Task. Read the text about Cinema and answer the questions.
Cinema
Cinema plays an important role in the life of any society. It is an available popular form of art.
Lots of people find going to the cinema one of the best ways of spending their leisure time. The
movie audience is predominantly a young one.
No matter how large the place you live in is (whether it's a big city or a small provincial town, or
even a settlement) there's most likely to be a cinema there.
There are such genres of feature films as the wester, the thriller, the musical, the drama and the
comedy. The performance lasts for two or three hours and most cinemas have at least 4
performances a day. There is no doubt that a good cinema show is an excellent entertainment and
quite cheap
As for me, I'm fond of going to the cinema. It's a pity. I don't always have time for it. It's an open
secret that we live in a very difficult time now. But people do need something amusing and
pleasant, something to laugh at. That's why I give my preference to comedies. The last comedy, I
saw, is «Crocodile Dandy». The film tells about amusing adventures of a young lovely woman
reporter and a strong and brave crocodile hunter. A happy end is an essential feature of American
films. The same is true of this comedy. The main characters fall in love with each other in the end
of the film.
Questions:
1.How do lots of people find going to the cinema?
2. Who makes up the movie audience?
3. What genres of feature films are there?
4. How many performances have many cinemas a day?
5. In what time do we live now?
6. What genre of film the author gives preference to?
7. What is an essential feature of American films?
