Passage Four

The most noticeable trend among today’s media companies is vertical integration—an attempt to control several related aspects of the media business at once, each part helping the other. Besides publishing magazines and books, Time Warner, for example, owns Home Box Office (HBO), Warner movie studios, various cable TV systems throughout the United States and CNN as well. The Japanese company Matsushita owns MCA Records and Universal Studios and manufactures broadcast production equipment.
To describe the financial status of today’s media is also to talk about acquisitions (并购). The media are buying and selling each other in unprecedented numbers and forming media groups to position themselves in the marketplace to maintain and increase their profits. In 1986, the first time a broadcast network had been sold, two networks were sold that year—ABC and NBC.
Media acquisitions have skyrocketed (剧增) since 1980 for two reasons. The first is that most big corporations today are publicly traded companies, which means that their stock is traded on one of the nation’s stock exchanges. This makes acquisitions relatively easy.
A media company that wants to buy a publicly owned company can buy that company’s stock when the stock becomes available. The open availability of stock in these companies means that anybody with enough money can invest in the American media industries, which is exactly how Rupert Murdoch joined the media business.
The second reason for the increase in media alliances is that beginning in 1980, the Federal Communications Commission (FCC) gradually deregulated (解除管制) the broadcast media. Before 1980, for example, the FCC allowed one company to own only five TV stations, five AM radio stations, and five FM radio stations; companies also were required to hold onto a station for three years before the station could be sold. The post-1980 FCC eliminated the three-year rule and raised the number of broadcast holdings allowed for one owner. This trend of media acquisitions is continuing throughout the 1990s, as changing technology expands the market for media products.
The issue of media ownership is important. If only a few corporations direct the media industries in this country, the outlets for differing political viewpoints and innovative ideas could be limited.

What is the FCC’s new policy regarding media alliances

A.It allows companies to sell their stocks publicly.

B.It doesn’t allow companies to sell their stocks publicly.

C.It has eliminated all post-1980 companies.

D.It permits one company to own more media businesses at the same time.

 A .铝在地壳中含量高   B .铝相对活泼,冶炼较难   C .铝的硬度小  

(2 )铝制品具有很好的抗腐蚀性能,是因为铝在空气中其表面易形成致密的            。该变化的化学方程式为                            

(3 )比较铝和铜的金属活动性强弱,可选用上述的           (填序号)试剂进行实验。

Ⅱ.将铝片插入硫酸铜溶液中,一段时间后取出,铝片上没有明显变化,其原因是           。兴趣小组把处理过的铝片放入硫酸铜溶液中,除铝片上有红色金属析出外, 还发现有较多气泡产生,于是激发了他们的探究欲望。

【提出问题】该气体是什么呢?

【猜     想】甲同学认为可能是氧气            

乙同学认为可能是氢气              

丙同学认为可能是二氧化硫

【探究实验】闻该气体的气味,发现没有气味,排除了      同学的猜想。 对余下两种气体猜想进行如下实验:

【思维拓展】由以上探究实验可以推知,硫酸铜溶液中有        离子参与反应.
