How do you feel after you've stayed up late to finish schoolwork? Or the day after a slumber party? Scientists now say that your answers to these questions may depend on your genes.
Genes are stretches of DNA that work like an instruction manual for our cells. Genes tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms. So, for example, certain forms of some genes make your eyes blue. Other versions of those genes make your eyes brown.
In a similar way, new research suggests that a gene called period3 affects how well you function without sleep. The discovery adds to older evidence that period3 helps determine whether you like to stay up late or get up early.
The period3 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 period3. Study participants had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed on a screen and how well they could remember lists of numbers.
Results showed that the people with the short form of period3 performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning. That's the time when truck drivers and other night-shift workers say they have the most trouble concentrating.
After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off.
People with the long period3 gene, by contrast, fell asleep in just 8 minutes. They also spent more time in deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working at top form.
We can know from the passage that genes can not ________.
A. tell our bodies and brains what to do
B. make our eyes blue or brown
C. decide how well you work without sleep
D. ensure whether you’re good at driving
Which of the following statements about the period3 is wrong?
A. It affects whether you like to stay up late or get up early.
B. It comes in two forms: short and long.
C. One has either two longs or two shorts of it.
D. Your parents determine what particular combination you have.
People with the short form of period3__________.
A. need to go to bed early and get up early
B. can work better than the people with long form of period3 without sleep
C. take less time to fall asleep after they stay up late
D. need more and deeper sleep to keep their brains working at top form
What’s the best title of the passage?
A. The Period3 Gene B. The Function of Genes
C. Wake up, Sleepy Gene D. Stay up Late or Get up Early?

For a long time, a boy wondered why his next-desk-pal was always the first in the class, whereas he could only rank the 21st. At home, he asked his mom, “Am I more stupid than other kids? How come I always lag behind? I just can’t come up with an answer.” Mom was aware that her son’s self-respect had been damaged by the ranking system, but she didn’t know what to say to help.
She was tempted (想要) to say that intelligence differs and that yes, her son’s friend really was the smarter boy. But that would have so upset her son. Thank goodness she resisted the temptation to say it.
Her son and his friend went on to high school that year, but despite trying as hard as he could, her son’s friend still outdid him. But she was proud of her boy for his hard work, sincerely proud. It was around this time she decided to take him on a trip to the seaside. On the trip, she at last found an answer for him.
Today her son no longer cares about rankings. He doesn’t have
to, for he himself is now the top of the class – at the top national university he attends. Invited to speak to his old high school, he mentioned a valuable childhood experience: “Once, on a trip to the sea, my mother and I were lying on the beach. She pointed to the sea and said to me: ‘Do you see the seabirds fighting for food out there? When a wave comes near, the little birds rise quickly. The “clumsy” seagulls (海鸥) are far less agile (灵活的) and have to struggle to get away from the wave. But these “clumsy” birds prove to
have the biggest, strongest wings, which open the widest and allow the bird to travel the furthest. When the season changes, they leave for foreign shores, leaving the little birds behind. Son, I have a feeling that you are one of those seagulls.”
