Last night I had a very strange dream. I dreamt I 1 an alien(外星人) in my school! I asked him where he was from 2 why he was here. He told me that he was from Mars and won a competition to 3 the earth. I asked him4old he was and he told me he was 500 years old. Then I asked him how long he was going to stay on the 5 and when he was going back 6 Mars. He said that the earth was so7 that he didn't want to leave. He also invited 8 to visit Mars one day. 9I heard my mum calling me, "Wake up, Peter. Time for10 !" What a strange dream!
