有必要进行空间探索吗?(Do We Need Space Exploration)
<p> 有必要进行空间探索吗</p><p> 人类对外部空间着迷已有上千年的历史了。从人类第一次登上月球起至今已有40多年了。现在，有些人认为空间探索完全是浪费时间和金钱。他们指出，数百亿美元用于太空研究，但收获甚微。另外，用于研究的时间和金钱实在难以估计。</p><p> 然而，任何事物都具有两面性。仍有大多数人认为进行空间探索利大于弊，我也非常赞同他们的观点。许多新产品，如气象、通讯卫星都直接得益于空间研究，使全球受益匪浅，而且人 类从中获得了不少关于太空的知识。</p><p> 空间探索早巳使人类受益匪浅了，而且我们也相信，将来它会带给人类更多的好处，有些甚至是我们现在无法想像的。太空探索对我们人类来说是个挑战，这也是为什么许多国家不断进行探索的原因之一。</p><p> <span word="do">do</span> <span word="we">we</span> <span word="need">need</span> <span word="space">space</span> <span word="exploration">exploration</span></p><p> <span word="man">man</span> <span word="has">has</span> <span word="been">been</span> <span word="fascinated">fascinated</span> <span word="by">by</span> <span word="outer">outer</span> <span word="space">space</span> <span word="for">for</span> <span word="thousands">thousands</span> <span word="of">of</span> <span word="years">years</span>, <span word="it">it</span> <span word="has">has</span> <span word="been">been</span> <span word="almost">almost</span> <span word="over">over</span> <span word="forty">forty</span> <span word="years">years</span> <span word="since">since</span> <span word="man">man</span> <span word="s">s</span> <span word="first">first</span> <span word="landing">landing</span> <span word="on">on</span> <span word="the">the</span> <span word="moon">moon</span>. <span word="now">now</span>, <span word="some">some</span> <span word="people">people</span> <span word="believe">believe</span> <span word="that">that</span> <span word="space">space</span> <span word="exploration">exploration</span> <span word="is">is</span> <span word="a">a</span> <span word="sheer">sheer</span> <span word="waste">waste</span> <span word="of">of</span> <span word="time">time</span> <span word="and">and</span> <span word="money">money</span>. <span word="they">they</span> <span word="point">point</span> <span word="out">out</span> <span word="the">the</span> <span word="thct">thct</span> <span word="that">that</span> <span word="it">it</span> <span word="cost">cost</span> <span word="billions">billions</span> <span word="of">of</span> <span word="dollars">dollars</span> <span word="to">to</span> <span word="can">can</span>3 <span word="on">on</span> <span word="the">the</span> <span word="space">space</span> <span word="research">research</span>, <span word="but">but</span> <span word="a">a</span> <span word="little">little</span> <span word="infrmation">infrmation</span> <span word="was">was</span> <span word="brought">brought</span> <span word="back">back</span>. <span word="in">in</span> <span word="addition">addition</span>, <span word="the">the</span> <span word="time">time</span> <span word="and">and</span> <span word="money">money</span> <span word="spent">spent</span> <span word="on">on</span> <span word="space">space</span> <span word="exploration">exploration</span> <span word="is">is</span> <span word="too">too</span> <span word="much">much</span> <span word="to">to</span> <span word="calculate">calculate</span>.</p>
