Dear Jim,
I am so please to hear from you
and I’m writing to tell 71
you anything about
my school. You are right. Quite a few 72
changes have been
taken place in our school. On one side 73
of the road, there is a new
teaching building. On other 74
side, where the playground used to
be, now stand
75
another new building. It is ours
library. In it, there are all 76
kinds books, newspapers and
magazines. The playground 77
now is in the front of our school.
We also have planted many
78
tree around our school. I hope you

a visit in our school yourself
some day in the future.
