Natural Gas 1. Natural gas is produced from reservoirs deep beneath the earth’s surface. It is a fossil fuel, meaning that it is derived from organic material buried in the earth millions of years ago. The main component of natural gas is methane. 2. The popularity and use of clean natural gas has increased dramatically over the past 50 years as pipeline infrastructure has been installed to deliver it conveniently and economically to millions of residential, commercial and industrial customers worldwide. Today, natural gas services available in all 50 states in the U.S., and is the leading energy choice for fueling American homes and industries. More than 65 million American homes use natural gas. In fact, natural gas is the most economical source for home energy needs, costing one-third as much as electricity. In addition to heating homes, much of the gas used in the United States is used as a raw material to manufacture a wide variety of products, from paint to fibers for clothing, to plastics for healthcare, computing and furnishings. Natural gas is also used in a significant number of new electricity-generating power plants. 3. Natural gas is one of the safest and cleanest fuels available. It emits less pollution than other fossil fuel sources. When natural gas is burned, it produces mostly carbon dioxide and water vapour—the same substances emitted when humans exhale. Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted, making natural gas the cleanest burning fossil fuel of all. 4. The United States consumes about one-third of the world’s natural gas output, making it the largest gas-consuming region in the world. The U.S. Department of Energy Information Administration forecasts that natural gas demand will grow by more than 50 percent by 2025. 5. There are huge reserves of natural gas beneath the earth’s surface. The largest reserves of natural gas can be found in Russia, West and North Africa and the Middle East. LNG has been produced domestically and imported in the United States for more than four decades. Today, the leading imports of LNG are Japan, Korea, France and Spain. Paragraph 5 ______.
抬起头来做人 ①那一年,那个小男孩不过八九岁。一天,他拿着一张筹款卡回家,很认真地对妈妈说:“学校要筹款,每个学生都要叫人捐钱。” ②对小孩子来说,直接想到的“人”,就是自己的家长。 ③小男孩的妈妈取出5块钱,交给他,然后在筹款卡上签名。小男孩静静地看着妈妈签名,想说什么,却没开口。妈妈注意到了,问他:“怎么啦” ④小男孩低着头说:“昨天,同学们把筹款卡交给老师时,捐的都是100块、50块。” ⑤小男孩就读的是当地著名的“贵族学校”,校门外,每天都有小轿车等候放学的学生。小男孩的班级是排在全年级最前面的。班上的同学,不是家里捐献较多,就是成绩较好。当然,小男孩不属于前者。 ⑥那一天,小男孩说,不是想和同学比多,也不是自卑。他一向都认真对待老师交代的功课,这一次,也想把自己的“功课”做好。况且,学校还举行班级筹款比赛,他的班已领先了,他不想拖累整班。 ⑦妈妈把小男孩的头托起来说:“不要低头,要知道,你同学的家庭背景,非富则贵。我们必须量力而为,我们所捐的5块钱,其实比他们的500块钱还要多。你是学生,只要以自己的品学,尽力为校争光,就是对学校最好的贡献了。” ⑧第二天,小男孩抬起头,从座位走出去,把筹款卡交给老师。当老师在班上宣读每位同学的筹款成绩时,小男孩还是抬起头来。自此以后,小男孩在达官贵人、富贾豪绅的面前,一直抬起头来做人。 ⑨妈妈说的那一番话,深深地刻在小男孩心里。那是生平第一次,他面临由金钱来估量人的“成绩”的无言教育。非常幸运,就在这第一次,他学习到“捐”的意义,以及别人所不能“捐”到的、自己独一无二的价值。 文题“抬起头来做人”有何深刻含义试结合文章内容阐述这一文题中蕴含的哲理。
