    To build up our confidence and inspire us to make progresses，our school invited some outstanding graduates to give us a lecture last Friday.It was held in the lecture hall，lasted from 3pm to 5pm.
    During the lecture，the graduates show us how to make a practical learning plan.He also told us time management was greatly vital and balancing study and life was not to be ignored as well.Besides，they said nothing was most important than our own efforts.At last，they had expressed their best wishes to us.
