Here's a new warning from health experts: Sitting is deadly. Scientists are increasingly warning that sitting for prolonged periods — even if you also exercise regularly — could be　 1 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 　2　 .

Research is preliminary, but several studies　 3 people who spend most of their days sitting are more likely to be fat, have a heart attack or even die.

In an editorial　 4 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　 5 activity to highlight the dangers of sitting.

While health officials have issued guidelines　 6 minimum amounts of physical activity, they haven't suggested people try to limit how much time they spend in a seated 　7 .

"After four hours of sitting, the body starts to send　 8 signals," Ekblom-Bak said. She explained that genes regulating the amount of glucoseand fat in the 　9 start to shut down.

Even for people who 　10　 , spending long stretches 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 — 　11 still spend a lot of time sitting — might get more benefit if that exercise were spread across the day,　 12 in a single bout.

That wasn't 　13 news for Aytekin Can, 31, who works at a London financial company, and spends most of his days sitting 　 14　 a computer. Several evenings a week, Can also teaches jiu jitsu, a Japanese martial art 15 wrestling, and also does Thai boxing.

"I'm sure there are some detrimental　 16 of staying still for too long, but I hope that being 　17 when I can helps," he said. "I wouldn't want to think the sitting could be　 18 dangerous."

Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat　 19 had a higher death risk, independently of whether or not they exercised.

Figures from a US 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　 20 just how much sitting is dangerous, and what might be possible to offset those effects.

　　     The manager waved his hand towards the chair on the other side of　　 the desk and told Henry 1. "I'm waiting for a long-distance call from　　 Manchester," he explained. The telephone rang just as he spoke.The　　 manager 2 the receiver (受话器) and for some minutes spoke rapidly and　　 impatiently into the telephone. Henry waited, rather regretting that　　 his interview (会见), which he had been dreading for days, had not　　 begun at once. When at last the manager had finished, a secretary came　　 in with 3 letters."I really won't keep you waiting4 ,"said the manager　　 apologetically, as he picked up the first letter and began to read　　 it. "But these 5 the next post."

　　     Henry passed the time by examining the manager's office in some　　 detail (仔仔细细地). On his right there was a large window, heavily　　 curtained, with a view of the factory yard.Henry could see two workmen　　 6 a trolley (手推车) across it towards a shed at the far end.7 the　　 window there were three chairs, arranged around a long, low table, 8　　 stood a jug of water and some glasses. To Henry's left there was a　　 bookcase, which covered the greater part of one wall.The shelves were　　 empty 9 reference books, a pile of technical journals (杂志), which　　 10 they might at any moment slip off the shelf and fall to the　　 ground, on the top shelf, standing by itself and looking rather 11 in　　 the manager's office, a child's plastic toy. Henry 12 it came to be　　 there.

　　     The most impressive (给人印象深的) piece of furniture in the room　　 was the manager's desk. Everything on its spacious (宽敞的) polished(擦亮) top was arranged with great neatness (整洁).13 there were two　　 metal trays (浅盘), one marked IN, the other marked OUT.In the latter　　 (后者) the manager dropped the letters which he had just signed.Henry　　 had finished his survey (环视) of the room when the manager signed the　　 last letter and threw it into the tray 14 ."That's the lot,"he said,　　 as he rang the bell for his secretary to come in and take the letters　　 away. Then he 15 his glasses and rubbed his eye."Now let me see," he　　 said."You've come about our advertisement for a clerk(职员) in the　　 accounts section (会计科), haven't you?" Henry nodded. His interview　　 had begun.

Lisa, 14, smiled as she turned to see who it was.

But the smile   1   . For it was not a friend who had   2   her, but a dense cloud of angry bees.

Lisa held her breath. She made up her mind not to panic. She quickened her pace. But the dark cloud still    3   her.

And suddenly they were swarming（成群地飞）all over her,    4   in her hair, on her thin summer blouse and bare（赤裸的）arms.

Then,    5   to control herself, Lisa threw up her hands to   6   her face and screamed（尖叫）for help. But her screams on the main country road to Odiham, Hampshire, went unheeded（无人留意的） by passers-by as raging bees stung（叮）her again and again. Car after car   7   by, but nobody stopped to    8   .

Then suddenly there was a screech（刹车声）of tires. Lisa   9   a gentle hand on her arm and a man's voice firmly, “Quick, into the car!” It was several minutes   10   she realized that it was a police patrol（巡逻）car.

But the   11   was not over yet. For the bees were still raging. And the police were uncertain what to do.

Learning that Lisa's home was only half a mile away, the driver   12   it with siren（报警器）blaring（喇叭声）. When the patrol car stopped   13   Lisa's home, she was still   14   , “They’re biting me. ”

Only after the girl's mother had rushed her to the   15   and put her fully-clothed   16   a cold shower was the last bee dislodged（移走）.

Then while Lisa stood sobbing, the mother and police officer Richard Panton removed 18 stings. A dozen more were later removed by a family   17   , who also gave Lisa injection(注射).

Lisa said, “I was very    18    that the police came by because nobody else   19   . And the doctor told me I could have been   20   if many more bees had stung me. ”
