Questions 24to 27are based on the following passage.  I have heard of the story of the world famous opera singer Tina Kiberg. As a child, Tina was a violinist and spent her free time practicing and practicing. One day she participated in a violin contest and realized that she would never be more than an ordinary violinist and that she enjoyed singing more. She gave up the violin, took up singing and became a leading international opera singer. Her courage to give up is what allowed her to become a world famous opera singer. Now try to guess what these somewhat successful people have in common-Larry Page,Tiger Woods,John McEnroe and John Steinbeck. Yes, they all dropped out of Stanford. Look at many other successful people and I bet their past is also filled with things they did at one time and then gave up. There are a number of cognitive(认知的processes that make it hard for us to leave our present situation and move ) on to something new—evenwhen we feel miserable with the present situation. We think “I’veinvested so much in this already. If I quit,all will have been wasted. M Once we have something,we hate to lose it. Things we don’thave yet don’tcarry the same value. These cognitive thoughts might help explain why people stay stuck in bad jobs, bad marriages, unhappy friendship,etc.  To sum up, sometimes you’vegot to stick with somethings even through tough times but sometimes you have to have the courage to give up. You have to be open to the fact that sometimes giving up is the right way forward.  24.What can be learned about Tina Kiberg?
