15.Last night,I dreamt about a great flood. It was nine o'clock in the morning.My bedroom floor was a pool of water.I looked out of the window.Water was everywhere. (A)It covered roads,parks and small houses.Large objects,such as coaches and boats,passed by my window.They were floating in the water.I could not just stand there!I had to do something! I (B)called my dad,but the line was dead.My computer was still working, (C) I sent him an email.I wrote, " Dad,there is a flood!What should we do?" He sent me an email back which said "Kevin,my boss has given me some work.It's important to stick (D) it.I can't afford to sit around and worry about the flood" Then I emailed my best friend. "What should we do about the flood?" I asked.My friend (E)answered, "I have no time to think about the flood. (F)我在玩電腦游戲…" I shouted, "The WATER!Look at the WATER! " But my cries fell on deaf ears.In offices and homes,people just sat and stared at their computer screens.It seemed that they did not want to leave.Computers were more important than the flood. Very soon,the water came into people's rooms.It poured onto their desks and covered their computers.In surprise,people finally started to notice the flood,but it was too late. Then I woke up.There was no water.I was safe —— for now.
