浮生若梦圈
你们老师有病......你这样吧：Good morning/afternoon/evening everyone. It is a great honour to be here and deliver this speech. My topic today is about some misconception about A/H1N1 virus. Before I start, let be present my credentials to you. （然后加一段你有什么什么证书，什么学位，有什么工作经验之类的。）之后过渡一下，后面加写文章的目的。哦，演讲考试这么说就可以啊。这个绝对可以拿到随便什么地方去说的。绝对正式。
