1______To be a good teacher, you need some of the gifts of a good actors: you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear．
2______Watch a good teacher, and you will see that he does not sit unmoved before his class: he stands the whole time he is teaching; he walks about, using his arms, his hands and fingers to help him in his explanations, and his face to express feeling．Listen to him, and you will hear the loudness, the quality and the musical note if his voice always changing according to what he is talking about．
3______The fact that a good teacher has some of the gifts of a good actor doesn’t mean that he will indeed be able to act well in the stage, for there are very important differences between the teacher’s work and the actor’s．The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand．What he has to do is to make all these carefully learnt words and actions seem natural; on the stage．
4______A good teacher works in quite a different way．His audience takes an active part in his play: they ask questions, they obey orders, and if they don’t understand something, they say so．The teacher therefore has to suit his act to the needs of his audience, which in his class．He cannot learn his part by heart, but must invent it as he goes along．
5______As a good teacher presently, you must take your audience as your friends, take care of them, help them and give them enough freedom and space．I have known many teachers who were fine actors in class but were unable take part in a stage play because their brains wouldn’t keep discipline: they could not keep strictly to what another had written．
D/A/B/C/ AC
