  Ask Dr?JeffersThis month Dr.Jeffers is answering questions about the human brain and how it works.
Dear Dr.Jeffers,
One of my colleagues,Felix Moeller,told me that scientists are learning to use computer to‘read minds'.Is there any truth to this story/
-Jane Leon,New York,USA
Dear Ms.Leon,
Well,a lot of research is being conducted in this area,but so far,the brain scanning equipment and corresponding computer programs haven't been able to actually read thoughts.In one experiment,tes t subjects(受试者)were connected to scanning equipment and shown two numbers on a screen.They were then asked to choose between adding or subtra cting(减)the two numbers.Using this method,researchers were able to follow brain processes and make the correct assumptions(假设)70 percent of the time.It's not quite mind reading,but it's certainly a first step.
-Dr.J.
Dear Dr.Jeffers,
My three-year-old son loves it when I dig my fingers into his sides and tickle (胳肢)him until he laughs uncontrollably.The other day I noticed him trying to tickle himself but he couldn't do it.Why not?
-Glenn Lewis,Vancouver,Canada
Dear Mr.Lewis,
It's because of how the brain works.The brain is trained to know what to pay attention to and what to ignore.It causes us to ignore physical feelings we expect to happen,but it causes a mild panic reaction when there is an unexpected feeling.For example,you don't notice how your shoulder feels while you're walking down the street.But if someone comes up behind you and touches you lightly on the shoulder,you may jump in fear.It's that unexpected part that causes the tickle reaction.
-Dr.J.

8.The 2012 London Olympics had enough problems to worry about.But one more has just been added-a communications blackout caused by solar storms.
     After a period of calm within the Sun,scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012,just in time for the arrival of the Olympic torch in London.
     Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth,causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.
"The Sun's activity has a strong influence on the Earth.The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites,"said Professor Richard Harrison,head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
     At the peak of the cycle,violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Sun's atmosphere,throwing out great quantities of electrically-charged matter."A coronal mass ejection can carry a billion tons of solar material into space at over a million    kilometres per hour.Such events can expose astronauts to a deadly amount,can disable satellites,cause power failures on Earth and disturb communications,"Professor Harrison added.The risk is greatest during a solar maximum when there is the greatest number of sunspots.
     Next week in America,NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO),which will take images of the Sun that are 10 times clearer than the most advanced televisions available.
     The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.
     Professor Richard Hold away,the lab's director,said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth"If we have advance warning,we'll be able to reduce the damage.What you don't want is things switching off for a week with no idea of what's caused the problem,"he said.

72.The phrase"communications blackout"in paragraph 1 most probably refers toB during the 2012 Olympics.
    A.the extinguishing of the Olympic torch
    B.the collapse of broadcasting systems
    C.the transportation breakdown in London
    D.the destruction of weather satellites
73.What can be inferred about the solar activity described in the passage?D
     A.The most fatal matter from the corona falls onto Earth.
     B.The solar storm peak occurs in the middle of each cycle.
     C.It takes several seconds for the charged matter to reach Earth.
     D.The number of sunspots declines after coronal mass ejections.
74.According to the passage,NASA will launch a satellite toC
    A.take images of the solar system    B.provide early warning of thunderstorms
    C.keep track of solar activities     D.improve the communications on Earth
75.Which of the following might be the best title of the passage?D
   A.Solar Storms:An Invisible Killer
   B.Solar Storms:Earth Environment in Danger
   C.Solar Storms:Threatening the Human Race
   D.Solar Storms:Human Activities to Be Troubled.

7.Driving a car is not just handling controls and judging speed and distance.It requires you to predict what other road users will do and get ready to react to something unexpected,When alcohol is consumed,it enters your bloodstream and acts as a depressant (抑制药),damaging eyesight,judgment and co-ordination (协调),slowing down reaction time and greatly increasing the risk of accidents.Even below the drink driving link,driving well be affected.
    Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain.Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice.To get rid of alcohol from the body is a very slow process and it is not possible to speedit up with any measures like taking a shower or having a cup of tea or coffee.
The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is:

●22micrograms of alcohol per 100ml of breath;or
●67milligrams of alcohol per 100ml of urine(尿液)
     Drivers who cause traffic accidents,or who commit a moving traffic offence or are being suspected of drink driving will be tested.
    Any drive found drinking beyond the limit will be charged.The driver declared guilty may be fined a maximum of HK﹩25,000and be sentenced to up to 3years in prison and punished for 10driving-offence points; or temporarily banned from driving.
    The same punishment applices to failing to provide speciments(样本) far breath,blood or urine tests without good excuse.
    Drink driving is a criminal offebce.Be a responsible,driver,think before you drink.For the safety of yourself and other road users,never drive after consuming alcohol.

