Smiles and tears are part of life. But do you find enough time for laughing? I'm not asking if you experience lots of good times . Of course, we should laugh        the happy times. But do you also laugh during the difficult times?
Erma Bombeck is famous        her funny books. But she wrote        about a more serious subject-cancer (癌症) in children. The book is titled, I WANT TO GROW        , I WANT TO GROW UP. Erma talks with many children who        cancer and learns important lessons from them. She learns, for example, that cancer survivors (幸存者) know how to smile at life, though they are receiving chemotherapy (化疗).
She tells about the experience of        Jessica. Jessica's leg was cut off at the knee because of cancer. She was learning to wear a prosthesis (假肢). Jessica told about playing soccer. She hit the ball hard        her foot. The ball flew off in one direction (方向)        her man-made leg flew another way. Then the brave girl lay on the floor, laughing happily.
As the saying goes, "There's a time       and a time to laugh." Do you find        time to laugh?
Survivors know how to laugh If you can laugh even when you're in trouble, you will make it. Remember, laugh and the whole world laugh with you. Cry and you cry alone!
