Помогите сроооочно!!! 27-32!!!

27. When traveling by ship, we were lucky enough to see a few dolphins. A friend of mine, an enthusiastic photographer, was the first one who noticed them. 28. The friendly animals were playing not far from the ship and most of the passengers gathered on the deck to watch them. 29. The captain said that fortunately there are a lot of dolphins in the Black Sea nowadays. 30. But he also added that people sometimes are very cruel to them. There are still cases when people try to hunt these fantastic animals. 31. The dolphins may be caught in the fishermen's nets. It makes them helpful and they die because they need the air to breathe. 32. And the water pollution is certainly the worst of the problems.
