    It was warm for a Sunday afternoon in early January. Kevin loved being outdoors among the wild rosebushes in front of his house with a view of distant mountains.

    It had been a good day for his wife, Sharon, too. They spent the morning in front of the house, talking and drinking tea. Sharon felt strong and tried her best to cook, starting a pot of homemade soup — a task that would have been nothing a few years ago, but is a little hard for her now. Her illness had left her weak, often puzzled.

    Sharon was the take-charge person in the family. She was seldom sick until 1997, when she began suffering from terrible headaches. One day at work, colleagues said she didn't look right and urged(敦促) her to go to the hospital. She rose from her chair and fell over. She could hear voices, but couldn't speak. It looked as if she'd had a stroke(中风).

    Other stroke-like symptoms (症状) followed. She had difficulty walking. She ran a fever all the time. The headaches never stopped. She and Kevin spent all their savings seeing doctors and on medical tests.

    In 2000, physicians said Sharon had brain damage that left her with symptoms resembling dementia (痴呆症). Once, she visited a familiar store and couldn't remember where the exit was. Another time, she was making spaghetti, but didn't know what to do after the water boiled.

    After seeing specialists, Kevin and Sharon came to believe that exposure(接触) to mould(霉菌) had caused Sharon's condition. Her world was certainly getting worse. At times she needed a wheelchair. The woman who never liked asking for help had to stay at home and rely on her husband.

阅读与应用：

阅读1：a、b为实数，且a＞0，b＞0，因为${\left(\sqrt{a}-\sqrt{b}\right)}^2\ge 0$，所以$a-2\sqrt{ab}+b\ge 0$从而$a+b\ge 2\sqrt{ab}$（当a=b时取等号）．

阅读2：若函数y=x+$\frac{m}{x}$；（m＞0，x＞0，m为常数），由阅读1结论可知：x+$\frac{m}{x}$≥$2\sqrt{m}$，所以当x=$\frac{m}{x}$，即x=$\sqrt{m}$时，函数y=x+$\frac{}{}$$\frac{m}{x}$的最小值为$2\sqrt{m}$$$．
