risk of (phr.) 提高……的风险 - *Frailty raises the risk of falls and hospital stays.* - 衰弱会提高跌倒和住院的风险。 7. healthy aging (n.) 健康老龄化 - *A brisk daily walk may be one of the best medicines for healthy aging.* - 每天快走可能是健康老龄化最好的药之一。 全文参考 Here is a health story that proves it is never too late to start moving. A new clinical trial says walking faster, not just walking longer, can help older adults fight frailty. Scientists studied one hundred sixty-five older adults, with an average age of seventy-nine, in fourteen retirement communities. Everyone joined a four-month walking program, three times a week. Half walked at a relaxed, casual pace. The other half were told to walk as fast as they safely could. The results were clear. Nearly seventy percent of the fast walkers improved in at least one measure of frailty, compared with only forty-six percent of the casual group. They also walked farther in a six-minute fitness test. Frailty affects up to half of older adults and raises the risk of falls and hospital stays. The message is simple: pick up the pace. A brisk daily walk may be one of the best medicines for healthy aging. 双源验证 - TIME（2026-09-30）: "Walking Faster May Help Reverse Frailty" — PLOS ONE 新试验，14 retirement homes，快走组近70%至少一项衰弱类别改善 vs 慢走组46%（Danilovich 语录） - PLOS ONE 论文/官方新闻稿（Mirage.News 转载）：整群随机对照试验，165名参与者（12-14个社区），NIH资助；配套二次分析（102人）显示快走组步频100步/分 vs 慢走组77步/分，6分钟步行测试改善率65% vs 39%

【中文总结】 无糖饮料到底能不能喝？英国利物浦大学的科学家完成了迄今规模最大、时间最长的相关随机对照试验。研究招募了493名超重或肥胖的成年人，所有人都参加减重项目，一半人每天喝水，另一半人每天喝无糖饮料。两年后，两组减重效果几乎一样：无糖饮料组平均减了4.8公斤，喝水组减了3.7公斤，差异小到没有统计意义。两组的血压、胆固醇和体成分都有改善。研究者表示，"甜味剂扰乱食欲、危害健康"的担忧在这项严格的长期试验中并未得到支持。想戒糖又舍不得快乐水？换无糖版本，效果可能和喝水一样好。这项研究发表在《英国营养学杂志》上。 【英语知识点】 1. **as well as**（和……一样好） - 例句：This new phone works as well as the old one. - 翻译：这部新手机和旧的一样好用。 2. **weight loss**（减重、减肥） - 例句：Regular exercise is the key to healthy weight loss. - 翻译：规律运动是健康减肥的关键。 3. **calorie**（卡路里） - 例句：Diet drinks contain almost no calories. - 翻译：无糖饮料几乎不含卡路里。 4. **too small to be meaningful**（太小而没有意义） - 例句：The gap between the two teams was too small to be meaningful. - 翻译：两队的差距小得不具意义。 5. **blood pressure**（血压） - 例句：Walking every day can lower your blood pressure. - 翻译：每天散步可以降低你的血压。 6. **cholesterol**（胆固醇） - 例句：Oatmeal may help reduce bad cholesterol. - 翻译：燕麦可能有助于降低坏胆固醇。 7. **swap A for B**（用B替换A） - 例句：Try to swap chips for fruit at lunch. - 翻译：午餐试着用水果代替薯片。 ## 全文参考 Here is some good news for anyone who loves diet soda. A major new study says diet drinks work just as well as water for losing weight. Researchers at the University of Liverpool in the U.K. ran the longest study of its kind. They followed four hundred ninety-three adults for two years. Everyone joined a weight-loss program. Half drank water every day. The other half drank diet drinks with no-calorie sweeteners. After two years, both groups lost about the same amount of weight. The diet drink group lost four point eight kilograms, and the water group lost three point seven. The difference was too small to be meaningful. Both groups also saw better blood pressure and cholesterol. The researchers say the fear that sweeteners harm your health is not supported by this trial. So if you are trying to cut sugar, swapping soda for a diet version may be just as good as water. 本音频为 AI 生成，新闻读两遍：第一遍正常语速，第二遍加深印象，适合跟读练听力。

