阅读《谦和是一种力量》,回答小题。
                                                                                               谦和是一种力量
       ①在纷繁复杂的社会中,你总是要面对各种各样的问题。当冲突横亘在你的面前时,你会选择哪一种态度来面对呢?是不顾一切地发泄心中的愤恨,还是谦和、冷静地思考?我们的答案是后者。
         ②谦者,谦虚,谦让也。它根源于人的辞让之心,体现在人际关系中就是互相尊重。孔子言:“礼之用,和为贵。”(一)“和”历来被认为是君子的重要品质。“谦”“和”都体现了中华民族的传统美德。
         ③谦和具有化解矛盾的力量。愤愤不平的廉颇,纵使百般刁难,甚至扬言“我见相如必辱之”,蔺相如却能以大局为重,隐忍退让,“先国家之急而后私仇也”,最终使廉颇负荆请罪,留下“将相和”的千古佳话。试想如果蔺相如不能隐忍退让,与廉颇势不两立,势必会削弱赵国的力量,极有可能导致赵国覆亡。所以说,愤怒看似凶猛,但却在谦和忍让中化为和谐。
        ④谦和具有打动人心的力量。昔日,刘备放下皇叔州牧的身份,顶风冒雪,不顾路途难行,心怀赤诚,三次来到乡野荒村,访贤求才。第三次时,离草庐半里,他便下马步行,听闻孔明午睡未起,便静候在草堂阶下,终于用谦虚的态度、真诚的心意打动了卧龙先生。(二)这才使三顾茅庐成为千秋美谈,三分天下成为历史功业。
         ⑤谦和还具有给人带来快乐和幸福的力量。谦和的态度使你更容易让人接近,谦和的微笑总是能给你带来好运气。也许一点点的善意、理解、宽容和付出,就会给自己和别人的生活增添一点美好和快乐。
          ⑥然而,谦和并不是毫无原则的退让,也不是有失尊严的顺从,我们必须做到谦和有度。
         ⑦谦和,如一幅淡雅的水墨画卷;谦和,似一篇清丽的婉约文章。(三)谦和,既美丽了自己,又悦目了他人。(选文有较大改动)

同类题5

 One billion teenagers and young adults around the world are in the face of losing their hearing by listening to loud music. This is according to the World Health Organization.

 Few things can make people happy and full of energy like good music. Many people believe louder is better if you are listening to rock and roll. But if you really listen to the music loudly, even really good music, it can hurt your hearing badly.

 If a person takes a subway to go from one place to the other for half an hour in the morning and a half an hour in the evening, and every day has to turn up the volume on his audio device because there is so much of noise of the train and everything around, and is listening to for one hour every day, his hearing is going to be hurt seriously in a few years, in a couple of years time, for sure.

 There can be many kinds of unsafe levels of sound. It depends on how loud the sound is and how long you listen to it. Unsafe can mean noise levels of 85 decibels for eight hours a day or 100 decibels for just 15 minutes.

 There are simple ways to protect people from unsafe sound levels. Young people who wear earplugs during concerts can enjoy music at 90 decibels as much as they can at 110 decibels. But earplugs may not look very cool. The fact that earplugs may look un-cool may be true today, but if there is nothing wrong with your hearing in the future may be true and wearing earplugs may actually be cool.

 Another common suggestion is to turn down the volume on your personal audio devices. The World Health Organization also advises young people to limit their use of such devices to less than one hour a day.

 Besides, the World Health Organization reminds people to use technology, such as smart audio devices keep listening levels safe.
