Sample

I thought this summer vacation at Aunt Jenny's would go as interesting as watching paint dry. That was an old house, One hundred years ago it was often filled with people coming to stay for the summer—it was such large, grand house that there would be thirty or forty guests at a time, and the host—my great grandfather was widely thought of as the smartest, funniest man of his age, so many people would come from all over the world to see him . But that was all in the past.Now the only person who lived here was Aunt Jenny, who lived in one small part of the house and kept the rest closed up.

Then I caught the sun shining in my eyes from a tall mirror in the hallway. “How pretty!It must be a hundred years old. If only I could go back and see my great grandfather!” I said, cleaning the dirt off the mirror with my hand. Suddenly, the shiny mirror became a sea inside it.The world began to spin, and I felt confused. Then, just like that, everything stopped. I looked around, and there I was with the mirror and in the same hall, but things were different , The family photos on the wall were now replaced by paintings of people I did not recognize.

The furniture all looked new but old fashioned at the same time.“I must be one hundred years into the past!” I thought to myself. Then a woman wearing old-fashioned clothing came down the hall. Drawing near, she frowned and said, “Oh, that won't do! The party starts in twenty minutes and you are still in casual clothes!What? You didn't bring anything? I've got a lovely dress I think it will just fit.” She led me away to her room and helped me get dressed like I was an old friend, and then together we went down to the parlour, which was filled with people dressed in fine clothes gathering around my great grandfather, listening to every word he said.

I spent the summer there, pretending to be a distant cousin from the city who was there on holiday. No one seemed to mind or care, as my great grandfather was quite wealthy and always had lots of guests. I tried to spend as much time as possible with my great grandfather and his friends, and it was the most wonderful time of my life. Then when the end of summer drew near, I went back to the mirror and rubbed it with my hand again.I found myself back in the same hall, but in modern time. Not a minute had passed. Then I realized that I still had a full summer ahead at boring Aunt Jenny's. “Now what am I going to do?” I asked  myself.

 Writing  Notes :

科幻故事写作属于想象性作文。要求创造出从未接触甚至根本不存在的新形象。允许自由想象、自主发挥的空间较大, 因此需要灵活的思维和丰富的想象力。科幻类作文包括两个主要因素：科学、幻想。科学既要有科学依据，要遵循科学原理。幻想是指对现实中不可能或者目前不可能发生的事情的奇特想象。因此在写作时要注意：可以有新奇大胆的想象但要有一定的科学知识作基础，要科学幻想而不是胡思乱想。可以从自己的生活出发进行幻想，寻找题材，可以就如何解决现实或者未来世界中会出现的问题进行合理想象。

主要步骤

一、确定主题

    把生活中碰到的、电视上或书上看到的各种科幻形象特点揉合，充分发挥想象力，创造一个生动的角色，确定作文的主题。

二、构思情节

    情节内容的设定要新奇，吸引人。充分发挥想象力，在科学基础上合理想象。比如写未来生活中的机器人，可以写外貌特征、功能，也可以写机器人的思想情感等。
