To discuss this matter, I'd like to call on Mr. Johnson. 关于这一问题，我想请约翰先生发言。
Let's move/pass on to the next item on the agenda. 让我们继续议程的下一项议题。
Next, let's focus on production figures. 接下来，我们将焦点集中到生产数据。
半个句型要记牢
call on (请求)
Tip:
完整的结构应该是call (up) on sb. to do sth. ，意思是"叫(请)某人做某事"。如 Then the teacher called on me to answer the question. (这里老师叫我回答问题)，We are calling on you to help us. (我们恳请你帮助我们)。另外，还可以表示"号召某人做某事"。如The Party called on us to study hard for the people. (党号召我们要为人民努力学习。)
