解题思路：本题可根据总耗油量=A市运往汶川和北川的耗油量的和+B市运往汶川和北川的耗油量的和．然后化简得出总耗油量和吨数的函数关系，然后根据函数的性质来判断出耗油量最少的方案．

（1）由题意得：y=0.5x+（500-x）×0.8+（400-x）×1.0+[300-（400-x）]×0.4，
∵因为B市只有300吨物资，
∴A市至少要运送400-300=100吨物资到汶川且最多运送400吨物资到汶川，
即100≤x≤400，整理得y=760-0.9x（100≤x≤400）．
（2）要使y最小，则要x取最大值，即x=400，代入上式得y=760-0.9×400=400（升）．
方案是从A市运送400吨物资到汶川，其余物资全部运送到北川．

点评：
本题考点： 一次函数的应用．

考点点评： 本题主要考查了一次函数关系式的应用，注意自变量的取值范围不能遗漏．

解题思路：通过理解题意可知本题存在两个等量关系，即10辆车10天运送的救灾物资=原先库存的物资+这10又新运到的救灾物资，15辆车5天运送的救灾物资=原先库存的物资+这5又新运到的救灾物资，根据这两个等量关系可列出方程组．根据一辆车一天运送的吨数和每天从全国各地进入这个中转站的救灾物资的吨数，可求得每天要安排的车辆．

（1）设每辆货车每天运送x吨救灾物资，每天从全国各地进入这个中转站的救灾物资有y吨，则


10×10x＝500+10y
15×5x＝500+5y，
解得

x＝10
y＝50．
故每辆货车每天运送10吨救灾物资，每天从全国各地进入这个中转站的救灾物资有50吨．
（2）设中转站每天要安排z辆货车运送救灾物资，则
3×10z≥3×50+500，
解得z≥21[2/3]．
∵z为整数，
∴z最小为22．
故中转站每天至少要安排22辆货车运送救灾物资．

点评：
本题考点： 二元一次方程组的应用．

考点点评： 解题关键是弄清题意，找合适的等量关系，列出方程组．应注意的是车辆是整数，不存在分数，所以若出现小数，应该进上去．

解题思路：求中位数要把数据按从小到大的顺序排列，位于最中间的一个数或两个数的平均数为中位数．

先将原数据按从小到大的顺序排列为25，30，30，35，40，50，105；
故中位数为35；
故选C．

点评：
本题考点： 中位数．

考点点评： 注意找中位数的时候一定要先排好顺序，然后再根据奇数和偶数个来确定中位数．如果数据有奇数个，则正中间的数字即为所求；如果是偶数个，则找中间两位数的平均数．

利用化学式体现的宏观与微观的意义解决A、B两选项；利用元素的质量比等于元素原子量和的比解决C、D选项，质量分数最大即原子量和最大的元素．
此题是对化学式意义及简单计算进行的考查，涉及到化学式的意义的利用，元素的质量分数的计算，抓住化学式是解题的关键．
A、因为有一种高效消毒剂的主要成分为三氯异氰尿酸（C ₃ O ₃ N ₃ C ₁₃ ），所以不能判断该消毒剂只有高氯精，因此该物质含有4种元素说法错误，故此选项错误．
B、高氯精中有四种元素，一个分子中含有12个原子，故此选项错误．
C、元素的质量比等于元素原子量和的比，则有高氯精中C、N两种元素的质量比为：（12×3）：（14×3）=12：14，故此选项错误．
D、质量分数最大即原子量和最大的元素，分析知氯元素质量分数最大，故此选项正确．
故选D

Love in the earthquake
May 12, 2008, a magnitude about 8.0 large earthquake has taken place in Wenchuan County at Sichuan Province,China. In spite of the big earthquake, we will not shake the resolve and even bigger rain, we poured immortal love. Without frontiers, Chinese people’s love spread in the disaster.
State leaders WEN arrived immediately to comfort victims; People’s Liberation Army use their own lives to created the miracle of lives; Young teachers used their own body to resist the students who are facing collapse of rubble; Husband and wife kissed each other to let the other side have the strength to live; Health care workers use their own due diligence to guard life; Victims were in mutual consolation, All the Chinese people attepmt their own strength in this moisture-torn land of the Sichuan. And, this is love, true love, can not be copied in other countries like ours.
第二段
May 13 afternoon, Dujiangyan, a collapse of the riverside homes, dozens of rescue personnel were in the their relief efforts. Suddenly, a shocking scene in front of the rescue workers took place: a young mother used her two hands to protect her three or four months-old baby away from the ruins, with her head low, kneeling on the ground, both hands were holding up the body. Her T-shirt was in a mess, and had already lost her breath. With some efforts, people managed to clean up the ruins, in her body was her child who was wrapped in a small yard . Because of the asylum of her mother , the baby was not injured, even she was in a quiet sleep, her sleeping face made all the people feel the love of warmth. Doctors opened the quilts to examine the child, and they found a cell phone in the yard, on the screen written the message :Dear Baby, if you can live, you must remember that I love you” The great maternal love, gave her children a rebirth.
第三段
Parental love is the greatest.And in the disaster, our soldiers are like our parents, give our boundless love.
In this disaster, because of the advent of aftershocks, commanding officers ordered rescue soldiers to save the persons who were under the rubble immediately withdraw. At this time, one of the soldiers found an alive child under the ruins , he stormed into the ruins, while his comrades-in-chief pulled him and denied his action, He cried out to his comrades-in-chief "PLEASE, let me do, I also get rescued one person!" and at this time, collapsed the ruins .In the end, this child has no breath any more, this soldier took the child's body, Cring ,Crying. This display the human nature, a love of tears. A major disaster love!
第四段

端午节：
The Chinese Dragon Boat Festival is a significant holiday celebrated in China, and the one with the longest history. The Dragon Boat Festival is celebrated by boat races in the shape of dragons. Competing teams row their boats forward to a drumbeat racing to reach the finish end first.
The boat races during the Dragon Boat Festival are traditional customs to attempts to rescue the patriotic poet Chu Yuan. Chu Yuan drowned on the fifth day of the fifth lunar month in 277 B.C. Chinese citizens now throw bamboo leaves filled with cooked rice into the water. Therefore the fish could eat the rice rather than the hero poet. This later on turned into the custom of eating tzungtzu and rice dumplings.
The celebration's is a time for protection from evil and disease for the rest of the year. It is done so by different practices such as hanging healthy herbs on the front door, drinking nutritious concoctions, and displaying portraits of evil's nemesis, Chung Kuei. If one manages to stand an egg on it's end at exactly 12:00 noon, the following year will be a lucky one.
