Пожалуйста помогите с текстом. Нужно написать пересказ на английском языке. Предложений 14 минимум.


Almost all people like to travel. When you have got holidays you can travel by car, by train, by plane and by sea.

I like to travel by sea best of all. Some years ago we took a cruise along the Black Sea coast on board the liner " Russia ". We came to Sochi by train. Then we went to the seaport and saw our ship. It was big. We liked it very much. I remember the ship and our cabin. Our cabin was comfortable. It had got two berths, a table two chairs and one wide window and the warm wind was blowing through it. There was fresh air in our cabin during all the voyage. We had breakfast, dinner and supper on board the ship. When it was time to have meals we went to the restaurant.

The weather was fine. After breakfast we spent a lot of time on the deck sitting in deck chairs or standing at the rail, watching the ships, passing not far from our ship. It was pleasant to watch the waves too.

I remember the sunrise and the sunset well. It was unforgettable. In the afternoon I took a sunshade because the sun was shining brightly. It was hot in the sunshine.

In the daytime we liked to watch the sea-scape. At four o'clock we entered the port Adler. There were some ships there. We saw many people on the pier. We had some free time in Adler and we went for a walk while the ship was in the port. The water was clean and it was pleasant to swim in the sea. I like the Caucasus and that's why I was pleased.

At 8 o'clock we came back. The liner was going to sail off. In the evening we patched TV, danced or stayed on the deck when the weather was fine.

I enjoyed my trip. This voyage impressed me for all my life.
