　Unit 3　Tomorrows world 【美文阅读】 手提包是日常生活中很常见的物品，尤其是女士，你想拥有一个能充电的手提包吗？一起来看看吧！ 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 come out.The handbag，which is the brainchild of mechanical engineering student Joe Hynek，has already been well-received by eco-conscious 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(电路)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 competition 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 fully-charged 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. 【诱思导学】 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.　②The telegraph and telephone were the rapid forms of communication.　③Less than 50% of the population were city dwelling.　④There were
