There are many types of reports. A report is simply an account of something that has happened. The commonest are news reports. We get them in newspapers, over radio and on television. Sometimes cinemas also show us newsreels(新闻影片).

The main purpose of a newspaper is to provide news. If you examine a newspaper closely, you will find that there are all types of news: accidents, floods, fires, wars, fashions, sports, books, etc. The news covers everything that happens to people

and their surroundings. Sometimes there are news items which are very amusing.

A news report is usually very short, except when it is about something very important, but it contains a lot of information. It is also written in short paragraphs. The first paragraph is in fact a summary of the news item. It gives all the necessary information, what, when, where, how and why. The other paragraphs give full details of the subject. There may also be interviews with people. The words actually spoken by them are within inverted commas(引号).

Often there are photographs to go with the news to make it more interesting.
