In the United States and in many {{U}}(51) {{/U}} countries around the world, there are four main ways for people to be informed {{U}}(52) {{/U}} developments in the news: Newspapers, magazines, and {{U}}(53) {{/U}} or television news broadcasts. A person may use one, or all, of these {{U}}(54) {{/U}} for information. Each source is useful in its own way. Newspapers and magazines can give much {{U}}(55) {{/U}} about a particular event. They may provide some history of the event, some of its causes, some of its effects, or perhaps give an opinion or point of view on a particular development. Radio and television can help a person to be well-informed about what is {{U}}(56) {{/U}} each day. It is also possible to listen to the radio or {{U}}(57) {{/U}} TV and do something {{U}}(58) {{/U}} at the same time. Many people can listen to the news {{U}}(59) {{/U}} their car radio while {{U}}(60) {{/U}} somewhere. For the student of English {{U}}(61) {{/U}} a foreign language, an English language newspaper may be the most helpful news source {{U}}(62) {{/U}} will also give you practice in reading English.

Each part of the newspaper {{U}}(64) {{/U}} stories about different kinds of news. Some sections have a lot of advertisements which may be helpful if you want to save money. By reading the {{U}}(65) {{/U}}, you may find something you want on sale. Or you may find that two stores are advertising the same thing, but at one store the {{U}}(66) {{/U}} is lower. Other sections may have fewer advertisements or have only a specific type of advertisement to interest the people who read that section of the paper. The first section of the paper usually has the most important {{U}}(67) {{/U}} in it. Important {{U}}(68) {{/U}} in national and international government and politics will be mentioned in the first section, and usually {{U}}(69) {{/U}} the first page. Other news that is important to the people {{U}}(70) {{/U}} read the paper will also be in the first section. For example, The New York Times usually has stories about national and international news on the first page. There and on the other pages of the first section, the Times also has news about New York City and other nearby areas. This local news is important to many people who read The New York Times.

We 3 the world not according to direct knowledge of reality, but according to mental models, which people often mistake 4 reality. For example, we all share a built-in mental model that the world is continuous, 5 our eyes tell us differently. This built-in mental model tells us what to "see" in a part of the eye that doesn''t 6 see anything. This "blind spot" model causes us to 7 made-up information (a continuation of surrounding patterns ) and 8 that if we look at a previously hidden spot, it will look like its 9 .   Not all mental models are built in; some we learn or 10 . For example, most people believe that the automobiles driving down the street will not turn 11 the sidewalk and hit pedestrians. If we believe 12 , we would act like 13 squirrels, always stopping to look around and proceeding 14 no automobiles were operating nearby.   We use mental models of our surroundings to perceive what we believe to be 15 and to predict what may happen. These mental models 16 to our surroundings--we have mental models of objects ,of the environment ,and of other people--and to our own capabilities and 17    All of our mental models are, unfortunately, approximations 18 in the lump of nervous tissue we call the brain.
