任务型阅读(每小题1分,满分10分) 请认真阅读下面短文,并根据所读内容在文章后表格中的空格里填入最恰当的单词。 Children who grow up with self-control and an understanding of others’ needs will be happy and successful adults, according to Dr. Cleen Kelly Mast, an expert on children’s health. The key to raising a successful child comes from realizing what is true happiness. For a person to be truly happy, he or she should learn to form the habits of self-discipline and generosity (慷慨). Parents must help their children to reach this point by emphasizing the development of virtue and the advantage of forming good habits. “We have wonderful support systems through our schools,” Dr. Mast said, “but they are just support systems. The school cannot make up for what is lacking at home.” According to Dr. Mast, family life is well suited to educate children in virtuous living and the development of what she calls a “fine-tuned” conscience, which brings happy feeling. So how can busy parents help children fine-tune their consciences? Dr. Mast suggested parents stop blaming and criticizing and teach children the skills of self-discipline through concrete actions. However, a parent’s good example is not enough. Children must become involved in their own development. Parents can help to achieve that by making children realize that they are responsible for their actions in difficult situations, and they can choose to stop protecting them from painful experiences as well. Good discipline is not just making children follow their parents’ demands. “We parents must encourage them with more than ‘Because I said so.’” said Dr. Mast. Besides, orderliness and organization are quite important for children to achieve self-discipline. In a broad sense, humans are designed to love, and love involves sacrifice, which is not a quite popular idea in the modern world. Parents need to work on developing their children’s habits of generosity and kindness to others. “Help your child, and yourself, to think kind thoughts of others, while pushing out negative thoughts.” said Dr. Mast. She also suggested parents find out their children’s nature by analyzing the way they react to situations or to other people. And it is also considered effective to have them develop the habit of reviewing the day nightly, with a focus on correcting their own particular faults. But life is not all work and no play. All have the right to enjoy life. As parents, it is your duty to help your children form good habits and let them have fun while working hard, which will result in success when they grow up.
