[技能提升] Ⅰ.閱讀理解(導(dǎo)學(xué)號(hào)02516343) (2018·唐山模擬)A new method of delivering data, which uses the visible spectrum (光譜) rather than radio waves, has

8、been tested in a working office. Li-fi can deliver Internet access 100 times faster than traditional Wi-fi, offering speeds of up to 1 Gbps (gigabit per second). It requires a light source, such as a standard LED bulb, an Internet connection and a photo detector. It was tested this week using a Li

9、-fi-enabled light bulb to transmit data at the speed of 1 Gbps. Laboratory tests have shown theoretical speeds of up to 224 Gpbs. When tested in an office, it allowed workers to access the Internet and in an industrial space，where it provided a smart lighting solution. Chief executive Deepak Solank

10、i said that the technology could reach consumers “within three or four years”． The term Li-fi was first coined by Prof. Haas, who demonstrated the technology at a Ted conference in 2011. His talk, which has now been watched nearly two million times, showed an LED lamp streaming video. Prof

11、. Haas described a future when billions of light bulbs could become wireless hot spots. One of the big advantages of Li-fi is the fact that, unlike Wi-fi, it does not interfere with other radio signals, so could be used on aircraft and in other places where interference is an issue. However, the

12、 technology also has its drawbacks－most notably the fact that it cannot be used outdoors in direct sunlight, because that would interfere with its signal. Neither can the technology travel through walls so initial use is likely to be limited to some places. [語篇解讀]　本文是一篇說明文。本文主要是向讀者介紹了一種被稱作Li
