工時長、站立時間多
A new study in The Lancet has discovered five jobs that put people at risk of dementia.
刊載在醫學期刊《刺胳針》（The Lancet）的一項新研究發現，有五種工作會使人們面臨失智症的風險。
discover(v.)發現，discovery(n.)發現、探索at risk of(phr.)有⋯的風險，risk(n.)風險(v.)冒⋯的風險，risky(adj.)有風險的put sb.(sth.) at risk of...把某人(某事)置於⋯的風險job(n.)工作=occupation=profession
These include salesperson, nurse or care assistant, retail worker, farmer, and animal producer.

include(v.)包括，inclusive(adj.)包含的、包括的include反義字：exclude(v.)排除在外、不包含retail(n.)零售
The study found that people who worked these jobs between the ages of 33 and 65 had a 72% higher chance of dementia and other brain diseases in their 70s.
研究發現，在33歲到65歲之間從事這些工作的人，在70幾歲時患失智症和其他腦部疾病的機會增加了72％。
find(v.)發現=revealchance(n.)機會、可能性=likelihoodin one’s 20s(30s)某人在20(30)幾歲時
These results are surprising because all five jobs require a lot of physical work.
這些研究結果令人驚訝，因為這五種工作都需要進行大量的體力勞動。
surprising(adj.)令人驚訝的，raise eyebrows(phr.)使人驚訝require(v.)需要，requirement(n.)需要；involve(v.)牽涉、干涉、需要physical(adj.)體力的、生理的、身體的，PE class=physical education class體育課mental(adj.)心理上的
For years, scientists thought that jobs like these protected the brain from health problems.
多年來，科學家們以為這類工作可以保護大腦免受健康問題的困擾。
protect(v.)保護，protect A from...保護A免於⋯；keep away from...遠離⋯
However, this study’s results are completely different.
然而，這項研究的結果卻完全不同。
however(adv.)然而=nonetheless=neverthelesscompletely(adv.)完全地=totally=entirely
Scientists now believe that these five jobs’ long working hours, many hours of standing, and fewer breaks may not only affect workers’ bodies but also their minds.
科學家們現在認為，這五種工作的工時長、站立時間多、休息時間少，可能不僅影響工作者的身體，還會影響他們的大腦。
not only...but also...不僅⋯還⋯mind(n.)大腦、頭腦
Therefore, other, less physical jobs, like office worker or teacher, may be healthier for people’s brains because they give more time for workers to rest.
因此，其他體力消耗較少的工作，如上班族或教師，對大腦的健康可能更有利，因為它們給予工作者更多的休息時間。
therefore(adv.)因此=consequently=accordingly=hencemay be可能是⋯；maybe(adv.)可能、或許
Right now, around seven million Americans and one million Britons are living with dementia.
目前，約有700萬名美國人和100萬名英國人患有失智症。
right now=for the time beingaround(adv.)大約=approximatelylive with+疾病=suffer from+疾病=患有⋯疾病
Scientists hope that this study’s results can lead to changes in the ways people work to help protect their brain health later in life.
科學家希望這項研究的結果能夠改變人們的工作方式，以幫助保護他們日後的大腦健康。
lead to導致、引起=result in=cause
