解题思路：火车匀速直线运动过程牵引力与摩擦力平衡，根据平衡条件求解出最大速度；火车转弯过程做圆周运动，支持力和重力的合力恰好提供向心力，根据牛顿第二定律列式分析即可．

A、B、火车匀速直线运动过程牵引力与摩擦力平衡，根据平衡条件，有
P=Fv
F-f=0
联立得到
[P/v−f＝0
故v=
P
f]
当功率变大时，火车最大速度变大，即匀速的速度变大，故A错误，B正确；
C、D、火车转弯过程做圆周运动，支持力和重力的合力恰好提供向心力，如图

根据牛顿第二定律，有
F=mgtanθ=m
v2
r
解得
v=
grtanθ
故tanθ变大，即铁路转弯处的路基坡度应增大，故CD错误；
故选B．

点评：
本题考点： 功率、平均功率和瞬时功率；向心力．

考点点评： 本题关键对火车受力分析，然后运用牛顿第二定律和共点力平衡条件列方程进行分析讨论．

B

解题思路：在物理实验中，多次实验的目的一般有两个：取平均值减小误差；总结规律，避免结论的偶然性．

在探究杠杆平衡条件得实验中，我们曾多次改变力和力臂的大小，这样做的目的主要是为了获取多组实验数据归纳出物理规律，避免实验结论的偶然性．
故选A．

点评：
本题考点： 物理学方法．

考点点评： 在进行探究性实验时，进行多次实验的目的在于获取多组数据，以防止实验结论的偶然性．

解题思路：细胞质是细胞膜以内，细胞核以外的结构，活细胞的细胞质具有流动性，从而加速细胞内、外的物质交换．据此解答．

细胞壁是细胞外的一层透明的薄壁，起保护和支持细胞的作用．细胞核里含有与遗传有关的物质染色体等．细胞质是细胞膜以内，细胞核以外的结构，活细胞的细胞质具有流动性，从而加速细胞内、外的物质交换．植物细胞的细胞质里有液泡和叶绿体，液泡内的细胞液中溶解着多种物质，如营养物质、有味道的物质、色素等，叶绿体是光合作用的场所．花青素存在于叶肉细胞的液泡中．
故选：C．

问题补充：
“单位负责人”怎么翻呀?就是事业单位的一把的意思!
xxx has performed his arduous tasks with seriousness,a sense of responsibility,and profound knowledge,which have won for him widespread recognition in his prefession and have earned the respect of his supervisors and his colleagues.
单位负责人---supervisor/administrator

碘化银见光分解，并大量吸热，分解后可成为水汽的凝结核，在分解的同时大量吸收热量，有利于使空气中的水汽变为液体，通常用做人工降雨剂，冰晶石为六氟合铝酸钠、重晶石为硫酸钡，均没有此性质，干冰易升华，吸收大量的热，有利于使空气中的水汽变为液体，也可以用做人工降雨剂，但是二氧化碳气体无性质，
故选：D．

解题思路：二氧化碳的用途有：①二氧化碳既不能燃烧也不能支持燃烧，因此二氧化碳能够灭火；②二氧化碳可以做化工原料，如制汽水等；③二氧化碳的固体干冰，可以进行人工降雨，也可以做制冷剂；④二氧化碳促进绿色植物的光合作用，因此可以做气体肥料．

A、熟石灰可以改良酸性土壤等，不能用于人工降雨，故选项错误；
B、二氧化碳的固体干冰，可以进行人工降雨，也可以做制冷剂，故选项正确；
C、纯碱能做化工原料等，不能用于人工降雨，故选项错误；
D、一氧化碳能做还原剂和做燃料，不能用于人工降雨，故选项错误；
故选B

点评：
本题考点： 二氧化碳的用途．

考点点评： 本考点考查了二氧化碳的用途，二氧化碳与人类生活密切相关，在自然界中实现了碳循环．也充分体现了性质决定用途，用途又反映性质的理念．本考点基础性强，主要出现在选择题和实验题中．

I am a so called bad student. My parents have talked with me about heaps of time, but like many teenagers today, I ignored their advice and even do the opposite of them.
I think I would always be like that until my teacher asked me to her office in a sunny afternoon. I stood in front of her and my eyes were looking down.
"Do you know why are you here" Teacher said. I just kept silent."Don't you know how hard your parents are? Your performance in school has hurt them deeply?" I still kept silence."You are in the active age of your life, you should do something significant instead of having nothing to do everyday."
Knowing I had no response to her. She said:"Think over what I have said just now."
Then I went to class, what the teacher said were full of my brain, I lost myself, but after talking with my teacher, I spent a lot of time on studying and surf the Internet less and less.
