范文
　　Directions: While your family was on vacation, your friend, Cathy looked after your dog, smart. Now you came back, write a letter to her to show your gratitude. Your letter should be no less than 100 words. You don't need to write the address. Don't sign your own name at the end of the letter, use Emily instead.

Dear Cathy,
　　I am writing to express our heartfelt thanks for taking good care of smart while we were on holiday. He was such a happy dog when we got home; we knew he must have had lots of loving attention. When we used to pick up from the kennel he would whimper and carry on for hours.
　　You not only saved us some money, you also spared us the worry of how he was doing while we were away. Your kind help is very much appreciated, not only by smart, but also by our whole family as well.

Yours truly,
Emily

译文
　　我写信是要谢谢在我们度假期间你帮助我们照顾小狗。我回来时看见它是那么高兴，就知道你对它一定很好。以前每次度假回来，去寄存中心接它时它总是非常难过，要持续几个小时。
　　你不但帮我们省了钱，也使我们免于对于它的担心。对于你的帮助我们都非常感谢。

你真诚的：艾米丽
