troubles, viral infections, and higher death rates.What they didn"t know is how this feeling causes illness.
A study in the September issue of the online journal Genome Biology suggests that loneliness actually
affects the very core of our bodies-our genes.
In a small population of patients, researchers surveyed more than 20,000 genes using DNA skills to
compare how the genes of lonely
and nonlonely individuals express themselves in molecular (分子) processes and, ultimately, in personal health.They found that gene expression is different at 209 sites in
chronically lonely people and that many of those changes fit a pattern of elevated immune activation,
inflammation (炎症), and depressed response to infection."We now have a molecular framework for
understanding the relationship between social experience and physical health, "explains the study"s lead
author, Steve Cole.
The study found that loneline
ss decreases the response of some body receptors, cutting off the immune control and anti－inflammatory effects of the stress－related hormone that also helps regulate the
conversion of carbohydrates (碳水化合物) to energy.The depressed response of the stress－related
hormone concurs with the known effects of loneliness and provides a potential target for treatment.
"This study-the first to link feelings with gene changes-is in some sense groundbreaking, "says Emma
Adam, an associate professor at Northwestern University."It fills in the black box."
According to John Cacioppo, an author of the study and a psychologist from the University of
Chicago, the work suggests that loneliness is a warning sign, much like physical pain."This very process
of feeling bad because of disconnection contributes to what it means to be human, "he says."It makes us
care for other people and want to reconnect when we"re disconnected."
B. have bad and little genes
C. are full of energ
D. are quick to the responses of some body receptors
B. Researchers and doctors can deal with loneliness by regulating the stress－related hormone.
C. Loneliness is a warning sign of physical pain.
D. The study of loneliness is of little value at present.
B. the process of feeling bad
C. lon

B. Take more social activities.
C. Take more physical exercises.

举一反三
is born with.Human brains differ considerably, some being more capable than others.But no matter
how good a brain he has to begin with, an individual will have a low order of intelligence unless he has
opportunities to learn.So the second factor is what happens to the individual-the sort of environment in
which he is reared.If an individual is handicapped environmentally, it is likely that his brain will fail to
develop and he will never attain the level of intelligence of which he is capable.
The importance of environment in determining an individual"s intelligence can be demonstrated
by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical
brains at birth, and their growth processes were the same.When the twins were three months old, their
parents died, and they were placed in separate foster homes.Peter was reared by parents of low
intelligence in an isolated community with poor educational opportunities.Mark was reared in the home
of well－to－do parents who had been to college.He was read to as a child, sent to good schools, and
given every opportunity to be stimulated intellectually.This environmental difference continued until the
twins were in their late teens, when they were given tests to measure their intelligence.Mark"s I. Q.was
125, twenty－five points higher than the average and fully forty points higher than his identical brother.
Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.
B. Intelligence and Environment
C. The Case of Peter and Mark
D. How the Brain Influences Intelligence
B. the brain a person is born with is important in determining his intelligence
C. environment is vital to determine a person"s intelligence
D. persons having identical brains will have roughly the same intelligence
B. 100
C. 110
D. 125
B. an individual"s intelligence is determined only by his environment
C. lack of opportunity blocks the growth of intelligence
D. changes of environment produce changes in the structure of the brain
B. stays the same throughout his life
C. can be increased by education
D. is determined by his childhood
suicide (自***). The marriage fails because of the husband"s obsessive (沉迷的) behaviour.
Is this just another story of social breakdown in the modern age?Not really.But they are the effects
of a real social problem--Internet Addiction (上瘾). Or, Internet Addiction disorder.
There have been few long-term studies of this very 21st century illness.
But the extension of the obsession is obvious from the popularity of one game alone:"Halo 2". It"s a
first-person shooter developed by Budgie Studios for the Xbox video game console.By early 2005,1
million players worldwide had clocked up an amazing 100 million hours on the game.
China has about 94 million regular Internet users.Of these, a survey suggested,4.4 million are
teenagers so addicted to it that they neglect everything else.
Video gamers who have gone too far display symptoms similar to those of alcohol and drug abusers.
"The real world meant nothing to me when I was fully involved with online games.I lost track of time,
space, hunger, pain, everything, " explained Liu Pinyi, a 19-year-old college dropout.She has had
treatment in Beijing for her addiction.
What makes it similar to drugs is that online game addicts also develop a chemic
al imbalance in the brain.Gaming stimulates (刺激) the production of a chemical compound that produces euphoric or
pleasant feelings.When they"re away from the screen, their levels of chemicals produce this" high" drop.
And the addict suffers feelings of anxiety and headaches.
Experts say young people are attracted to video games partly because they are thrust right into the
centre of the action.This allows them to overcome a lack of confidence which people at that age can
often suffer from.
But, addiction is not the only problem.A Harvard University survey of 81 video games in 2004 found
that 98 percent contained violence for 36 percent of the total playing time.
China strengthened controls on computer games again this week, with the Mi
nistry of Culture banning nine online games.The ministry said it would also force game operators to technically filter out content that could cause addiction.
B. show how serious the problems are if we use the Internet too much
C. direct the readers to the topic of the passage
D. show his worries about the problems in the modern age
B. online games are really harmful
C. game players are worldwide
D. game players are easy to be obsessive
B. Web Brings About Serious Social Problems
C. The Internet and Its Disadvantages
D. Online Games and Their Harm
B. lack of confidence in reality
C. have no other interests
D. want to avoid the real world
B. cover up
C. reduce
D. control
read letters,reports,trade publications,interoffice communications,not to mention newspapers
and magazines;a never-ending flood of words.In 1 a job or advancing in one,the ability to
read and comprehend 2 can mean the difference between success and failure.Yet the unfortunate
fact is that most of us are 3 readers.Most of us develop poor reading 4 at an early age,and never
get over them.The main deficiency(缺陷)5 in the actual stuff of language itself-words.Taken
individually,words have 6 meaning until they are strung together into phrases,sentences and
paragraphs.7 however,the untrained reader does not read groups of words.He laboriously reads
one word at a time,often regressing to 8 words or passages.Regression,the tendency to look back
over 9 you have just read,is a common bad habit in reading.Another habit which 10 down the
speed of reading is vocalization-sounding each word either orally or mentally as 11 reads.
To overcome these bad habits,some reading clinics use a device called an 12,which moves a
bar(or curtain)down the page at a predetermined speed.The bar is set at a slightly faster rate 13 the
reader finds comfortable,in order to "stretch" him.The accelerator forces the reader to read fast,14
word-by-word reading,regression and subvocalization,practically impossible.At first 15 is sacrificed
for speed.But when you learn to read ideas and concepts you will not only read faster,16 your
comprehension will improve.Many people have found 17 reading skill greatly improved after some
training.18 Chalice Au,a business manager,for instance,his reading rate was a reasonably good 172
words a minute 19 the training,now it is an excellent 1378 words a minute.He is delighted that how
he can 20 a lot more reading materials in a short period of time.

