有一篇文章中的两道题不是很明白：
Electricity from Wind

Paragraph 3: Wind power has a significant cost advantage over nuclear power and has become competitive with coal-fired power plants in many places. With new technological advances and mass production, projected cost declines should make wind power one of the world’s cheapest ways to produce electricity. In the long run, electricity from large wind farms in remote areas might be used to make hydrogen gas from water during periods when there is less than peak demand for electricity. The hydrogen gas could then be fed into a storage system and used to generate electricity when additional or backup power is needed.

Paragraph 4: Wind power is most economical in areas with steady winds. In areas where the wind dies down, backup electricity from a utility company or from an energy storage system becomes necessary. Backup power could also be provided by linking wind farms with a solar cell, with conventional or pumped-storage hydropower, or with efficient natural-gas-burning turbines. Some drawbacks to wind farms include visual pollution and noise, although these can be overcome by improving their design and locating them in isolated areas.

3. Based on the information in paragraph 3 and paragraph 4, what can be inferred 　　about the states of North Dakota, South Dakota, and Texas mentioned at the end of paragraph 1?
○They rely largely on coal-fired power plants.
○They contain remote areas where the winds rarely die down.
○Over 1 percent of the electricity in these states is produced by wind farms.
○Wind farms in these states are being expanded to meet the power needs of the United
States.
第四个选项不知道错在哪个地方，还有就是第二选项是不是可以翻译成这些地区包括了风源不足的偏远地区？


Paragraph 1: Since 1980, the use of wind to produce electricity has been growing rapidly.
█In 1994 there were nearly 20,000 wind turbines worldwide, most grouped in clusters called
wind farms that collectively produced 3,000 megawatts of electricity. █Most were in
Denmark (which got 3 percent of its electricity from wind turbines) and California (where
17,000 machines produced 1 percent of the state’s electricity, enough to meet the residential
needs of a city as large as San Francisco). █In principle, all the power needs of the United
States could be provided by exploiting the wind potential of just three states—North Dakota,
South Dakota, and Texas. █
13. Look at the four squares █that indicate where the following sentence could be added
to the passage.
Some companies in the power industry are aware of this wider possibility
and are planning sizable wind-farm projects in states other than California.
Where would the sentence best fit?
Click on a square █to add the sentence to the passage.

为什么是放在最后一个空呢？我选择的是第三选项。不太明白。
