Hello, Catherine here from BBC Learning English. Just so you know, this programme is from the BBC Learning English Archive（档案馆） and was originally（ 最初） broadcast（广播） in November 2009 on our website. And now, on with the show. Newswords from the BBC. Here's Claire Arthurs. Today I'm going to talk about activism from the verb 'to act'.

  A word you'll often hear in the news is 'activist（积极分子）'. It's someone who acts for a cause which they believe in. Here's an example from a BBC news broadcast. Two peace activists have admitted（承认） breaking into an RAF base（基础） to try to stop B-52 bombers（轰炸机） taking off for Iraq. Activists usually want to achieve change, so you'll hear words like 'campaign（作战）', 'protest（主张）' and 'demonstrate（证明）'.
