More families consist of one parent households or two working parents; consequently , children are likely to have less supervision at home than was common in the traditional family .
这个题目还是比较简单的,只要考生比较仔细,即便对前面的内容不是很理解,也是可以根据前面句子中出现的词汇来确定该题目的选项的。仔细在第三段的段首,“Changes in the social structure may indirectly affect juvenile crime rates”,指出了社会结构的变化会影响到青少年犯罪。因此,接下来,structure则是作为正确选项入选的。同时,考虑到其他三个选项的字面含义,我们可以将其他三个选项代入原句中,只有structure(结构,构造,建筑物)符合句意的要求“in the traditional family structure”(传统家庭结构)。
参考译文:
More families consist of one parent households or two working parents; consequently , children are likely to have less supervision at home than was common in the traditional family structure .
