2018考研英語長難句分析指導(dǎo)（三）

　　Now since the assessment of intelligence is a comparative matter，we must be sure that the scale with which we are comparing our subjects provides a“valid”or“fair”comparison.

　　結(jié)構(gòu)分析:句子的主干是we must be sure…。since引導(dǎo)原因狀語從句the assessment of intelligence is a comparative matter。主句中又有that引導(dǎo)的賓語從句that the scale with which we are comparing our subjects provides a“valid”or“fair”comparison。此賓語從句中又套嵌一個(gè)由介詞with+which引導(dǎo)的定語從句with which we are comparing our subjects修飾先行詞the scale。scale在此處意為“尺度、衡量標(biāo)準(zhǔn)”。

　　譯文：既然對智力的評估相比較而言的，那么我們必須確保，在對我們的對象進(jìn)行比較時(shí)，我們所用的尺度能夠提供“有效的”或“公平的”比較。
