As if a ghost had commandeered my pen and was writing toredress the injustices it had suffered

这里为什么用过去进行时和过去完成时， and 能连接吗

我不懂你的这句话是什么意思~~

首先as if 不恰当，用it is just like 会好一些

and 不要这样连接，也容易产生误解

这样就好了：

it is just like that the ghost which had commandeered my pen was redressing the injustices it had suffered。
