"two years ago "不是表过去时吗?为什么可以与现在完成时连用?(since two years ago)而when就不可以?
"two years ago "是表过去时,但和since连用表示的是现在完成时,since+一个过去时间是现在完成时表示时间的一个方法,等同于for+一段时间的用法
when引导时间状语从句,后跟点时间,而two years ago已经是一个确切时间,不需要when引导
two years ago是只的那时的时间
而since two years ago指的是从那以后到现在的这一段时间
表示一段时间才能与完成时连用
two years ago 不是表过去时吗?为什么可以与现在完成时连用?(since two years ago)而when就不可以?
since two years ago 中但是ago不是标志过去式吗?不矛盾吗这个句子不矛盾吗?
