2017年12月大学英语四级翻译题库：科幻小说

　　请将下面这段话翻译成英文：

　　科幻小说是20世纪发展起来的一种文学体裁，科幻小说作家在其作品中描述科学发现、技术进步以及未来的事情和社会变化如何影响人类。对这些影响的描写，可能是对科学事实和原理的一种细致而有根据的判断，或是描写与这些事实和原理完全矛盾的令人难以置信的一些领域。

　　参考翻译:

　　Science fiction is a literature genre developed in the 20th century in which the fiction writer addresses how scientific discoveries, technological developments, and future events and societal changes affect human beings. The description of these influences may be a careful and informed extrapolation of scientific facts and principles, or it may range into far-fetched areas flatly contradictory of such facts and principles.
