【正确答案】
A
【答案解析】[听力原文] W: There will be more plastic than fish in the world's oceans by 2050 unless more recycling takes place. That is what a new report from the World Economic Forum and Ellen MacArthur Foundation warns. If the current trend continues, the report said, oceans will contain one ton of plastic for every three tons of fish in 10 years. By 2050, plastics will weigh more than fish, and oceans have to hold more plastic than fish, the report said. The problem is that each year at least 8 million tons of plastics end up in oceans around the world. This is the same as dumping the contents of one garbage truck into the ocean every minute. M: Not all plastic ends up in the ocean because someone throws a plastic bottle into the water. Plastic containers and other trash thrown onto streets and sidewalks are often swept into oceans. Unlike other types of trash in the ocean, the plastic never bio-degrades. That means it does not break down. W: There is a way to slow the amount of plastics going into the oceans—people can recycle more. That is a major recommendation of the report by the World Economic Forum and Ellen MacArthur Foundation. The report's authors say that currently only about 14 percent of plastics are recycled. It said research in Europe shows as much as 53 percent of plastic could be recycled using available technology. M: The report says that another solution is using less plastic for packaging products. But that is not likely to happen, the report's authors say. 'Given plastic packaging's many benefits, both the likelihood and desirability of a drastic reduction in the volume of plastic packaging used in our daily life is clearly low,' the report said. But the authors note reducing the use of plastics should be tried 'where it is possible.' W: For decades, scientists warned that plastics are killing fish. The Natural Resources Defense Council said research shows that fish are dying from choking after eating plastics. Another cause of death is that plastics cause 'blockage of digestive system and starvation,' the environmental group said. What is the main problem mentioned in the report? 录音开头提到2050年海洋里的塑料将比鱼更多，接着说这是一份来自世界经济论坛和艾伦·麦克阿瑟墓金会的新报告所发出的警告，也就是说，“海洋中的塑料将会比鱼多”即为该报告所讲的主要问题，故选A。 B“越来越多的鱼将会死于饥饿”是问题的后果；C“人们使用越来越多的塑料”是问题产生的原因，因此B、C项错误。D“世界各地的海洋被过度捕捞”，录音未提到，故排除。
【正确答案】
B
【答案解析】[听力原文] According to the report, how can the problem be solved? 选项都是by doing...结构，预测问题可能问方式、方法或途径。录音中提到，问题的解决方式是回收塑料和减少塑料包装的使用。B“通过回收塑料”与之相符，故为本题答案。 C“发展可用的技术”颇具干扰性，录音提到欧洲的研究发现借助可利用的技术能让塑料的回收率高达53%，可这里的核心还是提高回收率，而非现有的可用技术，故C不对。录音没有提及捕捞问题和开发海洋资源问题，故A和D排除。
