They have been in the library since it had been open.
这句吗
since 引导的从句能用完成时吗?
自从她被车撞死后我一直很伤心怎写?
i am sad since she died of traffic.
i am sad since she was killed by car.
i am sad since she died on The traffic accident
i am sad since she died in The traffic accident
i am sad since she died of The traffic accident
怎么表示达一直
i have been sad since she died of the traffic accident.

Answer 1

since后面接一般过去时即可.they have been in the library since it was opened.(最好把open换成opened)
一般不说 have been sad,因为have been表示一直处于某种状态,你可以把sad换成 in sorrow.
I have been deeply in sorrow ever since she died of the traffic accident.
