2025年托福写作机经汇总

第一套 整套重复上午场

　　综合写作 哺乳动物

　　主题：有袋类哺乳动物中育儿袋类与其他哺乳动物在适应能力方面的比较及原因探讨

　　阅读

　　1. marsupials 中育儿袋类(pouched)的幼崽在妈妈肚子里发育时间短(short development time

　　in the mother's womb ) ， 导 致 发 育 不 完 全(incompletely developed)。比如袋鼠幼崽出生时非常小且发育程度低，许多器官和生理机能尚未成熟，这使得它们在外界环境中的生存面临更多挑战，相比发育更完善的其他哺乳动物，适应能力较弱。

　　2. 有 袋 类 哺 乳 动 物 不 能 有 效 控 制 自 己 的 体 温( unable to control body temperature effectively)。它们缺乏像一些其他哺乳动物那样完善的体温调节机制，在 环 境 温 度 变 化 较 大 时 ，很难维持稳定的体温，这限制了它们在不同环境中的生存和活动，进一步体现出其适应能力不如其他哺乳动物。

　　3. 有袋类哺乳动物(marsupials)和其他哺乳动物都居住在澳大利亚(both live in Australia)，在与其他哺乳动物的竞争(competition)中，有袋类哺 乳 动 物 ( marsupials ) 不 能 成 功 生 存 ( not successful to survive)。例如在资源获取方面，由于有袋类哺乳动物(marsupials)在身体结构、生理特性等方面的局限，在与其他哺乳动物争夺食物、栖息地等资源时往往处于劣势，导致它们在澳大利亚的生存空间不断被挤压，反映出其适应能力较弱。

　　听力

　　1. 虽然 marsupials 幼崽在妈妈肚子里发育时间短( short development time in the mother's womb)，但出生后会在育儿袋(pouch)中继续长时间的发育和成长。在育儿袋中，幼崽能得到相对稳定的环境，妈妈可以通过育儿袋内的特殊结构和分泌物为幼崽提供适宜的温度、营养等，弥补了早期发育不完全(incompletely developed)的不足，所以不能简单认为它们适应能力弱。

　　2. 有袋类哺乳动物有独特的体温调节策略(unique body temperature regulation strategies)。例如它们可以通过行为调节体温，在炎热时寻找阴凉处，寒冷时晒太阳或者蜷缩身体等，而且其身体的代谢率也能根据环境温度进行一定程度的调整，并非完 全 不 能 控 制 自 己 的 体 温 ( unable to control body temperature effectively)，说明它们在体温调节方面具备一定的适应能力。

　　3. 在澳大利亚，有袋类哺乳动物(marsupials)和其他哺乳动物长期共同进化(co - evolve)，各自占据了不同的生态位(ecological niche)。有袋类哺乳动物(marsupials)有其独特的生存优势，比如 袋 鼠 的 强 大 跳 跃 能 力 使 其 能 够 快 速 移 动 并 获取 特 定 区域 的 食 物 资 源 ，在与其他哺乳动物的竞争(competition)中并非处于完全劣势，它们在澳大利亚生态系统中成功生存繁衍至今，证明了它们具有一定的适应能力(adaptability)，并非不能成功生存(not successful to survive)。

　　政府类 重复 2023.10.21

Your professor is teaching a class on sociology. Write a post responding to the professor’s question.

In your response, you should

　　· express and support your personal opinion

　　· make a contribution to the discussion in your own words

　　An effective response will contain at least 100 words. You have ten minutes to write.

　　Doctor Achebe: This week, we will be discussing space exploration. Some people think that it is a waste of money for governments to fund space exploration.

　　Others disagree with this view, arguing that space exploration is a valuable and necessary investment for our future. They think that it is worthy for governments to fund space exploration. l want to know what you think about this topic, Do you think that governments should fund space exploration? Why or why not?

　　Kelly: I don't think that governments should fund space exploration because it will be too costly to build spaceships and develop related technologies.

　　Though space exploration tech costs billions, it doesn't offer direct benefits to most people, which makes its funding a controversial issue

　　Paul: Personally, l do think that all the costs will be worth it. The potential scientific discoveries and technological advancements could have far-reaching impacts that justify the initial investment, imagine the new inventions that might come from this exploration. Such technology could greatly improve our everyday lives.

　　范文：

　　I contend that governments should unequivocally fund space exploration, as it serves as a catalyst for technological innovation. Space missions have historically driven breakthroughs with terrestrial applications. For example, satellite technology, initially developed for space research, now underpins GPS navigation, weather forecasting, and global communication systems—technologies indispensable to modern life. Additionally, innovations like MRI machines and water purification systems trace their origins to NASA’s research, demonstrating how space exploration addresses critical human needs. Skeptics may argue that private companies like SpaceX can lead space exploration. However, private entities often prioritize profit over pure scientific inquiry. Government-funded programs, such as the European Space Agency’s climate monitoring initiatives or India’s cost-effective Mars Orbiter Mission, focus on collective benefits rather than commercial gains. While balancing budgets for social welfare is vital, defunding space exploration would stifle progress in science, sustainability, and global collaboration. By investing in space, governments secure humanity’s capacity to thrive both on Earth and in future interplanetary endeavors.

