参考范文：
Today’s society is of knowledge economy age,in which new knowledge emerges much faster than ever before.Moreover,knowledge plays an important part in the whole economy.Therefore,everyone finds it necessary to renew his (or her) knowledge, otherwise he (or her) will be left behind the society.
There are some ways to update knowledge.On the one hand, one can attend different courses at all types of schools,either part-time or full-time.On the other hand,self-study is, in a sense,a more convenient and practical method by which one can effectively renew his (or her) knowledge.
In my view,I have primarily depended on self-taught method in the recent years.Although I am busy doing daily work,I still insist on teaching myself at night.In this way,I can not only keep up with the swift development of society but also apply new knowledge to my practical work,which benefits me a lot.
