1、沙尘暴无情地袭来。整个天空黑沉沉的,一片灰暗。院子里,那一排排大柳树摇摆着它坚强的身躯,刚吐着嫩绿的枝条却折断了它脆弱的生命。
2、只见远处的蓝天突然出现了一片灰,在不断的向前延伸着、变大着、变宽着,像夜神的毛毯般挡住了阳光,遮住了苍穹。
3、天地之间混沌一片,尘土、废纸、塑料袋漫天飞舞。道路两旁的小树被风吹得东倒西歪,无力地挣扎着。路上的行人蒙着脸,低着头,逃难似的往家跑。
4、眼见风来沙旋移,经年不省草生时。
5、天昏地暗,飞沙走石,狂风怒吼,满天黄沙沙石狂舞在苍穹, 卡车深陷泥潭中; 刹间乌瘴漫天空, 笔直落入人间崩。
6、黄昏后天色大变,狂风开始肆虐,夕阳早早地躲在了西方,天地开始灰暗阴沉起来,伴随而来的就是刺鼻的粉尘味,弥漫在户外户内,让你无处可藏。
7、化尽素衣冬未老,石烟多似洛阳尘。
8、风伯伯毫不留情的刮着,像刀子似的,刮在我的脸上,生疼生疼的,而老天爷似乎没看见,还是刮着,天上黄黄的一片,天和地的界线并不是很清晰,浑然一体。
9、西面的天上,已灰蒙蒙一片压过来,一边灰黄,一边湛蓝,也算一景。灰挤过来,蓝退出去,一会,整个城市便被沙尘一口吞了。只有太阳在挣扎,一会被沙尘推走,一会又挤进来,在灰黄的天上,旋着一个忽强忽弱的亮点。
10、迷漫扬沙如窒死,(.)奈何自作岂能饶。
11、风“呼呼”地吹着大地,卷起了一层厚厚的'尘土;沙子、石子满天飞;有的树被刮得“沙沙”作响;空气里四处弥漫着一股呛人的黄沙。
12、好大的沙尘暴,真个是遮天蔽日!纷纷扬扬遍天涯,邓邓浑浑大地遮。细尘到处迷人目,粗灰满谷滚芝麻。
13、青海的沙尘暴,就不象甘肃的这样混沌。如果说,甘肃的是炖刀割肉,那青海就是快刀斩乱麻。青海那里的沙尘暴是阳光下的沙尘暴,一面阳光照耀,一面风沙起舞。风声是呜呜的,偶尔带一两声尖叫,飞起的砂砾打在车上,发出“当当”的声音。一阵疾风,真能把石头吹得满地乱滚,那也叫一奇观。
14、瞬间,还没来得及反应,黄沙便一扫而过,刚才的一切都象魔术一样消失了,眼前只是一片黄,看不到房子,看不到汽车,甚至看不到自己的腿。
15、沙漠,沙尘暴,这是上天给人类的活生生的警告。人类可以放弃生存规则折腾、放弃良知祸害他人、放弃家园迁徙,但如果大自然要选择了放弃,那会放弃什么呢?
16、沙尘暴铺天盖地地撕扯着黑暗中的一切。
17、远处黄龙腾起,声如牛吼,嗷嗷的,象闷雷滚动,天边,一开始有一条抖动的黄线,向前滚动,越来越宽,十分壮观。
18、还没到学校,就刮起了大风,刮得车一晃一晃的,沙土刮到脸上非常疼,方便袋在天上飞扬,天变得黄黄的,好像穿上了黄色的衣服。
In general, the sandstorm refers to carry large amounts of dust storm, tend to occur in the desert or semi-arid areas. But have strict scientific sense of the sandstorm. Weather in general with visibility to differentiate between the sand and dust storm: visibility less than 1 km to dust storms, visibility 1 km in more for dust or flying sand weather.
