Eating Potatoes Gives Your Immune System a Boost
Eating potatoes is not only good for bowel health,but also for the whole immune system,espe- cially when they come in the form of a potato salad or eaten cold.In a study on an animal model, researchers in Spain found that pigs fed large_________(51)of raw potato starch(RPS)not on-ly had a healthier bowel,but also decreased levels of white blood cells,________(52)as leuco- cytes and lymphocytes in their blood.White blood cells are produced as a_________(53)of in-fEammation or disease,generally when the body is challenged.
The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect,a generally more_________(54)body.The reduction in leucocyte levels was about 15 percent.Lower lymphocyte levels are also indicative of_________(55)levels of in-flammation,but the observed reduction in both lymphocyte density_________(56)lymphocyte apoptosis is surprising.
In_________(57)was the longest study of its kind,pigs were fed RPS over 14 weeks to _________(58)the effect of starch on bowel health.“The use of raw potato starch in this experi-ment is_________(59)to simulate the effects of a diet high in resistant starch,”said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona,Spain.
Humans do not eat_________(60)potatoes,but they do eat a lot of foods that contain resist-ant starch,such as cold boiled potatoes,legumes,grains,green bananas,pasta and cereals.About 10 percent of the starch eaten by human is resistant starch—starch that is not_________(61)in the small intestine and so is shunted into the large intestine where it ferments.Starch consumption is thought to reduce the_________(62)of large bowel cancer and may also have an effect on irritable bowel syndrome(IBS).
Immunology expert Lena Ohman' s team_________(63)found that the overall lymphocyte levels do not vary for IBS patients,but that lymphocytes are transferred from the peripheral blood to the gut,which support the hypothesis of lBS being_________(64)least partially an inflammato- ry disorder.

Searching for Smiles
1 Ask most people anywhere in the world what they want out of life and the reply will
probably be:"to be happy."Ed Deiner,an American psychology professor,has spent his
whole professional life studying what makes people happy,comparing levels of happiness
between cultures and trying to find out exactly why we enjoy ourselves.
2 Many people would say that this question does not need an answer.But Professor Deiner
has one anyway."If you're a cheerful,happy person,your marriage is more likely to last,and
you're more likely to make money and be successful at your job.On average,happy people
have stronger immune（免疫的）systems, and there is some evidence that they live longer."
3 So who are the world's happiest people?It depends on how the word is defined.There
is individual happiness,the sense of joy we get when we do something we like.But there is
also the feeling of satisfaction we get when we know that others respect us and approve of
how we behave.According to Professor Deiner,the Western world pursues individual
happiness while Asia prefers mutual satisfaction.
4 "In the West, the individualistic（个人主义的）culture means that your mood matters
much more than it does in the East.People ask themselves,what can I do that's fun or
interesting?They become unhappy when they can't do any of these things.If you ask
people from Japan or China if they are happy,they tend to look at what has gone wrong in
their lives.If not much has gone wrong,then they are satisfied."
5 People from Spain and other Spanish-speaking countries had the happiest culture,Professor
Deiner found."The biggest cultural difference is to do with pride and shame.Hispanic（西班牙
语言的）cultures report much more pride and much less shame than others."
6 Income also made a big difference to people's happiness,but only at the lowest levels.
Average income earners in the US were much happier than people in poverty.But
millionaires were only a little bit happier than people on average incomes.It seems that
money makes us happy when we have enough to feel secure.
7 But can we be too happy? "You get people who are actually happy,but they think
happiness is so important that they try to be even happier.This desire to be always happy is
a product of individualism,where the emphasis is on you individually,your emotions and
feeling good.People can end up feeling unhappy because ordinary happiness is not good
enough for them."

Citizen Scientists
Understanding how nature responds to climate change will require monitoring key life cycle events一
flowering,the appearance of leaves and the first frog calls of the spring一all around the world.But ecologists
can't be everywhere so they're turning to non-scientists,sometimes called citizen scientists,for help.
Climate scientists are not present everywhere.Because there are so many places in the world and not
enough scientists to observe all of them,they're asking for your help in observing signs of climate change
across the world.The citizen scientist movement encourages ordinary people to observe a very specific
research interest一birds,trees,flowers budding,etc.and send their observations to a giant database to be
observed by professional scientists.This helps a small number of scientists track a large amount of data that they
would never be able to gather on their own.Much like citizen journalists helping large publications cover a
hyper-local beat,citizen scientists are ready for the conditions where they live in.All that's needed to become
one is a few minutes each day or each week to gather data and send them in.
A group of scientists and educators launched an organization last year called the National Phenology
Network."Phenology"is what scientists call the study of the timing of events in nature.
One of the group's first efforts relies on scientists and non-scientists alike to collect data about plant
flowering and leafing eveiy year.The program,called Project BudBurst,collects life cycle data on a variety of
common plants from across the United States.People participating in the project一which is open to every-
one一record their observations on the Project BudBurst website.
"People don't have to be plant experts一they just have to look around and see what's in their neighbor-
hood,"says Jennifer Schwartz,an education consultant with the project."As we collect these data,we'll be
able to make an estimate of how plants and communities of plants and animals will respond as the climate
changes."
In"All that's needed to become one…（Paragraph 2)",what does the word"one"stand for?
A:A citizen journalist.
B:A citizen scientist?
C:A scientist.
D:A citizen.

