(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、It is stable.
B、It is durable.
C、It is inexpensive.
D、It is sophisticated.
答案
A
解析
题干问的是为什么科学家们在任务中选择覆盖4G网络。新闻末尾提到,5G网络仍在测试阶段,这意味着5G网络现在还不够稳定,无法在月球表面上运营。由此可知,科学家们选择4G网络是因为它比较稳定,故答案为A(它是稳定的)。B项(它是耐用的)、C项(它是便宜的)和D项(它是复杂的)均与新闻内容不符,故排除。
