6．Any mistake made in the printing of a stamp raises its value to stamp collectors．A mistake on a two-penny stamp has made it worth a million and a half times its face value．
Do you think it impossible？Well，it is true．And this is how it happened．
The mistake was made more than a hundred years ago in the former British colony（殖民地）of Mauritius，a small island in the Indian Ocean．In l847all order for stamps was sent to London Mauritius was about to become the fourth country in the world to put out stamps．
Before the order was filled and the stamps arrived from England，a big dance was planned by the commander-in-chief of all the armed forces on the island．The dance would be held in his house and letters of invitation would be sent to all the important people in Mauritius．Stamps were badly needed to post the letters．Therefore，an islander，who was a good printer，was told to copy the pattern of the stamps．He carelessly put the words"Post Office"instead of"Post Paid"，two words seen on stamps at that time，on the several hundred that he printed．
Today，there are only twenty-six of these misprinted stamps left-fourteen One-penny Reds and twelve Two-penny Blues，Because there are so few Two-penny Blues and because of their age，collectors have paid as much as﹩16，800for one of them．

5．Have you ever remembered something with your nose？Maybe the smell of hot dogs makes you think of being at a baseball game．Or the smell of barbequed meat reminds you of a night around a fire．Scientists know that smells can make people think of powerful memories．Wouldn't it be great to somehow save those memories？
That is exactly what Mark Crames，a businessman making perfumes （香水），is trying to do．His company，Demeter Fragrance，makes more than 200 kinds of perfumes．"Imagine every smell in the world as a musical note，"Crames said．"We try to join those notes to make a piece of beautiful music．"He has made many perfumes and he got the idea from plays，storms and even animals．
Everyday smells mean different things to different people．"A perfume called Poison Ivy might make you think of sadness or surprise，"Crames says．"But it could make another person think of a great time at summer camp．"
Crames produces perfumes using a high-tech method called headspace technology．This month，Crames is making scent for Tootsie Roll and Junior Mints．Not every smell can be easily copied．"One of our most needed perfumes is a little dog's breath，"he says．"But it is so chemically complicated that it's very hard to get．"

4．It is not a good idea to stop the actor Richard Griffiths in the middle of a play．During the past year he had stopped performances many times at the National Theatre when mobile phones rang，and he threw out one member of the audience because she failed to turn off her phone．
So when a mobile rang out for the third time during his performance in Alan Bennett's The History Boys，he spoke angrily to the theatergoer，"I am not going to compete with these electronic devices （装置）．"
Griffiths'actions led to a debate in the UK theatre world over whether phones should be forbidden by law from British theatres．Actors have already asked the govern-
ment to legalize the use of an electronic device that stops mobile phone signals in theatres．
Technology companies have"stopping"devices that send out a high-powered signal on the same frequency as a mobile phone，stopping the mobile phone signals．
However，these are forbidden in many countries because they might stop emergency （紧急情况） calls from being made．
Rosemary Squire，president of the Society of West End Theatre，said，"Phones are one of the biggest problems theatres face．We should look at equipment that could stop phones or make a London-wide theatre rule．"
Nick Allott，the managing director of Sir Cameron Mackintosh's theatre group，said，"We would all welcome some ways of keeping phones from ringing but doctors and emergency workers need to be connected in a theatre and we mustn't stop that．"What can we do to solve the problem？
66．The first two paragraphs are written toC．

3．Parents who feel disappointed at their teenagers'failure to pay attention in class，and inability to sit quietly long enough to finish homework or plan ahead，should take solace．Their children are not being lazy or careless，according to new research．
    The research has found that teenagers'brains continue developing far longer into adulthood than we used to think．Teens may look like young adults but their brain structure is similar to that of much younger children．
"It is not always easy for teens to pay attention in class without letting their minds wander，or to ignore distractions from their younger brothers or sisters when trying to solve a maths   problem，"said Dr Iroise Dumon-theil．"But it's not the fault of teenagers that they can't pay attention and are easily distracted．It's to do with the structure of their brains．Teens simply can't think as well as an adult．"
    The research showed that the brain of a teenager works less effectively than that of an adult．"We knew that the front of the brain of teens functioned in a chaotic （混乱的） way but we didn't realize it continued until the late 20s or early 30s，"said Dr Sarah-Jayne Blakemore，who led the research．
    Chaotic thought patterns are a result of teenagers'brains containing too much grey matter-the cell bodies and connections which carry messages within the brain．As we age，the amount of grey matter in our brain reduces．
"What our research has shown is that there is simply too much going on in the brains of teens，"said Blakemore．"The result is that their brain energy and resources are wasted and their decision-making process is badly influenced．Adults，on the other hand，have less grey matter．This means that the brain works far more effectively．"
63．The underlined word"solace"in Paragraph 1 may meanC．
A．notice      B．medicine    C．comfort     D．action
64．When making decisions，A．
A．teens'brains continue to do much needless work
B．the grey matter in young children's front brain becomes active
C．people are not likely to be distracted until their late 30s
D．adults are more independent than teens

