Unit 3 Inventors and inventions【美文阅读】Wireless charging for mobile phones by 2012近日，日本的富士通公司宣布，他们开发出了一套能为手机等便携式电子设备无线充电的系统。
Fujitsu，a Japanese technology company，has created a system capable of simultaneously(同时地) charging many portable electronic devices such as mobile phones，digital cameras and laptops without the need for cable(电缆)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 Communication Engineers conference.Claiming to be the world's 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 commercially sell products combining the new wireless charging system as early as 2012.Mobile phone users in Japan can currently charge their batteries using portable battery devicesavailable at most train stations and convenience stores－although phone companieswarn 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 company added，“We are also looking at applying the results of this work to fields other than portable electronics，including power transmission between circuit boards(电路板) or computer chips，and providing mobile charging systems for electric cars.”【诱思导学】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 2012.Period ⅠPreviewing(教师用书独具)●教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，为下一堂课对课文的全面理解起到一个铺垫作用。
