英语四级译文:
这项研究中那些高效的妈妈们在孩子语言发展中可能已经产生了很大的影响，潘克索法尔女士说，“也可能是母亲起作用的方式在这次研究中并未测量到。”

四级词汇讲解:
本句的主干是Ms. Pancsofar said。之前的内容是间接引语，为said的宾语，其中that引导的是表语从句;引号之中为直接引语，也是said的宾语，其中that引导的也是表语从句，该表语从句中we didn't measure in the study是way的定语从句。

have an influence on的意思是“对……产生影响”。如:

This novel had a major influence on the youth.
这部小说对年轻人产生了重要影响。

measure在句中作动词，意为“衡量，测量”，此外它还有“仔细考虑，较量”之意。
如:As a writer, she always measures her words.
作为作家，她总是用词考究。
