做語法和改錯題時多喝咖啡！
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 up in 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 consumed low 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——每天咖啡攝入量低於半杯——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爲一頁的文章，讓他們找出並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。
In a second study, researchers repeated the same experiment with 38 college students who consumed higher levels of caffeine each day. The java junkies typically had at least 300 milligrams of caffeine daily.
在第二個試驗中，研究人員還是以同樣的方法對38名每天會攝入高劑量咖啡因的學生做了測試。這些咖啡控們每天至少攝入300毫克咖啡因。
The low-caffeine crowd was best at finding and correcting these grammatical goofs at 200 milligrams of caffeine. But it took more in the highly caffeinated -- 400 milligrams -- to achieve the highest detection rates.
不太喝咖啡的那一組學生在喝入200毫克咖啡因後找到和更正語法錯誤的能力最佳，而攝入400毫克咖啡因時，他們找出文中錯誤的檢測能力是最強的。
Interestingly, caffeine didn't affect the students' skill at finding and correcting misspelled words. And it had no effect on noticing mistakes in words that sound alike, such as weather and whether or seams and seems.
有趣的是，咖啡因並沒有對學生們找到和更正拼錯單詞的能力造成影響。對於發現weather和whether、seams和seems這樣發音類似的詞也無影響。
"Individuals who habitually consume caffeine on a daily basis are less likely to benefit from caffeine's performance advantages without upping the dose," Brunye says.
“而平時習慣每天喝咖啡的人除非加大劑量，否則獲益無多。”Brunye說。
