[解析]
(1)D.细节理解题。根据第二段的The magician must keep people from noticing all the movements of his hands and from thinking about the secret parts of his equipment.He must also lead the audience to draw false conclusions.The magician's success depends on the fact that many things seen by the eye are not the things that matter.(魔术师必须防止人们注意到他手上所有动作,以及思考魔术道具的秘密部分。他还必须引导观众得出错误的结论。魔术师的成功取决于这样一个事实:许多肉眼看到的都不是重要的。)可知,魔术师最重要的是要引导观众的注意力。故选D。
(2)B.猜测词义题。根据划线词所在句的后一句While doing this he talks to the audience and waves a brightly coloured cloth with one hand.(在这样做的同时,他与观众交谈,并用一只手挥舞着一块色彩鲜艳的布。)可知,魔术师要通过手的动作来完成魔术,由此可推知,划线词employing与"using"同义,表示"使用"。结合选项A.Hiring雇佣;B.Using使用;C.Engaging忙于,订婚;D.Moving移动。故选B。
(3)D.推理判断题。根据倒数第二段第一句Two basic magic tricks are making objects seem to appear and making objects seem to disappear.(两个基本的魔术是让物体凭空出现或消失。)及倒数第一段的Another favourite trick is to cut or burn something,and then make it appear whole again.(另一个最受欢迎的魔术是切断或燃烧某物,然后再让它变完整。)可知,这两段都是通过举例子的方式展开叙述的。故选D。
(4)A.主旨大意题。根据文章第一句Magic is a form of entertainment that is based on pretending to do things that are impossible.(魔术是一种娱乐方式,基于假装做一些不可能的事。)对魔术的概述,结合后文列举例子详细揭示魔术的过程可知,本文主要揭示了魔术背后的秘密。故选A。
