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. Natural gas is stored deep ______. A. over the past 50 years B. beneath the earth’s surface C. by more than 50 percent D. for more than four decades E. as a raw material F. for home energy needs

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。 5肯定比500小,在第⑦段里,小男孩的妈妈为什么说“我们所捐的5块钱,其实比他们的500块钱还要多”呢

动物眼中的色彩 在正常人的眼中,能看到红的花,绿的树,蓝的天,白的云……人眼中的世界是多姿多彩五彩缤纷的。那么,大自然中其他动物眼中的色彩是什么样的呢科学家在此方面的研究取得了一定的成果。 研究证实,大多数哺乳动物是色盲。如我们常见的马、牛、羊、狗、猫等,几乎不会分辨颜色,反映到它们眼睛里的色彩,只有黑、白、灰三种颜色,如同我们看黑白电视一样单调。观看斗牛表演时,斗牛士用红色的斗篷向公牛挑战,人们会以为是红色激怒了它,而实际上是因为斗篷在公牛面前不断地摇晃,使它受到烦扰而发怒,如果换上别的颜色的斗篷,公牛也会出现同样的反应。狗也不能分辨颜色,它看景物就像一张黑白照片。狗追捕猎物除了靠四条腿外,主要靠嗅觉和听觉。我们人类的“近亲”猿猴也是色盲,天天过着平淡无奇的灰色生活。田鼠、家鼠、黄鼠、花鼠、松鼠、草原犬等也不能分辨颜色。 值得一提的是斑马,虽然它也是地地道道的色盲,但它却能利用色彩来保护自己。斑马和其他动物混在一起吃草,黑白条纹可以引起注意,因此在出现危险时,只要领头马一动,所有斑马会迅速逃走。当斑马奔跑时,黑白两色条纹的晃动使得捕食动物难以快速测定距离,斑马便可以借机安全逃脱。 但是,并不是所有的哺乳动物都是色盲。鹿对灰色的识别力最强,长颈鹿能分辨黄色、绿色和橘黄色。 鸟类的情况便好多了。除了某些过惯了夜生活的鸟类,如猫头鹰等,因为视网膜中没有锥状细胞,无法认色以外,许多飞禽都有色的感觉。鸟在高空飞行,颜色会帮助它们判断距离和形状,这样它们就能够抓住在高空飞行的虫子,在树枝上轻轻降落。鸟类的辨色能力却也有利于它们寻找配偶。雄鸟常用艳丽的羽毛吸引异性,试想,如果它们感受不到颜色,那雄鸟还有什么魅力呢 多数水生动物都有辨色能力。鲈鱼能感知颜色,生物学家用染成红色的幼虫喂它们,待其习惯后,改用红色羊毛喂它们,鲈鱼竟然照吃不误。龙虾、小虾以及爬行动物里的甲鱼、乌龟和蜥蜴等,也都有色的感觉。 昆虫虽然属低等动物,但是它们的辨色能力却比哺乳动物高明。 据悉,蜻蜓对色的视觉感最佳,其次是蝴蝶和飞蛾。苍蝇和蚊子也能看见颜色。苍蝇最讨厌蓝色,因而不愿接近蓝色的门窗、帐幔。蚊子能够辨别黄、蓝和黑色,并且偏爱黑色。勤劳的小蜜蜂生活在万紫千红的花丛中,却是红色盲,红色和黑色在蜜蜂眼里没有什么区别。蜜蜂能分辨青、黄、蓝三种颜色,但橙、黄、绿在它们看来是一样的,它们也搞不清蓝与紫有何不同。可是,蜜蜂能看见人所看不见的紫外线,并能把紫外线和各种深浅不同的白色和灰色准确地区别开来。 下列句子中的加点词语能去掉吗为什么 狗追捕猎物除了靠四条腿外,主要靠嗅觉和听觉。

Europa’s Watery under World Europa, one of Jupiter’s 63 known moons, looks bright and icy on the surface. But appearances can be deceiving: Miles within its cracked, frigid shell, Europa probably hides giant pools of liquid water. Where scientists find liquid water, they hope to find life as well. Since we can’t go diving into Europa’s depths just yet, scientists instead have to investigate the moon’s surface for clues to what lies beneath. In a new study, scientists investigated one group of strange ice patterns on Europa and concluded that the formations mark the top of an underground pool that holds as much water as the U. S. Great Lakes. Pictures of Europa, which is slightly smaller than Earth’s moon, clearly show a tangled, icy mishmash of lines and cracks known as "chaos terrains." These chaotic places cover more than half of Europa. For more than 10 years, scientists have wondered what causes the formations. The new study suggests that they arise from the mixing of vast underground stores of liquid water with icy material near the surface. For scientists who suspect that Europa also may be hiding life beneath its icy surface, the news about the new lake is exciting. "It would be great if these lakes harbored life, " Britney Schmidt, a planetary scientist who worked on the study, told Science News. "But even if they didn’t, they say that Europa is doing something interesting and active right now. " Schmidt, a scientist at the University of Texas at Austin, and her colleagues wanted to know how chaos terrains form. Since they couldn’t rocket to Europa to see for themselves, they searched for similar formations here on Earth. They studied collapsed ice shelves in Antarctica and icy caps on volcanoes in Iceland. Those features on Earth formed when liquid water mixed with ice. The scientists now suspect something similar might be happening on Europa: that as water and ice of different temperatures mingle and shift, the surface fractures. This would explain the jumbled ice sculptures. "Fracturing catastrophically disrupts the ice in the same way that it causes ice shelves to collapse on Earth, " Schmidt told Science News. She and her team found that the process could be causing chaos terrains to form quickly on Europa. The new study suggests that on this moon, elements such as oxygen from the surface blend with the deep bodies of water. That mixture may create an environment that supports life. The strange ice patterns on Europa are formed as a result of a mixing underground water pool.
