I had an experience of sharing. When my family moved, I had to go to a new school and study in a new class. The first test made me so nervous that I failed. I got worried and felt helpless until one of my new classmates came up to me and asked softly if I was OK. After I told him about my problem, he gave me some advice. From then on, we got to know each other and shared our ideas ,problems, and happiness. We became good friends. Sharing with friends helped me bring back my confidence and fit in with others.

My dream job in the future
My dream job is to be a writer. Reading is one of my hobbies. Whenever I am free, you can find me bury myself in the story books I am interested in. Those books help me know a lot about the world, such as history, geography, science, society and so on. I wish I could be a writer and write many good books for the people.
Now I’ve read quite a few books in Oxford Bookworm series, and written several stories. Some of my teachers and friends say they are wonderful. I wish my dream would come true.

（1）两物质都是碳酸盐，所以不能选用可选用试剂中的盐酸除去碳酸钠；碳酸不能与烧碱溶液、也不与硫酸钠溶液发生反应，因此也不可选用这两种试剂除去碳酸钠；所以选择试剂中的水把可溶性的碳酸钠从不溶于水的碳酸钙中除去；
故答案为：④；
二氧化碳能与烧碱溶液生成碳酸钠和水，而氢气不能与该溶液反应，因此可选用烧碱溶液吸收混在氢气中的二氧化碳气体；
故答案为：①；
以上除杂过程中，只涉及二氧化碳与烧碱溶液（氢氧化钠溶液）反应生成碳酸钠和水；
故选CO ₂ +2NaOH=Na ₂ CO ₃ +H ₂ O（写CO ₂ +NaOH=NaHCO ₃ 也给分）．

设父x分钟,母y分钟
0.1x+0.15y+20+15=86
x+y=400
由2式得x=400-y,代入1式,解得y=220
所以x=180

（1）根据动量守恒定律得
mv ₀ +2mv ₀ =（m+m+3m）v
解得v=0.6v ₀
（2）设经过t时间，A与C相对静止，共同速度为v _AC ，此时B的速度为v _B ，由动量守恒得
mv ₀ +2mv ₀ =（m+3m）v _AC +mv _B
根据动量定理得
对A：-μmgt=m（v _AC -v ₀ ）
对C：（μmg+2μmg）t=3mv _AC
联立以上三式
v _AC =0.5v ₀ ，v _B =v ₀
（3）AC相对静止前，AB做匀减速运动，C做匀加速运动，三个物体的加速度分别为
a _A =
μmg
m =μg
a B =
2μmg
m =2μg
a _C =
μmg+2μmg
3m =μg
AC相对静止后，AC做匀加速运动，B做匀减速运动，三个物体的加速度分别为
a _A ′=a _C ′=
2μmg
m+3m =0.5μg
a _B ′=a _B =2μg
最终三个物体一起做匀速直线运动．
从开始运动到三个物体都相对静止，A、B相对于地的位移分别为
s _A =

v 20 -
v 2AC
2 a A +
v 2 -
v 2AC
2 a A ′ =0.485

v 20
μg
s _B =
(2 v 0 ) 2 - v 2
2 a B =0.91

v 20
μg
所以A与B最终相距△s=s ₀ +s _B -s _A =s ₀ +0.425

v 20
μg
（4）设整个运动过程中AC相对于滑行的距离为s，则B相对于C滑行的距离为s+△s-s ₀ ．
根据能量守恒定律得
μmgs+2μmg（s+△s-s ₀ ）=
1
2 m
v 20 +
1
2 m(2 v 0 ) 2 -
1
2 (m+m+3m) v 2
解得s=s ₀ +0.425

v 20
μg
整个过程中A、B与木板C因摩擦所产生的热量分别为
Q _A =μmgs
Q _B =2μmg（s+△s-s ₀ ）
代入解得

Q A
Q B =
5
27
答：
（1）最终A、B、C的共同速度为0.6v ₀ ．
（2）运动过程中A的最小速度为0.5v ₀ ．
（3）A与B最终相距得s ₀ +0.425

v 20
μg
（4）整个过程中A、B与木板C因摩擦所产生的热量之比为5：27．

sharing is a fantasty exerprience that benefits both of you and your friends.For instance,my parents bought Harry Potter series as my birthday present.I loved it basically because the stories in the book can enlarge my imagination and provide a spiritual world when i feel exhausted.I shared the book with my friend lily.Our friendship strengthen through this sharing exerprience.

解题思路：除杂的原则：首先要能除掉杂质，又不能和需要的物质反应，同时也不能添加新的杂质，另外，实验操作越简单越好．根据杂质的状态不同，要把杂质转化成沉淀，可溶性物质或气体而除去．

（1）CaC0₃粉末中混有Na₂C0₃时，因为CaC0₃不溶于水，Na₂C0₃溶于水，故可以用水溶解即可，答案为：④；H₂中混有C0₂，选择一种能与C0₂反应，不与H₂反应的物质，把C0₂吸收掉即可，故答案为 ①
（2）除去CaC0₃粉末中混有的Na₂C0₃时没有发生化学反应；二氧化碳和氢氧化钠反应的化学方程式：C0₂+2NaOH=Na₂C0₃+H₂0（或C0₂+NaOH=NaHC0₃）．

点评：
本题考点： 物质除杂或净化的探究；书写化学方程式、文字表达式、电离方程式．

考点点评： 除杂质时主要根据杂质的性质，把杂质转化成与原物质状态不同的形式而除去．

I have had many moving experiences in my life, and the most impressive thing I remebered was how my father took care of me when I was seriouly ill once.
it happened when i was only nine years old. i got a fever at night. My parents took me to the nearest clinic as quickly as possible. it was a cold winter night. As we were hurry, we forgot to take a thick coat for me. My father took off his coat to protect me from coldness and carried me on his back to hurry to the clinic quickly. I was deeply moved at that time. At that moment, i thought when i grow up, I must take care of them to repay them.
