Ⅱ.阅读理解(考查热点:科技创新)
The trouble of having to charge(充电)your smartphone for hours a day could become a thing of the past.
British scientists have created a material that replaces the screen glass for phones, iPads and smartwatches, but uses no power,meaning they could be charged weekly. The discovery is important because more than 90 percent of a device's battery power illuminates(照明)the screen.
Technology firms have focused on improving battery life. But the British experts say dealing with the main power-using may give better results. Oxford University engineer Dr Peiman Hosseini, who invented the material, told The Sunday Telegraph,“You have to charge smartwatches every night. But if you had smart glass, you could recharge it just once a week.”
The invention uses electrical pulses to create displays that require no power and can be viewed even in direct sunlight. Dr Hosseini's company, Bodle Technologies, hopes to have a prototype(样机)in a year.
Battery life is seen as a major obstruction for modern computing and technology. While the power of technology and lifestyle gadgets(小器件)has improved rapidly in recent years, batteries have not kept pace. The success of smartwatches, including Apple's version, is thought to depend on solving this problem because few users are willing to charge a watch every day.
Gadget firms are also desperate to solve the problem.
Apple, for example, is investigating using fuel cells to power its phones and laptops, and this year has gained a patent for a system that it claimed could power its gadget for weeks.
In 2012 US energy secretary Steven Chu called for a big push to improve batteries, challenging scientists to produce a battery with five times the capacity within five years.
Aside from mobile gadgets, improving battery technology is seen as being key to the success of electric cars, which currently have a limited journey before they must stop to be recharged.
1.Who invented the new material?
A.Energy secretary. B.Oxford University engineer.
C.Technology firms. D.Apple Corps.
2.What can we know about the invention?
A.It has gained a patent. B.It is popular with customers.
C.It is a kind of glass. D.It uses power to charge the phones.
3.The author uses the example of Apple in Paragraph 7 to show .
A.what the key to success isB.why Apple products are popular
C.how often batteries must be recharged
D.how gadget firms are making efforts to improve batteries
4.What can be inferred from the passage?
A.90% of batteries will be replaced with smart glass.
B.It is likely that mobile phones will be recharged once a week.
C.Scientists are focusing on increasing the number of batteries.
D.Many users are willing to pay more for watches of Apple version.
II 1.B 细节题。根据第3段中的“Oxford University engineer Dr Peiman Hosseini, who invented the material, told The Sunday Telegraph:‘You have to charge smartwatches every night. But if you had smart glass, you could recharge it just once a week.’”可知,牛津大学工程师Dr Peiman Hosseini发明了这种材料。
2.C 细节题。根据第3段中“But if you had smart glass, you could recharge it just once a week.”可知,这是一种智能屏幕玻璃。
3.D 推断题。根据第7段可知,以Apple为例主要是为了说明很多公司在为其手机和笔记本电脑配备燃料电池。
4.B 推断题。英国科学家发明了一种材料,它可以替代手机、平板电脑和智能手表的现采用的屏幕玻璃,因为该材料不耗电,所以意味着装有这种屏幕的手机每周充一次电将很可能实现。
