【題目】 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 (濾光器) 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.

【答案】

【1】G

【2】D

【3】C

【4】F

【5】E

【解析】

這是一篇說(shuō)明文。文章介紹一種新的OLED技術(shù)可以提高亮度和能源效率。這項(xiàng)技術(shù)是由倫敦帝國(guó)理工學(xué)院的一個(gè)團(tuán)隊(duì)開發(fā)的。他們使用一種特殊的開發(fā)過程來(lái)生產(chǎn)能發(fā)出偏振光的OLED。

【1】根據(jù)上文提示“屏幕越來(lái)越大，在戶外使用時(shí)需要保持明亮。”再根據(jù)下文提示“但是，一種新的OLED技術(shù)可以提高亮度和能源效率�！背薪由舷挛�，G項(xiàng)These make it easier to see the light coming from your phone's screen.（這些讓你更容易看到來(lái)自手機(jī)屏幕的光線。）切題。故選G。

【2】根據(jù)上文提示“屏幕通常包括過濾器，以幫助減少來(lái)自外部的不愉快的強(qiáng)光。”再根據(jù)下文提示“然而，它們也可以阻止屏幕本身的大量光線。”承接上下文，D項(xiàng)But it would finally be applied to consumers’ phones.（但它最終將應(yīng)用于消費(fèi)者的手機(jī)。）切題。故選D。

【3】根據(jù)上文提示“因?yàn)樗�在研究中，所以它不太可能很快就會(huì)出現(xiàn)在未來(lái)的手機(jī)中。”承接上文，C項(xiàng)This technology can be used in other areas as well.（這項(xiàng)技術(shù)也可以用于其他領(lǐng)域。）切題。故選C。

【4】根據(jù)上文提示“屏幕將不會(huì)使用相同數(shù)量的能量來(lái)產(chǎn)生明亮的光線，因?yàn)樗粫?huì)被過濾掉�！背薪由衔模�F項(xiàng)The new technology can almost double the efficiency of screens.（這項(xiàng)新技術(shù)幾乎可以將屏幕的效率提高一倍。）切題。故選F。

【5】根據(jù)下文提示“例如,智能手表不裝大電池,所以任何效率的提高都會(huì)有很大的好處�！背薪酉挛模�E項(xiàng)It can give OLED screens a huge step forward in competition.（它可以讓OLED屏幕在競(jìng)爭(zhēng)中向前邁出一大步。）切題。故選E。

【題目】 It was February and Danny Filippidis and his friends were skiing around. After a few days of fun and relaxation, their annual trip was coming to a close. Danny wanted to capture(捕捉) a few more memories of it to post online when they got home. The problem was, he’d left his cell phone in the car.

By the time Danny realized this, he and his friends were already halfway up Whiteface Mountain in Lake Placid. Not wanting to miss a moment, he told his friends to wait while he skied back down to fetch the phone. Danny was an adult and an experienced skier, so they had no reason to doubt his return.

However, it wasn’t until it began to get dark that his friends finally realized something may have gone wrong. They called the police, who began a ground search in no time. Before long, his family and friends came down to help as well. But Danny was nowhere to be found.

What the rescue teams didn’t know at the time was that, by the time the alarm went out, Danny wasn’t even in Lake Placid anymore. He’d taken a wrong turn on his way back to the car, falling down and becoming knocked out. It was dusk by the time he woke up, not knowing where he was.

Danny struggled his way to the road. He flagged down a truck in the hope of securing a ride off the mountain. The truck stopped and he climbed into the warm cab. After telling the trucker where he was going, he fell into a heavy sleep. When the trucker finally informed him that they had arrived, it had been midnight, when his family and friends were still searching the cold wilderness for any sign of him.

Danny often reflects on what might have happened if he hadn’t been found by that trucker. To this day, Danny Filippidis doesn’t know the trucker’s name. He doubts whether he could even point him out if he saw him on the street and the police have been unable to track the man down as well.

【1】Why did Danny ski back to fetch his phone?

A.To surf the Net.B.To avoid it being stolen.

C.To make a call.D.To shoot some photos.

【2】What happened to Danny on his way down the mountain?

A.He got stuck in a rock.B.He fell down the mountain.

C.He met with a snowstorm.D.He crashed into a truck.

【3】What can we learn from the last paragraph?

A.Danny was grateful to the trucker.B.Danny was extremely forgetful.

C.The authorities took no action at all.D.The trucker was hard to recognize.

【題目】I think people everywhere dream about having lots of money. I know I do. I would like to earn large amounts of money. You can win a large amount of money in the United States through lotteries. People pay money for tickets with numbers. If your combination of numbers is chosen, you will win a huge amount of money — often in the millions.

A few years ago, my friend Al won the lottery. It changed his life. He was not “born with a silver spoon in his mouth”. Instead, my friend was always short of money. And the money he did earn was chicken feed.

Sometimes Al even had to accept handouts (施舍物) from his friends. But do not get me wrong. My friend was always very careful with the money he spent. In fact, he was often a cheapskate. He did not like to spend money. The worst times were when he had no single penny left.

One day, Al scraped together a few dollars for a lottery ticket. He thought he would never gain lots of money unexpectedly. But his combination of numbers was chosen and he won the lottery. Al was so excited. The first thing he did was buy a costly new car — one thing that he normally would not buy. Then he started spending money on unnecessary things. It was like he had “money to burn”．

When we got together for a meal at a restaurant, Al paid every time. He would always tell me the money made him feel like a millionaire. But, Al spent too much money. Soon he was “down and out” again. He had spent his “bottom dollar” — his very last amount. He did not even save any of the money.

I admit I do feel sorry for my friend. He had enough money to “l(fā)ive like a king”. Instead, he was back to “l(fā)iving on a shoestring” — a very low budget. Some might say he was wise about small things, but not about important things.

【1】What does the author desire to do like others?

A. To combine the numbers perfectly.

B. To make a huge fortune.

C. To be chosen for selling lotteries.

D. To get in touch with millionaires.

【2】Before Al won the lottery ________.

A. he spent too much money buying chicken

B. he didn’t value the money he had earned

C. he had trouble feeding his family

D. he hated to give a hand to his friends

【3】What does the fourth paragraph imply?

A. Al always had good luck in life.

B. Al valued his money above his life.

C. Al had loved the expensive car probably.

D. Al pretended to have more money.

【4】When a person is “down and out”， ________.

A. he is as poor as a church mouse

B. he lives a life like other people

C. he has set aside all his money

D. he is looking forward to big success
