某宗房地产交易的成交价格为30万元人民币，其中首期支付30％，余款在一年后一次性付清。该房地产公摊面积为建筑面积的10％，套内建筑面积为100㎡，假定折现率为6％，则该房地产按照建筑面积计算的实际单价为（）元／㎡。
A.2593
B.3298
C.3098
D.2998
参考答案：A
解析：一年后支付的款项要折现到首付时点后，再与首付款相加，才能得出实际价格。 首期支付30%，那么首期支付的价款就是30×30%＝9万，余下30×（1－30%）＝21万在年末支付，房地产实际价格＝30×30%+30×70%/（1+6%）＝28.811万元 建筑面积单价＝28.811/111.11＝2593.018868元/平方米，选A。
Passage Four
| Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more as of life to decision. In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least customary and undisputed. Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposite; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements. Furthermore, social change is easier if it is gradual. For example, it comes more readily in human relations on a continuous scale rather than one with violent changes. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities, because of the sharp difference in appearance between them and their white counterparts. |
