Almost everyone knows the famous Chinese saying：A young idler，an old beggar. Throughout history，we have seen many cases in which this saying has again and again proved to be true.
It goes without saying that the youth is the best time of life，during which one's mental and physical states are at their peaks. It takes relatively less time and pains to learn or accept new things in a world full of changes and rapid developments. In addition，one is less likely to be under great pressure from career，family and health problems when young. Therefore，a fresh mind plus enormous energy will ensure success in different aspects of life.
Of course，we all know：no pains，no gains. If we don't make every effort to make good use of the advantages youth brings us，it is impossible to achieve any goals. As students，we should now try our best to learn all the subjects well so that we can be well prepared for the challenges that we will face in the future.
My dearest family and friends,
It is difficult to express my gratitude and love to you all. I want to say so much, but I can hardly find the words. So I’ll just say that you are the greatest blessing in my life. This evening is the expression of your love to me, I realize this, but also it is the event when I see all of you gathered in the same place.
Thank you! Thank you for being with me all that difficult time. Your support and understanding gave me the strength to continue fighting. Without you I would give up. But then you would come or call and I would remember why I am so in love with this wonderful life-because of you. You are my world, and I am sincerely grateful to God for giving me such loving family and caring friends. Your support was crucial for me this year, when I achieved much due to your help.
Love and gratitude-this is what I feel standing now in front of you. Love and gratitude-these are the best emotions one can imagine. I am happy to love you and to be grateful to you. I know that you love me too. I would like to assure you that my goal in life is to become as wonderful as you think I am. As far as this goal attainment requires much effort, skills and time, I hope that you’ll help me in it, as always, I deeply appreciate your support. Thank you for being with me.
let me begin my speech with a replay of scenes familiar to most, if not all, of those present here today.
"mum, i'm sorry, but i need 3,000 yuan for my tuition this year."
"mum, it is my friend's birthday tomorrow, i must buy her a present."
"mum, this jacket was out of fashion long ago, would you do me a favor? "
take. take. take. the relationship between a mother and a child always seems to follow such a pattern. i know my mother is always there for me, providing me with everything i need; from food to clothing, from tuition to pocket money. i never thought twice about all she did until one day she said, "will there be a time that you'll say you have taken enough from me? "
like a child endlessly asking, we humans, throughout history, have been continually demanding what we desire from nature. we enjoy the comfort and beauty of our furniture, yet we never bother to think about the serious soil erosion caused by deforestation. we take it for granted that we must warm ourselves in winter times, yet we seldom realize the burning away of precious natural resources. we appreciate all the prosperity from the development of modern industry, yet few would give the slightest consideration to the global air and water pollution caused by industrial wastes. our ruthless exploitation has permanently impaired our mother earth. as we tragically learned from last summer's floods. we cannot continue our carelessness.
finally, standing here at the threshold of the 21st century, we cannot help thinking of our posterity. nature is not only the mother of the present generation, but also the mother of the generations to come. how severely our descendents will criticize us if we leave them a barren and lifeless mother? how much more they will appreciate us if we give them a world of harmony to inherit? let us start respecting and caring for nature from now on. let us start the campaign of.
