解题思路：（1）量出花圃与校门之间的图上距离填写，由比例尺=图上距离：实际距离，根据题意代入数据可直接得出这张地图的比例尺．
（2）先求得教学楼距校门的图上距离，再依此画出教学楼的位置．

（1）花圃与校门之间的图上距离是2厘米．
40米=4000厘米，
这幅图的比例尺是2：4000=1：2000．
（2）60米=6000厘米，
6000×[1/2000]=3厘米．
画出教学楼的位置如下：

点评：
本题考点： 应用比例尺画图；比例尺．

考点点评： 考查了应用比例尺画图，得到这张地图的比例尺是解题的关键，注意单位要一致．

解题思路：跟怒题干叙述结合物质的性质进行分析，化石燃料的使用，增加了空气中二氧化硫和氮氧化物的含量，易形成酸雨，能腐蚀大理石雕像，根据物质的转化即可得出反应的类型．

（1）大理石雕塑腐蚀速度加快是因为受到了酸雨的腐蚀，减缓腐蚀就是减少空气中二氧化硫和氮氧化物的排放，可以减少化石燃料的使用或开发新能源等，故填：酸雨的腐蚀，减少或降低酸性气体的排放；
（2）碳酸钙高温能分解生成氧化钙，CaCO₃

高温
.
CaO+CO₂↑，属于分解反应，
氧化钙能与水化合生成氢氧化钙，CaO+H₂O═Ca（OH）₂，属于化合反应，，属于复分解反应，
故填：分解反应，化合反应，复分解反应．

点评：
本题考点： 酸雨的产生、危害及防治；反应类型的判定．

考点点评： 本题考查了化学与环境的知识以及有关反应类型的判断，完成此题，可以依据已有的知识进行．

共生现象在自然界中普遍存在，例如豆科植物与根瘤菌之间：根瘤菌将空气中的氮转化为植物能够吸收利用的含氮物质，而豆科植物则为根瘤菌提供有机物，二者互惠互利，共同生活．
故选：C

Although I had a lot of problems to solve, I believed I could solve them one by
one. One of my main goals during the first semester of senior high school
grade three was how to get rid of those bad habits. It was not long before
I adapted myself to the life in the third year of high school and gradually
got rid of those bad habits which had hindered me in my study. After
having made some efforts, my scores were improved. But to my
disappointment, I soon found out that my results seemed to be stagnant.
I got very nervous and went to the teacher for help. The teacher suggested
that I should persist in my study and improve my study method. The
teacher's words served as a dose of good medicine and very soon I got out of
the dilemma.Finally, of course, I also was admitted into the ideal university

解题思路：A．融雪盐会污染绿地河流；
B．对根据融雪盐的成分来确定其性质；
C．根据融雪盐的使用产生的危害来回答判断；
D．原电池能加快化学反应的速率．

A．融雪盐会污染绿地河流，撒了融雪盐的积雪不宜往绿地、河流中倾倒，故A错误．
B．融雪盐氯化钠、氯化镁都不能与冰反应，故B错误；
C．融雪盐会污染绿地河流，不大力推广使用融雪盐去除道路积雪，故C错误；
D．融雪盐作为电解质，与钢铁中的铁和碳构成原电池，原电池能加快化学反应的速率，会加速钢铁桥梁的腐蚀，故D正确；
故选D．

点评：
本题考点： 氯、溴、碘及其化合物的综合应用．

考点点评： 本题考查融雪盐及它产生的污染，难度不大，注意目前世界上使用的融雪盐主要有四种，包括氯化钠、氯化钙、氯化镁和氯化钾，统称作“融雪盐”．

（1）记忆不深刻.一般楼主应该是只看过一遍或者两遍吧,看过去虽然还记得,但是时间长就会遗忘.这是由人类记忆曲线决定的,改变不了.
（2）楼主应该不是学历史或者经常用历史的.如果是在一个经常提及历史话题的环境中,自然对相应的知识会不断回顾,加强记忆.而如果只有楼主一个人在了解历史知识,身边的人对此兴趣缺缺的话,楼主就比较悲剧了.
（3）没用形成完整的体系.历史时间并不一定都需要考死记硬背,当形成完整的知识体系与逻辑体系的时候,完全可以通过一些片段推断出大部分的事情.

