Dear Diana,
Thank you for the lovely day we have with you. It was so kind tor you to let us bring Anne's friend. Gina. Unfortunate, the only problem was the journey home. There had been a terrible accident on the highway and, for a result, there was a long line of traffic for at least six mile. In the end, we drove to a service station and waited there unless the road was clear. In the car park Gina nearly got knocked over as a car drove out far too quickly from behind a lorry. They finally dropped Gina off at her parents' and made our own way to home.have→had
网友回答
(答案→)have→had
解析：
【小题1】由后面的was可知，这儿应该用过去时态。
【小题2】It’s kind of you为固定用法。
【小题3】这儿用副词作状语。
【小题4】as a result固定搭配。
【小题5】mile是可数名词，并且前面是six.
【小题6】这儿后面一句是一个时间状语从句，意思是我们一直等到路通了。
【小题7】叙述的是别的地方发生的事，所以用there.
【小题8】car不是特指，并且是可数名词，所以前面要加a.
【小题9】叙述的是我们做的事，所以用we.
【小题10】make one’s way home中home为副词，所以前面不用介词to。
