LONDON—Here’s a new warning from health experts：Sitting is deadly.
Scientists are increasingly warning that sitting for long periods—even if you also exercise regularly—could be bad for your health.And it doesn’t matter where the sitting takes place—at the office，at school，in the car or before a computer or TV—just the overall number of hours it occurs.Several studies suggest people who spend most of their days sitting are more likely to be fat，have a heart attack or even die.
In an editorial published this week in the British Journal of Sports Medicine，Elin Ekblom?Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define physical activity to highlight the dangers of sitting.
While health officials have issued guidelines recommending minimum amounts of physical activity，they haven’t suggested people try to limit how much time they spend in a seated position.
“After four hours of sitting，the body starts to send harmful signals，”said Ekblom?Bak.She explained that genes regulating(调节) the amount of glucose(葡萄糖) and fat in the body start to shut down.
Even for people who exercise，spending long periods of time sitting at a desk is still harmful.Tim Armstrong，a physical activity expert at the World Health Organization，said people who exercise every day—but still spend a lot of time sitting—might get more benefit if that exercise was spread across the day，rather than in a single bout(一回)．
Still，in a study published in 2009 that tracked more than 17,000 Canadians for about a dozen years，researchers found people who sat more had a higher death risk，whether or not they exercised.
“We don’t have enough evidence yet to say how much sitting is bad，” said Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge，who led the Canadian study.“But it seems the more you can get up and interrupt this sedentary behavior，the better.”
Figures from a U．S. survey in 2003?2004 found Americans spend more than half their time sitting，from working at their desks to sitting in cars.
Experts said more research is needed to figure out just how much sitting is dangerous，and what might be possible to offset those effects.
“People should keep exercising because that has a lot of benefits，” Ekblom?Bak said.“But when they’re in the office，they should try to interrupt sitting as often as possible，” she said.

Eleven-year-old Evan Green doesn’t want to save just one tree－he wants to save a whole rainforest!
In the Redwood City, Calif., a boy started a group called the Red Dragon Conservation Team four years ago to do just that. So far, the team’s members have raised $4,500. That’s enough to purchase and protect more than 16 acres of rainforest in Costa Rica through the Center for Ecosystem survival.
Every year, thousands of square miles of rainforest are destroyed worldwide. Logging（伐木）and farming are mostly likely to blame, scientists say. The loss is terrible news for animals and people. Even though rainforests cover less than 2 percent of the earth, they are home to half the world’s plants and animals. Rainforests also provide water and help control the earth’s climate.
Evan’s work to save the rainforests recently earned him a Barron prize for Young Heroes. The prizes are given to children or teenagers who have made a positive difference in the world. Evan’s goal is “to save enough rainforests to last forever”. He won’t have to do it alone. His actions have already inspired other kids to chip in. One girl asked for donations instead of presents on her birthday. She raised $850. Other kids are starting their own conservation teams.
Evan says everyone can help the planet－even by taking small steps such as recycling. He and his family try to make a difference every day. “We recycle, we try to limit our garbage… we’ve been walking a little more, and we buy local food,” Evan said.
48. How much does it cost to buy and protect an acre of rainforest in Costa Rica?
A. About $4,500. B. About $850. C. About $280. D. About $1,000.
49. The underlined phrase “chip in” in Paragraph 4 probably means “________”.
A. look at B. contribute money
C. ask for birthday presents D. donate gifts
50. What Evan said in the last paragraph suggests that _________.
A. we can all do something to protect the earth
B. actions speak louder than words
C. we should learn to recycle from now on
51. What would be the best title for the passage?
A. Evan Green-a famous teenager B. The Red Dragon Conservation Team
C. Rainforests are being destroyed D. Boy gathers support for rainforests
