【答案】Dear Miss Evans，
   How are you getting along？My eyesight has declined seriously，which makes me not see things around us clearly.I feel very anxious about it and I am writing to ask for some helpful suggestions from you.
  I guess there are two reasons which cause my problem.For one thing，I am addicted to my mobile phone these days and sometimes I even play games on the phone for a long time.For another，I am lacking in enough exercise.I know you have excellent eyesight.Could you put forward some practical proposals？I would appreciate it if you can respond at your earliest convenience.
Yours sincerely，
Li Hua
