众所周知，考研英语的一大难点就是长难句。今天继续带领大家一起分析两个句子。
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.
【解析】句子主干是 How well the predictions will be validated by later performance depends upon...，其中How well the predictions will be validated by later performance是主语从句。这个主语从句的主干又是How well the predictions will be validated.同时后面的used是过去分词作后置定语，修饰information.本句最后的with which引导定语从句，修饰skill and wisdom，还原后为it is interpreted with skill and wisdom.
【译文】这些预测能在多大程度上为后来的表现所证实，取决于采用信息的数量、可靠性、适应性，以及解释这些信息所使用的技能和才智。
The policy follows similar efforts from other journals, after widespread concern that basic mistakes in data analysis are contributing to the irreproducibility of many published research findings.
【解析】本句的主干是The policy follows similar efforts。后面的介词短语after...findings是时间状语，其中还包含一个由that引导的同位语从句，解释说明concern。同位语从句的主干为basic mistake...are contributing to the irreproducibility...。
【译文】人们普遍注意到到数据分析的基本错误正造成很多已发表的研究成果无法复制，科学杂志就采用了多家其它杂志的做法。