A．It makes us always feel disappointed．
B．It makes us more intelligent．
C．It had a bad effect on the growth of teens．
D．It had a bad effect on decision-making．
66．What's the text mainly about？C
A．Teens have different brains from those of children．
B．Adults work more effectively than teens．
C．Grey matter makes teens unable to pay attention．
D．Brain energy is wasted in the brain's activity．

2．Are you sometimes a little tired and sleepy in the early afternoon？Many people feel this way after lunch．They may think that eating lunch is the cause of the sleepiness．Or，in summer，they may think it is the heat．However，the real reason lies inside their bodies．At that time-about eight hours after you wake up-your body temperature goes down．This is what makes you slow down and feel sleepy．Scientists have tested sleep habits in experiments where there was no night or day．The people in these experiments almost always followed a similar sleeping pattern （模式）．They slept for one long period and then for one short period about eight hours later．
In many parts of the world，people take naps（小睡） in the middle of the day．This is especially true in warmer climates，where the heat makes work difficult in the early afternoon．Researchers are now saying that naps are good for everyone in any climate．A daily nap gives one a more rested body and mind and therefore is good for health in general．In countries where naps are traditional，people often suffer less from problems such as heart disease．
Many working people，unfortunately，have no time to take naps．Though doctors may advise taking naps，employers do not allow it!If you do have the chance，however，here are a few tips about making the most of your nap．Remember that the best time to take a nap is about eight hours after you get up．A short sleep too late in the day may only make you feel more tired and sleepy afterward．This can also happen if you sleep for too long．If you do not have enough time，try a short nap-even ten minutes of sleep can be helpful．
60．Why do people feel sleepy in the early afternoon according to the text？C
A．They eat too much for lunch．

B．All for a Nap
C．A Special Sleep Pattern
D．Taking Naps in Warmer Climate．

1．Everyone knows you must exercise regularly to keep good health．Indeed，staying physically fit is a big part of our culture，we consider （or rightly so） that healthy people are attractive people．Since most of us want to be attractive，there is no shortage of exercise clubs，training videos，magazines and books offering to help us stay physically fit．
Unfortunately，however，our culture doesn't place the same emphasis （重视） on mental fitness．Although we tend to like men and women with strong，healthy-looking bodies，we don't have the same degree of respect or attraction for smart，educated，mentally healthy people．This is a pity，because there are great rewards for people who have developed the ability to think well．
If your mind is well trained and flexible （灵活的），you will be able to understand a great deal of what happens around you．And if you are also well educated-that is，if you understand basic science，mathematics，music，art，literature，history and so on-you will find it much easier to make good decisions throughout your life．Over the long run，this leads to a sense of control over your destiny （命运） and a much better life than otherwise （in another way）．
People who are poorly educated or who don't think well-that is，people who are not mentally fit-see things differently．Their world is controlled by mysterious，often malevolent （恶意的） forces．Such people live within a system they will never master，forced to follow rules they will never understand．Although it may not be obvious，most spend their lives being manipulated （控制） by others．They are told what to do，what to think，how to spend their money，and what they should and should not aspire （渴望） to in life．
In my opinion，if you want to live well，you must be able to use your mind well．For this reason，I want you to be able to concentrate，to solve problems，to understand complex ideas，and to think clearly and quickly．Such skills will make it easier for you to make informed decisions，understand current events，choose good friends，manage your money well，make wise long-term decisions and appreciate music，art and literature．
The key to developing such skills is to enjoy learning，and to have the ability and motivation to teach yourself．

20．"Mummy，I don't know what to play with．"Steve interrupts his mother，who is talking to a friend，for the fourth time．"You've got a room full of toys!"his mother says，impatiently．In fact it is thejumble of toys which is to blame for four-year-old Steve's lack of interest in his dolls，cars and stuffed （packed） animals．Each morning he tips out three washing baskets of toys all over his floor，listlessly pulls out something and shortly after is standing at his mother's desk or following her into the kitchen saying："Mummy，I am bored．"
A family therapist （心理医生） explains why children lose interest when they have a whole"toy shop"at home："According to their brain development，little children are not in a position to judge the quality of a variety of things at once．There is always just one favorite toy for the moment．All the rest is left lying about．"What can parents do to stop their children from being oversupplied with toys？Under no conditions simply make something disappear without the child's knowledge．If he/she takes no more notice of a toy，a parent can ask if it can be stored or given away．Be warned though the child will always say he/she wants it then!A talk with relatives and friends may also help．Lyn is the mother of four-year-old Jessie，and we like her way．A small set of shelves in her child's room holds the toys and books that are the current （at present） favorites．When it seems to her that her daughter is tired of these toys，they put them away in a box together and select some other toys from a cupboard in another room．The box of"old"toys goes into the cupboard．When her child says she is"bored"，they also get something from her cupboard-it may be something she has had for some time but because she hasn't seen it for a while it is almost like a new toy．
Some favorite toys stay out all the time，and there is a collection of dolls which sits in the corner，but in this way Lyn has found that she has fewer toys to put away at the end of the day and her daughter always has something"fresh"to play with．

