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.
