资源描述

1、1尾巴作用大清晨,太阳刚刚升起,鹿妈妈带着小鹿走出森林,来到河边喝水。清清的河水映出了小鹿的身影。小鹿走进水里,望着水中自己的影子,对妈妈说:“妈妈,动物有嘴能喝水,有眼能看东西,可是,长个尾巴干什么用呢?”妈妈指着河里一条正在游泳的小鱼,问小鹿:“你说说,这条小鱼靠着什么往前游?”小鹿看了看,对妈妈说:“靠尾巴左右不停地摆动呀!”妈妈点点头,又指着天空一只正在飞翔的小鸟,问小鹿:“这只小鸟飞的时候,为什么能拐弯呢?”小鹿仔细看了一会,回答说:“靠转动他的尾巴呀!”妈妈点点头,又指着草地上一匹正在吃草的马,问小鹿:“那匹马为什么不停地甩尾巴?”小鹿忙说:“我知道,他用尾巴赶蚊蝇啊!”妈妈说:“

2、是呀!这又是尾巴的一种用途。你再想想,森林里的松鼠,在树上跳来跳去,为什么摔不下来?”小鹿摇摇头说:“我不知道。 ”妈妈告诉他:“松鼠是靠尾巴平衡身体,才摔不下来的,这也是尾巴的一种用途。 ”小鹿正认真地听着,突然妈妈大声喊他:“快走!鳄鱼来了。 ”只见一条大鳄鱼,从不远的水里,正偷偷地向他们游来。小鹿赶快从水里跳出去,跟着妈妈跑到草地上。妈妈对小鹿说:“以后再到河边喝水,可要注意鳄鱼,他会偷偷游到你身边,突然用尾巴一扫,把你打到在河里,然后把你吃掉。 ”小鹿说:“原来尾巴是鳄鱼进攻猎物的武器呀!”小鹿又问妈妈, “我的尾巴有什么用途呢?”妈妈说:“咱们的短尾巴,用途可大了,遇到豺狼虎豹袭击,咱们在逃跑的时候,短尾巴就会一次一次往上翻,露出尾巴里面的白颜色,这样,尾巴就成了引路的标志,一只跟着一只都不乱跑、不掉队,敌人就抓不着咱们啦。 ”小鹿哈哈笑了:“没想到咱们的尾巴,有这么大的用途。 ”妈妈问小鹿:“我讲了这么多,你能记住吗?”2小鹿说:我全记住了,您听我说一遍:动物尾巴用途多,我给妈妈说一说。鱼儿尾巴管游泳,松鼠尾巴管平衡。鸟儿尾巴掌方向,马的尾巴赶蚊蝇。
