It was a dark and stormy night．I was about to go to bed when I heard a tapping sound on my
window．
"Who's there?" I shouted．Suddenly there was a flash of lightning; I saw a face at the window．It looked like an alien （外星人） ．．．an alien that I had seen on the television show, "the X files".
I felt very scared．I ran to my bed and pulled my blanket over my head．I started to shout for my parents but there was no reply．Then I remembered that they were at a fancy dress party．
