参考答案

正确答案:D
解析:"... this relatively small amount of water in the global water cycle [0.001% of the total water on Earth]... produces all our freshwater resources." Choice A is not correct because the residence time of 9 days is more than one week. Choice B is not correct because both glaciers and oceans are unsuitable for human use. Choice C is not correct because only a relatively small amount of water is in the global water cycle at any one time.
