TEXT A The English language exists in a condition of everlasting danger, its American branch most particularly, assaulted as it is from all sides by those who would reduce it to puzzling and obscure jargon, pop-psychological nonsense and vague beautified words, but it is not without its defenders. Ken Smith, author of Junk English, is the leading figure. He begins with a brief and clear declaration: "Junk English is much more than loose and casual grammar. It is a signal of human weaknesses and cultural license: abandoning the language of the educated yet giving birth to its own self-glorifying words and phrases, favoring appearance over substance, broadness over precision, and loudness above all. It is sometimes innocent, sometimes lazy, sometimes well intended, but most often it is a trick we play on ourselves to make the unremarkable seem important. Its scope has been widened by politicians, business executives, and the PR and advertising industries in their employ, who use it to spread fog before facts they would rather keep hidden. The result is... a world of humbug in which the more we read and hear, the less we know." Smith is, of course, saying something not true—it is difficult to imagine that Junk English will be noticed, much less read, by those who most could profit from it—but it is an instructive and entertaining instructions and explanation all the same. He tries his hands at all the right places—jargon, cliches, euphemisms, and exaggeration—but he doesn’t swing blindly. "Although jargon often sounds ugly to outsiders, it speeds communication within the community that uses it"—and that "clich6s, though popular objects of scorn, are useful when they most compactly express an idea; deliberate avoidance of an appropriate cliche sometimes produces even worse writing." In other words, Smith may be passionate but he’s also sensible. In a section about "free-for-all verbs," for example, he acknowledges that "There is no law against inventing one’s own verbs" before citing a few funny instances of what happens when "Things get a little out of hand," i.e. "We’re efforting to work this out" or "She tried to guilt him into returning the money." In the end, though, being sensible about language is in essence trying to insist that words mean what they properly mean and are used accordingly. Thus, for example, Smith insists that "dialogue" and "discussion" are not synonyms and should not be used interchangeably; that "complimentary" does not mean "free"; that "experience" does not mean "feel"; that "facilitate" does not mean "ease"; that "generate" does not mean "produce"; that "lifestyle" does not mean "life". Smith obviously has spent a lot of time making notes about the ways in which we min and abuse our language, with results that are impressive in their thoroughness and depressing in their going to far. Occasionally he overlooks the obvious—among euphemisms he mentions "customer care representative" but not "courtesy call," and among the previously mentioned palsy-walsy language he inexplicably overlooks "Your call is important to us"—but then, as he says at the outset, he intended to write a short book and as a result had to leave out many misdeeds. The ones he includes more than do the job. What would the author do with Ken Smith’s Junk English
某宾馆框架结构，总建筑面积10000m2，土地使用年限为40年，2003年年初通过出让方式取得。三年后，该宾馆建成并投入运营，一层建筑面积2000m2，其中500m2为宾馆大堂，1500m2用于出租餐厅和咖啡厅，其余各层为宾馆客房、会议室和自用办公室。该宾馆共有客房190间（建筑面积7600m2），会议室2间（建筑面积200m2），自用办公室3间（建筑面积200m2）。当地同档次宾馆每间客房每天的房价为200元，年平均空置率为30%。会议室的租金平均每间每次500元，平均每间每月出租20次。附近同档次一层商业用途房地产的正常市场价格为每平方米建筑面积15000元，同档次办公楼的正常市场价格为每平方米建筑面积8000元。该宾馆正常经营平均每月总费用占客房每月总收入的40%。当地宾馆这种类型的房地产的报酬率为12%。试计算该宾馆的正常总价格。
