2. But particularly when viewed against America’s turbulent past, today’s social indices hardly suggest a dark and deteriorating social environment. [2006, text 1]
分析:
A.分析句子結構。該句的主句是today’s social indices hardly suggest a dark and deteriorating social environment,謂語動詞是suggest。when引導時間狀語從句。
B.分析省略結構。該句中的when引導時間狀語從句為省略形式。當從句的主語與主句的主語一致時才可以省略,所以該從句的主語是today’s social indices。狀語從句補充完整是when today’s social indices are viewed against America’s turbulent past。
