为什么填 since

as it's reported,it is more than 150 years__big beb,a famous attraction in london,wa founded.为什么填 since
"As it's reported,it is more than 150 years_since_Big Ben,a famous attraction in London,was founded."
据报道,伦敦的一处著名景点,大本钟始建于150多年前.
since:自.以来.所以直译是,据报道,自伦敦著名景点大本钟建成以来,已经过了150多年.
注：since通常是与现在完成时连用的.
所以原句应该是这样的：
"As it is reported,it has been more than 150 years _since_Big Ben,a famous attraction in London ,was founded."
据报道,自伦敦著名景点大本钟建成以来,已经过了150多年.
仅供参考.

那你觉得应该填什么呢？你把你觉得应该填的告诉我，我帮你排除吧！
至于since,请看后面be founded，是一般过去式，所以强调的是一个动作，Since加动作，前面是一段时间（150年），就表示从那个动作开始，已经有多少年了。
还有什么问题，继续问。after为什么不对...
