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）根據(jù)下一句However，this is not the case可以推知，此處指的是人們對(duì)于Wi-Fi這個(gè)術(shù)語存在著一種普遍的(common)誤解。（2）根據(jù)上句句意，人們普遍認(rèn)為Wi-Fi代表“無線保真度”，但是事實(shí)上并非如此。它只不過(simply)是使用802.11標(biāo)準(zhǔn)的一個(gè)注冊(cè)了商標(biāo)的一種說法而已。simply相當(dāng)于only，表示“只不過；僅僅”。
（3）根據(jù)句意，802.11標(biāo)準(zhǔn)是由IEEE這個(gè)機(jī)構(gòu)首先提出(develop)出來的。
（4）根據(jù)下半句可以推知，802.11標(biāo)準(zhǔn)使電腦可以通過無線電的方式而不是電線(wire)進(jìn)行連接。
（5）根據(jù)句意，這個(gè)標(biāo)準(zhǔn)主要(largely)是由“Wi-Fi Alliance”這個(gè)商業(yè)團(tuán)體進(jìn)行宣傳的。
（6）根據(jù)句意，正是Wi-Fi Alliance這個(gè)商業(yè)團(tuán)體率先進(jìn)行了這項(xiàng)技術(shù)(technology)，也即Wi-Fi技術(shù)的商業(yè)化。
（7）根據(jù)生活常識(shí)，路由器是一種工具。所以此處指可以利用路由器或相似的工具(device)來創(chuàng)設(shè)一個(gè)“熱點(diǎn)”。B，D選項(xiàng)均為不可數(shù)名詞，不能用不定冠詞a修飾。A選項(xiàng)(標(biāo)準(zhǔn))明顯不合題意。
（8）根據(jù)生活常識(shí)，用無線路由器或其它類似的設(shè)備可以創(chuàng)設(shè)一個(gè)“熱點(diǎn)”或一個(gè)區(qū)域，在這個(gè)區(qū)域中，使用適當(dāng)?shù)脑O(shè)備就可以以無線的方式連接到一個(gè)網(wǎng)絡(luò)上或登陸互聯(lián)網(wǎng)gain Internet access相當(dāng)于gain access to Internet，表示“接入互聯(lián)網(wǎng)”。
（9）by means of為固定搭配，表示“通過……”。
（10）根據(jù)句意以及語法，此處為one(相當(dāng)于a modem)的后置定語，表示“一個(gè)被用作一種高速連接手段的調(diào)制解調(diào)器”，one(a modem)與use之間為被動(dòng)關(guān)系,故應(yīng)該用use的被動(dòng)形式來作后置定語。
（11）任何處在無線接入點(diǎn)(access point)200英尺范圍內(nèi)的用戶都可以連接至互聯(lián)網(wǎng)。
（12）結(jié)合上半句，此處表示，雖然(though)在一百英尺以內(nèi)可以獲得最佳的傳輸速率，但是任何處在無線接入點(diǎn)200英尺范圍內(nèi)的用戶都可以連接至互聯(lián)網(wǎng)。
（13）根據(jù)生活經(jīng)驗(yàn)，信號(hào)放大器可以擴(kuò)大(extend)無線網(wǎng)絡(luò)覆蓋的范圍。
（14）根據(jù)與之并列的“closed”可以推知，Wi-Fi網(wǎng)絡(luò)既可以是開放的，也可以是封閉的。
（15）根據(jù)生活經(jīng)驗(yàn)，封閉的無線網(wǎng)絡(luò)往往需要密碼(password)才能進(jìn)入。
（16）根據(jù)上文提示A person can…to create a “hotspot”結(jié)合生活經(jīng)驗(yàn)可以推知，通過某種設(shè)備使之覆蓋無線接入點(diǎn)的一個(gè)區(qū)域常常被稱作一個(gè)無線“熱點(diǎn)(hotspot)”。
（17）根據(jù)生活經(jīng)驗(yàn)，任何人只要攜帶包含(include)適當(dāng)?shù)墓δ艿脑O(shè)備都可以在熱點(diǎn)區(qū)域內(nèi)連接至網(wǎng)絡(luò)。
（18）根據(jù)生活常識(shí)以及下半句的or Internet connectivity可以推知，通過上述的連接方式可以接入局域網(wǎng)(local network)或互聯(lián)網(wǎng)。
（19）根據(jù)生活經(jīng)驗(yàn)，公司的員工常常會(huì)被提供(provide)免費(fèi)的無線互聯(lián)網(wǎng)接入服務(wù)。
（20）生活經(jīng)驗(yàn)，咖啡店或類似的一些地方常常會(huì)將無線Wi-Fi接入互聯(lián)網(wǎng)作為一項(xiàng)免費(fèi)的服務(wù)(service)提供給顧客。
