Example Input: Article: Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers. Of course sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, they inquire into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however. the new rules came too late to protect the people who died or who became seriously ill. Today many governments have special departments which protect customers and workers.In the U.S, for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work. and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness. but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.

Example Input: Article: Criticism is judgement.A critic is a judge.A judgement study and think about the material presented to him, accept it, correct it, or reject it after thinking over what he has read, watched or heard. Another word for criticism is appreciation.When I criticize or appreciate some objector another, I look for its good points and bad points.In reading any printed or written matter, I always have a pencil in hand and put any comments in the book or on a separate paper.In other words, I always talk back to the writer. That sort of critical reading might well be called creative reading because I am thinking along with the author, asking him questions, seeing whether he answers the questions and how well he answers them.I mark the good passages to store them in my memory piece of writing; where, how and why could or should I improve upon it? You might think that doing what I suggested is work.Yes, it is, but the work is a pleasure because I can feel my brain expanding, my emotion reacting and my way of living change. Reading exercises is a great influence on a person.If pictures, still or moving, accompany the reading, the memory will retain the material for a long time. Just as evil books can corrupt, so also can good books gradually work a change on a corrupt person. Let's get back to the beneficial effects of thinking while reading.It helps us to enlarge our minds.We understand more about the universe, its people and many of its wonders.We learn to think and observe in new ways.We certainly do get a feeling for the language we are reading.All good writers in any language have been readers who read critically and continuously.

Example Input: Article: One day while shopping in a small town in southern California,it was my misfortune to be approached by a clerk whose personality conflicted with mine. He seemed most unfriendly and not at all concerned about my intended purchase. I bought nothing,and marched angrily out of the store. My hostility toward that clerk increased with each step. On the outside,standing by the road,was a darkskinned young man in his early twenties. His expressive brown eyes met and held mine,and in the next instant a beautiful, dazzling smile covered his face. I gave way immediately. The magnetic power of that smile dissolved all bitterness within me,and I found the muscles in my own face happily responding . "Beautiful day,isn't it?"I remarked,in passing. Then,I turned back."I really owe you a debt of gratitude ,"I said softly. His smile deepened, but he made no attempt to answer.A Mexican woman and two men were standing nearby.The woman stepped forward and volunteered, "Sir, but he doesn't speak English.Do you want me to tell him something?" In that moment I felt transformed .The young man's smile had made a big person of me.My friendliness and good will toward all mankind stood ten feet tall. "Thank you?" The woman seemed slightly puzzled. I gave her arm a friendly pat as I turned to leave."Just tell him that," I insisted."He'll understand.I am sure !" Oh, what a smile can do! Although I have never seen that young man again, I shall never forget the lesson he taught me that morning.From that day on, I became smile-conscious, and I practice the art anywhere and everywhere, with everybody.
