•We received on February 7 the xx goods that we have ordered, but …

该句定语从句中的时态用现在完成时是否正确？可否改成：

•We have received the xx goods that we ordered on February 7. but … 

【答】改错题的答题原则是：只改正语法错误，不能改变句意。

首先判断，We received on February 7 the goods that we have ordered, but … 是错误的。（错误原因见后面的分析）

改正的办法：

1. We received on February 7 the goods that we have ordered, but …（误）

2. We received on February 7 the goods that we had ordered, but …（正）

【翻译】我们于2月7日收到了我们订购的货物，但是......

若改成网友下面的句子，语法虽正确，但意思变了：

3. We have received the goods that we ordered on February 7. but … 

【翻译】我们已收到了2月7日订购的货物，但是…

对比两个翻译，即可看出两句话的意思差别，相去甚远。

句1 错误分析：

1. received 这个动作，在February 7 已经发生，而早于received 的 “订购”动作，需要使用过去完成时（had ordered），这叫做“时态呼应”。按照过去完成时表示“过去的过去”理论，即可理解。

2. 如果把主句和定语从句分成两个互不相干的单句，则都是正确的。

We have ordered some gooods.

We received the goods on February 7.
