62. Declaring that he was opposed to using this unusual animal husbandry technique to clone humans, he ordered that federal funds not be used for such an experiment-although no one had proposed to do soand asked an independent panel of experts chaired by Princeton President Harold Shapiro to report back to the White House in 90 days with recommendations for a national policy on human cloning.

65. If experiments are planned and carried out according to plan as faithfully as the reports in the science journals indicate, then it is perfectly logical for management to expect research to produce results measurable in dollars and cents.
如果试验是像科学杂志上的报告所示的那样如实地根据计划规划和实施的话，那么对管理层来说，期待研究能够产生可以用金钱衡量的结果是完全合理的。

Pluff! A hundred and eighty-five kilograms.

al journals harder for a mateurs, a result that has been reinforced by the widespread introduction of refereeing, first by national journals in the 19th century and then by several local geological journals in the 20th century.
这样一来总的结果便是业余爱好者想在专业地质学期刊卜发表文章就更难了，而被广泛使用的论文评审推荐制度又进一步强化了这一结果，该种制度先是出现在19世纪的国家级刊物上，后又在20世纪被几家地方级地质学刊物所使用。
82. A rather similar process of differentiation has led to professional geologists coming together nationally within one or two specific societies, whereas the amateurs have tended either to remain in local societies or to come together nationally in a different way.
