Question

用英语写一个通知内容如下

通知
9月30日晚上7学生礼堂举行国庆庆祝会。我们邀请了著名的歌唱家作精彩表演。请同学们届时参加。欢迎老师们参与。（我只有20的财富悬赏，大家帮帮忙吧）
是7点。不好意思。少打了一个字！

这个↑是比较生硬版的，表示 学生们都得到场，老师们随便来不来，但是通知通常不这么说，会说大家都来吧。类似这样的↓：
NOTICE
At 7:00pm on September 30th，National Day Celebration will be held in the student hall. Several Famous singers will come for performances and everyone is expected to come.
The Students'Union

如果你是交作业，用上面的大概差不多，如果出通知，还是下面这个吧。仅供参考。
