    A NASA satellite orbiting over Portugal took photographs that reveal the effects of pollution from ships. (1) [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. 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 amount 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, NASA officials said. (2) [It’s likely that these sorts of clouds are having some effect on the global climate, according to NASA officials.] But scientists aren’t yet sure what effect it has.

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

解析：C。根据选项关键词effect、affecting、causing等，推测题目可能涉及某事物的影响。根据录音最后一句可知，美国宇航局官员说这些云层很可能正对全球气候产生某些影响，但是科学家们还不确定具体有怎样的影响。C项内容是对此内容的同义替换，be affecting对应录音中的having some effect，world’s climate对应录音中的global climate，故正确答案为C。

错项排除：A项中的taken seriously和D项中的air flights在录音中均未提及，故排除。B项利用录音中的having some effect作干扰，原文虽然提到ships，但并没有提及fishery（渔业），B项属于过度推断，故错误。
