Hi Patrick,
Thanks for asking me to go to your birthday party this
Sunday. I’m sorry, but I can’t go. I have to study for a test this
weekend. My memory isn’t very good, so I have to study a lot!
I am studying the history of Asia. Do you like history? It’s
interesting, but it’s not easy.
I am not busy next weekend. Maybe we can meet next
Saturday? I want to give you your birthday present.
Mary

     很遗憾，我不能去。

    嗨！帕特立克：
谢谢你邀请我这个星期天参加你的生日聚会。但很抱歉，我去不了。我
这个周末要准备一个考试。我记忆力不太好，所以要多学习。
我现在正在学习亚洲史。你喜欢历史吗？历史非常有趣，但不容易学。
我下周末不忙，我们能不能下星期六见面？我想送给你生日礼物。
玛丽