concentrated work.This difficulty is much greater for those who do not work to a plan
and have no regular routine of study.Many students muddle along(无计划地进行),
doing a bit of this subject or that,as the mood takes them,or letting their set work pile
up until the last possible moment.
Few students work to a set timetable.They say that if they did work out a timetable
for themselves they would not keep to it,or would have to change it frequently,since they
can never predict(foresee)from one day to the next what their activities will be.
No doubt some students take much more kindly to a regular routine than others.There
are many who shy away from a self-controlled weekly timetable,and dislike being tied
down to a fixed program of work.Many able students state that they work in cycles.When
they become interested in a topic they work on it attentively for three or four days at a time.
On other days they avoid work completely.It has to be admitted that we do not fully
understand the motivation to work.Most people over 25 years of age have become used
to a work routine,and the majority of really productive workers set aside regular hours for
the more important areas of their work.The "tough-minded" school of workers doesn"t fully
accept the idea that good work can only be done naturally,under the influence of inspiration.
Those who believe that they need only work and study as the fit takes them have a mistaken
belief either in their own talent or in the value of "freedom".Freedom from control and discipline
(纪律)leads to unhappiness rather than to "self-expression" or "personality development".Our
society insists on regular habits,timekeeping and punctuality,and whether we like it or not,if we
mean to make our way in society,we have to meet its demands.
B.the failure to keep to a set timetable of work
C.the unwillingness to follow a systematic plan
D.working on a subject only when one feels like it
B.Many students don"t like being told to study to a fixed timetable.
C.Most people over 25 years of age don"t work to set timetable.
D.Tough-minded people agree that good work is done naturally.
B.when they are in the mood
C.when they feel fit
D.when they find conditions suitable
B.A Study Plan
C.The Difficulties of Studying
D.Study and Self-discipline
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
Not long ago, I opened an e-mail from Jennifer, a lady I knew through business in Guelph, Ontario,
Canada, "I have been seeing how I feel after interacting with different people and thinking who I feel good about, 1 "
Then she invited me and eleven other women to a "Movie Night" to be held every six weeks at her
house. She promised we were sure to enjoy a good time. 2 She made it clear in her invitation that there was no pressure to show up to all or any movie nights. Wonderful! 3 I gratefully accepted her kind
invitation.
4 Although all the women were eager to participate, some said they didn"t see themselves as
optimistic people. "I told them they didn"t have to be cheerful around me all the time. I invited them
because they made me feel happy," she says.
5 In a US study, researchers measured the happiness of 4739 people at regular interval over 20
years. The study found that a person"s happiness depends on the happiness of people they connect with.
Amazingly it also found that a person"s happiness spreads not only between direct friends, but also
among friends of your friends" friends!
A. She is one of my good friends.
B. Research shows such gatherings make sense.
C. Later she had some puzzled reactions to her invitation.
D. And you are on my list.
E. We would chat, eat and watch feel-good movies.
F. I e-mailed her back immediately.
G. She was not satisfied with the women.
