(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 SpaceX 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. (2) 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.
Questions 1 and 2 are based on the news report you have just heard.
1. What are scientists planning to do?
2. Why did scientists choose to set up a 4G network in their mission?
选项
A、Land a space vehicle on the moon in 2019.
B、Design a new generation of mobile phones.
C、Set up a mobile phone network on the moon.
D、Gather data from the moon with a tiny device.
答案
C
解析
题干问的是科学家们计划做什么。新闻开头提到,一个小型设备可以帮助科学家们实现在月球上覆盖4G网络,故答案为C(在月球上覆盖移动手机网络)。A项(2019年在月球上着陆一个太空飞行器)、B项(设计新一代的移动手机)和D项(用一个微型设备从月球上收集数据)新闻中均未提及,故排除。
