一、阅读七选五
Plastics are very common in our daily life. We use them to pack food, keep things safe and make many daily things. Scientists even find small plastic pieces in Arctic snow and far-away deserts—these are microplastics. 1.
◆ Microplastics in Our Environment.
Microplastics are very small pieces less than 5 mm in size. 2. They can be found in oceans, air and soil easily. And these microplastics are hard to be removed from the environment.
◆3.
Microplastics bring big problems to human health. When they get into our bodies, they can harm our endocrine system(内分泌系统). They can also carry harmful chemicals into our bodies and make us get sick easily.
◆ Microplastics in Our Daily Life.
We take in microplastics in many ways every day. First, we breathe them in from the air. Second, many clothes are made of man-made materials. Washing these clothes makes plastic pieces fall off, which become microplastics. 4. For example, millions of microplastics are in the oceans, so fish may eat them. Some tea bags are made of plastic, and hot water lets microplastics into our drinks.
All in all, microplastics are everywhere around us. They are not only in the air and the food, but also in the water we drink. But they are harmful to both humans and the Earth. 5.
A. The Harmful Chemicals in Plastics.
B. Microplastics and Human Health.
C. Here are some facts about microplastics.
D. So we should use less plastic to protect our health and the Earth.
E. They come from big plastics breaking into small parts over time.
F. Third, microplastics can enter our bodies through the food we eat.
G. Drinking more cold water can take microplastics out of our bodies.

【分析】
先通读全文，明确文章主旨是介绍微塑料的相关事实（定义、来源、危害、日常摄入方式及应对）。解题时需结合上下文的逻辑关系（总起、分述、总结、并列等），分析每个空缺处前后的内容，匹配对应的选项：1. 空1后是分述的小标题，需总起引出微塑料的相关事实；2. 空2前是微塑料的定义，后是其分布，需补充来源；3. 空3是小标题，对应后文对人类健康的危害；4. 空4前是摄入方式的前两点，需补充第三点；5. 空5前是危害总结，需提出应对措施。
【解析】
1. 空1：前文引出微塑料，后文是关于微塑料的多个方面介绍，选项C“Here are some facts about microplastics”起到总起下文的作用，符合逻辑，故选C；
2. 空2：前文定义微塑料是小于5mm的小碎片，后文讲其分布，选项E“They come from big plastics breaking into small parts over time”说明微塑料的来源，衔接自然，故选E；
3. 空3：该空为小标题，后文内容是微塑料对人类健康的危害，选项B“Microplastics and Human Health”概括了该段主旨，故选B；
4. 空4：前文列举了两种摄入微塑料的方式（呼吸、洗衣服），选项F“Third, microplastics can enter our bodies through the food we eat”补充了第三种摄入方式，符合并列逻辑，故选F；
5. 空5：前文总结微塑料的危害，选项D“So we should use less plastic to protect our health and the Earth”提出应对措施，符合总结逻辑，故选D。
