Wi-Fi is a wireless networking technology used across the globe. A 1 misunderstanding is that the term Wi-Fi is short for “wireless fidelity(保真度)”. However, this is not the case. Wi-Fi is 2 a trademarked phrase that uses the 802.11 standard, which was 3 by the Institute of Electrical and Electronics Engineers (IEEE). That is to say, instead of using 4, your computer is connected to the internet or other computers by radio.
This standard was 5 promoted by the Wi-Fi Alliance, a trade group that pioneered commercialization of the 6. A person or business can use a wireless router( 路由器) or a similar 7 to create a “hotspot” or an area in which proper devices can connect wirelessly to a network or 8 Internet access. This router is usually connected to the Internet by 9 of a modem, often one 10 as a high-speed connection. Any user within about 200 feet of the 11 point can then connect to the Internet, 12 for good transfer rates, distances of 100 feet or less are often suggested. Salespersons also sell signal boosters(放大器)that 13 the range of a wireless network.
Wi-Fi networks can either be 14 or closed, in which case a 15 is needed. An area blanketed in wireless access through a device is often called a “wireless 16.” Anyone with a device that 17 proper functionality can connect to this network while in the hotspot. Through this connection, a 18 network can be accessed or Internet connectivity can be achieved. This allows people within the hotspot to connect to the Internet via the router and modem, often 19 for employees at a business or as a free 20 at coffee shops and similar locations.

【解析】(1)根据下一句However,this is not the case可以推知,此处指的是人们对于Wi-Fi这个术语存在着一种普遍的(common)误解。(2)根据上句句意,人们普遍认为Wi-Fi代表“无线保真度”,但是事实上并非如此。它只不过(simply)是使用802.11标准的一个注册了商标的一种说法而已。simply相当于only,表示“只不过;仅仅”。
(3)根据句意,802.11标准是由IEEE这个机构首先提出(develop)出来的。
(4)根据下半句可以推知,802.11标准使电脑可以通过无线电的方式而不是电线(wire)进行连接。
(5)根据句意,这个标准主要(largely)是由“Wi-Fi Alliance”这个商业团体进行宣传的。
(6)根据句意,正是Wi-Fi Alliance这个商业团体率先进行了这项技术(technology),也即Wi-Fi技术的商业化。
(7)根据生活常识,路由器是一种工具。所以此处指可以利用路由器或相似的工具(device)来创设一个“热点”。B,D选项均为不可数名词,不能用不定冠词a修饰。A选项(标准)明显不合题意。
(8)根据生活常识,用无线路由器或其它类似的设备可以创设一个“热点”或一个区域,在这个区域中,使用适当的设备就可以以无线的方式连接到一个网络上或登陆互联网gain Internet access相当于gain access to Internet,表示“接入互联网”。
(9)by means of为固定搭配,表示“通过……”。
(10)根据句意以及语法,此处为one(相当于a modem)的后置定语,表示“一个被用作一种高速连接手段的调制解调器”,one(a modem)与use之间为被动关系,故应该用use的被动形式来作后置定语。
(11)任何处在无线接入点(access point)200英尺范围内的用户都可以连接至互联网。
(12)结合上半句,此处表示,虽然(though)在一百英尺以内可以获得最佳的传输速率,但是任何处在无线接入点200英尺范围内的用户都可以连接至互联网。
(13)根据生活经验,信号放大器可以扩大(extend)无线网络覆盖的范围。
(14)根据与之并列的“closed”可以推知,Wi-Fi网络既可以是开放的,也可以是封闭的。
(15)根据生活经验,封闭的无线网络往往需要密码(password)才能进入。
(16)根据上文提示A person can…to create a “hotspot”结合生活经验可以推知,通过某种设备使之覆盖无线接入点的一个区域常常被称作一个无线“热点(hotspot)”。
(17)根据生活经验,任何人只要携带包含(include)适当的功能的设备都可以在热点区域内连接至网络。
(18)根据生活常识以及下半句的or Internet connectivity可以推知,通过上述的连接方式可以接入局域网(local network)或互联网。
(19)根据生活经验,公司的员工常常会被提供(provide)免费的无线互联网接入服务。
(20)生活经验,咖啡店或类似的一些地方常常会将无线Wi-Fi接入互联网作为一项免费的服务(service)提供给顾客。
