Oral Presentation - Dust Storm - amended

When I was twenty-six years old, I went to a desert in China. I went there with my friends and we planned to stay for about one month. We were very happy there, because there were many animals for us to study. However, China had been desertified and there were many dust storms. The storms had given us a lot of trouble. We dug a hole to live underground.

The hole was very safe and we could continue our trip. When the storm left, we went out of the hole and saw the sky turned yellow. We were very surprised when we went back to Hong Kong because of the air pollution. The air pollution had become very serious because of the dust storm and it had broken Hong Kong’s record.
