Even after flying to places 19 are hundreds of kilometers away, they can always return to their home quickly. Scientists have studied this ability for years, and they finally found out that bees can use the sun to navigate (导航) 20 (correct). Using the position of the sun, they can tell exactly which 21 (direct) they need to fly. But on cloudy days, when the sun is hidden, bees can still find their way 22 using special parts of their eyes. These special eyes allow bees to see ultraviolet light (紫外线), which humans cannot see. This special ability is very 23 (use) for bees, because it helps them find flowers to get nectar (花蜜) even 24 bad weather days. Scientists also found that bees can remember different 25 (place) and tell the time of day based on the sun’s position. They even can tell 26 the next food source is, so they can tell other bees where to go through their special dance. This amazing ability helps bees work more efficiently and support the whole ecosystem, which is very important for 27 (farm) around the world. 【答案】18．interesting 19．which/that 20．correctly 21．direction 22．by 23．useful 24．on 25．places 26．where 27．farmers 【导语】本文主要介绍了蜜蜂出色的认路本领。它们依靠太阳导航，阴天可借助紫外线定位，还能记住地点、传递食物位置信息，该能力对全球农民意义重大。 【详解】18．考查形容词。句意：蜜蜂最有趣的一点就是它们惊人的回家能力。此处修饰事物things，用-ing形式的形容词interesting，表示“有趣的”。 19．考查定语从句。句意：即使飞到数百公里外的地方，它们也能迅速返回家园。设空处引导定语从句，先行词是 places（地点，指物），从句缺少主语，因此用关系代词which或that引导定语从句，指代先行词并在从句中作主语。 20．考查副词。句意：科学家多年来一直研究这种能力，最终发现蜜蜂能够利用太阳来正确导航。修饰动词navigate（导航）需要用副词形式作状语，correct的副词形式为correctly，表示“准确地导航”。 21．考查名词。句意：通过观察太阳的位置，它们可以准确判断自己需要朝哪个方向飞行。which后接名词，direct的名词形式是direction（方向）；which direction 表示 “哪一个方向”，用单数即可。 22．考查介词。句意：但在阴天、太阳被遮挡的时候，蜜蜂仍能依靠眼睛的特殊部分找到方向。by doing sth是固定搭配，意为“通过做某事”，此处表示“通过使用眼睛的特殊部位来认路”，所以为介词by。 23．考查形容词。句意：这种特殊的能力对蜜蜂来说非常有用，因为即使在恶劣的天气里，它也能帮助它们找到花来获取花蜜。系动词is后接形容词作表语，use的形容词形式为useful，表示“有用的”。 24．考查介词。句意同上。表示在具体某类天气的日子前，介词用on，on bad weather days意为“在天气不好的日子里”。 25．考查名词复数形式。句意：科学家还发现，蜜蜂能够记住不同的地点，并根据太阳位置判断一天中的时间。different（不同的）后接可数名词时，应使用复数形式，因此place变为places。 26．考查宾语从句。句意：它们甚至能辨别下一个食物来源的位置，因此可以通过特殊的舞蹈告诉其他蜜蜂该去的方向。设空处引导宾语从句，从句the next food source is缺少表语，且后文出现where to go呼应地点含义，因此用where引导宾语从句，表示“下一个食物源在哪里”。 27．考查名词。句意：这种令人惊叹的能力让蜜蜂工作更高效，从而支持整个生态系统，这对全球农民来说至关重要。根据句意“这对全世界的农民至关重要”，此处需填表示“农民” 的名词；farmer是可数名词，结合around the world的范围，用复数形式farmers。 五、阅读理解 A In the mountains of Sichuan, a team of scientists is using a new method to protect giant pandas. Instead of tracking the animals in the wild, they collect panda droppings (粪便) and use DNA analysis to identify individual pandas. This helps them count the population without disturbing the animals. “Traditional methods, like following footprints or watching from a distance, are not always accurate,” says Dr. Li, a biologist. “With DNA, we can tell pandas apart — even their family relationships.” The team has already identified over 50 pandas in one forest. They also found that some pandas are isolated in small areas. “If pandas cannot move between forests, they cannot find mates. That is dangerous for their future,” Dr. Li explains. To solve this, the government is building “green corridors” — strips of forest that connect separated habitats. Local villagers are also hired as forest guards. The combination of science and community effort has led to a slow but steady rise in the panda population. 28．