【分析】
这是一篇关于水资源的说明文，解题需结合上下文逻辑关系匹配选项：
1. 第16题：前文以“Why”提问地球看起来呈蓝色的原因，根据英语中用“Because”回应why问句的逻辑，应选解释原因的对应选项。
2. 第17题：后文提到“所以我们每天需要喝大量水”，前文需说明身体需要补水的原因，即水分流失的情况，以此建立因果逻辑。
3. 第18题：前文列举了人们日常用水、农民用水的场景，此处应延续列举不同主体的用水用途，让语篇衔接自然。
4. 第19题：前文说人们对水的需求越来越大，后文提到科学家担忧未来水资源不足，中间需转折说明水资源现状不如从前，引出担忧的原因。
5. 第20题：前文讲污水让干净水变脏，此处应进一步说明水污染带来的其他危害，递进阐述污染的影响。
【解析】
1. 第16空：上句用“Why”提问地球呈蓝色的原因，选项C“Because water covers almost three quarters of the earth.”用Because直接回应原因，符合逻辑，故选C。
2. 第17空：下句“So we need to drink plenty of water every day.”是结果，选项A“As we all know，our body loses water when we exercise or go to the toilet.”解释了需要补水的原因，因果关系成立，故选A。
3. 第18空：前文依次介绍了人们日常饮水、用水清洁做饭，农民用水种庄稼，选项E“Factories use it to make all kinds of things.”延续列举不同主体的用水场景，衔接连贯，故选E。
4. 第19空：前文“After the 1950s，people in the world need more and more water.”，后文“Scientists worry about it. They think there may not be enough water for us in the near future.”，选项B“But there is not as much water as years before.”通过转折衔接需求增加和水资源不足的矛盾，引出担忧，故选B。
5. 第20空：前文“Now，ships and factories are putting wastes and chemicals into seas，rivers and lakes. This can make a lot of clean water dirty.”，选项D“It can also kill fish and some other animals.”进一步说明水污染的危害，递进逻辑合理，故选D。
