以下是引用rock19840717在2008-7-3 16:54:00的发言:The computer industry's estimate that is loses millions of dollars when users illegally copy programs without paying for them is greatly exaggerated. Most of the illegal copying is done by people with no serious interest in the programs. Thus, the loss to industry is quite small, because__________ 我就发两个答案,别的无需多讨论 B) most people who illegally copy programs would not purchase them even if purchasing them were the only way to obtain them D) the total market value of all illegal copies is low in comparison to the total revenue of the computer industry 我就搞不懂了illegally copy不就已经是obtain了吗 OG的解释前半部分都没有问题,关键是从这里开始,他是这么说的:if it were true that most of them have no serious interest in the programs, they would be unlikely to purchase them, in this case, few sales would be lost and the loss to the industry could be considered small 他对D的评价又是:this comparsion is faulty: the loss is not being considered in the context of total industry revenues but in the context of total sales of programs 总的市场价值非常低无非的意思就是指vaule of illegal copies/sales of programs的比值了,有什么问题吗 首先,你說總的市場價值是value of illegal copies/sales of programs的比值,在理解選項方面是有問題的. D) the total market value of all illegal copies is low in comparison to the total revenue of the computer industry 這句話說的是A=total market value of all illegal copies ,B= total revenue of the computer industry,A小於B,而不是說A/B很小.這僅僅能說明A相對B是少的,不能說明A很少.這是相對值跟絕對值的問題. 關於B選項,如果不能copy只能買的話大部分人也不會去買,這說明了在不存在copy的情況下,銷售也不會增加,產家也不會賺到什麼錢 有copy沒賺到錢沒copy也沒賺到錢,對產家來說根本就沒什麼不一樣,自然也沒有什麼損失可言. |
