我们河北邢台过去被称为百泉之城，因为它遍地是泉。最集中的是西南郊百泉村一带，泉眼密布，河道纵横，土地全部自流灌溉，盛产水稻、鱼虾和芦苇，宛如江南水乡。城北的'达活泉公园，更是以其清冽的泉水和旖旎的风光吸引着游人。但是70年代以后，邢台的泉逐渐干涸，众多的河渠变成了干土沟，昔日的水稻田现在生长的是玉米、小麦，以泉水著称的达活泉公园也只能靠自来水维持它那浅浅的人工湖了。
原因──过量开采地下水。

??穷人》课文续写练习范文从此，桑娜的负担更重了，自己的五个孩子算勉强填饱肚子，又何况多了西蒙的两个小孩呢？
日子一天天过去了，桑娜日日夜夜在家里照顾孩子，打扫卫生……丈夫每天清晨都驾着小船去海上捕鱼。孩子的衣服不够穿，冬天脚都冻得青一块紫一块的，菜只有鱼，有时一天只吃两顿，最可怜的是有时只有一块黑面包。每次爸爸出海回来，孩子们都是最高兴的了，因为爸爸回来就会有鱼吃了，孩子们每天都盼着爸爸早点回来。
这几天海风非常大，爸爸每天去海上都打不到鱼，甚至差点连命都没了。孩子们只好每天都啃窝窝头，桑娜看着他们那么想吃东西，就把自己的那份分给孩子们，只好自己挨饿。
就这样，日子一天天过去了，到了孩子们该上学的年龄，都有七、八岁了，但由于营养不良，孩子们看上去很小，只有五、六岁。孩子们很懂事，虽然想读书，但他们知道家里条件不好，。桑娜知道了，就把捡来的废报纸用线穿起来，给孩子们订成一本书，孩子们看见了高兴的`都快发狂了，总算是有书看了！！
捕鱼今天是桑娜的生日，孩子们想给妈妈一个惊喜，于是和爸爸一去下海，真巧，捕到了5条又肥又大的鱼，晚上，一家人围着的小木桌高兴地边吃边聊……
对话练习作文300字【五】
你可曾见识过国际象棋大师下盲棋？
在普通人的理解中，往往会觉得这种令人不可思议的能力应该归因于大师们超凡的记忆力，因此他们才能够记住棋盘上每个棋子的位置。但研究显示，其实并非如此，大师只是记住了当时整个棋局，这种记忆是取决于背景的，也就是只针对于那些正常棋局中出现的棋子位置进行记忆，如果是记忆一个完全杂乱没有规律的棋盘的话，大师的能力并不比正常人强多少。这也是为什么当阿法狗拥有了模糊记忆能力以后能够战胜李世石的原因之一。
国际象棋大师们不会像新手那样对棋子位置进行照相式记忆而通常是记住一些攻击路线以及运子。当看到棋盘时，他们马上会做出预判，哪一方占优势，棋局会朝哪个方向发展，以及下一步或者更多步的招法是什么。同时也会把注意力集中在某些棋子上，并在心理上移动它们以想象这些下法怎样改变棋局。因此，他们只需要看一眼就能辨别出棋子之间的相互规律。科学家将这种相互规律称之为数据块，而每一个大师有将近5万个数据块，也就是说积累了5万个相关棋谱。这种数据块被《刻意练习》的作者称为——心理表征。心理表征可以使大师既可以着眼于全局来观察，同时也能在必要的时候将注意力集中在具体的走法上面，即可见森林，又可见树木。
心理表征，是一种大脑正在思考的某个物体某个观点，某个信息或者其他任何事物相对应的心理结构，或具体或抽象。心理表征越丰富，我们对这个事情的记忆力和理解力就更强。
比如说，提到“羊驼”的'时候，假如我们只认得“羊”和“驼”这两个汉字，并不知道具体是个什么东西，“羊驼”这两个字很快就会被遗忘。但是如果加以解释说“羊驼”就是“草泥马”，大家脑海里马上会浮现出这是一个什么样的动物，它是什么样子，它代表着什么意思。很快，“羊驼”这两个字就在我们记忆当中固定生根了。这就是心理表征的应用。
心理表征无疑会造就更优异的表现。因为对于很多一般人需要思考和技巧才能解决的难题或做出的高难度动作，我们可以下意识的从相关的心理表征中提取出短时记忆，从而进行瞬时反应。在学习相关知识或练习技巧时，如果已经有相应的心理表征的话，则不需要像一般人一样去苦苦学习、分析这些信息，而是可以快速地把这些新的信息容纳入自己的思维体系。
在国际象棋中建立这样的心理表征，最关键的并不是比赛，而是打谱。也就是说深入分析下过的棋局，深入分析每个棋子的位置以及下一步招法，分析完之后，再对比大师是怎么下的。如果错了，回头再想自己漏算了什么。这就是刻意练习，如果只把注意力集中在比赛上面的话，顶多算是有目的的练习，甚至可能是天真的练习。
同样的，在医学行为中建立心理表征，最关键的并不是临床操作那一点手上功夫，而是是深入的去分析临床上面我们碰到的病例和文献当中的经典病例。
也就是说不能仅仅是跟着老师诊断病人，下医嘱，观察病情变化，最关键的是要在上级医生之前进行独立查看和诊断。在病房接诊病患时，先不要看他门诊病历上的诊断，自己询问病史做体查了解相关辅助检查结果，自己进行诊断和鉴别诊断，列出治疗的方案、检查的重点和需要观察的问题，然后和上级医生的诊疗过程去对比，看他是怎样思考这个病例的。如果跟自己想的有不同的，可以查查文献或是以前的经典案例，看是谁的方案更有道理。最后去跟上级讨论，获得反馈和相关心理表征的进一步深化。
构建心理表征最好的方法是长、短时记忆联合。比如我们能够背诵内外妇儿传书上的理论和执业医师的知识点，但这只是一些短时记忆，很容易遗忘。只有通过参与临床工作将这些短时记忆变成长时记忆，并加以自己的分析归纳，才会变成自己的心理表征，而不断累积这种心理表征的过程也就是训练临床能力的过程。
比如说遇到一个病人同时有耳痛和瞳孔小的症状，尽管我们之前已经在课本上学过“霍纳综合征”的理论知识，考试也经常考这个概念，但是当在实际中见到这种情况，由于没有建立相关的心理表征，可能觉得这两个症状并不相关，因而根本就想不起这个疾病。但你的老师可能很快就会把这两者结合起来做出正确诊断，这就是他的一个心理表征的表达。如果在临床上管过这种病人，并且按照前面说的方法去深入分析诊治了这个病人从而建立起了自己的心理表征，可能下一次，你就会和老师一样很快做出判断。所以，我们可以这样说：
临床=心理表征的初级表现形式。
