Study is our student's personality.But many students will ask, why we must learn knowledge. Is knowledge so important to us?If we don't need to pass the exam, should we still need the knowledge?
As I am concerned, study is not only a personality of students, but also a personality of all people throughout their lives.People need to learn the knowledge whoever they are.If people don't learn knowledge, there will have no way to do things and become ignorant about world.Can you imagine a world that no people have knowledge?Leaving knowledge,the world would no get progress.If people don't learn knowledge, there will be no people to know how to use the computer ,how to write the news, even how to communicate with others.
So learning knowledge is a very important thing, it consists of our world.
Long, long ago, there were two brothers, the one rich and the other poor. When Christmas Eve came, the poor one had not a bite in the house, either of meat or bread; so he went to his brother, and begged him, in God's name, to give him something for Christmas Day. It was by no means the first time that the brother had been forced to give something to him, and he was not better pleased at being asked now than he generally was.
"If you will do what I ask you, you shall have a whole ham," said he. The poor one immediately thanked him, and promised this.
"Well, here is the ham, and now you must go straight to Dead Man's Hall," said the rich brother, throwing the ham to him.
"Well, I will do what I have promised," said the other, and he took the ham and set off. He went on and on for the livelong day, and at nightfall he came to a place where there was a bright light.
"I have no doubt this is the place," thought the man with the ham.
An old man with a long white beard was standing in the outhouse, chopping Yule logs.
"Good-evening," said the man with the ham.
"Good-evening to you. Where are you going at this late hour?" said the man.
"I am going to Dead Man's Hall, if only I am on the right track," answered the poor man.
"Oh! yes, you are right enough, for it is here," said the old man. "When you get inside they will all want to buy your ham, for they don't get much meat to eat there; but you must not sell it unless you can get the hand-mill which stands behind the door for it. When you come out again I will teach you how to stop the hand-mill, which is useful for almost everything."
So the man with the ham thanked the other for his good advice, and rapped at the door.
我国劳动人民很早以前就对太阳活动进行了研究,积累的丰富的科学资料。随着人们对太阳天体认识的深入,对于太阳辐射能的利用也越来越广泛。例如:利用太阳辐射的光化效应,可以加强对植物的光合作用,利用太阳辐射能转变为热能,人们制造了太阳灶。又如,人造卫星上的太阳能电池,可以将太阳辐射能变为卫星中仪器工作所需要的电能,等等。太阳辐射能量在地球面上的分布,是影响各种天气变化的重要因素之一,并引起了各地气侯的许多差异。因此,观测太阳辐射是气象工作者研究的重要课题。
由于太阳辐射到达地球表面以前,中途经过大气层中的臭氧、二氧化碳、水汽、尘埃等物质的吸收或散射,能量会有所减弱。因此,地球上不同的地区和时间所得到的太阳辐射量,其大小不仅与地球表面所产生的高度角有关,而且与大气层的厚度、混浊度和水汽含量有密切关系。太阳的'高度角,就是太阳照射地面的入射角。太阳光照射越接近直射,高度角越大,相应的穿过的大气层薄些,到达地面的太阳辐射量就大;越是斜射,高度角越小,相应的穿过的大气层就厚了,到达地面的太阳辐射量就小。另外,由于地球表面的地形高度不同,得到的太阳辐射量也会不同,越高处大气层密度越小,纯洁度也越高,因此的行高的地面,获得的太阳辐射量,就比地形低的地面获得的要大。
由于地球大气的影响,在地面上是很难测出太阳真正的辐射量的。而世界的最高峰――珠穆朗玛峰,是地球表面的最高处,太阳辐射到达那里所要穿过的大气层比别处要薄,同时那里的大气比较纯洁,透明度大,太阳辐射所受到的影响小,是探讨太阳辐射的一个理想的场所,更能反映出太阳辐射的真实面貌。我国科学工作者先后在珠穆朗玛峰海拔5900米、6500米和7000米以上的地方,设立了许多观测点,对太阳辐射和高山气象进行了观测,取得了世界上地表面最高点的太阳辐射观测数据。这不仅对发展工业和建设国防具有重要意义,而且,把帝国主义在1965年从珠穆朗玛峰南坡所窃取的有关资料,远远的抛到后头。
在黑暗中曲折前行,不畏艰苦,心要在焉。
是什么让韩信屈于胯下之辱,只为日后一次搏击?是什么让勾践卧薪尝胆,忍辱负重东山再起?是什么让布鲁诺不惧命运的火舌,高颂科学的`赞歌?是那为信念献身的灵魂,穿过昏黑的洞穴,在世界英雄之林大放光华。他们心无旁骛,只为一抷精神的乐土。“一切愿望的本质享乐乃是精神之悦。”那不只是罗素——人的呐喊,那是无数虔诚心灵的颂歌。曝霜露何妨,遍地棘草又何惧?心在焉,黑暗终成光明。
在名利中目不斜视,不屈诱惑,心要在焉。
“真正的光明,不是没有被黑暗浸染,而是无法被黑暗掩盖自身的光辉,真正的英雄,不是对世俗避而远之,而是在世俗中坚守自我”,罗曼·罗兰的话仿佛一记醒目,震撼了无数心灵。英雄就如刘备,受人景仰却为那圣洁的家园甘于落魄;英雄如李斯,身处宦海却抓住信仰的浮木,自主沉浮;英雄当如拿破仑,没有沉迷于甘醇美酒,只为法兰西燃尽生命之灯。名利诱惑如毒药,若非心在焉,只能被它腐蚀心骨,碌碌一生。
在变迁中坚守自我,不随流波,心要在焉。
李斯特大概是命运之神的宠儿,天赋极高的他年纪轻轻就在维也纳书写传奇。但他并没有因际遇改变而放弃心底对音乐的热忱。卢梭守着一份愧疚度过一生,《忏悔录》中的只言片语,诉说着他未随岁月涤荡而褪色的真诚。安德鲁·马修斯的《感恩的心》不正是他人生中不变情怀的最好写照吗?心在焉,犹如一盏耀眼明灯,指引未来的路。
花儿愿为一只鸟,鸟儿愿为一朵云,而它们不变的是对生的热爱和追求。心在焉,不论在宦场,在野林,心怀未来便有了舟。心在焉,我们终能踏上命运的圣殿,满身花雨又归来。
Why students can't help wearing expensive things which are famous brands?
The reason why they prefer to wear expensive clothes is just for face. Some students thought the more expensive they wear, the more confident they are. Only wearing brand clothes can they become proud. Some students are afraid to looked down if they don't wear brands things. It is easy for students to compare what they wear.
As far as I am concerned, I don't agree that students pursue famous brand. Most students can't earn money by themselves. We can't waste the money to buy expensive things which are not useful. It is hard for parents to make money. Remember, the main task of the students is to study.
