托福閱讀背景材料 大笑有益心臟

　　小編為各位考生整理了托福閱讀機(jī)經(jīng)背景材料：大笑有益心臟，供考生們參考使用，希望考生平時多積累。

　　Laughter is good for the heart because it prolongs life while depression increases the risk of an early death, according to two new studies.

　　據(jù)兩份最新研究表明，大笑有益心臟健康，能延年益壽; 相反，憂郁增加早死的危險。

　　A good bout of laughter every day provides similar cardiovascular benefits as exercise because it stimulates the blood flow, said Michael Miller, who headed one research team at the University of Maryland.

　　其中一項(xiàng)研究的負(fù)責(zé)人、美國馬里蘭大學(xué)的邁克爾?米勒表示，堅(jiān)持每天開懷大笑，能促進(jìn)血液流動，像鍛煉身體一樣，提高心血管健康。

　　On the other hand, depression -- or the lack of laughter -- is often linked to unhealthy habits such as smoking and drug addiction and increases the risk of death by 44 percent, said Wein Jiang, who led a study of 1,000 heart patients for the University of North Carolina.

　　另一方面，北卡羅萊納大學(xué)的Wein Jiang負(fù)責(zé)的另一項(xiàng)研究，研究了1000個心臟病患者則表明，沮喪或者少笑常常與不健康習(xí)慣聯(lián)系在一起。比如，吸煙，吸毒等。同時，死亡的危險增加44%。

　　Miller said laughter produced a "magnitude of change ... in the endothelium ... similar to the benefit we might see with aerobic activity, but without the aches, pains and muscle tension associated with exercise"

　　Miller稱笑會在心內(nèi)膜內(nèi)引起很大的變化，其功效類似于我們進(jìn)行的有氧運(yùn)動，而且避免了因?yàn)殄憻挾弁椿蚣∪饩o張等不良影響。

　　While laughter should not replace exercise, he said, "We do recommend that you try to laugh on a regular basis. Thirty minutes of exercise three times a week, and 15 minutes of laughter on a daily basis is probably good for the vascular system."

　　他還表示，笑并不能代替鍛煉。我們強(qiáng)烈建議每天都笑笑。一周堅(jiān)持三次半小時以上的運(yùn)動，每天笑15分鐘，這樣會對人們的脈管體統(tǒng)大有裨益?！?

　　cardiovascular [,kɑ:di?u'v?skjul?] adj. 心血管的
