问题补充：

I used to love that film I was a child, but I don’t feel it that way any more.

A. once

B. when

C. since

D. although

答案：

A. once

B. when

C. since

D. although

解析：此题考查状语从句使用的连接词。从句中I used to love that film.可知是过去的事情，所以只能用when 来表示是小孩子时发生的事情。

A项，“曾经” 句意不同，C项。自从，与完成式连用，D项 “尽管”与but 不能连用，而且句意也不通。
