的口口
本发明可以减少负担的值日生清理粉笔槽,只需除去日常中喝光了.
缺点：增加在黑板槽的长度也增加学校经费.一些教师,促进保护和要正视一个稍微偏长的粉笔头,然后给它带来的麻烦.
其他的具体参数和设计是不公开的.
原来的想法,我希望能够激励你,也许你可以举一反三,例如,?教室的窗户和除霜器,设计通风设备的教室.
只要仔细观察就会发现,懒出境界（困难想：“如果你喜欢,那么一个目标,创造有）,有将是一个很好的发明.这可能不只是老师布置的作业这么简单. />
最后,快乐的春节,学习进度.

奢侈品,时尚商品.“You can describe clothes and things in your house as practical when they are suitable for a particular purpose rather than just being fashionable or attractive.” practical product 是指实用的衣服或物品,而不是时尚的吸引人的.所以,相对的frivolous product 就是时尚品,奢侈品的意思了.

Reading Selectively Or Extensively范文：
Some people think when we read we should read selectively.That is to say,we should select some books we are interested in and ignore the others.Reading selectively can help us concentrate our limited time and attention on those selected books.
　　Others think we should read extensively.No matter what kind of book it is,we should look it over.We should read various kinds of books,whether we are interested in them or not.They maintain that reading extensively can help to enlarge our view and grasp the general knowledge in different fields.
　　In my opinion,the two reading ways have their roles respectively in our reading.However,the disadvantages of each methods are easy to see.If we only read the books we select or prefer,the framework of our knowledge may not be complete.Our knowledge would be rather limited.And if we read without selection,we may not have so much time and energy to be specialized in one particular field.Therefore,the combination of the two methods is more reasonable.——————————————————————————————————————1,有人认为读书要有选择.首先,现代科学技术发展得很快,每天都有大量的书籍出版,不可能全看；其次,不是所有的书都是好书,所以要有所选择.2,有人认为应当博览群书.现代社会各门学科知识相互渗透,一个人要想成功,既要精通本领域的学科知识,又要涉猎其它相关领域的学科知识,因此要博览群书.3,要拿出自己的观点,既要博览群书又要有所选择.
参考：
How should we read?Should we read selectively or extensively?Answers to the question may vary from person to person.
Some people think we should read selectively.They argue that with the development of modern science and technology,more and more books are published every day.It is impossible for us to read all the books.What’s more,there are many bad books that are poisonous to our mind,and that we shouldn’t read.Since we can’t read all the books,and we shouldn’t read bad books,we must read selectively.
But others may not agree.They emphasize that the present society is not what it used to be.If you want to be successful,you must read widely and acquire knowledge in both natural sciences and humanities.If you are learned in one field but ignorant in others,you may not amount to much.Since we must have many kinds of knowledge,we must read extensively.
Who’s right?There is a lot to be said for both sides of the argument.However,I think we should read extensively first and then learn deeply about the subject we are interested in.

中心:它与很多的科目有联系,和生物叫生化.和物理叫理化.还与很多学科有联系,天文学等等.
实用:有一定的化学基础就可以自己发明点东西~~~~还有帮助你鉴别真伪.
创造性:自己动手做实验哈.还有好多好多~~~~因为“化学是研究物质的性质、组成、结构、变化和应用的科学.”
（研究物质 促进了我们对自身、以及世界的认识 利用这些认识我们可以创造、改变物质所以化学是有着实用性、创造性的中心科学）
化学是一门试图了解物质的性质和物质发生反应/变化的科学.其中物质包括自然界存在的一切物质,如地球中的矿物、空气中的气体、海洋中的水和盐、动植物体内找到的化学物质、人类创造的新物质等.反应/变化则包括因闪电而着火的树木、与生命相关的变化和由化学家发明和创造的新变化等

这个要看你个人的发展啦,如果是考研,那就学习理论的多一点
如果你是要工作的,那就最好理论+实践一起来.理论是基础,理念好,实践起来才得心应手.光有理论没有实践,那学电子就没有意义了

解题思路：（1）由题意从表中可以看出，“创新性4分且实用性3分”的作品数量6件，利用古典概型可知创新性4分且实用性3分”的概率值；
（2）由题意及图表可知“实用性”得y1分，2分，3分，4分5分，五个等级，且每个等级分别5件，b+4件，15件，15件，a+8件，利用古典概型求出每一个值对应的事件的概率，利用分布列及期望定义即可求得．

（1）从表中可以看出，“创新性4分且实用性3分”的作品数量6件，∴“创新性4分且实用性3分”的概率650＝0.12．（2）由表可知“实用性”得y1分，2分，3分，4分5分，五个等级，且每个等级分别5件，b+4件，15件，15件，...