Experts with the China environmental testing station with the concentration of suspended particles in the air as a measure. Recently suspended particle concentration dust weather in Beijing general not more than 1000 micrograms per cubic metre, and dust concentration is far more than the index.
The expert points out, should distinguish between dust, flying sand and dust, etc. Three kinds of common weather conditions. Dust weather, diffuse tiny particles in the atmosphere, dust from outside, the flying sand weather of sand is local. Dust and flying sand dust weather with the two kinds of weather conditions, but the ratio of the two are changed. Dust weather as part of the index, can only be called a sandstorm.
一般而言,沙尘暴是指携带大量尘沙的风暴,多发生在沙漠或半干旱地区。但科学意义上的沙尘暴却有严格的指标。气象上一般以能见度来区分沙尘与沙尘暴:能见度小于1公里的为沙尘暴,能见度在1公里以上的为沙尘或扬沙天气。
中国环境检测总站的专家们则以空气中悬浮颗粒物的浓度作为衡量指标。最近北京沙尘天气时悬浮颗粒物浓度每立方米一般不超过1000微克,而沙尘暴时的浓度是要远远超过这个指标的`。
专家指出,应该区分浮尘、扬沙和沙尘等3种常见天气情况。浮尘天气时,大气中弥漫细小颗粒物,灰尘多由外地而来,扬沙天气卷起的沙土则完全是本地产生的。沙尘天气兼有浮尘和扬沙两种天气情况,不过二者所占的比重有变化。沙尘天气达到一定的指标,才可称作沙尘暴。
Good afternoon, ladies and gentlemen, Today I'm going to talk about sandstorm.
Sandstorm is a kind of bad weather witch is becoming increasingly common in Northwestern China, and it usually happens in spring and fall. Though I'm only 13, I have experienced it and suffered from it quite a lot.
I'm sure most people still remember the sandstorm that happened last month. It swept across the large area of 11 provinces and caused a great loss to our nation.
As you can see on TV, when a sandstorm comes, the wind blows strongly with dust and sand. Sometimes trees are even broken down in half, and little birds cannot find their homes. Sometimes clouds of dust blur the vision, and little kids cannot find their ways. It's like the end of the world.
When a sandstorm occurs, our classroom is filled with dust and sand. My poor teachers! They've breathed in enough chalk-powder. Now, they have to take in much dust. My poor fellow classmates! They told me they were almost dying.
We love beautiful spring. We cherish bright sunshine. But sandstorms destroy all the lovely things. Yet we know it is Mother Nature's revenge on what we have done to her. In order to see blue sky and sunny spring again, we should plant more trees and more grass to protect the environment. And it is not too late if we start right now.
Though it's a hard job to fight against the sandstorm, it is the battle we must fight, and it is a battle we must win!
Thank you!
女士们,先生们:
下午好!我的演讲题目是沙尘暴。
沙尘暴是我国北方地区春季日益频繁发生的一种恶劣天气。虽然我才13岁,但也经历过多次了。
我想大家对上月发生的沙尘暴记忆犹新,它席卷了11个省,给我国造成了很大的损失。
正如您从电视上看到的,沙尘暴所到之处,狂风卷着黄沙和尘土肆劣横行,有时候一些大树都被从中间吹倒了。鸟儿失去他们的家园,孩子们也找不到回家的路,就像到了世界末日。
当沙尘暴发生时,我们的教室也充满了沙尘。可怜的老师,尽管已饱受粉笔灰之苦,现在又不得不待在灰尘中。可怜的.同学们,他们告诉我简直都要窒息了!
我们热爱美丽的春天,我们珍爱明媚的阳光。但是沙尘暴给这些蒙上了阴影,我们知道,沙尘暴是大自然母亲对我们破坏生态劣行的惩罚。要重新看到蔚蓝的天空和明媚的春光,我们必须绿化山川,保护环境。如果我们现在就开始,还不晚。
虽然这是一项艰巨的任务,但是我们必须勇敢地面对,因为这是一场我们必须获胜的战斗!
