Balloon flying high, and finally flew to the sky, the children are in the sky holiday, the children sit on clouds, umpa jump, like a frisky little monkey.

Children's good play my imagination, to one day be able to live in such a children's day.
随着时光的流逝,我那既天真又有趣的童年也悄悄地走开了。然而充满童趣的一幕幕已在我记忆的脑海里定格着。
记得那是我6岁的时候,我看见妈妈买回来一大袋的香瓜子。当妈妈放下袋子的时候,我便像离弦的箭一样跑到袋子的前面,把袋子撕地七零八落,取出了一包香瓜子。当我吃着香喷喷的瓜子时,不禁问妈妈:“妈妈,这些这么香的瓜子从哪儿得到的呢?”妈妈耐心地对我说:“这些瓜子是由向日葵那里得来的,只要种下一颗花籽,就能种出许多美味的香瓜子。”我听着听着就流下了口水,脑海中并想出了一个计划。
我把一包香瓜子全种在地里,浇了许多桶水。可是一个星期过去了,也还没看见香瓜子长出来。我急得像热锅上的蚂蚁。于是,我就把香瓜子全挖了出来。挖出来一看,香瓜子不但没有长出鲜嫩的小花苗,反而上面还有许多小蚯蚓。我就把这件奇怪的事告诉了全家人,家人们笑得前仰后翻,我不知道怎么回事,就带着疑惑的心情问妈妈:“妈妈,大家为什么要笑啊?”妈妈笑着说:“儿子,你拿煮熟的香瓜子去种,当然种不出向日葵,只有生的香瓜子才能种出向日葵,不信你就试一试。”在妈妈的帮助下,我种的向日葵终于长出了小花苗。
这件事,虽然已经过去了很久,但是这件童年趣事像天边的一颗璀璨的星星,永远留在我心中的星空上。
从胎儿后期开始,人就有睡眠,出生后更是如此,如果按每人每夜平均睡8小时计算,那么一位70岁老人一生中花在睡眠上的时间竟达20万个小时之多,人的生命是可贵的,也是有限的,花这么多时间在一项单一的、周而复始的、又不太了解内容的活动上,值得不值得?相信每个人都会有这样的疑问。
可是,对睡眠的研究虽然经历了很长的时间仍然不能说已经彻底搞清楚了,20世纪50年代以来,由于多导睡眠仪的发明和应用,人们对睡眠的认识已经深入了许多,从初步的实验结果来分析,科学家发现,睡眠是每个人在生命中都必须满足的一种绝对需要,就像食物和水一样。根据观察,健康人能忍受饥饿长达三星期之久,但只要缺觉三昼夜,人就会变得坐立不安、情绪波动、记忆力减退、判断能力下降,甚至出现一些错觉和幻觉,以致难以坚持日常生活中的活动。
然而,尽管睡眠对每个人是如此的重要,但不同的人对睡眠的需要并不相同,一般说来,女性比男性所需要的睡眠时间略多一些,有些人每夜只睡3~4小时就清醒、精神饱满,但另一些人则每夜必需睡10~12小时才能解乏,否则白天会头昏脑胀、无精打采、工作难以为继,历史上有些名人以睡得少而著称,如拿破仑每夜最多睡4小时,但也有以好睡闻名的,所以就睡眠时间长短而言,每个人的要求都不会一样。
所以,专家提醒:失眠的病人最好是自己和自己不失眠的时候比较,而不要和别人比较,目前对健康的成年人来讲,每夜平均睡7~9小时就已经足够了,睡眠对每个人来讲,都是绝对必需的、不可或缺的生活需要,因此,如果感觉长期的睡眠不足、睡眠质量不好就要尽早治疗,以免对身体的健康产生影响。
Elephants are the biggest wild animals in land, in the world. But now, they are also in danger. Let me tell something to you about them.
Elephants are big and strong and they are grey. They have long trunks and tusks, so they look a little dangerous. But in fact, they’re friendly towards each other and hardly hunt people.
Elephants have ears like fans, they make them look bigger and bigger.
They live in a group together for many years, they’re a big family. They also have good hearing and good sense of smell. Elephants can do lots of things if people train them. For example, they can carry heavy things, can do as a vehicle, ext.
Badly, it’s difficult for elephants to survive in the world usually because of people. If people sell tusks, they will make lots of money.
So, many people kill elephants for their tusks. Living areas are also an important reason of the die out of elephants.
Animals are our friends, we should protect them, or the number of wild animals will getting smaller and smaller.
Elephants are the biggest animals on the land.They are big and srong.They have big ears and trunks.They can walk quietly and help people move heavy things. They are very friendly,kind and always live together.But the number of elephants reduces.People kill elephants for their ivories.We must take action to protect them or else they will extinct from the world.
