| 请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。 We should not hesitate too much during the first half of our lives, while we should not regret at what we've done during the other half. We should seize every opportunity (机会) to find a way out in our lives, for it goes off quickly. We should say something urgent (紧迫的) slowly, something serious clearly, something small humorously and something unsure carefully. We should never say something that did not happen, something that we cannot do, something that does harm to others. Do not easily say something about others. We should follow our own heart and interest, and fulfill what we should do. Everyone is longing for a happy life, but owning wealth does not necessarily mean owning happiness. To truly reach happiness, we need to know how to get on with others. So we need to understand the core (核心) of happiness and achieve what we desire. We need to know and understand happiness before we finally get it. A smart man must know to do something good even though it may be small, and not to do something evil even though it may be tiny in everyday life. As long as we keep a kind heart and do everything legally, we can live a peaceful life. But if we keep an evil heart and do whatever we want, we are indeed digging a tomb for ourselves. A smart man knows to learn a lesson from his falls for he knows that every fall is a valuable experience leading to happiness in the future. He will not waste his time in criticizing (批评)others. Instead, he tends to spend more time seeking his own happiness. He knows to keep a heart of conscience (道德) and not to spread others' mistakes. He also knows to think before he leaps so that he will not feel regretful afterwards. Moreover, he knows to tolerate others, so he can naturally lead a happy life. Without happiness, one will feel terribly sorry, for he always insists that he has done the right thing all the time and that others often do wrong to him. He attributes (把……归于) every mistake to others or the environment instead of reflecting on himself, which keeps him farther and farther away from happiness. A well-known person once said, "Nobody intends to make mistakes. One makes mistakes because of his ignorance (无知)." Therefore, if someone makes mistake, we need to care about him, forgive him and enlighten (启发) him by setting a good example to him instead of losing temper (怒气) to him. Otherwise, we are also ignorant like him, for we also make a stupid mistake that leads us farther from happiness. In order to lead a happy life, we need to know more about others, about the society, about our culture and history. We should love our country, keep the law and realize our own responsibility (责任), and then we are sure to have a happy life.
