关于未来科技的英语作文通用句子【一】
现在的科技已经越来越发达，科学家发明了一种宇航服，只要换上宇航服，就可以在各种星球走来走去。别看这件宇航服轻盈而又单薄，可它耐热、防寒，连去太阳或冰星都没问题。
可是时间长了，你会担心这件宇航服会氧气不足，宇航员会窒息而。你会想，可以在宇航服的头盔上接一个管子一直通到地球，可以吧地球上的空气传送到头盔，这样不就可以使宇航员不停地呼吸了？是的，现在已经有这样的宇航服了，但总不能让宇航员拖着长长的管子在星球上走来走去。有一位科学家作了改进，他在宇航服的头盔上装了一根天线，别小看这根天线，传送到头盔里，这样宇航员就可以在星球上不停地呼吸，不再担心停留的时间。宇航员就可以尽情的在其它星球上搞研究。
有了这种宇航服，地球上的人类就可以轻轻松松地移居到各种星球。这样，人类共同的家园扩大了，人类的太空梦也随之而实现。
关于未来科技的英语作文通用句子【二】
在超级计算机的top500排行榜上，自从日本nec公司的“地球模拟器” 被ibm公司的“蓝色基因”（blue gene）取而代之后，世界上运算速度最快的计算机之争又进入了一个新的阶段。nec公司正试图研制出运算速度更快的矢量计算机，而德国也正向这个顶峰发起攻击。
———题记
究竟是人类还是计算机厉害？这是个困扰了我们多年的问题。到现在还没有答案。在20xx年10月份举行的棋手与国际象棋计算机软件比赛中，许多业余选手一败涂地，并且由维赛林·托帕罗夫、鲁斯兰·波诸马廖夫和谢尔盖·卡尔雅金这三人组成的超强队伍竟以3.5比8。5的悬殊落败！这不禁引人深思：难道计算机软件真的`已经在人机对决中占了上风？人类真的将要败在以自己的智慧创造的计算机下吗？
为了迎接这场对决，参赛计算机的装备与以往大不相同。来自阿不拉扎比的hydra拥有16个处理器，而由英国人控制的计算机国际象棋世界冠军junior则拥有4个2。8hz的超强处理器……这使计算机的计算速度高出了人类许多倍，比人类更有优势，它在计算棋局的速度上是人类的几亿倍！然而下棋不仅要靠计算，还需要直觉，这是计算机所不具有的，在这一方面人类具有优势。但像谢尔盖·卡尔雅金这位12岁就成为国际象棋大师的天才，竟也败给了fritz软件，这使人们不得不深思一下了。
ibm公司推出的“深蓝”计算机棋手于1997年打败了世界顶级棋手加里·卡斯帕罗夫，其实不必惊讶，人类面对这款具有每秒分析2亿个棋局的计算机前，不论是计算能力还是分析能力，都将处于劣势。为了避免“深蓝”一开始就选择一个有漏洞的棋局，他们给“深蓝”配备了海量的数据库，这使普通棋手要想获胜就非常困难了。
但是计算机并不可能将整个棋局提前进行分析，对于一盘有40步棋的对局来说，其中可能的选择将会比整个宇宙中原子的数量还要多！没有计算机会如此高效率的进行分析，现在最优秀的国际象棋软件最多也只能计算30步棋，但这对于人类这个对手来说已经足够了！
我想，伴随着新的算法的出现、科技的进步，计算机将会越来越接近人类。

按要求改写句子知识点梳理
一、概述
按要求改写句子主要考查学生对句子结构的掌握以及用不同句型表达同一意思的能力。考查所涉及到的句子类型有一般疑问句、否定句、反意疑问句、选择疑问句、对划线部分提问、感叹句、保持原句意思、合并成一句、简单句和复合句之间的互换以及改为被动语态等。
二、解题时需注意的几个要点
1、时态：不同的时态相对应的助动词
一般现在时：谓语动词用原形（主语为第三人称单数时，动词加s或es，变否定句、疑问句时助动词为do或does）
一般过去时：谓语动词用过去式，变否定句、疑问句时助动词为did.
现在完成时：助动词have/has+动词的过去分词
过去完成时：助动词had+动词的过去分词
一般将来时：will/be going to +动词原形
过去将来时：would/was or were going to +动词原形
现在进行时：am/is/are＋动词的现在分词
过去进行时：was/were＋动词的现在分词
2、语态：主动语态变为被动语态的谓语结构
一般现在时：am/is/are＋动词的过去分词
一般过去时：was/were+动词的过去分词
一般将来时：will be+动词的过去分词
情态动词：can/may/must/need等情态动词＋be++动词的过去分词
3、改反意疑问句时注意hardly, never, seldom, few, little, no等词表达的是否定意义，变反意疑问句时用肯定形式。
4、在合并句子时，有些连词如not only…but also…, neither…nor…, either…or…是就近原则，连接两个主语时动词形式取决于与动词邻近的主语。而both…and…连接两个主语时,主语是复数。
5、简单句和复合句之间的互换常见的有：带有疑问词的宾语从句改为特殊疑问词＋to＋动词原形的不定式；结果状语从句so…that…改为enough to或too…to…的简单句。
6、保持原句意思改写句子时注意时态不变。
