– Who bought those toys,do you know?
– Oh,they _____.They were the things we had made ourselves.
A.hadn’t bought them B.didn’t buy them C.hadn’t been bought D.weren’t bought
为什么?其中They were the things we had made ourselves.希望从语法的角度解释一下!
– Who bought those toys,do you know?
They were the things we had made ourselves 意思是它们就是我们自己做的东西,请注意 这个句子的主语THEY 是问句中的“Those toys”即那些玩具,所以答句中的“Oh,they.”这个they 根据前后一致的关系,they 就是那些玩具
再来看选项,A 选项 they (hadn't bought them ) 那么这个句首的主语,不是玩具,而是别人(他们),所以不对; B选项和A出现的问题一样,主语变成了指人,不符合题意
选项C,过去完成时,这个句子没有什么特别的时态,用这个时态不对
选项D,they (weren't bought) 意为:玩具还没有被买,过去式的被动语态,所以选D
