What he said already ___(记录)by the police.had been recorded

What he said already ___(记录)by the police.had been recorded
What he said already ___(记录)by the police.
had been recorded

What he said already ___(记录)by the police.had been recorded
What he said already has been recorded (记录)by the police.
他所说的已经被警察所记录
主语是:what he said
所以 谓语用 单数 has
被记录 :been recorded
我的是对的

marked

感觉这句话有错

用过去完成时是因为主语从句中的时态已经用了一般过去时.它是复合从句,不是并列句,所以句子的时态会受主从句的时态牵制.因为主从用了一般过,主句就不可以用现在的时态了,所以不用has been recorded,而要用had been recorded(过去完成时).
至于为什么要用完成时态.....那是初衷基本功...不加以赘述...
啊..看到2楼的回答突然想起来了.主语是个从句...
