What makes a good teacher?To be a good teacher, you need some of the gifts of a good actor: you must be able to 1 the attention and interest of your 2 ; you must be a clear speaker, with a good, strong, 3 voice which is fully under your control; and you must be able to act 4 you are teaching, so as to make 5 meaning clear. 6 a good teacher, and you will see that he does not sit motionless before his class: he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him 7 his explanations, and his face to express his feelings. Listen to him, and you will hear the loudness, the quality and the musical notes of his voice always 8 according to what he is talking about. The fact 9 a good teacher has some of the gifts of a good actor doesn’t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher’s work and 10 . The actor has to 11 exactly the same words each time he plays a certain part, even his movements and the way in which he uses his voice are usually 12 beforehand. What he has to do is to make all these carefully 13 words and actions seem natural on the stage. A good teacher works in quite a different way. His audience 14 an active part in his play: they ask and answer questions, they obey orders, and if they don’t understand something, they say so. The teacher therefore has to 15 his act to the 16 of his audience, which is his class. He cannot learn his part by heart, but must 17 it as he gets along. I have known many teachers who were fine actors in 18 but were unable to take part in a stage-play because their brains wouldn’t 19 discipline: they could not keep strictly 20 what another had written.
