让生命化蛹为蝶

    一个小孩，相貌丑陋，说话口吃，而且因为疾病导致左脸局部麻痹（pì  bì），嘴角畸（jī  qí）形，说话时嘴巴总是歪向一边，还有一只耳朵失聪。

    为了矫正自己的口吃，这孩子模仿古代一位有名的演说家，嘴里含着小石子讲话：看着嘴巴和舌头被石子磨烂的儿子，母亲心疼地抱着他流着眼泪说：“不要练了。妈妈一辈子陪着你。”懂事的他替妈妈擦着眼泪说：“妈妈，书上说，每一只漂亮的蝴蝶。都是自己冲破束缚它的茧之后才变成的。我要做一只美丽的蝴蝶。”

    后来，他能流利地讲话了。因为他的勤奋和善良，他中学毕业时，______取得了优异成绩，______有了很多好朋友。

    1993年10月，他参加全国总理大选时，他的成长经历被人们知道后，赢得了选民极大的同情和尊敬。加上他提出的竞选口号“我要带领国家和人民成为一只美丽的蝴蝶”极大地鼓舞了人民，使他以高票当选为总理，并在1997年再次获胜，连任总理，人们亲切地称他是“蝴蝶总理”。他就是加拿大第一位连任两届的总理让·克雷蒂安。

    是的，有些东西我们无法改变，比如贫苦的出身，丑陋的相貌，痛苦的遭遇。这些都是我们生命中的“茧”。但有些东西我们人人都可以选择，比如自尊、自信、毅力、勇气，它们是帮助我们穿破命运之茧。由蛹化蝶的生命之剑。

    Last summer, Mac Hollan, a primary school teacher, was cycling to Alaska with two friends. On the way, his friends had to stop for a bicycle repair, but they encouraged Mac to ride on, and they would catch up with him soon.

    Mac began to cycle alone. A few minutes later, Mac heard quick and loud breathing behind him. "Man, that's a big dog!" he thought. But when he looked to the side, he saw immediately that it wasn't a dog at all, but a wolf, quickly catching up with him.

    Mac's heart jumped. He searched and took out his can of bear spray（防熊喷雾）. With one hand on the bars, he fired the spray at the wolf. A bright red cloud enveloped the animal. To Mac's relief（宽慰）, it fell back, shaking its head. A minute later, however, it was again by his side. It even attacked the back of Mac's bike, tearing open his tent bag. He fired at the wolf a second time, and again, it fell back, only to quickly restart the chase（追赶）.

    Mac was riding hard now. He waved and shouted at passing cars without slowing down.

    At that moment, Paul and Becky were driving their car on their way to Alaska. They found a dog-like animal running alongside a man on a bike. As they got closer, they realized that the "dog" was a wolf. Mac heard a large car behind him. He kept waving and shouting as the wolf was catching up closer. And the car did stop in front of him at the right time.
