1. "So what your association is backing is a program which would allow the middle and upper classes to acquire a bomb while poor people will be left defenseless with just handguns." (2004. 阅读. Text 2)

　　【译文】1998年进行的上个政府调查预测冻土下有三百万到六百万桶原油，但没人确定冻土下埋藏原油的准确数量。

　　【析句】复合句。主句no one knows how much crude oil lies buried beneath the frozen earth, 其中，how much……earth是knows的宾语从句，buried beneath the frozen earth为过去分词作定语修饰crude oil。主句后with the last goverment survey projecting output……是with伴随结构，两个逗号见conducted in 1998为过去分词作定语插入语。
