There is more in education than just 小题5:(1earn)facts．We go to school to learn how to learn，so that when we have left school we can continue to learn．A man 小题6:  really knows how to learn will always be successful，because when he has to do something new, he will not only be able to do it well himself, he will also be able to teach others  小题7:  to do it in the best way．The 小题8:  (educate)person，on the other hand，is either unable to do something new，or just 小题9: (do) it badly．The purpose of schools，therefore，is not to teach languages，arithmetic，history science，etc．，  小题10: to teach pupils the way to 1eam．
