3句英文任你選

All right, ladies and gentlemen, I declare the meeting open.
好了，女士們、先生們，我宣布會議開始。

It is an honor for me to declare the conference open.
很榮幸由我來宣布會議開幕。

Let's call the meeting to order.

半個句型要記牢

declare the meeting open (宣布會議開始)

Tip:

declare這里表示"宣布，宣告注意易與announce混淆announce更接近于漢語"公布"、"告知"的意思，它所涉及的是一件對方原來不知道的事。如: The accident was announced to his family by telephone. (警方已將事故用電話告訴了他的家屬。); declare含有莊嚴(yán)宣告或交代清楚的意思，它所涉及的事不一定是對方事先所不知道的。如: The accused declared himself to be CBS innocent. (被告宣稱自己無罪。)。另外會議開場白還可以說Let's begin the meeting. Let's get started. (我們開會了。)
