Mary is my best friend. We’re all from Henan, (46) but now I live in Beijing when she lives in (47) Guangzhou. We don’t look each other very often, (48) but we’re keep in touch all the time. I often write (49) to Mary and telling her about the things that (50) are happened at my company, and she often (51) writes to me about her work. We talk on phone (52) once a week. Sometime I call her on her (53) car phone, or we send e-mail to each other. (54) We’re really luck. There are so many ways (55) we can keep in touch with each other.
