(1)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. (2)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.
未听先知
预览两道题各选项,由 mobile phone(s)、 network device等词可以初步推测,新闻内容与移动网络 或设备有关。第1题各选项均是动词短语,可能考查计划或建议,且本题选项中反复出现了 the moon,可推测本题 考查的计划或建议与月球有关;第2题选项句式结构相同,用形容词表特征,可能考查移动网络或设备的特点。
详解详析
1. What are scientists planning to do?
C)。详解新闻开头提到,2019年,科学家们将在月球上布设第4代或者4G移动网络。如果成功的话 月球将首次覆盖移动电话网络。由此可知,科学家们计划在月球上布设移动电话网络,答案为C)。
2. Why did scientists choose to set up a 4G network in their mission?
A)。详解新闻末尾提到,科学家们计划在月球上布设4G网络而不是第5代或是5G网络,因为第5代 网络系统目前仍处于测试阶段,如果布设在月球上可能会不够稳定。由此可推断,科学家们之所以选用 4G网络是因为其稳定性好,答案为A)。
