足球赛已经开始半个小时了，我们错过了一个进球用英语怎么说

这个回答明显有语法错误，miss用错了时态，应该是missed或者have missed。正确的说法可以是：We've missed a goal since the match started half an hour ago.

这句话其实有点Chinglish的味道。更地道的说法是 "The match has been on for half an hour and we missed a goal." 注意时态，missed用过去时更准确，因为那个进球已经发生了。

其实更地道一点可以说：We missed a goal because the match has been going on for half an hour. 原句的时态和语境稍微有点生硬。

这翻译有点中式英语的感觉诶。"has begun for half an hour" 这种说法在英语里不太自然，通常我们会说 "The match has been on for half an hour"。而且 "miss one goal" 也有点奇怪，如果是“错失/没看到”一个进球，用 "missed a goal" 可能更贴切，或者更地道的 "we missed a goal being scored"。建议改一下，不然老外看了会困惑。
