In a new look at the impact of long-time sitting behavior on health, a new study links time watching television to an increased risk of death. One of the most surprising findings is that it isn’t just couch potatoes who were affected. Even for people who exercised regularly, the risk of death went up the longer they were in front of the TV. The problem was the long periods of time spent sitting still.
Australian researchers who tracked 8,800 people for an average of six years found that those who said they watched TV for more than four hours a day were 46% more likely to die of any cause and 80% more likely to die of cardiovascular (心血管的) disease than people who reported spending less than two hours a day in front of TV.
Time spent in front of TVs and computers and videogames has come under fire in studies in recent years for contributing to a spread of obesity in the US and around the world. But typically the resulting public-health message urges children and adults to put down the Xbox controller and remote and get on a treadmill (跑步机) or a soccer field.
The Australian study offers a different view. “It’s not the sweaty type of exercise we’re losing,” says David Dunstan, a researcher at Baker IDI Heart and Diabetes Institute, Melbourne, who led the study. “It’s the incidental moving around, standing up and using muscles. That doesn’t happen when we are plunked on a couch in front of a television.”
Indeed, participants in the study reported getting between 30 and 45 minutes of exercise a day, on average.The results are supported by a new field of research that shows how long periods of inactivity can affect the body’s processing of fats and other substances that contribute to heart risk. And they suggest that people can help decrease such risk simply by avoiding extended periods of sitting.”
Keeping such processes working more effectively doesn’t require constant intense exercise, but consciously adding more routine movement to your life might help, doctors say. “Just standing is better than sitting,” says Gerard Fletcher, a cardiologist at Mayo Clinic, Jacksonville, Fla., who works standing up at his computer. “When you stand up, you shuffle around a little bit and use muscles not required when you are sitting or lying down.”
Simple strategies for increasing activity include combining household chores such as folding laundry with TV-watching time or getting up to change a TV channel rather than using a remote control. The report, published Tuesday in the American Heart Association journal Circulation, focuses on TV watching in part because it is the main leisure-time activity in many countries, researchers said, especially in the US.
1.One misunderstanding people might have is that ________.
A. the radiation from TV may badly affect your sight
B. TV programs can broaden your horizons effectively
C. watching TV very long is a good way to kill time
D. regular exercise can minimize the side effect of watching TV
2.What is new about the discovery of the Australian study?
A. Remote control shouldn’t be used when people watch TV.
B. People who watch TV too long should take more physical exercise.
C. Sitting too long in front of TV will lead to high risk of heart attack.
D. Long-time sitting is bad for all people including those who exercise regularly.
3.According to the Australian study, how can the risk of death be reduced when people watch TV?
A. By increasing simple movement.
B. By totally avoiding watching TV.
C. By taking some medicine.
D. By increasing sweaty type of exercise.

I had looked forward to this day for a long time．Finally I, Kirsty Sturart, would stand on the top of Mont Blanc, the highest mountain in Europe．Although I climbed often in my native Scotland, this was my first trip to the Alps．My companions—Jean Pierre Barton, Maurice Gautier, and Mary Sargent—and I left our camp early and planned to reach the top by late morning．
As we neared the top, large clouds gathered and it began to snow．We found shelter and decided to wait for the snow to stop．After three hours, however, we decided to go back and try again the next day．We started down the mountain in the thick snow．Jean-Pierre forgot his sunglasses and went back to look for them．As he was returning to us, he started to fall．
His fall started an avalanche（雪崩） and it was falling towards us! I was swept away by the heavy snow. Jean-Pierre hurried down to me．“Are you OK?” he asked．
“I think I broke my leg,” I answered．
“I’d better radio for help!” he said．“Where are the others?” We couldn’t see Maurice or Mary anywhere．
Jean-Pierre called the emergency radio number, and the police said they would send help right away．It seemed like hours, but only minutes later we heard the welcome sound of a helicopter． The helicopter couldn’t land on the mountainside, so they lowered two men, two dogs, and a stretcher（担架）．One man ran to me, but I told him to search for the others．The dogs were trained for avalanche rescue and soon began to dig crazily in the snow．
Bernardo, the lead dog, found Mary’s scarf and led the rescuers to her．Maurice was nearby．The men gave us hot drinks and warm blankets and then prepared to lift us into the helicopter．Two men inside the helicopter pulled us up with the ropes．I went first on the stretcher．
Once we were safely inside, the helicopter flew to the hospital in Chamonix．Our poor rescuers and their dogs had to climb all the way back down the mountain．Later we would find these brave men and thank them for saving our lives．
1.What prevented the climbers from reaching the top?
A．The terrible weather．
B．The loss of the sunglasses．
C．The injury of the team members．
D．The unexpected height of the mountain．
2.How did the writer break his leg?
A．The road was covered with snow．
B．His companion knocked into him．
C．The heavy clouds blocked his view．
D．The avalanche caused a fall for him．
3.How did the writer feel while waiting for help?
A．Anxious． B．Crazy． C．Sorry． D．Annoyed．
4.What do we learn from the passage?
A．Mary was the leader of the team．
B．The team was upset about their failure．
C．It was several hours before the rescue team arrived ．
D．The writer was excited thinking of climbing Mount Blanc．
