问题描述:

We ought to have received the parcel yesterday,but it didn’t arrive
为什么ought to +have received?
不是原形吗?怎么好像是现在完成时?(have received)我刚刚上初二,是我猜的,

翻译:昨天我们本应该可以收到包裹的,但是(现在)还没有来.
have received是现在完成时,现在完成时用来表示之前已发生或完成的动作或状态,其结果的确和现在有联系.动作或状态发生在过去但它的影响现在还存在;也可表示持续到现在的动作或状态.基本结构:主语+have/has+过去分词(done).
