CNN News: 路易斯安那州500年不遇大洪水 數(shù)萬(wàn)人撤離已知11人喪生

Hi. I`m Carl Azuz. Just two days from the weekend, we`ve got a lot of interesting reports lined up for you today on CNN STUDENT NEWS.

大家好，我是卡爾·阿祖茲。還有兩天這周就結(jié)束了，今天的CNN新聞?dòng)泻芏嘤腥さ氖虑樾枰獔?bào)道。

One story we`ve been following this week is the historic flooding in the U.S. state of Louisiana. A by the numbers look helps us explain how bad it is, especially in Southern Louisiana.

這周我們追蹤的一則報(bào)道是關(guān)于美國(guó)路易斯安那州發(fā)生的歷史性的洪災(zāi)。數(shù)多景象能讓我們知道路易斯安那州南部的災(zāi)情是有多嚴(yán)重。

Six-point-nine trillion, that`s the number of gallons of rain that started all this, between August 8th and August 14th. Livingston Parish in particular got more than 31 inches of rain in just one day.

在8月8號(hào)到8月14日，共降雨6.9億萬(wàn)加侖。特別是利文斯頓僅一天降雨就達(dá)31英寸。

Forty thousand, that`s the number of homes that had been damaged, in what Louisiana governor calls a major disaster. Twenty thousand, the number of people who`ve been rescued so far. Eleven deaths have been blamed on the floods across the state.

其中約與4.5萬(wàn)所房屋被毀，路易斯安那州州長(zhǎng)表示，這是重大災(zāi)難。目前為止，共有2萬(wàn)人被救。11人死亡。

Five hundred years, the likelihood that a flood this catastrophic would occur in the Baton Rouge. It means once every 500 years.

五百年前，巴吞魯日發(fā)生了類似災(zāi)難性的洪水事件，這意味著，此類事件每500年發(fā)生一次。

And finally, 12, the number of Louisiana parishes that had been declared federal disaster areas. That speeds up federal government assistance to them. More than 12 other parishes may also get this declaration.

最后，共有12個(gè)路易斯安那州的教區(qū)已經(jīng)成為聯(lián)邦災(zāi)區(qū)。聯(lián)邦政府加速救援?，F(xiàn)在教區(qū)災(zāi)區(qū)數(shù)量已經(jīng)超過(guò)12個(gè)。

We touched on the definition of flash floods the other day. Jennifer Gray now explores what makes this flood so dangerous.

我們提到了洪水的定義。氣象學(xué)家格雷現(xiàn)在像我們解釋此次洪水的危險(xiǎn)性。

In the U.S., flash floods kill more people than tornadoes, hurricanes or lighting. A flash flood creates a rush of moving water than can sweep a grown man off his feet, a car off the road and even your entire home off its foundation.

在美國(guó)，與龍卷風(fēng)、閃電相比，死于洪水的人的數(shù)量更多。突如其來(lái)的洪水可以沖走成年男子、汽車、甚至將房屋也連根沖走。

When the ground becomes so saturated that water can no longer seep in to the soil, it begins to run off quickly into rivers and streams and this causes a rise in water and a flash.

當(dāng)?shù)孛骘柡秃?，水不能再滲入地表，因此洪水迅速流入河流和小溪，導(dǎo)致水位上漲，最終導(dǎo)致洪水。

Densely populated areas have an extremely high risk of flash flooding with additional concrete than less grassy areas for the water to soak into the soil. And they can see flash flooding very quickly. In mountainous terrain, the combination of gravity, plus the easy runoff can lead to catastrophic flooding when all of that water is funneled into rivers, creeks and even the valleys.

人口密集區(qū)，由于混凝土多、而可吸收水的草坪少，因此洪水事件較多。同時(shí)，會(huì)迅速發(fā)生洪水事件。在山區(qū)，重力以及徑流會(huì)導(dǎo)所有的水注入河流,小溪,甚至山谷，從而引發(fā)災(zāi)難性的洪水事件。

Remember, flash flooding can happen in a blink of an eye. That`s why it`s important to stay alert and pay attention in case a flash flood watch or warning is issued for your area.

記住，突發(fā)洪水只是眨眼之間。這就是為什么需要保持警惕并注意檢測(cè)突發(fā)洪水以及警報(bào)。
