① The development of wind energy, solar energy and tidal energy can effectively alleviate the energy supply dilemma in China, among which wind power generation is the first one with the most mature industrialization conditions. Compared with other new energy sources, wind power generation has more obvious advantages: large reserves, exceeding all the reserves of oil, natural gas and coal; Theoretically, only 1% wind energy can meet the energy demand of human beings.

On the coast of Jiangsu, from Nantong to Lianyungang, there are hundreds of kilometers of beaches. This is a new continent with wealth and dreams but hidden by nature. The annual wind speed here is maintained at 7-8 meters per second, which is an excellent wind farm.

(3) Offshore wind farms can be built in this area with more than 6.5438+million kilowatts, which is equivalent to the installed capacity of the Three Gorges. It can be called "Three Gorges on the Sea", but it does not bear the burden of millions of immigrants, nor does it occupy cultivated land or consume water resources. 1 With the investment of the Three Gorges, 2-3 wind farms of the Three Gorges scale can be built. Moreover, wind power is a clean natural resource, and there is no pollution caused by a large amount of carbon dioxide emitted by thermal power generation.

Although the prospect is so attractive, wind energy can not be generated by setting up windmills. Because there are two world-wide "obstacles": First, the large-scale integration of wind power into the conventional power grid is due to the large fluctuation of voltage and frequency in thermal power, which will endanger the conventional power grid; Second, the structure of wind turbines is complex, and the price of wind power is much higher than that of coal-fired power. The unit power cost of wind power equipment in China is more than twice that of coal-fired power, so it is difficult for power grid companies to accept or simply refuse to buy wind power. Some people compare wind power to "garbage electricity".

⑤ After 10 years of research, some experts found that the value of wind power is no less than that of gold for some industrial production, especially for high energy-consuming industries such as nonferrous metallurgy and chlor-alkali. It not only reduces or completely eliminates the harm to the power grid, but also reduces the production cost and greatly improves the production efficiency. Through non-grid-connected technology, wind power can quickly enter specific industries with high energy consumption, and "garbage electricity" can be turned into "gold electricity". In the production of electrolytic aluminum, the power consumption per ton of aluminum is amazing10.5 million kwh. If wind power is specially supplied to large aluminum plants, huge electric energy will be "replaced", and wind energy will also gain a way to benefit the society. This is a revolutionary technology with strong challenges. If successful, China will lead the world in wind power generation technology.

⑥ At present, the non-grid-connected technology has been basically overcome, and the next step is to find a pilot project in Jiangsu Province. Once the pilot is successful, it will be the latest milestone in the utilization of wind energy in the world.

7. After reading the whole article, please draw up a suitable title for this article. (2 points)

8. In paragraph (2), why do you say, "This is a new continent with wealth and dreams, but it is hidden by nature? (4 points)

9. Combined with the context, talk about the expression effect of words in the following sentences. (4 points)

(1) Wind power can quickly enter specific energy-consuming industries through off-grid technology, and "garbage electricity" can be turned into "gold electricity".

(2) Once the test is successful, it will be the latest milestone of wind energy utilization in the world.

10. Why should we vigorously develop the wind power industry? Please state it item by item. (4 points)

7. Wind energy will make Jiangsu coastal areas become "Three Gorges on the Sea" (or "The prospect of wind energy utilization in Jiangsu coastal areas is attractive").

8. Because there are huge wind resources here, once used, it will have great economic and social value, but due to the limitation of technical conditions, it has not been fully utilized.

9.( 1) "Golden Power" vividly shows that the non-grid-connected technology will bring huge benefits to wind power generation, and by analogy, it will become as valuable as gold.

(2) "Once" indicates the uncertainty of time, indicating that non-grid-connected technology is still in the pilot stage and may become a reality in the future. It reflects the accuracy of explanatory language.

10, ① Compared with the development of other new energy sources, the industrialization conditions of wind energy are the most mature; (2) Compared with oil, natural gas and coal, wind energy reserves are large; Compared with hydropower, the investment is less, the development does not bear the burden of millions of immigrants, nor does it occupy cultivated land and consume water resources; (4) Compared with thermal power, there is no pollution caused by a large amount of carbon dioxide emission.