Exercise Can Replace Insulin for Elderly Diabetics
Most old people with so-called type Ⅱ diabetes could stop taking insulin if they would do brisk exercise for 30 minutes just three times a week,according to new medical research results reported in the Copenhagen newspaper Berlingske Tidende on Monday.
Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet's Center
for Muscle Research showed that physical exercise can boost the body's ability to utilise insulin by 30 percent,the newspaper reported.
This is equal to the effect most elderly diabetics get from their insulin medication today,it said.
Researchers had a group of non-diabetic men and a group of men with type II,all more than 60 years of age,exercise on bicycles six times a week for three months.After the three months the doctors measured how much sugar the test subjects'muscles could utilise as a measure for how well their insulin worked.
Associate Professor Dr.Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non-exercising persons.
"This means that the insulin works just as well for both groups.Physical exercise cannot cure people of diabetes,but it can eliminate almost all their symptoms.At the same time it can put off the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment,"Dela was quoted as saying.
Insulin is a hormone produced by the pancreas,controlling sugar in the body and used against diabetes.
Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to work up a sweat,but that the activity has to be maintained since it wears off after five days without sufficient exercise。
Most diabetics realise that they have to watch their diet while remaining unaware of the importance of exercise,Dela added.
How could most elderly type Ⅱ diabetics stop taking insulin?
A:By taking more salt than usual.
B:By taking less salt than usual.
C:By doing brisk exercise for half an hour at least three times a week.
D:By going climbing,swimming or boxing every day.

Why Is the Native Language Learnt So Well?
How does it happen that children learn their mother tongue so well?When we compare them with adults
learning a foreign language,we often find this interesting fact.A little child without knowledge or experience
often succeeds in a complete mastery(精通）of the language,A grown-up person with fully developed mental
powers,in most cases,may end up with a faulty and inexact command（掌握）.What accounts for this
difference?
Despite other explanations,the real answer in my opinion lies partly in the child himself,partly in the
behavior of thle people around him.In the first place,the time of learning the mother tongue is the most fa-
vorable of all,namely,the first years of life.A child hears it spoken from morning till night and,what is
more important,always in its genuine form,wirth the right pronunciation,right intonation,right use of words
and right structure. He drinks in（吸收）all the words and expressions, which come to him in a flash, ever-
bubbling( 冒泡的）spring. There is no resistailce: there is perfect assimilation.
Then the child has,as it were,private lessons all the year round，while an adult language-student has
each week a limited number of hours,which he generally shares withothers.The child has another advan-
tage:he hears the language in all possible situations,always accompanied by the right kind of gestures and
facial expiessiotis.Here there is nothing unnatural,such as is often found in language lessons in schools,
when noe talks aboult ice and snow in June or scorching heat in January.And what a child hears is generally
what immediately interests him.Again and again,when his attempts at speech are successful,his desires are
understood and fulfilled.
Finally,though a child's"teachers"may not have been trained in language teaching,their relations
with him are always close and personal.They take great pains to make their lessons easy.
The reason why children learn their mother tongue so well lies solely in their environment of learning.
A:Right
B:Wrong
C:Not mentioned

One Good Reason to Let Smallpox Live
It's now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980,when smallpox was eradicated in the wild,by destroying the killer vims in the last two labs that are supposed to have it one in the US and one in Russia. if smallpox had truly gone from the planet,what point was there in keeping these reserves?

