The soil here supports a rich ecosystem, and scientists from overseas come to study this special region of the continent. It covers an area of many million square kilometres, and its exact length is hard to measure. The biodiversity of the forest is amazing: thousands of species live together, from the small nut and the famous Brazil nut to the beautiful lily and the floating water lily. The variety of wildlife is beyond imagination. Beneath the tall trees, a mass of green plants grows in the shade. The towering hardwood trees provide homes for every living thing. A rare mammal like the jaguar can survive here, while a tiny frog also plays its part. Every creature acts in turn: the insect feeds the birds, and the microorganism helps break down dead leaves into nutrients. The forest seems to breathe life into the whole world. Trees take in carbon and release oxygen, and thus the forest works like a giant machine. If we destroy it, many living things will disappear forever. Sadly, this balance is now in danger due to human activity. The growth of agriculture means that farmers raise more cattle, and the impact on the forest is serious. The threat of extinction is real, and the damage to the climate continues to build up. The rise of the global temperature turns the forest into a huge greenhouse, and the gas from burning land causes longer droughts. People must come up with new ideas, and such tasks call for the action of everyone. One useful application of science is the field guide in the brochure published by a wildlife organization. It is absolutely necessary to protect every green belt of forest. A gold medal cannot replace the true image of nature. Think of the shark and the whale; they spring to mind when we talk about ocean life. The deer and the dolphin also need safe homes. Scientists track the movement of wild animals and study each habitat closely, because these creatures have nowhere else to go. The dolphin in the river and every resident of the forest need protection. From the chief of the village to every member of the committee, everyone must share the duty. The problem is entirely ours to solve, and the smog in big cities shows how urgent it is. We need to get rid of pollution, and people have begun to protest against factories that put profit above nature. The defence of the forest requires various actions. It is a long process, but it brings both economic and environmental benefits. The new policy should be carried out by every government branch, and the strategy must be clear to all. Some cities have begun to recycle waste, and many people take the subway instead of driving. The former farmland is now growing trees again, and local officials are helping to fight poverty without harming nature. We must stop using poison in the fields, because chemicals leave a heavy consequence on the land. Every small step can give rise to great changes, and we all hope for a further improvement in the future. B. 语境串记单词（汉语译文） 雨林是我们绝不能(harm)伤害的自然宝藏。这里的(soil)土壤滋养着丰富的(ecosystem)生态系统，来自(overseas)海外的科学家前来研究这个(continent)大陆上的特殊(region)地区。它覆盖数百万(million)平方公里，确切(length)长度难以测量。森林的(biodiversity)生物多样性令人惊叹：成千上万种(species)物种生活在一起，从小小的(nut)坚果和著名的(Brazil nut)巴西坚果，到美丽的(lily)百合和漂浮的(water lily)睡莲。(wildlife)野生动植物的(variety)种类超乎想象。在高大的树下，(beneath)下面长着一(mass)大片绿色植物。(towering)高耸的(hardwood)阔叶树为每一种(living)生物提供家园。像(jaguar)美洲豹这样的珍稀(mammal)哺乳动物能在这里(survive)生存，小小的(frog)青蛙也发挥着作用。