我喜欢跑步，因为我觉得这是一项有趣而又轻松的运动。我可以自己做。当我还是个小孩子的时候，我不是很健康。所以我父亲带我和他一起跑步。他说这对我有好处。起初，我一点也不喜欢它。但几周后，我跑步的时候感觉很好。因此，我每隔三打就跑一次。现在，我的一些同学和我一起跑。我们总是互相交谈。我这样的运动。

我喜欢很多种运动，比如游泳，跑步，乒乓球和羽毛球。但是我最喜欢的是跑步。跑步是人们保持身体健康和释放压力的运动。此外，我觉得跑步很容易。我可以在早上或课后进行跑步。我也可以一个人跑，不需要找伴一起跑。跑步过后，我总是感觉很好很放松。跑步已经成为我生活中的一部分。

今天，我和爸爸6点钟就起床跑步，屈指一算，我们已经跑了13天了。我记得第一次跑步时，虽然也跑了三圈，但跑完后感觉上气不接下气，简直要窒息了。那时跑得速度是先快后慢。

现在呢，我用稍快的速度持续跑了3圈，并且不感觉那么累了。我爸还说，坚持锻炼再熬夜就不感觉很累了，也能增加肺活量。我一定要坚持锻炼！

太好了!太好了!”今天又没有跑步，我们班大多数同学欢呼起来。可有少数同学却皱着眉头，表示出不高兴的样子来，我想：“他们一定很想跑步。”
跑步对于我来说又好又坏，怎么说呢?还是我给大家讲一讲吧!
同学们都知道我这个人怕累，因为我挺胖。每次跑完步我都觉得很累，腿也酸疼酸疼的，身子板也挺不起来。跑步对于我来说就是项艰巨的任务，好像总也脱不掉似的，真是没办法。
我回到家对妈妈说了这件事。可妈妈笑眯眯的对我说：“跑步是一项很好的有氧运动，可以减肥，增强体质，还可以提高你跑步的速度，但是跑步也不能过量地跑，跑多了对身体也会起反作用。”
我回到房间里想，妈妈说的也对。体育节的迎面接赛也跑完了，我真恨我自己跑得太慢没有能参加。
现在我也有点喜欢跑步了，可跑步能不能减肥，我还是多少有点疑问。
我爱跑步，这是我的爱好，也是我最喜欢的运动。
Iloverunning.It'smyhobbyandmyfavoritesport.
我喜欢在早晨的时候，呼吸着新鲜的空气，沿着小路慢跑，小鸟在树上叽叽喳喳的向我问好。跑累了，就躺在草地上看白云，一会儿变成威猛的龙，一会儿变成奔跑的马，过了一会儿又变成了一只可爱的兔子。我更喜欢在操场上与同学赛跑，风儿迎面吹来，仿佛在耳边唱起了加油歌，让我更加兴奋，不断向前冲！

跑步不仅让人锻炼身体，而且能够磨炼人的意志和毅力，让人觉得它很有趣。我爱跑步。

跑步是一项很好的有氧运动。它适合任何人。但是记得太累的时候不要跑步。吃太饱了不要跑步。不要跑太长时间。你跑步时要穿舒适的鞋子和衣服。跑步前多喝点水,跑步后不要立刻喝水。
跑步对我来说是一件容易的事。它已经成为我生活中的一部分。现在让我们跑步吧!
