现在的汽车有很多不方便的地方,所以我想设计一种新型汽车。
这种汽车使用的燃料是空气,廉价又环保。从此以后,你不再会为汽油涨价而忧心忡忡。他的车身是充气的,按一下充气按钮,他就能自动充气。你只要往车里一坐,就会有一种心旷神怡的感觉。开车时,你只要输入你想去的地方和速度,它就会自动到达指定地点。如果你想睡觉,就按一下变形按钮,车内就会变出一张床,供你休息。如果你饿了,它可以为你提供可口的饭菜……
现在不是常出交通事故吗?坐上了这辆车,你就不必担心了,因为你的车是由电脑驾驶的,车技高超。再说,如果真的撞到了人,被撞者的感觉就像是倒在了沙发上一样,毫发无损。
这辆车能变成船,带你一览水上风光;也能变成飞机,带你翱翔蓝天;它还能变成潜艇,带你去龙宫探宝……
这样一辆神奇的汽车,难道你不想拥有吗?
本次作文要求我们对未来的事物进行想象,这就要求我们的想象具有科学性。我们放开思想,抛弃传统思想的束缚,对20年后的飞机、电话、汽车、学校等进行大胆、奇特的想象,展现出它们超乎寻常的功能。几十年前,人们曾畅想“电话”能否没有电话线连接,随时随地就能打,现在无绳电话和手机已司空见惯了。录音电话、可视电话、密码电话等也相继问世。可见,科学幻想往往是科学发明的前兆,进行大胆、奇特地想象,对培养同学们的科学精神,大有益处。
