Most studies suggest that when women and men do the same job and have the experience, pay rates tend to be similar. Most of the dollar differences stem from fact that 71. women tend to be more recently employed and have more 72. years on the job. Whether women who have started a career will attain pay equality with men rest on at least two factors. 73. First, will most of them continue part time at their jobs after 74. they have children? A break in their employment, or a decision 75. to work part time, will slow its raises and promotions because it would for men. Second, will male-dominated 76. companies elevate women to higher-paid jobs at the different 77. rate as they elevate men? On some fields, this had clearly not 78. happened. Many men, for example, have committed their 79. lives to teaching careers, yet become 80. principals or headmasters.
答案： 71. from fact -> from the fact 72. recently -> frequently 73. rest -> rests 74. part -> full 75. its -> their 76. because -> as 77. different -> same 78. On -> In 79. men -> women 80. relative -> relatively
become 80.
