11月14日的独立写作重复了2015年5月24日考题。典型的政府投资类题目，需分析该投资的好处。虽然是一个同意与否题型，但题目中给出了两个比较项，即practical things和beautiful things，写作中应该注意加以对比论证。另外，在写作前应思考，两个选项分别指代哪些事物，即找出该选项的下义词，比如beautiful things包括公园，花园，艺术博物馆等；practical things包括地铁，公路等。
Should the government spare a thought for things of aesthetic value when allocating financial resources? My answer is surely in the affirmative on grounds of people’s well-being and social development.
First and foremost, beautiful things soothe people’s nerves. Living in an age when competitions are taking place in all areas and at all levels, most people are exposed to a fast-paced life: children are chained to the desks in the confrontation of mounting course loads, and working adults are occupied with furthering their careers on personal time while making family the extension of their workplace. That hectic schedule is not only introducing people to growing stresses, but also, unfortunately, encroaching upon people’s private time to the detriment of their intimate relationships. It then follows that many ordinary individuals, on one hand, are struggling with pent-up feelings right while on the other hand blocking the very vent they need without realizing it. In this case, places pleasing to the eyes may provide a desirable remedy. To be specific, gardens with melodious songs of birds and fascinating views of flowers lure people into taking a walk and having a cozy chat with families; sweat-inducing climbing in a park with lively friends surely lets off steam; also, likes and comments show up on social media about pictures taken against some exotic-looking art museums or libraries help reconnect those long-lost friends, with whom people exchange news. Needless to say, spots of aesthetic value afford ideal sites for social events, thus the necessary outlets for people’s emotion and energy. In this sense, expenditure on beautifying the society is truly rewarding. By contrast, things serving practical purposes like base stations and free Wi-Fi service hardly promote people’s mood, which, in some cases, even aggravate their mental burden with information overload.
On top of that, preserving places of interests facilitates social advancement. Few would deny that historic buildings or ancient sculptures as precious cultural heritage passed down from previous generations never fail to fascinate viewers. After all, we always gravitate to our shared bond to the past, seeing it as an interesting window into the path leading all the way to our present. Thus how we’ll reap the benefits from safeguarding the historic sites will not be hard to imagine: well-maintained historical monuments and stuff like that hold constant appeal, luring visitors from all over the country even all over the globe. Coincident with the flood of travelers comes the rise in consumption, which is, in other words, burgeoning demands in things like food, souvenirs and accommodation. Then more stores or industries like restaurants, hotels, shops and travel agencies will emerge in response, with more positions created and more people hired. Hence, a ripple effect like this is believed to boost the economy to a great degree. In this way, an argument can be made that preserving unpractical while enchanting things like historic buildings is worth every penny, considering all the financial returns it’ll bring. In stark contrast, practical things like subways or hospitals, while significantly easing people’s lives, can hardly bring economic benefits as such.
From what is discussed above, the conclusion can be safely drawn that apart from practical concerns, things of aesthetic value also deserve the authority’s attention in deciding where the budget goes.
