Leaving now the questions of formal geometrical propositions, I proceed to enumerate a few games or puzzles which depend mainly on the relative position of things. Some writers regard draughts, solitaire, chess, and such like games as subjects for geometrical treatment in the same way as they treat dominoes, backgammon, 相似文献

许多同学认为,反身代词用法比较简单,涉及反身代词的考题一般不会太难,所以对反身代词重视不够,从而在涉及反身代词的考题上丢分。请看下面两个例子：1.If our parents do everything for us children,we won＇t learn to depend on_____.（2010年上海卷） 相似文献

The answer is No.Man's best friend is colorblind, but, fortunately, his survival does not depend upon the ability to see colors. His keen sense of smell compensates for his inability to see colors, and enables him to differentiate(区分)between things.Extensive scientific testing on dogs supports the conclusion that they live in a colorless world. The testing done primarily 相似文献

解含有分母的一元一次方程是一元一次方程的难点．初学解含有分母的一元一次方程时，一些同学总是大错不犯，小错不断．究其原因，主要是没有搞清“去分母”的来龙去脉，没有真正理解“去分母”．相信，弄清楚下面几个有关“去分母”的问题之后，再解含有分母的一元一次方程时就会大大降低出错的机率． 相似文献

<正>一、知识梳理1.用字母表示数在含有字母的算式中，加号、减号、除号都不能省略。在含有字母的乘法算式中，乘号可以用“·”代替，或省略不写。2.方程含有未知数的等式叫作方程。方程必须具备两个条件：一是等式，二是含有未知数，二者缺一不可。3.方程的解使方程左右两边相等的未知数的值，叫作方程的解。 相似文献

INTRODUCTION Dynamics of carbon and water vapor fluxesexchange between the atmosphere and the ecosystembiosphere, depend on complex and non-liner interplayamong physiological, ecological, biochemical andedaphic factors and meteorological conditions (Jarvis,1995; Leuning et al., 1995). There are many studiesquantifying the fluxes across different time and spacescales as well as assessing the environment con-straints on them by some kinds of biophysical orempirical models whose resul… 相似文献

无数据计算题是指题目中不出现任何数据的一类计算题。该类计算题在近年来的各省市中考化学题中时有出现。解无数据计算题应根据题目的特点来选择不同的方法。对于不同物质中含有相同成分或变化前后质量不变等情况，巧找等量关系是解题的关键与捷径。下面举例说明：例1若SO。与SO。两种物质中含有相同质量的氧元素，求SO与SO。两种物质的质量比。用析1个SO。分子中含有2个氧原子，1个SOa分子中含有3个氧原子，则3个SO。分子与2个SO3分子含有相同的氧原子，即含有相同质量的氧元素。因此，SO。与SO两种物质的质量比就等于3个SO。分… 相似文献

条件为ab＋bc＋ca=1的一类不等式的证明 总被引：1，自引：0，他引：1
当遇到含有条件如ab＋bc＋ca=1的不等式时，如果不等式的项中含有类似于a^2＋1的项，则可以尝试用ab＋bc＋ca去代替其中的1，然后分解因式，有利于进一步分析问题、解决问题． 相似文献
