Many tall buildings ___(build)in our city during the last few years.
不能用现在时态,因为人家明明写着during the last few years.
过去完成时也不对,没有一个过去的时间或过去的动作作参照,只有一个过去的时间,就是在这个时间内发生的动作所以应该用过去式,were built

had been built
during the last few years 在过去一段时间段里,要用过去完成时
又因为高楼是被建的,所以要用过去完成时的被动语态

have been built

Many tall buildings _have been built__(build)in our city during the last few years.

were being built

were built

用现在完成时
have been built应用现在完成,应为是 对现在的影响,此外还有during

have been built
during the last few years指在过去的几年间,应用过去完成时
因为Many tall buildings是被建造的,所以应用被动语态
