单选题 Public goods are those commodities from whose enjoyment nobody can be effectively excluded. Everybody is free to enjoy the benefits of these commodities, and one person' s utilization does not reduce the possibilities of anybody else' s enjoying the same good. Examples of public goods are not as rare as one might expect. A flood control dam is public goods. Once the dam is built, all persons living in the area will benefit—irrespective of their own contribution to the construction cost of the dam. The same holds true for highway signs or aids to navigation. Once a lighthouse is built, no ship of any nationality can be effectively excluded from the utilization of the light house for navigational purposes. National defense is another example. Even a person who voted against military expenditures or did not pay any taxes will benefit from the protection afforded. It is no easy task to determine the social costs and social benefits associated with public goods. There is no practicable way of charging drivers for looking at highway signs, sailors for watching a lighthouse, and citizens for the security provided to them through national defense. Because the market does not provide the necessary signals, economic analysis has to be substituted for the impersonal judgement of the marketplace.

完形填空 A high school history teacher once told us, 'if you make one close friend in school, you will be most fortunate. A true friend is someone who stays with you for life.' Experience teaches that he was right. Good friendship is just not easily 21 . It is possible that we simply do not stay in one place long enough for 22 friendship to developed. However, there can be 23 disagreement on the need for each of us to think carefully about the kind of friendship we want. To most of us, friendships are considered very important, but we need to have clear ideas in our 24 the kinds of friendship we want. Are they to be close or 25 at arm's length? Do we want to 26 ourselves or do we want to walk on the surface? For some people, many friendships on the surface are 27 enough—and that's right. But at some point we need to 28 that our expectations are the same as our friends' expectations. The sharing of 29 experience including our tears as well as our dark dreams is the surest way to deepen friendships. But it must be undertaken 30 and carried on only if there are 31 of interest and action in return. What are some of the 32 of friendship? The greatest is the attraction to expect too much too soon. Deep relationships 33 time. Another 'major difficulty' is the selfishness to think one 'possesses' the other, including his time and attention. So, friendships 34 actions in return, in other words, you must give as much as you take. Finally there is a question of taking care of. Unless you spend 35 time together, talking on the phone, writing letters doing things together, friend-ships will die away.

完形填空 One day, an expert in time-management was speaking to a group of business students. To make the point clear, he used an illustration. As he stood in front of the group, he said, 'Okay, time for a quiz.' He then pulled out a wide-mouth jar and set it on the table. Then he 21 placed about a dozen fist-sized rocks, one by one, into the jar. When the jar was filled to the 22 and no more rocks would fit inside, he asked, 'Is this jar 23 ?' Everyone in the class said, 'Yes.' 'Really?' Then he reached under the table and pulled out a bucket of gravel(沙砾,石子), dumped some in and 24 the jar, causing pieces of gravel to work themselves down into the space 25 the big rocks. Then he asked the group the same question. 'Probably not.' One of them answered. 'Good!' he replied. He reached under the table and 26 a bucket of sand. He started dumping the sand in the jar and it went into all the 27 left between the rocks and the gravel. 28 he asked the question. 'No!' the class shouted. 'Good!' Then he grabbed a can of water and began to pour it in 29 the jar was filled to the brim. Then the expert in time-management looked at the class and asked, 'What is the point of this illustration?' It is such a seemingly easy question that one 30 student raised his hand and said, 'It is, however full your schedule is, if you try really hard you can always 31 some more things in it.' 'No,' the speaker replied, 'The truth it teaches us is that you will 32 get them in at all if you don't put the big rocks in first. 33 the big rocks in your life are, do things that you love and value for yourself. In your schedule if you value the little stuff then you'll fill your life with 34 things and you will never have the real quality time you need to spend on the big, important stuff.
