📖 原文/对话（来源：科技社会新闻 · 培育肉 Cultivated Meat）

Cultivated meat, also called lab-grown or cell-based meat, is no longer a science experiment confined to a petri dish. In 2020, Singapore became the first country to approve it for sale; in 2023, the United States followed with regulated clearance for cultivated chicken. The idea is deceptively simple: instead of raising and slaughtering billions of animals, scientists take a small sample of animal cells, feed them the nutrients they would naturally receive inside a body, and let them multiply in large steel tanks called bioreactors. The result looks, cooks, and tastes like conventional meat — without the farm, the slaughterhouse, or the manure.

Why does this matter? Animal agriculture is responsible for roughly fourteen percent of global greenhouse-gas emissions, consumes vast amounts of land and water, and is a leading cause of deforestation and biodiversity loss. Proponents argue that cultivated meat could slash emissions, spare animals from industrial confinement, and reduce the risk of zoonotic diseases jumping from animals to humans. For a planet expected to feed nearly ten billion people by 2050, it offers a tantalizing alternative to the status quo.

Yet the road ahead is bumpy. The biggest hurdle is cost: the first cultivated beef burger, unveiled in 2013, cost over three hundred thousand dollars to produce. Although prices have fallen dramatically, a scalable, affordable product remains years away. Critics also question whether energy-hungry bioreactors are truly greener than efficient pasture, and whether consumers will ever embrace “meat without slaughter.” Regulators, traditional farmers, and food giants are watching closely. Whether cultivated meat becomes a supermarket staple or a costly curiosity may well define the future of dinner — and the health of the planet.

• bioreactor /ˈbaɪoʊriˌæktər/ n. 生物反应器（培养罐） — Cells multiply rapidly inside large steel bioreactors.
• slaughterhouse /ˈslɔːtərhaʊs/ n. 屠宰场 — Traditional meat production still depends on the slaughterhouse.
• deforestation /ˌdiːfɔːrɪˈsteɪʃən/ n. 森林砍伐 — Livestock farming is a major driver of deforestation.

💬 跟读练习建议

1. 逐句精听跟读（shadowing）：先听 PBS Terra 视频 0:00–1:30 段落，每句暂停，模仿语音语调与节奏；重点模仿 “The idea is deceptively simple” 的轻快停顿。
2. 角色朗读（reader & skeptic）：A 读支持方（proponents 段落），B 读质疑方（critics / hurdle 段落），互换一次，体会两种立场的语气强弱对比。
3. 难点句拆分跟读：把 “scientists take a small sample of animal cells, feed them the nutrients they would naturally receive inside a body, and let them multiply…” 按逗号切三刀，分别读顺后再连成一句长句。
4. 加速挑战：原速跟读 2 遍后，提速 1.2 倍再读 1 遍，保持元音饱满、不吞尾音。

🔄 即兴口语练习

1. Do you think cultivated meat will replace traditional meat in your lifetime? Why or why not?
   • 参考要点：可从成本（cost / hurdle）、消费者接受度（consumer acceptance）、环保动机（emissions / deforestation）三角度展开；用 “I believe… / The main obstacle is…” 组织。
2. Would you be willing to try lab-grown meat? What would convince you?
   • 参考要点：谈安全（safety / regulation）、口味（taste）、伦理（animal welfare）；用条件句 “If it were cheaper and clearly labelled, I would…”。
3. Who should pay for making this technology affordable — governments, companies, or consumers?
   • 参考要点：政府补贴（subsidy）、企业研发（R&D）、市场选择（market）；用 “In my view, a mix of… is the fairest approach.”

📋 发音技巧提示

1. 弱读与 schwa /ə/：cultivated 重音在首音节 CUL-ti-və-tɪd，后三音节多为轻弱的 /ə/；bioreactor 重音在 re-ac-tor，注意 /aɪ/ 双元音不要读成单元音。
2. 连读（linking）：slaughter billions of animals 中 “billions of” 的 /z/ 与 /əv/ 自然连读；instead of raising 中 “of” 弱读成 /əv/ 并与前后词黏连。
3. 失去爆破（incomplete plosion）：looks, cooks, and tastes 三个以 /s/ 收尾的词并列，/k/ 在 looks 与 cooks 后做短暂憋气不送气，再快速接下一个词，避免每个词都重重炸开。

🗣 今日金句

“The question is not whether we can grow meat in a lab, but whether we can feed the world without destroying it.” （问题不在于我们能否在实验室里种出肉，而在于我们能否在不摧毁地球的前提下喂饱世界。）
