More families consist of one parent households or two working parents; 1 , children are likely to have less supervision at home than was common in the traditional family structure .
根据该空出现的位置,不难发现,此处需要一个逻辑连接词,将上下两个句子连接起来,因此,此处的分号是非常明显的引导标志;一般情况下,分号前后关系密切,仔细分析前后两句的意思:“More families consist of one parent households or two working parents”(单亲家庭或父母都有工作的家庭不断增加)与“children are likely to have less supervision at home than was common in the traditional family structure”(孩子可能在家庭受到的监督就可能比过去传统家庭要少),这两句之间是很明显的因果关系:更多的家庭只有父亲或者母亲在家,或者父母都在外工作。……孩子在家里面可能很少有人监督。因此选B项。
参考译文:
Families have also experienced changes these years. 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 .
