We all admire the beautiful blue of a clear sky or the superb contrast between the brilliant white of the clouds and the sky-blue between them. This colour, however, is not natural in the atmosphere; it is an optical effect(光学效应).
When light encounters a cloud of small particles, it is diffused. This may be illustrated by a familiar example. When sunlight enters a darkened room through a gap in the blinds, it will appear as a brilliant ray of light. This is because there are tiny particles of dust suspended in the air. These, although normally invisible, catch and diffuse any strong light shining on them. The same effect can be seen in the sky when broken clouds hide the sun. Thus we can see that diffusion occurs owing to all sorts of impurities in the atmosphere. This explains all the delightfully varied shades of colour seen at different times of the day.
White light is a mixture of all the colors of the rainbow or spectrum(光谱), which, as Isaac New-ton proved, can be separated by a prism. In order, they are red, orange, yellow, green, blue, violet, and they are all to be found in the solar spectrum. Red light has the longest wavelength and violet the shortest but diffused approximately sixteen times more strongly than red.
The size of the particles is important. Impurities such as dust and water droplets are much larger than the molecules of gas. In the lower parts of the atmosphere where most of these impurities are concentrated, the sky is different from what it is at heights where no impurities exist. A simple observation will demonstrate this principle. Examine the smoke from a cigarette before and after it has been inhaled. At first the smoke will be plainly bluish since it is made up of very minute particles; after it has been inhaled and then puffed out through the mouth, it will be yellowish because it now contains water droplets which have condensed round the particles and which are much more efficient diffuse of light.
This is why the colour of the sky is much more intense and dark blue when seen from the top of a mountain than from sea level. In the first place there is an almost complete absence of water vapor and, more important, dust. Secondly, we are above the thickest portions of the atmosphere, and this naturally has the most powerful diffusing effect. The colour of the sky varies from horizon to zenith(天顶), since there is a different thickness of air in these two directions. The horizon always appears lighter, more whitish or even reddish, according to the state of the atmosphere. All this, incidentally, also intensifies the illusion of being under a great dome—the celestial roof.
When sunlight enters a dark room through the blinds ______.
A．particles of dust are suspended
B．tiny dust particles become visible
C．it is very bright
D．it becomes visible

It was New Year's night. An aged man was standing at a window. He raised his mournful eyes towards the deep blue sky, where the stars were floating like white lilies on the surface of a clear calm lake. Then he cast them on the earth, where few more hopeless people than himself now moved towards their certain goal—the tomb. He had already passed sixty of the stages leading to it, and he had brought from his journey nothing but errors and regret. Now his health was poor, his mind vacant, his heart sorrowful, and his old age short of comforts.
He looked towards the sky and cried painfully, “O youth, return! O my father, place me once more at the entrance to life, and I'll choose the better way !” But both his father and the days of his youth had passed away.
The days of his youth appeared like dreams before him, and he recalled the serious moment when his father placed him at the entrance of the two roads—one leading to a peaceful, sunny place, covered with flowers，fruits and resounding with soft, sweet songs ; the other leading to a deep, dark cave, which was endless, where poison flowed instead of water and where devils and poisonous snakes hissed and crawled. ①
He was the lights flowing away in the darkness. These were the days of his wasted life; he saw a star fall from the sky and disappeared, and this was the symbol of himself. His remorse, which was like a sharp arrow，struck deeply into his heart. Then he remembered his friends in his childhood, who entered on life together with him. But they had made their way to success and were now honoured and happy on this New Year's night.
The clock in the high church tower struck and the sound made him remember his parents' early love for him. They had taught him and prayed to God for his good. But he chose the wrong way. With shame and grief he dared no longer look towards that heaven where his father lived. His darkened eyes were full of tears, and with a despairing effort, he burst out a cry: “Come back， my early days! Come back!”
And his youth did return, for all this was only a dream which he had on New Year's night. He was still young though his faults were real; he had not yet entered the deep, dark cave, and he was still free to walk on the road which leads to the peaceful and sunny land.
Those who still linger on the entrance of life, hesitating to choose the bright road, remember that when years are passed and your feet stumble on the dark mountains, you will cry bitterly, but in vain: “O youth, return! Oh give me back my early days!”②

through the clothing factory districts, then down along the avenues to the East Side.
I met my father near Cooper Union. I recognized him, a hunched, frozen figure in an old overcoat standing by a banana cart. He looked so lonely, the tears came to my eyes. Then he saw me, and his face lit with his sad, beautiful smile-Charlie Chaplin's smile.
"Arch, it's Mikey," he said. "So you have sold your papers! Come and eat a banana."
He offered me one. I refused it. I felt it crucial that my father sell his bananas, not give them away. He thought I was shy, and coaxed and joked with me, and made me eat the banana. It smelled of wet straw and snow.
"You haven't sold many bananas today, pop," I said anxiously.
He shrugged his shoulders.
"What can I do？ No one seems to want them."
It was true. The work crowds pushed home morosely over the pavements. The rusty sky darkened over New York buildings, the tall street lamps were tit, innumerable trucks, street cars and elevated trains clattered by. Nobody and nothing in the great city stopped for my father's bananas.
"I ought to yell, "said my father dolefully. "I ought to make a big noise like other peddlers, but it makes my throat sore. Anyway, I'm ashamed of yelling, it makes me feel like a fool."
I had eaten one of his bananas. My sick conscience told me that I ought to pay for it somehow. I must remain here and help my father.
"I'll yell for you, pop," I volunteered.
"Arch, no," he said, "go home; you have worked enough today, lust tell momn I'll be late."
But I yelled and yelled. My father, standing by, spoke occasional words of praise, and said I was a wonderful yeller. Nobody else paid attention. The workers drifted past us wearily, endlessly; a defeated army wrapped in dreams of home. Elevated trains crashed; the Cooper Union clock burned above us; the sky grew black, the wind poured, the slush burned through our shoes. There were thousands of strange, silent figures pouring over the sidewalks in snow. None of them stopped to buy bananas. I yelled and yelled, nobody listened.
My father vied to stop me at last. "Nu," he said smiling to console me, "that was wonderful yelling, Mikey. But it's plain we are unlucky today! Let's go home."
I was frantic, and almost in tears. I insisted on keeping up my desperate years. But at last my father persuaded me to leave with him.

I remember meeting him one evening with his pushcart. I had managed to sell all my papers and was coming home in the snow. It was that strange hour in downtown New York when the workers were pouring homeward in the twilight. I marched among thousands of tired men and women whom the factory whistles had unyoked. They flowed in rivers through the clothing factory districts, then down along the avenues to the East Side.
I met my father near Cooper Union. I recognized him, a hunched, frozen figure in an old overcoat standing by a banana cart. He looked so lonely, the tears came to my eyes. Then he saw me, and his face lit with his sad, beautiful smile -Charlie Chaplin's smile.
