第一篇：关于时间的演讲稿三分钟
尊敬的老师、亲爱的同学们：
大家好！
一部探讨人类命运的影片《流浪地球》引起了大家的热议，放眼宇宙的宏伟旷野，波澜壮阔的人类迁徙，是否都令你印象深刻？然而，你是否知道？作为一座年均生活垃圾产生量超过万吨，建筑垃圾申报量达到余万吨的超大城市――也正面临城市精细化管理和环境保护的巨大挑战。
那么生活中的垃圾该如何进行分类呢？蓝色的垃圾桶收集可回收物。比如平时的废纸张，废玻璃制品，废衣物，塑料瓶等都是可再生资源。红色的垃圾桶收集有害垃圾。比如废电池、废灯管、油漆、过期药品等都是对人体或环境有害的垃圾。像过期食品，瓜皮果核等容易腐烂的垃圾需放在棕色的湿垃圾桶内。除了上述垃圾之外，其他生活废物，放在黑色的干垃圾桶，统一回收。玻璃是最容易回收利用的产品，回收利用旧玻璃可以节约大量的能源，同时也减少了开采矿石带来的环境破坏。回收利用纸，对环境的保护意义巨大，用废纸每制造1立方米的再生纸，就等于保护了17棵大树。塑料回收后，不但可以制造成再生塑料产品，还可以变成原油，再从中提炼出柴油、汽油，供我们使用。垃圾分类，看似小事情，实则大文明。我们必须迅速行动起来，自觉分类投放垃圾，并努力通过减少一次性用品的使用、增加二手物品的利用、优先选择再生物品等方式减少垃圾产生量！同学们，让我们共同行动起来，从身边做起，从小事做起，积极参与生活垃圾分类和减量工作，努力捍卫我们的蓝天、碧水、净土，早日将建成令人向往和具有世界影响力的国际化大都市！最后我向大家呼吁：洁净环保千万条，垃圾分类第一条，干湿有害分好类，美好习惯为社会。
谢谢大家！
第二篇：珍惜时间一分钟演讲稿
时间就像是海绵里的水，只要用力挤，总还是有的。——题记
云朵散了，有再聚的时候;太阳落了，有再升的时候;春天去了，有再来的时候。我们的日子为什么一去不复返?我们的时间为什么如此地飞逝呢?
夜晚，躺在床上，透过层层玻璃，皎洁月亮洒下迷人的光辉，转眼间，它变得无影无踪。月亮它会飞啊，逃也似的离开我的视线。于是——奔跑时，时间从脚步声中过去;叹息时，时间从唉声叹气中过去;读书时，时间从密密麻麻的文字中过去;思考时，时间又从满脑的问号中过去……
“一寸光阴一寸金，寸金难买寸光阴。”时间是那样珍贵，学习中一定要珍惜时间。每天早晨，总是要加速赶往学校，只为能使早读增添几分时间。课堂上，认真听讲，把握每分每秒学习，不要拖拖欠欠，让“明日复明日，明日何其多”成为现实。晚上，以正确率高，及最快的速度完成作业，像“时间就像是海绵里的水，只要用力挤，总还是有的”那样匀出时间进行复习、预习，并做一些自己热爱的事情。完美的一天就这样充分利用价值地过去了。
“时间就是性命，无端的空耗别人的时间，是无异于谋财害命的”。生活中也要珍惜时间。清晨，是一天中最美好的时刻，“良好的开端是成功的一半”，一定要合理规划时间，做有氧运动，进行晨读。接下来，需要做一些有意义的事情，不要空耗时间，浪费时间，让生活留下遗憾。
如果你热爱生活，如果你热爱生命，就请你珍惜时间，把握好每分每秒。
第三篇：珍惜时间英语演讲稿
my brother-in-law opened the bottom drawer of my sisters bureau and lifted out a tissue-wrapped package. this, he said, is not a slip. this is lingerie. he discarded the tissue and handed me the slip.
it was exquisite, silk, handmade and trimmed with a cobweb of lace. the price tag with an astronomical figure on it was still attached.
jan bought this the first time we went to new york, at least 8 or 9 years ago. she never wore it. she was saving it for a special occasion.
well, i guess this is the occasion.
he took the slip from me and put it on the bed, with the other clothes we were taking to the mortician. his hands lingered on the soft material for a moment, then he slammed the drawer shut and turned to me, dont ever save anything for a special occasion. every day you re alive is a special occasion.
