All day long he flew, and at night-time he arrived at the city. “Where shall I put up?” he said; “I hope the town has made preparations.”

Then he saw the statue(雕像) on the tall column.

“I will put up there, ” he cried; “it is a fine position, with plenty of fresh air.” So he flew down and settled just between the feet of the Happy Prince.

“I have a golden bedroom,” he said softly to himself as he looked around, and he prepared to go to sleep; but just as he was putting his head under his wing, a large drop of water fell on him.

“What a curious thing!” he cried; “there is not a single cloud in the sky, the stars are quite clear and bright, and yet it is raining. The climate in the north of Europe is really terrible. ”

Then another drop fell.

“What is the use of a statue if it cannot keep the rain off?” he said; “I must look for a good chimney-pot,” and he determined to fly away.

But before he had opened his wings, a third drop fell, and he looked up, and saw –AH! What did he see?

The eyes of the Happy Prince were filled with tears, and tears were running down his golden cheeks. His face was so beautiful in the moonlight that the little Swallow was filled with pity.

“Who are you? ” he said.

“ I am the Happy Prince. ”

“ Why are you weeping(哭泣) then?” asked the Swallow; “you have quite wetted me.”

“When I was alive and had a human heart, ” answered the statue, “I did not know what tears were, for I lived in Palace of Sans-Souci(無憂宮)，where sorrow is not allowed to enter. In the daytime I played with my companions in the garden, and in the evening I led the dance in the Great Hall. Round the garden ran a very high wall, but I never cared to ask what lay beyond it, everything about me was so beautiful. People called me the Happy Prince, and happy indeed I was, if pleasure be happiness. So I lived, and so I died. And now that I am dead they have set me up here so high that I can see all the ugliness and all the misery of my city, and though my heart is made of lead(鉛), yet I can’t choose but weep.”

“ What! Is he not solid gold? ” said the Swallow himself. He was too polite to make any personal remarks out loud.

All we have a clock located inside our brains. Similar to your bedside alarm clock, your internal clock runs on a 24-hour cycle. This cycle, called a circadian (晝夜節(jié)奏的) rhythm, helps control when you wake, when you eat and when you sleep.

Somewhere around puberty, something happens in the timing of the biological clock. The clock pushes forward, so adolescents and teenagers are unable to fall asleep as early as they used to. When your mother tells you it's time for bed, your body may be pushing you to stay up3 for several hours more. And the light coming from your computer screen or TV could be pushing you to stay up even later.

This shift is natural for teenagers. But staying up very late and sleeping late can get your body's clock out of sync with the cycle of light and dark. It can also make it hard to get out of bed in the morning and may bring other problems, too. Teenagers are put in a kind of a gray cloud (提不起精神的狀態(tài)) when they don't get enough sleep, says Mary Carskadon, a sleep researcher at Brown University in Providence, Rhode Island. It affects their mood and their ability to think and learn.

But just like your alarm clock, your internal clock can be reset. In fact, it automatically resets itself every day. How? By using the light it gets through your eyes.

Scientists have known for a long time that the light of day and the dark of night play important roles in setting our internal clocks. For years, researchers thought that the signals that synchronize the body's clock were handled through the same pathways that we use to see. But recent discoveries show that the human eye has two separate light-sensing systems. One system allows us to see. The second system tells our body whether it's day or night.
