Bertie knew there was something in the wind.His mother had been sad in recent days, not sick, just strangely sad.The lion had just lain down beside him, his head warm on Bertie's feet when Father cleared his throat and began, " You'll soon be eight, Bertie.A boy needs a proper education.We've found the right place for you, a school near Salisbury in England."

His heart filled with a terrible fear, all Bertie could think of was his white lion."But the lion," he cried, "What about the lion?"

"I'm afraid there's something else I have to tell you," his father said.Looking across at Bertie's mother, he took a deep breath.Then he told Bertie he had met a circus owner from France, who was over in Africa looking for lions to buy.He would come to their farm in a few days.

"No! You can't send him to a circus!" said Bertie."People will come to see him.He'll be shut up behind bars.I promised him he never would be.And they will laugh at him.He'd rather die.Any animal would! " But as he looked across the table at them, he knew their minds were quite made up.

Bertie felt completely betrayed.He waited until he heard his father's deep breathing next door. With his white lion at his heels, he crept downstairs in his pyjamas, took down his father's rifle from the rack and stepped out into the night.He ran and ran till his legs could run no more.As the sun came up over the grassland, he climbed to the top of a hill and sat down, his arms round the lion's neck.The time had come.

"Be wild now," he whispered."You've got to be wild.Don't ever come home.All my life I'll think of you.I promise I will." He buried his head in the lion's neck.Then, Bertie clambered down the hill and walked away.

When he looked back, the lion was still sitting there watching him; but then he stood up, yawned, stretched, and sprang down after him.Bertie shouted at him, but he kept coming.He threw sticks.He threw stones.Nothing worked.

There was only one thing left to do.With tears filling his eyes and his mouth, he lifted the rifle to his shoulder and fired over the lion's head.

Doctors sometimes prescribe light therapy to treat a form of depression in people who get too little morning sun.But too much light at other times may actually cause such mood disorders. Long-lasting exposure to light at night brings depression, a new study finds, at least in animals.

The new data confirm observations from studies of people who work night shifts, says Richard Stevens of the University of Connecticut Health Center.Mood disorders join a growing list of problems, including cancer, obesity and diabetes梩hat can occur when light throws life out of balance by disturbing the biological clock and its timing of daily rhythms.

In the new study, Tracy Bedrosian and Randy Nelson of Ohio State University exposed mice to normal light and dark cycles for four weeks.For the next four weeks, half of the mice remained on this schedule, and the rest received continuous dim light throughout their night.Compared with mice exposed to normal nighttime darkness, those getting dim light at night lost their strong preference for sweet drinks, " a sign they no longer get pleasure out of activities they once enjoyed," Bedrosian says.

In a second test, mice were clocked on how long they actively tried to escape a pool of water. Those exposed to night lights stopped struggling and just floated in the water, a sign of "behavioral despair" , 10 times as long as the mice that had experienced normal nighttime darkness.All symptoms of depression disappeared within two weeks of the mice returning to a normal light-dark cycle, the researchers report.The scientists also could quash the behavioral symptoms by injecting (注射) the brains of animals with a drug that prohibits the activity of certain molecules linked with human depression.This finding further suggests that light at night may cause something related to depression.

Human studies linking nighttime light and mood disorders are important but can't easily detect molecular underpinnings (分子基础) as animal studies can, says George Brainard of Thomas Jefferson University.The new work, he says, suggests that the change of the biological clock by light at night can be "an extremely powerful force in regulating biology and behavior.

63.After being exposed to continuous nighttime light, the mice ______.

A.changed their preferences            B.escaped from the water more eagerly

C.remained active as before            D.showed less interest in their favorites

A.light at night may have practical value

B.the biological clock is beneficial to humans

C.human mood disorders cannot be healed easily

D.human studies are more important than animal studies

66.What is the main idea of the passage?

A.Nighttime light may foster depression.

B.A drug has been found to cure mood disorders.

C.The study on animals can be applied to humans.

D.Human biological clock can be controlled by lieht.
