SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING Almost any discourse--for example an editorial, an essay, a chapter in a textbook--will use more than one method. We rarely find a method in its pure state. But here, to understand the nature of each method we shall be concerned with relatively pure examples The First Method: Comparison and Contrast It is natural for us, in confronting an unfamiliar object, to set it against the familiar. We instinctively want to know in what ways it is like the familiar and in what ways different This is a simple, and essential, way of sorting out our experience of the world. As a child you naturally used the process, and as a student you have used it informally on examinations, in writing essays or in writing up reports for science experiments

SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING The informal instinctive use of comparison and contrast is useful, but we can make the method infinitely more useful in thinking and expressing ourselves, if we are systematic To be systematic means to understand the kinds of purpose for which the first method may be made We may distinguish three types of purpose. First, we may wish to present information about one item and may do so by relating it to another item with which our readers are familiar. For example, if we wish to explain the heat treatment, we may do so by comparing it with cooking which changes the structure of food
