The power of encouragement is great. You may draw some inspiration from the following story.
Dante Gabriel Rossetti, a famous 19th­century poet and artist, was once  26  by an elderly man. The old man had some sketches (素描) and drawings that he  27  　Rossetti to look at them and tell him if they were any good, or  28  they at least showed potential(潜在的)talent.
Rossetti looked them  29  carefully. After the first few, he knew that they were worthless, showing not the least sign of artistic talent. But Rossetti was a  30  man, and he told the elderly  31  as gently as possible that the pictures were of little value and showed little talent. He was sorry,  32  he could not　33  to the man.
The visitor was  34  , but seemed to expect Rossetti’s  35   .He then apologized for  36  Rossetti’s time, but would he just  37  a few more drawings—these done by a(n)  38  art student？Rossetti looked over the  39  batch (一批) of sketches and immediately became  40  over the talent they revealed(显示；透露) .“These,” he said,“Oh, these are good. This young student has great talent. He should be  41  every help and encouragement in his career as an artist. He has a hopeful future if he will work and stick to it.”
Rossetti could see that the old man was  42  moved.“Who is this fine young   artist？” he asked.“Your son？” “No,” said the old man sadly.“It was I  43  painted the pictures forty years ago.  44  I had heard your praise then！For you see, I got discouraged and 45  drawing—too soon.”

Some years ago, writing in my diary used to be a usual activity. I would return from school and spend the expected half hour recording the day’s events, feelings, and impressions in my little blue diary. I did not really need to express my emotions by way of words, but I gained a certain satisfaction from seeing my experiences forever recorded on paper. After all, isn’t accumulating memories a way of preserving the past?

　When I was thirteen years old, I went on a long journey on foot in a great valley, well-equipped with pens, a diary, and a camera. During the trip, I was busy recording every incident, name and place I came across. I felt proud to be spending my time productively, dutifully preserving for future generations a detailed description of my travels. On my last night there, I wandered out of my tent, diary in hand. The sky was clear and lit by the glare of the moon, and the walls of the valley looked threatening behind their screen of shadows. I automatically took out my pen….

At that point, I understood that nothing I wrote could ever match or replace the few seconds I allowed myself to experience the dramatic beauty of the valley. All I remembered of the previous few days were the dull characterizations I had set down in my diary.

Now, I only write in my diary when I need to write down a special thought or feeling. I still love to record ideas and quotations that strike me in books, or observations that are particularly meaningful. I take pictures, but not very often—only of objects I find really beautiful. I’m no longer blindly satisfied with having something to remember when I grow old. I realize that life will simply pass me by if I stay behind the camera, busy preserving the present so as to live it in the future.

I don’t want to wake up one day and have nothing but a pile of pictures and notes. Maybe I won’t have as many exact representations of people and places; maybe I’ll forget certain facts, but at least the experiences will always remain inside me. I don’t live to make memories—I just live, and the memories form themselves.

　Many people believe the glare（炫目的光）from snow causes snowblindness. Yet, with dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness ,when exposed to several hours of“snow light”.

　　The United States army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country. Rather, a man’s eyes frequently find nothing to focus on（聚集）in a broad space of snow-covered without-grass land. So his gaze continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding something, hour after hour, the eyes never stop searching and the eyeballs become tired and the eye muscles ache. Nature makes up for this discomfort by producing more and more fluid（流体）which covers the eyeball. The fluid covers the eyeball in increasing quantity until it makes eyes difficult to see dearly, and the result is total, even though for a short time, snowblindness.

　　Experiments led the Army to a simple method of overcoming this problem. Scouts（侦察兵）ahead of the troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark-colored objects ahead on which they can focus too. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a continuous white land is overcome.

To prevent snowblindness caused by the strong light from snow, wearing glasses or not _____.

　　A. depends on whether the snow is white enough    　B. makes no difference

　　C. makes much difference        　　            D. depends on whether the snow is thick

When the eyes are tired, tears flow out ______.

　　A. to clear the vision                             B. to make the eyes stop searching

　　C. to make the vision unclear                      D. to produce more and more liquid

Snowblindness can be avoided ________.

　　A. by moving one’s gaze back and forth

　　B. by walking ahead and keeping looking around

　　C. by making up for the discomfort of one’s eyes

　　D. by providing the eyes with something to focus on
