膀胱肿瘤中最常见的为下列哪种（） A.移行细胞癌 B.腺癌 C.鳞状细胞癌 D.横纹

Ⅰ．（1）某兴趣小组甲设计了以下装置和方法测定空气中SO₂含量。你认为可行的操作是             （填序号）

序号	A	B	C
装置
原理	通入V升空气，测定生成沉淀的质量	当KMnO4溶液刚好褪色时，测定通入空气的体积V	通入V升空气，测定U型管增加的质量

（2）兴趣小组乙取336mL（标准状况）某由SO₂和N₂组成的混合气体Y,将其通入足量溴水中，然后加入足量BaCl₂溶液，经适当操作后得干燥固体2．33g。由此推知气体Y中SO₂的体积分数为              。

Ⅱ某化学兴趣小组丙为探究Fe³⁺是否能氧化SO₂，设计了如下实验装置。

（1）如上图连接好装置。实验前应进行         操作 

（2）观察到装置C中产生了白色沉淀，同学们提出了以下猜想（每个猜想只考虑一种物质的氧化性）。

猜想1：                              ；

猜想2：SO₂被Fe³⁺氧化了；     

猜想3：SO₂被NO₃^—氧化了

（3）甲同学认为猜想1正确，并利用上述装置A进行了排除干扰的探究实验。

（4）乙同学认为猜想2正确，则装置C中反应的离子方程式是                  

（5）丙同学认为猜想3正确，他利用甲同学的实验装置，设计实验验证猜想。请在答题卡上写出实验步骤以及预期现象和结论。限选实验试剂：NaNO₃溶液、KSCN溶液、FeCl₃溶液、BaCl₂溶液、

Fe(NO₃)₃溶液

One of your audit clients is Tye Co a company providing petrol， aviation fuel and similar oil based products to the government of the country it is based in. Although the company is not listed on any stock exchange， it does follow best practice regarding corporate governance regulations. The audit work for this year is complete， apart from the matter referred to below.

As part of Tye Co‘s service contract with the government， it is required to hold an emergency inventory reserve of 6，000 barrels of aviation fuel. The inventory is to be used if the supply of aviation fuel is interrupted due to unforeseen events such as natural disaster or terrorist activity.

This fuel has in the past been valued at its cost price of $15 a barrel. The current value of aviation fuel is $120 a barrel. Although the audit work is complete， as noted above， the directors of Tye Co have now decided to show the ‘real’ value of this closing inventory in the financial statements by valuing closing inventory of fuel at market value， which does not comply with relevant accounting standards. The draft financial statements of Tye Co currently show a profit of approximately $500，000 with net assets of $170 million.

List the audit procedures and actions that you should now take in respect of the above matter. （6 marks）
