湿阻的辨证要点何在

阅读理解。

    A blind boy sat on the steps of a building with a box by his feet. He held up a sign which read, "I am blind,

please help." There were only a few coins in the box. The boy felt sad.

    A man walked by. He took a few coins from his pocket and dropped them into the box.Then he took the

sign, turned it around and wrote some words. He put the sign back so that everyone who walked by would

see the new words.

    Soon the box was full. A lot more people were giving money to the blind boy. That afternoon the man who

had changed the sign came to see how things were. The boy recognized his footsteps and asked, "Were you

the one who changed my sign this morning? What did you write?"

    That man said, "I only wrote the truth. I said what you said but in a different way." What he had written

was, "today is a beautiful day and I can not see it." Do you think the first sign and the second sign were

saying the same thing? Of course both signs told people they were so lucky that they were not blind.

    Great men say, "In the journey of life, if you want to travel without fear, you must have the ticket of a

good conscience (良心)."

of a person's smiling!
