2019-2020年高中英語 Unit 3 Inventors and inventions教案 新人教版選修8 【美文閱讀】　 Wireless charging for mobile phones by xx 近日，日本的富士通公司宣布，他們開發(fā)出了一套能為手機等便攜式電子設(shè)備無線充電的系統(tǒng)。 Fujitsu，a Japanese technology pany，has created a system capable of simultaneously(同時地) charging many portable electronic devices such as mobile phones，digital cameras and laptops without the need for cable(電纜)connections. Electric car users may also eventually be able to charge their vehicles wirelessly using the same technology according to Fujitsu，which displayed a model system at an Institute of Electronics，Information and munication Engineers conference. Claiming to be the worlds first of its kind，the technology works on the basis of the transmission of electricity using magnetic(磁的)fields between the charger and the electronic device. The system makes it possible to charge wirelessly at distances of up to several meters，and Fujitsu aims to provide public “charging spots” on the streets in order to provide easy charging day and night. Scientists at Fujitsu Laboratories are planning to mercially sell products bining the new wireless charging system as early as xx. Mobile phone users in Japan can currently charge their batteries using portable battery devicesavailable at most train stations and convenience stores－although phone panies warn this can damage the phones. The new system invented by Fujitsu，however，is much more advanced and represents the next generation of portable recharging systems using flexible wireless technology.The pany added，“We are also looking at applying the results of this work to fields other than portable electronics，including power transmission between circuit boards(電路板) or puter chips，and providing mobile charging systems for electric cars.” 【誘思導(dǎo)學(xué)】　 1．How does the wireless charging technology work? ______________________________________________ ______________________________________________ 【答案】　It works on the basis of the transmission of electricity using magnetic fields between the charger and the electronic device. 2．When can consumers probably buy products using the new wireless charging system? ______________________________________________ 【答案】　As early as xx.
