there have been以及后面人称和时态不同的2种都是 there be结构的完成时态,have+done,你看出来了么~
意思就是“已经有……了”
用had的那个肯定就是过去完成时了,用has的那个,当然就是have的第三人称单数了.
例如
there have been many people missing.很多人都已经不见了.(现在完成时,不用在第三人称单数,因为have)
there had been many people/much money missing.很多人/钱都已经不见了.(和上面一样,时态不同而已,变成过去完成.单复同型)
there has been much money missing.很多钱都不见了.(只能用在单数,因为是has.)
