導(dǎo)語(yǔ)：水是生命之源，這的確是最中肯的評(píng)價(jià)，自從生命在水中形成的第一天起，水在生命體中起的作用就沒有發(fā)生過改變。下面是yuwenmi小編為大家整理的優(yōu)秀英語(yǔ)演講稿，歡迎閱讀與借鑒，謝謝!

　　The role of water

　　Water is very important to us. if you dont have water for three days, you will die. we can use water for flowers, swimming, washing and many different things. we use it to cook, make electricity, put out fires and so on. we use millions of liters of water every day.

　　Do you know how does the water come to your home? it travels through water pipes. some are long and wide but some are short and narrow. then the water travels through the water pipes to the reservoirs. then it travels through the water pipes to the river and to the special factories that purify the water. when the water is purified, we can drink it. please dont leave garbage in the water on which we line, and keep the water clean.

　　【參考譯文】

　　水的作用

　　水對(duì)我們很重要。如果你沒有水三天，你會(huì)死。我們可以用水來花，游泳，洗滌和許多不同的東西。我們用它做飯，發(fā)電，撲滅火災(zāi)等。我們每天使用數(shù)百萬(wàn)公升的`水。

　　你知道水是怎么來你家的嗎?它穿過水管。有些長(zhǎng)而寬，有些短而窄。然后水通過水管流向水庫(kù)。然后它通過水管到河流和特殊工廠凈化水。水凈化后我們就可以喝了。請(qǐng)不要把垃圾放在我們系的水里，保持水的清潔。
