Passage Three
| There’s a great story about an old Finnish woman who, without quite realizing it, was using her cell-phone to access the Internet and track her city’s public transit system. When asked why she used the wireless Internet so frequently, she replied, "What are you talking about I don’t know anything about this wireless Internet stuff, I just know the bus is here." Regardless of whether you want to admit it, a lot of us are like that old Finnish woman. When it comes to new mobile applications, many of us do not realize the capability and power that we hold, literally, in our hands. What we’re looking at today is the mobile Internet in its infancy. Now that using the Inter- net from home or work has saturated much of society, the next logical step is to be able to use the Net when you’re away from your desktop or laptop. Speech recognition is one way to do this, and there are a number of services, collectively called the "voice Web", that will make this possible. All you do is use a phone or wireless device to call a phone number, and speak commands to an intuitive system. It will then give you the information you’re seeking, using either a synthesized voice or an audio file. In the United States and Europe, the hot technology for wireless devices is called WAP (Wireless Application Protocol), which is being considered as the world standard．WAP is supported by major phone companies including Nokia, Motorola and Ericsson, and is simply a means of transmitting information, much like HTML is a means of communicating on the Internet. Currently, wireless Internet connections may give you news, sports scores, stock quotes, and the weather if you’re lucky. But if you’ve ever used this technology, you know it’s slow, costly and doesn’t seem worth the time and effort, if it works at all. "The mobile Internet was never designed to take over surfing the Web from a computer," explains Cherie Gary, spokes woman at Nokia. All of this technology points to easier living. Perhaps you’ll need to find a restaurant for an occasional business meeting. You’ll press a button on your mobile phone, and access the Internet to pull up a list of great restaurants in your immediate area．You’ll hit another button, say a few words into tile handset and you’ve got a reservation for four. |
We can infer from the text that mobile Internet is different from the previous Internet in that mobile Internet______.
A．can be accessed by desktop
B．has no need of wire appliance
C．can be used to book the table for the user
D．has Speech recognition system
答案
参考答案：B
解析：推断题。文章第三段指出；“the next logical step is to beable to use the Net when you’re away from your desktop or laptop(下一个合理的举措就是在离开台式电脑或笔记本电脑时还可以访问因特网)”，第四段开头又介绍说：“the hot technology for wireless devices is called WAP(无线设备的热门技术叫‘无线应用协议’)”，由此可以推断出mobile Internet是指不需要有线设备就可以上网，这正是B项的内容。A项的内容是Internet的特征；C、D两项与题干无关。
