But they contain very small plastic fibers, which may also be harming the environment when you wash them. When people wash these clothes, very small pieces go down the drain(下水道) with the wash water.5_Pollution caused by plastic is not new, but recent studies have shown the effect of microfibers in the environment. Studies show very small microfibers are ending up in our waters, which may come from waste water treatment factories. A 2015 study found them in fish from California.Microfibers effect on food supplies.Beyond the waterways, the researchers say microfibers may end up in soil and agricultural lands.6_ This means there is much to be learned about microfibers and the environment.Some studies have shown that microfibers end up inside sea animals, like oysters.7_ Researchers say that the fibers tend not to move into the tissue of the fish, but it needs more study.Steps to save or keep microfibers from the environment.Until more information becomes known, there are steps to take to reduce the amount of microfibers in the environment.People should use less of the artificial materials. If we already have those in our lives and were using them, an important step would be washing them less.8_ A bag is being designed in which you can wash these clothes. The bag traps the microfibers in it and it may be available for purchase soon.ANew technology may also help.BStudies on how much of the microfibers are released.CThe source of these microfibers may surprise you: your clothes.DWashing machines keep microfibers from escaping with wash water.EStudies on microfibers in the environment.FThey can also move around the atmosphere.GSo if these microfibers have been found in fish and seafood, are they safe to eat?语篇导读本文为说明文，主要介绍了微纤维的来源、微纤维对环境和食物供应的影响以及减少微纤维进入环境的措施。4解析 C顺承关系。由文章标题Are Your Clothes Causing Pollution？可知，本文与衣服导致污染有关，并结合下文可知，造成污染的微纤维来自于有些用人工材料制成的衣服，故选C项。5解析 E总分关系。根据文章结构可知，空处为该部分小标题。空后的段落主要讲的是微纤维对环境的影响，故选E项。6解析 F并列关系。结合空前一句中的the waterways和in soil and agricultural lands可知，研究人员认为微纤维可能扩散到下水道、土壤和农田中，故选F项(它也能在大气中移动)。7解析 G顺承关系。空前一句中的sea animals, like oysters与G项中的fish and seafood相呼应，故选G项。8解析 A总分关系。空后一句中的A bag is being designed正是A项中的New technol
