12. Your friend is getting married and he has invited you to his wedding. However, you can’t make it for a certain reason. Now write a letter to explain why.(谢绝信)
亲爱的Steve、Monica:
谢谢你们邀请我们参加你们的婚礼。不幸的是,我们无法前来了。
Dear Steve and Monica,
Thank you very much for the invitation to your wedding. Unfortunately, I won’t be able to attend.
