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 during the happy times.   小题1: . 小题2: But she wrote one about a more serious subject--cancer in children. The book is titled I WANT TO GROW HAIR, I WANT TO GROW UP. Erma talks with many children who have cancer and learns important lessons from them. She learns, for example, that cancer survivors(幸存者)know how they should smile at life, though they are receivingchemotherapy(化疗).

 小题3: .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 with her foot. The ball flew off in one direction while her man-made leg flew another way. Then the brave girl lay on the floor, laughing happily.

As the saying goes, “ 小题4: ” Do you find plenty of time to laugh?

You can, if you find reasons to laugh during the difficult times. 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 laughs with you.  小题5: .
