一手掌控：大學英語六級考試閲讀單詞：第十八期

[背景了解]
　　文章取自於2004年1月的閲讀真題，是關於職業女性的文章，選段有點長，希望耐心看下，自己先猜下劃線部分單詞的意思吧
　　[文章部分]
　　Some futurologists have assumed that the vast upsurge (劇增) of women in the workforce may portend a rejection of marriage. Many women, according to this hypothesis, would rather work than marry. The converse (反麪) of this concern is that the prospects of becoming a multi-paycheck household could encourage marriages. In the past, only the earnings and financial prospects of the man counted in the marriage decision. Now, however, the earning ability of a woman can make her more attractive as a marriage partner. Data show that economic downturns tend to postpone marriage because the parties cannot afford to establish a family or are concerned about rainy days ahead. As the economy rebounds, the number of marriages also rises.
