¡Hola! Soy Isatu y tengo 15 años. Tendré 16 años en la 16 de Augusto. Tengo una familia grande con tres hermanos más viejo y una hermana menor. Hoy, fui pescando con mi hermano y hermana. Fue muy divertido pero no tuvimos pescas grandes pero tuvimos muchos pescas pequeños. Mañana, vamos a pescar otra vez.

A Person who Has an Interesting Job [564]

A friend of mine is a tour guide whose job, I think, is very interesting because he has chances to travel to all sorts of tourist attractions around the world. Actually we were schoolmates when we attended middle school in my hometown, a small town in Hunan province. We got to know each other during the school years. He majored in tourism while in university. A few years ago, he passed a test for guide certification, so and he became a tour guide since then. He usually took tourists on overseas trips, such as Singapore, South Korean, and Japan, etc.
I think his job must be pretty interesting; you can imagine, traveling to different places, meeting different people, tasting various kinds of foreign foods.
Anyway, I wish I had chances to travel around the world some day.

Very cool. I wish I had a job like that!
