      ①信仰，就是相信人生中有一种东西，它比自己的生命重要得多，甚至是人生中最重要的东西，值得为之活着，必要时也值得为之献身。这种东西必定是高于我们的日常生活的，像日月星辰一样在我们头顶照耀，我们相信它并且仰望它，所以称作信仰。但是，它又不像日月星辰那样可以用眼睛看见，而只是我们心中的一种观念，所以又称作信念。
      ②真正的信仰是相信人生应该有崇高的追求，真正看重信仰的人决不盲目相信某一种流行的宗教或别的什么思想，而是通过独立思考来寻求和确立自己的信仰。两千四百年前，苏格拉底的信仰就是：人生的价值在于爱智慧，用理性省察生活尤其是道德生活。他为自己的信仰献出了宝贵的生命。
      ③信仰是内心的光，它照亮了一个人的人生之路。没有信仰的人犹如在黑暗中行路，不辨方向，没有目标，随波逐流，活一辈子也只是浑浑噩噩。当然，一个人要真正确立起自己的信仰，这不是一件容易的事。在我看来，在信仰的问题上，真正重要的是要有真诚的态度。所谓真诚，第一就是要认真，既不是无所谓，可有可无，也不是随大流，盲目相信；第二就是要诚实，决不自欺欺人。有了这种真诚的态度，即使你没有找到一种明确的思想形态作为你的信仰，你也可以算作一个有信仰的人了，因为你至少是在信仰着一种有真诚追求的人生境界。

    Natalie Doan, 14, has always felt lucky to live in Rockaway, New York. Living just a few blocks from the beach, Natalie can see the ocean and hear the wave from her house. "It's the ocean that makes Rockaway so special," she says.
    On October 29, 2012, that ocean turned fierce. That night, Hurricane Sandy attacked the East Coast, and Rockaway was hit especially hard. Fortunately, Natalie's family escaped to Brooklyn shortly before the city's bridge closed.
    When they returned to Rockaway the next day, they found their neighborhood in ruins. Many of Natalie's friends had lost their homes and were living far away. All around her, people were suffering, especially the elderly. Natalie's school was so damaged that she had to temporarily attend a school in Brooklyn.
    In the following few days, the men and women helping Rockaway recover inspired Natalie. Volunteers came with carloads of donated clothing and toys. Neighbors devoted their spare time to helping others rebuild. Teenagers climbed dozens of flights of stairs to deliver water and food to elderly people trapped in powerless high-rise buildings.
    "My mom tells me that I can't control what happens to me," Natalie says. "But I can always choose how I deal with it."
    Natalie's choice was to help. She created a website page matching survivors in need with donors who wanted to help. Natalie posted introduction about a boy named Patrick, who lost his baseball card collecting when his house burned down. Within days, Patrick's collection was replaced. In the coming months, her website page helped lots of kids: Christopher, who received a new basketball; Charlie, who got a new keyboard.Natalie also worked with other organizations to bring much-need supplies to Rockaway. Her efforts made her a famous person. Last April, she was invited to the White House and honored as a Hurricane Sandy Champion of Change.
    Today, the scars of destruction are still seen in Rockaway, but hope is in the air. The streets are clear, and many homes have been rebuilt. "I can't imagine living anywhere but Rockaway," Natalie declares. "My neighborhood will be back, even stronger than before."
