My school has taken on a new look since it moved into a new
place.It is quite different of the old one.It used to be only one
classroom building and the playground is not large enough for all the
students to have sports on.Sometimes we had to practice run along
the streets outside.The teaching conditions were even worst.Our
teachers used to teach with only a blackboard and chalk and the
experiments could only be done in the classroom.But now besides the
classroom building,a modern lab building has also put into use,which
all kinds of experiments can be done.We have not only a large
playground and also a gym.Classes can be given by the help of
computers and multimedia.What are great changes!I feel proud of my
school.
