为粗略测定一个滑动变阻器的最大电阻R，小明按图正确连成电路，其中电源电压大于6V，电压表仅有0~3V量程可用，灯泡L的额定电压是3V，电阻是R₀（阻值不变）。

实验步骤：

（1）使滑片P处于阻值最大的位置，闭合开关S，电压表示数为U₁；

（2）调节滑动变阻器的滑片P至中间位置，电压表示数为U₂，此时滑动变阻器连入电路中的电阻为R’。由导体电阻与_______的关系可知R’=0.5R，则R=___________（用相应字母表示）。假如滑动变阻器的阻值太大，电压表示数会_____，导致误差太大，这种情况下，只需要再增加_____________（限一种器材），仍可粗略测定滑动变阻器的最大电阻R。

下图是转基因鼠的研制过程，请据图回答问题：

（1）在这项实验中，被研究的性状是鼠的     ，控制这个性状的基因是        。

（2）转基因超级鼠的获得，说明性状与基因之间的关系是：                     。

（3）由此推断，在生物传种接代的过程中，传下去的是    （填“性状”或“基因”）。

（4）在这项实验中，出生的超级鼠的变异     （填“会”或“不会”）遗传给后代。

（5）以上研究过程主要利用了现代生物技术中的           技术。

There’s a story in Texas about the rancher who complained when a well driller found oil instead of the water he had been sent to look for. "Cattle can’t drink that stuff!" the rancher cried.
That story is no longer funny. We are short of both oil and water, but the water shortage is worse. (1) And we are using water a great deal faster than it is being replaced. The replacement rate is dependent on rainfall (sometimes in the form of snow) to resupply rivers, lakes, and ground water. (2) Worse, droughts are occurring more frequently and are increasing in severity, not only in the United States but also abroad.
Even without droughts, rainfall is insufficient to maintain a balance. (3) So much water has been taken from the Colorado River by Arizona and California that Mexico has complained that those states have exceeded the U.S. share under a 1944 treaty on water-sharing. Southern Californians also have elaborated arrangements to transport water from the Pacific North west, which has it in abundance, to their area, which doesn’t have nearly enough to support its population. (4)
Short of a fanciful solution, the U.S. has two broad options, neither pleasant. We can conserve or we can produce. The former is inconvenient or worse: less irrigation (and thus less food), fewer swimming pools golf courses, and green lawns. (5) In the quantities necessary, this would probably require nuclear power. It is technically feasible, but expensive, and was considered 30 years ago as a joint U.S.-Mexican project in the Gulf of California to alleviate the Colorado river problem. As more of it is done, the cost could be expected to come down; and as we became more desperate for water, we would be more willing to pay the cost even if it didn’t come down. (6) This is an arrangement whereby large landowners would sell the groundwater under their land, for whatever the market would bear, to cities that might be hundreds of miles distant. This would involve the considerable cost of pipeline construction and would mean faster depletion of groundwater reserves. (7)
It’s a good bet that during the 21st century some new arrangements are going to have to be made about the nation’s — and the world’s — water supplies. These are likely to be neither cheap nor easy. They are more likely to be cheaper and easier if we have thought about them in advance. (8) We have been sued to choices of guns or butter. This one might be water or meat.

• A. A century ago, a drought affected only farmers and perhaps inland navigation; now it affects everybody.
• B. The Northwest is showing signs of getting tired of this drain.
• C. It is not too soon to begin.
• D. We cannot live without oil in the style to which we have become accustomed, but we cannot live at all without water.
• E. Rivers are running dry, especially in the West.
• F. It would also mean less food production.
• G. A solution currently being advanced in west Texas is a concept called "Water Ranching".
• H. The latter is expensive: desalinization of seawater.
