20、2020广东省高三六校第一次联考)What does WiFi stand for?Long gone are the days of dialup and waiting for your turn to use the computer. Its easier than ever to connect to the Internet in the digital world today. 1 WiFi is a wireless network that uses radio frequency signals to connect to the Internet or send mess

21、ages between devices without wires. Everything from your phone and laptop to tablets and printers can use WiFi, thanks to these waves. 2 Two years later, a group of companies formed the Wireless Ethernet Compatibility Alliance (WECA, now the WiFi Alliance), a global nonprofit organization created to

22、 promote the new WiFi standard.None of that history explains what WiFi stands for, because the phrase doesnt stand for anything. WiFi is a trademarked term describing the device or technology based on the Institute of Electrical and Electronics Engineers (IEEE) wireless communication standard 802.11

23、, according to the WiFi Alliance. 3 So the WiFi Alliance hired the marketing company Interbrand to come up with a shorter name: WiFi, according to one of the founding Alliance members. 4 The rumor that it stands for “Wireless Fidelity (无线保真)” is thanks to the Alliance. Some members didnt understand

24、the branding or marketing for WiFi. They felt consumers would want an explanation for the name. So the Alliance agreed to include a tagline: The Standard for Wireless Fidelity. Thats why so many people assume WiFi stands for wireless fidelity, but the tagline came after the name. 5 Dont add to the c

25、onfusion and stop associating these phrases by learning the real meaning behind these acronyms (首字母缩略词)AThats a mouthful.BThis is mostly thanks to WiFi.CThe name caused a misconception about WiFi.DThere is some debate surrounding the question what WiFi stands for.EIn 1997, a committee of industry le

26、aders approved a common WiFi standard.FSeveral years ago, a common standard of WiFi was set up by several companies.GPlus, the Alliance removed the tag, although the confusion it brought still lives on today.篇章导读：本文是一篇说明文。在当今的数字世界，上网比之前更加容易，这主要感谢WiFi，本文介绍了什么是WiFi。1B根据第一段前两句可知，拨号上网的日子早已成为过去，如今和以往相比更容

27、易连接网络，且设空处下文紧接着介绍了WiFi的相关内容，由此可知，B项“这主要感谢WiFi”承上启下，符合语境。2E根据设空后一句可知，两年后，几个公司成立了无线以太网兼容性联盟，目的是推广新的WiFi标准。与新的标准相对应则是一般的、普通的标准，E项中的“a common WiFi standard”与设空后的“new WiFi standard”对应，再结合常识和语境可知答案选E项。3A根据前一句可知，根据WiFi联盟的说法，WiFi是一个商标术语，用来描述基于IEEE无线通信标准802.11的设备或技术，下文表明WiFi联盟聘请了营销公司Interbrand为它起了一个短一点的名字：Wi

28、Fi；由此可知，上文的那个名字又长又拗口。故A项符合语境。mouthful意为“又长又拗口的词(或短语)”。4D根据下文中的“The rumor that”和“Some members didnt understand”可推知，人们对于WiFi是什么这个问题还有一些争议，故选D。5G根据设空后一句可知，作者建议不要混淆两者；设空前两句又表述该联盟的标签带来了混淆。由此可知，G项“而且，虽然该联盟去除了这个标签，但它带来的困惑到现在仍然存在”符合语境。.概要写作阅读下面短文，根据其内容写一篇60词左右的内容概要。The Internet provides people with a large

29、quantity of information, but is so much information valuable for people, or does it cause problems to people? In my opinion, every coin has two sides. The advantages of the Internet information are much more than the disadvantages it brings to people.The Internet advocates freedom of information exc

30、hange and speech. This is an important part of a successful modern democratic (民主的) society. With a good many information sources, people have the opportunity to teach themselves. The knowledge that people master will allow them to make contributions to the development of the society. In the same wa

31、y, the ability to listen to different opinions will allow people to join in meaningful dialogues with others. This will make people more and more openminded and the society more and more tolerant (宽容的). The Internet, through the information on it, will bring together people of the same interests and

32、 the same concerns, and encourage them to work together. They will become active members of the society.However, critics (批评家) of free flow of information on the Internet are worried that incorrect or bad information will have a harmful influence on people. People will be addicted to it and act on i

33、t. This concern is very reasonable, because the Internet is anarchic (无政府主义的) in nature, and anyone that has a computer can create a website and post information on it. It is really quite hard to determine whether the information is correct or not. In fact，people can solve this problem by learning t

34、o evaluate information sources. For example, the website of a scientist at a major university is no doubt a much more reliable information source than the personal website of a junior student. 写前导读：本文是一篇议论文。文章探讨了互联网的优、缺点及相关使用建议。精彩范文There are more advantages of the Internet than the disadvantages tha

35、t it brings to people. (要点1) Freedom of information exchange and speech, which is advocated on the Internet, is an important part of a successful modern democratic society. (要点2) But critics are concerned about the harmful effects of incorrect or bad information on the Internet. (要点3) However, people can work out the problem by learning to make a judgement about information sources. (要点4)
