As a student, I was most afraid to answer questions in class, and I found that the students around were just like me. At the beginning of each class, when the teacher asked a question, I always lowered my head because I was afraid that the teacher saw me.
One day, in a foreign language class, Mr. Black gave us a lesson. He wanted us to be active in class. So he asked us some questions, but no one answered. "Let me tell you a story first, " he said.
"When I came to the United States to study, the university often invited famous people to make speeches. Before the beginning of every speech, I found an interesting thing. The students around me always took a cardboard folded in half, wrote their names in bold（黑体） with the mosteyecatchingcolor, and then placed the cardboard on the seat. So when the speaker needed the answers from the students, he could see and call a listener's name directly. "
"I couldn't understand that. My classmate told me the speakers were all top people, who meant chances（机会）. When your answer was to his surprise, it meant he might give you more chances. In fact, I really saw a few students got great chances because of that. "
After listening to the story, I understood that the chance will not find you itself. You must show yourself all the time so that you can find a chance on the card.
