перевод текста travelling by air
Man’s desire to fly first found expression in fantasy and legend. Then he began to understand the air and true flight became possible. Today travelling by air is a common thing. Many people prefer this kind of travelling because it is more convenient, more comfortable, and, of course, much quicker than any other means of transport.
If you are in a hurry and want to save up your time, you’d better travel by air because it is the fastest way of travelling. But there is one unpleasant thing about travelling by air — the price of the tickets is too high, the seats are rather expensive. But when you travel on business it makes no difference for you.
On a flight day after packing your things you get to the airport. There is a bus service from the air-fleet Agency, and the best way to get to the airport is by bus. If you are short of time, you may take a taxi. You must check in your luggage and after the procedure of registration you board the plane. Now you can hear the engines start their work. The plane is taking off. It gains speed very quickly and in a few minutes you are already above the clouds. The land below looks like a small geographical map. After the plane has gained its regular height, the stewardess brings passengers some mineral water, sometimes tea and sandwiches. The seats on board the plane are comfortable, and you can sit in a cozy armchair and read a book, magazine or a newspaper, look through the window to see the passing clouds change their colour from white to black. You may just as well have a sleep until you arrive at your airport. While you are sitting in the armchair you must fasten the seat belts. You may also lower the back of the seat and feel yourself comfortable, “as snug as a bug in” a rug”, as the saying goes. In front of you there is a cockpit where a pilot and a mechanic sit. They both and a stewardess are the crew of the plane.
If you are travelling by plane, there is one thing you’ve got to bear in mind. Some people can’t stand flying and they get airsick, in this case they have to take a pill for airsickness, and in some time they will feel much better. The stewardess will help them with their problems.
Soon the plane will land and arrive at its destination exactly on time.
