You probably count on your daily jolt of caffeine to wake up your brain and stay sharp all day long. But downing that coffee, tea, cola, or chocolate bar may be giving you a leg upin another unexpected way: It can improve your proofreading skills, according to a new study.
也許你現在每天要靠咖啡來醒腦、醒神。但其實咖啡、茶、可樂和巧克力棒還能在其他方面給你意想不到的幫助：一項最新研究表示，它能幫你提高你的校正能力。

In the study, published in the Journal of Experimental Psychology: Applied, researchers asked 36 college students who consumedlow levels of caffeine -- about a half-cup of coffee a day -- to do a "language task." The students were given 5 minutes to read a one-page news story, and needed to identify and correct as many spelling and grammatical mistakes as they found in that time.
在《實驗心理學期刊》上發表的文章：研究者讓36名對咖啡攝入程度較低的大學生——每天咖啡攝入量低于半杯——做一個“語言測試”。給這些受測試者5分鐘時間來讀一篇長度約為一頁的文章，讓他們找出并更正文內的拼寫和語法錯誤。

Forty-five minutes before taking the proofreading test, students were randomly given a capsule containing one of four doses of caffeine: none, 100 milligrams, 200 milligrams , or 400 milligrams.
在校對測驗開始前45分鐘，有四種劑量的咖啡因膠囊，分別是不含咖啡因、100毫克、200毫克、和400毫克，這些膠囊讓參加測驗的學生任意領取一枚。
