помогите ответить на вопросы по тексту.


Almost all people are fond of travelling. It is very interesting to see new places, another towns and countries. People may travel either for pleasure or on business. There are various means of travelling. As for me there is nothing like travelling by air; it is more comfortable, more convenient and, of course, far quicker than any other means of travelling. There is no dust and dirt of a railway or car journey or troubles with changing from one train to another train.

With a train you have speed, comfort and pleasure combined. From the comfortable seat of a railway carriage you have a splendid view of the whole country-side. If you are hungry, you can have a meal in the dining-car; and if a journey is a long one you can have a comfortable bed in a sleeper.

Travelling by ship is not very popular now. That is because it has become very expensive and not many people can afford it. Bu it is very pleasant to feel the deck of the ship under your feet, to see the rise and fall of the waves, to feel the fresh sea wind blowing in the face.

Many people like to travel by car. It is interesting too, because you can see many places in a short time, you can stop when and where you like, you do not have to buy tickets or carry your heavy suitcases.
