童年像一扇窗户,你打开了这扇窗户,就会发现童年有很多美好的回忆。 童年中的趣事是最珍贵的。小时候,我们因为幼小无知而闹出了许多笑话,打开记忆的匣门,童年趣事便接踵而来。我5岁那年,还在幼儿园里上学,年少无知的我为记忆的宝库里增添了一些耀眼的色彩。
又是一年的夏天,我感冒在家,爸爸、妈妈都去上班了。我闲得无聊,在家里东转转、西逛逛,走到鱼缸前,我喂了一些鱼食,平时最爱吃鱼食的小鱼们都沉在水底,不肯浮上来吃食。莫非它们也感冒了,我想这可不行,异想天开的我,立即拿出一包抗病毒冲剂,把里面的药颗粒全都倒了进去,只见小鱼们全浮上来,大口大口吐着泡泡,我还以为它们在吃药呢,见小鱼们“吃”了我十分高兴,于是我就回屋去看电视了,也没在意小鱼的死活。我看电视正看得来劲,也没注意爸爸下班回来了。突然屋外一声呵斥:“鱼怎么都快要死了!虎子!你在鱼缸里放了什么?”我赶快跑到客厅,只见爸爸指着鱼缸问我。我一头雾水便把事情的经过告诉了爸爸,爸爸一听却笑了起来,而当时的我,这个当事人还在发愣不知道怎么回事。 ……
许多童年趣事直到现在都令我记忆犹新,有的事我现在回想起来还会大笑。当然我也明白了我现在长大了一定要明辨是非,在做事前先想一想,做到“三思而后行”!
马歇尔把牛顿力学的均衡概念应用到经济学中提出了“均衡价格论”,不得不说这是伟大的创举,这也为经济学借鉴其它学科的方法开创了先河。马歇尔的在《经济学原理》中确立了均衡概念在经济学分析中的核心地位,这就等于确立了价格机制在经济运行与资源配置中的中心地位,即价格的变动反映了商品稀缺程度的变化,并进一步调节着供求水平使其最终达到平衡。那么什么是均衡价格呢?马歇尔认为,商品的供给与需求处于均衡状态时所形成的价格就是均衡价格,它是由需求曲线和供给需求直接决定的,其交叉点的价格就是均衡价格。但是马歇尔的均衡价格论并不仅仅局限于供求决定论。马歇尔认为,价格与供求是相互作用的连锁反映,价格会影响供求,供求也会影响价格。他的论证是这样的:假设价格水平一定,如果需求大于供给,价格会上升到当前价格以上,生产也会随之增加。与此相反,假如需求小于供给,那么价格就要下降到当前价格一下,生产也会因之减少。马歇尔在《经济学原理》中从这种相互关系出发,分析了供
给、需求和价格的函数关系。《经济学原理》强调的是均衡价格的形成,马歇尔用坐标轴的方式表现了均衡价格,即某种商品的供给曲线和需求曲线的相交之点就是该商品的均衡价格(纵坐标表示)与均衡产销量(横坐标表示),这个产量点表示均衡价格下生产者愿意供应的数量恰好等于消费者愿意买进的数量。
Elephants are the biggest wild animals in land, in the world. But now, they are also in danger. Let me tell something to you about them.
Elephants are big and strong and they are grey. They have long trunks and tusks, so they look a little dangerous. But in fact, they’re friendly towards each other and hardly hunt people.
Elephants have ears like fans, they make them look bigger and bigger.
They live in a group together for many years, they’re a big family. They also have good hearing and good sense of smell. Elephants can do lots of things if people train them. For example, they can carry heavy things, can do as a vehicle, ext.
Badly, it’s difficult for elephants to survive in the world usually because of people. If people sell tusks, they will make lots of money.
So, many people kill elephants for their tusks. Living areas are also an important reason of the die out of elephants.
Animals are our friends, we should protect them, or the number of wild animals will getting smaller and smaller.
Children's finally here, it is our holiday, but imagine the children also accompanied by together, everybody is more excited.
Children on this day, white clouds float over the blue sky, the children also have made a hot air balloon, they sit together on yourself a hot-air balloon, extremely happy! Balloon flying high, and finally flew to the sky, the children are in the sky holiday, the children sit on clouds, umpa jump, like a frisky little monkey.
Playing children, suddenly to rain cats and dogs, the children of the balloon has stalled, baiyun sister swept away by the wind, the children fell into despair. Is a time of crisis, a group of dragonflies sister and sister flew caught the children, and the safety of the children to the ground.
On the ground, only butterflies woven into a rainbow "lei", the children wear a wreath, some like a fairy, some like a warrior.
Play tired, the children fell asleep between full of fragrance of flowers.
Children's good play my imagination, to one day be able to live in such a children's day.
