防止沙尘暴
<p>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！</p><p><span word="The">The</span> <span word="sand">sand</span> <span word="is">is</span> <span word="all">all</span> <span word="over">over</span> <span word="the">the</span> <span word="sky">sky</span>, <span word="the">the</span> <span word="fog">fog</span> <span word="is">is</span> <span word="foggy">foggy</span>, <span word="and">and</span> <span word="a">a</span> <span word="yellow">yellow</span> <span word="wind">wind</span> <span word="is">is</span> <span word="blowing">blowing</span> <span word="You">You</span> <span word="may">may</span> <span word="think">think</span> <span word="you">you</span>'<span word="re">re</span> <span word="watching">watching</span> <span word="a">a</span> <span word="movie">movie</span>, <span word="you">you</span> <span word="may">may</span> <span word="think">think</span> <span word="it">it</span>'<span word="s">s</span> <span word="dreaming">dreaming</span>. <span word="In">In</span> <span word="a">a</span> <span word="word">word</span>, <span word="do">do</span> <span word="you">you</span> <span word="believe">believe</span> <span word="it">it</span>'<span word="s">s</span> <span word="true">true</span>?
