Question

has been 一问
1.The use of documents helps to confirm details of a transaction that HAS BEEN agreed verbally.
2.A document is used to prove the buyer HAS ORDERED the goods.
我想问问,这两个句子 为什麼1要加been ,2不用?（大写部分）.

Answer 1

第一个用是因为是被动语态,transaction be agreed verbally.transaction自己不能同意,而是人去同意交易,交易被同意.
第二个buyer HAS ORDERED the goods.是主动语态,是买方订货,所以不用be