56.The first paragraph is mainly aboutC.
A.the introductions of driving skills   B.the dangaga of drinking to your body
C.the effect of drinking on driving      D.the process of alcohol being absorbed
57.The underlined word"it"in the second paragraph refers to"D".

6.The term"multitasking"originally referred to a computer's ability to carry out several tasks at one time.For many people,multitasking has become a way of life and even a key to success.In fact,some excellent mental aerobic exercises (大脑训练) involve engaging the brain in two or more challenging activities at a time.Although checking e-mail while talking on a phone and reading the newspaper may be second nature for some people,many times multitasking can make us less productive,rather than more.And studies show that too much multitasking can lead to increased stress,anxiety and memory loss.
In order to multitask,the brain uses an area known as the prefrontal cortex (前额叶脑皮层).Brain scans of volunteers performing multiple tasks together show that as they shift from task to task,this front part of the brain actually takes a moment of rest between tasks.You may have experienced a prefrontal cortex"moment of rest"yourself if you've ever dialed (拨电话) a phone number and suddenly forgotten who you called when the line is answered.What probably occurred is that between the dialing and the answering,your mind shifted to another thought or task,and then took that"moment"to come back.Research has also shown that for many volunteers,job efficiency (效率) declines while multitasking,as compared to when they perform only one task at a time.
Multitasking is easiest when at least one of the tasks is habitual,or requires little thought.Most people don't find it difficult to eat and read the newspaper at the same time.However,when two or more attention-requiring tasks are attempted at one time,people sometimes make mistakes.
We often don't remember things as well when we're trying to manage several details at the same time.Without mental focus,we may not pay enough attention to new information coming in,so it never makes it into our memory stores.That is one of the main reasons we forget people's names-even sometimes right after they have introduced themselves.Multitasking can also affect our relationships.If someone checks their e-mail while on the phone with a friend,they may come off as absent-minded or disinterested.It can also cause that person to miss or overlook key information being passed on to them.

49.Why are some mental aerobic exercises designed to engage people in multitasking?A
A.To make them more productive.
B.To reduce their stress and anxiety.
C.To develop their communication Skills.
D.To help them perform daily tasks more easily.
50.According to Paragraph 2,why may a person suddenly forget who he has called?
B
A.He may have his prefrontal cortex temporarily damaged.
B.He is probably interrupted by another task.
C.He is probably not very familiar with the person he has called.
D.He may need a rest between dialing and speaking.
51.People tend to make mistakes whenA.
A.they perform several challenging tasks at a time
B.new messages are processed one after another
C.their relationships with others are affected
D.the tasks require little thought
52.What is the main idea of the passage?B
A.Multitasking has become a way of life.
B.Multitasking often leads to efficiency decline.
C.Multitasking exercises need to be improved.
D.Multitasking enables people to remember things better.

5.Humans are naturally drawn to other life forms and the worlds outside of our own.We take delight in the existence of creatures and even whole societies beyond our everyday lives.
  This sense of wonder is universal.Look at the efforts that scientists have made to find out whether life of some kind exists on Mars,and the popularity of fantasy(幻想) literature or movies like The Lord of the Rings.This sense of wonder draws us to each other,to the world around us,and to the world of make-believe.But have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already exist all around us?
   Human beings,as biologists have suggested,possess an inborn desire to connect with and understand other life forms.However,people,especially in big cities,often lead rather isolated lives.In a study of British schoolchildren,it was found that children by age eight were much more familiar with characters from television shows and video games than with common wildlife.Without modern technology,a small pond could be an amazing world filled with strange and beautiful plants,insects,birds,and animals.When we lack meaningful interaction(交互) with the world around us,and sometimes even with our families and friends,we seek to understand and communicate with things that exist only in our imaginations or on a computer screen.
   The world of make-believe is not necessarily bad.But when the world of fantasy becomes the only outlet(出路) for our sense of wonder,then we are really missing something.We are missing a connection with the living world.Other wonderful worlds exist all around us.But even more interesting is that if we look closely enough,we can see that these worlds,in a broad sense,are really part of our own.

