Dear Toby,
Your trip sounds exciting! I can’t wait to hear ______ Africa is like.
Since my last letter to you, I have had a little adventure of my own. Early this morning, my mother and I took _______ flight to Dunhuang, in the north-west of China. The desert out there was really quite amazing—I had never seen _______ much sand in my life! While we were there, we arranged with a tour company to ride camels. I was really excited because this was the first time I had seen_______ up close. We had hoped that we could see some other wildlife on our trip, _______ sadly we didn’t.
Since you are going to the Sahara, I have some advice—be sure to bring a large hat and a shirt with long sleeves—you’ll need these _______ protection. The sun can be so brilliant that you’ll need to keep covered, _______ you’ll get burnt—my cheek were red for days after my trip. And another thing, you’ll need to keep a good supply of water with you, since it is so dry and hot.
Looking forward _______ receiving your postcards!
Best wishes
Aihua
