Dear Tommy,

I’m in Paris now! Mom, Sally and I came here to visit my uncle. We are having a wonderful time. Dad didn’t come because his company (公司) sent him to work in Japan last month. He will have to stay there until November.

For Sally and me, it’s our first time to come to France. We are so excited! Last week Mom went to different shows alone. She used to study in Paris, so she knows the city well. Sally and I visited many interesting places with Aunt Susan. Although we can’t speak French, it’s OK. Aunt Susa n and Uncle Tyler can speak both French and English.

Yesterday afternoon, Mom, Sally and Aunt Susan stayed home cooking dinner. Uncle Tyler took me fishing. We drove for an hour and finally arrived at his favorite lake. First, we walked around the lake looking for a good place to fish. Uncle Tyler said we should fish from the top of a large rock.

I was so interested in catching a fish that when I threw my fishing line and hook (鱼钩) out, the rod (鱼竿) went with them! Uncle Tyler got my rod out of the lake. Then he said that next time, I should wait until he put bait (鱼饵) on the hook.

We fished for two hours and my uncle caught four fish. He is a fantastic fisherman. The only thing I caught was a cold. I can’t wait to go again soon, so I can become a great fis herman like him.

Yours,
