探索月球奥秘的作文
<p>月球又称“月亮”。在望远镜发明之前，古代的人们只能在晴朗的夜晚，用眼睛仰望皎洁的明月。看到月亮表面有明有暗，形状奇特，于是人们就编出如嫦娥奔月、吴刚伐桂、玉免捣药等美丽神话。古希腊人则把月球看作美丽的狩猎女神阿尔忒弥斯，并且把女神狩猎时从不离身的银弓作为月球的天文符号。</p><p><span word="The">The</span> <span word="moon">moon</span> <span word="is">is</span> <span word="also">also</span> <span word="called">called</span> <span word="the">the</span> <span word="moon">moon</span>. <span word="Before">Before</span> <span word="the">the</span> <span word="invention">invention</span> <span word="of">of</span> <span word="telescope">telescope</span>, <span word="ancient">ancient</span> <span word="people">people</span> <span word="could">could</span> <span word="only">only</span> <span word="look">look</span> <span word="up">up</span> <span word="at">at</span> <span word="the">the</span> <span word="bright">bright</span> <span word="moon">moon</span> <span word="with">with</span> <span word="their">their</span> <span word="eyes">eyes</span> <span word="on">on</span> <span word="a">a</span> <span word="clear">clear</span> <span word="night">night</span>. <span word="Seeing">Seeing</span> <span word="the">the</span> <span word="moon">moon</span>'<span word="s">s</span> <span word="surface">surface</span> <span word="is">is</span> <span word="bright">bright</span> <span word="and">and</span> <span word="dark">dark</span>, <span word="and">and</span> <span word="its">its</span> <span word="shape">shape</span> <span word="is">is</span> <span word="strange">strange</span>, <span word="people">people</span> <span word="have">have</span> <span word="made">made</span> <span word="up">up</span> <span word="Beautiful">Beautiful</span> <span word="myths">myths</span> <span word="such">such</span> <span word="as">as</span> <span word="Chang">Chang</span>'<span word="e">e</span> <span word="running">running</span> <span word="to">to</span> <span word="the">the</span> <span word="moon">moon</span>, <span word="Wu">Wu</span> <span word="Gang">Gang</span> <span word="cutting">cutting</span> <span word="the">the</span> <span word="laurel">laurel</span>, <span word="Yu">Yu</span> <span word="Mian">Mian</span> <span word="tampering">tampering</span> <span word="with">with</span> <span word="medicine">medicine</span> <span word="and">and</span> <span word="so">so</span> <span word="on">on</span>. <span word="The">The</span> <span word="ancient">ancient</span> <span word="Greeks">Greeks</span> <span word="regarded">regarded</span> <span word="the">the</span> <span word="moon">moon</span> <span word="as">as</span> <span word="Artemis">Artemis</span>, <span word="the">the</span> <span word="beautiful">beautiful</span> <span word="hunting">hunting</span> <span word="goddess">goddess</span>, <span word="and">and</span> <span word="regarded">regarded</span> <span word="the">the</span> <span word="silver">silver</span> <span word="bow">bow</span> <span word="that">that</span> <span word="the">the</span> <span word="goddess">goddess</span> <span word="never">never</span> <span word="left">left</span> <span word="when">when</span> <span word="hunting">hunting</span> <span word="as">as</span> <span word="the">the</span> <span word="astronomical">astronomical</span> <span word="symbol">symbol</span> <span word="of">of</span> <span word="the">the</span> <span word="moon">moon</span>.</p><p>月球基本上没有水，也就没有地球上的风化、氧化和水的腐蚀过程，也没有声音的传播，到处是一片寂静的世界。</p><p><span word="Basically">Basically</span>, <span word="there">there</span> <span word="is">is</span> <span word="no">no</span> <span word="water">water</span> <span word="on">on</span> <span word="the">the</span> <span word="moon">moon</span>, <span word="so">so</span> <span word="there">there</span> <span word="is">is</span> <span word="no">no</span> <span word="weathering">weathering</span>, <span word="oxidation">oxidation</span> <span word="and">and</span> <span word="water">water</span> <span word="corrosion">corrosion</span> <span word="process">process</span> <span word="on">on</span> <span word="the">the</span> <span word="earth">earth</span>, <span word="and">and</span> <span word="there">there</span> <span word="is">is</span> <span word="no">no</span> <span word="sound">sound</span> <span word="transmission">transmission</span>. <span word="There">There</span> <span word="is">is</span> <span word="a">a</span> <span word="silent">silent</span> <span word="world">world</span> <span word="everywhere">everywhere</span>.</p><p>月球上几乎没有大气，因而月球上的昼夜温差很大。白天，在阳光垂直照射的地方，温度高达127℃；夜晚温度可低到-183℃。由于没有大气的阻隔，使得月面上日光强度比地球上约强1／3左右；紫外线强度也比地球表面强得多。由于月球大气少，因此在月面上会见到许多奇特的现象，如月球上的天空呈暗黑色，太阳光照射是笔直的，日光照到的地方很明亮；照不到的地方就很暗。因此才会看到的月亮表面有明有暗。由于没有空气散射光线，在月球上星星看起来也不再闪烁了。</p>