What is the advantage of using DNA analysis? A．It is cheaper than traditional methods. B．It can track panda movements in real time. C．It does not disturb the pandas. D．It allows scientists to touch pandas. 29．What problem did the DNA analysis discover? A．Pandas are eating less bamboo. B．Some pandas live in isolated groups. C．The panda population is falling sharply. D．Pandas are attacking local villages. 30．What are “green corridors” meant to do? A．Provide food for pandas. B．Stop tourists from entering panda areas. C．Create new zoos for pandas. D．Help pandas move between forests. 31．What can we learn from the last paragraph? A．Science alone cannot save pandas. B．Local villagers are against panda protection. C．The panda population is still decreasing. D．Green corridors have failed to work. 【答案】28．C 29．B 30．D 31．A 【导语】文章主要介绍科学家借助DNA分析技术调查野生大熊猫，发现栖息地隔离问题，并通过修建绿色廊道开展保护工作。 【详解】28．细节理解题。根据第一段中的“Instead of tracking the animals in the wild, they collect panda droppings (粪便) and use DNA analysis to identify individual pandas. This helps them count the population without disturbing the animals.(他们不在野外追踪这些动物，而是收集熊猫粪便，利用DNA分析识别单独的熊猫个体。这帮助他们统计种群数量，且不会打扰这些动物。)”可知，DNA分析的优势在于不会惊扰大熊猫。 29．细节理解题。根据第三段中的“The team has already identified over 50 pandas in one forest. They also found that some pandas are isolated in small areas.(该团队已经在一片森林中识别出超过50只熊猫。他们还发现，部分熊猫分散孤立在狭小区域内。)”可知，DNA分析发现部分大熊猫处于隔离栖息的状态。 30．细节理解题。根据第四段中的“To solve this, the government is building “green corridors” — strips of forest that connect separated habitats.(为解决这个问题，政府正在修建“绿色廊道”——连接相互分隔栖息地的带状森林。)”以及上文熊猫难以迁徙寻找配偶的问题可知，绿色廊道用来帮助大熊猫在不同森林间迁徙活动。 31．推理判断题。根据第四段中的“The combination of science and community effort has led to a slow but steady rise in the panda population.(科学手段与社区力量相结合，才让大熊猫数量稳步缓慢增长。)”可知，仅仅依靠科学无法拯救大熊猫，还需要社区配合。 B New Year, New Goals: For You and Your Pets The start of a new year is a perfect time for setting new goals — and this should include your pets.

It’s wise to have an emergency plan ready. This includes preparing a pet first-aid kit, learning where the nearest emergency animal hospital is, and keeping your pets’ medical records easy to find. (意外情况随时可能发生，因此提前制定应急计划是明智之举。这包括准备宠物急救包、了解最近的动物急诊医院位置，以及确保宠物的医疗记录易于查找。)”详细列举了准备急救包、寻找最近的急诊动物医院以及妥善保管医疗记录等具体准备工作。E选项“Being ready can help you stay calm and act quickly (做好准备可以帮助你保持冷静并迅速采取行动)”是对上述所有准备工作的意义和目的的总结，强调了“有备无患”在应对突发状况时的重要性，符合题意。 六、完形填空 The air is 37 and we have to rest several times on the short hike from camp. To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch. On the plain in front of us, we can just make out a herd of graceful animals. This is why we’re here — to 38 Tibetan antelopes (藏羚羊). Tibetan antelopes live on the plains of Tibet, Xinjiang, and Qinghai. Watching them move slowly across the green grass, I’m 39 by their beauty. I’m also reminded of the danger they are in. They are being hunted, illegally, for their valuable fur. My guide is Zhaxi, a villager from Changtang. He works at the Changtang National Nature Reserve. The reserve is a 40 for the animals and plants of northwestern Tibet. To Zhaxi, the land is sacred and protecting the wildlife is a way of life. “We’re not trying to save the animals,” he says. “ 41 , we’re trying to save ourselves.” The 1980s and 1990s were bad times for the Tibetan antelope. The population dropped by more than 50 percent. Hunters were shooting antelopes to make 42 . Their habitats were becoming smaller as new roads and railways were built. In order to save this species from 43 , the Chinese government 44 it under national protection. Zhaxi and other volunteers watched over the antelopes day and night to keep them safe from 45 . Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains. The measures were 46 . The antelope population has recovered and in June 2015, the Tibetan antelope was removed from the 47 species list. The government, however, does not intend to stop the protection programmes, since the 48 to the Tibetan antelope have not yet disappeared. In the evening, I drink a cup of tea and watch the stars. I 49 the antelopes and what Zhaxi told me. Much is being done to protect 50 , but if we really want to save the planet, we must change our way of life. Only when we learn to 51 in harmony with nature can we stop being a threat to wildlife and to our planet. 37．A．thick B．thin C．sacred D．valuable 38．A．observe B．remind C．hunt D．move 39．A．trapped B．disappeared C．struck D．reserved 40．A．shelter B．nation C．city D．population 41．A．Gradually B．Safely C．Unfortunately D．Actually 42．A．habitat B．railways C．vehicles D．profits 43．A．protection B．production C．extinction D．exploration 44．A．added B．placed C．reduced D．shot 45．A．attacks B．habitats C．species D．lists 46．A．ineffective B．graceful C．efficient D．effective 47．A．astonishing B．precious C．endangered D．plain 48．A．benefits B．survival C．programs D．threats 49．A．go about B．think about C．talk about D．bring about 50．A．lifeblood B．lifestyle C．wildlife D．lifeboat 51．A．exist B．remove C．recover D．reserve 【答案】37．B 38．A 39．C 40．A 41．D 42．D 43．C 44．B 45．A 46．D 47．C 48．D 49．B 50．C 51．A 【导语】文章主要讲述探访藏羚羊保护区，见证保护工作与生态理念的故事。 【详解】37．考查形容词。句意：空气稀薄，我们在从营地出发的短途徒步中要休息好几次。A. thick浓密的；B. thin稀薄的；C. sacred神圣的；D. valuable有价值的。根据下文“we have to rest several times on the short hike”及“snow-covered mountains”可知，在短途徒步中要休息好几次以及白雪覆盖的山脉，说明高海拔地区空气稀薄导致呼吸困难。 38．考查动词。句意：这就是我们来这里的原因——观察藏羚羊。A. observe观察；B. remind提醒；C. hunt狩猎；D. move移动。根据下文第二段“Tibetan antelopes live on the plains of Tibet, Xinjiang, and Qinghai.

Some species are dying out because their habitats are being destroyed. Every year, some creatures migrate thousands of miles in search of suitable living conditions. The more we know about wildlife, the clearer we see that we must take effective measures to protect them. The main reason why many animals are in trouble is human activity. We should show respect to wild creatures and stop destroying their home. It is humans who are the visitors to their world after all. Small actions matter. We can spread knowledge of animal protection. Only when we live in peace with nature can we enjoy a better world. 译文：保护野生动物，尊重自然 如今很多野生动物面临严峻危险。一些物种濒临灭绝，因为它们栖息地遭到破坏。每年都有生物迁徙数千英里，去寻找适宜生存的环境。 我们对野生动物了解越多，就越清楚必须采取有效措施保护它们。许多动物陷入困境的主要原因是人类活动。我们应当尊重野生动物，停止破坏它们家园。毕竟，人类才是它们世界的访客。 微小行动意义重大。我们可以传播动物保护知识。只有与自然和平共处，我们才能拥有更美好的世界。 易错点01 the solution to sth，介词用 to，不用 of ❌错句：We have found the solution of this wildlife problem. ✅正确：We have found the solution to this wildlife problem. 【错因辨析】 solution, answer, key 后面表 “…… 的” 固定搭配介词 to。 【一句话辨异】 答案、解决办法，介词 to 要记住。 【助记口诀】 key、answer、solution，后面介词用 to 凑。 【对点训练】 What is the best solution ______ the animalprotection problem?

