【正确答案】 C

【答案解析】[听力原文] A device that weighs less than one kilogram is part of a mission that will allow scientists to deliver fourth generation or 4G mobile coverage to the moon in 2019. If successful, the tiny device will provide the moon with its first ever mobile phone network. The lunar network will support high-definition streaming of video and data between the moon and earth. The network is part of a mission to the moon. This is a project with the goal of landing the first privately paid for mission to the moon. The 4G mission is set to launch from Cape Canaveral in the United States on a space X Falcon 9 rocket in 2019. Mission to the moon intends to establish and test the first elements of a communications network on the moon. The scientists working on the project opted to build a 4G rather than a fifth generation or 5G network. This is because fifth generation networks are still in testing and trial phases. This means that a 5G network may not yet be stable enough to work on the moon's surface. What are scientists planning to do? 本题问科学家们计划做什么。新闻开篇提到，一个不足1公斤重的设备是一项任务的一部分，借助该任务科学家有望于2019年在月球上覆盖4G网络(deliver...4G mobile coverage to the moon in 2019)。而如果任务成功，这个微型设备将为月球提供第一个移动电话网络(provide the moon with its first ever mobile phone network)。综合以上信息可推断，C“在月球上建立移动电话网络”与新闻表述相符，其中的mobile phone network是新闻原词的复现，为答案。 A“让一艘宇宙飞船在2019年登陆月球”中的a space vehicle新闻中未提及，故排除。B“设计新一代手机”利用录音原词generation和mobile phone制造干扰，新闻说的是在月球上覆盖4G网络，并未提及设计新一代手机，故排除。D“借助一个微型设备从月球收集数据”有一定干扰性，其中的data和tiny device均为录音原词。新闻中提到科学家借助tiny device为月球提供移动电话网络，而不是从月球上收集数据，故排除。

【正确答案】 A

【答案解析】[听力原文] Why did scientists choose to set up a 4G network in their mission? 本题问科学家在任务中选择建立4G网络的原因。新闻结尾处提到，参与该项目的科学家选择建立4G网络而非5G网络的原因在于，5G网络仍处在测试阶段(still in testing and trial phases)，这意味着5G网络可能还不够稳定(may not yet be stable enough)，无法在月球表面上运营。据此可反推，之所以选择建立4G网络是因为它足够稳定，故A为答案。 B“它耐用”、C“它不贵”和D“它精密”在新闻中均未提及。
