Football is, I suppose, the most popular game in England. In some important matches, you can see the rich and the poor, the young and the old all there, shouting and cheering for one side or the other.

One of the most surprising things about football in England is the great knowledge of the game which even the smallest boy seems to have. He can tell you the names of the players in most of the important teams. He has photographs of them and knows the results of a large number of matches. He will tell you who he expects(预料) to win such and such a match(诸如此类的比赛).

The schools arrange(安排) games and matches for their pupils. Football is a good game. It is good exercise for our body. It needs skills(技能) and wisdom(智慧) and it is popular and cheap. As a result, it is the school’s favorite game in winter.

根据短文内容判断下列句子的正(T)误(F)。

小题1:Many people in England like football.

小题2:It is the strangest thing in England about football that people shout and cheer for oneside or the other.

小题3:The reason why the schools arrange football games for pupils in England is that it’s very interesting.

小题4:Even the smallest boy seems to have a great knowledge of football.

小题5:Football is a good game, but it is not cheap.

题型:单项选择题

据有关媒体报道,在我国,排污权交易的第一个典型案例出现在江苏省。2002年夏,江苏省太仓市计划扩建太仓港环保发电有限公司,但在设计方案中每年二氧化硫排放超标2000吨,工程面临搁置的困境。而当时南京下关电厂每年二氧化硫的实际排污量比核定量少了3000吨。于是在江苏省环保厅的协调下,双方实施排污权交易。从2003年7月起至2005年,“太仓港”每年从南京市下关发电厂异地购买1700吨的二氧化硫排污权,并以每公斤1元的价格支付170万元的交易费。双方还商定到2006年之后,将根据市场行情重新决定交易价格。交易的结果看起来是皆大欢喜,但事情并不都是这么简单。

排污权交易在我国还面临着诸多问题:由于普遍技术水平较低和缺乏环保资金,减排的供应方严重不足,大部分企业排污都处于超标运行状态,自顾尚且不暇,何来余力出售减排指标?另外,如果企业向环保部门“寻租”的成本低于购买减排指标的费用,还可能带来“寻租”腐败等问题。不能指望能够找到一种完美制度让所有的问题迎刃而解,我们所能做的,只是在种种的备选方案中挑选出最优的一种选择。依靠一种以经济为诱因的制度,把环保问题纳入市场经济的轨道,让“看不见的手”自发地进行调节,从而降低减排的成本,最终达到控制污染物排放总量的目的,这恐怕就是目前人类能够选择的最佳路径。

在分析不同的组织或市场交易过程中,交易费用的分析维度为()

A.确定性、匹配性和成本—收益分析 

B.确定性、交易重复出现的频率和成本—收益分析 

C.不确定性、匹配性和成本—收益分析 

D.不确定性、交易重复出现的频率和资产专用性
