   I had never seen sanddunes（沙丘）before. Ifyou go to the seaside in Britain, you may see some small hills of sand, butnothing very impressive. Of course, Africa is home to many beautiful“sandscapes”, but I was in China, so I went to Dunhuang.

I had spent my first day looking at thebeautiful Mogao caves. Now I wanted to experience something very different.

I have been walking in Asia, Europe andAmerica, but nothing prepared me for walking over hills of sand. Whenever Itook a step up a hill, my feet would sink into the sand and move backwards.Sometimes it seemed as if I were moving in the wrong direction.

I wanted to see the sunset so I had toclimb to the top of the highest sand dune. The sun was beating down upon myback as I walked slowly over the sand. Some plants had managed to survive inthe dry ground but not many.

As I climbed higher, the hills of sandbecame steeper and my feet started to slip further backwards. I ended up withmy hands and knees, crawling (爬行)upwards through the top. I just let go if I would fall the waydown. But I refused to give up: inch by inch, I made my way to the top of thesand dune.

When I got there I was amazed by what Isaw. The sand formed a very sharp point, just like a knife-edge. One side ofthe dune was bathed in sunshine, the other covered by shade. As I looked intothe distance, the same pattern was repeated on all of the hilltops, and thedifference between dark and light was beautiful.

As the sun began to sink, the shadows grewlonger and the light became warm and orange. The wind had come to life and sandwas blown against my legs as I walked along the dunes. Soon it was getting darkand I could only just make out the line of footprints that marked my journey tothe top of the hill. I slowly made my way down to the bottom, my path lit bythe dying sun.
