1.  Groundwater is stored in the pore spaces and joints of rocks andunconsolidated (unsolidified) sediments or in the openings widened throughfractures and weathering. the water saturated rock or sediment is known as an"aquifer". Because they are porous, sedimentary rocks,such assandstones and conglomerates, are important potential sources of groundwater. largequantities of water may also be stored in limestones when joints and crackshave been enlarged to form cavities. Most limestone and sandstone aquifers aredeep and extensive but may contain groundwaters that are not being recharged.most shallow aquifers in sand and gravel deposits produce lower yields,butthey can be rapidly recharged.Some deep aquifers are known as "fossil"waters .The term "fossil" describes water that has been presentfor several thousand years .These aquifers become saturated more than10,000years ago and are no longer being recharged.
   9.According to paragraph 6, the aquifers called “fossil”waters
A. contain fossils that are thousands ofyears old.
B. took more that 10,000 years to becomesaturated with water
C. have not gained or lost any water forthousands of years
D. have been collecting water for the past10,000 years
感觉C(答案）中的lost看不太出来啊，文章只说了不会recharge，并没有说不会流失之类的。

顶下啊~

很明显答案应该在这句话里面：The term "fossil" describes water that has been present for several thousand years .These aquifers become saturated more than10,000years ago and are no longer being recharged.
楼主觉得除了C还有合适的吗？D？最后一句话说的是10000年之前就已经是saturated了，之后再没有被recharged。

还有，从10000之前就saturated，之后没有recharge，现在仍然saturated，这意思应该很明显吧？

4# Santon 这个现在还saturated怎么看出来的。。
