19．　　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 (折叠的) in half, wrote their names in bold with the most eyecatching color, 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 classmates told me the speakers were all top people, who meant chances. 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.

20．　　Note-taking is a skill that can help you do well in all your schoolwork. It can make you confident when you are studying. But unluckily, most students don't know how to take notes.
　　If your teacher writes notes on the blackboard, that's great. You can copy them or write down the most important facts of all in class. Different teachers do things differently. For example, some teachers may focus on (关注) lots of dates and facts in class, but they only write the important ones on the blackboard. Other teachers may not write anything down, but they may repeat them.
　　Don't try to write down every word in class, or you might miss some important points. Some students really learn better with the help of these notes.
　　Don't be afraid to ask your teacher to repeat what you're missed. If your teacher speaks too fast and you can't follow what he is saying, you can ask him after class.
　　Comparing (对比) your notes with your classmates' can be good for your learning. It can also help you
and your classmates correct some mistakes.
　　Note-taking also needs organization. Keep notes for each subject in one place, so that you can find everything easily when a test comes.
　　Good note-taking takes time. If you decide to recopy your notes every evening, you'll surely have less time to watch TV. But you'll save time in the coming test.
