例98　Behaviorists, in contrast, say that differences in scores are due to the fact that blacks are often deprived of many of the educational and other environmental advantages that whites enjoy.

【结构分析】这句话主干是Behaviorists say...，后面加上宾语从句that differences in scores are due to the fact...，宾语从句里面套上同位语从句that blacks are often deprived of many of the educational and other environmental advantages...，同位语从句后面套上定语从句that whites enjoy。

【亮点回放】此句话的亮点在于宾语从句套上同位语从句，再套上定语从句，注意后面两个that很难区分到底是定语从句还是同位语从句，这个区分需要长时间练习，due to the fact这种结构的成功使用是这句话的亮点，比一般的because引导的状语从句强。

【核心词汇】

behaviorists　行为学家

in contrast　相反地

differences in scores　分数上的差异

due to　由于

deprived of　剥夺

educational and other environmental advantages　教育和其他环境上的优势

【参考译文】相反的是，行为学家认为，白人和黑人在考试分数上差异是由于这样一个事实，也就是说黑人被剥夺了白人所享受的教育和环境上的优势。
