题目

阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。 To be clear, plastic bags are rightly thought of as a threat that's harmful to human health. According to the National Resources Defense Council, over a decade ago, the average American family took home almost 1,500 plastic shopping bags a year, filling our cabinets, kitchen drawers, and landfills (垃圾填埋场). Today the numbers are slightly better: According to National Geographic, as of 2018, shoppers in the United States use almost one plastic bag per resident per day. This is not a story on the evil of plastics, but on whether the reusable bag can justify its existence. Although more environmentally friendly than traditional single-use plastic bags, reusable bags, depending on what they are made of, are more energy-intensive (耗能) to recycle. According to a report by the United Nations Environment Program, "depending on what they are made of, reusable bags might have to be deconstructed in a costly recycling process to separate the different materials. As a result, in many cases, reusable bags are not recycled." That means despite the best intentions, millions of reusable bags designed to replace the need for traditional plastic shopping bags, will also end up in landfills. Another point to consider, not all reusable bags are equal in terms of their recyclability. There are a wide range of reusable bag options on the market, and reusable bags tend to be made of more than one material to give the bag added reinforcement (耐用) and added street fashion. On a life cycle basis, stronger, heavier bags-no matter what material they are made of-will have a more severe environmental effect. That's because heavier bags use more resources to produce as well as distribute. Just like plastic bags did, reusable bags multiply rapidly. Used for promotional (促销的)purposes and marketing of all kinds, reusable bags' growing popularity means bags that have been used very little (or not at all) can be found piled in streets, in garbage cans in city parks, and basically everywhere. Therefore, consumers have come to see them as disposable, defeating their very purpose. In the end, the best practice for reusable bags is to have no half measures: Either use them all the time or don't use them at all. Using a reusable bag once or twice, and then throwing it away, doesn't do the environment any favors. （1） What can we learn from the passage? A . Plastic bags are refused by environmentalists. B .
