since后面要加完成时态哦~

C
since引导时间状语从句，从句一般过去时，主句现在完成时（且要用延续性动词），表示从过去时间点至今为止发生的事情。

C
她和我自从上个夏天认识到现在一直是好朋友
按意思可知是现在完成时
是朋友这个状态用been 因为made 是交朋友是非延续性的

C
你知道hung well么
恩，自从我们两去年夏天遇见之后就成为了朋友
make friends 交朋友但是只是一个短暂的过程或动作
be friends是强调一个状态
所以选c

C
凡是有Since, Due to, yet之类的时间状语，一律用现在完成式，have been表示一种被动式，在此，交友是个不可延续性的，主动的完成时态，但在此句中，这里的be后面不跟任何的动启，表示“成为”，所以先C。
