语法分析I still remember how many years ago__it was that______I last met her in the countryside.

语法分析I still remember how many years ago__it was that______I last met her in the countryside.
答：是句法分析
主句：I still remember
宾语从句：how many years ago__it was that______I last met her in the countryside
从句分析：
这是由一个强调句型的特殊疑问句变过来的宾语从句
原强调句It was 30 years ago that I last met her in the countryside.
不强调，原句为：
I last met her in the countryside 30 years ago.
译：我30 年以前在乡下最后一次遇见她。
主语：I, 谓语met, 宾语：her, 地点状语：in the countryside 时间状语：30 years ago, last
就30划线部分提问：
How many years ago did you last met her in the countryside?
就how many years ago 强调：
How many years ago was it that you met her in the countryside?
不过，这是一个问题，与I still know不搭配。知道的是一个事实。
所以，这一句话还有另一个解释：是强调方式（如何见面的方式），how 与many years ago不是一个意群的，many years ago本不应放入被强调部分的：
I still remember how__it was that______I last met her in the countryside many years ago.
我仍然记得多年前我在乡与她后一次相见的那个情境。
感觉how many ...引起的名词性从句多为“疑问型”，没有“名词型（肯定式）”的。
不过也许这题就是名词性（肯定式）
I still remember how many years ago__it was that______I last met her in the countryside.
译：我仍然记得是多少年前我在乡与她后一次相见。
说还记得是多少年，可就是说不出！
