黄沙满天,大雾蒙蒙,一股黄风卷起……你们也许以为你在看电影,也许以为这在做梦,总而言之,你们相信这是真的吗?其实,这是沙尘暴“捣的鬼”。沙尘暴是沙暴大哥和尘暴小弟的总称,他们经常用风把地面大量沙尘卷入空中使空气十分浑浊。他们的出生原因是因人们大度砍伐树木与植物而产生的。沙尘暴兄弟俩作为一种高强度风沙灾害,并不是有风的地方他们都喜欢,只有植物稀疏的地方,他俩才去那里。如果那里是植物和树极缺的地区,他们就会亮出自己的绝招——瞬时风速每秒达25米,风力10级以上,可能使地面水平能见度低于50米!
沙尘暴是一种危害性极大的灾害性天气。当沙暴大哥和尘暴小弟找到自己的“作案地点”时,会以排山倒海之势滚滚向前移动。他们的“作案”后造成的后果可不小,有时,会使大片农田受到沙埋或被刮走活跃土,或者农作物受霜冻之害。它还能加剧土地沙漠化,给人民生命财产造成严重的损失,他们一旦出现,所经地区受害尤为严重。
去年12月31日和今年元月1日,沙尘暴兄弟肆虐甘肃省河西走廊,兰州市出现浮尘,在他们的统治下,连白天开车都要开车灯呢。今年3月底以前,甘肃河西走廊和内蒙西部已出现沙尘天气9次之多。3月中旬,兄弟俩的踪影出现在距沙漠地区遥远的南京市,引起人们的恐慌。
沙尘暴兄弟气焰嚣张,甚至飘扬过海,登陆日本了,日本的电视新闻都在说:从中国来的6年来最大的一次沙尘暴袭击了日本的大部分地区。
沙尘暴兄弟对人类的危害这么大,不除不足以平民愤呀!我想发明一种机器,专门治理沙尘暴。当然,我的机器它并不是《西游记》中多闻天王的混元珠伞,能把花果山的猴子收拾得干干净净,而是一种能播撒绿色的机器。因为沙尘暴兄弟光靠挡是挡不住的,只有把他们消灭在“出生”的地方,才是治本的好办法。沙漠是沙尘暴兄弟的“出生地”,我发明的机器,能把他们困在沙漠里不能出来“作恶”。机器的形状象一个超级可乐瓶,里面装满了富于营养的物质和植物的种子,这种瓶子可以固定在飞机的肚子下面,飞到沙漠上空的时候,就通过操纵杆打开“瓶盖”,把营养物质和植物种子均匀地喷洒在沙漠表面,营养物质里面饱含植物生长所需的水分,经过科学家的特别配制,落到沙漠上后并不会马上被沙子吸收或蒸发掉,它会一直坚持到植物长大为止。我相信,过了不久沙漠上就会遍布绿色植物了。我的机器表面涂着漂亮的绿色,好像在暗暗地告诉着我们要保护环境。有了我发明的机器,沙尘暴兄弟这两个祸害人民的“罪犯”肯定被绳之以法了,哈哈!
当然,这只是我的幻想,现在真正地实现这个愿望还要等一段时间。所以,我们要从身边的一点一滴做起,从身边的小事做起,努力学习科学文化知识,将来有更多的发明创造,让大自然变得更加美丽!
How to prevent the H7N9?
As is well known,the A flu is spreading throught our country. However, if we negnect it, the deadly H7N9 may cause more infectors,or even more deaths. So what is the most important is that we should take some effective measures to prevent it.They can be listed as follows.

今天的风特别的大,飞沙走石,天昏地暗,天气预报说有沙尘暴。 我去学校的时候衣服很干净,等回来时,衣服都挂有一层土了。街上的行人特别少,风刮的人都睁不开眼睛,举步艰难,顶风骑车的就像蜗牛一样,慢吞吞的。
下面是沙尘暴预防措施 :
1.加强环境的保护,把环境的保护提到法制的高度来
2.恢复植被,加强防止风沙尘暴的生物防护体系。实行依法保护和恢复林草植被,防止土地沙化进一步扩大,尽可能减少沙尘源地。
根据不同地区因地制宜制定防灾、抗灾、救灾规划,积极推广各种减灾技术,并建设一批示范工程,以点带面逐步推广,进一步完善区域综合防御体系。
5.控制人口增长,减轻人为因素对土地的压力,保护好环境。
在雷雨季节里,常会出现强烈的光和声,这就是人们常见的雷电。带有电荷的雷云与地面的突起物接近时,它们之间就发生激烈的`放电。由于雷云电压高电量多,并且放电时间很短,放电电流大,因而雷击电能很大。虽然放电作用时间短,但对建筑群中高耸的建筑物及尖形物、空旷区内的建筑以及特别潮湿的建筑物、屋顶内金属结构的建筑物及露天放置的金属设备等有很大威胁,可能引起倒塌、起火等危险事故。
俗话说:水火无情,地震无情。只要我们把安全牢记在心。那我们的生活就会变得多姿多彩。
