　　2.Directions:

　　61. Read the following text and write an essay to

　　1) summarize the main points of the text,

　　2) make clear your own viewpoint, and

　　3) justify your stand.

　　In your essay, make full use of the information provided in the text. If you use more than three consecutive words from the text, use quotation marks (“ ”).

　　You should write 160-200 words on the ANSWER SHEET.

　　Sunlight is free. Turning it into electricity produces no greenhouse gases and the process is getting cheaper every year. These facts suggest solar power ought soon to be a big part of the world's energy mix. However, it is unavailable at night and is most efficiently generated in deserts. Can these problems be overcome? Or is solar power forever destined to be financially aided greenwash that is applied superficially to fossil-fuel-based economies to make them seem more environ. mentally friendly than they really are?

　　This motion depends on whether the world needs saving, and if so, from what?

　　There are two conventional answers to the second question. One is, "from the effects of climate change brought about by man-made global warming". The other is, "from dependence on fossil fuels that are, by definition, a finite resource".

　　Both of these answers are challengeable. Few informed people doubt that humanity's outpourings of greenhouse gases, particularly carbon dioxide, are altering the climate. But there is doubt over both how big that, effect will be and whether the response should be to try to stop the change or to adapt to it. The former would certainly require an approach to alternative energy, in which solar power would play an important--and probably eventually dominant--role. The latter would argue for business as usual, with access to the cheapest energy sources (ie, at the moment, fossil fuels) to help bring about the economic growth that will help pay for adaptation to an altered climate.
