惨象，已使他目不忍视了；流言，尤使他而不忍闻了，他还有什么话可说呢？他懂得成败英雄之所以默无声息的缘由了。沉默啊，沉默啊！不在沉默中胜出，就在沉默中淘汰。

真正的学生敢于直面困苦的高中，敢于正视频繁的考试，这是怎样的哀痛者和幸福着？然而进化又常常为老师设计，以早晨的歌声来洗涤睡意，仅仅留下苦闷的讲义和长长的笔记，在这样苦闷的讲义和长长的笔记中，又给我暂得忍耐，维持着这似人非人的生活，我不知道这样的生活何时是一个尽头？我们还在这样的世上活着，我也早觉得有点干什么的必要了，离9月1号已有40多天了，忘却了的救世主，快要降临了罢，我正有干点什么的必要了。imitatethispassageandrewriteanewonePlasticBagsorClothBags?ThefollowingwordsmayhelpyouOverthepastcentury,...havebecomecommon...Recently,however,...havebeenfindingthattheycancausedamageto..