经典题目了~好像还比我们那时简单了许多
（1）类比电力场（F=Eq）,重力场(G=mg)定义场强,
可定义风力场强度：风对小球的作用力与对小球最大截面积之比,
即E＝F/S＝k
（2）类比重力场(E=mgh)定义势能,可定义E=Fx=Skx (x为任意处距P 处的距离)
类比电力场（U=W/q=Ex）,可定义U=W/x=Skx/x =kS
(3)机械能守恒就是 第一个状态的机械能=第二个状态的机械能
在本题中,某状态的机械能=动能+风力势能
所以有
1/2 m v1平方 + Skx1 = 1/2 m v2平方 + Skx2 .(*)
m=4/3 π r三次方 ρ
S=π r平方
带入式子*得：2/3 ρ r v1平方 + kx1 ＝ 2/3 ρ r v2平方 + kx2

许多光源在发光的时候也在（发热）
这是热光源的特性.它利用热能激发的光源.如白炽灯、弧光灯等.白炽灯热辐射发光,有80－90％的能量转换能热能,10％左右的能量转换为光能.白炽灯就是典型由电能转化为热能,再将热能转化为光能的过程.热能损耗较高,因此发光效率较低.另外,我们不是根据灯具外壳的温度来定义为冷光源,还是热光源.灯具周边的温度高低,只能评判该灯具散热措施的优劣.

道理：我们做每件事都不能一成不变,创新在当今时代是最重要的,而一成不变的事物,久而久之就会被人所烦躁,其价值也就会降低更或者被否决了!

看月亮,其实很简单的,对望远镜要求并不高.
不过你说看星星和太空,这个就麻烦些,如果你是新手的话,其实最大的问题不是推荐什么样的天文望远镜,而是你买回来之后,可能会因为与想象的差别太大,而闲置.
很多人以为天文的有趣,以为自己喜欢天文,其实是因为看了一些广告,或者天文的图片.但实际上,实际的天文用起来,完全是另一回事吧：http://www.***.com/222tianwenwangyuanjing.html我担心,你可能会和大多数人一样买了后悔.
所以建议,如果你自己对天文这方面还不太了解的话,建议那别着急动手,找个商店看看实际情况,如果仍然喜欢,再下手也不迟.
别让自己成为“买回天文,发现不对,然后闲置”的那80%的人群中的一员.毕竟,就算入门的天文望远镜,也是几百元了,也不便宜,是吧.
昨天回答过一个类似的,直接复制过来.

Nowadays,the urban population get more and more crowded,which brings many problems in preventing fire hazard.Hence we are thirst for a lntelligent fire alarm with low price and good performance to prevent the possibility for fires and cut loss.Here it adopts the technology of the temperature sensor DS18B20 temperature measurement and SCM detection and alarm to expound a simple lntelligent fire alarm,which through the temperature sensor DS18B20 testing temperature,and change it to electrical signal to SCM.According to set value to judge whether it needs to give an alarm or not by Microcontroller program,if it needs,then start alarm circuit.Taking measures by users and then input the password by them to remove alarm.No imput or wrong password will continue to give an alarm.The lntelligent fire alarm has advantadges of low cost ,easy fabrication,alarm in high sensitivity and simple operation,it applies to the room of small space to prevent fires.

经历过暴风雨的美才是最美的

迎春花最好的品种是黄河流域的黄土丘陵地带的黄土崖头的野生品种,天寒地冻摆,百花凋零,而野外的一迎春却顶风冒雪,冲破严寒,将它那带有无限生机的花朵大片大片的洒向人间,低温严寒时,花骨朵鲜红,彻底开放时呈金黄色,并带有红萼,黄橙橙,金灿灿的花朵,带着红低,压满碧绿的枝条,其中的美丽,难以言表,可惜三十年的乱采滥挖,野外美景早已不见.北方迎春花盆景在楼顶露天养护时,如果是养护高手,可养出白色的树干,碧绿的枝条,红色的花萼,金黄色的花朵,四种颜色同时绽放,绝对有惊天地,泣鬼神的神奇和美丽,好好养那棵迎春花吧. 查看原帖
