since 用完成时指的是主句用完成时,而从句用过去时.
如：I have been here for five years since I came .
自从我来到这儿,我就在这呆了5年了.
主句是：I have been here for five years （完成时）
从句是：I came （过去时）
I have taught English for three years since I graduated from univerity.
自从我从大学毕业,我已经教英语3年了.
主句是：I have taught English for three years （完成时）
从句是：I graduated from univerity.（过去时）
希望对你有所帮助,如有不懂,欢迎追问.

since是现在完成时的标志，但since前的主句用现在完成时，since后的句子要用过去式。

赞同荷影纤纤的。since标志着主句是完成时，而since引导的从句时一般过去时。
再说这题就算不知道时态也可以用排除法。其它几项明显不通顺啊，表意和结构都有问题。

since有连词也有介词词性，在这里只强调时间，并未强调完成。
