Renewable resources of energy will soon replace the old resources of fossil fuels.
楼主,帮忙看下啊,这是我第4篇托福作文。我现在写到第四篇作文,还是要写好久,最少要写一个多小时才能写完,而且这篇我改了差不多四个小时。我就在那改啊改,总是想表达但是表达不出来,就一直在想,居然改了四个小时!我太崩溃了啊……5555……楼主,我该咋办啊?这篇文章我抓狂了……急需帮助与建议哈!谢谢啊……
Living in the age of machines, it’s hard to imagine what will happen without energy. Not only does energy enable trains run on the railway, airplanes fly in the sky, but also keeps us warm in the winter and drives away the darkness at night. As we know, nowadays, a vast amount of energy is supplied by fossil fuels .Notwithstanding, fossil fuels’ negative effects has became increasing serious so that scientist has to develop renewable energy , like wind, water and sun, to deal with this problem. A question has been raised: Will cars soon be running on solar power instead of gas? The way I see it, renewable energy will replace fossil fuels eventually but not very soon.
Fossil fuels have brought us so much hazards that they must be out in the future. Firstly, Fossil fuels have caused many disasters. For example, the burning of fossil fuels release a vast amount of carbon dioxide into atmosphere, which aggravates Green House Effects and leads to global warming. No one can stay calm when they see The Day After Tomorrow, the disaster film which depicts a world where global warming triggers an abrupt climate change, creating a super storm that causes unimaginable worldwide weather disasters. In a span of just a few days, Tornados devastate Los Angeles, huge hail ponds Tokyo, blizzards whip New York. We must remember, such disasters will actually happen if we continue to ignore global warming. Besides global warming, Acid rains, deforestation, sea level rise are all the results of the burning of fossil fuels.
Secondly, fossil fuels are far more expensive than the renewable energy. We all know, fossil fuels take millions of years to form and reserves are being depleted faster than new ones being formed. The more they are use, the less they remain. Their limited shortage gives rise to the sharp increase of fossil fuels price. For example, the crude oil price has soared from fifty dollars per barrel in 2005 to one hundred and twenty dollars per barrel in 2008. Therefore it’s for us to develop renewable energy and lower the price of fossil fuels.
Fossil fuels, due to their drawbacks and negative consequences, will be replaced by renewable energy in a long term , as we have discussed above. Nevertheless, to say that renewable energy will replace fossil fuels very soon seems to be an overstatement.
Clean and eco-friendly though renewable energy is, it still has some disadvantages. For one thing, the use of renewable energy such as wind power and hydropower relies on particular geographic and climatic conditions. For another thing, the application of renewable energy requires tremendous investments. For example, it costs China billion Yuan to build the famous Three Gorges Dam.
In short, it’s a certain thing that renewable energy will replace fossil fuels, but this shift will not happen overnight. As long as the world believes firmly and acts bravely, the shift will be realized. |