点评：
本题考点： 离散型随机变量的期望与方差；等可能事件的概率．

考点点评： 此题考查了古典概型随机事件的概率公式，离散型随机变量的定义及其分布列，随机变量的期望，还考查了学生的理解与计算能力．

作文的真实可以为作文添上一笔.但最重要的就是先要细心审好题目.千万不可以让作文跑题,其次就是想出一个比较有新意的命题,在写的时候要明确主旨.把首尾段写的漂亮一点,精彩一些.当然了字迹工整也是很重要的.下面具体的谈谈作文技巧的细节：
　　细心审题目
　　命题作文,审题时一定要抓住题目中的关键词语,并进一步展开合理的联想,才能真正把握题目的实质.材料和话题作文,要弄清楚在材料作文与话题作文中,命题者所提供材料的不同作用.在材料作文中,所提供的材料既是考生作文立意的出发点,又是归宿点.考生一定要读懂题干,做点分析,明确主旨,再去下笔,确保万无一失.
　　巧思出新意
　　为体现可写性的命题原则,高考的作文不管是命题作文,还是话题作文大多都是宽泛的.例如《责任》这样的题目,范围太宽,无从下笔,这样的题目就要去窄作.所谓窄作,就是对题目所涉及的内容进行修饰、限制,然后再针对被限制后的某个侧面扩大其内涵.若从“我们当代青年的责任”这个角度去写,可能就容易多了.
　　主旨要明确
　　高考作文主旨不要过于含蓄.由于时间的限制,阅卷老师不会慢慢地斟字酌句,所以如果写记叙文,不管叙事多么生动,也要在行文中适当地用一两句抒情或议论语句点明文章主旨,让阅卷老师一目了然；议论文力求事例简洁新鲜,说理充分,紧扣主旨.文章要实实在在,不要过于另类,在明示主旨的基础上,张扬个性.
　　首尾亮起来
　　开篇立论的好彩头,在第一时间抓住阅卷老师的眼球,是高考作文赢得高分的关键.而结尾的感染力和吸引力,同样是拿分的一大重点.
　　字迹要清楚
　　高考语文试卷是网上阅卷,潦草的字迹、不洁的卷面有可能给阅卷人带来的不愉悦所产生的后果是可想而知的,如果字迹不清,丢失的可就不只是几分了.
　　开头结尾都要精彩
　　开头和结尾的写作大有讲究.
　　一般来说,文章开头力求做到一简二美三有哲理.简,就是开篇语言简洁,直奔主题,使阅卷老师一目了然；美,就是开头的语言能给人以美感,那么,必会打动阅卷教师的心；哲理,是一种深度,一种高度,如果都做到了,那效果肯定错不了.
　　结尾的方法也很多：总结全文,以揭示主旨；展示未来,以鼓舞斗志；抒发情怀,以增强文章感染力；造语含蓄,使读者掩卷而思仍遐想不已.
　　只要根据以上的方法去写作文.相信你的作文一定会拿高分的.

吸热反应通常有：
①大多数的分解反应,分子分解成原子
②一些晶体的反应,如氢氧化钡晶体和氯化铵
③C、H2、CO作还原剂的氧化还原反应
④铵盐+碱
至于实用性.是用在哪一方面的降温啊.工业还是生活啊.PS：硝酸铵溶于水不是化学反应吧.只有键断裂而没生成.

