California has been facing droughts for many years, with certain areas even having to pump freshwater hundreds of miles to their distribution system. The problem is growing as the population of the state continues to expand. 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 (抽取). 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.
It is profitable to drill to depths more than 1,000 feet for oil and gas, but only recently in California has it become profitable to pump water from this depth. 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 is the gradual setting down of the land surface. As the water is pumped out, the vacant space left is pressed 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 the largely coastal state. Some desalination plants 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 water may even need to be desalinated after extraction, thus increasing the cost. Research from the study of groundwater has just been published. New estimates of the water reserves now go up to 2,700 billion cubic meters of freshwater.
1.According to the text, what causes the water crisis in California?
A.Previous drilling of wells. B.The messy distribution system.
C.Constant droughts in the area. D.The adoption of new pumping practices.
2.The research teams think it ________ to extract water from deeper aquifers.

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(抽 取). 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.
1.How 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.
2.What 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.
3.What 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.

In recent years many countries have been faced with the problem of how to make their workers more productive. Some experts believe that the answer is to make jobs more varied. Do more varied jobs lead to greater productivity? There is something to suggest that while variety certainly makes the worker's life more enjoyable, it does not make him work harder. So variety is not important.
Other experts feel that giving the worker freedom to do his job in his own way is important and there is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated machinery which must be used in a fixed way. Thus while freedom of choice may be important, there is very little that can be done to achieve this.
Another important consideration is how much each worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are said to be experimenting with having many small production lines rather than a large one, so that each worker contributes more to the production of the cars on his line. It would seem then that the degree of worker contribution is important.
To what extent does more money lead to greater productivity? The workers themselves certainly think this is important, but perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if companies succeed in making workers' jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.
72. Which of the following things will not increase productivity?
A. Making jobs more varied.
B. Longer working hours.
C. Giving workers the freedom to do his jobs in their own way.
D. Increasing the workers' contribution to production.
73. The last sentence in this passage means that if companies manage to make workers' jobs more interesting, _________.
A. they will want more money
B. they will demand shorter working hours
C. more money and shorter working hours are important
D. more money and shorter working hours will not be so important to them
74. In this passage, the writer tells us _________.
A. how to make the workers more productive
B. possible factors leading to greater productivity
C. more money leads to greater productivity
D. how to make workers' jobs more interesting
75. The writer of this passage is probably a _____________.
A. teacher B. worker C. manager D. physics

Your Car Is Ready for Take-off
The flying car has been talked about for many years,but now it appears that the idea is about to become a reality.
An international company has built a two-seater plane that, at the touch of a button ,transforms into a car perfectly suitable for driving on public roads. It has been designed so that the wings fold up automatically; and it takes just 15 seconds to switch between flying and driving. With its wings fully open and the propeller(螺旋桨)spinning, it can take off from any airfield.
Flying cars are quicker than traditional ones for travelling from city to city,and they can run on ordinary fuel. Another big advantage is that they are cool ,like something you would see in an action film. At the moment 9 however, the flying car’s wheels are illegal to leave the ground. That is not because of technical reasons or problems with the design. It is because the various road and aircraft authorities simply cannot agree on whether it is a car or a plane.
“The government and the authorities have never thought seriously about a flying car, says Alan Price ,the president of the company that has developed it. “I wanted a car that could fly and drive ,but it is difficult to find an organization prepared to insure the vehicle against accidents.
Nevertheless ? the company hopes to produce and deliver its first flying car soon. The company already has orders for 40 of them. The majority the potential customers are older and some are retired。There have even been orders from some people who have no pilot's license.
The flying car will cost around $ 200.000. “For an airplane , that’s a very reasonable price, but for a car, It's quite expensive,” explains Alan. “But it just is not possible to make a $ 10,000 flying car yet. ”
This latest means of transport will not become a mass-market item in the near future,but in the long term it has the potential to change the way you travel. It will become no more expensive than driving your car on the motorway. Travel time could be reduced by more than half.
So the next time you are told to fasten your seat belt, it may be to prepare for take-off.
1.We know from the passage that the flying car______
A.has to run on special fuel B.will replace traditional planes
C.is popular with the rich D.can shift between two forms
2.The flying car is presently forbidden to take off because______.
A.many people think driving it not very safe
B.it’s hard to decide whether it's a car or a plane
C.the government and the authorities don’t accept it
D.there are still some technical problems to be solved
3.We can learn from the passage that______.
A.few people will be able to afford a flying car
B.flying cars may share the market in the future
C.traffic jams will disappear because of flying cars
D.driving a flying car doesn’t require a pilot’s license
