[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 been tested in a working office. Lifi can deliver Internet access 100 times faster than traditional Wifi, 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 Lifienabled 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 Solanki said that the technology could reach consumers “within three or four years”． The term Lifi 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. Haas described a future when billions of light bulbs could bee wireless hot spots. One of the big advantages of Lifi is the fact that, unlike Wifi, 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 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(yǔ)篇解讀]　本文是一篇說(shuō)明文。本文主要是向讀者介紹了一種被稱作Lifi的新的傳播數(shù)據(jù)的方式。 1．Which of the following will be the best title of this passage? A．The drawbacks of traditional Wifi B．The advantages of Lifi C．Lifi 100 times faster than Wifi D．Lifi and Wifi 解析：C　[主旨大意題。通讀全文內(nèi)容可判斷出，本文主要介紹了一種被稱作Lifi的新的傳播數(shù)據(jù)的方式，它的傳播速度比Wifi快一百倍。故選C。] 2．Which of the following statements is TRUE? A．Traditional Wifi can reach speeds of up to 1 Gbps. B．The new technology has been put into use by consumers. C．Deepak Solanki showed the new technology at a conference in 2011. D．Lifi cant be used without a light source, an Internet connection or a photo detector. 解析：D　[細(xì)節(jié)理解題。根據(jù)第二段中的“It requires a light source，such as a standard LED bulb，an Internet connection and a photo detector.”可知，D項(xiàng)所述內(nèi)容正確。故選D。] 3．This passage may be 　________　.

Among them 41 were told to “preload” with water，while 43 were told to control their water intake before eating. After 12 weeks，the participants instructed to “preload” with water lost 2.87 pounds more than those in the control group on average. In addition, the participants preloading with water before each of their three main meals every day lost 9.48 pounds over the 12 weeks. 　__4__　 Dr. Helen Parretti, a lecturer at the University of Birmingham，had this to say of the study: 　__5__　 Just drinking 500 ml of water, three times a day, before your main meals may help reduce your weight... and this could be an easy way for weight loss.
