ある塾の英語の長文テストなんですけど、問一の答えが順番に、3.2.4と書いてるんですが全く納得いきません。Part1が4でなく、3なのはまあ百歩譲れますが、Part3が4になる意味が分かりません。風力発電の環境面での利点なんて一文字も書いてない気がします 問題の作成ミスでし... Read More

You are preparing for a speech about alternative energy forms. You have found a journal article about wind energy. You are going to read the article and take notes. Wind Energy [Part 1] Scientists are always looking for more sustainable and cost-effective forms of energy, and many people believe wind energy is the best option available. Wind is a product of heat from the sun, so the energy supply will never run out. Wind does not pollute the air, water, or ground as it produces energy. Another major benefit of wind energy is that it requires no water. In contrast, traditional forms of energy production all require water for cooling. Due to its efficiency, scientists have worked to increase the capacity of wind production units. They hope to develop wind energy into a large-scale alternative to fossil fuels. [Part 2] Wind energy can be produced using offshore wind or land-based wind. The primary benefit of offshore wind collection is that it is more efficient because offshore wind blows more consistently and with more power than land-based wind. To take advantage of the steadier wind, offshore wind production units are bigger and have more capacity. Therefore, the energy acquired from offshore wind can produce significantly more electricity than land-based wind energy. Wind production units located in the sea off the coasts of big cities can efficiently provide energy to many people, while land-based wind production units take up valuable land space and require complicated transportation efforts. However, since it is a newer technology, offshore wind energy is currently more expensive than land-based wind energy. [Part 3] Even though it actually has ancient roots, producing energy from wind is usually thought of as a modern alternative to burning fossil fuels. Initially, wind energy provided power for electricity. But during the mid-20th century, it was replaced by fossil fuel resources. Unfortunately, the pollution created from the burning of fossil fuels is a major cause of global warming. This has forced scientists to develop more sustainable and cost-effective forms of wind energy. Currently, most offshore wind resources are located in coastal waters which are too deep for current wind energy technology. However, engineers are working to develop floating production units that can withstand the hard environment of the ocean, such as storm waves, hurricane-force winds, and ice flows. These developments offer wind as an effective source of energy without damaging the environment. Complete the notes by filling in 1 to Outline: Part 1: 8 Notes
