Things Your Pilot Won't Tell YouYou may not be getting the airline you paid for.You may go to an airline website and buy a ticket, and get onto an airplane that has a similar name painted on it, but half the time, you're really on a regional airline.The regionals aren't held to the same safety standards as the majors: their pilots aren't required to have as much training and experience, and the public doesn't know that.﹣Captain at a major airlineIf you're a nervous flier, book a morning flight.The heating of the ground later causes bumpier (颠簸的) air, and it's much more likely to thunderstorm in the afternoon.﹣Jerry Johnson, pilot, Los AngelesThe smoothest place to sit is often over or near the wing.The bumpiest place to sit is in the back.If you're in the middle, you don't move as much.﹣Patrick Smith, pilot, and author of Cockpit ConfidentialSit in the front if you want fresher air.The general flow of air in any airplane is from front to back.So if you're really concerned about breathing the freshest possible air or not getting too hot, sit as close to the front as you can.Planes are generally warmest in the back.﹣Tech pilot at a regional airline, TexasYou never know where the safest seat is.There is no safest place to sit.In one accident, the people in the back are dead; in the next, it's the people up front.﹣John Nance, aviation safety analyst and retired airline captain, SeattleI've been struck by lightning twice.Most pilots have experienced it.Airplanes are built to take it.You hear a big boom and see a big flash and that's it.You're not going to fall out of the sky.﹣Charlotte, pilot for a regional earner, .North CarolinaPeople don't understand why they can't use their cell phones.Well, what can happen is 12 people will decide to call someone just before landing, and I can get a false reading on my instruments saying that we are higher than we really are.﹣Jim Tilmon, retired American Airlines pilot, Phoenix(1)What can we learn from the captain at a major airline?________A It is convenient to get your airline tickets from the website.B Half of all airlines have a similar name.C The major airlines are usually safer than regionalairlines.

All you have is what you bring with youI've always felt a need to be prepared for whatever situation I've found myself in.My mother once took me to a store when I was seven years old.She and I got to the checkout counter, and she realized she had forgotten a couple of things on her shopping list.She left me with the cart and ran off to get what she needed."I'll be right back."she said.She was gone just a few minutes, but in that time, I had loaded all the things on the belt and everything was rung up.I was left staring at the cashier, who was staling at me."Do you have money for me, son? "she said."I'll need to be paid."﹣I didn't realize she was just trying to amuse herself.So I stood there, ashamed and embarrassed.By the time my mom returned, I was angry."You left me here with no money!This lady asked me for the money, and I had nothing to give her I"Now that I'm an adult, you'll never catch me with less than $200 in my wallet.I want to be prepared in case I need it.I've always admired people who are over﹣prepared.In college, I had a classmate named Norman.One day he was giving a presentation on an overhead projector and in the middle of his talk, the light bulb (灯泡) on the projector blew out.We would have to wait ten minutes until someone found a new'projector."It's Okay."he announced."There's nothing to worry about."We watched him walk over to his bag and pull something out.He had brought along a spare bulb for the Overhead projector.Who could even think of that?I often told my students, "When you go into the wilderness, the only thing you can depend on is what you take with you."And essentially, the wilderness is anywhere but your home or office.So take money.Pack a light bulb.Be prepared.(1)Why did the cashier ask a seven﹣year﹣old boy to pay for the purchases'?________A The boy was shopping by himself.B The boy's mother asked her to doso. C The cashier was playing a joke on him. D The boy's mother was away for something else..(2)Why was the boy angry with his mother?________A His mother left him alone.B He lost face in front of the cashier.C His mother forgot to buy something.D He had just quarreled with the cashier..(3)Why did Norman bring a spare bulb with him?________A He was always well﹣prepared.B His presentation was about bulbs.C He knew the classroom equipment was of poor quality.D He predicted the bulb on the projector would blow out..(4)What do the two stories tell us?________A Accidents happen almost every day.B Money is the key that opens alldoors. C In fair weather,prepare for a rainy day. D Chances favor those who are well﹣prepared.19. The Netherlands on Monday introduced its first﹣ ever intelligent bicycle, fitted with electronic devices to help handlebar bring down the high accident rate among elderly cyclists in the bicycle﹣mad country.Developed for the government by the Netherlands Organization for Applied Scientific Research (TNO), the intelligent bicycle runs on electricity. It is expected to be on the market in the next two years and should sell for between 1, 700 to 3, 200 euros per bicycle. The devices on the bicycle are linked through an on﹣board computer with a vibrating (振动的)warning system fitted in the bicycle's saddle and handlebars to warn cyclists of the coming danger.The saddle vibrates when other cyclists come nearer from behind, while, the handlebars do the same when barriers(障碍物)appear ahead."Accidents often happen when cyclists look behind them or get a fright when they ride at high speed, " said Maurice Kwakkernaat, one of TNO, s research scientists. "The on﹣board system technology has already been at work in the car industry, " he said."More and more elderly people are using a bicycle, not only for short distances, but also for longer distances, " Dutch Minister of Infrastructure and Environment Melanie Schultz van Haegen told AFP. "This type of bicycle is truly needed in the Netherlands because it will help us bring down the number of elderly people who are injured every year and allow them to continue to enjoy cycling, " she said.In the Netherlands, bicycles outnumber (比……多)the population of 17 million by at least one million and there are some 25, 000 km of bicycle path in the country. Those numbers will surely grow as more and more people take two﹣wheeled transport, leading to an increased risk of injury.Last year, 184 cyclists died in the country, of which 124, or 67%, were older than65, according to the Central Statistics Office. The year before, 200 cyclists died, the majority of victims also being elderly.The model now weighs 25 kilograms but researchers are working on making the on﹣board systems smaller.