我要去发明一些专门克隆生物的机器。我想那时如果发生了无情的战争或发生恐怖袭击的话，可以让许多克隆人上战场，这样就可以减少战斗人员的伤亡和经济大量的损失。将来如果地球上的水资源被大片地污染，纯净的水源就会大量地极速减少，那时，我们就可以动用高科技克隆机器，将那些仅存的纯净的水大量地克隆起来，我们也就不会担心纯净水不够喝的问题了。将来，我们的氧气也有可能会大量地减少。那时候，我们也可以去用空气克隆机器去克隆氧气，这样，我们就可以尽情地去呼吸新鲜空气了。那些克隆机器不仅可以去战场打仗，也可以去忙于建设国家，也可以去忙于救灾。但我最希望的是能够用克隆机器去克隆一个地球出来。现在人口繁多，还在不断繁衍，以后地球可能会承受不了这么多的人口，所以我们可以移一些人民居住到另一个地球上去，这样就能解决人口繁多的问题。

我还想发明一些太阳能的器具。大家都知道现在有许多太阳能器具供我们使用，可是还远远不够，还需要更多一些。我们现在的环境已经够污染重的了，造成这样的环境现状，汽车排放尾气，是有一定责任的。所以我最先要发明的就是太阳能汽车。这种太阳能汽车除了不排放尾气外，其他均与普通汽车一样。这种太阳能汽车晴天不仅可以吸收太阳能，还能够去储存大量太阳能，以便给汽车夜间使用。这种太阳能汽车还能有一个备用太阳能核，如果太阳能用完时，备用太阳能核会自动打开提供太阳能以驱使汽车前进，等有太阳时，备用太阳能核有会去收集足够太阳能，以备日后使用。

我还想去发明能够提高宇宙飞船速度的工具。现在我们人类对宇宙的认识实在太少了。我可以去发明一些能够提高宇宙飞船速度的工具，好加快人类去探索宇宙的速度，能够去到各个星球上去探索资源，也可以让人类去到银河系外的宇宙，去探索更多奥秘。

我想要当一名伟大的科学家，去发明各种各样的工具，去发现更多的资源，去更好地造福于人类。

我想做一名科学家山不在高，有仙则名；水不在深，有龙则灵；人不在贫贱，有梦就能赢。每一个平凡的人都有自己远大的梦想，只要你朝着自己的梦想而努力，就能实现自己的梦想。

我有一个梦想，深深扎根于我的心中。那就是长大后，我要成为一个科学家。因为我相信，只有经历地狱般的磨练，才能练出创造天堂的力量；只有流过血的手指，才能弹出世间的绝唱；只有经历困难和挫折，才能实现自己的梦想。以前，每当我看到科学家们令人瞩目的成就时，总会感到羡慕和敬佩。是他们，推动了社会的发展；是他们，使人民生活水平得到提高；更是他们，为祖国的发展赢来了一个崭新的明天。

因此，我想成为一个科学家，成为一个对国家有贡献的人，成为这个国家的栋梁。每当我看到浪费时间的人时，我会为他们感到惋惜；每当我看到灰心丧气的人时，会为他们感到悲哀；每当我看到不务正业的人时，我会感到愤恨。因为他们没有看到自己的.价值，没有属于自己的梦想。这样的人生，是没有意义的人生。而我，至少有一个梦想，一个目标。有了这个梦想，我就会一直努力下去，永不放弃。有了这个梦想，就等于把握了自己的人生航向，不会再迷失方向。有了这个梦想，就好象一盏明灯，照亮了我前进的道路。一直通往胜利的顶峰。

为了这个梦想，我会努力奋斗。也希望人人能向着自己的梦想奋进，寻找属于自己的明天。
