今天下午刘浩轩的妈妈到我们的教室讲课,而阿姨的主题是我感兴趣的“无人机”,她还带来了一架小型的无人机。
这架无人机“长”着八个旋翼,每个旋翼上都有一个小型螺旋桨和一个陀螺仪。下面还有两个可以接电池的线和一个可以充电的线。无人机有一些优点和缺点,它的优点是:就算无人机爆炸了我方也不会有人员伤亡;它就算跟敌军同归于尽我方的损失也能降到最低。而它的缺点则是:一旦没电机体就可能坠毁;如果信号被屏蔽那么飞机就完全不起作用了;而且它只可以装两个导弹。所以我想将来要制造使用时间更长的电池和无法被屏蔽的信号。我以后还想要发明可以装十个导弹的无人机。
今天我终于认识了无人机,还知道了一些关于无人机的知识。我长大以后要创造更先进的`设备,为人类做出贡献。

第一种:直接反驳。抓住错误论点的要害,分析它的谬误,或者分析错误论点的危害性,用它已经造成或可能造成的后果,揭示它的谬误。
第二种:间接反驳。提出一个与错误论点截然相反的新论点,并对此作充分论证。正确论点一经成立,也就驳倒了错误论点。
第三种:归谬反驳。针对错误论点的破绽,先故意假设其是正确的,然后依此进行合乎逻辑的推理,得出一个十分明显的荒谬结论,从而证明错误论点的荒唐可笑。
上周,张叔叔送给了我一架小型无人机。我心里乐滋滋的,像一股清凉的泉水在我心中流过。
在此之前, 我一直不知道无人机长什么样,今天可总算见识到了。
它长约30厘米,宽约20厘米。这个家伙"长"着四个旋翼 ,每个旋翼上都有一个小型螺旋桨.下面还有可以充电的线。它是通过遥控器来指挥的。并且,机身上还可以挂摄像机进行航拍。酷毙了!
接着,在没有看懂说明书的情况下,我便进行了试飞。结果,我眼睁睁的看着飞机愈飞愈高,并伴随着前进和嗡嗡的声音,很快就使我心生惧意。便不再操控它。突然飞机像失翼的鸟儿一样急速下坠,啪的一声栽倒了墙边。
看样子得找一个空旷的地带,于是我和爸妈每晚都去体育场试飞。过程中不断有人问我的飞机,我的感觉那就像晴天一样,灿烂无比。
这么多天以来,我都没有控制好它的操纵,只能让它平稳着陆。不过白玉曾说过:万事开头难、仲由也说过:欲速则不达。
在众多的玩具中,我唯独对它情有独钟。我非常感谢叔叔给我买了这个玩具。
