Inventions That Have Revolutionized Our Lives

Compared to 100 years ago, the world of today is becoming so much closer than ever that people can easily attain whatever they want. As Alvin Toffler says in his book, "The Third Wave," modern society is characterized as an information society, in which people's lives are dramatically and unimaginably changed, in fact, to the better. Satellites and computers are good examples of inventions leading to an information society.

Hook: Quote by an expert.

Thesis: Satellites and computers are good examples of inventions leading us to be an information society.

Purpose: To show the reader how satellites and computers are inventions which give us information and, as a result, greatly benefit society.

Method: Development by example.

MAP: Satellites and computers1.

1. The House of Life

How many decisions do people make in their lives? There could be thousands of decisions in one person's life. However, only a few of them will have a great influence. A metaphor of building a house shows how the five most significant decisions are related to one another and reflect on people's lives. The five most important decisions concern education, career, marriage, residence, and religion. (Adapted with permission, Lunging Hsieh, Taiwanese)

2. Good Students

University study is challenging. Some students succeed and some do not. What makes some students more successful at academic study than others? It depends a lot on the attitude of the student. Sandy Calhoun, a master's candidate at the University Of Missouri School Of Journalism, is an example of what professors call a good student. Sandy has a positive attitude about succeeding in an academic setting. He cares about learning, puts in time on his studies, and is interested in the world around him.
