我不快乐(I was not happy)
One day,I went into my house.I played computer games.That game was “the house of the dead”.I said:“Maybe it was very easy”.The game began.I saw some old houses.Then a headman came to hit me.I shot him with a gun.He was died again.I was afraid.Later on,I killed many dead men,but I died once.Finally,I saw a very very very big monster.It hit me.I shot it at once.But I failed.I thought it was very hard.I began to shoot its head.But I failed again.I began to shoot his body.I shot its body many times,the monster died in the end.I don’t like this game.Because the dead men was ugly and horrible.
I began to play another game:Dune 2000.I completed many mission.I was happy.
But,at that time,it was one o’clock; I must went to school to learn Olympic Maths.I don’t like it.Because,I must learn it two hours!I don’t like it!
So,I was not very happy that day.