每一种生物都(in turn)依次发挥作用：(insect)昆虫喂养鸟类，(microorganism)微生物帮助把枯叶(break down)分解成(nutrient)营养素。 森林似乎给整个世界(breathe life into)注入活力。树木吸收(carbon)碳，释放(oxygen)氧气，(thus)因此森林像一台巨大的机器运转。如果我们毁掉它，许多生命将永远(disappear)消失。可悲的是，由于(due to)人类活动，这种平衡正面临危险。(agriculture)农业的发展意味着农民饲养更多(cattle)牛，对森林的(impact)影响十分严重。(extinction)灭绝的威胁真实存在，对(climate)气候的(damage)破坏持续(build up)加剧。(global)全球气温上升使森林变成巨大的(greenhouse)温室，燃烧土地产生的(gas)气体导致更长的(drought)旱灾。人们必须(come up with)想出新的办法，这样的任务(call for)要求每个人采取行动。科学的一个有用(application)应用是野生动物(organization)组织出版的(brochure)小册子里的野外指南。保护每一片绿色(belt)地带是(absolutely)绝对必要的。金牌(medal)无法取代自然的真实(image)形象。想想(shark)鲨鱼和(whale)鲸鱼；当我们谈论海洋生物时，它们首先(spring to mind)浮现脑海。(deer)鹿和海豚也需要安全的家园。 科学家(track)追踪野生动物的活动，仔细研究每一个(habitat)栖息地，因为这些生物已经(nowhere)无处可去。河里的(dolphin)海豚和森林里的每一位(resident)居民都需要保护。从村子的(chief)首领到(committee)委员会的每一位成员，人人都要分担责任。问题(entirely)完全要靠我们解决，大城市的(smog)雾霾显示了问题多么紧迫。我们需要(get rid of)摆脱污染，人们已经开始(protest)抗议那些把(profit)利润置于自然之上的工厂。对森林的(defence)防御需要(various)各种各样的行动。这是一个漫长的(process)过程，但会带来(economic)经济上和环境上的双重好处。新(policy)政策应该由每个政府(branch)部门执行，(strategy)策略必须人人清楚。一些城市已开始(recycle)回收利用垃圾，许多人改乘(subway)地铁。(former)昔日的农田重新种上了树，当地(official)官员们正在帮助消除(poverty)贫困而不伤害自然。我们不能在田里使用(poison)毒药，因为(chemical)化学制品会给土地留下沉重的(consequence)后果。每一小步都能(give rise to)带来巨大变化，我们都期待未来(further)进一步的改善。 第二部分：词形转变表 序号 原词 词形变化 1 harm v.&n.伤害 harmful (adj.) 有害的；harmless (adj.) 无害的 2 survive v.生存 survival (n.) 生存；survivor (n.) 幸存者 3 disappear v.消失 disappearance (n.) 消失；appear (v.) 出现 4 damage v.&n.损害 damaged (过去式)；damaging (adj.) 有害的 5 global adj.全球的 globally (adv.) 全球地；globe (n.) 地球 6 organize v.组织 organization (n.) 组织；organizer (n.) 组织者 7 absolutely adv.绝对地 absolute (adj.) 绝对的 8 profit n.利润 profitable (adj.) 有利可图的；profitably (adv.) 9 defend v.防御 defence (n.) 防御；defensive (adj.) 防御性的 10 various adj.各种的 variety (n.) 种类；vary (v.) 变化 11 process n.过程 v.加工 processed (过去式)；processing (n.) 加工 12 economic adj.经济的 economy (n.) 经济；economical (adj.) 节约的 13 recycle v.回收利用 recycling (n.) 回收；recyclable (adj.) 可回收的 14 poison v.污染 n.毒药 poisonous (adj.) 有毒的；poisoning (n.) 中毒 15 impact n.影响 v.有影响 impactful (adj.) 有影响的 16 mammal n.哺乳动物 mammalian (adj.) 哺乳类的 第三部分：梯度复现与多题型练习 题型1：英汉互译（30题） 乐思英语 ·语境串记单词 第 10 / 17 页 学科网（北京）股份有限公司 子题A：英译中（20个） 1. harm → __________ 2. soil → __________ 3. ecosystem → __________ 4. species → __________ 5. variety → __________ 6. wildlife → __________ 7. mammal → __________ 8. survive → __________ 9. insect → __________ 10. nutrient → __________ 11. carbon → __________ 12. oxygen → __________ 13. impact → __________ 14. extinction → __________ 15. damage → __________ 16. climate → __________ 17. global → __________ 18. gas → __________ 19. habitat → __________ 20. strategy → __________ 子题B：中译英（10个） 1. 土壤 → __________ 2. 生态系统 → __________ 3. 物种 → __________ 4. 野生动植物 → __________ 5. 生存 → __________ 6. 影响 → __________ 7. 灭绝 → __________ 8. 气候 → __________ 9. 栖息地 → __________ 10. 策略 → __________ 【答案与解析】 子题A（英译中）： 1. harm — 伤害 2. soil — 土壤 3. ecosystem — 生态系统 4. species — 物种 5. variety — 种类 6. wildlife — 野生动植物 7. mammal — 哺乳动物 8. survive — 生存 9. insect — 昆虫 10. nutrient — 营养素 11. carbon — 碳 12. oxygen — 氧气 13. impact — 影响 14. extinction — 灭绝 15. damage — 损害 16. climate — 气候 17. global — 全球的 18. gas — 气体 19. habitat — 栖息地 20. strategy — 策略 子题B（中译英）： 1. soil 2. ecosystem 3. species 4. wildlife 5. survive 6. impact 7. extinction 8. climate 9. habitat 10. strategy 题型2：词形变换（10题） 1.

