To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your students, you must be 　36　—speaking, with a good, strong,　37　 voice which is fully under your control; and you must be able to 　38　 what you are teaching, in order to make its meaning clear.
　39　 a good teacher, and you will see that he does not sit still before his class; he 　40　 the whole time he is teaching; he walks about, using his 　41　,hands and fingers to help him in his explanations, and his face to express his 　42　.Listen to him, and you will 　43　 the loudness, the quality and the musical note of his voice always 　44　 according to what he is talking about. The fact that a good teacher has some of the gifts of a good actor doesn't 　45　 that he will indeed be able to act well on the stage, for there are very important 　46　 between the teacher's work and the actor's. The 　47　 has to speak words which he has learnt by heart; he has to repeat exactly the 　48　 words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually 　49　 beforehand. What he has to do is to make all these carefully learnt words and actions seem 　50　 on the stage.
A good teacher 　51　 in quite a different way. His students take an active part in his 　52　:they ask and answer questions, they obey orders, and if they don't 　53　 something, they will say no. The teacher therefore has to suit his act to the needs of his students, which is in his class. He cannot learn his part by heart, but must 　54　 it as he goes along.
I have known many teachers who were fine 　55　 in class but unable to take part in a stage play because their brains wouldn't keep discipline: they could not keep strictly to what another had written.
