【題目】閱讀下面短文，從短文后各題所給的四個選項（A、B、C和D）中，選出可以填入空白處的最佳選項。
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，此處指的是人們對于Wi-Fi這個術(shù)語存在著一種普遍的(common)誤解。（2）根據(jù)上句句意，人們普遍認為Wi-Fi代表“無線保真度”，但是事實上并非如此。它只不過(simply)是使用802.11標準的一個注冊了商標的一種說法而已。simply相當于only，表示“只不過；僅僅”。
（3）根據(jù)句意，802.11標準是由IEEE這個機構(gòu)首先提出(develop)出來的。
（4）根據(jù)下半句可以推知，802.11標準使電腦可以通過無線電的方式而不是電線(wire)進行連接。
（5）根據(jù)句意，這個標準主要(largely)是由“Wi-Fi Alliance”這個商業(yè)團體進行宣傳的。
（6）根據(jù)句意，正是Wi-Fi Alliance這個商業(yè)團體率先進行了這項技術(shù)(technology)，也即Wi-Fi技術(shù)的商業(yè)化。
（7）根據(jù)生活常識，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)設一個“熱點”。B，D選項均為不可數(shù)名詞，不能用不定冠詞a修飾。A選項(標準)明顯不合題意。
（8）根據(jù)生活常識，用無線路由器或其它類似的設備可以創(chuàng)設一個“熱點”或一個區(qū)域，在這個區(qū)域中，使用適當?shù)脑O備就可以以無線的方式連接到一個網(wǎng)絡上或登陸互聯(lián)網(wǎng)gain Internet access相當于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(相當于a modem)的后置定語，表示“一個被用作一種高速連接手段的調(diào)制解調(diào)器”，one(a modem)與use之間為被動關(guān)系,故應該用use的被動形式來作后置定語。
（11）任何處在無線接入點(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，信號放大器可以擴大(extend)無線網(wǎng)絡覆蓋的范圍。
（14）根據(jù)與之并列的“closed”可以推知，Wi-Fi網(wǎng)絡既可以是開放的，也可以是封閉的。
（15）根據(jù)生活經(jīng)驗，封閉的無線網(wǎng)絡往往需要密碼(password)才能進入。
（16）根據(jù)上文提示A person can…to create a “hotspot”結(jié)合生活經(jīng)驗可以推知，通過某種設備使之覆蓋無線接入點的一個區(qū)域常常被稱作一個無線“熱點(hotspot)”。
（17）根據(jù)生活經(jīng)驗，任何人只要攜帶包含(include)適當?shù)墓δ艿脑O備都可以在熱點區(qū)域內(nèi)連接至網(wǎng)絡。
（18）根據(jù)生活常識以及下半句的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，公司的員工常常會被提供(provide)免費的無線互聯(lián)網(wǎng)接入服務。
（20）生活經(jīng)驗，咖啡店或類似的一些地方常常會將無線Wi-Fi接入互聯(lián)網(wǎng)作為一項免費的服務(service)提供給顧客。
