英语作文的邀请函开头佳句加翻译

Im pleasing to invisit you for something at sometime on someplace.俺很高兴地邀请你来参加something,在sometime和someplace.上面这个有点老套,不过胜在实用.下面这个邀请虽然清新雅致,但相对有些固定,看作办哈：I will hold a （dinner） party at someplace on sometime to celebrate something. As you are a close friend of us, we would very much like you to participate in the celebration and share our joy.句子也不复杂,单词也不深奥,就不中文了哈.
