13.You never see him,but they're with you every time you fly.They record where you are going,how fast you're traveling and whether everything on your airplane is functioning normally.Their ability to withstand almost any disaster makes them seem like something out of a comic book.They're known as the black box.
When planes fall from the sky,as a Yemeni airliner did on its way to Comoros Islands in the India Ocean June 30,2009,the black box is the best bet for identifying what went wrong.So when a French submarine (潛水艇) detected the device's homing signal five days later,the discovery marked a huge step toward determining the cause of a tragedy in which 152passengers were killed.
In 1958,Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction.That was the first model for a black box,which became a requirement on all U.S.commercial flights by 1960.Early models often failed to withstand crashes,however,so in 1965the device was completely redesigned and moved to the rear of the plane-the area least subject to impact-from its original position in the landing wells (起落架艙).The same year,the Federal Aviation Authority required that the boxes,which were never actually black,be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes:a voice recorder,which tracks pilots'conversations,and a flight-data recorder,which monitors fuel levels,engine noises and other operating functions that help investigators reconstruct the aircraft's final moments.Placed in an insulated (隔絕的) case and surrounded by a quarter-inch-thick panels of stainless steel,the boxes can withstand massive force and temperatures up to 2,000℉.When submerged,they're also able to emit signals from depths of 20,000ft.Experts believe the boxes from Air France Flight 447,which crashed near Brazil on June 1,2009,are in water nearly that deep,but statistics say they're still likely to turn up.In the approximately 20deep-sea crashes over the past 30years,only one plane's black boxes were never recovered.

24.What information could be found from the black box on the Yemeni airliner?A
A.Data for analyzing the cause of the crash.
B.The total number of passengers on board.
C.The scene of the crash and extent of the damage.
D.Homing signals sent by the pilot before the crash.
25.Why was the black box redesigned in 1965?C
A.New materials became available by that time.
B.Too much space was needed for its installation.
C.The early models often got damaged in the crash.
D.The early models didn't provide the needed data.
26.Why did the Federal Aviation Authority require the black boxes be painted orange or yellowC?
A.To distinguish them from the colour of the plane.
B.To caution people to handle them with care.
C.To make them easily identifiable.
D.To conform to international standards.
27.What do we know about the black boxes from Air France Flight 447?A
A.There is still a good chance of their being recovered.
B.There is an urgent need for them to be reconstructed.
C.They have stopped sending homing signals.
D.They were destroyed somewhere near Brazil.

分析 本文主要講的是黑匣子.他們記錄了你要去哪里,你的旅行是否你的飛機(jī)上的一切運(yùn)作正常;幾乎能經(jīng)受住任何災(zāi)難,這就是黑匣子.當(dāng)飛機(jī)失事時(shí),黑匣子就是識(shí)別真相的有力證據(jù).1958,澳大利亞科學(xué)家戴維Warren研發(fā)了一個(gè)飛行記錄器,高度、速度、方位等基本信息.這是黑盒子的開端.現(xiàn)代飛機(jī)有兩個(gè)黑盒子:一個(gè)錄音機(jī),跟蹤飛行員的對(duì)話,和飛行數(shù)據(jù)記錄器,監(jiān)控燃料量,發(fā)動(dòng)機(jī)的噪聲和其他的操作功能,幫助研究人員重建了飛機(jī)的最后時(shí)刻.耐壓耐高溫.在過去的三十年的深海里,只有一架飛機(jī)的黑匣子沒有恢復(fù).

