homework ,come to show my wrongs ~ Not long ago , Olympics games was held in Brazil and our country sent the best sporter to join the games. However, America, as twice as our country's gold mental amount, capture the most of gold metal as always. So review our country sport career development and compare with America, i think "enthusiasm" is one of the most important and decisive thing in children's education. There is a saying going that "The best teacher is no more than enthusiasm", i have to say i can't no more agree that because i can't play any melody on acoustic before May in this year. But, finally i achieve it and the process is difficult and bitter. I can't fallow the beat or keep the melody in my head until i practice it repeatedly ,more than one hundred times. However, i accomplish my wish that play a song frequently in front of anybody. If there were no any enthusiasm in music, i must practice it no more than 10 times so that i would not gain anything in the future.I think it is the common sense in any cases thus i suggest that school should timely find children's interest and keep them as far as he can.
