It was only in the last decade when both political and social changes took place that women were finally granted the freedom to love who they wanted to love.
这个句中的when强调the last decade, 请帮忙分析下这句子,这句子如果是强调句型,而在强调句型的基本结构应该是:it is ...that... ,那这个when横在当中是怎么回事呢?难道when在此引导的是定语从句?我现在比较晕,大家帮帮我,谢谢。
是不是when both political and social changes took place 整个句子作为定语来修饰the last decade?而基本句型还是it is...taht...的强调句?
