【分析】
这是一道英语语篇补全的六选五题型，解题时首先要通读全文，明确文章主题是地球博物馆介绍地球的自然生态价值、当前面临的人为破坏，最终呼吁人们保护自然。接下来逐空定位前后文的逻辑线索：
1. 先观察46空后句的指代提示“maybe you'll see them all one day”，说明空缺处要提及多个可供参观的对象；
2. 47空前后分别介绍森林的属性、人类破坏森林的行为，空缺处需要补充森林的价值，形成“森林很重要-人类却破坏它”的转折逻辑；
3. 48空前后分别讲海洋的生态作用、海洋生物被塑料伤害的现状，空缺处需要引出海洋被污染的过渡内容；
4. 49空前文提到冰川融化、海平面上升，空缺处要对应海平面上升带来的直接后果；
5. 50空位于尾段段首，需要总起收尾，呼应全文守护地球家园的主题，最后排除多余选项即可得到全部答案。
【解析】
46. 后文的代词them指代空缺处提到的复数事物，C选项“地球上有很多令人惊叹的地方”引出下文要介绍的森林、海洋、极地等多个地点，完全匹配后句“你有机会把它们都看遍”的表述，故选C。
47. 前文点明森林是全球过半动植物的家园，后文转折指出人类正在大肆破坏森林，E选项“树木净化空气，产出我们呼吸所需的氧气”介绍了树木对人类的核心价值，承接前文森林的重要性，和后文人类破坏森林的行为形成强烈反差，逻辑连贯，故选E。
48. 前文介绍海洋调节全球温度的重要作用，后文描述鱼类误食塑料袋死亡的污染危害，F选项“我们在陆地上产生的很多废弃物污染了海洋”作为过渡句，自然引出后文海洋塑料污染的具体表现，故选F。
49. 前文说明人类使用的燃料让地球升温，冰川融化、海平面上升，A选项“陆地就会消失”是海平面上升带来的直接后果，符合因果逻辑，故选A。
50. 尾段是全文的收尾呼吁，B选项“这是一个绿色的世界”总起本段，引出后文“人们应当保护自然、健康长寿生活”的倡议，呼应全文守护地球家园的主题，故选B。
【答案】
46. C 47. E 48. F 49. A 50. B

【分析】
做这类词形转换的语篇填空题，首先第一步要通读全文，把握短文主旨是介绍仿生学的各类应用，明确整体时态为一般现在时为主。接下来逐个分析每个空格的句子结构：先判断空格处所需的词性、成分，再结合括号内给出的原词，对应考点判断变形方向，比如看到these要考虑名词变复数、介词by后面要接动名词、动词前面要用副词修饰等，最后把所有答案代入通读全文，验证语法通顺、语义连贯即可。
【解析】
51. 此处表达“被叫做仿生学的课题”，name和被修饰的subject是被动关系，用过去分词named作后置定语，表“被命名为……的”。
52. 指示代词these后要接可数名词复数，shape的复数形式为shapes。
53. 动词help后要接人称代词宾格作宾语，主格they对应的宾格是them。
54. 句中助动词don't提示主语为复数，leaf的复数变化是把f改v加es，即leaves。
55. 句中已有be动词are，构成现在进行时结构be+doing，make要变为making。
56. 此处泛指蝴蝶这一类生物，要用可数名词复数，且句首单词首字母大写，填Butterflies。
57. 此处是固定搭配need sth to do sth，用不定式作目的状语，填to stay。
58. 主语nature是第三人称单数，一般现在时中谓语动词要用三单形式，have的三单是has。
59. 介词by后面要接动名词作宾语，和并列的learning保持形式一致，watch变为watching。
60. 此处要修饰动词work，需要用副词，形容词good对应的副词是well。
【答案】
51. named 52. shapes 53. them 54. leaves 55. making 56. Butterflies 57. to stay 58. has 59. watching 60. well
