　参考答案与解析：

　　1、C　“第一次”英语为“the first time”.“the first time I met her”相当于一个时间状语从句“when I first met her”.“for the first time”作为第一次.

　　2、A 关系代词which在定语从句中作主语,代表the discovery.of great importance = very important.

　　3、B whatever, wherever, whenever, whoever, however引导让步状语从句,意思是"无论(做什么,在哪儿,在什么时候,谁,如何)",加强语气,要用陈述句的语序.
