托福听力美国科学60秒精选

　　托福听力美国科学60秒精选!在听力的复习过程中，同学们需要寻找一些听力材料，来训练我们的英语听力。新东方在线托福网为大家推荐的是美国科学60秒，并且附带了相关的译文和重点句型。

　　原文：

　　This is Scientific American — 60-Second Science. I'm Christopher Intagliata.

　　As Houston begins recovery efforts from Hurricane Harvey, a new storm threat—Hurricane Irma—is barreling west towards the Caribbean and Florida. We have few defenses against hurricanes' lashing rains and wind and storm surge—but nature does provide one.

　　"Wetlands act in two ways to reduce the impacts of storms. They reduce storm surge by acting as a wall or a barrier and they act as a sponge by soaking up the waters that come down via rainfall."

　　Michael Beck is a coastal scientist at The Nature Conservancy and the University of California Santa Cruz. He says as we've paved over swampy coastlines, we've changed how storm waters flow. Or, for an analogy a little closer to home:

　　"Rain falls on your driveway, it's going to run straight out into the street. Rain falls in your garden it's going to soak into the ground. When you've done that at the scale of whole watersheds, there's no place for that water to go when it rains."

　　But some wetlands do remain. Beck and his colleagues teamed up with the insurance industry, and, using the industry's risk assessment models, asked: how much more damage would Hurricane Sandy have delivered if all the eastern seaboard's wetlands were gone? And they found that marshy coastlines saved some $625 million dollars in direct flood damages—or about one percent of Sandy's total cost.

　　The researchers also battered Ocean County, New Jersey, with thousands of hypothetical storms using flood models. And they found that wetlands cut flood damages there by 16 percent, compared to areas of the county where wetlands are gone. The study is in the journal Scientific Reports.

　　Next, it's up to local governments and the insurance industry to take notice. "Certainly we hope that we will continue to conserve wetlands in part for their intrinsic beauty and the importance of nature." But he says by putting a price-tag on the economic benefit of wetlands it might change the conversation ... about conservation.

　　Thanks for listening for Scientific American — 60-Second Science Science. I'm Christopher Intagliata.

　　译文

　　这里是科学美国人——60秒科学。我是克里斯托弗·因塔利亚塔。

　　当休斯顿刚开始从飓风“哈维”造成的破坏中恢复时，另一场风暴威胁——飓风“艾玛”正在迅速向西移动，逼近加勒比海和佛罗里达州。对于飓风带来的狂风暴雨和风暴潮，我们几乎无法抵抗，但是大自然为我们提供了一道防护。

　　“湿地有两种降低风暴影响的方法。其中一种是像墙或屏障那样抵御风暴潮，另一种是像海绵那样吸收雨水。”

　　迈克尔·贝克是大自然保护协会和加州圣克鲁斯大学的海岸科学家。他表示，我们在遍布湿地的海岸线铺路时，改变了暴雨积水的流向。或者打个更贴近生活的比方：

　　“落到你家私车道上的雨水会直接流到街上。而落在你家花园里的雨水会渗透到地下。因此，如果整个流域都被改变，那下雨时雨水就无处可以去了。”
