问题描述:

it is said that he was failed again可以换成he is said to have failed again.
为什么是完成时,为什么用is,不可以换成,he was said to fail again

it is said that he was failed again可以换成he is said to have failed again.
动词不定式的完成时to have failed again表示该动作发生在is的时间之前;表明现在的时间用了is;
换成he was said to fail again就成了“他当时被说.....",而he is said to fail again是“他现在被说.....",

it is said that 是一个固定的搭配,意思是据说.而它的转换固定的就是sb.is said to do sth.不受时态的限制约束.完成时,从意思上说,就是已经失败,是已经完成的动作.这里实在搞不懂记住就可以了.英语中有很多这样的例...
