【正文】 恰從本質(zhì)上體現(xiàn)一個人的思想品質(zhì)。事實上，良好的行為習(xí)慣是保證我們良好學(xué)習(xí)的前提，也是樹立健康人格的基礎(chǔ)。在學(xué)校沒有良好的行為習(xí)慣的同學(xué)就目無紀(jì)律，不講衛(wèi)生，擾亂整個學(xué)校的學(xué)習(xí)環(huán)境。相反，如果我們養(yǎng)成了文明的行為習(xí)慣，學(xué)習(xí)環(huán)境就是良好的、有序的。我們知道：一個學(xué)校的學(xué)生具有良好的文明行為習(xí)慣，才能構(gòu)建出優(yōu)良的學(xué)習(xí)環(huán)境，創(chuàng)造出優(yōu)良的學(xué)習(xí)成績?，F(xiàn)在，我們正處于人生中最關(guān)鍵的探索時期，在這個時期的所作所為，將潛移默化的影響到我們自身的心理素質(zhì)，而文明的行為就在幫助我們提高自身的心理素質(zhì)，同時也完善了自身的道德品質(zhì)，如果我們不在此時，抓好自身的道德素質(zhì)建設(shè)，那我們縱然擁有了豐富的科學(xué)文化知識，于人于己于社會又有何用呢，所以，我們應(yīng)該先成人，后成材，不要做一部單純掌握一些知識技能的機器，而要成為一個身心和諧發(fā)展的人。文明就是我們素質(zhì)的前沿，擁有文明，那我們就擁有了世界上最為寶貴的精神財富。無數(shù)事例表明，走向事業(yè)輝煌，開創(chuàng)成功人生的關(guān)鍵，是品德高尚的情操。代表民族未來的我們，需要學(xué)習(xí)繼承的東西有很多很多，然而最基本的問題是，我們究竟要以什么樣的精神風(fēng)貌，什么樣的思想品質(zhì)，什么樣的道德水準(zhǔn)，去接過人類文明的接力棒。同學(xué)們，我們播下一個動作，使收獲一個習(xí)慣。播下一個習(xí)慣，使收獲一個品格。文明已被人們放在心里的一個重要位置，時時刻刻在與文明交談，千萬不要把文明行為習(xí)慣看作小事。每個人的舉手投足之間都傳遞著豐富的文明信息，讓我們從現(xiàn)在做起，從自己做起，從點點滴滴的小事做起，養(yǎng)成良好的文明習(xí)慣，做文明學(xué)生，管住我們的口，不隨地吐痰。管住我們的手，不亂扔垃圾。管住我們我們的腳，不踐踏花草。我相信，我們?nèi)w師生經(jīng)過努力，一定會營造成一個寧靜、有序、有著良好學(xué)習(xí)環(huán)境的校園。謝謝大家。初二英語三分鐘演講稿someone said “we are reading the first verse of the first chapter of a book, whose pages are infinite”. i don?t know who wrote these words, but i?ve always liked them as a reminder that the future can be anything we want it to be. we are all in the position of the farmers. if we plant a good seed ,we reap a good harvest. if we plant nothing at all, we harvest nothing at all.we are young. “how to spend the youth?” it is a meaningful question. to answer it, first i have to ask “what do you understand by the word youth?” youth is not a time of life, it?s a state of mind. it?s not a matter of rosy cheeks, red lips or supple knees. it?s the matter of the will. it?s the freshness of the deep spring of life.youth means a temperamental predominance of courage over timidity of the appetite , for adventure over the love of ease. this often exists in a man of 60 more than a boy of 20 . nobody grows old merely by a number of years . we grow old by deserting our ideals. years wrinkle the skin , but to give up enthusiasm wrinkles the soul . worry , fear , self –distrust bows the heart and turns the spirit back to dust .whether 60 of 16 , there is in every human being ?s heart the lure of wonders, the unfailing childlike appetite of what?s next and the joy of the game of living . in the center of your heart and my heart there?s a wireless station : so long as it receives messages of beauty , hope ,cheer, courage and power from men and from the infinite, so long as you are young .a poet said “to see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and etern
