помогите соотнести заголовки A)Tourism has become a popular activity. Indeed, nowadays people travel more, and further, than they used to. The main reasons for tourism are: recreation, leisure and business. When travelling for recreation, people want to escape their stressful daily routine and to relax. Beach holidays are an example of leisure tourism. Business trips involve going to some distant place in order to settle business issues.B)When people travel, they broaden their horizons. Whether on a business trip or on a honeymoon, people want to explore the place they are in. They go on excursions, try new activities like diving or mountain climbing, learn about the historical background of the place, and buy souvenirs to remind them of the local cultural peculiarities. Sometimes they find out amazing facts about people and places, and about themselves, too!C)Trips can be spontaneous or well-planned, but before any planning is done, you need to decide where you want to go. Lots of people prefer places where they can enjoy the sea and the sun, that’s why tourism in countries like Turkey, Thailand, Bali, Cyprus is quite a profitable industry. People who like winter leisure activities go to ski resorts in France, Austria, Iceland, Serbia and so on.D)A new branch of tourism is ecotourism. It involves visiting relatively untouched places in remote areas. Ecotourism is often misinterpreted as any form of tourism involving wildlife - but it’s completely different from jungle tourism or safari. Eco-tourists are against disturbing the environment; even taking photos is not recommended. Take only memories and leave only footprints is a very popular slogan for them.E)By educational tourism, most people mean different versions of Learn and Travel Programmes for students. But it’s not only for the young and brave. Lots of training and educational programmes for adults are offered in different corners of the world. Retired people participate in these programmes too. They gladly enroll on overseas courses ranging from gardening and design to computer skills and programming.F)With all the benefits of travelling, it’s still a very expensive activity and may not fit every budget. To reduce the costs, avoid travelling in high season when flight tickets, hotels, food and excursions are overpriced. Remember that, as well as the well-known, popular, and therefore most expensive, destinations, there are less prestigious but even more interesting places. When planning a trip, find out about low-cost airlines, discounts and special offers.G)If possible, consider means of transport other than the plane. Rapidly increasing numbers of flights have put the environment in danger. Planes pollute the air, which results in global warming. In fact, tourism is not harmless fun as many may think: new airports and tourist infrastructure, pollution, and crowds of noisy tourists make wild animals migrate, which may decrease their population or even make them extinct.
