B endangered 解析：句意为“大熊猫是______动物。我们必须保护它。” 结合语境和常识，大熊猫是“濒危的”动物。知识清单在“动物特征与行为”部分明确列出endangered为“濒危的”，并标注为“常考环保话题词汇”。 2. B sight 解析：句意为“鹰有极好的______。它们能从高空中看见小动物。” 根据“see”（看见）可知，此处应填“视力”。知识清单在“动物身体部位与能力”部分列出sight，释义为“视力；看见”，例句为“Eagles have excellent sight.” 3. C rare 解析：句意为“这种花非常______。你只能在这座山上找到它。” 根据“只能在这里找到”可知，它是“稀有的”。rare意为“稀有的；罕见的”。清单中列出其反义词为common（常见的）。 4. C harm 解析：句意为“我们不应该______野生动物。它们是我们的朋友。” 根据“它们是朋友”和常识，应选择“伤害”。harm在清单中释义为“伤害；损害”，符合语境。protect（保护）与句意相反。 5. B the largest 解析：句意为“蓝鲸是海洋中______动物。” 蓝鲸是已知最大的动物，在特定范围内（海洋）比较，应用最高级the largest。知识清单语法部分重点讲解了最高级的构成和用法，形容词最高级前必须加the。 6. A feed on 解析：句意为“熊猫主要以竹子为食。” feed on是固定短语，意为“以……为食”。知识清单在“重点短语与句型”板块明确列出feed on，并给出例句“Pandas mainly feed on bamboo.” 7. B to protect 解析：句意为“保护环境是我们的责任。” 考查It is one's duty to do sth.这一句型，意为“做某事是某人的责任”。to protect是不定式作真正主语。清单在“高分句型”部分列出了It is one’s responsibility to…，与此句型结构一致。 8. C How 解析：句意为“猎豹跑得真快啊！” 这是一个感叹句，中心词是副词fast，应用How引导感叹句，结构为How + 形容词/副词 + (主语+谓语)!。清单在“表达比较与惊叹的实用句型”中列出了该结构。 9. C alive 解析：句意为“这只鸟还______。我们应该帮助它。” 根据“帮助它”可知，鸟是“活着的”。alive意为“活着的”，是表语形容词，常用作表语。清单在“易混淆词汇辨析”中区分了alive（作表语）和living（多作定语）。 10. A made of 解析：句意为“这张桌子是木头做的。” 考查be made of和be made from的区别。be made of表示“由……制成”（能看出原材料），be made from则表示“由……制成”（看不出原材料）。桌子能看出是木头，故选made of。清单在“重点短语”板块明确区分了这两个短语。 第二部分：完形填空（共10小题，每小题1分，满分10分） 11. B tiny 解析：前句提到“有些很大（huge）”，后句用and some are…形成对比，因此应填“很小”。tiny意为“极小的”，与huge（巨大的）形成对比。 12. B long 解析：巨嘴鸟（toucan）以长而色彩鲜艳的喙闻名，因此long beak（长喙）符合常识和上下文。thick（厚）、short（短）、small（小）均不典型。 13. C feed on 解析：句意为“巨嘴鸟以水果和昆虫为食。” 描述动物的食性，用固定短语feed on。清单中多次强调此短语。 14. A aggressive 解析：句意为“它们并不______，但很擅长在树间飞行。” but表示转折，后句描述其能力，前句应描述性格或攻击性。aggressive（好斗的、有攻击性的）符合转折逻辑。intelligent（聪明的）与后句不构成转折。 15. B fierce 解析：句意为“它是一种______的猎手，非常强壮。” 美洲豹是顶级掠食者，因此fierce（凶猛的）符合其特点。gentle（温和的）相反。 16. A sight 解析：与hearing（听力）并列，描述感官能力。美洲豹作为猎手，通常拥有极佳的“视力”（sight）。清单中sight释义为“视力”。 17. B speed 解析：句意为“它们能以高______奔跑来捕捉食物。” at high speed是固定搭配，意为“高速地”。清单中speed的例句为“at a high speed”。 18. B danger 解析：句意为“许多雨林动物现在处于______中。” 根据后文“它们的家园正在消失”可知，它们处于“危险”中。in danger是固定短语，意为“处于危险中”。 19. C protect 解析：句意为“我们必须______这些动物和它们的生存环境。” 根据“必须”和语境，应采取积极行动“保护”。protect是核心词汇。 20. A disappear 解析：句意为“如果我们不采取行动，一些动物可能会永远______。” 与前文“处于危险中”呼应，最严重的后果是“消失”或“灭绝”。disappear意为“消失”。清单中列有die out（灭绝），disappear是近义表达。 第三部分：阅读理解（共15小题，每小题2分，满分30分） A篇 21. F 解析：文中第一句是“The elephant is the largest land animal.”（大象是最大的陆地动物）。最大的动物是蓝鲸（海洋动物）。知识点：最高级的范围限定。 22. T 解析：文中明确提到“Elephants use their trunks to drink water.” 23. F 解析：文中明确提到“They are very intelligent.” 24. F 解析：文中明确提到“Elephants live in groups.” 25. T 解析：文中最后一句提到“they can be dangerous if they feel threatened.” 26.

C For their fins. 解析：第三段第二句提到“People hunt sharks for their fins, which are used to make shark fin soup.” 29. B Make laws to stop hunting. 解析：第四段第二句提到“Laws should be made to stop shark hunting.” 30. C They should be protected. 解析：全文观点明确，从“important”到“should protect”，都在强调保护鲨鱼。 C篇 31. C 91 cm 解析：第二段第二句明确提到“Some kinds of bamboo can grow up to 91 cm in just one day!” 32. B It produces more oxygen. 解析：第三段第一句明确提到“It produces more oxygen than most trees and helps clean the air.” 33.

C It’s very interesting. 解析：上句问“你在读什么？”，下句是“一本关于动物的书。”此处自然应对书的内容进行评价。 57. A They are very intelligent. 解析：上句问“你最喜欢哪种动物？”，答“海豚。”此处应开始阐述喜欢的原因或海豚的特点。下句接着问“海豚能做什么？”，所以此处宜先概括其智能特点。 58.

It has a cute black-and-white body and looks very gentle. Pandas are not only lovely but also a symbol of China. I like pandas because they are peaceful and interesting. They spend most of their time eating bamboo. Sadly, they are endangered animals because their living areas are getting smaller. To protect pandas, we should protect their forests and not harm them. We can also tell more people about the importance of pandas. It is our duty to protect these amazing animals and let them live happily in the wild. 1 学科网（北京）股份有限公司 $
