1、本文格式為Word版，下載可任意編輯 初一年級(jí)英語(yǔ)探索月球奧秘的探索月球 月球又稱“月亮”。在望遠(yuǎn)鏡研發(fā)之前，古代的人們只能在晴朗的夜晚，用眼睛景仰皎潔的明月?？吹皆铝镣庥^有明有暗，外形特殊，于是人們就編出如嫦娥奔月、吳剛伐桂、玉免搗藥等美觀神話。古希臘人那么把月球看作美觀的狩獵女神阿爾忒彌斯，并且把女神狩獵時(shí)從不離身的銀弓作為月球的天文符號(hào)。 The moon is also called the moon. Before the invention of telescope, ancient people could only look up at the bright moon with

2、 their eyes on a clear night. Seeing the moons surface is bright and dark, and its shape is strange, people have made up Beautiful myths suc()h as Change running to the moon, Wu Gang cutting the laurel, Yu Mian tampering with medicine and so on. The ancient Greeks regarded the moon as Artemis, the b

3、eautiful hunting goddess, and regarded the silver bow that the goddess never left when hunting as the astronomical symbol of the moon. 月球根本上沒有水，也就沒有地球上的風(fēng)化、氧化和水的腐蝕過(guò)程，也沒有聲音的傳播，四處是一片安寧的世界。 Basically, there is no water on the moon, so there is no weathering, oxidation and water corrosion process on the

4、earth, and there is no sound transmission. There is a silent world everywhere. 月球上幾乎沒有大氣，因而月球上的晝夜溫差很大。白天，在陽(yáng)光垂直照射的地方，溫度高達(dá)127； 夜晚溫度可低到-183。由于沒有大氣的阻隔，使得月面上日光強(qiáng)度比地球上約強(qiáng)13左右；紫外線強(qiáng)度也比地球外觀強(qiáng)得多。由于月球大氣少，因此在月面上會(huì)見到大量特殊的現(xiàn)象，如月球上的天空呈暗黑色，太陽(yáng)光照射是筆直的，日光照到的地方很亮堂；照不到的地方就很暗。因此才會(huì)看到的月亮外觀有明有暗。由于沒有空氣散射光線，在月球上星星看起來(lái)也不再閃爍了。 There

5、is almost no atmosphere on the moon, so the temperature difference between day and night on the moon is very large. In the daytime, the temperature is as high as 127 in the place where the sun shines vertically; at night, the temperature can be as low as - 183 . Due to the absence of atmospheric bar

6、rier, the intensity of sunlight on the moon is about 1 / 3 stronger than that on the earth, and the intensity of ultraviolet is much stronger than that on the earth. Due to the lack of atmosphere on the moon, many strange phenomena can be seen on the surface of the moon, such as the dark sky on the

7、moon, the straight sunlight, the bright place where the sun shines, and the dark place where it cant. Therefore, the surface of the moon is bright and dark. Since there is no air to scatter light, the stars on the moon no longer seem to twinkle. 月面上四處是袒露的巖石和環(huán)形山的側(cè)影。整個(gè)月面籠罩著一層碎石粒和浮土。從地球上看到的月球外觀有亮堂的區(qū)域和暗

8、灰色片面。原來(lái)亮堂的片面是月球外觀的山區(qū)和高地，暗灰色片面是月球外觀的平原月球在繞地球運(yùn)動(dòng)的過(guò)程中，還要跟著地球一起繞太陽(yáng)運(yùn)動(dòng)。這就是說(shuō)，月球繞地球運(yùn)動(dòng)一周后，再回到的空間位置已不是原啟程點(diǎn)了。由此可見，月球在運(yùn)動(dòng)過(guò)程中還要參與多種系統(tǒng)的運(yùn)動(dòng)。月球的運(yùn)動(dòng)和其他天體一樣，月球也處于永恒的運(yùn)動(dòng)之中。月球除東升西落外，它每天還相對(duì)于恒星自西向東平均移動(dòng)13多，因此，月亮每天升起來(lái)的時(shí)間，都比前一天約遲50分鐘。月亮的東升西落是地球自轉(zhuǎn)的反映； 而自西向東的移動(dòng)卻是月亮圍繞地球公轉(zhuǎn)的結(jié)果。月亮繞地球公轉(zhuǎn)一周叫做一個(gè)“恒星月”，平均是27天7小時(shí)43分11秒。月亮繞地球公轉(zhuǎn)的同時(shí)，它本身也在自轉(zhuǎn)。月亮的

9、自轉(zhuǎn)周期和公轉(zhuǎn)周期是相等的，即1：1，月球繞地球一周的時(shí)間為也就是它自轉(zhuǎn)的周期。 The moon is covered with exposed rocks and silhouettes of craters. The whole moon surface is covered with a layer of broken stone and floating soil. The surface of the moon seen from the earth has bright areas and dark gray parts. It turns out that the bright

10、 part is the mountains and highlands on the moons surface, and the dark gray part is the plain on the moons surface. In the process of the moons movement around the earth, it also moves around the sun with the earth. That is to say, after the moon moves around the earth for a week, the space positio

11、n returned to is not the original starting point. It can be seen that the moon is also involved in the movement of various systems. Like other celestial bodies, the moon is in perpetual motion. In addition to rising in the East and falling in the west, the moon moves 13 more than the star from the w

12、est to the East on average every day. Therefore, the rising time of the moon every day is about 50 minutes later than the previous day. The rise and fall of the moon in the East is the reflection of the earths rotation, while the movement from the west to the East is the result of the moons rotation around the earth. The moons orbit around the earth is called a stellar moon, with an average of 27 days, 7 hours, 43 minutes and 11 seconds. Wh
