答案很明确:不是。为什么呢?衣服有什么用呢?我上网搜索了一下得出了答案:
人是炉子!我们已经知道我们吃下去的食物——这就是劈柴,它在我们的身体里燃烧。这时候什么火花也没有看见,我们说它在燃烧,只是因为我们身体里感觉到热。
主要观点:人吃下去的食物,会在体内被人体消化吸收,给人体提供热量,因此每时每刻人体都在产生热量。
但为什么穿上衣服才感到温暖呢?
人是恒温动物,每时每刻都在散发热量,然后热量进入衣服和体表间的空气层,而衣服保证了带有热量的空气不流失,从而保证了体表的温度。
高温物体会向低温物体传递热量,温度差越大传递越快。当身体温度高于外界空气温度时自然会向空气传递热量当然穿衣服也会向衣服传递热量,不同的是空气是流动的它会不停的从你身上吸走热量,当你穿上衣服后你的身体会传递热量给衣服衣服上的温度就会上升,温差减小传递速度也就会减慢这样人就会感到温暖。也就是说我们筑了厚厚的墙壁,冬天还安上双重的窗,还在门上包上毡。我们穿衣服也正是同样的`原因。不让我们身体的热量散失到室内的空气里或者到街上去,我们使衣服暖和,它把我们的热量保持在我们身体周圄。我们的衣服当然也要向外散热,可是比我们身体散热慢得多。
主要观点:身体本身散发热量,而衣服可以来保存这些热量让人觉得温暖。
说白了,衣服就是一堵墙,在我们冷了的时候帮我们“遮风挡雨”,让我们温暖。
To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界,
一花一天堂,
手中即无限,
永恒亦短暂。

我很好奇,你是不是已经成为了一位足球明星?因为我现在的梦想里有一项,那就是也要成为一名足球健将。我虽然做其它事有点笨手笨脚,但玩足球毫不含糊。希望你是梅西、罗纳尔多和小罗纳尔多合体的“加强版”,代表中国队出征,踢出中国足球的威风。如果确实是这样的话,那现在的我,就提前为你感到骄傲和自豪。
我还非常想知道你有多帅,多高。现在的我,自我感觉还算是一位很帅气的小男孩——虽然有些瘦弱,像豆芽菜似的。我决心坚持体育锻炼,让自己变得壮实一些,成为一个阳光、健美的男子汉。
你也许是一位经营有道、富可敌国的老板,或是一位著作等身、名满天下的作家,又或许是一名知识渊博、桃李满天下的老师,还有可能是叱咤风云的赛车手……这些都可以,只要你拥有自强不息的精神,用心去奋斗,人生就会步步走向辉煌。
你有没有一位聪慧贤淑的.好妻子呢?有没有一个淘气顽皮又天真烂漫、活泼可爱的孩子呢?写到这里,我都有点不好意思了。看来,我真的要努力才行,为你打下扎实的基础,好让你更好地为人夫,为人父。

看见他,我总是畏惧,不是一种做了亏心事之后的后怕,而是一种来自心底深处的震撼与敬佩,因为他拥有神奇的魔力。
小时侯,我不肯去幼儿园,他仿佛有一种专门为我设计的魔咒,让我乖乖上学的魔咒,持续到今。
他是个极其稳重的男人。开车时,随机应变,以安全第一,速度拿捏得当。妈妈在后座却总是一个劲地唠叨:“你啊是要去投胎啊!开那么快。”我扑哧笑了出来。他从后视镜看向妈妈,一本正经地说:“坐你老公的车还不放心吗,你永远是安全的。”妈妈便像喝了蜂蜜一般,甜甜地笑了,风抚过她的发际。啊,他是对妈妈施了什么定心魔法了吧。妈妈安心地坐在后座,夕阳的余辉爬进车窗。
这个男人在稳重中还夹杂了一点点放纵。走在公园的小路上,月光倾泻,他的头发被镀上了一层层光泽,与湖面相映,岸边的月季花倾吐淡淡的香,陶醉了月色。他突然回过头来:“女儿,和我比比跑步。”沉浸在失利的悲伤中,我无力地摇头。“为什么,不是你老说你跑步很厉害吗?比比,快点快点。”我无奈,感觉不和他比跑步我就像欺负了一个小弟弟一样。他飞也似地冲了出去,我也飞快地追了上去,心情在不知不觉中明朗起来,我看见湖面微波荡漾。啊,他又对我施了什么魔咒,使我的心情舒畅起来。真是个狡猾的男人!
其实,很早很早以前,他是个十分厉害的魔法师,拥有各种法力。他会突然变出一个巨大的毛绒玩具,只为博得女儿一笑;他会突然使菜肴变得好吃起来,只为看见女儿狼吞虎咽;他会突然出现在我面前,只为看见女儿惊讶的表情;他会让坏了已久的房灯在某天突然亮起来,只为可以让女儿更好地学习……还有好多好多。
然而,岁月并没有眷恋他。他轻轻叹着气收起他的魔法袍,对我说爸爸不再年轻了啊。真的,我眼睁睁地看着他在我身边一点点老去,一点点失去青春活力……
突然好想说一句话,爸爸,在女儿眼里,你一直都是一位让我敬佩的魔法师,你永远是最顶尖的魔法师,而且威力无边。
