考题讲解

题目分析：本题划线部分较长，主要的意思是：
美国的一个数据，在1975年有1/3小孩的妈妈不是家庭主妇，而在2000年有2/3孩子的妈妈是不做家庭主妇的。

选项分析：

选项A：while连接的两个句子不具有对比关系。这点实际考查了句子的核心词。while身后是there be句型，其核心词为“有”即：
这里有1/3有孩子的妈妈
在逻辑上，具有对比关系的两个句子应为：“1/3的妈妈在1975年工作在外”和“2/3的妈妈在2000年工作在外”。即，对比对象应该是两个年份不同比例的妈妈的“工作”情况。

选项B：核心词错误同选项(A)。

选项C：Correct. 本选项在语法和逻辑上均是正确的。

选项D：首先，应将even though改为while或者whereas。这是因为，两个年份孩子的妈妈工作的情况之间应该是对比关系，而不是转折关系；另外，核心词错误同选项(A)。

选项E：本选项一开始的with about one-third of mothers with young children working outside the home in 1975是独立主格结构。依据图形背景原则，若本选项正确，则独立主格中的work这个动作必然在持续时间上长于主句的employ这个动作。但在本题中，两个动作处于两个年份，无法判定谁持续的时间长于谁，因此，只能用两个独立的句子来表达。
