[问答题]设计任务：请阅读下面学生信息和语言素材，设计20分钟的英语阅读教学方案。教案没有固定格式，但须包含下列要点：● teaching objectives● teaching contents● key and difficult points● major steps and time allocation● activities and justifications教学时间：20分钟学生概况：某城镇普通高中一年级（第二学期），班级人数40人，多数学生已经达到《普通高中英语课程标准（实验）》六级水平。学生课堂参与积极性一般。    语言素材：Good teacher    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.                                                                                              Watch a good teacher, and you will see that he does not sit still before his class: he stands 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.                                                                  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.     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 learnhis part by heart, but must invent it as he goes along.     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.
