2019-2020年高中英語 Unit 3 Tomorrows world教案 牛津譯林版必修4 【美文閱讀】 手提包是日常生活中很常見的物品，尤其是女士，你想擁有一個(gè)能充電的手提包嗎？一起來看看吧！ After a day at the office，the bleeps of a flat phone battery would normally signal despair.But now women can charge their electronic gadgets on the move－using only their handbag.Nicknamed the Power Purse，the bag uses solar panels to absorb the suns rays and turn them directly into electricity. Simply plug in your mobile phone，camera or iPod and begin praying the sun will e out.The handbag，which is the brainchild of mechanical engineering student Joe Hynek，has already been wellreceived by ecoconscious fashion websites. Mr.Hynek,29，said，“It begins working every time the user steps outside.People are very excited because it expresses ecological and environmental themes in addition to the function provided of charging your phone and iPod.” The black rectangular bag—which needs two hours of full sunlight to charge a mobile phone battery－uses solar panels to change sunlight into electricity.Power is then transmitted to a circuit(電路)connected to two batteries hidden in the lining of the bag and to a USB port.Most small devices can be charged，including mobile phones，and cameras. Mr.Hynek，who designed the bag three years ago during a petition at Iowa State University in the U．S.， said it can be topped up from a sunny windowsill as well as in the open air. A fullycharged battery can last for up to a month.“The wires are all enclosed，”he said.“The shape of it is designed so it can sit on a windowsill and charge while youre at work.”Although materials can be costly，Mr.Hynek has kept the price down to $150.The handbag is due to go on sale online by the end of this year. 【誘思導(dǎo)學(xué)】 1．What was our life like in the past，for example 50 years ago？Please show some examples. 【答案】　①The train was the rapid form of daily transportation.?、赥he telegraph and telephone were the rapid forms of munication.　③Less than 50% of the population were city dwelling.?、躎here were as many as two to five daily newspapers. ⑤People wanted and needed their news information from written sources.　⑥The legal understanding of privacy，and civil and constitutional rights was different.　⑦There were no supermarkets or refrigerators.?、郥here were no credit cards. 2．What effects does technology have on our life? 【答案】　Technology has many good effects.It has made our world an easier place.There are clearly dangers and drawbacks.Every new technology has unwanted side effects.For instance，the Industrial Revolution，while reducing manual labor in the long run，had and still has many negative consequences，such as pollution.
