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 to crawl into bed and sleep.
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” affects 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 had to stay awake 40 hours straight.Then,they took tests that measured how quickly they pushed a button when numbers flashed on 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.
People with the long “period 3” gene, by contrast, 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?

February has long been a month of romance.With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.
On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentine's Day, a day named after Valentine who was a priest in third century Rome.When the emperor decided that single men could become better soldiers than those with wives, he didn't allow marriage.
But Valentine continued to perform marriage ceremonies for young lovers in secret.When his actions were discovered, the emperor had him put to death.While in prison, it is said that Valentine fell in love with the daughter of his prison guard.Before his death, he wrote her a letter, which he signed “From your Valentine”, an expression that is still in use today.Valentine died for what he believed in and so was made a Saint(圣者), as well as becoming one of history's most romantic characters.
Nowadays, Valentine's Day is also popular among Chinese young people.Some students are planning to make Valentine's cards for parents, teachers and friends.Others want to hold parties at which they will exchange small gifts and eat heart-shaped cakes.The idea is to have fun and encourage people to share in the spirit of St.Valentine.
