My elder brother has decided to go with us. My father is so old that he has to stay at home and take care of

the house.

     We're going to take a train to New York, and then take a plane to Europe. When we arrive in Europe, we're

going to several countries for sightseeing. We'll go to places either by train or by bus. Then we're going to fly

home.

time. But my brother likes to take a boat trip and Jack enjoys that, too.
