【News report one】

A NASA satellite orbiting over Portugal took photographs that reveal the effects of pollution from ships. One of the photos shows a thin film of clouds above the brilliant blue of the north Atlantic, cut by white lines of thicker clouds that look like scars. (1) NASA officials explained those thicker clouds are signs of ship traffic below when ships power their way through the ocean, they pump exhaust into the atmosphere. Just as cars do.

And those massive amounts of particles can cause clouds to form, get enough of those particles in one place as from the exhaust of a ship. And they can lead to the creation of new clouds easily visible from space. These clouds can be huge. Some of them stretch hundreds of kilometers from end to end. (2) NASA officials said it's likely that these sorts of clouds are having some effect on the global climate, according to NASA officials.

Question 2 What do NASA officials think about the thick clouds?

三、听力答案：

葡萄牙上空运行的一颗美航天局(NASA)卫星拍摄的照片揭示了船舶污染的影响。其中一张照片显示，蔚蓝的北大西洋上空笼罩了一层薄云，间或还有更厚的云朵像疤痕一样穿插其间。轮船开动油门在海上行驶，也会向大气中排放废气，与汽车一样。排出的巨量微粒便会形成云朵。当足够多的尾气微粒，就比如足够多的轮船尾气微粒积聚在一个地方，就会形成从太空都能轻松看见的云朵。“有的非常大，从一端到另一端的宽度足有数百千米，”NASA官员表示。据NASA官员称，这些类型的云可能已经对全球气候产生一定影响。但具体是何种影响科学家们尚不确定。

请根据刚才所听的新闻报道回答1-2题。

问题1：是何原因导致了出现在美国航天局(NASA)卫星照片中的厚厚云朵？

问题2：航天局官员对厚厚的云朵有何看法？
