The purpose of a narrative report is to describe something. Many students write narrative reports thinking that these are college essays or papers. While the information in these reports is basic to other forms of writing, narrative reports lack the "higher order thinking" that essays require. Thus narrative reports do not, as a rule, yield high grades for many college courses. A basic example of a narrative report is a "book report" that outlines a book; it includes the characters, their actions, possibly the plot, and, perhaps, some scenes. That is, it is a description of "what happens in the book." But this leaves out an awful lot.
Being one of the most widely spread elements in existence, silicon throughout the history of human civilization played a very important role in architecture and construction, because it served as a component of many building materials, such as glass, concrete and stone. The most dramatic impact of silicon on the human existence and the world’s economics was caused, however, only in the 20th century, when it became widely used in the production of semiconductors and transistors that have later evolved into computer chips, laying a foundation for the whole information industry that is one of the most characteristic features of modern times.