19．Laptop computers are popular all over the world．People use them on trains and airplanes，in airports and hotels．These laptops connect people to their workplace．In the United States today，laptops also connect students to their classrooms．
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want．Within five years，each of the 1500 students at the college will receive a laptop．The laptops are part of a＄10 million computer program at Westlake，a 110-year-old college．The students with laptops will also have access to the Internet．In addition，they will be able to use e-mail to"speak"with their teachers，their classmates，and their families．However，the most important part of the laptop program is that students will be able to use computers without going to computer labs．They can work with it at home，in a fast-food restaurant or under the trees-anywhere at all!
Because of the many changes in computer technology，laptop use in higher education，such as colleges and universities，is workable．As laptops become more powerful，they become more similar to desktop computers．In addition，the portable computers can connect students to not only the Internet，but also libraries and other resources．State higher-education officials are studying how laptops can help students．State officials are also testing laptop programs at other universities，too．
At Westlake College，more than 60 percent of the staff use computers．The laptops will allow all teachers to use computers in their lessons．As one Westlake teacher said，"Here we are in the middle of Virginia and we're giving students a window on the world．They can see everything and do everything．"

18．When animals and plants use color to be noticed it is called advertising coloration（着色）．Advertising coloration can be used to either warn or attract animals．
The bright colors of flowers and berries ale advertising coloration that attract animals．Flowers need to be pollinated（授粉）to reproduce．Bees and hummingbirds ale attracted to bright colors and will pollinate the flowers．Some pollinated plants will produce berries．These berries will turn a bright color when they are ripe．The bright color lets berry-eating birds know the fruit is sweet and safe to eat．After birds eat the berries，the seeds will pass through their digestive system and be left behind．Some of the seeds left behind will grow into new plants!
Color is also used to attract mates（配偶）．Many male birds like the northern cardinal are brightly colored to attract females．Bright feathers can be a sign of how healthy the bird is!Female birds are naturally attracted to healthier males because their offspring will be healthier．Female birds are often less colorful．This helps hide them when they are nesting．
Advertising coloration is also used to warn animals away．The ladybug has bright orange wings with black spots．Its coloring warns meat-eating animals that the ladybug tastes awful．The striped skunk（带条纹的臭鼬）has white stripes that are a warning to meat-eating animals that they may be in for an unpleasant surprise if they try to attack．
Some animals，like the red-eyed tree frog，may scare enemies away with their color，Red-eyed tree frogs sleep during the day．If a meat-eating animal comes up to them and they open their eyes，the bright red color of their eyes might shock the animal long enough to give the red-eyed tree flog time to hop away to safety．

17．Everyone becomes a little more forgetful as they get older，but men's minds decline（衰退） more than women's，according to the results of a worldwide survey．
    Certain differences seem to be inherent in male and female brains：men are better at dealing with mental images （useful in mathematical reasoning and spatial （三维空间） skills），while women tend to be better at recalling information from their memories （helpful with language skills and remembering the locations of objects）．
  Many studies have looked for a connection between sex and the amount of mental decline people experience as they age，but the results have been mixed．
    Some studies found more age-related decline in men than in women，while others saw the opposite or even no relationship at all between sex and mental decline．Those results could be improper because the studies involved older people，and women live longer than men．The men tested are the survivors，"so they're the ones that may not have shown such cognitive （认知的） decline，"said study team leader Elizabeth of the University of Warwick in England．
    People surveyed completed four tasks that tested sex-related cognitive skills：matching an object to its rotated （旋转的） form，matching lines shown from the same angle，typing as many words in a particular collection as possible in the given time，e．g．"objects usually colored gray"，and recalling the location of objects in a line drawing．The first two were tasks which men are usually good at； the latter are almost controlled by women．
    Within each age group studied，men and women performed better in their separate task on average．Generally speaking，women showed obviously less decline than men though performance declined with age for both sexes．
71．The underlined word"inherent"in the second paragraph meansC．
A．difficult            B．native               C．natural          D．absolute
