【文章內(nèi)容簡介】 The most important thing to realize is that we all have many teachers in our lives. Our parents teach us, our teachers teach us, and our peers teach us. Books and newspapers and television also teach us. All of them are valuable.Nowadays, food has bee easier to prepare. Has this change improved the way people live? Use specific reasons and examples to support your answer. The twentieth century has brought with it many advances. With those advances, human lives have changed dramatically. In some ways life is worse, but mostly it is better. Changes in food preparation methods, for example, have improved our lives greatly. The convenience of preparing food today is amazing. Even stoves have gotten too slow for us. Microwave cooking is much easier. We can press a few buttons and a meal is pletely cooked in just a short time. People used to spend hours preparing an ovencooked meal, and now they can use that time for other, better things. Plus, there are all kinds of portable, prepackaged foods we can buy. Heat them in the office microwave, and lunch at work is quick and easy.Food preparation today allows for more variety. With refrigerators and freezers。 we can preserve a lot of different foods in our homes. Since technology makes cooking so much faster, people are willing to make several dishes for even a small meal. Parents are more likely to let children be picky, now that they can easily heat them up some prepackaged macaroni and cheese on the side. Needless to say, adults living in the same house may have very different eating habits as well. If they don39。t want to cook a lot of different dishes, it39。s mon now to eat out at restaurants several times a week.Healthful eating is also easier than ever now. When people cook, they can use new fat substitutes and cooking sprays to cut fat and calories. This reduces the risk of heart disease and high cholesterol. Additionally, we can buy fruits and vegetables fresh, frozen or canned. They39。re easy to prepare, so many of us eat more of those nutritious items daily. A hundred years ago, you couldn39。t imagine the process of taking some frozen fruit and ice from the freezer, adding some low fat yogurt from a plastic cup and some juice from a can in the refrigerator, and whipping up a low fat smoothie in the blender!Our lifestyle is fast, but people still like good food. What .new food preparation technology has given us is more choices. Today, we can prepare food that is more convenient, healthier, and of greater variety than ever before in history.It has been said, Not everything that is learned is contained in books. Compare and contrast knowledge gained from experience with knowledge gained from books. In your opinion, which source is more important? Why?People always are learning and practicing through their whole lives. From reading words in text book such as toy, car, train etc. , people have the concept and ideas. They further understand the actual meaning of these words by playing toys and riding or driving cars, trains etc.Education (books) and experience are the main two channels for People to gain their knowledge. Each play different roles for people. In my opinion, knowledge from experience is more important than that from books.Experience first can prove if the knowledge form books are true or false. Textbooks are very wonderful in teaching people essential principles, how is the world looks like? what is the basic law of change of people and things? We can learn a lot through primary school, secondary school until university. However, people can only understand the really meaning of those form books and justify them if they are right through practices. A few hundred years ago, people learnt from text book that the earth was flat. However scientists found that was wrong through observations and measurement.The knowledge from experience can improve and advance the world and our society. As books have limitation, they only teach us the what people found in the past. The knowledge from the books are constrained to the certain conditions and environment. For example, mould and tools design for plastics industry, the university course only taught me very simple cases, most knowledge are obtained from various different and plicated cases in my career. There are a lot new inventions and new products which could not be found from textbooks. Our society and world are developed through continuous practices, those knowledge, never found in books, such as internet, ebusiness etc. are all developed through new practices. The truth es from practices and experience, people are continually discovering new things and assessing the creditability of the knowledge written in books. The knowledge from experience help us much more than those from books.A pany has announced that it wishes to build a large factory near your munity. Discuss the advantages and disadvantages of this new influence on your munity. Do you support or oppose the factory? Explain your position.New factories often bring many good things to a munity, such as jobs and increased prosperity. However, in my opinion, the benefits of having a factory are outweighed by the risks. That is why I oppose the plan to build a factory near my munity. I believe that this city would be harmed by a large factory. In particular, a factory would destroy the quality of the air and water in town. Factories bring smog and pollution. In the long run, the environment will be hurt and people39。s health will be affected. Having a factory is not worth that risk.Of course, more jobs will be created by the factory. Our population will grow. To acmodate more workers, more homes and stores will be needed. Do we really want this much growth, so fast? If our town is going to grow, I would prefer slow growth with good planning. I don39。t want to see rows of cheaply constructed townhouses. Our quality of life must be considered. I believe that this growth will chan
