某校化学兴趣小组的同学在阅读资料时发现,18世纪末,法国科学家拉瓦锡曾经做了这样-个实验:让水蒸气通过一根烧红的枪管,生成了一种气体。同学们对这个实验很感兴趣:难道红热的铁能与水蒸气反应?生成的气体又是什么?带着这些疑问,他们设计了如下图所示的装置进行探究。

(1)已知试管内湿棉花不参加化学反应,它的作用是                       ;

(2)若用浓硫酸来干燥气体,则从a导管出来的气体,应从                (选填“b”或“c”)端管口通入;

(3)对化学变化过程中生成的气体同学们有以下猜想:

猜想一:生成的气体可能是氢气;猜想二:生成的气体可能是                    

(4)其实红热的铁遇到水蒸气,在生成气体的同时,还会生成一种黑色固体。你认为生成的黑色固体可能是                       。

Questions from 31 to 35 are based on the following passage: As overseas sales and profits as a percentage of total sales and profits increase, there is likely to be more headquarters’ attention paid to foreign operations. Similarly, there will be pressures to centralize control in order to deal with the growing number of global competitors and the more homogenized(同质的) needs of global consumers. The need for centralization will present more challenges for MNEs in controlling their global operations.One challenge involves management’s position in foreign facilities, where manager may see the erosion of their autonomy over marketing, production, and financial decisions. To keep those managers motivated, the company needs to include more nationalities on boards of directors and use cross-national management teams to develop practices that are globally rather than nationally oriented. But with such cross-national fertilization comes the risk of clashes between cultural traditions.A second challenge for MNEs is a consequence of their size. A number of them already have sales larger than many countries’ GDPs. To manage such organizations may require even greater decentralization and more horizontal communication among subsidiaries in different countries that are mutually dependent on parts, products, and resources. This mutual dependence among subsidiaries may in turn require new hierarchical relationships within the organizational structure.

The better a company’s overseas performance is, the more necessary for the company to().

A.centralize its overseas control

B.control its global operations

C.guard against its competitors

D.present more challenges to itself
