In the past, when people had problems, they went to their families or friends to get advice. Today it is possible to get advice from radio shows, TV programmes and telephone hot lines, too. Most telephone hot lines are completely anonymous---callers do not have to say their names or telephone numbers. Most hot lines are usually free, too, even if the calls are long distance(距离). Other hot lines pay their advisers for their work. Usually the advisers are professionals with years of education and experience, but sometimes, the advisers have only taken a short class before starting to work on the hot line.
