今天期末考试，有这样一道题：月亮给太阳讲夜晚的梦想。它会说什么呢？
Todaysfinalexam,thereissuchaquestion:themoontellsthesunaboutthedreamofthenight.Whatdoesitsay?
深夜，月亮姐姐悄悄地说：“太阳公公，这儿好安静，人们都睡着了，看他们睡的多甜，这可是我的`功劳呀！”无人应答。
Inthemiddleofthenight,themoonsistersaidquietly,"Grandpasun,itssoquiethere.Peopleareasleep.Itsmycredittoseehowsweettheysleep!"Noresponse.
黎明的时候，月亮姐姐终于熬不住了，嚷嚷道：“太阳公公，快出来，该你站岗了！”说完，倒头就睡了。
Atdawn,themoonsisterfinallycouldntbearit.Sheshouted,"SunGong,comeoutquickly.Itstimeforyoutostandguard!"Afterthat,hefellasleep.
就这样，太阳和月亮轮流着每天值班。

每天早上你都能看到东方的太阳升起。太阳给我们光明。当你站在阳光下，你能感受到热量。太阳从很远的.地方给我们热量。太阳大约一亿五千万公里远。它看起来很小，因为它离我们那么远，但它实际上是非常大的。
地球绕着太阳转。绕着太阳走一年的地球。植物，动物和人需要太阳。没有太阳，我们就不能生存。
紧紧系在悬索上的大圆盘形太阳帆，已经鼓满了宇宙间的长风，像一名斗志昂扬、整装待发的勇士。三分钟内比赛就要开始了，约翰·默顿的心中却非常的轻松与平静。

“最后两分钟，”座舱无线电发出指令，“请检查准备情况。”船长们逐个回答。“1号——‘游丝’号，准备好出发！”“2号——‘圣玛利亚’号，一切准备就绪！”“3号——‘阳光’号，准备就绪！”“4号——‘投标器’号，一切系统正常！”“5号——‘列别捷夫’号，我们准备就绪！”“6号——‘蜘蛛’号，准备就绪！”默顿在出发线的末端，听着朋友和对手们的声音，现在轮到他回答了。“7号——‘狄安娜’号，准备好出发！”裁判员的声音非常平静，“现在，最后１分钟。”“……5、4、3、2、1，断缆！”

刀片割断了把飞船拴在为其进行总装和维护的母船上的细线。七艘帆船开始散开，宛如蒲公英的花籽在轻风中飘散。优胜者将是第一个飘过月球的人。座舱仪表表明“狄安娜”号正以千分之一的推动力增加着速度。这全是太阳风的力量！按这个速度，绕地球两圈之后，就能达到第二宇宙速度，那时它将向月球飞去。

默顿看到了他的对手们，他们犹如朵朵银花绽放在幽暗的宇宙空间。做了40多年的飞船设计师，他渴望独自驾着飞船，赢得成功。

刚睡了两个小时，警钟响亮而刺耳的声音就把他从无梦的酣睡中惊醒。默顿敏捷地检查了一下指示吊索拉力的仪表，在太阳帆一侧，读数正常--可是，在另一侧，拉力在慢慢下降。
Justaftersleepingfortwohours,theloudandharshsoundofthealarmclockwokehimupfromthedreamlesssleep.Mertonquicklycheckedthegaugeindicatingtheslingpull.Ononesideofthesail,thereadingwasnormal-butontheotherside,thepullwasslowlyfalling.
光线在渐渐消失，“狄安娜”号静悄悄地滑进地球的阴影里，太阳垂直落在不可见的地平线之下，夜幕降临了。飞船已经走过四分之一的`轨道，进入短暂的夜晚，一小时后太阳才能从巨大的黑影中浮现出来，在这一小时中，飞船将做无动力滑行。

现在只剩下“狄安娜”号、“列别捷夫”号和“投标器”号了，但“投标器”号为了追赶前两艘太阳帆船，把悬索减修到最小重量，但当它再次从几千公里高的出发线上经过时，太阳射线的额外能量把悬索压断了，帆船像一块手帕在太空中飘动着。

“狄安娜”号和“列别捷夫”号展开了直接对抗，“狄安娜”号暂时领先。
"Diana"and"Lebedev"launchedadirectconfrontation,"Diana"temporarilyahead.
默顿毫不感到疲倦，他只有两种担心：第一是担心8号悬索，它已不能调整了，只能用其他悬索尽力做最佳航行；第二是担心“列别捷夫”号，它正在300公里之后尾随着他。俄国人的飞船有可围绕中心帆而倾斜跷起的四块巨大翼板，显示出极大的灵活性。

然而，在比赛的第五十个小时，接近地球第二圈末尾时，“列别捷夫”号使默顿略吃一惊，帆桁和悬索与中心方形帆分离开，飘然进入宇宙空间。“列别捷夫”号放弃了一切不必要的东西，这样，它很快达到了第二宇宙速度。默顿在像火柴盒那么大的计算机上算出，“列别捷夫”号将正好在他期待的通过月球的时刻赶上他。

官方救险发射装置上的指挥官范·斯特拉注视着从高悬在太阳炽热表面的太阳观察站上发回的照片，他的双眼，充满了失望，比赛将不得不放弃。默顿为自己和“列别捷夫”号遗憾，他们都应该赢得比赛，而今胜利却不属于任何人。太阳处于愤怒中，没有人能争胜负了。

默顿切断了悬索，银色的太阳帆飞走了，他搭上了救险的太空飞艇。他的心情慢慢平静下来，他永远不能赢得飞往月球的比赛了，但他的帆船却将是飞行在星际的漫长航程上的第一艘人造太阳帆船。
