If ever you are called【B1】to intro-duce a speaker, it would be well for you to bear in【B2】

that you have a responsibility to do more than simply get up, recite a few facts, and then sit down. You have at least five major【B3】.

Most speakers are【B15】to talk about their own accomplishments, and it is your job to【B16】out beforehand what these accomplishments are and then tell your audience about those that seem most interesting. This requires some【B17】ahead.【B18】you will have referred to the speaker, possibly by name and title, before you formally introduce him, it is always a good idea to【B19】the title or substance of his topic as【B20】as his name and title near the close of your introduction.
