董事会将在明天举行，你能回来参加会议吗？ 求助英语

LS面那个标点错了,应该说是语法错了","不能放在两个单独句子中间,加个and或者用";"就行了.还有就是can 有点不客气了 我觉得用could好,所以应该是:
The Board will be held tomorrow and could you come back to participate in the meeting?

The Board will be held tomorrow, can you come back to participate in the meeting?

The board of directors will hold in tomorrow, you can come back to attend the conference?
