     I grew up poor, living with my wonderful mother. We had little money but plenty of love and attention.  
I was   1   and energetic. I understood that no matter how poor a person was, he could still   2   a dream.
My dream was to be a sportsman.   3   I was sixteen, I had started playing baseball. I could throw a
ninety-mile-per-hour fastball and hit anything that moved on the football field.  I was also   4  : my
high-school coach was Ollie Jarvis, who not only believed in me, but taught me  5  to believe in myself.  
He   6   me the difference between having a dream and realizing the dream. One particular   7   with Coach
Jarvis changed my life forever.
     It was the summer between my junior and senior years, and a friend recommended (推荐) me for a
summer job. This meant a chance for money in my pocket-money for a new bike and new clothes, and
the   8   of savings for a house for my mother. Then I realized I would have to   9 summer baseball to deal
with the work schedule, and that meant I would have to tell Coach Jarvis I wouldn't be playing.  
     When I told Coach Jarvis, he was as   10   as I expected him to be.  "You have your whole life to
work," he said.  "Your playing days are limited. You can't   11   to waste them." I stood before him with
my head hanging, trying to think of the   12   that would explain   13   him why my dream of buying my
mom a house and having money in my pocket was worth facing his   14   in me.
     "How much are you going to make at this job, son?" he asked. "Three twenty-five an hour," I replied.
"Well," he asked, "is $3.25 an hour the   15   of a dream?"
     That simple question made it   16   to me the difference between   17   something right now and
following a dream. I   18   myself to sports that summer, and within the year I was  19   by the Pittsburgh
Pirates to play baseball, and was   20   a $20,000 contract. In 2000, I bought my mother the house of my
dream!

材料一:第二次鸦片战争后,清政府中的部分实力派人物看到了中国在武器装备和军事技术上远远落后于西方,主张学习西方先进生产技术和练兵方法,建设近代国防。

材料二:1895年春,清政府签订《马关条约》的消息传来,正在北京会试的举人发动了“公车上书”,由此拉开了救亡图存运动的序幕。

请回答:

(1) 材料一中的“部分实力派人物”掀起了一场什么运动?这一运动的作用是什么?

_______________________________________________________________________________

(2) 材料二中的“救亡图存运动”指什么?这一运动起了怎样的作用?

某兴趣小组同学为证明NaOH溶液与稀盐酸发生了中和反应,从不同角度设计了如下实验方案,并进行实验。

方案一:先用pH试纸测定NaOH溶液的pH,再滴加盐酸,并不断振荡溶液,同时测定混合溶液的pH,如果测得的pH逐渐变小且小于7,则证明NaOH溶液与稀盐酸发生了化学反应。

(1)用pH试纸测定溶液的pH时,正确的操作是:__________________________________。

(2)简述强调“测得的pH小于7”的理由:______________________。

方案二:先在NaOH溶液中滴加几滴酚酞溶液,溶液显红色,然后再滴加盐酸,可观察到红色逐渐消失,则证明NaOH溶液与稀盐酸发生了化学反应。该组同学在向NaOH溶液中滴加酚酞溶液时,发现了一个意外现象:氢氧化钠溶液中滴入酚酞溶液,溶液变成了红色,过了一会儿红色就消失了。该小组对这种意外现象的原因作了如下猜想:①可能是酚酞溶液与空气中的氧气反应,使红色消失;②可能是氢氧化钠溶液与空气中的二氧化碳反应,使红色消失。

(3)为验证猜想①,该组同学做了如下实验:将配制的氢氧化钠溶液加热,并在液面上方滴一些植物油,然后在冷却后的溶液中滴入酚酞溶液。实验中“加热”和“滴入植物油”目的是______________。实验结果表明酚酞溶液红色消失与空气中的氧气无关。

(4)为验证猜想②,该组同学做了如下实验:取了一定量的Na2CO3溶液,在其中滴入酚酞溶液,发现溶液也呈现红色,由此可得出以下两点结论:

结论1:说明Na2CO3溶液呈_______性;

结论2:说明酚酞溶液红色消失与空气中的二氧化碳无关。

(5)该小组同学通过查阅资料得知:当氢氧化钠溶液浓度很大时,就会出现上述意外现象。请设计实验证明该方案中取用的NaOH溶液浓度过大:

①实验方法_________________________________________________,②观察到的现象_________________________________________________________。

方案三:化学反应中通常伴随有能量的变化,可借助反应前后的温度变化来判断反应的发生。如果NaOH溶液与稀盐酸混合前后温度有变化,则证明发生了化学反应。该组同学将不同浓度的盐酸和NaOH溶液各10mL混合,用温度计测定室温下混合前后温度的变化,并记录了每次混合前后温度的升高值△t(如下表)。

(6)表中x=___________。

(7)某同学在没使用温度计的情况下,通过下图所示装置完成了实验。则该同学根据______________判断NaOH溶液与稀盐酸发生了中和反应。

(8)关于实验中的细节和意外情况:

①实验中,稀盐酸必须用胶头滴管逐滴滴加,这样做的目的是___________________。

②实验过程中,要用玻璃棒不断搅拌,这样做的目的是___________________。

③在实验过程中意外发现有气泡出现,你认为原因是_____________________。

④发现盛放NaOH溶液的试剂瓶瓶口和橡皮塞上出现了白色粉末。他们依据所学的化学知识,对这种白色粉末的成分作了如下猜想:①可能是NaOH;你认为:②可能是__________;③可能是__________。
