问题简答题

房价居高不下一直是近几年来我国经济发展的诟病之一。即使是在全球金融危机的情况下，我国房价也仅仅是在危机头半年稍稍做了做降价的样子，之后便又迅速恢复到危机前的水平。造成当前房价居高不下的原因很多，其中土地成本高，建材价格上涨，征地拆迁成本高，市政配套等行政事业收费高，经济适用房供应量不足，市场需求量大等都助长了房价的攀升之风。结合上述材料，从经济生活角度分析如何改变当前商品房价格居高不下的状况？(15分)

答案

（1）商品的价格是由价值决定的。（2分）土地成本高，建材价格上涨，征地拆迁成本高，市政配套等行政事业收费高都构成了商品房的成本，形成了商品的价值，在其他条件不变的情况下，价值量大，商品的价格就会高。（2分）要通过降低商品房的价值量（成本）来抑制商品房价格居高不下的现状。（3分）

（2）商品的价格受供求影响。（2分）经济适用房供应量不足，市场需求量大，产生了供不应求现象，商品房的价格随之上涨。(2分)要改善市场上商品房的供求关系，尤其要加大经济适用房的投入，保障城市中、低收入者的居住条件。（3分）

Americans have a great love for informality and nowhere is this better expressed than in their love for nicknames (昵称，绰号). Upon greeting strangers for the first time they will quickly introduce themselves by their nickname. These are shortened forms of their given name at birth and reflect the casual relationships which exist among friends and coworkers. Family names are hardly ever used in daily situations and the use of one’s father’s last name is saved only for rare and formal occasions.
In many traditional cultures the use of the family name is seen as a sign of respect. For Americans, however, it’s the nickname which creates an immediate intimacy between two people upon which to build a relationship. By speaking to another on a first name basis and using his nickname, walls are immediately torn down and equality between two people is established.
At work bosses will refer to their employees by their nicknames. Should an employer use a worker’s family name, you can be sure that some kind of correction or serious business will follow.
This love for nicknames can create a sense of closeness between people who are otherwise not related. Even the presidents of the United States have borne nicknames. Abraham Lincoln was known as Honest Abe. John F. Kennedy was known as Jack or JFK and William Clinton has no reservations in letting people know he prefers to be called Bill, but those who look upon him with disfavor may call him Slick Willy.
Not only people but cities often carry their own nicknames. Chicago is called the "Windy City" because of the p winds which come down from Canada throughout the year. New York City is considered the "Big Apple" for reasons which are still obscure to most people including many New Yorkers.
Not every nickname, however, is positive and some can be rather rude and insulting. If someone should demonstrate a certain negative characteristic, a label will soon be attached to describe that person in an unpleasant way.
Likewise a person’s physical traits which are very dominant may lead to nicknames but not necessarily to one’s liking or choice. A nickname, therefore, is a way of identifying or describing someone or something for better or worse.

Americans tend to use others’ family names ______.

A. on formal occasions
B. when writing letters
C. in the work place
D. when making phone calls
