The world’s biggest Internet search engine, Google, has proven once again to be King of the Web. Users can download “Google Wi-Fi” software and then enjoy free Wi-Fi service available in some US cities since last Tuesday.
Wi-Fi is short for “Wireless Fidelity”(无线上网). It allows laptop computers and personal digital assistants to the Internet at high speed by radio signal.
A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points. The place covered by one or several access points is called a hotspot. Google has already set up two “hotspots” in the US city of San Francisco which provide a free Wi-Fi service.
The Wi-Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks.
Wi-Fi is still limited to a few cities, where there are “hotspots”. But its capability(容量)of sending information has already done better than that of the mobile phone network, even that of 3G(Third Generation Telecommunication Technology). Some scientists have started to call Wi-Fi 4G.
In addition to a high speed Internet connection, Wi-Fi has other advantages compared to mobile phones. Wi-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don’t need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.

题目分析：这篇文章讲的是谷歌推出了免费的无线网络的服务，文章介绍连接无线网络的要求和和手机无线网络相比有什么优势。
小题1:推理题：从第三段的句子：A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points. The place covered by one or several access points is called a hotspot. 和第五段的句子：Wi-Fi is still limited to a few cities, where there are “hotspots”可知有hotspot的城市可以连接无线网，也就是如果没有hotspot就不能连接无线网，选D
