Water in the Desert的第8题 原文:Most limestone and sandstone aquifers are deep and extensive but may contain ground waters that are not being recharged. Most shallow aquifers in sand and gravel deposits produce lower yields, but they can be rapidly recharged. 正确答案:Groundwater in deep aquifers is more likely to be recharged than groundwater in shallow aquifers 这根原文不是相反么?我看了半天没看明白。 求解答。谢谢谢~~
