这么大的事,当然也逃不过我那机智的耳朵。当我听说到这件事后,连忙跑回家,兴致勃勃地通报家人。我等啊等,终于等到了7月22日。那天我从抽屉里拿出了“四大宝贝”——照相机、胶片、日全食眼镜和一盆水。
上午9时左右,盼望已久的日全食终于开始了。一开始,天空雾茫茫的.一片,什么也看不见,估计是白云姐姐爱臭美,就把太阳公公遮在了一边,满不在乎。过了一会儿,太阳公公终于懊恼了,“砰”的一击,把白云姐姐撞了个伤口,号啕大哭起来。这事被月亮婆婆看见了,她狠狠地踢了个太阳公公四脚朝天,并且遮住了他。他誓死不降,把月亮婆婆推啊推,自己露出了鸡蛋大小的脸。又过了一会儿,他已经露出了四分之一,月亮婆婆快坚持不住了。这时,天突然黑了,原来太阳挤出了环形“贝利珠”样子,像一串闪闪发亮、金光灿灿的项链,样子十分美丽!不过10分钟,月亮婆婆就已经筋疲力尽,她想:我已经这么累了,而且毕竟自己能力有限,上了把年纪,干吗还要为白云报仇呢?何苦啊!终于,月亮放弃硬顶了,太阳顿时金光四射,普照大地,蓝天白云霞光四照。
人们通过观测了以上这个天文奇观,大家是不是都对日全食有了更深一步的了解和看法啦!

太阳表面分为三层,即光球层、色球层、日冕层。其中光球层的.温度大约6000K,但它的光最强,我们平时看到的太阳就是它的光球层,色球层的温度要高于光球层,可达几万度,但色球层的光很微弱,只有在日全食时才可以看到。最外层是日冕,温度更高,可达100万度,但它的光却弱到只有借助天文设备才能看到。此外,日冕层还会发生太阳风的现象,太阳风会抛射高速的粒子流,干扰地表通讯系统。除日冕外,干扰地表通讯系统的还有太阳黑子和太阳耀斑,它们的爆发周期都是11年。
在太阳内部的中心,有一个密度约为固体铅14倍,磁场强度约为1000-400高斯的日核,其温度约为1500万度,那里一直在发生核聚变,每四个氢原子聚变为一个氦原子,并向外散发出巨大能量,但太阳也要因此而每秒亏损约300万吨的质量。大约40亿年后,太阳中心的氢原子将消耗殆尽,此时太阳将开始消耗它的氦原子作为燃料并且其体积会迅速膨胀。再过大约10亿年左右,太阳中心的氦原子也消耗殆尽,此时太阳的内部将会发生坍缩,其密度会迅速增大到175千克/立方厘米,变成一颗白矮星,但太阳还会继续向外发光,直到太阳完全死亡。然后,它将停止发光,最终变为一颗黑矮星。

你们可要知道,我和你们有着密切的关系,我对你们的用处可大了。首先,我是地球上植物的生长﹑动物的生存,繁殖所必须的条件。要是没有我,地球上的'庄稼和树木就不能发芽﹑长叶﹑开花﹑结果。鸟﹑兽﹑鱼﹑虫就不能生存,自然也就没了人类;要是没了我,地球上将到处是黑暗,到处是寒冷。
因为有了我,才能给你们送来光明和闻暖,才能有你们这个美丽可爱的世界。地球是你们的母亲,也是我最值得骄傲的孩子,我希望你们保护好自己的母亲,否则,地球将回会灭亡,那我也将会对你们不可气。
二零三五年六月七日早八点零九分十秒,随着“十、九、八……三、二、一”的倒计时声,我的“长城一号”将以比光还快的速度登上月球。到了月球,我满以为吴刚会给我一杯桂花酒,嫦娥抱着玉兔陪吴刚一起来呢。可当我下了飞船,谁都不在,然后我就开始寻找他们踪迹,但终极一无所获。原来月亮上并没有蟾宫、玉兔、婵娟、吴刚,那只是人间的一个个神话故事。月亮上没有空气,白天温度高达127摄氏度,晚上骤降至零下183摄氏度,在这三项恶劣的条件,是不可能有人类或者外来生物存活下来。但月亮的.安静和纯洁深深吸引着我们人类,为了缓和地球拥挤的居住条件,全世界都在找寻月亮上适合人类生存的资源。我就是带着这样的使命登上了月球。我穿着粗笨的宇航服,在月球上行走,走了好久,辨不清东西南北,于是我拿出我们祖先伟大的发明——指南针来测定自己的位置,可指南针一动不动,原来月亮是没有磁场的。
这时,我的肚子不争气,饿得咕咕直叫,于是我拿出一袋食品充饥,可等我刚刚把包装纸撕开,里面的食品就满天飞舞,看到这情景,我便马上使出我的抢篮技术,来场食品夺取战,情况开始不妙了,我的手快要捉住食品时,它却又飞走了,最后我非但没有抢到一颗食品,差点连自己都飞上了天,成为了一只没有翅膀的麻雀。
我只得忍着饥饿继续找矿物,找着找着,我看见了山脉,高原,平原,低地和坑***,但我轻轻一跳便过往了,我感觉自己成为了电视里的蜘蛛侠,用自己吐出的丝飞过往一样,真开心啊!半天下来,我共找到了六十多种矿物,这里面还有五种地球上没有发现的矿物,我把矿物整理装带回地球研究。月亮安静祥和,没有地球的嘈杂和污染,我独安闲月亮上享受这“世外桃源”。
返回地球的时间到了,我真舍不得离开月亮,我一定会再回来的,月亮等着我。
