Hello. The programme you're about to listen to was originally broadcast（广播） in May 2010 on the BBC Learning English website. We hope you enjoy it. You're listening to Newswords. BBC journalist Claire Arthurs talks about words and phrases commonly（普通地） used in news reports. Today's word Watchdog.

  Do you or your neighbours have a dog which keeps guard over the house, barking（狗叫） to alert（提醒） you when something is wrong? It's a guard dog or a watchdog, watching for signs that things are not what they should be. So too in the media（媒体）, we talk about watchdogs. We're referring to organisations which keep watch over a particular industry or sector（部门）. For example, a financial services authority would watch for wrongdoing in the finance（财政） business. The police complaints body would handle（拿） complaints against police.
