Mr. Smith, it is a notice to the audience. It says that we should enter the concert hall 30 minutes earlier before the concert starts. Entrance to the hall is by ticket only, each one each ticket. As a rule, food or drink should not be taken into the hall. Of course, smoking is not allowed in the hall either. Please don't bring your digital camera with you because no photos can be taken during the concert. And what is more, beepers and mobile phones must be off during the concert.
点评：文章的用词和句式有一定的难度，特别是关联词的运用，如of course, as a rule, and what is more使文章读起来朗朗上口，层层紧扣，环环递进，体现了作者较高的写作技巧和水平。
