When people find something valuable and return it to its owner, they are often given a reward. This is because the person not only found what was lost but also spent time   46  its owner or taking it to the police station.

There was once a young boy   47  found a woman’s purse in a shopping centre. Inside the purse there   48  some money and the woman’s driving license. Her name and   49  were printed on the license, so the boy knew where she lived. That evening he went to her house and   50  her door. When she opened it, he said, “ I found your purse,” and handed it to her.

“Thank you very much,” she said. She opened her purse and took out all the money. She wanted to give the boy a small reward,   51  there were only bills of ＄20 in the purse and she thought that $ 20 was too   52  to give the boy. “ I’m sorry,” she said, “ but I don’t have any small    53  to give you.”

The boy said, “That’s all right,” and he went away.

A few days later he found   54  woman’s purse. It also had her driving license in it, so he knew where she lived. He went to her house and said “ I found your purse,” and handed it to her.

“Thank you very much, “ she said. She opened her purse and took out all her money.

“That’s   55   ” , she said, “ Before I lost my purse I had a $100 bill and a $20 bill in it. Now I have a $100 bill, a $10 bill and two $5 bills.”

“Yes,” the boy said, and smiled.

2011年11月，中国残疾人艺术团赴缅甸慈善义演。演出在如梦如幻的芭蕾手语诗《我的梦》中拉开序曲，聋人舞蹈《千手观音》、缅文歌曲《外外赛赛》、京剧《三岔口》及合唱《天下一家》-------演出在乐观的手语诗《生命的永恒》中圆满结束。中国残疾人艺术家们，以震撼心灵的表演、自强不息的精神和不向困难屈服的尊严，诠释了生命的伟大、顽强和美好，展现了中国的开放和残疾人艺术家们的国际视野，深深征服了缅甸观众。

结合材料，运用创新意识哲学知识，说明文化单位如何推出更好更多的文化产品？（7分）

（15分）某校化学兴趣小组为探究SO₂气体的还原性设计了如下装置图：

（1）SO₂气体还原Fe³⁺的离子反应方程式为                        ；

（2）实验中所需的SO₂气体可以用浓硫酸和铜反应来制取，该反应的化学方程式为

                                      ，在反应表现了H₂SO₄的哪些性质           。

（3）装置C的作用是                                                 。

（4）若要从A中得到溶液提取晶体，必须进行的实验操作步骤：蒸发、冷却结晶、过滤、自然干燥，在这一系列操作中没有用到的仪器有            （填字母序号）。

A．蒸发皿

B．石棉网

C．漏斗

D．烧杯 E．玻璃棒   F．坩埚

（5）在上述装置中通入过量的SO₂，为了验证A中SO₂与Fe³⁺发生了氧化还原反应他们取A中的溶液，分成三份，并设计了如下实验：

方案①：往第一份试液中加入KMnO₄溶液，不变红，紫色褪去。

方案②：往第二份试液加入KSCN溶液，不变红，再加入新制的氯水，溶液变红。

方案③：往第三份试液加入用稀盐酸酸化的BaCl₂，产生白色沉淀

上述方案不合理的一个方案         （填数字序号），原因是                        。

（6）上述装置中能表明I^-的还原性弱于SO₂的现象是                           。