Even after flying to places 19 are hundreds of kilometers away, they can always return to their home quickly. Scientists have studied this ability for years, and they finally found out that bees can use the sun to navigate (导航) 20 (correct). Using the position of the sun, they can tell exactly which 21 (direct) they need to fly. But on cloudy days, when the sun is hidden, bees can still find their way 22 using special parts of their eyes. These special eyes allow bees to see ultraviolet light (紫外线), which humans cannot see. This special ability is very 23 (use) for bees, because it helps them find flowers to get nectar (花蜜) even 24 bad weather days. Scientists also found that bees can remember different 25 (place) and tell the time of day based on the sun’s position. They even can tell 26 the next food source is, so they can tell other bees where to go through their special dance. This amazing ability helps bees work more efficiently and support the whole ecosystem, which is very important for 27 (farm) around the world. 五、阅读理解 A In the mountains of Sichuan, a team of scientists is using a new method to protect giant pandas. Instead of tracking the animals in the wild, they collect panda droppings (粪便) and use DNA analysis to identify individual pandas. This helps them count the population without disturbing the animals. “Traditional methods, like following footprints or watching from a distance, are not always accurate,” says Dr. Li, a biologist. “With DNA, we can tell pandas apart — even their family relationships.” The team has already identified over 50 pandas in one forest. They also found that some pandas are isolated in small areas. “If pandas cannot move between forests, they cannot find mates. That is dangerous for their future,” Dr. Li explains. To solve this, the government is building “green corridors” — strips of forest that connect separated habitats. Local villagers are also hired as forest guards. The combination of science and community effort has led to a slow but steady rise in the panda population. 28．What is the advantage of using DNA analysis? A．It is cheaper than traditional methods. B．It can track panda movements in real time. C．It does not disturb the pandas. D．It allows scientists to touch pandas. 29．What problem did the DNA analysis discover? A．Pandas are eating less bamboo. B．Some pandas live in isolated groups. C．The panda population is falling sharply. D．Pandas are attacking local villages. 30．What are “green corridors” meant to do? A．Provide food for pandas. B．Stop tourists from entering panda areas. C．Create new zoos for pandas. D．Help pandas move between forests. 31．What can we learn from the last paragraph? A．Science alone cannot save pandas. B．Local villagers are against panda protection. C．The panda population is still decreasing. D．Green corridors have failed to work.

To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch. On the plain in front of us, we can just make out a herd of graceful animals. This is why we’re here — to 38 Tibetan antelopes (藏羚羊). Tibetan antelopes live on the plains of Tibet, Xinjiang, and Qinghai. Watching them move slowly across the green grass, I’m 39 by their beauty. I’m also reminded of the danger they are in. They are being hunted, illegally, for their valuable fur. My guide is Zhaxi, a villager from Changtang. He works at the Changtang National Nature Reserve. The reserve is a 40 for the animals and plants of northwestern Tibet. To Zhaxi, the land is sacred and protecting the wildlife is a way of life. “We’re not trying to save the animals,” he says. “ 41 , we’re trying to save ourselves.” The 1980s and 1990s were bad times for the Tibetan antelope. The population dropped by more than 50 percent. Hunters were shooting antelopes to make 42 . Their habitats were becoming smaller as new roads and railways were built. In order to save this species from 43 , the Chinese government 44 it under national protection. Zhaxi and other volunteers watched over the antelopes day and night to keep them safe from 45 . Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains. The measures were 46 . The antelope population has recovered and in June 2015, the Tibetan antelope was removed from the 47 species list. The government, however, does not intend to stop the protection programmes, since the 48 to the Tibetan antelope have not yet disappeared. In the evening, I drink a cup of tea and watch the stars. I 49 the antelopes and what Zhaxi told me. Much is being done to protect 50 , but if we really want to save the planet, we must change our way of life. Only when we learn to 51 in harmony with nature can we stop being a threat to wildlife and to our planet. 37．A．thick B．thin C．sacred D．valuable 38．A．observe B．remind C．hunt D．move 39．A．trapped B．disappeared C．struck D．reserved 40．A．shelter B．nation C．city D．population 41．A．Gradually B．Safely C．Unfortunately D．Actually 42．A．habitat B．railways C．vehicles D．profits 43．A．protection B．production C．extinction D．exploration 44．A．added B．placed C．reduced D．shot 45．A．attacks B．habitats C．species D．lists 46．A．ineffective B．graceful C．efficient D．effective 47．A．astonishing B．precious C．endangered D．plain 48．A．benefits B．survival C．programs D．threats 49．A．go about B．think about C．talk about D．bring about 50．A．lifeblood B．lifestyle C．wildlife D．lifeboat 51．A．exist B．remove C．recover D．reserve 学科网（北京）股份有限公司1 / 10 学科网（北京）股份有限公司 $
