The following words and phrases may help you. Answer Madam chairperson, delegates, dear athlete participants and young girls. I feel extremely delighted to find India being represented in this Meet through you all.
I feel honoured to speak to you a few words from this platform. Well, I was once like you. What is important in life is self-confidence. You must be sure that you are on a correct path of life. It should be morally right also. You must set a goal also. In between lie your hard work, determination and faith in you. You must make a kind of chart of your activities.
You must see the goal as the motivating factor. They motivate you to do unusual things. But dreams should be capable of being fulfilled. Never allow difficulties to overpower you. You will face problems in life. But never let them discourage you. Keep these things in mind. Believe in your physical and mental capacities. I am sure success will be yours. Write a short article for your school magazine comparing and contrasting the players in terms of their duration at the top.
Mention some qualities that you think may be responsible for their brief or long stay at the top spot. The list is long. Different women enjoyed life being of the summit for different durations. For instance, Steffi Graf of Germany enjoyed the topmost rank for the longest duration of weeks on August 17, Martina Navratilova of the US enjoyed it for weeks on July 10, It was Martina Hingis of Switzerland who had it for weeks on March 31, Monica Seles of the US also enjoyed it for weeks on March 11, Following this, Serena Williams and Lindsay Davenport of the US also remained world number one for 57 and 82 weeks respectively.
The latest number one women player is Maria Sharapova of Russia. She enjoyed this rank for 1 week only on August 22, They worked very hard day and night. They sharpened their playing skills through various hurdles. They had physical fitness and mental strength to get success. They had talent, mental toughness and readiness to sacrifice. These qualities played an important role in their world achievements. They have proved a great point. It is : if any one has these qualities of head and heart, one can surely achieve this grand success.
Dreams always motivate one. But those dreams should be worth putting into practice. Which of these words would you use to describe Santosh Yadav? Answer I would use the following words to describe Santosh : determined, adventurous, considerate, persevering. Santosh is surely a girl of determination. While young, she determined to get more education.
For that she made her father agree to that. She threatened her parents that she would never marry if she did not get a proper education. Then she was very much determined in her career. She joined the Nehru Institute of Mountaineering at Uttarkashi without their permission. She is adventurous also.
She used to see the villagers climb the Aravalli Hills in Jaipur and vanish after a while. She decided to check it out herself one day. She is considerate. She has a sacrificing nature also. She provided special care to a climber who lay dying at the South Col.
She saved another climber, Mohan Singh. She gave her oxygen to save him. Without that he would have died. She had enough perseverance in what she did. This sharpened her climbing skills. This also increased her physical fitness and mental strength. Because of this she climbed Mount Everest.