72.The popularity of The Lord of the Rings provesD
A.the close connection between man and the fantasy world
B.the wonderful achievements of fantasy literature
C.the fine taste of moviegoers around the world
D.the general existence of the sense of curiosity
73.What can we infer from the underlined sentence in Paragraph 3?B
A.People are far less familiar with the world of fantasy.
B.The world around us could serve as a source of wonder.
C.The world of fantasy can be mirrored by a small and lively pond.
D.Modern technology prevents us from developing our sense of wonder.
74.If our sense of wonder relies totally on the world of make-believe,we willA
A.fail to appreciate the joy in our lives
B.be confused by the world of make-believe
C.miss the chance to recognize the fantasy world
D.be trapped by other worlds existing all around us
75.What is the main purpose of the passage?B
A.To show us the hidden beauty in our world.
B.To warn us not to get lost in the fantasy world.
C.To argue against the misuse of the sense of wonder.
D.To discuss the influence of the world of make-believe.

4.It was once common to regard Britain as a society with class distinction.Each class had unique characteristics.
In recent years,many writers have begun to speak the'decline of class'and'classless society'in Britain.And in modern day consumer society everyone is considered to be middle class.
But pronouncing the death of class is too early.A recent wide-ranging society of public opinion found 90percent of people still placing themselves in particular class; 73percent agreed that class was still a vital part of British society; and 52percent thought there were still sharp class differences.Thus,class may not be culturally and politically obvious,yet it remains an important part of British society.Britain seems to have a love ofstratification.
One unchanging aspect of a British person's class position is accent.The words a person speaks tell her or his class.A study of British accents during 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice,Most people said this accent sounded'educated'and'soft'.The accents placed at the bottom in this study,on the other hand,were regional(地区的)city accents.These accents were seen as'common'and'ugly'.However,a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least.This suggests that British attitudes towards accent have deep roots and are based on class prejudice.
In recent years,however,young upper middle-class people in London,have begun to adopt some regional accents,in order to hide their class origins.This is an indication of class becoming unnoticed.However,the 1995pop song'Common People'puts forward the view that though a middle-class person may'want to live like common people'they can never appreciate the reality of a working-class life.

41.A recent study of public opinion shows that in modern BritainD.
A.it is time to end class distinction
B.most people belong to middle class
C.it is easy to recognize a person's class
D.people regard themselves socially different

3.When I was nine years old,I loved to go fishing with my dad.But the only thing that wasn't very fun about it was that he could catch many fish while I couldn't catch anything.I usually got pretty upset and kept asking him why.He always answered,"Son,if you want to catch a fish,you have to think like a fish",I remember being even more upset then because,"I'm not a fish!"I didn't know how to think like a fish.Besides,I reasoned,how could what I think influence what a fish does?
As I got a little older I began to understand what my dad really meant.So,I read some books on fish.And I even joined the local fishing club and started attending the monthly meetings.I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature.That is why fish prefer shallow water to deep water because the former is warmer.Besides,water is usually warmer in direct sunlight than in the shade.Yet,fish don't have any eyelids(眼皮) and the sun huts their eyes…The more I understood fish,the more I became effective at finding and catching them..
When I grew up and entered the business world,I remember hearing my first boss say,"We all need to think like sales people."But it didn't completely make sense.My dad never once said,"If you want to catch a fish you need to think like a fisherman."What he said was,"You need to think like a fish."Years later,with great efforts to promote long-term services to people much older and richer than me,I gradually learned what we all need is to think more like customers.It is not an easy job.I will show you how in the following chapters.

31.Why was the author upset in fishing trips when he was nine?A
A.He could not catch a fish.
B.His father was not patient with him.
C.His father did not teach him fishing.
D.He could not influence a fish as his father did.
32.What did the author's father really mean?D
A.To read about fish.
B.To learn fishing by oneself.
C.To understand what fish think.
D.To study fishing in many ways.
33.According to the author,fish are most likely to be foundD.
A.in deep water on sunny days
B.in deep water on cloudy days
C.in shallow water under sunlight
D.in shallow water under waterside trees.
34.After entering the business world,the author foundB.
A.it easy to think like a customer
B.his father's fishing advice inspiring
C.his first boss's sales ideas reasonable
D.it difficult to sell services to poor people
35.This passage most likely comes fromB.

