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 thought i should go over all those things my teachers taught in the previous term so that i could have a better understanding of them. then i thought i should take up some forms of exercise， such as walking， running and 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._ __
