Exams can be stressful and everyone looks for a way to make those scores go up.
考试的时候会很紧张，每个人都想得高分。
Wouldn't it be relieving to know that the answer lies in gum?
如果你知道，得高分的关键在于口香糖，惊不惊喜？意不意外？
Yes, that small chewy fruity piece of gum is your key to success. So sit down, grab a stick of gum and chew.
没错啦，这块小小的、软软的水果味口香糖就是你成功的关键啦。所以，请坐下，拿出一支口香糖开嚼。
In the scientific journal Appetite, a study by Professor Onyper shows that if you chew gum before a test,
在科学期刊《Appetite》中，奥尼珀尔教授的一项研究表明，在考试前嚼口香糖，
your performance will increase slightly, as opposed to testing without gum.
和考试不嚼口香糖相比，你的成绩会有稍微的提高。
224 St. Lawrence University undergraduates were tested and divided into three groups:
对224名圣劳伦斯大学的本科生进行测试，将他们分成三组：
chewing gum before and during the test, chewing gum for five minutes before the test and not chewing gum at all.
在考试前和考试期间嚼口香糖、开始前五分钟嚼口香糖以及完全不嚼口香糖。
Results showed that those who chewed gum before the test scored best
结果显示那些在考试前嚼口香糖的学生得分最佳
but their scores levered out to normal after an average of 20 minutes.
但是他们的分数在平均20分钟之后就又降回了正常水平。
Scores were best right after chewing the gum.
考试的成绩恰好在嚼完口香糖后是最好的。
Professor Onyper stated that chewing gum led to a significant increase in working memory and overall, in cognitive function.
奥尼珀尔教授表示嚼口香糖能够显著提高工作记忆，总的来说，是提高认知能力。
While the results were statistically significant, they were described by Onyper as showing a difference of two to three words.
虽然考试结果从数据上来看是很显著的，但是奥尼珀尔教授将其描述为两三句之间的差别。
It must be noted that chewing gum during the test did not improve any performance,
应该注意到的是，在考试期间嚼口香糖并没能提高成绩，
as it may have taken away from the function of a brain.
其效果或许是被大脑功能带走了。
Chewing the gum during the tests distracts the brain from the test at hand,
考试时嚼口香糖会让大脑分神，
though Professor Onyper's study does show that gum chewing improves performance.
虽然奥尼珀尔教授的研究确实表明嚼口香糖能够提高分数。
There is only speculation and theories as to why.
其中原因仅有一些推测和理论。
Initially, some have thought that the rise in glucose from the gum caused better performance
起初，有人认为口香糖中葡萄糖含量导致成绩提升，
but this theory has been disproven as sugar-free gum gave the same results.
但是这个理论被证明是错的，因为无糖口香糖也得出了同样的结果。
Mastication-induced arousal increase in blood flow to the brain caused by chewing was another theory as it increased awareness.
在流入大脑的血流中，咀嚼导致的刺激被认为是另一种解释理论，因为咀嚼能增加意识。
Another study done by Coventry University discovered that mint flavored gum significantly decrease sleepiness of students.
考文垂大学的另一项研究发现薄荷口味的口香糖能够显著降低学生的困意。
A pupil graphic sleepiness test was given to the students and showed that they were less exhausted while chewing the gum.
一项对学生困意的测试表明在学生们嚼口香糖时，他们就没那么困了。
This would give quite an advantage to those chewing mint gums over those not chewing them at all.
这是那些嚼薄荷口香糖的人之于那些完全不吃口香糖人的优势。
Do you believe that chewing gum helps performance during tests? Are you willing to give it a go?
你相信嚼口香糖能够提高分数么？你要不要试一下？
