During recess and lunch time we can use computers and raise our computer skill.

In our school, there are at least one computer installed in every classroom. Doing research or enhance learning is only one click away. During recess or lunch break, we have the opportunities to work on the computer. These in turn improve our computer skills as well.

我建議這樣寫：
In our school, there is a computer in all classrooms. It is very convenient for us to search for information while learning. During recess and lunch time we can make use of computers to enhance our computer skills.

In our school, every classroom has a computer or more.此句似港式英文,我建議改成
In our school, there's at least one computer in every classroom.

It is very convenient for us to search something for our learning. 建議改成

建議改成
