【题目】 California has been facing a drought(干旱) for many years now, with certain areas even having to pump freshwater hundreds of miles to their distribution system. Luckily, new research has found deep water reserves under the state which could help solve their drought crisis. Previous drilling of wells could only reach depths of 1,000 feet, but due to new pumping practices, water deeper than this can now be extracted( ). The team at Stanford investigated the aquifers(地下蓄水层) below this depth and found that reserves may be three times what was previously thought.

The aquifers range from 1,000 to 3,000 feet below the ground, which means that pumping will be expensive and there are other concerns. The biggest concern of pumping out water from this deep is the gradual settling down of the land surface. As the water is pumped out, the vacant space left is compacted(压实) by the weight of the earth above.

Even though pumping from these depths is expensive, it is still cheaper than desalinating (脱盐) the ocean water in this coastal state. Some desalination factories exist where possible, but they are costly to run and can need constant repairs. Wells are much more reliable sources of freshwater, and California is hoping that these deep wells may be the answer to their severe water shortage.

One problem with these sources is that the deep water also has a higher level of salt than shallower aquifers. This means that some wells may even need to undergo desalination after extraction, thus increasing the cost. The result of a thorough study of groundwater from over 950 drilling logs has just been published. New estimates of the water reserves in the state now go up to 2,700 billion cubic meters of freshwater.

1How could California’s drought problem be solved according to some researchers?

A.By building more reserves of groundwater.

B.By drawing water from the depths of the earth.

C.By developing more advanced drilling machines.

D.By improving its water distribution system.

2What is mentioned as a consequence of pumping water from deep underground?

A.The sinking of land surface.B.The harm to the ecosystem.

C.The damage to aquifers.D.The change of the climate.

3What does the author say about deep wells?

A.They run without any need for repairs.B.They are the final solution to droughts.

C.They are entirely free from pollution.D.They provide a steady supply of freshwater.
