Let us learn to understand happiness First of all,I have to tell you I wrote this article to attend a spoken English competition and I won the second prize.I just want to write it again and share it with you all.I am willing to see your comments! My topic is let us learn to understand happiness.Someone think owning a large amount of money is happiness.Someone think staying with their family members is happiness .In a word,different people have different attitudes to happiness. I want to give you all an example of Dr Yuan . Yuan Longping,an agricultural scientist in China.He was born in 1930 in a poor farmers family and graduated from Southwest Agricutural college in 1953. His life goal is to finding ways to increase the rice output without expanding the area of the fields.He did all he can to do his research.He has struggled for the past five decades .In 1970,in cooperation with others,he was able to cultivate what is called the super hybrid rice.Due to his work,China's total output rose from 50 million tons in 1950 to nearly 200 million tons.He also circulated his knowledge in many other less developed countries. He is quite satisfied with his life.He likes playing mahjong,listening to violin music and swimming.Fame or money means very little to him.The most happiest thing for him is to go on working hard at his super hybrid rice project because he loves and cares for his people. In my opinion ,trying your best to help others is the most happiest thing.So let us learn to understand happiness. Sorry,time for lunch.So I don't finish the whole composition,it still has another example of myself to say but I have no time.
