Roy wasn't the only one to receive his call-up（入伍）papers．Stephen Napier's call-up came at the beginning of February and he was pleased to find that he would be going into the Royal Air Force (RAF)．
His father was not so pleased and made his feelings known as he and Stephen were on their daily walk. It was the first step in his plans for Stephen to take over the estate（地产）when the time came, and although Stephen was well aware of this, he could think of no reason not to accompany him.
"Thought you'd forgotten that nonsense. Still, I dare say I could pull a few strings to get you to the Army..."
"No, Father! I have told you I want to learn to fly. What chance would I have to do that in the Army? I'd be better off in the Navy——at least they've got the Fleet Air Arm. But I have been put in the RAF and that's where I want to be, so let's leave it at that." His face went red. Sent to his father's school and then to Cambridge, much to his satisfaction, he had never had to defend his own desires and his father was a hard man to oppose.
The father glared at Stephen, "No, I won't leave it at that. I want to know what other ridiculous ideas are in your head. For a start, what's all this about America?"
"America?"
"Yes. All those books I saw in your room the other day. Brochures about emigration（移民）．"
The big, silvered head lo
wered, like that of a bull about to charge．"Don't trouble to deny it."
"I won't, Father. Some men at Cambridge have been talking about it. They want people like us here, mathematicians and scientists, for all kinds of research——the sort of research I could do．It would be a worthwhile life for me."
The father responded exactly as his son had known he would．"You've got a worthwhile life here！You've got an estate to run！"
"No, Father. You've got an estate to run. I never asked for it. Why not ask Baden to do this stuff? He perhaps can make a good job of it, but I..."
"If he were here, I might think about this silly idea of yours——only think about it, mind you but..."

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.

| 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 |
| 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. |
| 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 |
| A．The Period3 Gene | B．The Function of Genes |
| C．Wake up, Sleepy Gene | D．Stay up Late or Get up Early? |
