Monday.Socially active people who were not easily stressed had a 50 percent lower risk of developing
dementia compared with men and women who were isolated and prone to distress,they reported in the
journal Neurology.
"In the past,studies have shown that chronic distress (长期抑郁) can affect parts of the brain,possibly
leading to dementia," HuiXin Wang of the Karolinska Institute in Sweden,who led the study,said in a
statement."But our findings suggest that having a calm and outgoing personality in combination with a
socially active lifestyle may decrease the risk of developing dementia even further."
An estimated 24 million people worldwide have memory loss,problems with direction and other
symptoms that signal Alzheimer"s disease and other forms of dementia.Researchers believe the number of
people with dementia may quadruple (变为四倍) by 2050,underlining the importance of better
understanding the condition.
The Swedish study involved 506 elderly people who did not have dementia when first examined.The
volunteers were given questionnaires about their personality traits and lifestyles and then tracked for six
years.Over that time,144 people developed dementia with more socially active and less stressed men and women 50 percent less likely to be diagnosed with the condition.
"The good news is,lifestyle factors can be modified as opposed to genetic factors which cannot be
controlled," Wang said."But these are early results,so how exactly mental attitude influences risk for
dementia is not clear."

When you recognize your teen is under stress,how can parents help your teen stay calm before an exam?
Be involved.Parents need to be involved in their teen"s work.1.________What they look for is your
presence-to talk,to cry,or simply to sit with them quietly.Communicate openly with your teen.Encourage
your teen to express her worries and fears,but don"t let them focus on those fears.
Help them get organized.2.________Together,you and your teen can work out a timetable in which
she can study for what she knows will be on the test.
Provide a calm setting.Help your teen set up a quiet place to study and protect his privacy.Give them a nutritious diet.It is important for your teen to eat a healthy,balanced diet during exam times to focus and do her best.3.________If this happens,encourage your teen to eat light meals or sandwiches.A healthy diet,
rather than junk food,is best for reducing stress.
4. ________Persuade your teenager to get some sleep and/or do something active when she needs a real break from studying.Making time for relaxation,fun,and exercise are all important in reducing stress.Help your teen balance her time so that she will feel comfortable taking time out from studying to spend
time with friends or rest.
Show a positive attitude.5.________Your panic,anxiety and blame contribute to your teen"s pressure.Make your teen feel accepted and valued for her efforts.Most importantly,reassure your teen that things
will be all right,no matter what the results are.
B. Exam stress can make some teens lose their appetite.

All parents have skyhigh hopes for their children.We want them to be confident and content.What can parents do to help their kids grow up to lead happy lives? Experts advise:
1.Helping them find their talents.In order to succeed,children need to feel they’re good at
something.So expose your children to as many interests as possible,then let them choose those they like best.
2.Applauding their achievements. A study found that students whose parents paid attention to
their abilities were far more likely to do well in school-and in life-than students whose parents didn’t show such support.So celebrate your kids’achievements,no matter how small they are.
3.Praising their efforts. Kids won’t always come out on top.Still,they deserve kudos (赞誉) for trying their best.Tenyearold April Cutler,for example,has had trouble with math since second grade.
"She usually gets C’s on her report card,but last year she was determined to get A’s and worked hard at it," says her mom.“When the first grading period ended,April was disappointed when she got a B
minus in math," Lueille continues.“But my husband and I told her we were very proud that she’d
improved.That inspired her to try even harder.She got a B plus for the next period !"
4.Letting them make decisions and mistakes.Making his/her own decisions increases a child’s
sense of control and builds his/her selfesteem (自尊心).And allowing kids to make wrong decisions-so
long as doing so won’t harm them-helps kids learn from their mistakes.
5.Encouraging them to solve their own problems.As they grow,children need practice in
communicating,standing up for themselves and compromising.One of the best places to learn these skills
is at home.So the next time your child runs to you complaining that her brother is blaming her,step back
and let them work it out.

Between 1993 and 1995,Atul Singhal of the Institute of Child Health and his colleagues researched 299 fullterm newborns,each of whom weighed very little for their age.The babies" moms had decided not to breastfeed (用母乳喂养).
2.________The rest received a formula with more nutrients and 28 percent more protein than the standard formula.The growth of all of these children was compared to that of 175 similarly low birthweight babies whose mothers had chosen to breastfeed their children for their first 9 months.3.________They found 83 babies from the normalformula group,70 babies from the extraformula group,and 95 babies from the breast fed group.4.________According to the latest data,children who had received the extra formula had significantly higher blood pressures than those in the other two groups.
Seven human tests have indeed shown that when infants are overfed before being stopped breastfeeding,they have an increased possibility to become fat as youngsters.
No matter how big a child is at birth,he or she will probably reach the same adult

Scientists have shown that teens are more active later at night

teens areprobably staying up later for whatever reasons.“The researchers measured the presence of the
sleeppromoting hormone (荷尔蒙) in teenagers’ saliva (唾液) at different time of the day.They learned
that the hormone levels rise later at night than they do in children and adults-and remain at a higher level
later in the morning.Measuring the hormone in the saliva is a good way to show that most teens have
sleep problems,but changing school schedules isn’t t

changing school schedules would say that it would only cause teens to stay up and wake up later,thus
leaving them with the same problem.
The biggest problem schools would come across from changing their schedules would be the after
school and job conflicts students and teachers would meet.“Teachers reported that students were more
alert,and research showed that afterschool sports and jobs would suffer.Students in that area might have been able to deal with less time for jobs and sports somehow,but some of them

And the under25s who have watched color TV all their lives tend to have colorful adventures in_the_
land_of_nod.
Research from the first half of the 20th century,especially in the 1930s and 1950s,suggested that most
dreams are in black and white.
But results from tests in the 1960s and later suggested that up to 80 per cent of dreams contain some
colors.
Since this period marked the transition (过渡) from blackandwhite films and TV to widespread
Technicolor (彩色印片法),an obvious explanation was that television was influencing dreams,but
differences between the studies prevented the researchers from drawing any firm conclusions.
Later studies asked subjects (实验对象) to complete dream diaries immediately they woke up,but
the earlier research used questionnaires completed in the middle of the day,so the subjects might have
simply forgotten color elements in their dreams and assumed they were grey.
To solve the pr

over 55,to answer a questionnaire on the color of their dreams and their childhood exposure (暴露) to
films and TV.
The subjects then recorded different aspects of their dreams in a diary every morning.
She found there was no significant difference between results drawn from the questionnaires and the
dream diaries.
She then analyzed data to find out whether an early exposure to blackandwhite TV or films could still
have a lasting effect on her subjects"dreams,40 years later.
Less than five per cent of the under25s"dreams were black and white.But the over55s who had access
to blackandwhite media in their younger days reported dreaming in black and white roughly a quarter of
the time.
Murzyn said,"There could be a critical period in our childhood when watching films has a big influence
on the way dreams are formed." People"s attention might be heightened during the time they are watching
TV or films.