知识产权中.新颖性是指产权人运用了新的方法或者手段来研究从而得出的结论,而研究的问题则在以前有人提出过.创造性是指产权人重新开辟了一条新的知识或者发现新的问题做出的研究结构.比如02年的留守儿童观点的提出就是一种创造性,而在这之后又不断有人进行深入的研究或者用不同的方法研究,这是一种方法上新颖性的表现.实用性是指该理论或者观点的提出对实践的知道程度.
逻辑关系为实用性不一定具有新颖性与创造性,创造性包含新颖性.他们的关系是处于同一个级层

[“画出好成绩-通过思维导图提高分数”读后感]读“画出好成绩-通过思维导图提高分数”有感读“画出好成绩-通过思维导图提高分数”有感 　　学习要讲究方法,老师们常将此话挂在嘴边,可是要讲究什么方法?读了很多这方面的书,都觉得只是提及泛泛的理论,没有实际价值,读过“画出好成绩”这本书,让人耳目一新,其实几年前听过一次类似的讲座,已经尝试使用这个方法,感觉很有效果,“画出好成绩-通过思维导图提高分数”读后感.　　一、思维导图的原理.　　1、人脑的工作机理是左右脑共同合作.　　2、思维导图则采用图形的办法解决左右脑之间的联系.　　3、思维导图就是一种学习方法.　　4、思维导图也是一种思考问题的方法.　　二、各个学科的特点.　　看完整本书后,作者对几个学科的总结很准确,后悔当年没有人这样总结,这与工作这么多年了,习惯从整体、全局的角度看问题有关.　　1、数学 　　一个严密结合在一起的大厦,就好织一件毛衣,如果中间产生一个窟窿,后果可能是整件毛衣织不成.学习者要能够从全局的角度去学习数学,这样可能效果就会很明显.数学的核心是抽象思维,比如用A代表10个苹果,用AB表示一段距离,抽象思维方面有体现.其次,数学是数字的游戏,从自然数-整数-无理数-复数这样展开与深入,用思维导图很容易将抽象的东西形象化.　　2、语文 　　语文是一个平时积累的功夫,属于墙内开花墙外香的代表,语文的知识点分散、考试范围松散,学生考试成绩不稳定,读后感《“画出好成绩-通过思维导图提高分数”读后感》.　　（1）对于诗词：找出诗词的核心字词,转化成为图形,将诗文当成故事.　　（2）对于字词：古文中的实词、虚词分类,进行汇总后用思维导图用图形展示出来.　　（3）语法：用思维导图汇总更为方便.　　（4）作文：可以在短时间内提高作文的内容及水平.　　3、英语 　　英语学科与语文很相似,用思维导图很容易从全局领略到学习的乐趣.　　三、对于思维导图方法的评价 　　从一维的文本延伸至图文并茂,我想这也符合当前网络时代读图的需要,用丰富的图形、鲜艳的颜色唤起记忆,这绝对是一种省时又高效的作法.另外当学习者能够跳出学习的范围从全局观察学习内容,他的思维也更加灵活与开放.思维导图还特别适合于合作学习,当大家在一起时就可以进行头脑风暴,一起学习的效果更是好上加好.　　目前结合思维导图还有思维导图软件,帮助人们将内容用电子的形式储存,方便更为广泛的交流.我一直在教小女儿使用这种方法,对于小学生有一定的难度,但我想今后她会掌握这种学习方法.　　推荐大家阅读这本书,会对您的学习思维产生一定的触动.　　〔“画出好成绩-通过思维导图提高分数”读后感〕随文赠言：【这世上的一切都借希望而完成,农夫不会剥下一粒玉米,如果他不曾希望它长成种粒；单身汉不会娶妻,如果他不曾希望有孩子；商人也不会去工作,如果他不曾希望因此而有收益.】

那是精炼后的值,1个环是精炼+1,2个环是精炼+2.以此类推

听力就是多听咯.看电影、美剧,做听力练习,VOA（当然这个能力要很高）等···
口语就是多说多练没有别的办法,你可以选择天天说英语.呵呵···或者去外国朋友家生活一段时间.反正用各种方式强迫自己多说!

