The summer vacation had come round again。 I was happy that I could forget about school at least for a while。 Lest I fool around all through this summer vacation， I made a plan as to how to spend it。 First， I thouge forms of exercise， such as walking， running rowing， to keep me physically strong。 It stood to reason that with such a good plan I should make the best of my vacation time。 I did， because I lived up to what I had planned。