The rich soil and warm weather keep a perfect ecosystem running, and its biodiversity is greater than anywhere else on the earth. Thousands of species live here, from the small nut to the famous Brazil nut, from the beautiful lily to the floating water lily. The variety of wildlife is hard to imagine. Beneath the tall trees, a mass of plants covers the ground, and the towering hardwood trees give homes to every living thing. A rare mammal like the jaguar can survive here, and a tiny frog plays its part as well. Every creature acts in turn: the insect feeds the birds, and the microorganism helps break down dead leaves into nutrients for the trees. Every part of the forest works together like a great family, and the smallest creature matters as much as the largest one. The forest seems to breathe life into the whole planet. Trees take in carbon and release oxygen, and thus they clean the air for all of us. But this balance is now in danger due to human activity. The growth of agriculture means that farmers raise more cattle, and the impact on the forest is serious. The threat of extinction is real, and the damage to the climate continues to build up. The rise of the global temperature turns the forest into a huge greenhouse, and the gas from burning land causes longer droughts. Many organizations are trying to come up with new ways to help, and such tasks call for action from everyone. A useful application of science appears in the brochure published by a wildlife organization, and it is absolutely important to protect every green belt of forest. A gold medal cannot replace the true image of nature, and the shark and the whale should also spring to mind when we think about the sea. Scientists track the movement of wild animals and study each habitat closely, because these creatures have nowhere else to go. The dolphin in the river and every resident of the forest need protection. From the chief of the village to every member of the committee, everyone must share the duty.

The new policy should be carried out by every government branch, and the strategy must be clear to all. Some cities have begun to recycle waste, and the former farmland is growing trees again. Local officials are helping to fight poverty without harming nature, and we must stop using poison in the fields, because chemicals leave a heavy consequence on the land. Every small step can give rise to great changes, and we all hope for a further improvement in the future.

The soil here supports a rich ecosystem, and scientists from overseas come to study this special region of the continent. It covers an area of many million square kilometres, and its exact length is hard to measure. The biodiversity of the forest is amazing: thousands of species live together, from the small nut and the famous Brazil nut to the beautiful lily and the floating water lily. The variety of wildlife is beyond imagination. Beneath the tall trees, a mass of green plants grows in the shade. The towering hardwood trees provide homes for every living thing. A rare mammal like the jaguar can survive here, while a tiny frog also plays its part. Every creature acts in turn: the insect feeds the birds, and the microorganism helps break down dead leaves into nutrients. The forest seems to breathe life into the whole world. Trees take in carbon and release oxygen, and thus the forest works like a giant machine. If we destroy it, many living things will disappear forever. Sadly, this balance is now in danger due to human activity. The growth of agriculture means that farmers raise more cattle, and the impact on the forest is serious. The threat of extinction is real, and the damage to the climate continues to build up. The rise of the global temperature turns the forest into a huge greenhouse, and the gas from burning land causes longer droughts. People must come up with new ideas, and such tasks call for the action of everyone. One useful application of science is the field guide in the brochure published by a wildlife organization. It is absolutely necessary to protect every green belt of forest. A gold medal cannot replace the true image of nature. Think of the shark and the whale; they spring to mind when we talk about ocean life. The deer and the dolphin also need safe homes. Scientists track the movement of wild animals and study each habitat closely, because these creatures have nowhere else to go. The dolphin in the river and every resident