考研英語閱讀:呼吸霧霾會引發(fā)中風(fēng)

　　導(dǎo)語：近年來，國內(nèi)多地頻頻遭遇霧霾天氣襲擊，民生健康問題引擔(dān)憂。根據(jù)最新研究顯示，呼吸霧霾空氣可能會讓你的動脈硬化速度加快。以下是小編為大家精心整理的英語閱讀資料，歡迎大家閱讀參考!

　　Breathing particulate-laden (aka smoggy) air may be hardening your arteries faster than normal, according to research published recently in PLOS Medicine. While everyones’ arteries harden gradually with age, a team of researchers led by epidemiologist Sara Adar of the University of Michigan School of Public Health discovered that higher concentrations of fine particulate air pollution were linked to a faster thickening of the inner two layers of the carotid artery.

　　根據(jù)近日發(fā)表在《公共科學(xué)圖書館•醫(yī)學(xué)》雜志上的研究，呼吸含大量顆粒物的(霧霾)空氣可能會讓你的動脈硬化速度加快。盡管每個人的動脈都會隨著年齡增大而逐漸硬化，但密歇根大學(xué)公共衛(wèi)生學(xué)院的'流行病學(xué)家薩拉•阿達(dá)領(lǐng)導(dǎo)的研究團(tuán)隊發(fā)現(xiàn)，空氣中的細(xì)微顆粒污染物濃度升高與頸動脈內(nèi)膜和中膜增厚加快有關(guān)。

　　Because the carotid artery feeds blood to the neck, head, and brain, a narrowing or blockage there can trigger strokes. And general atherosclerosis, or hardening of the arteries, is a major risk factor for cardiovascular disease, heart attack, and heart failure.

　　由于頸動脈要向頸部、頭部和大腦供血，頸動脈變窄或堵塞可能會引發(fā)中風(fēng)。通常動脈硬化是冠心病、心臟病發(fā)作和心力衰竭的主要風(fēng)險因素。

　　Past research has demonstrated that the rates of stroke and heart attack are higher in polluted areas, but experts haven’t been able to pinpoint just how polluted air is raising peoples’ risk for heart attack or stroke. This time, Adar’s team, along with Joel Kaufman, professor of environmental and occupational health sciences and medicine at the University of Washington, was able to directly measure carotid artery thickness and link it to air pollution data.
