3.地球的英文介绍（简单一些）
earth id the third planet in distance outward from the Sun.
Believed to be about 4.6 billion years old, it is some 92,960,000 mi (149,600,000 km) from the Sun. It orbits the Sun at a speed of 18.5 mi (29.8 km) per second, making one complete revolution in 365.25 days. As it revolves, it spins on its axis, rotating once every 23 hours 56 minutes 4 seconds. The fifth largest planet of the solar system, it has an equatorial circumference of 24,902 mi (40,076 km). Its total surface area is roughly 197,000,000 sq mi (509,600,000 sq km), of which about 29% is land. Earth’s atmosphere consists of a mixture of gases, chiefly nitrogen and oxygen. Its only natural satellite, the Moon, orbits the planet at a distance of about 238,860 mi (384,400 km). Earth’s surface is traditionally subdivided into seven continental masses: Africa, Antarctica, Asia, Australia, Europe, North America, and South America. These continents are surrounded by the so-called World Ocean, which is broken down into three major bodies: the Atlantic, Pacific, and Indian oceans. Broadly speaking, Earth’s interior consists of two regions: a core composed largely of molten, iron-rich metallic alloy; and a rocky shell of silicate minerals comprising both the mantle and crust (See also Moho; lithosphere). Fluid motions in the electrically conductive outer core generate a magnetic field around Earth that is responsible for the Van Allen radiation belts. According to the theory of plate tectonics, the crust and upper mantle are divided into a number of large and small plates that float on and travel independently of the lower mantle. Plate motions are responsible for continental drift and seafloor spreading and for most volcanic and seismic activity on Earth.
4.关于地球的资料用英语介绍六十词左右
The area of desert in the world is growing every year. Many parts of the world which once had large populations and produced plenty of crops, have become deserts. Dunhuang in China, deep in the heart of the Gebi Desert, was once a great city.
Cattle are one cause of the problem. In good years, famers increase the numbers of their cattle. Then one year, the rains fail to come. The farmers do not want to kill any of their cattle, so the cattle eat ail the grass and anything that grows on poorer land. If this continues for several years, the grass never grows again and the land becomes a desert. One suggested answer is for farmers to limit the numbers of their cattle.
Another problem is that good soil is gradually lost. When trees are cut down, there is nothing to hold the soil in place on the hillside. So when if rains, the soil is washed down the hills and into the rivers. Strong winds can also blow away the valuable soil that lies on the top of the fields.

7.世界地球日英文资料
Background Information: Earth Day April 22 is Earth Day, our country this year to determine the theme of “treat the earth, protect the environment.” Earth Day originated in the U.S.. In 1969, Democratic Senator Gaylord Nelson proposed the park in the U.S. schools held workshops on environmental issues, and the following year on April 22 as “Earth Day.” Then 25-year-old Harvard Law School student Dennis will soon be the proposal throughout the United States into a large-scale community-based activities, specific ideas, and get enthusiastic support of many young students. April 22, 1970, the United States for the first time held a massive “Earth Day”, around 2,000 people participated, the United States since World War II, was hailed as the largest social activities.April 22, 1990, more than 140 countries around the world, 200 million people around the same time held a variety of promotional activities, the theme is how to improve the overall global environment. The event made people more clearly recognize, as the global industry continues to develop, ozone layer destruction, and the resulting global climate change, is becoming a direct threat to the global problem of human existence. The activities of the United Nations approval, then, every year on April 22 was identified as the “World Earth Day.” Currently, the more prominent environmental issues, soil erosion, desertification, pollution of freshwater resources. According to UN figures released by the 20th century, the world’s forest area 90 at an average annual rate of 2.4% reduction in the past 10 years, the world’s total forest area of the disappearance of 94 million hectares. At present nearly half the land surface and more than one billion people affected by desertification. Pollution in the atmosphere, from 1965 to 1998, global carbon dioxide emissions doubled. The world is facing a water crisis in many countries: 12 million people short of water, 3.0 billion people lack water sanitation Each year from 3,000,000 to 400 million deaths and water-related diseases. By 2025, the water crisis will be spread to 48 countries, 35 million are trapped by the water.Earth Day activities held to raise human caring for the earth, protect the home in promoting the coordinated development of resource development and environmental protection. My 90 years from the 20th century, the annual April 22 Earth Day celebrations are held. (END) 中文对照翻译 背景资料：世界地球日 4月22日是世界地球日，我国今年确定的主题是“善待地球，保护环境”。
地球日起源于美国。1969年，民主党参议员盖洛德·尼尔森提议，在美国各校园内举办有关环境问题的讲习会，并将次年的4月22日作为“地球日”。
