Microplastics(微塑料) in Water—a Wake-up Call for All of Us

【分析】
这是一篇环保主题的七选五句子还原题，解题时首先通读全文，明确文章围绕“水中的微塑料的危害与应对方案”展开，再逐空分析前后文的逻辑关联，匹配对应选项：
1. 第1空：前文提到水中的微塑料肉眼不可见、很难清理，后文递进说明更严重的情况是饮用水中也发现了微塑料，空白处需要承接“水中的微塑料”这一话题，说明它在水环境里的流转路径。
2. 第2空：前文点明“饮用水中存在微塑料引发人们担忧”，后文说明科学家暂未明确它对人体的长期危害，空白处需要衔接“饮用水含微塑料”这件事带来的直接影响。
3. 第3空：后文用for example引出多个微塑料的来源场景，空白处是该段的总起句，需要总领下文关于微塑料来源的举例内容。
4. 第4空：前文点明各国都认同不能过度使用塑料，后文用“We also need to...”引出针对企业的管控措施，空白处要和后文的并列结构呼应，提出我们需要采取的相关行动方向。
5. 第5空：前文发出共同保护环境的呼吁，空白处在全文末尾，需要给出贴合环保主题的行动指引，完成全文收尾。
【解析】
1. 第1空：D选项“When in water, they are eaten by fish and other animals.”（在水中时，它们会被鱼类和其他动物吃掉）承接前文水中的微塑料的属性，说明其在水生态中的流转，和后文“更严重的是进入饮用水”形成递进逻辑，符合语境。
2. 第2空：B选项“This means that we are drinking plastic every day.”（这意味着我们每天都在摄入塑料）里的This指代前文“饮用水中存在微塑料”这件事，自然引出后文科学家对其长期危害的不确定，逻辑连贯。
3. 第3空：C选项“Microplastics come in a number of different ways.”（微塑料有很多不同的来源）作为段首总起句，完美引出后文列举的各类微塑料来源场景，和举例内容完全匹配。
4. 第4空：E选项“We need to find a solution to cleaning microplastics from our oceans.”（我们需要找到将微塑料从海洋中清理出去的解决方案）中的“We need to”和后文的“We also need to”形成并列的行动倡议结构，衔接自然。
5. 第5空：A选项“Remember: Reduce—Reuse—Recycle.”（牢记：减量化、再利用、再循环）是环保领域经典的3R原则，作为全文收尾的行动指引，呼应前文保护环境的呼吁，贴合主题。
多余选项F讲人们喜欢用塑料的原因、G讲微塑料在环境中留存时间长，都无法匹配文中空白处的逻辑位置。
【答案】
1. D 2. B 3. C 4. E 5. A
