听力原文： The two most famous faces in Britain today belong to two women who appear on television almost every night. If you open any popular magazine or newspaper you'll almost certainly see an article about one of them, with lots of photographs. Their names are Susan Rippon and Anna Ford. Susan reads the 9 o'clock news on BBC Television, and Anna reads the 10 o'clock news on Independent Television.
Most news announcers on British television are men, and when Susan began her job at the BBC three ago, she was the first woman news announcer. Newspapers and magazines started to take an interest in her and reporters started to write about her. Last year, Independent Television also decided to have a woman news announcer and they chose Anna Ford. Newspapers and magazines showed a great interest in her, too.
When Anna read the news for the first time on the 10 o'clock program, millions of people who don't normally watch the program decided to watch it that night, to see Anna ford.

听力原文： Movies are the most popular form. of entertainment for millions of Americans. They go to the movies to escape their normal everyday existence and to experience a life more exciting than their own. They may choose to see a particular film because they like the actors or because they've heard the film has a good story. But the main reason why people go to the movies is to escape. Sitting in a dark theatre, watching the images on the screen, they enter another world that is very real to them. They become involved in the lives of the characters in the movie, and for two hours, they forget all about their own problems. They are in a dream world where things often appear to he more romantic and beautiful than in real life. The biggest "dream factories" are in Hollywood, the capital of the film industry. Each year, Hollywood studios make hundreds of movies that are shown all over the world.
American movies are popular because they tell interesting stories and they are well-made. They provide the public with heroes who do things the average person would like to do but often can't. People have to cope with many problems and frustrations in real life, so they feel encouraged when they see the "good guys" win in the movies.
