Question

【题目】 One of the biggest enemies of smartphone batteries is the phones ’ screens. The screens keep getting bigger, and they need to keep bright for outdoor use. 【1】 But, a new OLED technology can increase brightness and energy efficiency ( 效率). The technology is being developed by a team at the Imperial College London. They’re using a special development process to produce OLEDs that give off polarized light (偏振光).

So, what's that all meaning? Screens often include filters (滤光器) to help reduce unpleasant bright light from outside. 【2】 However, they also can prevent lots of the light from the screen itself. Any light that doesn’t make it to your eyes is basically wasted energy. By creating OLEDs that send out polarized light, the team can get the light from the OLEDs to pass through a polarized filter while light from outside will still get filtered by it.

For now, the technology doesn’t mean much for phones we have in our hands. Since it's still being researched, it's not likely to find its way for upcoming phones very soon. 【3】

When it does, it would result in brighter screens and improved energy efficiency. Screens would not use the same amount of energy to produce bright light because none of it would be filtered out. 【4】

And, that would mean much longer-lasting batteries for smartphones.

【5】 For example, smartwatches don't pack large batteries, so any efficiency improvement would have a strong benefit.

A.That means they will use more energy.

B.Plenty of phones already get a full day of life.

C.This technology can be used in other areas as well.

D.But it would finally be applied to consumers’ phones.

E.It can give OLED screens a huge step forward in competition.

F.The new technology can almost double the efficiency of screens.

G.These make it easier to see the light coming from your phone's screen.

Answer 1

【答案】

【1】G

【2】D

【3】C

【4】F

【5】E

【解析】

这是一篇说明文。文章介绍一种新的OLED技术可以提高亮度和能源效率。这项技术是由伦敦帝国理工学院的一个团队开发的。他们使用一种特殊的开发过程来生产能发出偏振光的OLED。

【1】根据上文提示“屏幕越来越大，在户外使用时需要保持明亮。”再根据下文提示“但是，一种新的OLED技术可以提高亮度和能源效率。”承接上下文，G项These make it easier to see the light coming from your phone's screen.（这些让你更容易看到来自手机屏幕的光线。）切题。故选G。

【2】根据上文提示“屏幕通常包括过滤器，以帮助减少来自外部的不愉快的强光。”再根据下文提示“然而，它们也可以阻止屏幕本身的大量光线。”承接上下文，D项But it would finally be applied to consumers’ phones.（但它最终将应用于消费者的手机。）切题。故选D。

【3】根据上文提示“因为它还在研究中，所以它不太可能很快就会出现在未来的手机中。”承接上文，C项This technology can be used in other areas as well.（这项技术也可以用于其他领域。）切题。故选C。

【4】根据上文提示“屏幕将不会使用相同数量的能量来产生明亮的光线，因为它不会被过滤掉。”承接上文，F项The new technology can almost double the efficiency of screens.（这项新技术几乎可以将屏幕的效率提高一倍。）切题。故选F。

【5】根据下文提示“例如,智能手表不装大电池,所以任何效率的提高都会有很大的好处。”承接下文，E项It can give OLED screens a huge step forward in competition.（它可以让OLED屏幕在竞争中向前迈出一大步。）切题。故选E。
