In the 19th century, the invention of the telegraph and the telephone forever changed how messages moved around the world. In the 20th century, radio, television, computers and the Internet further revolutionized the near-instantaneous processing and transmission of data.

【B1】 ___________.

Linking it all together? An absence of wires, a wireless age.

Every month, it seems, a new cell phone comes out that’s “smarter” than the last in its ability to gather and transmit a growing amount of data: voice, images, news and more.

Cell phones, or at least the technology behind them, have been around since the 1960s. By the 1980s, mobile phones had evolved but were still “giant, brick-shaped luxury items for geeks or the rich,” said Norm Rose, head of Travel Technology Consulting.

【B2】 ____________.

The Internet also played a large role in shaping the wireless world, changing not only how businesses worked but also how information was shared. Laptop computer and PDA users can now sit down and instantly sync (同步) up on the internet at tens of thousands of “hotpots” in homes, cafes and other high traffic areas nationwide.

【B3】 ____________.

“Everyone is going to be able to tap into this pervasive wireless world,” said Wade Roush, senior editor of Technology Review, pointing to rapidly improving technology and falling prices. “Wireless technologies are going to change the way we communicate with each other.”

Those connected with the wireless world say wireless technologies are in their infancy and may just be beginning a significant growth spurt. Telecommunications companies, meanwhile, are hyping (大肆宣传) a significant mobile network upgrade-dubbed 3G or “Third Generation”—that will let cell phones and other such devices transmit more data, and do it faster than ever before.

【B4】 ____________.

“Smartphones”—cell phones that gather and display information beyond simply sound—have garnered much of the buzz domestically. A new wave of better, faster phones will hit the United States only after 3G or other such networks become a reality, Rose said.

【B5】 ____________.

You will be able to go down to the store and buy almost any piece of consumer electronics, plug it into your wall, it’ll sense your Wi-Fi network and automatically configure itself. It’s going to be one of those technologies that weaves into all facets of our lives.

“We’ll start to think of computing as a natural part of our environment in the same way we might think about heating and air conditioning now,” Roush said, “It’s just always there.”

A. Wi-Fi (wireless-fidelity, 无线保真) is also developing, strong pace, at a steady in ways that its inventors never intended. Engineers are working to incorporate Wi-Fi into cell phones, PDAs and other such devices.

B. Soon, pundits predict, many more consumer electronics - from computers stereos to coffee makers-could electronically connect with one another, as well as with thermostats, watches and other digital devices.

C. Wi-Fi, Bluetooth and other wireless technologies work under the same general concept, the differentiating factors typically being the speed and distance a user can move from the base station and still maintain the connection.

D. Even with the tremendous technological improvements in cell phones—sending images, text messages and, of course, sound -such upgrades become moot (无实际意义的) if mobile users cannot always get a clear connection because of an imperfect network.

E. Experts say the 21st century will usher in a second Information Age in which these technologies, and their benefits, will be accessible anytime, anywhere.

F. “Think of the Internet, back in 1995-1996,” said Norm Rose. “Wireless and mobile technology is the next boom. When it takes off, it will be even more disruptive than the Internet.”

G. In the 1990s, cell phones and laptops became less bulky and expensive, new gadgets like personal digital assistants (PDAs) help people better manage their lives electronically, and a growing number of other devices—from kitchen appliances to televisions—began incorporating digital technology.

问答题 【B1】
【正确答案】E
【答案解析】文章第一段分别讲述了19世纪和20世纪传播信息的工具, 所以接下来一段应该是继续按照时间顺序讲述21世纪的相关情况, 所以选择E项, 专家声称21世纪将会开启第二次信息时代, 每个人将有机会在任何时间任何地点利用这些科技并享受其好处。
问答题 【B2】
【正确答案】G
【答案解析】本题前一段中指出到20世纪80年代时, 手机有所发展, 但仍然太巨大、 太贵, 所以接下来讲述在20世纪90年代时, 手机和平板电脑变得不那么笨重和昂贵了, 像个人热点助手的新工具帮助人们更好地利用电子管理生活, 例如厨房用具和电视的越来越多的其他设备开始采用数字科技。
问答题 【B3】
【正确答案】B
【答案解析】本题前一段中指出平板电脑和个人热点助手的用户能够在全国范围内 连上热点实现网络的同步,所以接下来专家预测很快更多的电子产品, 如电脑立体声系统及咖啡机, 能够与彼此进行电子连接, 以及同恒温控制器、 手表及其他电子设备连接。
问答题 【B4】
【正确答案】F
【答案解析】本题前一段中指出连接了无线的人们说无线技术仍然处于萌芽期, 将会开始巨大的发展冲刺, 所以接下来话题应该是继续围绕无线网络, 因此选择F项, 罗斯说, 想想1995-1996年的因特网, 无线和移动技术是下一次繁荣期, 当它起飞时, 将会产生比因特网更大的影响。
问答题 【B5】
【正确答案】A
【答案解析】本题后一段中指出你能够去一家商店, 买任何价位的电子产品, 它能够检测无线保真网络并自动连接, 所以此处应该先介绍一下无线保真, 即选择A项, 无线保真正在以稳定而快速的方式发展, 这是其创造者从未想过的, 工程师们正在工作以将无线保真加入到手机、 个人热点及其他设备中去。