解答 ACCA
24.A 由第二段第1,2行When planes fall from the sky,as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30,2009,the black box is the best bet for identifying what went wrong.可知,這個(gè)黑匣子里面有很多的數(shù)據(jù)可供分析使用,故A正確.
25.C倒數(shù)第二段Early models often failed to withstand crashes,however,so in 1965 the device was completely redesigned…文中提到,早期的黑匣子經(jīng)常抗不住空難的破壞(failed to withstand crashes),因此在1965年,黑匣子重新設(shè)計(jì)(redesigned),所以答案為C.
26.C 根據(jù)painted orange or yellow to aid visibility."被刷成橙色或黃色來提高能見度.根據(jù)常識(shí),我們知道在飛機(jī)失事時(shí)要找到黑匣子,黑匣子就一定要顯眼,所以刷成橙色和黃色容易會(huì)被人發(fā)現(xiàn).故選C.
27.A最后一段Experts believe the boxes from Air France Flight 447,which crashed near Brazilon June 1,2009,are in water nearly that deep,but statistics say they're still likely to turn up.In the approximately 20 deep-sea crashes over the past 30 years,only one plane's black boxes were never recovered.文中提到,專家相信法航447號(hào)的黑匣子是在水下20000英尺的深度,接著指出,但是統(tǒng)計(jì)數(shù)據(jù)顯示他們?nèi)匀豢赡艹霈F(xiàn),即有可能被找到,接下來的具體統(tǒng)計(jì)數(shù)據(jù)也進(jìn)一步說明了這一點(diǎn),所以答案為A.

點(diǎn)評(píng) 本文主要講了"黑匣子"的一些相關(guān)事宜.對(duì)于推理題的考查較多,在解答這類問題時(shí)要求學(xué)生抓住題干文字信息,采用針對(duì)性方法進(jìn)行閱讀,根據(jù)詞義關(guān)系推斷具體細(xì)節(jié),結(jié)合上下文提供的語境和信息進(jìn)行概括和判斷.

3.Have you ever had a science class that you look forward to?It doesn't happen often.But when you have a teacher like Mrs.Field,it's more than a science class.It's a science class where learning is easy and fun.There is no getting down to a huge textbook or listening to a teacher about something you don't care about.
My experience with Mrs.Field didn't start with science class,but with her as my tutor.I was always a weak reader and wasn't getting any better.My parents told me I needed to be tutored.One day after school,I went into the library with my mom for my first tutoring time.I had no idea who was tutoring me.My mom practically had to drag me into the library.The first thing we did was to play a game to get to know each other and get rid of the awkwardness.We didn't even play a reading game.
We also went around the library and I got to pick out a book I wanted to read.She didn't make me read a boring textbook about something I didn't care about.I didn't even pick a book.I picked out a magazine about remote control cars.I thought to myself,how bad could it be?To my surprise,She told me even though I was reading a magazine,I was still reading.After the first magazine,she picked out a book she liked.I would read a chapter and then she would read a chapter to me,in this way I didn't have to read for long periods of time.
As I got better and faster at reading,I was able to read two chapters in the same amount of time,which used to take me to read one chapter.
Reading is one of the most important things in high school and college to be successful.If it were not for her,I would not be the reader I am today!

21.The writer tutored by Mrs.Field becauseD.

B.he found science fun but hard.
C.he was eager to learn science.
D.he lacked the skills of reading.

B.the writer was unwilling to be tutored
C.the writer felt awkward to read in the library

