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。

unit3 Inventors and inventionsⅠ.阅读理解AToday, bicycles are elegantly simple machines that are common around the world. Many people ride bicycles for recreation, whereas others use them as a means of transportation. The first bicycle was invented in Germany in 1818. Because it was made of wood, it wasn’t very strong nor did it have pedals (脚踏板). Riders moved it by pushing their feet against the ground.In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, invented a much better bicycle. Macmillan’s machine had iron-covered wheels to keep them from getting worn down. He also used foot-operated levers, similar to pedals, so his bicycle could be ridden at a quick pace. It didn’t look much like the modern bicycle, though, because its back wheel was substantially larger than its front wheel. Although Macmillan’s bicycles could be ridden easily, they were never produced in large numbers.In 1861, Frenchman Pierre Michaux and his brother Ernest invented a bicycle with an improved pedal mechanism. They called their bicycle a VELOCIPEDE, but most people called it a “bone shaker” because of the effect of the wood and iron frame. Despite the impolite nickname, the VELOCIPEDE was a hit. After a few years, the Michaux family was making hundreds of the machines annually, mostly for fun-seeking young people.Ten years later, James Starley, an English inventor, made several innovations that revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient，and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top-heavy, and ridden mostly for entertainment.It wasn’t until 1874 that the first truly modern bicycle appeared on the scene. Invented by another Englishman, H. J. Lawson, the safety bicycle would look familiar to today’s cyclists. The safety bicycle had equal-sized wheels, which made it easier to ride. Lawson also attached a chain to the pedals to drive the back wheel. By 1893, the safety bicycle had been further improved with air-filled rubber tires, a diamond-shaped frame, and easy braking. With the improvements provided by Lawson; bicycles became extremely popular and useful for transportation. Today, they are built, used, and enjoyed all over the world.1．This passage was most likely written in order to ________.A．compare bicycles used for different purposesB．describe the problems early bicycle makers experiencedC．persuade readers to use bicycles for transportationD．tell readers about the early history of the bicycle解析：选D推理判断题。
