On a clear night, the moon shines brightly overhead. You might think that the moon gives off light,
but it does not. Light from the sun reflects off the moons surface. Sometimes the moon looks like a large ball steady in the sky. Other times it looks like a tiny sliver. Myths, or legends, were made up by early people to explain why the moon changes shape. The early people of Greenland thought the sun goddess was chasing her brother, the moon god, across the sky. Greenland is an island in North America. The moon god ran so much that he forgot to eat, so as days passed, he became thinner. Finally, the moon god had to stop and eat. He got bigger, and the chase began all over again. Today people understand why the shape of the moon changes. The changes in the shape of the moon are caused by the way the moon moves in space. The moon moves in two ways. It rotates, or spins around like a top. It takes the moon about twenty-nine days to rotate once. It also travels in a path around the earth called an orbit. The different shapes of the moon are called phases. This is what the phases of the moon look like:
full
waxing gibbous
half moon
waning
waxing
The phases of the moon in orderare:
full,
waning gibbous,
half moon,
crescent,
new moon,
waxing crescent,
half moon,
waxing gibbous,
and full.
gibbous
crescent
half moon
new
crescent
The moon takes about twenty-nine days to orbit around the earth. The sun always lights up half of the moon. We do not always see the lit-up half from the earth. When you see all the lit-up half of the moon, the moon appears to be a full circle. This is called the full moon. As the moon travels around the earth, we see less and less of the lit part. This is called the waning moon. Soon the lit-up part of the moon disappears from sight. This is called the new moon. Then the moon starts to look lit up again, and the lit part that you see gets bigger each day. This is called the waxing moon. It takes about twenty-nine days for all the phases. Thats the same amount of time it takes for the moon to make one
trip around the earth. Starting in the 1950s, spacecraft were sent to study the moon. The spacecraft orbited the moon. In this way, scientists learned more and more about the moon. Then, on July 20, 1969, the first spacecraft carrying astronauts from the earth actually landed on the moon! People were able to watch as a person walked on the moons surface for the first time ever.It was on television!