当时25岁的哈佛大学法学院学生丹尼斯·海斯很快将这一提议变成了一个在全美各地展开大规模社区性活动的具体构想，并得到很多青年学生的热烈支持。1970年4月22日，美国首次举行了声势浩大的“地球日”活动，各地约2000万人参加，当时被誉为二战以来美国规模最大的社会活动。
1990年4月22日，全世界140多个国家、2亿多人同时在各地举行了多种多样的宣传活动，主题是如何改善全球整体环境。这次活动使人们更加清醒地认识到，随着全球工业的不断发展，大气臭氧层遭到破坏，由此带来的全球气候异常变化，正在成为直接威胁人类生存的世界性问题。
这项活动得到了联合国的首肯，其后，每年的4月22日被确定为“世界地球日”。 目前，世界环境问题越发突出，水土流失、土地沙漠化、淡水资源污染等。
据联合国公布的数字表明，20世纪90年代全球森林面积以平均每年2.4%的速度缩减，近10年来，全球消失的森林总面积达到9400万公顷。目前全球近二分之一的陆地表面和10亿以上人口受到沙漠化影响。
在大气污染方面，从1965至1998年，全球二氧化碳排放量翻了一番。目前世界上许多国家正面临水资源危机：12亿人用水短缺，30亿人缺乏用水卫生设施，每年有300万到400万人死于和水有关的疾病。
到2025年，水危机将蔓延到48个国家，35亿人为水所困。 世界地球日活动的举办，以期唤起人类爱护地球、保护家园的意识，促进资源开发与环境保护协调发展。
我国从20世纪90年代起，每年4月22日都举办世界地球日纪念活动。（完）。
8.有关于地球的英文故事
资料多。
帮你找点常识性的吧。Earth is the only planet whose English name does not derive from Greek/Roman mythology. The name derives from Old English and Germanic. There are, of course, hundreds of other names for the planet in other languages. In Roman Mythology, the goddess of the Earth was Tellus – the fertile soil (Greek: Gaia, terra mater – Mother Earth). It was not until the time of Copernicus (the sixteenth century) that it was understood that the Earth is just another planet. Mir space station and Earth’s limb Earth, of course, can be studied without the aid of spacecraft. Nevertheless it was not until the twentieth century that we had maps of the entire planet. Pictures of the planet taken from space are of considerable importance; for example, they are an enormous help in weather prediction and especially in tracking and predicting hurricanes. And they are extraordinarily beautiful. The Earth is divided into several layers which have distinct chemical and seismic properties (depths in km): 0- 40 Crust 40- 400 Upper mantle 400- 650 Transition region 650-2700 Lower mantle 2700-2890 D” layer 2890-5150 Outer core 5150-6378 Inner core The crust varies considerably in thickness, it is thinner under the oceans, thicker under the continents. The inner core and crust are solid; the outer core and mantle layers are plastic or semi-fluid. The various layers are separated by discontinuities which are evident in seismic data; the best known of these is the Mohorovicic discontinuity between the crust and upper mantle. Most of the mass of the Earth is in the mantle, most of the rest in the core; the part we inhabit is a tiny fraction of the whole (values below x10^24 kilograms): atmosphere = 0.0000051 oceans = 0.0014 crust = 0.026 mantle = 4.043 outer core = 1.835 inner core = 0.09675The core is probably composed mostly of iron (or nickel/iron) though it is possible that some lighter elements may be present, too. Temperatures at the center of the core may be as high as 7500 K, hotter than the surface of the Sun. The lower mantle is probably mostly silicon, magnesium and oxygen with some iron, calcium and aluminum. The upper mantle is mostly olivene and pyroxene (iron/magnesium silicates), calcium and aluminum. We know most of this only from seismic techniques; samples from the upper mantle arrive at the surface as lava from volcanoes but the majority of the Earth is inaccessible. The crust is primarily quartz (silicon dioxide) and other silicates like feldspar. Taken as a whole, the Earth’s chemical composition (by mass) is: South America by Galileo 34.6% Iron 29.5% Oxygen 15.2% Silicon 12.7% Magnesium 2.4% Nickel 1.9% Sulfur 0.05% TitaniumThe Earth is the densest major body in the solar system. The other terrestrial planets probably have similar structures and compositions with some differences: the Moon has at most a small core; Mercury has an extra large core (relative to its diameter); the mantles of Mars and the Moon are much thicker; the Moon and Mercury may not have chemically distinct crusts; Earth may be the only one with distinct inner and outer cores. Note, however, that our knowledge of planetary interiors is mostly theoretical even for the Earth. Unlike the other terrestrial planets, Earth’s crust is divided into several separate solid plates which float around independently on top of the hot mantle below. The theory that describes this is known as plate tectonics. It is characterized by two major processes: spreading and subduction. Spreading occurs when two plates move away from each other and new crust is created by upwelling magma from below. Subduction occurs when two plates collide and the edge of one dives beneath the other and ends up being destroyed in the mantle. There is also transverse motion at some plate boundaries (i.e. the San Andreas Fault in California) and collisions between continental plates (i.e. India/Eurasia). There are (at present) eight major plates: North American Plate – North America, western North Atlantic and Greenland Earth’s Plate Boundaries delineated by earthquake epicenters South American Plate – South America and western South Atlantic Antarctic Plate – Antarctica and the “Southern Ocean” Eurasian Plate – eastern North Atlantic, Europe and Asia except for India African Plate – Africa, eastern South Atlantic and western Indian Ocean Indian-Australian Plate – India, Australia, New Zealand and most of Indian Ocean Nazca Plate – eastern Pacific Ocean adjacent to South America Pacific Plate – most of the Pacific Ocean (and the southern coast of California!) There are also twenty or more small plates 。