of the forest need protection. From the chief of the village to every member of the committee, everyone must share the duty. The problem is entirely ours to solve, and the smog in big cities shows how urgent it is. We need to get rid of pollution, and people have begun to protest against factories that put profit above nature. The defence of the forest requires various actions. It is a long process, but it brings both economic and environmental benefits. The new policy should be carried out by every government branch, and the strategy must be clear to all. Some cities have begun to recycle waste, and many people take the subway instead of driving. The former farmland is now growing trees again, and local officials are helping to fight poverty without harming nature. We must stop using poison in the fields, because chemicals leave a heavy consequence on the land. Every small step can give rise to great changes, and we all hope for a further improvement in the future. B. 语境串记单词（汉语译文） 雨林是我们绝不能(harm)伤害的自然宝藏。这里的(soil)土壤滋养着丰富的(ecosystem)生态系统，来自(overseas)海外的科学家前来研究这个(continent)大陆上的特殊(region)地区。它覆盖数百万(million)平方公里，确切(length)长度难以测量。森林的(biodiversity)生物多样性令人惊叹：成千上万种(species)物种生活在一起，从小小的(nut)坚果和著名的(Brazil nut)巴西坚果，到美丽的(lily)百合和漂浮的(water lily)睡莲。(wildlife)野生动植物的(variety)种类超乎想象。在高大的树下，(beneath)下面长着一(mass)大片绿色植物。(towering)高耸的(hardwood)阔叶树为每一种(living)生物提供家园。像(jaguar)美洲豹这样的珍稀(mammal)哺乳动物能在这里(survive)生存，小小的(frog)青蛙也发挥着作用。每一种生物都(in turn)依次发挥作用：(insect)昆虫喂养鸟类，(microorganism)微生物帮助把枯叶(break down)分解成(nutrient)营养素。 森林似乎给整个世界(breathe life into)注入活力。树木吸收(carbon)碳，释放(oxygen)氧气，(thus)因此森林像一台巨大的机器运转。如果我们毁掉它，许多生命将永远(disappear)消失。可悲的是，由于(due to)人类活动，这种平衡正面临危险。(agriculture)农业的发展意味着农民饲养更多(cattle)牛，对森林的(impact)影响十分严重。(extinction)灭绝的威胁真实存在，对(climate)气候的(damage)破坏持续(build up)加剧。(global)全球气温上升使森林变成巨大的(greenhouse)温室，燃烧土地产生的(gas)气体导致更长的(drought)旱灾。人们必须(come up with)想出新的办法，这样的任务(call for)要求每个人采取行动。科学的一个有用(application)应用是野生动物(organization)组织出版的(brochure)小册子里的野外指南。保护每一片绿色(belt)地带是(absolutely)绝对必要的。金牌(medal)无法取代自然的真实(image)形象。想想(shark)鲨鱼和(whale)鲸鱼；当我们谈论海洋生物时，它们首先(spring to mind)浮现脑海。(deer)鹿和海豚也需要安全的家园。 科学家(track)追踪野生动物的活动，仔细研究每一个(habitat)栖息地，因为这些生物已经(nowhere)无处可去。河里的(dolphin)海豚和森林里的每一位(resident)居民都需要保护。从村子的(chief)首领到(committee)委员会的每一位成员，人人都要分担责任。问题(entirely)完全要靠我们解决，大城市的(smog)雾霾显示了问题多么紧迫。我们需要(get rid of)摆脱污染，人们已经开始(protest)抗议那些把(profit)利润置于自然之上的工厂。对森林的(defence)防御需要(various)各种各样的行动。这是一个漫长的(process)过程，但会带来(economic)经济上和环境上的双重好处。新(policy)政策应该由每个政府(branch)部门执行，(strategy)策略必须人人清楚。一些城市已开始(recycle)回收利用垃圾，许多人改乘(subway)地铁。(former)昔日的农田重新种上了树，当地(official)官员们正在帮助消除(poverty)贫困而不伤害自然。我们不能在田里使用(poison)毒药，因为(chemical)化学制品会给土地留下沉重的(consequence)后果。每一小步都能(give rise to)带来巨大变化，我们都期待未来(further)进一步的改善。 第二部分：词形转变表 序号 原词 词形变化 1 harm v.&n.伤害 harmful (adj.) 有害的；harmless (adj.) 无害的 2 survive v.生存 survival (n.) 生存；survivor (n.) 幸存者 3 disappear v.消失 disappearance (n.) 消失；appear (v.) 出现 4 damage v.&n.损害 damaged (过去式)；damaging (adj.) 有害的 5 global adj.全球的 globally (adv.) 全球地；globe (n.) 地球 6 organize v.组织 organization (n.) 组织；organizer (n.) 组织者 7 absolutely adv.绝对地 absolute (adj.) 绝对的 8 profit n.利润 profitable (adj.) 有利可图的；profitably (adv.) 9 defend v.防御 defence (n.) 防御；defensive (adj.) 防御性的 10 various adj.各种的 variety (n.) 种类；vary (v.) 变化 11 process n.过程 v.加工 processed (过去式)；processing (n.) 加工 12 economic adj.经济的 economy (n.) 经济；economical (adj.) 节约的 13 recycle v.回收利用 recycling (n.) 回收；recyclable (adj.) 可回收的 14 poison v.污染 n.毒药 poisonous (adj.) 有毒的；poisoning (n.) 中毒 15 impact n.影响 v.有影响 impactful (adj.) 有影响的 16 mammal n.哺乳动物 mammalian (adj.) 哺乳类的 第三部分：梯度复现与多题型练习 题型1：英汉互译（30题） 乐思英语 ·语境串记单词 第 1 / 12 页 学科网（北京）股份有限公司 子题A：英译中（20个） 1. harm → __________ 2. soil → __________ 3. ecosystem → __________ 4. species → __________ 5. variety → __________ 6. wildlife → __________ 7. mammal → __________ 8. survive → __________ 9. insect → __________ 10. nutrient → __________ 11. carbon → __________ 12. oxygen → __________ 13. impact → __________ 14. extinction → __________ 15. damage → __________ 16. climate → __________ 17. global → __________ 18. gas → __________ 19. habitat → __________ 20. strategy → __________ 子题B：中译英（10个） 1. 土壤 → __________ 2. 生态系统 → __________ 3. 物种 → __________ 4. 野生动植物 → __________ 5. 生存 → __________ 6. 影响 → __________ 7. 灭绝 → __________ 8. 气候 → __________ 9. 栖息地 → __________ 10. 策略 → __________ 题型2：词形变换（10题） 1.

The rich soil and warm weather keep a perfect ecosystem running, and its biodiversity is greater than anywhere else on the earth.
