The _______ (much) we know about bees, the _______ (much) we will protect them. 答案： most important; best; busiest; sweetest; more; more 解析： 1. most important "one of the + 最高级 + 复数名词"结构。important 是多音节词。 1. best "the + 最高级"结构。good 的最高级是不规则变化 best。 1. busiest "the + 最高级"结构。busy 是辅音 + y 结尾，变 y 为 i 加 -est。 1. sweetest "the + 最高级"结构。sweet 是单音节词，加 -est。 1. more "the + 比较级，the + 比较级"结构。 1. more "the + 比较级，the + 比较级"结构。 2.4 真实场景中的"零信息保留"测试（25分钟） 认知目标：Level 6 创造——在从未见过的真实生活场景中，创造性地运用最高级进行表达。 听力替代训练（教师朗读稿）——"神奇动物在哪里" 教学说明：先让学生阅读 Pre-listening Questions，明确信息抓取目标。教师朗读两遍，学生完成信息记录。 Pre-listening Questions： 1. What animal is being talked about? 1. How heavy can it be? 1. How long can it be? 1. What does it eat? 1. How long can it live? 教师朗读稿： Today, let me tell you about one of the most amazing animals on Earth — the blue whale. The blue whale is the largest and heaviest animal in the world. It can weigh up to 200 tons. That's heavier than 30 elephants! In terms of length, it is also the longest. Some blue whales can be over 30 meters long. That's as long as a basketball court. Blue whales live in all the world's oceans except the Arctic Ocean. They eat tiny sea animals called krill（磷虾）. An adult blue whale can eat up to 4 tons of krill every day. That's about 40 million krill! The most surprising thing is that blue whales can live for a very long time. Scientists say they can live up to 90 years. When a blue whale dies, its body sinks to the bottom of the ocean. There, it becomes food for many deep-sea creatures for over a year. The blue whale is truly one of the most amazing creatures on our planet. The more we learn about them, the more we will love and protect them. Post-listening Check： 1. What animal is being talked about? 答案：The blue whale. 解析：开篇即给出答案。 1. How heavy can it be? 答案：Up to 200 tons. 解析：注意数据表达 up to 200 tons，以及对比"heavier than 30 elephants"。 1. How long can it be? 答案：Over 30 meters long. 解析：注意 over 30 meters 和 as long as a basketball court 的对比表达。 1. What does it eat? 答案：Tiny sea animals called krill. It can eat up to 4 tons every day. 解析：注意区分"吃什么"和"吃多少"两个信息点。 1. How long can it live? 答案：Up to 90 years. 解析：注意 live up to 90 years 这个搭配。 阅读理解——"城市植物园"（原创题） 素材来源：自编题，素材基于 2026 年"城市植物园评比"活动。 Last month, a survey asked visitors about the best botanical garden（植物园）in the city. Three gardens were compared: Green Garden, Rose Park, and Bamboo World. Green Garden is the oldest botanical garden in the city. It opened in 1985. It has the largest collection of plants — over 5,000 different kinds! The most popular part is the cactus（仙人掌）house. It has some of the rarest cacti in the country. Rose Park is the most beautiful garden of the three. It has more than 1,000 kinds of roses. Every spring, the garden is the most colorful place in the city. Many people come here to take photos. The garden is also the most romantic place for couples. Bamboo World is the most educational garden. It has the largest bamboo forest in the city. Visitors can learn about different kinds of bamboo and how people use them. The most interesting thing is that visitors can watch workers make bamboo tools and instruments. It's one of the most popular activities for children. Which garden is the best? It depends on what you are looking for. If you want to see the most plants, go to Green Garden. If you want the most beautiful scenery, choose Rose Park. If you want to learn the most, visit Bamboo World. The more you explore, the more you will enjoy nature! 1.

Here are some of the most interesting examples. The Fastest Train — Learning from the Kingfisher（翠鸟） Japan's Shinkansen bullet train（新干线子弹头列车）was one of the fastest trains in the world. But when it came out of tunnels, it made a loud noise like an explosion. Engineers studied the kingfisher. The kingfisher is one of the most skilled hunters in the bird world. It can dive into water at high speed without making a splash（水花）. The engineers redesigned the front of the train to look like the kingfisher's beak. The new train was not only quieter but also 10% faster and used 15% less electricity. The Strongest Material — Learning from Spider Silk（蜘蛛丝） Spider silk is one of the strongest materials in the world. It is stronger than steel but much lighter. Scientists are trying to make artificial（人造的）spider silk. This material could be used to make the strongest bulletproof vests（防弹衣）and the lightest medical tools. The Best Flyer — Learning from the Hummingbird（蜂鸟） The hummingbird is one of the most amazing flyers. It can fly forward, backward, and even hover（悬停）in the air. Scientists have made tiny flying robots that move like hummingbirds. These robots could be used for the most dangerous rescue（救援）missions. Nature is the best teacher. The more we learn from animals, the better our technology will be. 1. What problem did the Shinkansen bullet train have at first? A. It was too slow. B. It made a loud noise when coming out of tunnels. C. It used too much electricity. D. It was too heavy to move fast. 1. Which animal did engineers study to solve the train's noise problem? A. The spider. B. The hummingbird. C. The kingfisher. D. The cheetah. 1. What makes spider silk a special material? A. It is the heaviest natural material. B. It is stronger than steel but much lighter. C. It is the most expensive material on Earth. D. It can only be used for making clothes. 1. What is the main idea of this passage? A. Animals are not useful for modern technology. B. Nature can teach us to develop better technology. C. The hummingbird is the most amazing animal. D. Spider silk is the most dangerous material. 答案： 1. B 2. C 3. B 4. B 详细解析： 第1题 答案：B 原文"when it came out of tunnels, it made a loud noise like an explosion"。干扰项分析： A（too slow）与原文"one of the fastest"矛盾；C（too much electricity）改进后省电15%，但原文未说之前耗电过多是问题；D（too heavy）原文未提及。 第2题 答案：C 原文"Engineers studied the kingfisher"。干扰项分析： A（The spider）出现在仿生材料部分；B（The hummingbird）出现在仿生飞行器部分；D（The cheetah）本文未提及。 第3题 答案：B 原文"Spider silk is one of the strongest materials in the world. It is stronger than steel but much lighter。"干扰项分析： A（heaviest）与原文"lighter"矛盾；C（most expensive）原文未提及；D（only for clothes）与原文"bulletproof vests and medical tools"矛盾。 第4题 答案：B 文章最后一句"Nature is the best teacher. The more we learn from animals, the better our technology will be."点明主旨。干扰项分析： A（not useful）与主旨相反；C（most amazing）过于片面；D（most dangerous）与原文矛盾。 4.3 思维拓展（10分钟） 四、语篇建构（10分） 题目：假设你是李华，你的英国笔友 Mike 来信想知道你最神奇的动物。请根据以下提示写一封回信。 要点提示：1. 你选择哪种动物；2. 用最高级描述它的特征（至少3个维度）；3. 为什么觉得它神奇。 要求：80 词左右；使用最高级结构，至少使用 4 次；三段式结构（开头-主体-结尾）。 参考范文： Dear Mike, Thank you for your letter. You asked about the most amazing animal I know. Let me tell you about the blue whale. The blue whale is the largest and heaviest animal on Earth. It can weigh up to 200 tons, much heavier than any land animal. It is also the longest. Some blue whales are over 30 meters long. The most surprising thing is that it can live up to 90 years. Blue whales are truly one of the most amazing creatures in the world. I think nature is the best teacher. The more we learn about animals, the more we will love and protect them.
