Some people can stay up all night and still get work done the next day. I’m not one of them. After a night without enough sleep, I feel bad-tempered. I have trouble remembering things. And all I want to do is go to bed.
How do you feel after you’ve stayed up late to finish schoolwork or the day after an overnight party? Scientists now say that your answers to these questions may depend on your genes.
New research suggests that a gene called “period 3” influences how well you function without sleep. The “period 3” gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you.
Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of “period 3”. Study participants (参与者) had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed (闪过) on a screen and how well they could remember lists of numbers.
Results showed that the people with the short form of “period 3” performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning.
After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests (those with the short form of “period 3”) took about 18 minutes to nod off.
While people with the long “period 3” gene fell asleep in just 8 minutes. They also spent more time on deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.
I think I must have the long form of “period 3”. What about you?英文翻译

有些人可以熬夜通宵和所做的工作仍然得到第二天.我不是其中之一.经过一夜没有足够的睡眠,我觉得坏脾气.我有麻烦记住的东西.和所有我想要做的是上床睡觉.
如何你觉得你熬夜晚过夜后党完成学业或一天吗?现在科学家们说,这些问题的答案可能取决于你的基因.
新的研究表明,一个名为“3期”基因影响如何,你没有睡眠功能.“期间3”基因有两种形式：短期和长期的.每个人都有基因的两个副本.所以,你可能有两个多头,两个短裤,或每一个.你的特定组合,取决于你的父母传递给你.
在英国萨里大学的科学家研究了24人副本或者两短两长“3期”.研究参与者（参与者）直保持清醒40小时.然后,他们把测试,衡量他们如何迅速按下按钮,当数字闪现在屏幕上,以及他们如何能记得的数字列表（闪过）.
结果表明,与短形式的“3期”人民执行长形式的人做这些测试比好得多.在这两个群体,人们在清晨进行的最糟糕的.
经过第一轮实验中,参与者最终被允许睡觉.组中进行测试（“3期”的缩写形式）的人参加了约18分钟,打瞌睡.
而长期“期间3”基因的人睡着了,在短短的8分钟.他们还花更多的时间,深睡眠.这表明,与该基因的长形的人需要更多和更深的睡眠,以保持他们的大脑工作在最佳状态.
我想我必须有“期间”长形式.你怎么样

. 有些人可以熬夜，第二天仍可以继续工作。我不是这样的人。一个晚上没有足够的睡眠，我就感到烦躁，记忆力也减退了，我唯一想做的事情就是去睡觉。
你在熬夜完成作业或参加了一个通宵的聚会后感觉如何？科学家们现在认为，你对这个问题给出的答案可能取决于你的基因。
新的研究表明，一个称为“3期”的基因影响了一个人对熬夜所反应的程度 。“3期”的基因有两种：短期形式和长期形式。每个人都有两个基因的拷贝。所以，你可能有两个长期，两个短期，或长期短期各有一个。你的特殊的结合，取决于你的父母遗传给你的是什么。英国塞瑞大学的科学家研究了24个有两个短期形式 两个长期形式或短期长期各有一个副本的“3期”的人。参与研究者必须保持40个小时连续不睡觉，然后，他们做测试，当数字在屏幕上闪过的时候，看他们能多快速的按下按钮，并能记住那一连串的数字。
结果表明，短期形式的“3期”的人表现的要比长期形式的“3期”人好得多。在这两组人当中，表现最差的是在清晨。第一轮实验后，让参与测试的人去睡觉 。测试中表现好的那组人（那些人是短期形式的“3期”人）只打了大约18分钟的盹。而那些长期形式的“3期”人8分钟之后就睡着了，而且熟睡了很长一段时间。这表明，有长期形式“3期”基因的人需要更多和更深的睡眠来保持大脑的工作状态。
我想我一定是长期形成的“3期”。你呢？
