Round The World

Mr. and Mrs. Spencer both had very busy jobs and didn' t have much time to spend with their young children. They wanted to change this, and because their hobby was boating, they, decided to sail round the world together.

It took six years to prepare everything for the trip. First, they bought a new boat. Then, both the husband and wife had to take advanced (先进的) sailing lessons and learn all about the sea and the weather. Mr. Spencer also did several courses（课程） in repairing engines and Mrs. Spencer spent an hour in a restaurant learning to cut up fish.

In October they had one year off from their jobs and sailed away from England with their two children. The next year, in August, their long journey ended in Australia.

The boat was not big, but they took a teacher for the children with them. None of them found the trip boring because there were three computers, many CDs, a TV and a DVD player on the boat.

The family loved being at the sea and seeing the stars in the sky. But, most of all, Mr. and Mrs. Spencer enjoyed playing with their children while they were still young.
