be going to have done 是将来完成时吗?

be going to have done 是将来完成时吗? 英语翻译be to do 和 to be done 是都表示将来吗?to have done 和have done 是不 be going to 是现在进行时表将来吗 should have done 与could have done 都是过去将来完成时吗 be going to 是一般现在时表将来吗 woud have done是什么时态,是将来完成时,还是现在完成时的虚拟语句? 不定式表将来,那么to have done表示什么意思,表将来完成?不定式一定表将来吗?可是像I am so glad 英语翻译have worked hard Have done 是完成时吗?exactly what to have done/to be done 将来时有BE DOING么?be going to do和BE DOING是算在现在进行时表将来? 将来完成时不是 shall（will）have+过去分词吗?可是will have been done 与will ha to have done怎么理解,这个是不定式的完成时,可以举例子说明吗?
