节约能源 从我做起 自1831年英国科学家法拉第发现发电的原理以来,在不到两百年的时间里,电已经成了不可或缺的重要能源。有了它,我们可以使用电灯、电视机、空调、洗衣机、电冰箱、电脑等家用电器;有了它,城市的夜晚就会变得灯火通明,交通事故也减少了;有了它,工厂的机器为我们织出了一件件漂亮的衣裳。 不过,根据科学家的研究,用于发电的各种能源,如石油、煤炭、天然气等是有限的、不可再生的,终有用完的一天。依目前人类耗能的平均速度计算,2050年前后石油就会枯竭,即使是最丰富的太阳能,在数十亿年后也会耗尽。假如汽车熄了火,电灯不能亮了,电视没了图象与声音,电脑成了摆设,这是一幅多么可怕的景象,简直就是“世界末日”了。但是这种情景是完全可能发生的,虽然科学家不断研究地热、沼气、风能、太阳能、核能等,希望取代石油,可是一直没有突破性的发展。在新能源尚未开发成功,而旧能源又日渐枯竭的情况下,人们应当尽量减少能源的浪费。尤其是我国本身能源又有限,因此,就必须提高能源的使用效率。 节约能源,必须从身边开始,从自已做起,主要方法有: 一、 养成随手关灯的习惯。 二、 洗澡时动作要迅速,不边洗边玩。 三、 减少开电冰箱的次数。 四、 夏天空调器的温度不要调节器得太低。 五、 不要无休止地听音乐、玩电脑游戏、看电视等。 总之,在我们的生活中,衣、食、住、行等必须依靠能源,才能够制造和使用,所以我们的生活应该力求俭朴,减少任何不必要的浪费,才是节约能源的最好办法

The Ten CommandmentsMoses called together all the people of Israel and said to them, "People of Israel, listen to all the laws that I am giving you Learn them and be sure that you obey At Mount Sinai the Lord our God made a covenant, not only with our fathers, but with all of us who are living There on the mountain the Lord spoke to you face-to-face from the I stood between you and the Lord at that time to tell you what he said, because you were afraid of the fire and would not go up the "The Lord said, 'I'm the Lord your God, who rescued you from Egypt, where you were "Worship no god but ""Do not make for yourselves images of anything in heaven or on earth or in the water under the Do not bow down to any idol or worship it, for I am the Lord your God and I tolerate no I bring punishment on those who hate me and on their descendants down to the third and fourth But I show my love to thousands of generations of those who love me and obey my ""Do not use my name for evil purposes, for I, the Lord your God, will punish anyone who misuses my ""Observe the Sabbath and keep it holy, as I, the Lord your God, have commanded You have six days in which to do your work, but the seventh day is a day of rest dedicated to On that day no one is to work—neither you, your children, your slaves, your animals, nor the foreigners who live in your Your slaves must rest just as you Remember that you were slaves in Egypt, and that I, the Lord your God, rescued you by my great power and That is why I command you to observe the S""Respect your father and your mother, as I, the Lord your God, command you, so that all may go well with you and so that you may live a long time in the land that I am giving ""Do not commit ""Do not commit ""Do not ""Do not accuse anyone ""Do not desire another man's wife; do not desire his house, his land, his slaves, his cattle, his donkeys, or anything else that he " 注:《十诫》选自《旧约》的“申命记”(Deuteronomy)。中世纪以来,在基督教教会的极力推行下,“十诫”成为传统西方社会的道德准则,对西方文化产生了深远的影响。如果把它的具体内容同中国文化的传统价值观作一比较,我们不难发现它们之间存在着明显的异同。一方面,中西文化泾渭分明。前者表现出入世的、宽容的特征,如孔子不谈“怪、力、乱、神”,中国人“见神就拜”,相信“八仙过海,各显神通”;后者则表现出强烈的出世与排他倾向,这一点在第1—4诫中可以看出。另一方面,中西文化也具有共同的道德追求,第5—10诫可以为证。当然,当代中西文化均已发生很大变化,这一点,还望读者明察。