Mau Piailug,Ocean Navigator
Mau sailed from Hawaii to Tahiti using traditional methods.
In early 1976,Mau Piailug,a fisherman,led an expedition in which he sailed a tradi-tional Polynesian boat across 2,500 miles of ocean from Hawaii to Tahiti.The Polynesian Voyaging Society had organised the expedition.Its purpose was to find out if seafarers（海员） in the distant past could have found their way from one island to the other without naviga-tional instruments,or whether the islands had been populated by accident.At the time,Mau was the only man alive who knew how to navigate just by observing the stars,the wind and the sea.
He had never before sailed to Tahiti,which was a long way to the south.However,he understood how the wind and the sea behave around islands,so he was confident he could find his way.The voyage took him and his crew a month to complete and he did it without a compass or charts.
His grandfather began the task of teaching him how to navigate when he was still a baby.He showed him pools of water on the beach to teach him how the behaviour of the waves and wind changed in different place.Later,Mau used a circle of stones to memorise the positions of the stars.Each stone was laid out in the sand to represent a star.
The voyage proved that Hawaii's first inhabitants came in small boats and navigated by reading the sea and the stars.Mau himself became a keen teacher,passing on his traditional secrets to people of other cultures so that his knowledge would not be lost.He explained the positions of the stars to his students,but he allowed them to write things down because he knew they would never be able to remember everything as he had done.
Mau expected his students to remember the positions of the stars immediately.

Creating a World without Smoking
Smoking will be banned in all pubs,clubs and workplaces from next year after historic votes in the Commons last night.Afler last-minute appeals from health campaigners,MPs opted for a blanket prohibition which will startin summer 2007,ending months of argument over whether smokers should be barred in pubs and restaurants only.They voted to ban smoking in all pubs and clubs by 384 to 184,a surprisingly large majority of 200.
Smoking will still be allowed in the home and in places considered to be homes,such as prisons,care homes and hotels.
Smokers lighting up in banned areas will face a fixed penalty notice of ￡50 and spot fines of ￡ 200 will be introduced for failing to display no-smoking signs,with the possible penalty,if the issue goes to court,increasing to ￡1,000.
Carpline Flint,the Public Health Minister,also announced that the fine for failing to stop people smoking in banned areas would be increased to￡2,500 more than ten times the￡200 originally proposed.
The Bill also allows the Government to increase the age for buying cigarettes.Ministers will consult on raising it from 16 to 18.
The Bill now goes to the Lords but will be through by the summer recess.
Even a plan to allow smoking to continue in private clubs was thrown out as MPs on all sides were given permission to vote with their conscience rather than on a party line.
Patricia Hewitt,the Health Secretary,said the Health Bill would ban smoking in"virtually every enclosed public place and workplace"in England and save thousands of lives a year. Smoke-free workplaces and public places"will become the norm".
She said:"An additional 600,000 people will give up smoking as a result of this law and millions more will be protected from second-hand smoke."
Peter Hollins,director-general of the British Heart Foundation,said:"The vote is a landmark victory for the public health of this country and will save the lives of many people."
There is a possibility for the Government to raise the age for buying cigarettes.

Medical Journals Medical journals are publications that report medical information to physicians and other health professionals. In the past,these journals were available only in print.With the development of electronic publishing, many medical journals now have web sites on the Internet,and some journals are published only online.A few medical journals,like the Journal of the American Medical Association,are considered general medical journals because they cover many fields of medicine.
Most medical journals are specialty journals that focus on a particular area of medicine. Medical journals publish many types of articles.Research articles report the results of research studies on a range of topics varying from the basic mechanisms of diseases to clinical trials that compare outcomes of different treatments.
Review articles summarize and analyze the information available on a specific topic based on a careful search of the medical literature.Because the results of individual research studies can be affected by many factors,combining results from different studies on the same topic can be helpful in reaching conclusions about the scientific evidence for preventing,diagnosing or treating a particular disease.
Caseconferences and case reports may be published in medical journals to educate physicians about particular illnesses and how to treat them.Editorials in medical journals are short essays that express the views of the authors,often regarding a research or review article published in the same issue.Editorials provide a perspective on how the current article fits with other information on the same topic.
Letters to the editor provide a way for readers of the medical journal to express comments,questions or criticisms about articles published in that journal.

Operation Migration
If you look up at the sky in the early fall in the northern part of North America,you may see groups of
birds.These birds are flying south to places where they can find food and warmth for the winter. They are
migrating（迁徙）.The young birds usually learn to migrate from their parents. They follow their parents
south.In one unusual case,however,the young birds are following something very different.These birds
are young whooping cranes and they are following an airplane!
The whooping crane is the largest bird that is native to North America.These birds almost disappeared
in the 1 800s.By 1941,there were only about 20 cranes alive.In the 1970s,people were worried that these
creatures were in danger of disappearing completely.As a result,the United States identified whooping
cranes as an endangered species that they needed to protect.
Some researchers tired to help.They began to breed whooping cranes in special parks to increase the
number of birds.This plan was successful,There were a lot of new baby birds.As the birds became older,
the researchers wanted to return them to nature.However,there was a problem:these young birds did not
know how to migrate,They needed human help.
In 2001,some people had a creative idea.They formed an organization called Operation Migration.
This group decided to use very light airplanes,instead of birds,to lead the young whooping cranes on their
first trip south.They painted each airplane to look like a whooping crane.Even the pilots wore special clothing
to make them look like cranes.The cranes began to trust the airplanes,and the plan worked.
Today,planes still lead birds across approxlmately 1,200 mniles(1,931 kilometers),from the United
States-Canadian border to the Gulf of Mexico.They leave the birds at different sites.If a trip is successful,
the birds can travel on their own in the future.Then,when these birds become parents,they will teach their
young to migrate.The people of Operation Migration think this is the only way to maintain the whlooping
crane population.
Operation Migration works with several other organizations and government institutes.Together,they as-
sist hundreds of cranes each year. However,some experts predict that soon this won't be necessary.Thanks
to Operation Migration and its partners,the crane population will continue to migrate.Hopefully,they won't
need human help any more.
Whooping cranes are native to_________.
A:Mexico
B:South America
C:the Persian Gulf
D:North America

