一、背景速览
牛肉一直被视为理所当然的日常食物，如今却突然成了明星：美国卫生主管官员把它放上了新版倒置食物金字塔的顶端。但《纽约客》判断，眼下很可能就是牛肉的最高点。几股力量正凑到一起：干旱让美国牛群缩到 1951 年以来最少，柴油、化肥与饲料价格齐涨，而牛在气候账上代价极高，六七磅玉米才换一磅肉，反刍还排甲烷。作者拿内燃机打比方：燃油车正被电动车取代，牛肉也可能走到同样的转折点。
二、英文节选
Yet, despite that ringing endorsement, there seems at least a chance that this moment might also be the high-water mark for cut-up cattle. In the same way that, around the world, internal-combustion cars are suddenly, and rapidly, giving way to electric vehicles, it's possible that a combination of technological, economic, ecological, and cultural factors might be lining up to challenge the hold of beef. If so, it would be a big deal: beef cattle use something like sixty per cent of the planet's agricultural land, even while they provide just two per cent of its calories.
As of January, the country's total cattle herd was smaller than it had been since 1951, three years before the birth of Burger King. Even if the El Niño now developing were to drench the Southwest, it will be years before the herd rebuilds: a cow takes nine months to gestate a calf, and then it's seventeen months before that calf is large enough to slaughter for beef.
Since March, following the start of the war on Iran, global E.V. sales have surged thirty-five per cent; some analysts are suggesting they'll be outselling conventional cars by 2030. Just because something's been normal for a very long time doesn't mean it's a lock to stay that way.
三、中文译文
然而，尽管得到了这份响亮的背书，此刻也未尝不可能是分割牛肉的最高水位。就像在世界各地，燃油车正突然而迅速地让位于电动车一样，技术、经济、生态与文化这几股力量，也可能正凑到一处，去挑战牛肉的地位。如果真是这样，那就是件大事：肉牛占用了这颗星球约六成的农业用地，提供的热量却只有百分之二。
截至今年 1 月，美国牛群总数是 1951 年以来的最低水平，而那一年距离汉堡王创立还有三年。就算眼下正在形成的厄尔尼诺把西南部浇个透，牛群也要好几年才能恢复：母牛怀胎要九个月，之后还得再过十七个月，小牛才够重、能出栏宰杀。
自 3 月伊朗战争爆发以来，全球电动车销量猛增了 35%；有分析师提出，到 2030 年它们的销量将超过燃油车。一件事正常了很久，并不意味着它就板上钉钉会一直这样下去。
四、高频词短语
【give way to】 /ɡɪv weɪ/ v. 让位于，被……取代
例句：In many cities, petrol cars are giving way to electric ones.
译：在很多城市，燃油车正在让位于电动车。
【stark】 /stɑːk/ a. 鲜明的，触目惊心的
例句：The contrast is stark: beef uses most of the farmland but supplies few calories.
译：反差触目惊心：牛肉占用了大部分农田，却只提供很少的热量。
【parity】 /ˈpærəti/ n. 持平，相当
例句：Cultivated meat has not yet reached cost parity with beef.
译：培养肉的成本还没有和牛肉持平。
【high-water mark】 /ˈwɔːtə/ n. 最高水位；顶点，巅峰
例句：That moment may prove the high-water mark for beef consumption.
译：那一刻也许会成为牛肉消费的顶点。
【belch】 /beltʃ/ v. 喷出，排出（气体）
例句：Cattle belch methane, a gas far more heat-trapping than carbon dioxide.
译：牛会打嗝排出甲烷，这种气体的保温能力远超二氧化碳。
五、长难句速拆
原句：Even if the El Niño now developing were to drench the Southwest, it will be years before the herd rebuilds: a cow takes nine months to gestate a calf, and then it's seventeen months before that calf is large enough to slaughter for beef.
前半句是让步，Even if 引出的是「就算……也……」的假设。从句用的是 were to drench，这是虚拟语气，表示「万一真的下透了」，而不是已经发生的事。主句是 it will be + 时间 + before… 这个固定搭配，意思是「要过好几年才会」。冒号后面给这个时间打了底：母牛怀胎九个月，再加十七个月才够出栏。最容易翻错的是 before，它不表示时间先后，而是「还要多久才」。
六、考场应用
考研阅读·类比题：全文用燃油车被电动车取代，来推演牛肉可能被替代品取代，第二段的 In the same way that… 就是类比的入口。考研阅读爱问「作者为什么提到汽车」，答案要落在「说明再稳固的日常也可能迅速翻篇」，而不是去讨论车。看到 just as、in the same way 这类信号，先找被比的那一对东西。
雅思写作·Task 2：环境类题目问个人饮食选择能否影响气候，本文的数字可以直接摆成一排：肉牛占用全球约六成农业用地、只提供 2% 的热量，一磅牛肉的排放最高可达一百磅二氧化碳当量，吃八晚猪肉的破坏还不及一顿牛排。与其笼统写 beef is harmful，不如让数字自己说话。
雅思阅读·观点收束：文章先铺「牛肉正当红」的表象，再翻盘说这可能是顶点，末句用 Just because something's been normal for a very long time doesn't mean it's a lock to stay that way 收束。这种格言式结尾是主旨题的常见落点，读长文时把最后一段单独拎出来看，往往就能抓住作者真正的态度。
试译：You can eat pork eight nights a week and do less damage to the environment than you would with one steak dinner.
这句你打算怎么翻？提示：比较的两头不是「两种肉」而是「两顿饭的安排」，would 后面省了动词，先把它补回来再动笔。