写作第二套

　　综合写作

　　主题：提取二氧化碳的挑战

　　阅读

　　1. there is the question of whether locations proposed for storing CO2 have enough space.

　　2. if CO2 escapes from underground storage sites, it can pose risks to human health.

　　3. a wide range of costs are associated with the process of storing CO2 underground.

　　听力

　　1. Well, carbon dioxide doesn't gas under normal conditions. Gases definitely take lots of space. But if the SO 2is exposed to high pressures and the high temperatures before being stored underground, it will transform from a gas into a super critical fluid. Super critical foods are more compressed and therefore occupy less space than gases. If we process SO 2 at high pressures and

　　temperatures and then store it as a super critical fluid, it will take up less space. Which decreases the need for so much storage space.

　　2. we can minimize the health risks in SO 2 weeks based on research that has been done on them. Carbon dioxide leaking from the underground storage units usually stays close to the ground. This means that people would only get sick if they breathe the air close to the ground. For example is they were sleeping on the ground while camping. So we can take appropriate safety measures. We can install monitoring devices in areas where SO 2 is stored. When the monitoring devices detect

　　SO 2 they will sound a warning to alert people to leave the area quickly and not breathe the air close to the ground.

　　3. some of the costs can actually be offset by financial benefits. For example, some of the sites suitable for SO 2 storage are deep underground layers of rock that contain another gas called methane. When carbon that is injected into those rocks, the rocks release the methane gas. Methane is commercially valuable as fuel, and so the methane released at the storage sites can be collected and sold.

　　Profits from selling methane can at least partly make up for the high costs of carbon dioxide storage.

写作第三套

　　综合写作 日常生活 重复2024.08.24

　　主题：自来水中添加氟化物的作用

　　阅读

　　1. 增强牙齿抗蛀能力：氟化物有助于牙齿抵御蛀牙的侵袭。

　　2. 抗菌效果：氟化物具有抑制口腔细菌生长的作用。

　　3. 促进骨骼健康：适量氟化物的摄入有助于减少骨骼疾病的风险。

　　听力

　　1. 氟化物在口腔中的停留时间短暂，对于预防蛀牙的效果有限。

　　2. 氟化物可能与水管中的金属元素发生反应，生成潜在的有毒化合物，对健康构成威胁。

　　3. 长期过量摄入氟化物可能导致骨骼脆弱，增加骨折风险。

　　Doctor Achebe: We've been talking about the process of starting a new business. One of the most important aspects of the process is staffing-that is, deciding which people to hire. Please discuss the following question: ls it better for new businesses to hire experienced veterans of the industry or to staff the business with younger employees who are right out of university? Why do you think so?

　　Kelly: I think a company should staff a business with the most experienced employees possible. If you're starting a new business, you need people around you who know what they are doing and can quickly get the business up to speed. Spending time training inexperienced people will slow you down.

　　Paul: I understand what Claire is saying, but if you are starting a new business,you want people who are particularly enthusiastic and energetic. Who better than a recent graduate to bring those qualities to the job? You would be guaranteed an ambitious hard worker.

写作第四套

　　综合写作 天文学 重复2012.10.28

　　主题：金星上的灰光形成的原因

　　阅读

　　1. 太阳紫外线(ultraviolet rays of the sun)与金星大气层(the atmosphere of Venus)发生反应(reaction)，当一个氧原子(oxygen atom)分解 形 成 两 个 氧 原 子 时 会 产 生 这 种 灰 光 ( Ashen

　　Light)。这是基于化学反应(chemical reaction)的原理，推测在金星的特殊环境下，这种原子层面的变化能够释放出光线，从而形成人们观测到的灰光现象。

　　2. 可能是风暴(storm)产生的闪电(lightning)导致了灰光的出现。在 金 星 的 天 气 系 统 中 ，风暴活动可能会引发强烈的电荷放电现象，即闪电，这些闪电所发出的光在特定条件下可能被观测为灰光。

　　3. 可能是望远镜(telescope)存在缺陷(flaw)，使得观测到的所谓灰光实际上是由于望远镜本身的问题，而不是金星上真实存在的现象。也许是望远镜的光学部件出现偏差，或者是观测过程中的干扰导致了错误的视觉效果。

　　听力

　　1. 这种化学反应(chemical reaction)在理论上观 测 到 的 光 应 该 是 黄 色 ( yellow ) 或 金 色(golden)，而不是实际观测到的绿色(green)，从颜色的差异上说明这种化学反应并非是灰光形成的真正原因。

　　2. 风暴多聚集在金星的白昼一侧(day-side)，然而 观 测 到 的 灰 光 却 在 金 星 的 夜 晚 一 侧 ( night-

　　side)，位 置 不 相 符 。并且强调风暴的强度太弱(too weak)，不足以产生能够被观测到的灰光现象，从而否定了这一理论。

　　3. 很多天文学家(astronomers)在不同的地方(different places)使用不同的望远镜(different telescopes)都观测到了灰光(Ashen Light)，如果是望远镜的问题，不可能在不同的设备上都出

　　现相同的错误观测结果，所以这种现象并非是由望远镜的缺陷引起的。
