Rae and Bruce Hostetler not only work very hard，they also relax just as well.Numerous vacations help the couple to maintain their health and emotional well?being??and it’s no surprise to health care professionals.
“Rest，relaxation，and stress reduction are very important for people’s well?being and health.This can be accomplished through daily activities，such as exercise and meditation，but vacation is an important part of this as well，” said primary care physician Natasha Withers from One Medical Group in New York.Withers lists a decreased risk of heart disease and improved reaction time as some of the benefits from taking some time off.“We also know that the mind is very powerful and can help with healing，so a rested，relaxed mind is able to help the body heal better，” said Withers.
Psychologists confirm the value of vacations for the mind.“The impact that taking a vacation has on one’s mental health is great，” said Francine Lederer，a clinical psychologist in Los Angeles who specializes in stress and relationship management.“Most people have better life perspective and are more motivated to achieve their goals after a vacation，even if it is a 24?hour time?out.” The trips could be good for their health，good for their family and good for their businesses.
The online travel agency Expedia conducted a survey about vacation time in 2010，and according to their data the average American earned 18 vacation days—but only used 14 of them.France topped the list，with the average worker earning 37 vacation days and using all but two of them.Americans’ responses may not be surprising in a culture where long hours on the job often are valued，but that’s not always good for the individual，the family or the employer.
Psychologists have also found that people who don’t take enough time to relax may find it harder to relax in the future.“Without time and opportunity to do this，the nerve connections that produce feelings of calm and peacefulness become weaker，making it actually more difficult to shift into less?stressed states，” Mulhern said.

It can be hard to encourage families of preschoolers to turn off the TV，but there are plenty of high?quality shows that promote learning and positive relationships rather than violence，researchers noted.
“Although clearly kids watch too much，what’s more worrying is that they watch poor quality shows，” said Dr Christakis，the lead researcher on the new study from the University of Washington in Seattle.His former survey of parents of three?to five?year?old children showed the kids often watched violent cartoons and movies that are “totally inappropriate”．
For their study，he and his colleagues randomly divide 565 preschoolers into two groups.In one group，parents recorded notes about kids’ normal TV viewing，without receiving any guidelines to reduce or change those habits.In the other group，researchers made visits and calls and sent monthly newsletters encouraging parents to replace violent TV with educational programming.After six and 12 months，parents reported their kid’s angry，aggressive or anxious behaviors on a questionnaire.At both time points，children in the TV intervention (干预) program had slightly fewer problems than those in the comparison group.Boys in low?income families seemed to benefit most from the change in programming，the researchers found.
“The point is，this is something that is as effective as other things we do to try to guide behavior in children，and it’s fairly simple，” Christakis said.
Another study published in Pediatrics found the more TV kids and teens watched，the more likely they were to have a crime or other problems in society.Children may imitate violence they see—or more time in front of the TV could simply mean less communication with peers and families，and worse performance in school.
The American Academy of Pediatrics recommends kids watch no more than one to two hours of high?quality programming each day.Researchers agreed parents should be mindful of what exactly their young kids are watching on TV as well.“It’s not just about turning the TV off，it’s about changing the channel，” Christakis said.
1.What is the positive effect of high?quality TV shows on kids?
A．Good learning results and relationships.
B．Being affected by violence.
C．Spending less time on TV programming.
D．Encouraging them to turn on the TV.
2.For Christakis，what is more concerning?
A．Kids watching too much TV.
B．TV shows being of poor quality.
C．Kids watching too many cartoons.
D．Parents receiving no guidelines.
3.We can learn from the survey mentioned in Para.3 that________.
A．Children don’t like being disturbed while watching TV
B．Preschoolers seems to like newsletters more than TV
C．Poor children prefer to watch educational programming
D．Kids watching high?quality programs have fewer problems
4.Christakis thought the effect of educational programming on children’s behaviour was________.
A．unclear B．slight
C．obvious D．great
5.According to the researchers，________.
A．getting preschoolers away from TV is difficult
B．shows on TV in America are full of violence
