研究發(fā)現(xiàn)，睡眠不足可以靠運(yùn)動來彌補(bǔ)。只要運(yùn)動量達(dá)標(biāo)，即使睡眠質(zhì)量差，也可以抵消不良睡眠帶來的健康風(fēng)險(xiǎn)。

We all know that a healthy life means getting both plenty of exercise and enough goodquality sleep， but reality often gets in the way. A new research indicates that doing enough exercise could make up for some of the unhealthy impacts of bad sleep.

“We found those who had both the poorest sleep quality and who exercised the least were most at risk of death from heart disease and cancer，” says epidemiologist（流行病學(xué)家） BoHuei Huang， from the University of Sydney. “The findings suggest a likely synergistic （協(xié)作的） effect between the two behaviors.”

Participants were grouped into three levels of physical activity and were also given a sleep quality score from 05 based on the amount of shuteye they got， how late they stayed up， snoring and daytime sleepiness.

Those with the highest risk of dying from cancer or heart disease during the study period were those with the worst quality sleep and who didnt have enough exercise. That risk went down for people with poor quality sleep but who did meet the exercise guidelines.

In the case of all forms of cancer， for example， those at the unhealthiest end of the sleep and exercise scale had a 45 percent higher risk of dying from cancer than those with good sleep scores who kept physically active. However， that risk just about disappeared for those who didnt score well on sleep but did score well on physical activity.

For now， its not clear why more exercise might make up for poor sleep， as far as our health goes. “Both behaviors are critical for health but， sadly， our society suffers from both physical inactivity and a poor sleep crisis，” says population health researcher Emmanuel Stamatakis， from the University of Sydney.“Considering that physical activity is perhaps more controllable than sleep， our study offers people more health encouragement to be physically active and provides health professionals with more reasons to prescribe （開處方） physical activity to patients with sleep problems.”

Ⅰ. Difficult sentence in the text

In the case of all forms of cancer， for example， those at the unhealthiest end of the sleep and exercise scale had a 45 percent higher risk of dying from cancer than those with good sleep scores who kept physically active. 以各種癌癥為例，那些睡眠質(zhì)量最差、運(yùn)動量最低的人死于癌癥的風(fēng)險(xiǎn)比那些睡眠質(zhì)量好并堅(jiān)持運(yùn)動的人要高出45%。

【點(diǎn)石成金】本句是一個主從復(fù)合句，句中In the case of all forms of cancer為介詞短語作狀語，who引導(dǎo)定語從句，修飾先行詞those。
