阅读下面文言文，完成下列小题。

    仇钺，字廷威，镇原人。初以庸卒给事宁夏总兵府，大见信爱。会都指挥佥事仇理卒，无嗣，遂令钺袭其世职。正德二年，用总制杨一清荐，擢宁夏游击将军。五年，安化王寘鐇及都指挥何锦、周昂、指挥丁广反。钺时驻城外玉泉营闻变欲遁去顾念妻子在城中恐为所屠灭遂引兵入城解甲觐寘鐇归卧家称病以所将兵分隶贼营。锦等信之，时时就问计。钺亦谬输心腹。而阴结壮士，遣人潜出城，令还报官军旦夕至。钺因绐锦、广，宜急出兵守渡口，遏东岸兵，勿使渡河。锦、广果倾营出，而昂独守城。寘鐇以祃牙召钺，钺称病亟。昂来视，钺方坚卧呻吟。伏卒猝起，捶杀昂。钺乃提其首，跃马大呼，壮士皆集，径驰诣寘鐇第，缚之，众遂大溃。举事凡十八日而败。先是，中朝闻变，议以神英为总兵官，而命钺为副。俄传钺降贼，欲追敕还。大学士杨廷和曰：“钺必不从贼，令知朝廷擢用，志当益坚。不然，弃良将资敌人耳。”乃不追。事果定。而刘瑾暱陕西总兵官曹雄，尽以钺功归之，钺竟无殊擢。瑾诛，始进署都督佥事，充宁夏总兵官。寻论功，封咸宁伯，岁禄千石，予世券。八年，大同有警，命充总兵官，统京军御之。钺上五事，中请遣还京操边军，停京军出征，以省公私之扰。尤切时弊，时不能用。钺既至，值寇犯万全沙河。击之，斩首三级，而军士亡者二十余人，寇亦引去。奏捷蒙赉，朝论耻之。十年冬，称疾解营务。卒年五十七，谥武襄。

   Mrs. Thompson came to the 5th grade class and noticed that Teddy was always alone. Also, he did badly in his studies. When she reviewed Teddy’s past records，she find he was a good child at first，but he began to change when his mother got ill. Finally he lost interest in school after his mother’s death.
   Mrs.Thompson realized the problem and felt sorry for him. She felt even worse when her students brought her beautifully-covered Christmas presents. His presents were covered with some old paper. Some children laughed when she found a bracelet(手镯)with some of the stones missing, and a bottle with a little perfume(香水). But she said how pretty the bracelet was, putting it on, and dabbing some perfume on her hand. Teddy stayed after school for a long time just to say，“Mrs.Thompson，today you smelled just like my mom used to.” After the child left，she cried for quite a long time.
   On that very day，she taught not only knowledge but also children. As she worked with Teddy，his mind seemed to come alive. By the end of the year，Teddy had become one of the smartest children in the class.
   A year later，Teddy left school. She found a note under her door，from Teddy，saying that she was the best teacher he ever had in his life. After that, these words were repeated in each of his letters to her.
   Then after he finished college, Teddy wrote telling her that he had met a pretty girl and was going to get married. He explained that his father was dead，and that he wondered if Mrs.Thompson might sit at the wedding in the place for the mother of the groom(新郎).
Of course，Mrs.Thompson did. She wore the bracelet and the perfume that Teddy remembered his mother wearing on their last Christmas together.
   They hugged(拥抱)each other，and Teddy whispered in Mrs.Thompson's ear，“Thank you，Mrs.Thompson，for making me feel important，and showing me that I could make a difference. ”
   Mrs.Thompson，with tears in her eyes，whispered back，“Teddy，it's not like that. You were the one who taught me that I could make a difference. I didn’t know how to teach until I met you.”