8.For eighty four days old Santiago had not caught a single fish.At first a young boy,Manolin,had shared his bad fortune,but after the fortieth luckless day the boy's father told his son to go in another boat.From that time on,Santiago worked alone.The boy loved the old fisherman and  always helped him with money and food.Usually,they would talk about the fish they had taken in luckier times or about American baseball after supper,while at night,alone in his cottage,Santiago dreamed of lions on the beaches of Africa,where he had gone on a sailing ship years before.He no longer dreamed of his dead wife.
    On the eighty-fifth day,Santiago set off to fish before dawn.Two of his baits (餌) were fresh tunas (金槍魚) the boy had given him.Then he set his lines which went straight down into deep dark water.
     As the sun rose he saw other boats in toward shore.A man of war bird showed him where dolphin were chasing some flying fish.This time Santiago saw tuna jumping in the sunlight.A small one took the hook on his line.Pulling the fish aboard,the old man thought it a good fortune.
    Toward noon a marlin,a common fish in the s ea,started eating the bait which was one hundred meters down.Gently the old man played the fish,a big one,as he knew from the weight on the line.At last he struck to settle the hook.The fish did not come out of the surface.Instead,it began to pull the boat to the northwest.The old man followed it. Although he was alone and no longer strong,he had his skill and knew many tricks. He waited patiently for the fish to be tired.
     It became cold after the sunset.Suddenly the marlin leaned,pulling Santiago forward on his face and cutting his cheek.By dawn his left hand was cramped (抽筋的).The fish had headed northward; there was no land in sight.Hungry,he cut pieces from the tuna and chewed them slowly.That morning the fish jumped.Seeing it leap,Santiago knew he had hooked the biggest marlin he had ever seen.Then the fish went down and turned toward the east.Santiago drank a little water from the bottle during the hot afternoon.Close to nightfall a dolphin took the small hook he had baited.He lifted it aboard,careful.After he had rested,he cut meat from the dolphin and kept also the two flying fish he found in its stomach.That night he slept.He awoke to feel the line running through his fingers as the fish jumped.Making the line loose slowly,he tried to tire the marlin.After the fish slowed its run,he washed his cut hands in sea water and ate one of the flying fish.At sunrise the marlin began to circle.Faint and dizzy,he worked to bring the big fish nearer with each turn.Almost exhausted,he finally drew his big fish alongside and drove in the harpoon (魚叉).The fish was two feet longer than the boat.No fish like it had ever been seen in Havana harbor.An hour later,he sighted the first shark,a fierce Mako,and it came in fast to chase after the dead marlin.The old man struck the shark with his harpoon.The Mako rolled and sank,carryin g the harpoon with it and leaving the marlin bloody.He knew the smell would spread.Watching,he saw two sharks closing in.He struck at one with his knife and watched it sliding down into deep water.He killed the other while it tore at the flesh of the marlin.When the third appeared,he thrust (刺) it with the knife.The other sharks came at sunset.At first he tried to beat them with the tiller (舵柄) from the boat,but his hands were bleeding and there were too many in the sea.In the darkness,as he steered (掌舵)toward the harbor of Havana,he heard them hitting the boat again and again.But the old man thought only of his steering and his great tiredness.He had gone out too far and the sharks had beaten him.He knew they would leave him nothing but the stripped skeleton of the big marlin.
     All lights were out when he sailed into the little harbor and beached his boat.He could just make out the white backbone and the upstanding tail of the fish.Once he fell under their weight and lay patiently until he could gather his strength to go on.In his cottage he fell on his bed and went to sleep.
65.The above story is most likely to be adapted fromB.
A.The Adventures Of Tom Sawyer                     
B.The Old Man And The Sea        
C.The Son Of The Sea

C.The boy was Santiago's adopted son.
D.The boy showed his great concerns to Santiago.

