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 (潜水艇) 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 (起落架舱).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 (隔绝的) 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 本文主要讲的是黑匣子.他们记录了你要去哪里,你的旅行是否你的飞机上的一切运作正常;几乎能经受住任何灾难,这就是黑匣子.当飞机失事时,黑匣子就是识别真相的有力证据.1958,澳大利亚科学家戴维Warren研发了一个飞行记录器,高度、速度、方位等基本信息.这是黑盒子的开端.现代飞机有两个黑盒子:一个录音机,跟踪飞行员的对话,和飞行数据记录器,监控燃料量,发动机的噪声和其他的操作功能,帮助研究人员重建了飞机的最后时刻.耐压耐高温.在过去的三十年的深海里,只有一架飞机的黑匣子没有恢复.

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,这个黑匣子里面有很多的数据可供分析使用,故A正确.
25.C倒数第二段Early models often failed to withstand crashes,however,so in 1965 the device was completely redesigned…文中提到,早期的黑匣子经常抗不住空难的破坏(failed to withstand crashes),因此在1965年,黑匣子重新设计(redesigned),所以答案为C.
26.C 根据painted orange or yellow to aid visibility."被刷成橙色或黄色来提高能见度.根据常识,我们知道在飞机失事时要找到黑匣子,黑匣子就一定要显眼,所以刷成橙色和黄色容易会被人发现.故选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,专家相信法航447号的黑匣子是在水下20000英尺的深度,接着指出,但是统计数据显示他们仍然可能出现,即有可能被找到,接下来的具体统计数据也进一步说明了这一点,所以答案为A.

点评 本文主要讲了"黑匣子"的一些相关事宜.对于推理题的考查较多,在解答这类问题时要求学生抓住题干文字信息,采用针对性方法进行阅读,根据词义关系推断具体细节,结合上下文提供的语境和信息进行概括和判断.

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!

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 (饵) were fresh tunas (金枪鱼) 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 (鱼叉).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.

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 (难民),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.

5.Amelia Earhart (1897-1937)was born in Kansas,USA,and moved to Chicago in 1914 when her father was fired from the Rock Island Railroad.After graduating from high school in 1915,she went to Canada where she worked as a nurse's helper.In 1919 she attended Columbia University but gave up after a year to join her parents in California.
    In 1920 Earhart went to her first air show and was attracted.She took flying lessons and bought her first plane,which she flew to a height of 14,000 feet in October 1922,a women's world record.In 1925 she moved to Boston and got a job as a social worker.During that time,she also wrote local newspaper columns (专栏) on flying.
    Earhart will be mainly remembered for being the first woman to fly solo (单独) non-stop across the Atlantic.On May 20,1932,she took off from New Brunswick,Canada.She wanted to fly to Paris,but poor weather conditions and mechanical
(机械的) problems forced her to land in Derry,Northern Ireland.
    It was certain that Earhart would attempt a round-the-world flight and she left Miami,USA on June 1,1937.Aft er stopping in South America,Africa,the Indian subcontinent and Southeast Asia,she arrived in New Guinea,an island in the southwest Pacific Ocean,on June 29.She left on July 27,but while she was crossing the Pacific,contact (联系) was lost.The US government spent  4 million looking for her,but she was never found.
    Earhart published two books about her flying experiences:20 H ours 40 Minutes and The Fun of It,but she went missing before her thi rd book was published.She was awarded the Distinguished Flying Cross by Congress and the Cross of Knight of the Legion of Honour by the French government.

Young children may face serious health risks from popular energy drinks,such as Monster,Red Bull and Rock Star,(41)G causing heart problems and other life-threatening conditions,according to the findings of new researches.
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 (补充物),which allow the manufacturers to avoid FDA regulations.

3.One evening I went out and left my 17-year-old son in charge of his 8-year-old brother and 4-year-old sister.On this occasion,the work was made less troublesome by the presence of his girl friend.I left with complete confidence that the older children would do a wonderful job of babysitting the younger children.Later,I discovered that complete confidence was the last thing I should have left home with.
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.and 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.
Finally,in desperation,I called his girlfriend's house.After what seemed like countless rings,his girlfriend answered."Yes,"she said brightly,"He's right here."
He came on the phone.I was not my usual calm,rational(理智的)self.After all,one of the rules of survival for modern parents is that you can't trust modern teenagers."Where are the children?"I said.He said they were with him.They had done nothing wrong.My son had taken the younger children over to his girlfriend's house just for ice cream and cake.This was too good to be believed.Well,it turns out that I shouldn't have believed it.It was only part of the truth.
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.
