慘象，已使他目不忍視了；流言，尤使他而不忍聞了，他還有什么話可說呢？他懂得成敗英雄之所以默無聲息的緣由了。沉默啊，沉默??！不在沉默中勝出，就在沉默中淘汰。

真正的學(xué)生敢于直面困苦的高中，敢于正視頻繁的考試，這是怎樣的哀痛者和幸福著？然而進(jìn)化又常常為老師設(shè)計，以早晨的歌聲來洗滌睡意，僅僅留下苦悶的講義和長長的筆記，在這樣苦悶的講義和長長的筆記中，又給我暫得忍耐，維持著這似人非人的生活，我不知道這樣的生活何時是一個盡頭？我們還在這樣的世上活著，我也早覺得有點(diǎn)干什么的必要了，離9月1號已有40多天了，忘卻了的救世主，快要降臨了罷，我正有干點(diǎn)什么的必要了。imitatethispassageandrewriteanewonePlasticBagsorClothBags?ThefollowingwordsmayhelpyouOverthepastcentury,...havebecomecommon...Recently,however,...havebeenfindingthattheycancausedamageto..