His Own Way to Express Love
Yesterday was our three-year anniversary.We didn't do anything romantic;we just walked hand in hand and talked about our past and the future.This was pretty much what I had expected.
Andy is an unromantic guy : no sweet words or roses.Smart as he is,he is a little bit shy expressing his love. In contrast , I am an outspoken（直言不讳）girl who likes to show her feelings directly .So needless to say,I often feel that he is insensitive.I envy other girls who are surrounded by sweet words.
I was in this sullen mood until I heard a beautiful sentence one day:“If one does not love you in the way you like,it does not mean that he does not love you.”This simple but sensible sentence made me think about our happy days and recall his deep concern for me.
One cold winter night,I got a high fever. He hurried to my dormitory and took me to the hospital.He was in such a hurry that he even forgot to wear socks.After arrival,he ran through the hospital handling all the formalities（手续）.When I was put on a drip（点滴）,he told me interesting stories to make me happy. Being held in his warm arms and listening to his tender（温柔的）voice,I had never felt so safe and comfortable.Gradually,I fell asleep.When I woke up 15 minutes later , he was still mumbling（咕浓地说）to me. He explained that if he had stopped talking I would have woken up.At that moment,I found love in his eyes.
Another time,I had a bad quarrel with my best friend.Although I knew it was my fault,I refused to admit it.I was angry when he insisted I apologize to her. He said that it was difficult to admit a mistake,but this was what everyone should do. The next morning,I apologized to my friend and asked for her forgiveness.
My unromantic boyfriend cares about my health like my father,understands me like my mother and helps me like my elder brother.
The word“sullen”in paragraph 3 could be best replaced by______.
A: “cheerful”
B: “calm”
C: “good”
D: “bad”

Aromatherapy（芳香疗法）
1 Aromatherapy is a form of alternative medicine which is based on the use of very concentrated"es-sential"oils from the flowers,leaves,bark,branches or roots of plants which are considered to have healing properties.In aromatherapy these powerful oils are mixed with other oils , such as almond（杏仁）oil, or they are diluted（稀释）with water.These solutions（溶液剂）can be rubbed on the skin,sprayed in the air, or applied as a compress（敷药）.
2 Many people have aromatherapy massages（按摩）,and depending on the treatment a person is having, the aromatherapist will massage the oil into the hands or shoulders.The massage is smooth and flowing,as it is designed to create a sense of relaxation and calm.The sessions are tailored to the individual's health and mood at the time,so every session is unique.
3 Practitioners of aromatherapy believe that the aroma of the"essential"oils directly stimulates the brain or that the oils are absorbed through the skin into the bloodstream,where they can affect the whole body and promote healing.Other claims in support of aromatherapy are that it aids digestion,improves the functioning of respiratory system,reduces muscular aches and pains,and promotes muscle relaxation and tone.It has also been argued that aromatherapy can improve circulation,lower blood pressure,and help combat insomnia（失眠）and other stress-related disorders such as tension headaches , anxiety , and mild depression.
4 However,while aromatherapy may have real effects that promote a sense of well-being,some tradi- tional medicine practitioners remain doubtful about its powers.While research has confirmed that aroma-therapy does have some positive short-term effects on most people,it also suggests that aromatherapy is not an actual science or medicine that should be used to treat illness.Furthermore,not all aromatherapy is considered beneficial to health.There are precautions which should be taken before having aromatherapy because some oils can have negative effects on people with certain medical conditions.The study of aroma-therapy is relatively new and unexplored.More research needs to be conducted to make scientific conclusions about its use and effects.
The sessions of aromatherapy massages are designed to______.
A:have healing effects
B:be used externally
C:be promoted
D:help the disabled
E:be further explored
F:suit different people
