Great changs have already taken place in Yancheng. A second expressway(高速公路) _________(build) through the city a few years after the first one was done.
答案是 was built,为什么是过去时?后面a few years after the first one was done应该是一个整体吧~~判断不出啊~

我认为a few years after the first one was done说的是过去，且前句Great changs have already taken place in Yancheng中already`have等都能说明。高速公路当然是被建，所以用be。
根据句子的意思来看啊。而且你短句子断错了。
a few years after the first one was done，不能连起来看。应该看成 a few years ，after the first one was done，所以就是实际上已经建成了的。当然用过去式了。
was built，被动语态，高速公路实在过去的时间里建造的，整个语段都是过去时Great changs have already taken place in Yancheng。说明了事情是在过去发生的。
