Question

6．Sitting too much is now listed with smoking and junk food as a bad habit that increases your risk of heart disease．
New Australian research shows that half-an-hour in the gym will not make up for the waist-expanding damage caused by spending the rest of the day sitting．
But the good news is that doing chores（家務(wù)雜事）in the house or gently walking around the office while on the phone might be enough to keep you fit．
The study joins the growing body of evidence suggesting too much sitting might undo（消除）the benefits of exercise．
The study measured the intensity（強度）of physical activities in 168 subjects over seven days．It found that，regardless of how much exercise they did or their total sitting time，those who took more breaks from sitting had lower risk of thick waists and lower levels of blood lipids（脂肪）．
"Higher levels of blood lipids have been linked to a heightened risk of heart disease，"principal researcher Genevieve Healy of the University of Queensland said．"What the study shows is that there are benefits in just getting up regularly and interrupting your sitting time．"
Researchers behind the Stand Up Australia project have written to the Rudd Government requesting $3.5 million for a two-year study into the impact how long sitting offects health and productivity of workers．The study would also develop and test strategies for reducing sitting time on the job．
The latest study builds on work that is shifting the health promotion focus from purposeful exercise，such as running，to lower intensity activities throughout the day．
The Australian research has been backed up by US studies．
"To hold a body that weighs 77 kilograms upright takes a fair amount of energy from muscles，"said Professor Marc Hamilton from the University of Missouri．"There is a large amount of energy associated with standing every day that cannot easily be replaced by 30 to 60 minutes in the gym．"

解答 ADCB
60．A  根據(jù)文章第五段的"those who took more breaks from sitting had lower risk of thick waists and lower level of blood lipids（類脂）．"可知久坐后要站起來休息一下對健康有益處，故A正確．
61．D 根據(jù)"…work that is shifting the health promotion focus from purposeful exercise …"可知答案為 D
62．C 最后一段To hold a body that weighs 77 kilograms upright takes a fair amount of energy from muscles，"說明站立會消耗能量，為文章論點提供了數(shù)據(jù)依據(jù)．
63．B 文章主要通過說明久坐的危害和站立的好處提醒人們在久坐時要定時站立起來走動，故用Your Office Chair Is Killing you作為標(biāo)題更準(zhǔn)確醒目，故答案為B．