2.Here is some must-know information from a handbook on how people behave in doing business in some countries.
In Brazil
  Brazilians are warm and friendly.They often stand close when talking and it is common for them to touch the person on the shoulder.People often greet each other (particularly women) with light cheek kisses.Schedules tend to be flexible,with business meetings sometimes starting later than planned.But to be safe,be on time.Meals can stretch for hours-there's no such thing as rushing a meal in Brazil.Lunches also can start in the mid to late afternoon.Brazilians are social,preferring face-to-face communication over mails or phone calls.
In Singapore
  Singaporeans shake hands when they meet and often also greet each other with a small,polite bow.Business cards should be offered and received with two hands.Arriving late is considered disrespectful.So be on time.Efficiency(效率) is the goal,so meetings and dealings often are fast-paced.Singaporeans are direct in their discussions,even when the subject is about money.Rank is important and authority is respected.This determines both people interact in meetings.For example,people avoid disagreeing outright with someone with a higher rank.
In the United Arab Emirates
  In the UAE,status is important,so the most senior or oldest should be greeted first with their titles.The handshake seems to be longer than elsewhere.So,do not pull away the handshake.Women should cover themselves when it comes to dress.Men also tend to be covered from neck to elbows(肘部) and down to the knees.People do not avoid entertaining in their homes,but they also hold business meals at restaurants.Touching or passing food or eating with your left hand is to be avoided.When meetings are one-to-one,if your host offers you coffee,you should refuse.It might seem odd,but it is a cultural tradition.Coffee should only be accepted if it is always set out or presented.
In Switzerland
  The Swiss tend to be formal and address each other by last name.They also are respectful of private lives.You should be careful not to ask about personal topics.Punctuality (守时) is vital,something that comes from a deep respect for others'time.Arrive at any meeting or event a few minutes early to be safe.They also have clear structure in their companies.Higher-ups make the final decisions,even if others might disagree.Neat,clean dress is expected.The Swiss follow formal table manners.They also keep their hands visible at the table and their elbows off the table.It is polite to finish the food on your plate.

1.For more than twenty years scientists have been seeking to understand the mystery of the‘‘sixth sense"of direction.By trying out ideas and solving problems one by one,they are now getting closer to one answer.
One funny idea is that animals might have a built-in compass(指南针).
Our earth itself is a big magnet(磁体).So a little magnetic needle that swings freely lines itself with the big earth magnet to point north and south.When people discovered that idea about athousand years ago and invented the compass,it allowed sailors to navigate (航海)on oceanvoyages,even under cloudy skies.
Actuallly the idea of the living compass came just from observing animals in nature.
Many birds migrate twice a year between their summer homes and winter homes.Some of them fly for thousands of kilometers and mostly at night.Experiments have shown that some birds can recognize star patterns.But they can keep on course even under cloudy skies.How can they do that?
A common bird that does not migrate but is great at finding its way home is the homing pigeon.Not all pigeons can find their way home.Those that can are very good at it,and they have been widely studied.
One interesting experiment was to attach little magnets to the birds'heads to block their magnetic sense-just as a loud radio can keep you from hearing a call to dinner.On sunny days,that did not fool the pigeons.Evidently they can use the sun to tell which way they are going.But on cloudy days,the pigeons with magnets could not find their way.It was as if the magnets had blocked their magnetic sense.
Similar experiments with the same kind of results were done with honeybees.These insects also seem to have a special sense ot direction.
In spite of the experiments,the idea of an animal compass seemed pretty extraordinary.How would an animal get the magnetic stuff for a compass.
An answer came from an unexpected source.A scientist was studying bacteria that live in the mud of ponds and marshes.He found accidentally little rod-like bacteria that all swam together in one direction-north.
Further study showed that each little bacterium had a chain of dense particles inside,which proved magnetic.The bacteria had made themselves into little magnets that could line up with the earth's magnet.
The big news was that a living thing,even a simple bacterium,can make magnetite.That led to a search to see whether animals might have it..By using a special instrument called magnetometer,scientists were able to find magnetite in bees and birds,and even in fish.In each animal,except for the bee.the magnetic stuff was always in or closer to the brain.
Thus the idea of a built-in animal compass began to seem reasonable.
The Magnetic Sense-The Living Compass
Passage outlineSupporting details
The existence of the earth magnet and the invention of the navigating compass◇Our earth is a big magnet and a little freely (71)swinging
magnetic needle lines itself with the earth magnet to point north and south.
◇(72)Basedon the idea above,the navigating compass was invented.
The possibility of birds'built-in compasses◇One piece of evidence is the (73)migrationof many birds between their summer homes and winter homes.
◇Birds can recognize star patterns on clear nights and keep on course (74)even under cloudy skies
The  (75)experiments/tests/study/research on pigeons'and bees'built-in compasses◇Little magnets were tied to the pigeons'heads to (76)block their magnetic sense.
◇The pigeons'magnetic sense seemed to be affected on (77)cloudydays.
◇Similar things with the same results were done with bees.
The  (78)discovery of the magnetic stuff for the animal compass◇Little rod-like bacteria were found by chance to swim together in the direction of (79)north.
◇Some animals had a chain of dense magnetic particles in or close to the (80)brain(s) inside their bodies.
