There was a time in my life when people asked constantly for stories about what its like to work in a field dominated by men.
主干：There was a time
本句是个存在句，主语a time由when引导的定语从句修饰。about+what引导的宾语从句构成介词短语，作stories的后置定语在该宾语从句中，it是形式主语，后面的不定式短语to work...是真正的主语。dominated...作a field的后置定语。
译文：我生活中有那么一段时间人们老是问我，供职于一个男性占主导地位的领域感觉如何。
