Of course we should laugh during the happy times. _1_Erma Bombeck is known for her humorous books, but she wrote one that covered a more serious topic：cancer in children. Erma talks with lots of children with cancer and learns “important life lessons from them._2_She tells the experience of 15yearold Jessica from Burlington. Jessicas leg wasamputated(锯掉) at the knee because of cancer. Jessica tells about playing soccer. She kicked the ball hard and it flew off in one direction while her artificial leg flew another way. Then “The tall, pretty person that I am，” she said, “sat on the floor in laughter.”Jessica may not have laughed about her cancer, but she laughed about dealing with its results. _3_Then there is the story of 17yearold Betsy. She made her way to theradiationroom (放射室) for her regular radiation therapy. As usual, she dropped her hospital gown and, wearing only her birthday suit, climbed onto the table and waited.

Reuse and Recycle.“The order is important.2 .” says Eugene Tay, Director of Green Future Solutions in Singapore. “Recycling still affects the environment and should be done last after reduce and reuse.”But, when our efforts to reduce and reuse still result in an overflowing rubbish bin, the advantages of recycling cannot be ignored. “3 .” says Amy Ho Managing Director of World Wide Fund For Nature in Singapore. “The damage to our environment could then be slowed down as a result.”In fact, by recycling just one plastic bottle, you are saving not just the material to
