帮忙分析一下这句话的句子结构以及涉及的语法知识，尤其是made possible…那一段 new techniques of preserving food products made possible transportion over greater distances,in turn facilitating adjustments among locationg of production and consumption,with further benefits toproduction effiency

Answer 1

这个句子的结构是这样的： 主语+谓语+宾语+宾语补足语，+（动名词引导的）状语。
made前面的是主语，possible（定语） transportation（宾语）over greater distances（宾补），in turn（状语，相应的） facilitating后面的也是状语，表结果。其中，就facilitating 。。。这样看，adjustments是facilitating的宾语，among locationg of production and consumption介词短语后置定语，修饰adjustments，with短语做状语，表伴随，生产效率的更大的利益。
有不明白的，追问。

Answer 2

主语是 new techniques of preserving food products，

谓语是 made，这里的made possible 其实应该是 make something... possible的结构，即“使...成为可能”。在此是made (transportion over greater distances, in turn facilitating adjustments among locationg of production and consumption,with further benefits to production effiency) possible。但made后面的句子太长，有头重脚轻之嫌，所以就将possible的位置换到前面来，变成made possible。
宾语是 transportion over greater distances
宾语后面的 in turn facilitating adjustments among locationg of production and consumption,with further benefits to production effiency 是一个同位语从句，其实应该由which引导，即 (which) in turn...，which和transportion over greater distances构成同位关系，但此句里的which省略了。