(1)The intelligent bicycle is aimed to________A protect the environmentB help decrease traffic pressureC popularize the use of bicyclesD improve safety for elderly cyclists.(2)Which part of the intelligent bicycle will vibrate when another cyclist was suddenly found ahead?________A The handlebars.B The wheels.C The saddle.D The on﹣board computer..(3)We can learn from the passage that________.A the elderly ride bicycles wherever they goB the accident rate among elderly cyclists is highC the number of elderly cyclists is decreasingD the elderly are planning to give up cycling.(4)Which is the best title for the passage?________A The Bicycle StructureB Elderly CyclistsC A Smart BicycleD A Bicycle﹣mad Country.20. A generation of parents raised according to the permissive principles of postwar childcare experts is rediscovering the importance of saying"No"to their children.They are beginning to reclaim the house as their own.Even spanking(打屁股)is back.While today's parents do not want to return to the Victorian era (时代)﹣when children were seen, spanked, but not heard﹣there is a growing acknowledgement thatthe________approach produced a generation of children running rings around puzzled parents struggling to restore order.Janthea Brigden, a trainer with Parent Network, says: "The problem is that parents don't want all that controlling things.What they want is to be able to discipline (管教) their children through teaching and encouraging."According to Steve Biddulph, the author of More Secrets of Happy Children, the permissive era was often just an excuse to ignore children.He believes discipline involves firm but friendly teaching and does not need to involve punishment.He teaches a method called"stand and think", where a child is helped to figure out what is wrong and how to get it right.Mr.Biddulph understands parents using spanking, but lie is against it."The happiest children are those who know Mum and Dad are in charge.As children grow into their teens, more negotiation can take place, such as: Prove you can be home safely by 11 pm, and we might let you stay out till midnight.""There is no good evidence that an occasional, properly administered spanking is harmful in any way."says John Rosemond, an American who has won a huge following by calling for"parent power".It is pure nonsense to believe that restricting children to their room as a punishment could make them have negative feelings about the room and cause sleep problems.Mr.Rosemond tracks the overturning of traditional family values to the end of the Second World War.He blames the change of the American family into a child﹣centered, self﹣respect﹣oriented (以…为导向) unit on psychologists and social workers, who for 30 years have weakened traditional approaches.Previous generations of American parents raised children not by the book, but by self﹣evident truth, he says.________He says that those phrases contain time﹣honored understanding and principles that helped children to develop what we refer to as the"three Rs"of parenting: respect, responsibility and resourcefulness.(1)Which is closest to the meaning of the underlined word"laissez﹣faire"in the second paragraph?________A Let it be.B Go for it.C Get it right.D Take it easy..(2)If his child did something wrong,Steve Biddulph would________A give him a good beatingB lock him up in a dark roomC ask him to stand in a corner for hoursD help him find out the problem and solution.(3)By mentioning the underlined part in the last paragraph,Mr.Rosemond________.A blames parents for ignoring children's rightsB reminds parents to communicate more with childrenC encourages parents to involve children more in familyaffairs D explains how previous generations of parents raised children.(4)What does the passage mainly talk about________.A The causes of discipline problems.B The best way to disciplinechildren. C Different opinions on ways of parenting. D Differences between parents of different times.四、七选五21. For people with thousands of pages to read,speed reading seems like a manna (甘露)from heaven.In addition,speed reading helps lighten the load of information you have to absorb since it provides a filter that you can use in screening all bits of information before you approach them.(1)_______Examining how much information you need will help you identify how you should read a certain document to maximize your learning and comprehension.Thorough reading may no longer be necessary in some cases,such as when you only need an outlineof a certain document.Another skill that can ease the burden of a reader is the ability to read words in blocks.Make sure you do not spend too long on a certain block.(2)_______This will also make reading less tiresome and boring.To master this important skill,you have to practice reading more and more words in a certain block at one time.A suggestion shared by some experts regarding this step is to increase the distance between you and the document you are reading.If you can read more and more words in one block,you can cut down on the time it usually takes you to read a certain text and you will be able to read more in a shorter period.Readers should also practice reducing the number of times they go back to previous sections or blocks.Using a pointer such as the tip of a pencil or pen can also help to make the flow of your reading smoother and faster.(3)_______Thus,your speed in reading will largely depend on the speed of the movement of your pointer.If you still find yourself confused about the topic even after you have finished reading the document,do not re﹣read right away.Re﹣reading immediately will just lead to slower speed in reading.(4)_______Getting your own reading corner will also help.(5)_______Continue practicing and practicing the techniques aforementioned and soon,you'll achieve the reading speed that will work best for you.A.In this technique,your eyes will follow the tip of the pointer.B.This saves time and reduces the effort that you have to make.C.Taking a short break first is recommended before reading the material again.D.As a final note,the most important point is consistent and deliberate practice.E.Your invaluable time can be saved if you can have your reading speed doubled.F.The first step to increase your reading speed is to identify the specific information you need.G.Reducing the time you spend on a specific number of words in a block will make no difference.五、提纲类作文22. 第二节书面表达(满分2你得知故宫免费对教师开放,于是给你校外教写一封邮件,包括以下内容:1.开放时间:每月的第一个周三;2.订票方式:提前10天网上预约;3.入场条件:出示教师证。
