首先通读全文，明确本文围绕中学生超重的健康问题展开，介绍了政府为改善该问题推出的相关举措，以及部分学生的不同态度。解题时逐空定位前后文的逻辑线索：
1. 第一空前文提到超重不仅是外貌问题，更是健康问题，接下来需要顺承说明超重会引发的健康危害，匹配对应选项。
2. 第二空前文提到政府要求学校做出更多行动，后文紧接着列举学校在食堂供餐、体育课程上的具体调整，因此此处需要填入引出学校做出改变的过渡句。
3. 第三空前文提到政府通过宣传广告科普健康生活，后文列举了广告出现在电视、网络、公交等各个场景，对应描述广告分布广泛的选项。
4. 第四空前文提到部分学生不认可这些举措，后文说明学生认为自己有权自主决定饮食和运动量，对应解释学生抵触原因的选项。
5. 第五空位于全文结尾，前文总结政府推进相关工作并不容易，此处需要填入收尾、向读者发起提问的句子，完成语篇闭环。
【解析】
1. 空前指出超重不只是外貌问题，更关乎健康，E选项“它会引发像心脏病这类问题”顺承说明超重带来的健康危害，逻辑衔接通顺。
2. 空前说明政府要求学校做出更多行动，后文列举学校的各项调整举措，C选项“学校开始做出改变”起到承上启下的过渡作用。
3. 空前提到政府投放宣传健康生活的广告，后文列举广告出现在各类公共场景，B选项“这些广告随处可见”呼应后文的多场景描述。
4. 空前提到部分学生不喜欢这些举措，后文说明学生认为自己可以自主决定饮食和运动安排，F选项“学生不喜欢被人指使该做什么”准确解释了学生抵触的原因。
5. 前文总结政府助力学生健康的工作并不容易，A选项“你对此的看法是什么？”放在文末发起互动提问，符合语篇收尾逻辑。

At first the problem was not so serious because there was plenty of clean air，land and water. 3. All the dirty things could be absorbed(吸收) by nature and soon be covered over.

Through the use of poison(毒药)，humans have polluted land and killed the animals. By putting dirty water and chemicals into rivers and lakes，we have polluted our drinking water，killing the fish. 4. More people，more waste.
Are we turning the world into a big rubbish dump，or is there any hope that we can get rid of pollution? 5. Many people are working hard to control it.
A. Pollution comes in many ways. B. Humans couldn’t probably live on the earth.

这是一篇关于污染主题的说明文七选五题型，解题时首先通读全文，梳理出文章“定义污染→追溯污染的发展历程→点明污染现状→给出污染治理的希望”的整体行文脉络，之后逐空分析前后文的逻辑关联：先看每空前后的内容提示，匹配语义衔接最顺畅的选项，排除逻辑冲突的选项，最后代入全文验证整体通顺度即可得出答案。
【解析】
1. 第一空：前文给出污染的定义，后文列举“我们能看见污染、闻到污染、尝到污染、喝到被污染的东西”，说明污染的存在形式十分多样，A选项“Pollution comes in many ways.”完全承接上下文语义，故选A。
2. 第二空：前文提到人类从学会生火、在河里洗衣、随地扔垃圾的阶段就已经开始污染地球，后文说明早期污染问题并不严重，因为当时有充足的清洁资源，F选项“When land was used up or water became dirty, humans moved to another place.”符合早期人类逐资源迁徙的活动特点，承接早期污染行为的描述，引出后文早期污染不严重的背景，故选F。
3. 第三空：前文点明早期有大量清洁的空气、土地和水资源，后文提到所有污染物都可以被自然吸收消解，D选项“There weren’t so many people then and their wants were fewer.”进一步解释早期污染程度低的核心原因，逻辑链条完整通顺，故选D。
4. 第四空：后文直接给出提示“More people，more waste.”，C选项“Our increasing population is part of the problem.”正好点出人口增长和污染的关联，衔接前文对土地、水源污染的描述，引出后文人口和垃圾的对应关系，故选C。
5. 第五空：前文抛出设问“我们要把世界变成大型垃圾场吗，我们还有希望消除污染吗”，后文提到很多人正在努力管控污染，E选项“Luckily，millions of people have been warned of the danger of pollution.”给出设问的正向回应，承上启下引出后文的治污行动，故选E。
