A、The sea can hardly be trusted even on a fine day. B、It is not safe for people to go boating in the open sea. C、People who know

Mr. Johnson was born in a little village near the coast and went to school in the nearest seaside town, but he was not a lover of the sea. Even when walking along the sands, he was afraid of being cut off by the tide. Mr. Johnson was not a very good swimmer, so perhaps this was why he disliked the sea.
    After working for some years in London, Mr. Johnson was transferred to a town near the coast and, of course, the family often made trips to the beach. One day his children asked him to take them out into the bay in a boat. The sun shone brightly. There was little wind and the water was calm. So Mr. Johnson hired a boat and rowed out into the bay with his two children. They went farther than they had intended, past the cliff and out into the open sea. At first all went well, but when they decided to turn back they found themselves faced with difficulties. A strong wind had sprung up and the currents were rather dangerous.
    Mr. Johnson rowed hard, but it seemed they were making little progress. The children were waving to attract the attention of the people on the beach. Just then a motor-boat appeared from the direction of the bay. Their trouble had been noticed and the motor-boat had come to their rescue. A rope was soon attached and their boat was pulled back round the cliff to the shore.
    Mr. Johnson’s dislike of the sea became even stronger after the experience.