练乐器的孩子更聪明？美国东北大学的新研究给这个老话题添了新证据。科学家研究了76名7到9岁的儿童，其中一半每周练琴至少30分钟。结果发现，学音乐的孩子在词汇、数学和工作记忆测试中表现更好。脑部扫描还显示，这些孩子大脑中连接"听"和"说"区域的神经纤维排列更有序——简单说，他们脑内听觉与语言之间的"高速公路"修得更结实。研究者提醒这是相关性研究，还不能证明因果关系，但令人惊讶的是，孩子们并不需要苦练多年就能看到这种关联。家里有琴童的家长，下次孩子练琴时，不妨想想：那些看似吵闹的练习，可能正在悄悄塑造一个更好的大脑。本期新闻读两遍，第一遍正常语速，第二遍加深印象，适合跟读练听力。 英语知识点 1. practice an instrument（练习乐器） 例句：She practices an instrument for thirty minutes every day. 翻译：她每天练乐器三十分钟。 2. working memory（工作记忆） 例句：Working memory helps you hold information while you use it. 翻译：工作记忆帮助你在使用信息的同时记住它。 3. score higher on tests（在考试中得更高分） 例句：Students who read daily often score higher on tests. 翻译：每天阅读的学生考试往往得更高的分数。 4. in simple terms（简单来说） 例句：In simple terms, exercise makes your heart stronger. 翻译：简单来说，运动让你的心脏更强壮。 5. the link is striking（这种关联非常显著） 例句：The link between sleep and grades is striking. 翻译：睡眠和成绩之间的关联非常显著。 6. prove（证明） 例句：One study cannot prove that music makes you smarter. 翻译：一项研究无法证明音乐能让你更聪明。 7. build a better brain（塑造更好的大脑） 例句：Reading every night may help build a better brain. 翻译：每晚阅读可能有助于塑造更好的大脑。 ## 全文参考 Here's a story for every parent: new research says learning music may help children's brains grow stronger. Scientists at Northeastern University in Boston studied seventy-six children aged seven to nine. Half of them practiced an instrument, like the piano or violin, for at least thirty minutes a week. The other half did not. The young musicians scored higher on tests of vocabulary, math, and working memory. Brain scans also showed a difference. In children who played music, the fibers connecting sound and speech areas of the brain looked better organized. In simple terms, their brains built stronger roads between hearing and speaking. The researchers say they cannot yet prove music lessons caused the gains, but the link is striking. And the children did not need years of practice to show benefits. So the next time your child practices the piano, remember: those noisy sessions might be building a better brain.

NASA的小行星样本研究有了新结论。瑞士团队分析了OSIRIS-REx探测器2023年带回的贝努（Bennu）小行星样本（约120克），发现这颗小行星并非如以往认为的形成于寒冷的外太阳系，而是诞生在"雪线"附近——水蒸气凝结成冰的特殊边界地带。在那里，内太阳系的炽热物质与外部的冰冷物质混合，冰像胶水一样把微细尘埃粘成岩石，木星则挡住粗颗粒、只放行细尘。这项9月23日发表于《Science Advances》的研究认为，贝努可能是地球等行星原始"建筑材料"的最佳标本。（双源：Space.com + ETH Zurich/phys.org） 本期新闻读两遍，第一遍正常语速，第二遍加深印象，适合跟读练听力。 ## 英语知识点 1. **asteroid** (n.) 小行星 -例句：An asteroid named Bennu orbits the sun every 1.2 years.（一颗名叫贝努的小行星每1.2年绕太阳一圈。） 2. **sample** (n./v.) 样本；取样 -例句：The spacecraft brought samples of the asteroid back to Earth.（航天器把小行星样本带回了地球。） 3. **form** (v.) 形成 -例句：Scientists used to believe Bennu formed in the cold outer solar system.（科学家过去认为贝努形成于寒冷的外太阳系。） 4. **freeze into** (phr.) 冻结成 -例句：Water vapor freezes into ice near the snow line.（在雪线附近，水蒸气冻结成冰。） 5. **act like glue** (phr.) 像胶水一样起作用 -例句：Ice acted like glue, sticking dust particles together.（冰像胶水一样把尘埃颗粒粘在一起。） 6. **play a key role** (phr.) 起关键作用 -例句：Jupiter played a key role in Bennu's birth.（木星在贝努的诞生中起了关键作用。） 7. **the ingredients that built...** (phr.) 构建……的原料/要素 -例句：Bennu may show us the original ingredients that built Earth.（贝努可能向我们展示了构建地球的原始原料。） ## 全文参考 Good morning, and welcome to Daily English News. Today is Monday, September twenty-eighth. Here is a story about a space rock that may explain how Earth was born. NASA's OSIRIS-REx spacecraft visited an asteroid named Bennu, and in twenty twenty-three it brought pieces of it home, about one hundred twenty grams. A team in Switzerland has now finished studying those samples, and the results are surprising. Scientists used to believe Bennu formed far away in the cold outer solar system. Instead, the new analysis shows it was born near a special boundary called the snow line, where water vapor freezes into ice. There, material from the hot inner solar system and the icy outer regions mixed together, and ice acted like glue, sticking tiny dust particles into bigger rocks. Giant Jupiter played a key role too, blocking coarse material while fine dust flowed around it. Bennu may be our best look at the original ingredients that built Earth.
