Article: An 18-year-old high school student who had just learned to swim in the last summer vacation saved the life of a drowning Ohio boy on Friday afternoon. Tom Erickson was credited with (......)saving the life of Jason Pryor,10, in Mill Creek Park. Young Jason Pryor, from Chillicothe, was visiting s from Anchor Point when he fell into the Mill Creek. The Pryor boy had no business playing nea k*s5&u r the edge of the river, but he had no idea of the danger. The Creek, with much more water than usual for the recent spring rains, flowed fast and carried the boy around a bend and out of sight from his parents, who took Jason out there and said they had not even witnessed the incident. Luckily for Jason, one of the most unselfish students from Brentwood's Central High School was taking a walk alone through the park. As soon as he found the boy struggling in the water, Erickson jumped into the Creek and managed to pull the drowning boy out of the water. And it was reported that Erickson had never received any life-saving instruction before. "I wasn't sure I could do it," Erickson said. "I didn't know if I could swim through the river by myself, not to mention getting another person out with me." This incident should be a lesson to young children who do not know how to swim. Stay away from dangerous bodies of water. Question: Young Jason Pryor lives at _ . Yes or no, is the answer "Chillicothe, Ohio"?
Yes

Article: Preface to the fourth edition A practical English Grammar is intended for intermediate and post-intermediate students. We hope that more advanced learners and teachers will also find it useful. The book is a comprehensive survey of structures and forms, written in clear modern English and illustrated with numerous examples. Areas of particular difficulty have been given special attention. Differences between conversational usage and strict grammatical forms are shown but the emphasis is on conversational forms. 1. Explanation and examples have been brought up to date. 2. There is now more information on countable and uncountable nouns, attributive and predicative adjectives, adverbs of places, sentence adverbs, cleft sentences, prepositions, conjunctives, modal verbs, perfect tenses, infinitive constructions, the passive, purpose clauses and nouns. In the fourth edition the main changes are as follows. 3. Some material has been rearranged to make comparisons easier. For example, parts of chapters on can, may, must etc. are now grouped by functions; verbs of liking and preference have a chapter to themselves; suggestions and invitations have joined the chapter on commands, requests and advice. 4. The contents list now summaries every edition heading, and there is a new index containing many more entries references. In this edition the sign "~" is frequently used to show a change of speaker in examples of dialogue. Note also that although the sign "="sometimes connects two words or expressions with the same meaning, it is often used more freely, e.g. to indicate a transformation from active to passive or direct to indirect speech. We wish to thank all at Oxford University Press who have assisted in the preparation of the fourth edition. We would also like to thank Professor Egawa of Nihon University, Japan, Professor Rene Dirven of Duisburg University, West Germany and other colleagues for their friendly and helpful suggestions.

Article: In the past, man did not have to think about protection of the environment. There were very few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive. Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on land. Yet, we continue to use more powerful machines to cut down more and more trees. We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste is still put into rivers, but there are few laws to stop this. We also know that if the population of the countries in the world is to rise at the present rate in a few years, there will not be enough food. What can we do to solve these problems? If we eat more vegetables and less meat, there will be more food available for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept. Our natural resources will last longer if we learn to recycle them. The world population will not rise so quickly if people use modern methods of birth control. Finally, if all of us think about the problem, we will have a better and cleaner planet in the future. Question: This passage mainly tells us about _ . Yes or no, is the answer "the problems we are facing today about environment and the ways to solve them"?
No
