Donna Ashlock, a 14-year-old girl from California, was very sick. She had a bad heart. “Donna needs a new heart,” her doctor said, “she must have a new heart, or she will die soon.”

 Felipe Carza, 15, was worried about Donna. Felipe was Donna’s friend. He liked Donna very much. He liked her freckles, and he liked her smile. Felipe didn't want Donna to die.

 Felipe talked to his mother about Donna. “I am going to die,” Felipe told his mother, “and I am going to give my heat to Donna.”

 Felipe's mother didn't pay much attention to Felipe. “Felipe is just kidding,”she thought, “Felipe is not going to die. He's strong and healthy.”

 But Felipe was not healthy. He had terrible headaches sometimes. “my head hurts,”he often told his friends. Felipe never told his parents about his headaches.

 One morning Felipe woke up with a sharp pain in his head. He was dizzy (眩晕的), and he couldn’t breathe. His parents rushed Felipe to the hospital. Doctors at the hospital had terrible news for them. “Felipe's brain is dead,”the doctors said, “we can't save him.”

 The parents were very sad. But they remembered Felipe's words. “Felipe wanted to give his heart to Donna,”they told the doctors.

 The doctors did several tests. Then they told the parents, “we can give Felipe's heart to Donna.”

 The doctors took out Felipe's heart and rushed the heart to Donna. Other doctors took out Donna’s heart and put Felipe's heart in her chest. In a short time the heart began to beat.

 The operation was a success. Felipe's heart was beating in Donna’s chest, but Donna didn't know it. Her parents and doctors didn't tell her. They waited until she was stronger; then they told her about Felipe. “I feel very sad,”Donna said, “but I am thankful to Felipe.”

 Three months later the operation Donna went back to school. She has to have regular checkups, and she has to take medicine every day. But she is living a normal life.

 Felipe's brother John says, “Every time we see Donna, we think of Felipe. She has Felipe's heart in her. That gives us great peace.”

阅读材料，完成下列要求

材料一：进入新常态的中国经济，面临一系列新的突出矛盾和问题。2015年12月召开的中央经济工作会议强调，要在适度扩大总需求的同时，着力 加强供给侧结构性改革，要按照企业主体、政府推动、市场引导、依法处置的办法，研究制定全面配套的政策体系。供给侧结构性改革，就是从供给，生产入手，解放和发展社会生产国力，也就是，用改革的办法推进结构调整，减少无效和低端供给，扩大有效和中高端供给，增强供给结构对需求变化的适应性和灵活性，提高全要素生产率

材料二：目前在我国的农业生产中，化肥、农药等滥用现象严重，19%的土壤受到重金属污染，农产品品质低，每年农业科研投入只占财政支出的 ，生产成本高，利润低；人们对农产品的需求已经由“吃饱”向“吃好”、“吃环保”、“吃生态”转变，农产品生产供给与市场群体对优质农产品需求之间的矛盾日益突出，“卖不出去”与“买不到”共存，因而国家提出要进行“农业供给侧结构性改革”。

    2016年“两会”如何进行供给侧结构性改革引起代表、委员们的热议，有的认为国家要制定农业生产结构和区域布局规划纲要，依此扭转农业重复生产的现状；有的认为以土地的规模化经营解决“单家独户”生产模式带来的机械化低，监管难度大，成本高等问题；也有的提出要加快标准化步伐，出台支持有机农业发展的有关措施，另外许多网民也纷纷在网络上就这一问题发表了自己的看法。
