“保護(hù)地球”國旗下講話
我曾經(jīng)獨自漫步于瀏陽河的街頭，瀏陽河略顯蒼傷。河面上的層層漣漪上漂浮著大大小小、形形色色的垃圾袋，慘不忍睹。昔日的潺潺流水怎么成為了瀏陽河的呻吟與哭訴呢？瀏陽河是我們的母親河，她給了我們水源，給了我們美麗的環(huán)境，也給了我們清新的空氣?？晌覀冇质窃鯓訉Υ约旱哪赣H的呢？這只是我們生活中一個真實確切的片段。再到日本的海嘯。這場日本史上最強(qiáng)地震，令我十分震撼?？吹诫娨暽?、報紙上人們一張張痛苦的臉，使我十分痛心。電視上的一段錄像中，一座20層高的大廈左右搖晃了3分鐘。不過有驚無險，那座大廈制材堅固，沒有倒下。這場強(qiáng)烈的地震，也給太平洋帶來了強(qiáng)烈的震波。地球調(diào)節(jié)成了振動模式，人們因為對保護(hù)環(huán)境的無視，遭受到了災(zāi)難的蹂躪、踐踏，世界的那一片青山綠水還會存在嗎？我們眼前的彩色時間究竟什么時候會變得黑白？偉大的無產(chǎn)階級革命導(dǎo)師恩格斯說過：“我們連同我們的血、肉、頭腦一起都屬于自然界，存在于自然界?！?/p>
