15．Dear Xiao Fang，
How time flies!It is two years since you moved to America for your study．（57）C
How happy we are!During your staying in America，little companions（小伙伴们 ） kept complaining，"There is no one to play with．"Huang Lei talked about the little woods where we often played together．（58）DEach time I saw your empty house next door，I held back tears．How much I have missed the days when we played in the woods behind our houses，where we dug up some worms，chasing the birds．I still remember we slipped down along the stream，feeling the spray（浪花） on our faces．
After reading your letter，Huang Lei and I came up with an idea．How about our families spending a week's vacation together this summer？（59）A It is located between the downtown of Chunxi and
Wulin Town where we used to have fun．July will be the best month for us，so we must enjoy freedom and joy for a long time．（60）BI can't wait to look forward to the time when we meet again．
Yours
Xiao Mei
