【简答题】
Like any good mother, when Karen found out that another baby was on the way, she did what she could to help her 3-year-old son, Michael, prepare for a new sister. And day after day, night after night, Michael sang to his sister in Mommy’s tummy(肚子). Everything was normal for Karen. But she had difficulty giving birth to the baby. Finally, Michael’s little sister was born. But she was in serious condition and was sent to hospital at once. The days went by. The little girl got worse. The doctor told the parents, “There is very little hope. Be prepared for the worst.” Karen and her husband had fixed up a special room in their home for the new baby—now they planned a funeral. Michael, kept begging his parents to let him see his sister, “I want to sing to her,” he said. Karen knew if he didn’t see his sister now, he would never see her alive. She led Michael to his sister’s bedside. In the pure-hearted voice of a 3-year-old, Michael sang: “You are my sunshine, my only sunshine; you make me happy when skies are gray…” Immediately the baby girl responded. Her breath became calm. “Keep on singing, Michael!” ‘You never know, dear, how much I love you. Please don’t take my sunshine away…” Tears ran down Karen’s face. Funeral plans were cancelled(取消). The next day, the little girl was well enough to go home! The doctors just called it a miracle(奇迹). Karen called it a miracle of God’s love! 小题1:Before his sister’s birth, Michael _____ .
