90、 The increase in the numbers of married women employed outside the home in the twentiethcentury had less to do with the mechanization of housework and an increase in leisure time for these women than it did with their own economic necessity and with high marriage rates that shrank the available pool of single women workers，previously，in many cases，the only women employers would hire.

二十世纪已婚妇女在家庭以外就业的人数不断增加，这与家务的机械化及这些妇女闲暇时间的增加并无多大联系，更多地是与妇女自身的经济需要和高婚姻率相关。高婚姻率致使所能雇佣的单身女工的总量缩减，而在此之前的许多情形中，单身女性则是雇主们所愿雇佣的唯一—一类妇女。 The pool of 如果后面跟着一群人，则表示劳动力资源
难句类型：复杂修饰、插入语
