unmemorable

It allows me to know much about the Chinese people, its culture and its achievements. It was an unmemorable moment in my live.

它让我了解关于中国文化和中国人民的很多东西，对于我来说是一次很难忘的回忆。

The match, despite the rivalry between the two teams, was a fairly unmemorable game, rarely sparking into life.

尽管两支球队为宿敌，这场赛事却是一场完全不值得令人记住的比赛，极少出现火花。
