       "Go for it!"

       The expression "Go for it!" is a way of encouraging someone to try something.

       "Go for it!" means you should not worry about failure or be too careful. You should take a chance

and be brave.

       "Go for it!" gets its name from football. But it is not the football played in most countries such as

England, France or Japan, but the kind of football played in the United States and Canada.

       One of the most exciting times in football comes when a team has failed, after three tries, to move

the ball forward ten yards. The team must make a very important decision.

       The conservative(保守的)choice is to kick the ball and accept temporary defeat (暂时失败)in

order to get a good position for your team the next time it gets the ball. The more exciting choice,

however, is to try a fourth and final time to get the remaining yards needed.

       People now are certain to shout their advice.  Some will shout,  "Kick the ball!"  But others will

encourage the team to take a chance. "Go for it!" they will shout loudly.

       In the 1980's, people began using this expression in many kinds of situations(情形) to encourage

someone to act bravely.

       There is no guarantee(保证) that the action you "Go for it!" will succeed. But when you decide to

go for it, you only consider your action. That is the chance you can take. You put your fears behind.

You choose courage over safety. You hold your breath and go for it.

人类总是依据自身的利益评价外部事物,将之分成优劣好坏,而大自然则另有一套行为规范与准则。现在人们闻之色变的沙尘暴,即由于强烈的风将大量沙尘卷起,造成空气混浊能见度小于千米的风沙天气现象,其实古已有之。它本是雕塑大地外貌的自然力之一,是大自然的一项工程,并且在全球生态平衡中占有一席之地。
在地质史上,风力对草原带的风化物质进行筛选分类:凡搬不动的粗大砾石,留在原地形成砾石戈壁滩:颗粒适中的粗砂和细砂被吹移到附近就地聚集成沙漠;颗粒微小的粉沙细土和微尘,则被强上升气流扬上天空,作中长距离的输送。我国黄土高原的黄土层就是沙尘经数百万年堆积而成的,华夏文明就是在这块沙尘累积的黄土地上诞生和发展起来的。澳大利亚的沙尘乘着南半球的西风掠过塔斯曼海,使新西兰火山岛上的土壤更为肥沃,因而被称作“澳大利亚出口的珍贵产品”。从非洲内陆吹向地中海的强风帮助古罗马人使用帆船从埃及运回小麦,但也将撒哈拉大沙漠的沙尘带到意大利、西班牙和法国。沙尘暴固然使空气中的可吸入颗粒物增加,然而由于沙尘含有碱性,又可中和大气中的酸性物质,减缓酸雨的发生。
风是地球上空的传送带,它将大陆的沙尘吹向海洋,又将海洋的水汽吹向大陆。沙尘和水汽相遇,便能结合为云,最终化作降水。可见,沙尘不仅在土壤的分布和补充上扮演着重要角色,而且在全球的水循环上也扮演着重要角色。可以说,沙尘也是决定全球生态平衡的因子。
然而,近百年来,沙尘暴却已成为影响人类生产生活的一大灾害。构成我国沙尘暴的物质材料,多来自干旱、半干旱的草原区。在人为活动的干预下,特别是由于森林大量砍伐,土地过度开垦,工厂盲目建设,排放不加控制,结果造成生态巨变:原来有沙漠的地方沙漠扩大了;没有沙漠的地方沙漠产生了;内陆河流程缩短,水量减少,沼泽地消失;河流两岸的绿色走廊枯萎死亡。这样,来自大西北的沙尘暴,一路上还源源获得裸地上新的沙尘源的补充,而且混入了工矿企业排放的有害成分和来自草原上牲畜粪便中的病菌病毒。总之,在受到人为因素的干扰后,自然界的风蚀速度已远远大于土壤的生成速度,一连串的灾害也就由此产生。歌德说过:“大自然是不会犯错误的,错误永远是人犯下的。”这或许能给我们某种启示。

下列对沙尘暴的解释,最准确的一项是______。

A.沙尘暴是由于风将大量沙尘卷起,使空气混浊,能见度小于千米的风沙天气现象

B.沙尘暴是雕塑大地外貌的自然力之一,是大自然保持全球生态平衡的一项工程

C.从地质史上看,沙尘暴是风力对草原带的风化物质进行筛选分类的结果

D.沙尘暴是那些颗粒适中的粗砂和细砂被大风吹移到附近就地聚集成沙漠形成的