The astronauts sent the pictures of the moon back to the earth. The astronauts brought moon rocks back to the earth. From the rocks, scientists have learned a lot about the moon. The rocks were evidence that scientists could study to find out how the moon might have been formed. Scientists think the moon might once have been part of the earth. They think a large object from space hit the earth millions of years ago. The dust and ashes from the earth went into space and formed the moon. People have learned a lot aboutthe moon since early times!
俄顷风定云墨色,秋天漠漠向昏黑。秋,它代表着丰收,代表着热情,还代表着丰收的喜悦。
秋,丰收的开始,生命的尽头。它并非代表着生命的尽头,却依然拥有着热情与美。田野间,道路边,秋随处可见,而并不茫茫,四周都有树,平地是金色的,树也是金色的。金黄的小手掌一会儿飘在空中,一会儿又落在了平地上,无论落在哪里,都像给平地绣上了几朵金黄色的花朵,使我总想高歌一曲,表示我满心的愉快。
秋,一幅美丽的画卷,夕阳夕下,飒飒秋风,芦花飞扬,瓜果飘香,明月高悬。 秋,那朵朵小花,飘在空中,像一只只蝴蝶,落在小河里,仿佛是金色的小船。秋,那一把把小扇子,扇走了夏天的炎热,扇走了蝉鸣的歌声,扇走了绿色的毛毯。
八月秋高风怒号,卷我屋上三重芧。秋高气爽之时,偶尔狂风袭卷大地,白亮亮的雨珠跳入屋内。
金桂飘香,花好月圆。在中秋这个美好的节日里,无论是赏月、吃月饼,都寄托着人们无限的思念。海上升明月,天涯共此时。中秋那轮明月,会将我们的思念传递给我们所牵挂的人。正如苏轼所言:明月几时有?把洒问青天。
春风桃李花开日,秋雨梧桐叶落时。我爱你秋,我爱你的瓜果飘香,我爱你的秋风落叶,我爱你的绚丽多彩,我爱你

生 日
怀念我的老院
天津一考生
十五岁的生日到了。
妈妈在新装修的房子里,显眼地摆放了两盆鲜花,一盆是火红火红的三角梅,一盆是开得像一团绣球的杜鹃。金利来的蛋糕,一只可爱的小绵羊属性玩具早早就等在一旁。表姐的短信,小舅的祝福已提前将生日晚宴做了预演。
但我的惆怅和寂寞却充满胸膛。望着窗外一排排的新楼房,听着楼道里传来那陌生的脚步声,我怀念起生活了十四年的老院,那时过生日,从来没有过这般孤单的感觉。
老院,我整整度过了十四年,今天又这样顽固清晰地浮现在眼前
老院的清晨,用不着拧紧闹钟的发条,拖鞋的踢踏声,放水的哗哗声,梦中被父母推醒的孩子不情愿的哈欠声,都是唤你起床的时钟。
互道一声早安,老院开始了新的一天。骑自行车的、开摩托车的、乘公交的、匆匆小跑的一半人走出了老院。
送走了早间的喧闹,各家留守的老人又开始了张罗。收拾屋子、准备午饭、交流着给孩子过生日的花样。张家奶奶说说家里的难处,李家爷爷发发退休的牢骚。倒班休息的二大爷还抓紧时间修起了那辆爱唱歌的的自行车。悠闲的气氛送走了漫长的白天。
老院永远没有寂寞。当放学的孩子如归巢小鸟般飞回来,当上班的大人们似归航的帆船靠了岸,当家家窗中射出祥和的灯光,你能闻见各式各样的饭菜飘香,你能听见各家妈妈愉悦的呼唤,老院最醉人的一刻来到了。
在老院里,你不用担心门被锁上,因为左邻有你的钥匙;你别害怕忘了给花浇水,因为右舍早就顺便给你想到;孩子放学了,家里来了不速之客,你都不用担心像一家人一样。满院弥散着患难相助,幸福分享的爱的空气。
尽管新楼房的环境是那么干净、漂亮。但我忘不了老院长满青苔的水池,忘不了剥落灰墙上的爬山虎,更忘不了全院人簇拥着我一口气吹灭蜡烛的生日晚宴是老院陪伴我度过了那么多令人怀念的岁月!
今天的生日,昨天的老院
四月的雨,悄无声息地下着。
安静地听着雨声,看着它下落。它们唱着歌,飞舞着。它们溅起水花,跳动着。风中雨,雨中风,配合得天衣无缝。那纷飞的雨点,只求得迸溅后的粉身碎骨,只愿激起片片涟漪,滑落在窗上,滴在叶上,流进人们的心里。它如此坦然而又平和。
在这条两旁种满梧桐的小巷中,雨轻轻地飘落。它冲刷着青灰的石板路,洗涤着鲜绿的梧桐叶。一切都变得光亮。那躲起来的青苔,也像染了头发,绿得那么鲜艳。这幽静的小巷偶尔有撑伞走过的人,他们也总是慢慢地踱步,看这幅画,听这首诗。
一颗颗浮躁的心,渐渐平静
这样的小雨,我是不愿打伞的。总觉得这晶莹的雨滴,是神圣的使者,是圣洁的化身,会洗掉所有污秽。而我,也愿接受它的洗礼,任它飘落,打在头发上。
那些在雨中嬉戏的孩子们,不知是否也认为如此。那欢快的笑声和这清脆的雨声混合,融为一体
我想这飘舞的精灵,是雨的精魂。
它飞散在人间,化成苏生的希望,化成欲断魂的哀愁,化成绵绵无绝的诗。
它轻悄悄的,不惊扰任何人
我冲了杯茶,坐在窗台前看窗外淅淅沥沥的雨,心情释然。
这四月的雨,还在悄无声息地下着
