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 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.

　　要成为一个好老师，你需要一些好演员的天赋;你必须能够抓住观众的注意力和兴趣;你必须是一个明确的扬声器，具有良好的，强有力的，悦耳的声音完全在你的控制之下;你必须能够按照你的教学，以明确其含义。

　　Watch a good teacher, and you will see that he does not sit still before his class： he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings. Listen to him, and you will hear the loudness, the quality (音色) and the musical note of his voice always changing according to what he is talking about.

　　看一个好老师，你会看到，他不坐他的课前，他代表整个时间他是教学;他走，用他的胳膊，手和手指来帮助他解释，他的脸表达感情。听他的，你会听到声音，质量(音色)和音乐注意到他的声音总是按照他所说的。

　　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 on 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 (预先). What he has to do is to make all these carefully learnt words and actions seem natural on the stage.

　　事实上，一个好老师有一些好演员并不意味着礼物，他一定能够在舞台上表演好，有教师和演员的工作的。他说的话他熟记于心的很重要的差别;他必须准确地重复同样的话每次他扮演某个角色，甚至他的动作，他用自己的发音方式都是事先确定的(预先)。他所要做的是让这些用心学习的言语和行动似乎自然的舞台上。

　　A good teacher works in quite a different way. His audience takes 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 meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.

　　一个好老师的工作相当不同的方式。他的听众积极参与他的表演：他们提问和回答问题，他们服从命令，如果他们不理解的东西，他们这么说。老师必须满足听众的需要，这是他的学生。他不能了解他的心，但必须把它作为他走。

　　I have known many teachers who were fine actors in class but were unable to take part in a stage-play because they could not keep strictly to what another had written.

　　我知道有许多老师在课堂上是优秀的演员却不能在舞台上扮演角色，因为他们不能严格按照别人所写的。