i remembered those words through the funeral and the days that followed when i helped him and my niece attend to all the sad chores that follow an unexpected death. i thought about them on the plane returning to california from the midwestern town where my sisters family lives. i thought about all the things that she hadnt seen or heard or done. i thought about the things that she had done without realizing that they were special.
im still thinking about his words, and theyve changed the weeds in the garden. im spending more time with my family and friends and less time in committee meetings. whenever possible, life should be a pattern of experience to savour, not endure. im trying to recognize these moment now and cherish them.
im not saving anything; we use our good china and crystal for every special. event such as losing a pound, getting the sink unstopped, the first camellia blossom… i wear my good blazer to the market if i feel like it. my theory is if i look prosperous, i can shell out $28. 49 for one small bag of groceries without wincing. im not saving my good perfume for special parties; clerks in hardware stores and tellers in banks have noses that function as well as my party going friends.
someday and one of these days are losing their grip on my vocabulary. if its worth seeing or hearing or doing, i want to see and hear and do it now. im not sure what my sister wouldve done had she know that she wouldnt be here for the tomorrow we all take for granted.
i think she would have called family members and a few close friends. she might have called a few former friends to apologize, and mend fences for past squabbles. i like to think she would have gone out for a chinese dinner, her favorite food. im guessing. ill never know.
its those little things left undone that would make me angry if i knew that my hours were limited. angry because i put off seeing good friends whom i was going to get in touch with someday. angry because i hadnt written certain letters that i intended to write one of these days. angry and sorry that i didnt tell my husband and daughter often enough how much i truly love them.
im trying very hard not to put off, hold back, or save anything that would add laughter and luster to our lives. and every morning when i open my eyes, i tell myself that every day, every minute, every breath truly, is... a gift from god.
第四篇：关于时间的演讲稿三分钟
尊敬的老师，亲爱的同学们：
大家好！
我的家乡在大洲，那是一个偏僻的小山村。虽然交通不便，也没有新安江的热闹繁华，但这里的一点一滴都让我难以忘怀！
暑假的一天，我跟着爸爸妈妈回到了半年未回的家乡。一进村口，就看到那笔直笔直的水泥路通往村中心，印象中的那条晴天一身灰，雨天一身泥的崎岖不平的黄泥路已消失得无影无踪。看着我吃惊的样儿，妈妈说：“这只是小惊喜，你可要做好心理准备。”
踏着平坦的水泥路，我们来到了村中心。我不由眼前一亮，原来那些残旧的平房不见了，只见一座座新修的砖瓦房拔地而起，房子四周，绿树成阴，鲜花盛开，真是美不胜收。
我们走着走着，就来到了大会堂，只见天花板上整齐排列着崭新的吊扇，大大的窗户，高高的舞台，一排排整齐的梯形座位出现在眼前，听爸说可坐五六百的观众。村里有任何隆重的节日都放在这庆祝，以前看个戏那种风吹雨淋的日子，再也不用担心了。
家乡的变化真大！我爱我的家乡！
谢谢。
第五篇：关于时间的演讲稿三分钟
亲爱的同学们，老师们：
早上好！
每个人都拥有青春，不要用化妆品去追求青春，因为青春的魅力，总是在自然中表现。人生最值得你回忆的是你的青春，最值得你留恋的也是你的青春。在多彩的人生中，青春是驶向成熟的一个港湾，是人生旅途中的一个驿站，有人称他为花季。既然是花季又何必带着那么多伤感与忧虑往来于花丛呢？在这莺歌燕舞的季节，我们向青春致敬。思绪聚焦在青春的烦恼上，我们或许难以释怀，青春的烦恼是成长的印迹，我们无需回避。青春可为烦恼落泪，但青春需要无悔。
青春之弦，奏得响亮，青春的烦恼，不该成为优美曲调中的杂音，悲伤的时候，求一份释然；气愤的时候，求一份平静；痛苦的时候，心存感恩地面对，让春日的微风拂过心灵，除去尘埃，让泪撒，让笑留，让我们为中学的生活欢呼与拼搏。浮生若梦，为欢几何，让我们释怀解开烦恼，青春不常在，年华似水流，让我们珍惜今天的拥有，去创造未来的辉煌。
青春是一面镜子，如果你想看到自己美丽的面孔就必须努力！
青春，靓丽而又短暂，只有抓住她并好好珍惜，你的人生才会无比灿烂。青春之舟，只有鼓起时代的风帆，才能在岁月的长河上永不停息地航行。拥有青春，不等于拥有一切。只有在拥有青春的同时，不懈努力、顽强拼搏，才能拥有美好人生。
谢谢。
