这次习作可能是不少小朋友的最爱──想象哟!怎样才能写好以“未来的xx”为题的想象作文呢?
一、既然是写未来的事物,一定要具有新颖性。根据自己感兴趣的内容来组织材料。如未来的鞋,可根据现在的鞋子具有的特点,加上想象,设计出音乐鞋等。
二、针对自己所写的内容,要做到重点突出,有详有略。要突出它的样子、优点、结构、使用方法,而这些又侧重于样子、结构和使用方法,这几点要详写。
三、想象的内容要充实具体,切忌说空话。习作力争做到有美好的幻想,有科学的设想,又有具体形象的情景。
那么,怎样想象呢?
我是纪博士,我正在研究一种高科技的产品──“电脑厨师”。(开篇点题。
“厨师自动化”已不再遥远,只要在“电脑厨师”的“头脑”中放入一张食谱记忆卡片,它就可以准确地自动烹饪出中国、法国或意大利的各式菜肴。下面我向你们介绍一下它吧!
它的体积比一般的烤面包机略大,但却兼具煎、炒、煮、蒸等多种功能,其总重量也不过4.5公斤,在家居狭小的家庭中足以掀起一场“厨房革命”。(简介外形特点。
目前市场上销售的由电脑控制的烤面包机、发面机、电饭锅等都只能算是“低科技”产品,而且它们功能单一,但“电脑厨师”则可以说得上是一件非常精密的厨房高科技产品。它的组合包括一个微电脑处理器、一个小的变速机箱、一个记忆箱、一个记忆卡及一口锅。(简介内部构造。
使用时,只要把所有切好的食物材料装入机器上面的分隔器中,再将食谱记忆卡插入,电脑就可以根据卡中的指示,在适当的时候将食物放入锅中,何时应炒或翻面,什么时候用什么调料,都由电脑控制,只要把材料放好,就可以不管它,过几分钟回来,“电脑厨师”就会给你炒好一道可口的“电脑菜”,你将不必为自己的厨艺太差而担忧。(简介如何使用。
信息加创造等于21世纪。让我们携起手来一起去发明、创造吧!(发感想,发倡议。
老师评价:科技在发展,人类在进步,电脑早已走进了千家万户,但这离作者的愿望还有一段距离,电脑能代替一切人的活动吗?我们还不知道。这篇文章很有创意,能引起读者的探索兴趣,算得上一篇优秀作文哟!
