【正确答案】 B

【答案解析】[听力原文] Scientists are preparing to launch the world's first machine to clean up the planet's largest mass of ocean plastic. The system, originally dreamed up by a teenager, will be shipped out this summer to the Great Pacific Garbage Patch, between Hawaii and California, and which contains an estimated 1.8 trillion pieces of plastic. It will be the first ever attempt to tackle the patch since it was discovered in 1997. The experts believe the machine should be able to collect half of the detritus in the patch—about 40,000 metric tons—within five years. In the past few weeks they have been busy welding together giant tubes that will sit on the surface of the sea and form the skeleton of the machine, creating the largest floating barrier ever made. The Great Pacific Garbage Patch spans 617,763 sq miles—more than twice the size of France, and contains at least 79,000 tons of plastic, research found last month. Most of it is made up of 'ghost gear'—parts of abandoned and lost fishing gear, such as nets and ropes—often from illegal fishing vessels. Ghost gear kills more than 100,000 whales, dolphins and seals each year, according to scientific surveys. Seabirds and other marine life are increasingly being found dead with stomachs full of small pieces of plastic. Creatures eat plastic discarded in the sea thinking it's food but then starve to death because they are not feeding properly. Others are trapped and die of starvation or are strangled or suffocated by ghost gear. What are scientists preparing to do? 题干问的是科学家们准备做什么。短文提到，科学家们正准备推出世界上第一台能大规模清理海洋塑料的机器，故答案为B。科学家们准备推出的是能大规模清理海洋塑料的机器，而不是计划，故排除A项(启动一个关于大规模清理海洋塑料的项目)。科学家们推出的机器是用来清理海洋塑料，而不是保护海洋生物，故排除C项(推出世界上第一台保护海洋生物的机器)。D项(推出防止海洋污染的计划)短文未提及，故排除。 预读三道题的各个选项，根据选项中的clean up，ocean plastic，marine life，fishing nets，starvation，suffocated等词可以预测，短文内容可能与海洋塑料垃圾的清理有关，可能涉及海洋塑料垃圾的现状、产生的影响、解决方法等内容。

【正确答案】 C

【答案解析】[听力原文] Which of the following isn't included in the 'ghost gear'? 题干问的是下列哪一项不含于“废弃工具”当中。短文提到，“废弃工具”包括废弃的捕鱼工具，A项(渔网)、B项(渔线)和D项(渔竿)均是捕鱼工具，由此可知，答案为C(渔船)。

【正确答案】 C

【答案解析】[听力原文] According to the passage, which one is not the reason for the death of marine life? 题干问的是根据短文内容，以下哪一项不是海洋生物死亡原因。短文最后提到，海鸟和其他海洋生物死于吞食塑料垃圾的事例也越来越常见；海洋生物误食遗弃在海面上的塑料，之后却因为进食不当而饿死；还有许多生物要么是被困住后饿死，要么是被废弃工具缠住窒息而死。由此可知，A项(它们饿死)、B项(它们被废弃工具缠住窒息而死)和D项(它们误食了遗弃在海面上的塑料)均符合题意，只有C项(被人类捕杀)未曾提及，故答案为C。
