单项选择题

Newspapers, along with reporting the news, instruct, entertain, and give opinion. An important way for reading a large, big-city newspaper is knowing how to take it apart. Can you iliad these separate sections: world news, national and local news, sports, business, entertainment, opinions, classified ads Does your paper have other sections
News stories give facts, not the author’s opinions. Editorials do the opposite: you can expect an editorial to take sides. Some newspaper editorials have a by-line with the author’s name, but many newspapers have unsigned editorials. These reflect the opinions of the publisher or editor.
You can be a better reader if you know what to expect in a newspaper. For example, you can expect headlines to omit unnecessary words. You can expect to find the most important facts in the lead paragraph (the first paragraph) of a news story. You can expect important news items to be on the front page. You can expect less important items to be on the inside pages.
Most of all, the more you know about the current news, the more you will understand what is in the newspaper; important stories are generally presented one day and followed up on following days. So, an important way for reading newspapers is reading one frequently.
