Now I am in winter holiday, I am so happy, I can have fun with my friends. My friends and I make the deal that when the wind comes, we will go to the park and fly kites. Today the wind finally comes, after finishing breakfast, I go the park with my friends. We take out our kites, mine are butterfly, my friends are birds, all are so funny. I start to let my kite fly, but it could not, so I run faster and faster, then my kite flies, I go let go it gradually. A few minutes later, my friends’ kites are also flying. Seeing our kites flying, I feel so free. Today, I have a great time.
现在我已经放寒假了,我很开心,可以和朋友们玩。朋友们和我约定风来了,我们就去公园放风筝。今天风终于来了,早饭过后,我和朋友们去公园。我们拿出自己的风筝,我的.是蝴蝶样,朋友的是鸟的样子,都很有趣。我开始让风筝飞,但是飞不起来,因此我跑得越来越快,风筝终于飞起来了,我慢慢放飞。不一会儿,朋友们的风筝也飞起来了。看到我们的风筝飞着,我觉得很自由。今天,我玩得很开心。
很久很久以前,在北方的地方有敌人来侵略时,没有手机和电话,古人就用狼粪晒干后烧了就会有一股浓烟直冲云宵做警报,总兵看见了就会派兵支援。如果有信就用骑马送信,如果要把信送到国外的话,还要走水路而且要走好几个月呢!正因为这样所以人们发明了鸽子送信,非常方便,缺点是鸽子在半路有可能会被打下来,或被敌人发现抓了去。
随着科学的进步人们又发明了无线电通话器,慢慢的又有了电话和手机,虽然很方便,但随着社会的进步人们又发明了电脑和网络,不仅可以当通讯用而且还可以查资料,非常的方便快捷。听老爸说,以后打仗的话也都只要用电脑来打了。虽然我还是不太明白老爸的话,但我相信随着科学的进步这是完全有可能的。
我觉得世界的变化真大啊,我能生活在这个进步又发达的社会中真的很幸福也很幸运!
