　　Dear Roni,

　　Italy is wonderful. We started in Rome two weeks ago, drove to Florence last week and now we're on our way to Venice. Three weeks just isn't enough.

　　The country near Florence is so beautiful－hills, olive trees. And red roofs(屋顶) of the houses look so nice far away.

　　I am afraid I am getting bigger－the food here is so delicious!

Love,

Akemi

　　Hi Roni,

　　I can't believe(相信) you went to school here in Honolulu! Why did you leave?

　　I spend each morning on the beach(海滩) and in the water. The sand is so soft and the beaches seem so long. The water is just the right temperature.

　　One afternoon, I left the beach to walk in mountains near Honolulu. I enjoyed myself very much there.

　　How I miss you!

　　Dear Roni,

　　Maybe I'm strange but I love the desert(沙漠)!

　　Last week, our group spent four days in the desert. At times, it felt like the moon.

　　I always thought deserts were all the same! They are not. Some parts look like mountains; others are really different.

　　And when we find something green－－a few plam trees, a little water, we feel good and great.

　　See you in September,

Kim
