Dear Nancy,

    Thanks for your letter. I'm happy(hear) that you're getting on well with your study in Australia. You(leave) your home town five years ago, so you must want to know something about life here. Things in Jinhua(be) not the same before. Now almost every family has computer. We often communicate（交流）with each other by email.

    There are many tall buildings in(city) and also in the countryside. The roads are much(wide) and cleaner. But the population here gets larger larger. We often climb the mountains on weekends and have great fun. You can write me. We can write to each other(much) often.

Your friend,

Jimmy
