3、 感謝信
Jenny 邀請Jane在星期一參加生日晚會。但是Jane 那天晚上要參加數學考試，沒時間去。請幫Jane寫一封信表示感謝，她同時送上一份禮物，以示祝賀。時間是5月20日。
May20th,
Dear Jenny,
I'm glad to hear your good news. Thank you for inviting me to your birthday party. But I'm afraid I can't come. Because I'll have a math exam on Monday evening. Here is a gift for you. I hope you will love it.
Happy birthday!
Sincerely yours,
Jane