18.(CNN,April 21)-The Olympic torch has been lit in southern Greece,kicking off the countdown to Rio 2016.
The Games were first held there in 776BC and remained there for 12centuries.
Acting the role of the high priestess (女祭司),Greek actress Katerina Lechou lit the torch using a concave (凹形) mirror to focus the sun's rays,before placing it into a ceramic bowl.An olive branch was cut and a white dove released into the blue spring sky,both symbolizing peace.
The flaming torch,which has its own Twitter account,was handed to its first torchbearer,gold medal-winning Greek gymnast Eleftherios Petrounias,before beginning its six-day relay across the country.
Another of the runners will be a Syrian refugee (難民),who will carry the torch through the Eleonas refugee camp in central Athens-part of a conscious effort by the International Olympic Committee (IOC) to highlight the hardships of refugees around the world.
For the first time in history,a team of 12refugee athletes from multiple countries will be competing in this year's Games.They will march behind the Olympic flag at the opening ceremony in Rio.
After its sprint through Greece,the torch will travel to Brazil on April 27to begin a 95-day tour visiting 83cities,26state capitals and 500towns-reaching an estimated 90% of the population.
It is the first time the Games have been held in South America,but the torch-lighting ceremony comes during uncertain times for Brazil.President Dilma Roussef faces the possibility of being impeached as early as May after she broke budgetary laws.
Thomas Bach,President of the International Olympic Committee,said in his speech at the torch-lighting ceremony that this year's Games"will be a message of hope in troubled times".
"In these difficult days that Brazil is facing,the flame is a timeless reminder that we all are part of the same humanity,"he said."May today's lighting of the Olympic flame be another reminder to everyone to uphold the spirit of the Olympic Games and to build a better world through sport."
The torch's Brazilian tour will involve an estimated 12,000torchbearers before arriving at Rio's famous Maracana Stadium for the Games'Opening Ceremony on August 5.
58.Which of the following statements is NOT true according to the passage?B
A.A concave mirror can make fire by focusing the sun's rays.
B.The Olympic torch will have a relay of six days in Brazil.
C.The Olympic Games will bring hope to today's Brazil.
D.Brazil is the first South American country to hold the Games.
59.Why did the IOC choose a Syrian refugee to carry the torch?C
A.The Syrian refugee shows great concern for the 2016Rio Olympics.
B.Carrying the torch will bring the refugee great fame in the world.
C.The IOC aims to make people aware of the world refugee problem.
D.The Syrian refugee wants to compete with other top competitors.

During a presentation at the annual Cardiac Scientific Sessions 2014 meeting of the American Heart Association (AHA),researchers warned about the risk of allowing young children(42)Kto the energy drinks,which contain high amounts of caffeine(咖啡因) and other stimulants.
Researches  (43)Ehat the energy drinks are not intended for young children and are not safe for them to consume.Steven Lipshultz,M.D.,lead author of the study,is calling for a warning on all energy drink cans and bottles,warning parents of the risk of allowing children to drink them.
Researchers say it is difficult to know exactly how much caffeine is contained in each can or bottle of energy drinks,since they are often (44)A as dietary supplements (補(bǔ)充物),which allow the manufacturers to avoid FDA regulations.
Energy drink manufacturers have compared the amount of caffeine in their products to that in hot drinks sold in coffee houses,but their products are often packaged in very large sizes and they are not sold in (45)Fnvironments like coffee houses,which typically would not serve young children.Energy drinks are widely available in (46)I stores next to traditional soft drinks,typically packaged in very similar cans and using similar marketing techniques.
Some energy drinks in many of the popular lines can contain up to 400mg of caffeine per can.In comparison,a cup of coffee typically has around 100mg of caffeine.Caffeine poisoning can occur in adults at levels higher than 400mg a day; however,children under 12can (47)B  caffeine poisoning at only 2.5mg per 2.2pounds of body weight.
A study published in September (48)Jup the new findings,revealing energy drinks may cause serious heart problems.French researchers revealed the popular energy drinks may be linked to (49)C risk of irregular heartbeats and even sudden death.
The FDA is  (50)H investigating health concerns surrounding the drinks after numerous negative event reports have been made in recent years connecting energy drinks to severe injuries and deaths.

I had decided to return home earlier than planned so that my son and his girlfriend could go out.I called home with this happy news.But instead of hearing his cheerful,grateful voice on the other end of the line,all I heard was the sound of a telephone ringing.
It was,I should point out,after 10 p.m.,when the two younger children should have been in bed.a(chǎn)nd when the two older children should have been answering the phone."I'll give him a lesson,"I said.I decided they must be outside.Why they might be outside at 10:30 on a winter night I had no idea,but it was the only explanation I could come up with.

The following Saturday evening we were at my parents home,celebrating my birthday.My oldest son gave me the children's gifts.Mounted and framed were a series of lovely color photographs of my children,dressed in their best clothes,and wearing their most wonderful expressions.They are pictures to treasure a lifetime,all taken by the father of my son's girlfriend.
