我把鸡蛋放到桌子上,妈妈先把放在碗里的鸡蛋给我剥,我在桌子上磕了一下,然后很高兴的剥起来。可是却很难剥,而且剥掉的.鸡蛋壳里还带有很多白色的蛋白。妈妈又把在冷水里泡过的鸡蛋给我剥,我三下两下就剥好了,而且剥好的鸡蛋表面光滑雪白,我对妈妈说:“这个鸡蛋真好剥,为什么呀?”妈妈说:“你先想想看,我们平时烧开水时,如果把水壶灌的太满,水开了以后会怎样?”我说:“水当然就会冒出来。”妈妈夸奖我说:“真聪明!回答正确!”“想知道为什么吗?”妈妈逗我说。我点头表示同意。
妈妈告诉我:“因为水受热后,体积变大,所以就冒出来了。很多物体受热后体积都会增大,而受冷后体积就会缩小,这就叫热胀冷缩。热的鸡蛋放到冷水里,蛋壳和蛋白都要收缩,但蛋白比蛋壳收缩得要厉害些,这样,蛋壳和蛋白就离开了,所以剥皮就很容易了,就不会占掉蛋白了。
我终于明白了其中的道理,热胀冷缩的原理还真神奇呀!
这天晚上小$和小#都没睡着,半夜十二点刚过,隐约的哭声又飘来了,“咿咿——呀呀——”,令人寒毛倒竖。小$对小#说:“我们去找找吧。”便拉着小#寻声走去。小#早已面如纸色,木木的.由小$牵着走。深夜的宿舍走廊弥漫着鬼魅的气息,几盏忽明忽暗的小灯照着,把她们的身影长长的拖在地上。她们巡着这哭声来到了四楼。这层楼面几乎所有的房间都关着。在这里哭声听起来更凄惨,更恐怖。现在连小$也有点害怕了。她们来到一间寝室门前,这里就是传出哭声的地方。这间寝室显然已空关了很久,门上斑驳的旧漆和一些蜘蛛网表明这里好多年没人料理了。
这时恐怖的哭声突然停止了,留下死一般的寂静。小$定了定神,看了一眼发抖的小#,然后用力推门,但是门锁得死死的,根本推不开。小#颤抖的说:“我--我们回去吧,我好--好怕!”小$根本不听,她发现这扇门的锁是老式的,有一个小指指甲般大小的钥匙孔。于是她就把眼睛对着钥匙孔朝里看,只看到血红的一片,除此之外什么也没有。她揉了揉眼睛再朝孔里看去,依旧是一片血一样的红色。她喃喃的说:“怎么尽是一片红色呢?”
听到这话的小#一下子瘫倒在地上,发青的嘴唇颤抖的说:“学姐说,那女生吊死的时候——眼睛被血染红了——小$,她的眼珠是红色的!!
在我才上一二年级时,我就开始学着将空荡荡的茶瓶提到不远的打水处打水,可那是毕竟小,多少还是有些吃不消。可不,一次身体本来就不太好,加上我家住在五楼,提着沉重的茶瓶才刚过一楼,因为太累,茶瓶就掉在了地上。还好,开水没有溅到太多地方,只有手上有些。父母闻声赶来,要是平时他们早就会说我一顿,可今天却好像料到了会这样,啥也不说,只有母亲小声嘀咕了一句“毛毛不像以前一样了。”
我很好奇:“我以前咋了?”
母亲笑了笑,扶我到楼才说。
原来,在我才一岁左右,刚学会走路没几天的时候,我对周围的`一切都感到新奇,以前只能乖乖躺在母亲怀里,哪儿都不能去,有时悄悄开溜儿爬走就会被母亲逮到。现在会走路了,就跌跌拌拌来到了茶瓶面前,以前经常看到父母用这个东西往另一个东西里倒什么,他们还喂给我喝。所以,我决定弄明白些什么。可就在这时,父亲就会把我抱走,不让我碰。
可我哪儿能听,一找到空子就跑到茶瓶前仔细琢磨,可他们总是把我抱走了。一次,父亲终于有点儿恼了,他想出了一奇招。一次,他故意帮我把茶瓶盖拿走,母亲却想将我抱走。可父亲说“让个他尝尝什么是疼,他才会不敢。”母亲听了,只做叹气。我也不懂,望着从茶瓶中升起的缕缕白烟,以为里面有些什么,就大胆的将手指伸了进去,幸好父亲有准备,瓶里的水不多,瓶口小,我一不小心碰到了边缘,疼得我“嗷嗷”直叫,实在是太烫了,我看了看手,红扑扑的,似乎是肿了,我一下子就哭了出来。父亲知道有效果了,赶紧连哄带骗弄好我。从此,我一件了那东西就跑。母亲不太高兴,说这样长大怎么办,父亲倒不建议“不让他知道什么叫疼,他以后哪儿晓得什么事该做,什么事不该做呀!放心,长大了就忘了。”
说到这,母亲停了停:“你呀,长大了,是该懂了。”
是呀,大了,该懂了……
童年,让人成长的童年。
Nowadays, advertisements can be found everywhere in big cities. They shout at us from the television screen and radio loudspeakers, wave to us from every page of the newspaper, signal to us from the roadside billboards all day and flash messages to us in colored lights all night.
Faced with a flood of advertisement, some people wonder whether it is necessary to have such huge sums spent on advertising. They often cite in illustration of it the attractive, but false and deceptive advertisements to which many consumers fall victim. Why don't we stop advertising and use the money to reduce the price of goods? It sounds like a good idea, but they fail to notice the contribution advertising makes to our society. Because the production of a better product to compete for customers' money is the goal of advertisers, customers are thus given a chance to compare their products and get the best and cheapest one. Besides, as the advertisement can provide people with a lot of immediate and detailed information as to the availability of a certain product, or a service or a job, it makes life much more convenient. And another thing we mustn't forget: the fact that we pay so little for our daily newspapers and TV programs is due entirely to the money spent by advertisers.
Advertising performs such a useful service to our society that we can't imagine what would happen if there were no advertisements. (198 words
