краткое инфа о древнегреческой и средневековой картах

Our Family Tradition Many people enjoy making and collecting model cars. Some hobbyists col­lect many different types of model cars. Others collect only cars from a cer­tain period or specialize in models of racing cars, antique cars or cars of his­toric value. It has become a tradition in our family to collect model cars. My granddad started the tradition when he was a little boy. At that time, model cars were very rare. Some models in our collection are unique. They are handcrafted cars made of clay or wood. My father continued the tradition. He brought model cars from every place he went to. They are of different sizes and most of them are metal. We have little models that are absolutely identical with the originals. They have every little detail of a real car. It's so interesting to look at them and wonder how such things can be created by a man. I got interested in cars from my early childhood. I saw them on the shelves and my dad told me about them. I learned a lot about cars from him — the makes, the differences between them, their history. And of course, I started adding cars to the collection, too. But most of them are not just models. I made them myself. Today a popular type of model is made of plastic and sold as a kit. They produce kits of very detailed models. Many types of vehicles, including sports cars, trucks, racing cars and unusual show cars, can be found in model kits. The kits include step-by-step instructions on how to assemble the models and need such everyday tools as a sharp knife, a small drill, glue and other simple things. I enjoy spending my free time making these little wonders. 1. Are there any traditions in your family? What are they? 2. Do you know who started them? When did they start? 3. What was the reason to start the tradition? 4. Are you going to keep that tradition when you start your own family? Why? Why not? переведите текст и если хотите ответьте за себя на вопросы.
