     A wellmade film offers a whole world of things to watch. First there are the story aspects-the plot,

characters, dialogue and themes. Then there are the technical aspects-the camera work, cuttings and

special effects. And there are many other things, like the credits, musical score and the acting. A

wellmade film offers much more than you see in one viewing.

     Films are a means of communication. They can tell you things, just as newspapers do, or television,

or any other means of communication. Sometimes they communicate important things to you, like ideas

or lifestyles or ways of looking at the world. Sometimes people are aware of this, and sometimes not.

The more you are aware of this,the better you are.

     Notice, for example, the way films sometimes affect fashion. A star dresses or wears her hair in a

certain way, and suddenly everyone is imitating her. Boys in the 1950s could sometimes be seen wearing

black leather jackets, idling (闲逛) on street corners and smoking cigarettes. They were imitating

Marion Brando. His films taught them a certain way to behave.

     Films can also teach politics. In Star Wars, the heroes were a bunch of lovable incompetents fighting

with guts (胆量) and not much else. They were, in fact, rather like the British in the early days of WW?

. Their  enemies, like the Nazis, had a big advantage in equipment and numbers of troops, and they were

like the Nazis in discipline and heartlessness too. The whole film, in fact, was a rerun of WW?, and taught values like faith and love of liberty. This is all to the good, but the point is, did you notice it?

1. All of the following are mentioned as noticeable   aspects of a film EXCEPT________.

A. the list of names of actors and directors, etc.

B. the cost of a film

C. the music for a film

D. the language used in a film

2.The last sentence in Paragraph 1 probably means ________.

A. a high quality film can be appreciated repeatedly  from different angles

B. a good film always attracts a lot of viewers

C. a wellmade film usually has more than one theme

D. one can never find out how many characters there    are in a good film

3. It can be inferred from the passage that in his film, Marion Brando was ________.

A. a motorist who always wore a black leather jacket

B. a homeless man who died of excessive smoking
