2007/9/30 人病志不衰
是周病,症诊为感冒之毒,余始轻之,未料愈笃,旦夕疾甚,造名医之不能是故且求于药。其类不丰,唯板蓝根与消炎药者也,效微而值甚,堪堪缓一时耳,徒显上之无道也。斯病如是,猛于野兽,为凡人所不能当者。 本周感冒,感觉不太好,主要是咳嗽受不了,晚上都睡不好,并且因为我传染给了一大片人,罪过,罪过。 这周算是调整周,对各学科进行了一次调整,效果不错。因为生病的原因,状态确实比较差,所以考试成绩不咋地,但是还是可以从一些细节处发现自己的进步。数学上似乎找到了点高考的感觉,错误率开始下降(比较明显),偶尔也能在几道题目上想出点出彩的方法(不过我们老师备课资料的解法实在太多……总是能被他找到一些漂亮的解法,幸好大部分我都想到了),看来若是以我现在的状态回到过去搞搞数学竞赛也是有点希望的(哈,Kidding)。不过依旧有很多东西需要补,毕竟现在周围的都不是精英了,长期处在这样的环境下或许会让我懈怠,嗯,一定不能松懈啊,我还差得远呢。 语文的话越来越有感觉了,真的觉得以前高中的自己怎么这么弱,连语文都搞不定。反正现在的语文已经不再是羚羊挂角,无迹可寻了。 英语上我付出的努力也渐渐有了回报。懂的越来越多,语感一点点好起来,词汇量也慢慢加大,势头很好。 关于物理,也就这样吧,不过要说到曹XX那个家伙,上课时好几次提“张大同”怎么样怎么样(意思就是不如他),摆明了挑衅我。然后有一道题目关于浮力的他讲了个解法我觉得不对,找他详细问一下,结果他就搪塞我,然后我证明了他错的要找他理论,他甩都不甩我,看到一本王后雄高考什么什么的书上面有这题就说书上有的你自己看,肯定是你错了。我一看那书完全是扯淡,关键的细节根本没有证明。真是岂有此理。 此处附题,有兴趣者看看到底是他错还是我错: 题目就是一秤上放一水箱,水箱里有一木球被一绳系在箱底故完全被水浸没。问绳突然断后秤示数如何变化? 曹XX答案:变小,因为绳子断后,木球加速上升,对应等效有一水球加速下降,又木球对水(也就是对秤)作用为浮力并没有改变,而那个水球却因为加速下降而失重,故水箱中一部分水失重,所以显然秤的示数变小。 看上去很有道理,但是那个“对应水球下降”原来是用于匀速的,现在是加速,是否等价可以用没有论证。 我的答案:变大,因为绳子断后,木球加速上升,木球对水作用没有改变,对应有一水球加速下降,的确失重,但是那个水球和周围水的作用方式是依靠浮力,而这个浮力和木球一样是不变的,所以在秤的示数上不会体现出来。而箱底少了个绳子拉力,所以变大。 第二个证明:取水面高度看,绳断后,水面高度不变,而绝大部分液体处于静止(超流体),那么水箱底部液体压强不变,所以水箱底部受到水压不变,而缺少了绳子拉力,所以秤上示数变大。 第三个证明:(反证)若是曹某答案对,那么请问:当我一物体体积很大(远大于水的体积),密度只有水的一半,那么绳断时,按照曹的说法,对应物体体积的水将完全失重,于是秤示数将为负值?这怎么解释? 以上,关于此题不要用现实物理的角度去考虑,因为题中的所有涉及的理论及物体都是理想的,特别是关于水是理想液体,具有超流性。问题的关键就在于物体和水相互作用的方式理想化为仅有浮力,而浮力与物体的运动方式无关,于是这题就脱离了实际,应当以纯理论的方式去考虑。 虽然对自己的智力略提高了点信心,但是脱离精英的环境,远离高等的教育还是会有很多负面影响的。无论如何,我不能输,我也不会输。 关于学习就扯这些。
下面英语杂谈: As the time is passing, we classmates are getting more and more familiar. I can’t believe that even Restudiers are more blank than diligent. The leading actor of this week is so called “Prof. Li”. The reason why he is called such a name is the same meaning of the former “Dr. Z”(郑博士) or “Dr. J”(江博士)who spreads “the knowledge against health”. Prof. Li once said that he likes the girl sitting in the first seat of my row. And it is him that drove a storm of “pursuing beauties” of our class. On the other hand, he is the enemy of the Small Fattie, but that isn’t the point. What I want to say is, that, the storm might be bigger than I had thought. Actually, there are too many charming girl in the class so as to make them lose their mind. Though I always insist my point that it can never be too bad that there’re so many lovely girls, it’s the reality we have to face that study is much more important. Small episode: Prof. Li always boast that he was gifted of a sense of humor, however once he had tried to tell a joke to three dormitory, actually there were no one even show him a smile. I mean no one thought his speaking is funny. Only God knows how ridiculous can it be! According to the complicated circumstance, I find a conclusion that those men are no less WS than guys in SJTU. Or it may be the common nature of boy students of 80 to 90’s generation? It’s hard to believe that WS is a general existence, but the fact has shocked me a lot. Alas, Sigh, Life’s hard. We all get involved in the complex society. Hadn’t we found joy from the totally disgusting life, it would be a hell constantly thieveing our life. Too much for the boring case, I can hardly find more interesting things. My brain is filled with grammer and vocabulary and vector and inequation and Newton’s dynamic and multiple meanings of ancient chinese and so on. It may not be the time to stop, but I can’t write anything anymore. Keep Striving, Keep Believeing. That’s all.
英语扯不出来了,就打住吧。本周故事不是很精彩,请期待下一期。我还要加油! 湘北,加油! 引用通告此日志的引用通告 URL 是: http://superzgl.spaces.live.com/blog/cns!7719BE89E6BB8352!988.trak 引用此项的网络日志
