Every hour spent in watching TV, DVDs and videos as an adult reduces lifespan by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.
The research shows that a sedentary（久坐的） lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.
The researchers set out to calculate the overall risk to lifespan from watching television. Their research involved more than 11,000 people over the age of 25.
Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be connected with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."
The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.
But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.
Earlier this year, a separate study suggested the risk of developing diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.
England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."We can learn from the passage that .
| A．whether you watch TV or not has nothing to do with how long you will live |
| B．if an adult watches TV for six hours every day, he will probably die five years earlier |
| C．physical inactivity and obesity won't shorten your life |

| C．Watching TV for two hours a day will increase the risk of illnesses or dying early by 20%. |

People who multitask all the time may be the worst at doing two things at once，a new research suggests.The findings，based on performances and selfevaluations by about 275 college students，indicate that many people multitask not out of a desire to increase productivity，but because they are easily distracted (分心) and can’t focus on one activity.And “those people turn out to be the worst at handling different things，”said David Sanbonmatsu，a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked，how good they thought they were at it，and how sensationseeking (寻求刺激) or impulsive (冲动)they were.They then evaluated the participants’multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly，the scientists said，most people thought they were better than average at multitasking，and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once.But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test.They also were more likely to admit to sensationseeking and impulsive behavior，which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity，but because they’re distractible，and they get sucked into things that are not as important，”Sanbonmatsu said.
Adam Gazzaley，a researcher at the University of California，San Francisco，who was not a member of the research group，said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest，however，why the sensationseekers who multitask the most may enjoy risky distracted driving.“People who are multitasking are generally less sensitive to risky situations.”said Paul Atchley，another researcher not in the group.“This may partly explain why people go in for these situations even though they’re dangerous.”The research led by Sanbonmatsu indicates that people who multitask________.
| A．seek high productivity constantly |
| B．prefer handling different things when getting bored |
| C．are more focused when doing many things at a time |
| D．have the poorest results in doing various things at the same time |

According to Sanbonmatsu，people multitask because of their________.
