【正确答案】 B

【答案解析】[注释] 细节归纳题。本题问：根据本文，二战以后日本在环保方面没有采取措施的原因何在?第1段最后两句写道：“An insistence on treatment of the various effluents would have necessitated expenditures on treatment equipment that in turn would have given rise to higher operating costs．Obviously，this would have meant higher prices for Japanese goods，and ultimately fewer sales and lower industrial growth and GNP．”(坚持认为处理各种污染流出物将必须花钱购买处理设备，而这笔开支又会使运行成本提高。显然，这就意味着日本货的价格更贵，因而最终使销量减少、工业增长率和国民生产总值降低。)归结起来，日本人认为，环保投资会妨碍经济发展。故应选[B]。
注意：GNP(gross national product)国民生产总值。resort to(=adopt)采取。check vt．妨害，制止，阻止。例如：We have checked the advance of the enemy，(我们制止了敌人的前进。)
