问题描述：
I believed by the end of that year an advanced version of that software would have been developed,but I was wrong .
如何正确使用好过去将来完成时,里面的 would have been developed的been去掉行不行,还能用么`?
答
不能去掉,这是表示被动.主动时不用它.
答
当然不能去了，develope的 主语是software ，二者是被动关系。其实过去将来完成时很好学，关键是你能不能理的清句子中间的各主语与谓语关系，以为这是复杂句，所以只有把简单句学好以后，复杂句就好学了。平时学习时多想想一个句子是怎么来的？祝你成功。
答
I believed by the end of that year an advanced version of that software would have been developed,but I was wrong .
译：到那年年末我相信那个新的软件的先进版本已经被发明,但是我错了.
析：因为would have been developed在此句中是表被动,因此不能去掉“been”.
过去将来完成时
should / would have done sth.
用法
1、 过去将来完成时表示在过去将来某一时间以前发生的动作,并往往会对过去将来某一时间产生影响.
2、 过去将来完成时还常用在虚拟语气中,表示与过去的事实相反.
