Question

---Is the Youth Center open to the public yet?
---Yes. It ______ for almost one and a half years.

A．has opened	B．has being opened
C．has been open	D．was open

Answer 1

C

試題分析：句意：青少年中心對公眾開放了嗎？——是的。已經(jīng)開放幾乎一年半了。結(jié)合語境可知下文描述的是一直持續(xù)到現(xiàn)在的動(dòng)作，故用現(xiàn)在完成時(shí)態(tài)。Open用作動(dòng)詞表示瞬間動(dòng)作，不能和表示一段時(shí)間的時(shí)間狀語連用，故選C。
