am Professor Huang I have just invented a time machine. People can
travel into the past or the future for five hours with the time machine at a time. I thought that it would be fun to see what my father was like when he was 10 year oid . I took a small bag and got into my time machine. In a second ,I was in front of the old house, 11Niven Road, I saw four children looking for a last dog ,I knew them,They were them ,they wew my father,my cncle and my tow aunts. Iintroduced myself as a policeman. They asked me to help them look for the lost dog,Blackie
The children looked everywhere in the neighborhood,When we reached the farthest house,Isuddenly heard a dog barking ,The children knocked on the door of the house and asked the man, who came to the door ,to teturn Blackie to them ,The man asked the children to prove the dog was Blackie to them ,The man asked the children to prove the dog was Blackie and so my father called out Blackie's name and the dog answered with a friendly "woof woof" The man returned .My five hours were almost up ,so I said good bye to them and a second.I found myself back in my time .What an adventure!