A、NH₄C1与KCl均是白色粉末，通过观察外观不能区分，故错误；
B、NH₄HCO₃与KCl，均能溶于水，故不能区分，故错误；
C、K₂S0₄与Ca₃（P0₄）₂，均无气味，闻气味不能区分，故错误；
D、铵盐遇碱会放出氨气，氨气有刺激性气味，则（NH₄）₂SO₄与K₂S0₄前者放氨气，后者没有，故可区分，故正确．
故选D

Spain,officially the Kingdom of Spain is a country located in Southern Europe,with two small exclaves in North Africa (both bordering Morocco).The mainland of Spain is bounded on the south and east by Mediterranean Sea (containing the Balearic Islands),on the north by the Bay of Biscay and on the west by the Atlantic Ocean (containing the Canary Islands off the African coast).Spain shares land borders with Portugal,France,Andorra,Gibraltar and Morocco.It is the largest of three sovereign states that make up the Iberian Peninsula — the others being Portugal and Andorra.
Different cultures have settled in the area of modern Spain,such as the Celts,Iberians,Romans,Visigoths,and Moors.For just over five centuries,during the Middle Ages,large areas were under the control of Islamic rulers,a fragment of which survived as late as 1492,when the Christian kingdoms of Castile and Aragón completed the 770 years long process of driving the Moors out.That same year,Christopher Columbus reached the New World,leading to the creation of the world-wide Spanish Empire.Spain became the most powerful country in Europe,but continued wars and other problems gradually reduced Spain to a diminished status.The 20th century was dominated in the middle years by the Franco dictatorship; with the dawn of a stable democracy in 1978,and having joined what is now known as the European Union in 1986,Spain has enjoyed an economic and cultural renaissance.
There are a number of hypotheses as to the origin of the Roman name "Hispania",the root of the Spanish name Espa?a and the English name Spain.
Spain is a democracy which is organized as a parliamentary monarchy.It is a developed country with the eighth-largest economy in the world.[3]

一般来讲,书写燃料电池的化学反应方程式,需要高度注意电解质的酸碱性.在正、负极上发生的电极反应不是孤立的,它往往与电解质溶液紧密联系.如氢—氧

数学是最早出现的学问之一,其具有很强的实用性.
1它是计算的学问,自古以来,计算就是人们需要经常做的事情.
2 它可以记录和比较

特征?以实验为基础,能创造自然界中没有的物质,复制自然界中存在的物质.
想过啊

选c

解题思路：利用各种物质的物理性质特别是物质的颜色、状态、气味、溶解性等方面解决，同时要知道铵盐遇碱会放出氨气，氨气有刺激性气味．

A、（NH₄）₂SO₄与KCl都是无色晶体观察外观不能区分，故此答案错误．
B、NH₄HCO₃与K₂SO₄都能很快的溶于水，且溶于水时溶液无变化故不能区分，故此答案错误．
C、KCl与Ca₃（PO₄）₂均为无味物质，故通过闻气味不能区分它们，故此答案错误．
D、NH₄Cl与K₂SO₄加入碱性物质时氯化铵会放出氨气，而硫酸钾与熟石灰不反应，氨气有刺激性气味，故此答案正确．
故选D

点评：
本题考点： 化肥的简易鉴别．

考点点评： 此题是对化肥的外观进行的考查，了解它们的外观及掌握铵盐遇碱释放出氨气是解决此类题目的关键．

边看边写边听边读边想
多抄几便
最好找人听写
英语书本的话可以遮住中文想英文或遮住英文想中文
一天中早上中午下午晚上都可以稍微看看背一背（不要花太多时间）,做分时间段复习
这是我的方法,在我看来,在应试考试中,单词比语法更重要
顺带一提我的英语成绩能在班里一二名

语言需要联系.兴趣很重要.但是高中英语只注重语法.所以就得了解并记住各种要考的语法知识.所有的语言学习基础是词汇.

悬链线箱形拱桥,指的是拱轴线为悬链线而主拱截面为箱形的拱桥,用于桥梁中采用何种桥梁应该因地制宜,对各种桥型进行安全,经济,美观的综合比较后选定.如果确定采用拱桥形式,悬链线的受力情况是较好的,所以这种拱轴线形式经常被采用.
