复杂的主语从句的拆分和理解 例46

例46　How well the predictions will be validated by later performance depends upon the amount, reliability, and appropriateness of the information used and on the skill and wisdom with which it is interpreted.

【结构分析】How well the predictions will be validated by later performance是个主语从句，动词是depends upon，第一组宾语是并列的名词，也就是the amount, reliability, and appropriateness of the information，后面加上分词定语used, and后面是第二个宾语the skill and wisdom，后面是定语从句with which it is interpreted，修饰前面的名词。

【亮点回放】此句话的亮点是经典的主语从句由how well来引导，后面的宾语特别复杂，第一个宾语是三个名词并列，后面第二个宾语是个名词，后面还套上定语从句。

【核心词汇】

predictions　预测

validate　证实

reliability　可靠性

appropriateness　合理性

interpreted　智慧

【参考译文】是否这些预测能被后面的情况所证明取决于信息获取的数量、可靠性、合理性，以及取决于信息被处理的技巧和智慧。
