     One Sunday, Mike decided to go sailing in his boat with his friend Jack. But Jack happened to be

away. Jack's brother, John, wanted to go with him, but he didn't know anything about sailing. Mike

agreed and they started to go out to sea.

     Soon they found themselves in a thick fog. Mike was sure they would be hit by a big ship. Luckily,

he saw a large buoy(浮标) through the fog and decided to tie(系) the boat to it for safety. As he was

getting onto the buoy, however, he dropped the wet rope(绳). The boat moved away in the fog carrying

John. Because John didn't know how to use the radio(无线电波), the boat went around in all directions.

Twelve hours later, he was saved.

when a shout woke him up. A ship, the Good Hope, came up and he climbed onto it and thanked the
