Yoko, a Japanese girl, has been an exchange student in the USA for two months. She’s now living with the Paul family on a farm 80 kilometers to the north of Las Vegas.

The Pauls are kind and friendly. There are four people in their family. Mr and Mrs Paul are hard-working people. They get up early every day and go to work on the farm right after breakfast. Their two children, Jane and Mike often help them after school. Since Yoko arrived, she has been learning a lot about life on a farm. In the afternoon, after learning, she helps the Pauls with farm work. She often feeds the animals and waters the vegetables. Sometimes she pumps water into the field.

In the evening, after dinner, the Pauls and Yoko often watch TV in the living room, drinking tea and chatting about their work, their plans for the next crops. Yoko feels as if she was in her family in Tokyo.
