Dear Mom and Dad
We’re having a wonderful time in Australia. There is so much to see that it is impossible for me to tell you everything. During the past three days, 我们已经在悉尼(Sydney)四处游览了一番. We climbed the bridge, where we could get a really good view of the city.We also went to the zoo,  where we saw many animals that can only be found in Australia. We spent some time relaxing in the sunshine at the beach, and then we went to Pitt Street and wandered around for a bit while we did some shopping. Though I would like to spend more time here, the local guide told us that we would fly to Cairns（凯恩斯）tomorrow. 据说那儿大海非常美, where many different fish live. Now everybody is busy packing in order to save time when we get up tomorrow. This time tomorrow we will be enjoying the ocean near Cairns. I can’t wait.
Though I have much more to tell you, I must go to bed now so that I can get up early and get to the airport on time. 请向奶奶致以我最好的祝福and tell her that I am coming back soon.
Love
Robert
