다 아실듯.. 토플 핵허쓰 롸이팅에.. 수소 개발... 뭐 리딩에서 수소 찬성 리스닝에서 수소 반대 하는것.... 첨삭 부탁합니다;;;;; 다음주가 시험이라 ㅜㅠ 또 해커스 책엔 라이팅 1번 문제 쓴거 보면 conclusion 이 없는데.. 안써도 되나요??? |
The lecturer downright disagrees with the the points made in the reading passage. He claims that hydrogen as the resource of tomorrow is not very realistic, as it is more expensive, not auspicious for the environment, and hard to store and transport. This is contrary to the reading passage's claim that hydrogen may be the perfect energy source people could use in the near future.
The lecturer argues that the cost of producing hydrogen would be unimaginably immense. The production of hydrogen, where water is seperated into oxygen and hydrogen, requires substantial amount of electricity. This, he says, will be very expensive, thus increasing the price of hydrogen fuel. This clearly refutes the proposition made by the passage that hydrogen would be a much cheaper energy.
Also, the lecturer says that the making of hydrogen is not protective of the environment, either. As massive amount of electricity is used, by-product is made. The process of making hydrogen itself pollutes the environment. Wind and sunlight that could be used for the production of hydrogen are environmentally friendly, but not always available. Thus, according to the lecturer, the passage is not true about hydrogen being favorable to the environment.
Lastly, the lecturer argues that the storing and transporting of hydrogen is very difficult. According to the lecture, hydrogen is highly dangerous as it could cause an explosion. The storing and transporting of hydrogen is thus very perilous. The hydrogen storage alloy, the lecturer says, is too heavy. If the metal were used in automobiles, the weight of the alloy would even exceed the weight of the car itself. Thus, he refutes the statement in the passage that the storing and transporting of hydrogen is easy. |
