        沙塵暴

        關(guān)鍵詞:沙塵沙塵暴過(guò)度

        At first glance, dust storms do not seem very fascinating. Winds pick up fine particles from the ground, and then the air becomes thick with dust. What is interesting, though, is that dust storms can travel across the ocean, sometimes from continent to continent. Such dust storms are worth investigating.

        乍看之下,沙塵暴似乎不怎么引人注意。地面的細(xì)沙被風(fēng)卷起,空氣中便充滿(mǎn)厚厚的灰塵。但有趣的是,沙塵暴能穿洋渡海,有時(shí)還能橫越大洲。這樣的沙塵暴值得我們?nèi)ズ煤醚芯恳幌隆?/p>

        In April 2012, a dust storm that originated in China and Mongolia took a six-day journey across more than ten thousand kilometers of sea and open land to Arizona in the United States. The cloud was so dense that it seemed as if the sun were setting early. At least one person thought a volcano had erupted.

        2012年4月,源自中國(guó)及蒙古內(nèi)陸的沙塵暴,在六天中跨越了一萬(wàn)多千米的海洋與空曠陸地,最后到達(dá)美國(guó)亞利桑那州。陰云密布,就像太陽(yáng)將提早下山,不少人以為是火山爆發(fā)了。

        Although traveling dust storms are nothing new, the dust now often contains chemical or metallic substances that contribute to respiratory illnesses and damage the environment. At present, a group of researchers in Asia is studying aerosol particles and their effects on the environment—and they have plenty of dust to work with.

        雖然移動(dòng)的沙塵暴沒(méi)什么稀奇,但現(xiàn)在的沙塵暴中往往含有化學(xué)或金屬物質(zhì),這些物質(zhì)會(huì)導(dǎo)致呼吸系統(tǒng)疾病和破壞環(huán)境。目前,亞洲有一批研究人員正在研究大氣懸浮顆粒及其對(duì)環(huán)境的影響。他們要研究的沙塵可多著呢。

        Dust storms are one of the repercussions of humans messing around with Mother Nature. Although they are a natural phenomenon, dust storms have been occurring more often, at shorter intervals, and with greater force in recent years, and human activity is the cause.

        沙塵暴就是人類(lèi)肆意破壞大自然所造成的后果之一。沙塵暴雖是自然現(xiàn)象,但是近年來(lái)發(fā)生的頻率卻逐漸增加,間隔的時(shí)間也愈來(lái)愈短,威力更是越來(lái)越大,人類(lèi)的活動(dòng)是罪魁禍?zhǔn)住?/p>

        It is a fact that excessive herding of animals and exploitation of grasslands are responsible for the majority of dust storms. This means that dust storms are largely a result of human actions; in other words, they are controllable.

        事實(shí)上,沙塵暴形成的主要原因是過(guò)度放牧及濫墾草原,這表明沙塵暴大多是人類(lèi)活動(dòng)所致。也就是說(shuō),它們是可加以控制的。

        We seem to think, however, that economic development and preservation of the environment cannot go hand in hand. For most countries, economic development comes first, at the expense of the environment. It is high time everyone came to grips with the consequences of overusing the earths resources, including the misuse of land in the pursuit of economic wealth.

        不過(guò),我們似乎認(rèn)為經(jīng)濟(jì)發(fā)展與環(huán)境保護(hù)無(wú)法同時(shí)兼顧。對(duì)大部分國(guó)家來(lái)說(shuō),經(jīng)濟(jì)發(fā)展是第一位的,為此可以不惜以犧牲環(huán)境為代價(jià)。然而,我們已過(guò)度使用了地球的資源,包括為了追求經(jīng)濟(jì)繁榮而濫用土地,如今應(yīng)該是我們著手處理這個(gè)難題的時(shí)候了。
