When I was not adding little things to my new home, I was busy learning about the animals and plants on the island, and about myself.
I discovered that the birds that lived in holes and rocks were good to eat.
One day I found an old bag that I wanted to use to store things in. Some old corn fell out of this bag and made roots in the dirt. Soon green barley grew from the seeds. When I saw these plants, I cried. They reminded me of England. When I was young I wanted to leave England for a life of adventure at sea, but now that I was trapped alone, I only wanted to return.
One day, when I was sitting by my little cave, I heard a terrible noise. The next moment much dirt came falling down the hill. There was so much of it that I was afraid it would swallow(吞没) me! I ran away and climbed over my fence using a ladder I had made. I realized that the island was being shaken by a terrible earthquake.
The earthquake soon ended, but then a terrible storm began. The sea became black and violent(猛烈的) and full of huge waves that crashed onto the beach. Thunder roared and lightning hit the water. The storm lasted for three hours, but when it finished, it began to rain. This was not the gentle, calm rain of England, but a rain so hard and terrible that I had to cut a hole in my fence to let the water pour out. Otherwise, my house would have been drowned(淹没) !
