Read the text carefully and do the exercises given. Everybody loves movies. We see them at theatres and we watch them on TV. They are popular with children and adults, too. We can learn from them or we can have a good time watching them. We also call movies ‘motion pictures’. ‘Motion’ is a noun for ‘moving’. People tried to show motion in pictures for centuries. Even prehistoric artists showed animals running in their cave pictures. Near the end of the 19th century, several Europeans and Americans tried to make movies. No one knows who made the first one. New York City had the first movie theatre in 1894. People put money in a small machine and looked into it at the movie. By 1900, movies were popular all over Europe and the United States. They were not very good, but people liked them because they were new and different. Every year people invented ways to make movies better. They invented machines to show the pictures on a screen. Then everyone could see the motion pictures on the front wall of a theatre instead of inside a small machine. In 1927, inventors add sound to movies. Then they added color. Today it costs several million dollars to make a movie. However, movie makers collect million dollars from people at movie theatres because everyone loves movies. ---------------------------------- Decided whether the statement are True (T) or False (F). 1 .
