一 The day before yesterday.

We need to have a rest the mountain.

There was nothing , but I knew it was just there.

    We have been in Australia for three days. We re having a good time here. Australia is the sixth largestin the world. There is so much to see that it is impossible for me to tell you. Sydney is a beautiful city. There are many tall trees and colourful flowers around the houses and they are really beautiful. There are also some specialin Australia, such as kangaroos and koalas. They are really lovely.

    During the past three days wemany places of interest around Sydney. I'd like to spend more time here. But we will fly to another city, Cairns, to see coral reefs (珊瑚礁) tomorrow. It is said that words cannot describe the beauty of the colorful coral. Many famous cartoon films were made there. Now we are busy packing our bags so that we will not miss the plane when we leave. We canin Cairns this time tomorrow. I'm expecting to go there!

一 It's three kilometres.
