答案

Johnson,

    I'm so glad to learn that you and your family are coming to settle down in China.

After a careful study of the information about the two cities, I suggest you choose to

live in City A. First of all, City A is a more popular city to live in. The environment

in City A is better than that in City B and the climate there is very pleasant. Besides,

there are many places for entertainment where you can enjoy yourselves in your spare time.

As for the employment, though the job opportunities are not so good as in City B, yet I

don't think it's a problem for you as a teacher of English.

    This is only my suggestion and it's up to you to decide. Hope to hear from you again.

                                                                                                                Yours, 

                                                                                                                 Li Hua
