Question

    One after another, telecommunications giants (通信巨头) have announced their latest fifth generation (5G) products. They have also claimed that 5G technology would be used on a massive scale by 2020. Yet, when reporting about 5G, many domestic media outlets have described it as a “much faster” technology than 4G without mentioning any of its other advantages. As a result, the common public view about 5G is that they could “download a high-density movie within one second”. Beyond that, most people know nothing about 5G.

Actually, 5G technology has many more advantages than 4G apart from speed. According to the criteria of 3GPP, an international standardization organization, 5G technology can be used for at least three purposes—for connecting everything, reliability of connections, and eliminating delays.

“Connecting everything” is an appropriate slogan for 5G technology, without which the Internet of things would be impossible. 5G would enable one server to connect to multiple terminals (终端) and thus establish high-speed coordination among them, and help the chips inside the terminals to timely react to meet people’s needs. Take for example, autonomous vehicles, which are mature technology products. Self-driving cars combine a variety of sensors, such as radar, computer vision, and GPS to identify navigation paths and obstacles. 5G technology will link all the elements of a transportation system, such as traffic lights, cameras and, of course, cars to establish perfect coordination so they can avoid obstacles and move on navigation paths, which will help strengthen self-driving technology.

Reliability of connections is another essential characteristic of 5G technology, whose use can be extended to other fields where high safety standards are required. For instance, in certain surgeries, surgeons insert nano-robots inside a patient’s body and have to maintain constant control over the robots to ensure they perform their functions and do not cause any harm to the patient. This is an technology can be of great help, as it can establish reliable and continuous connections between the monitor and the nano-robots.

【解析】

这是一篇说明文。文章主要介绍除了高速，5G技术还有连接一切、连接可靠性以及消除延迟等特点。

1.推理判断题。由第二段的第二句“According to the criteria of 3GPP, an international standardization organization, 5G technology can be used for at least three purposes—for connecting everything, reliability of connections, and eliminating delays.”，第三段的第一句““Connecting everything” is an appropriate slogan for 5G technology, without which the Internet of things would be impossible.”以及第四段的第一句“Reliability of connections is another essential characteristic of 5G technology, whose use can be extended to other fields where high safety standards are required.”可知，根据3GPP一个国际标准化组织的标准，5G技术能够在至少3个方面使用，分别时连接一切，连接的可靠性以及消除延迟。连接一切对于5G技术来说是一个合适的口号，没有这个特征因特网的所有事情都将变成不可能。连接可靠性是5G技术的另外一个基本特征，这一技术的使用可以延申到要求高安全标准的其他领域。由此可见，作者接下来可能会讨论的是5G技术的消除延迟这个特征。结合选项可知，选项A正确。

2.推理判断题。由第三段第二句“5G would enable one server to connect to multiple terminals (终端) and thus establish high-speed coordination among them, and help the chips inside the terminals to timely react to meet people’s needs.”可知，5G能让一个计算机服务器连接到多个终端，然后在它们之中建立告诉协调，并且帮助在终端里面的芯片能够及时做出反应满足人们的需求。结合选项可知，选项D表达的是“同时对所有成员进行网络测试”，符合5G的连接一切的特征，可以作为5G连接一切这个特征的具体举例。故选D。

3.细节理解题。由第四段的最后一句“This is an technology can be of great help, as it can establish reliable and continuous connections between the monitor and the nano-robots.”可知，这是一项非常有帮助的技术，因为它能在监控器和纳米机器人之间建立可靠而且持续的连接。由此可知，5G技术能够在高安全标准的领域使用，是因为它能提供可靠而且持续的服务。结合选项可知，选项B正确。

4.主旨大意题。由全文内容可知，第二段的第一句“Actually, 5G technology has many more advantages than 4G apart from speed.”，第三段的第一句““Connecting everything” is an appropriate slogan for 5G technology, without which the Internet of things would be impossible.”以及第四段的第一句“Reliability of connections is another essential characteristic of 5G technology, whose use can be extended to other fields where high safety standards are required.”可知，实际上，除了速度之外，5G技术比4G有更多的优势。连接一切对于5G技术来说是一个合适的口号，没有这个特征因特网的所有事情都将变成不可能。连接可靠性是5G技术的另外一个基本特征，这一技术的使用可以延申到要求高安全标准的其他领域。由此可见，全文主要是在讲述5G技术的特点不仅仅只是高速。结合选项可知，选项A正确。
